The role of the gut microbiota in carcinogenesis is increasingly being acknowledged. Recent studies in multiple breast cancer mouse models have found that antibiotics, by altering the gut microbiota, can accelerate tumour growth. In humans, a recent cohort study restricted to triple negative breast cancer showed that breast cancer patients using a greater number of antibiotics had markedly worse survival. These studies have raised concerns about repeated antibiotic use in breast cancer patients. In this Registered Report, we investigated whether breast cancer patients using oral antibiotics had increased breast cancer-specific mortality. In population-based cohorts (n = 44,452), we did not observe a statistically significant association between antibiotic prescriptions after diagnosis and breast cancer-specific mortality (adjusted HR = 1.07 95% CI 0.87, 1.33) apart from prescriptions of 12 or more antibiotics (adjusted HR = 1.62 95% CI 1.31, 2.01). This association was weaker after adjustment for infections (adjusted HR = 1.44 95% 1.14, 1.81), when restricted to antibiotics within five years (adjusted HR = 1.33 95% 0.95, 1.84), and was similar for deaths from other causes (adjusted HR = 1.69 95% 1.19, 2.41). Frequent antibiotic users had higher cancer-specific mortality but the attenuation of associations in sensitivity analyses, and similar findings for other causes of death, suggest this increase may reflect residual confounding.

Objectives Mental contrasting with implementation intentions (MCII) is an effective self-regulation strategy for goal pursuit. Although it is a quick and cost-effective strategy, most of its applications have consisted of single-time training. Building on the existing research on bedtime procrastination, we propose that daily MCII applications can lead to more efficient pursuit of bedtime goals. Furthermore, we evaluate the conditions where MCII training could be more advantageous for people with different types of goal motives. Methods and Measures We recruited 297 participants via Prolific and randomly allocated participants into either daily MCII or single MCII groups for a week-long diary study. We measured goal motives, goal-regulatory variables, bedtime procrastination, and affect to test our hypotheses. We conducted a multilevel structural equation modelling using Mplus. Results Participants who completed MCII daily reported less bedtime procrastination than individuals who performed MCII one-off at the start of the week. Participants experienced increased positive affect and decreased negative affect when they procrastinated less. Autonomous goal motives were not associated with bedtime procrastination. Discussion Daily MCII appears as an effective and easy-to-implement strategy helps reducing bedtime procrastination. Future research should test the effectiveness of daily MCII in other contexts.

Over the past two decades, the number of stock buybacks by U.S. corporations has increased tremendously. While buyback anomalies have been investigated in the U.S., identifying whether they are also observable out of the U.S. markets, such as in Japan, is challenging yet necessary. This pre-registered report seeks to reveal whether buyback anomalies persist for longer periods in Japan's stock market. We focus on whether the “costly arbitrage view” supporting buyback anomalies in the U.S. market applies to the long-term buyback announcement returns in Japan's stock market. This study also focuses on whether bank ties in bank-based (financial) systems mitigate long-term excessive stock returns due to buyback anomalies. We shed light on regulatory discussions regarding the restriction of corporate buybacks. Our study contributes to determining whether bank monitoring is effective in mitigating the degree of buyback anomalies in bank-based systems.

Context effects occur when the preference between two alternatives is affected by the presence of an extra alternative. These effects are some of the most well studied phenomena in multi-alternative, multi-attribute decision making. Recent research in this area has revealed an intriguing pattern of results. On the one hand, these effects are robust and ubiquitous. That is, they have been demonstrated in many domains and different choice settings. On the other hand, they are fragile and they disappear or even reverse under different conditions. This pattern of results has spurred debate and speculation about the cognitive mechanisms that drive these choices. The attraction effect, where the preference for an option increases in the presence of a dominated decoy, has generated the most controversy. In this registered report, we systematically vary factors that are known to be associated with the attraction effect to build a solid foundation of empirical results to aid future theory development. We find a robust attraction effect across the different conditions. The strength of this effect is modulated by the display order (e.g., decoy top, target middle, competitor bottom) and mode (numeric vs. graphical) but not display layout (by-attribute vs. by-alternative).

While absolute pitch (AP)—the ability to identify musical pitches without external reference—is rare even in professional musicians, anecdotal evidence and case-report data suggest that some musicians without traditional AP can nonetheless better name notes played on their musical instrument of expertise than notes played on instruments less familiar to them. We have called this gain in AP ability “instrument-specific absolute pitch” (ISAP). Here, we report the results of the first two experiments designed to investigate ISAP in professional oboists. In Experiment 1 (n = 40), superiority for identifying the pitch of oboe over piano tones varied along a continuum, with 37.5% of oboists demonstrating significant ISAP. Variance in accuracy across pitches was higher among ISAP-possessors than ISAP-non-possessors, suggestive of internalized timbral idiosyncrasies, and the use of timbral cues was the second-most commonly reported task strategy. For both timbres, both groups performed more accurately for pitches associated with white than black piano keys. In Experiment 2 (n = 12), oboists with ISAP were less accurate in pitch identification when oboe tones were artificially pitch-shifted. The use of timbral idiosyncrasies thus may constitute a widespread mechanism of ISAP. Motor interference, conversely, did not significantly reduce accuracy. This study offers the first evidence of ISAP among highly trained musicians and that reliance on subtle timbral (or intonational) idiosyncrasies may constitute an underlying mechanism of this ability in expert oboists. This provides a path forward for future studies extending the scientific understanding of ISAP to other instrument types, expertise levels, and musical contexts. More generally, this may deepen knowledge of specialized expertise, representing a range of implicit abilities that are not addressed directly in training, but which may develop through practice of a related skill set.

A live discussion experiment was designed to test the effects of highly empathic (vs. moderately empathic) listening on solitude experiences. Participants were assigned to three conditions in which they: 1) Discussed a negative personal experience with a confederate (ostensibly another participant) exhibiting highly empathic listening; 2) Discussed an experience with a confederate exhibiting moderately empathic listening; or, 3) Engaged in a positive reframing exercise. Building on previous listening theory (Weinstein et al., 2022) and research (Itzchakov & Weinstein, 2021; Itzchakov, Weinstein, et al., 2022). We then assessed the two posited mechanisms of autonomy and relatedness and tested the expectations to be in solitude. All participants were instructed to spend ten minutes alone, phones off, and distractions stored away. While highly empathic listening enhanced participants' (i.e. speakers) autonomy and relatedness need satisfaction compared to the other two conditions and predicted initial increases in self- and social-connection, it did not subsequently improve solitude experiences, with no direct effects found predicting self-connection, peaceful affect, loneliness, or self-insight. Indirect effects linked empathic listening to self-connection and self-insight through autonomy satisfaction. While empathic listening fosters immediate psychological need satisfaction in social contexts, deeper listening interventions may be necessary to improve subsequent solitude periods.

This registered report examines the effect of motor disruption in the conscious control of behavior (i.e. executive function – EF) of three-year-old children in the Southern United States (N = 114). Specifically, we investigated how disrupting a relevant motor response influenced performance on two EF tasks. Each EF task had an initial phase intended to form a habit, and a switch phase that was the critical measure of EF. Children must inhibit the habit developed at the beginning of the task and reflect consciously on new demands. The multistep multilocation task examined the inhibition of a motor-based habit (response shift), while the Dimensional Change Card Sort examined the inhibition of a cognitive-based habit (attention shift). The motor disruption consisted of administering weighted armbands at two time points during the tasks (i.e. the beginning of the task or during switch trials only) to disrupt reaching behavior. Motor manipulation was found to have a differential effect on EF tasks among three-year-old children. While the armbands improved performance on the response shifting task relative to a no armband control condition, they did not significantly affect performance on the attention shifting task. Contrary to expectations, the armbands did not lead to more errors (habit disruption) during pre-switch trials in either task. These findings highlight the significance of considering both motor and cognitive factors in early childhood EF development. Further research is needed to explore the underlying mechanisms and implications of incorporating movement in EF development.

Research on approach/avoidance training (AAT) effects shows that approach (i.e., reducing the distance between the self and a stimulus) leads to more positive evaluations of stimuli than avoidance (i.e., increasing the distance between the self and a stimulus). The present experiments relied on a grounded cognition approach to extend this finding by investigating the framing-dependency of AAT effects on facial representations of target stimuli. In a Preliminary Experiment, using antagonistic types of approach (affiliative vs. aggressive) and a reverse correlation paradigm, we found that approach led to more positive facial representations than avoidance when approach was portrayed as affiliative, but this effect decreased and tended to reverse (i.e., yielding more negative facial representations) when approach was portrayed as aggressive. Two registered experiments extended these results while also addressing important limitations of the Preliminary Experiment. First, to prevent any contrast emerging from the joint use of approach and avoidance, Experiment 1 isolated the unique effects of affiliative approach, aggressive approach, and avoidance compared to a control action. We also explored whether aggressive approach and avoidance (two negatively valenced yet distinct actions) produced negative effects characterized by divergent outcomes on facial features (e.g., weak vs. dominant). Second, Experiment 2 tested the importance of the experiential component of approach/avoidance actions by comparing the AAT with a mere instructions condition. Results of Experiments 1 and 2 proved consistent with a framing-dependency of AAT effects. Unveiling the framing-dependency of AAT effects challenges some of the current theoretical views on AAT effects.

Personality dysfunction is a core element of the diagnosis of personality disorders in both main diagnostic systems (Diagnostic and Statistical Manual of Mental Disorders [5th ed.] Personality Disorders and ICD-11 [International Classification of Diseases, 11th Revision] Personality Disorders). A recent study by Sleep et al. explored the structure of personality dysfunction (N = 517 undergraduates) with exploratory bass-ackward factor analyses at the item level using items from six measures of personality functioning. The present study represents a replication of the study by Sleep and colleagues in a community sample of individuals currently in or seeking psychological/psychiatric treatment. Participants were recruited from Prolific who completed items from six measures of personality dysfunction (N = 457). The primary factor analysis identified three lower-order factors of impairment (Negative Self-Regard, Disagreeableness, and Intimacy Problems). These dysfunction factors showed moderate to strong relations to the factors generated by Sleep et al.; however, there were important differences in the overall structure suggesting a lack of formal replication.

Despite the importance of psychopathy—a construct with robust relations with externalizing outcomes—little is known about how psychopathic traits manifest in middle-age to older adulthood. In the present investigation, we used a large and diverse sample of older adults from the St. Louis Personality and Aging Network to examine psychopathy’s nomological network and whether these traits change over four time points spanning approximately 10 years. We also explored whether these changes were associated with changes in other important constructs (e.g., physical and psychological functioning) across the same time span. Psychopathy was operationalized in two ways: (a) via the factors of the triarchic psychopathy model, Meanness, Disinhibition, and Boldness, and (b) using a more macro approach via the Five-Factor Model Psychopathy Resemblance Index. We found that (a) the nomological network of psychopathy appears to be consistent with what has been observed in samples of younger adults, (b) psychopathic traits remain stable over time as adults make the transition from midlife to later life, and (c) changes that were observed are significantly related to changes in several important outcomes, including physical health, mental health, relationship satisfaction, intimate-partner aggression, and social functioning.

Purpose:This registered report aimed to replicate previous findings showing that years of music training predicts speech-perception-in-noise (SPIN) skills in children. In addition, it aimed to investigate whether the musician SPIN advantage is influenced by cognitive factors such as general intelligence or working memory.Method:Following planned sample size estimations and analyses, 62 school-age children with varying degrees of music training participated in the study. Children's general intelligence quotients, working memory, and SPIN skills were assessed during one visit to our laboratory. We implemented hierarchical multiple regression analyses to examine the study aims.Results:Our regression analyses indicated that years of instrument training did not significantly account for variance in SPIN skills. The explanatory power of our model was enhanced only when working memory, particularly auditory working memory, was included as a predictor. Auditory working memory was associated with both SPIN skills and years of instrument training.Conclusions:Our study was unable to replicate previous findings that linked years of instrument training to SPIN skills in childhood. This suggests caution regarding prior claims that music training can be used with children to optimize learning in noisy environments. However, we did find evidence that musicianship is associated with enhanced auditory working memory skills, which could have positive implications for children's lifelong outcomes.Supplemental Material:https://doi-org.proxy.lib.duke.edu/10.23641/asha.28373786

Reactions to privilege include hostility (e.g., denial of privilege) and prosociality (e.g., remorse). Studies suggest that White Americans often react hostilely when confronted with racial and class privilege, but research on reactions to religious privilege is limited. The current registered report investigated how religiousness is related to hostile and prosocial reactions to religious privilege. Three studies tested the relationship between religiousness and reactions to religious privilege. In Study 1, a correlational study, we expected parochial religious variables (Christian nationalism, religious fundamentalism, perceptions of religious threat) would be related to hostile reactions to religious privilege, whereas more universal dimensions of religiousness (intellectual humility, gratitude toward God, and sanctification of social justice) would be related to prosocial reactions. Study 2 induced actual reactions to being confronted with religious privilege, manipulating whether privilege was framed as a merit-based or a group-based threat. Study 3 primed universal and parochial religiousness to examine the causal relationship between religiousness and reactions to privilege. Across our studies (Study 1 N = 395, Study 2 N = 737, Study 3 N = 699), parochial religiousness was related to hostile reactions, whereas two forms of universal religiousness (religious intellectual humility, sanctification of social justice) were related to prosocial reactions. Merit-based information about religious privilege decreased denial, whereas a religious humility intervention increased denial. Further research is needed on interventions to increase prosocial responses. (PsycInfo Database Record (c) 2024 APA, all rights reserved)

Across three studies, Murray, Rose, Bellavia, Holmes, and Kusche (2002) found that low self-esteem individuals responded in a negative manner compared to those high in self-esteem in the face of relationship threat, perceiving their partners and relationships less positively. This was the first empirical support for the hypothesized dynamics of a dependency regulation perspective, and has had a significant impact on the field of relationship science. In the present research, we sought to reproduce the methods and procedures of Study 3 of Murray et al. (2002) to further test the two-way interaction between individual differences in self-esteem and situational relationship threat. Manipulation check effects replicated the original study, but no interaction between self-esteem and experimental condition was observed for any primary study outcomes.

This study is a direct replication of gaze-liking effect using the same design, stimuli and procedure. The gaze-liking effect describes the tendency for people to rate objects as more likeable when they have recently seen a person repeatedly gaze toward rather than away from the object. However, as subsequent studies show considerable variability in the size of this effect, we sampled a larger number of participants (N = 98) than the original study (N = 24) to gain a more precise estimate of the gaze-liking effect size. Our results indicate a much smaller standardised effect size (dz = 0.02) than that of the original study (dz = 0.94). Our smaller effect size was not due to general insensitivity to eye-gaze effects because the same sample showed a clear (dz = 1.09) gaze-cuing effect – faster reaction times when eyes looked toward vs away from target objects. We discuss the implications of our findings for future studies wishing to study the gaze-liking effect.

In two experiments on hypothetical purchase decisions, Sussman and Olivola (2011) found that US citizens prefer avoiding tax-related costs over avoiding tax-unrelated monetary costs of the same size. The original Experiment 1 and 2 tests of this Tax Aversion indicated that people are willing to wait longer to receive a discount when it refers to taxes (e.g., “axe-the-tax discount”) than when it is just a regular discount (e.g., “customer rewards”). We conducted high-powered close replications of both original studies, Experiment 1 (N = 590) and Experiment 2 (N = 650), which reveal either no effect (Experiment 1: r = 0.02, 95% CI [−0.06, 0.10]) or a small effect (Experimental 2: r = 0.09, 95% CI [0.01, 0.16]) in the USA. We also replicated both experimental procedures in the UK to test whether the effect generalized to a value added tax system. Neither Experiment 1 (N = 595; r = 0.01, 95% CI [−0.07, 0.09]) nor Experiment 2 (N = 673; r = 0.03, 95% CI [−0.04, 0.11]) revealed an effect in the UK. Tax Aversion in hypothetical consumption decisions seems to be a smaller phenomenon than originally proposed and does not generalize to a value added tax system.

Despite being physically nonsalient and task-irrelevant, objects rendered in a color that once signaled monetary reward reflexively capture attention during visual search, a phenomenon known as value-driven attentional capture (VDAC). However, it remains a subject of empirical controversy whether learned reward associations are necessary to driving subsequent attentional capture: VDAC-like effects have been observed when accuracy-based feedback alone was used during the VDAC training phase, resulting in attentional capture by objects that were never associated with monetary reward; perplexingly, the presence of these VDAC-like effects in the literature conflicts with those of a number of control studies in which no such capture has been observed, leaving the issue currently unresolved. In this Registered Report, we present new empirical evidence of attentional capture by unrewarded former targets following limited accuracy-based training. We proposed to replicate these results in an independent sample and to test an empirically derived hypothesis concerning a methodological difference between the studies that have shown VDAC-like effects with accuracy-based feedback and those that have not. In short, we found no evidence that this methodological difference accounts for the inconsistencies in the literature, but our replication efforts were overwhelmingly successful, thus reinvigorating debate about the role that selection history may play in value-driven attentional capture.

In this article, we use an experimental survey design to explore how the tactical choices of social movements affect public opinion about whether the government should negotiate with the movement and the bargains that should be struck once negotiations begin. In doing so, we test competing theories about how we should expect the use of tactics with varying degrees of extremeness—including demonstrations, occupations, and bombings—to influence public opinion. We find that respondents are less likely to think the government should negotiate with organizations that use the tactic of bombing when compared with demonstrations or occupations. However, depending on the outcome variable and baseline category used in the analysis, we find mixed support for whether respondents think organizations that use bombings should receive less once negotiations begin. The results of this article are generally consistent with the theoretical and policy-based arguments centering around how governments should not negotiate with organizations that engage in violent activity commonly associated with terrorist organizations.

Can securities be settled on a blockchain, and, if so, what are the gains relative to existing settlement systems? The main benefit of a blockchain is faster and more flexible settlement, whereas settlement fails need to be ruled out where participants fork the chain to cancel trading losses. With a proof-of-work protocol, the blockchain needs to restrict settlement speed through block size and time in order to generate transaction fees, which finance costly mining. Despite mining being a deadweight cost, our estimates for the U.S. corporate debt market yield net gains from a blockchain in the range of 1–4 bps.Received May 31, 2017; editorial decision May 29, 2018 by Editor Itay Goldstein.

When encountering an unknown individual, social categorization of the individual has been shown to automatically proceed on the basis of three fundamental dimensions: People seem to mandatorily encode race, sex and age. In contradiction to this general finding, Kurzban et al. (2001) showed that race encoding is not automatic and inevitable, but rather a byproduct of categorization in terms of coalitions. In particular, they argue and empirically support that when other coalitional information is present, the encoding of race is spectacularly reduced. In the present contribution, we present a replication of the race-erased effect reported by Kurzban et al. First, we give a detailed overview of the hypotheses, the experimental methodology, the derivation of the sample size required to achieve a power of 95%, and the criteria that need to be met for a successful replication. Then we present the findings of an empirical test that met the requirements of our power analyses. Our results indicate that the encoding of race is indeed reduced when another coalitional cue is available, yet this reduction is less marked than in the original study. This experiment was preregistered before data collection at Open Science Framework, osf.io/vnhrm/.

Past research suggests that pathogen-avoidance motives (e.g., disgust sensitivity) relate to greater opposition to immigration. Two accounts have been proposed to explain this relationship, one of which emphasizes proximally avoiding outgroups, and the other of which emphasizes adherence to traditional norms. According to the former, immigrants are perceived as being more infectious because they carry novel pathogens due to their foreign ecological origins. According to the latter, immigrants' foreign norms are perceived as posing a pathogen threat. This study aimed to disentangle these accounts. Participants (N = 975) were randomly assigned to read a description of an immigrant who had high or low contact with locals and high or low assimilation to local norms. The effect of disgust sensitivity on sentiments toward the immigrant (and immigrants like him) was compared across conditions. Results supported the traditional norms account: disgust sensitivity related to anti-immigrant sentiments when the immigrant was described as not assimilating to local norms, but not when he was described as assimilating. Contrary to the outgroup avoidance account, the relationship between disgust sensitivity and anti-immigrant sentiments did not vary across the high-contact and low-contact conditions. Results suggest that resistance to foreign norms, rather than avoidance of novel pathogens, better explains the relationship between pathogen avoidance and outgroup prejudice.

. We replicated and extended a study by Spruyt and Hermans (2008) in which picture primes engendered an evaluative-priming effect on the pronunciation of target words. As preliminary steps, we assessed data reproducibility of the original study, conducted Pilot Study I to identify highly semantically related prime-target pairs, reanalyzed the original data excluding such pairs, conducted Pilot Study II to demonstrate that we can replicate traditional associative priming effects in the pronunciation task, and conducted Pilot Study III to generate relatively unrelated sets of prime pictures and target words. The main study comprised three between-participants conditions: (1) a close replication of the original study, (2) the same condition excluding highly related prime-target pairs, and (3) a condition based on the relatively unrelated sets of prime pictures and target words developed in Pilot Study III. There was little evidence for an evaluative priming effect independent of semantic relatedness.

Narcissism is a personality trait characterized by feelings of grandiosity, a craving for admiration, and a lack of empathy. Although there are reasons to expect that narcissism might have adverse physiological and health implications, very little research has directly assessed such claims. Moreover, prior research specifically assessing links between narcissism and basal levels of the stress hormone cortisol yields mixed evidence. In an attempt to reconcile previously inconsistent findings, we examined narcissism and basal cortisol in a sample of 366 young adults. We found little evidence for an association between narcissism and cortisol. We discuss how narcissism may be related to physiological outcomes over time and across situations.

Inductive learning takes place when people learn a new concept or category by observing a variety of exemplars. Kornell and Bjork (2008) asked participants to learn new painting styles either by presenting different paintings of the same artist consecutively (massed presentation) or by mixing paintings of different artists (spaced presentation). In their second experiment, Kornell and Bjork (2008) showed with a final style recognition test, that spacing resulted in better inductive learning than massing. Also, by using this style recognition test, they ruled out the possibility that spacing merely resulted in a better memory for the labels of the newly learned painting styles. The findings from Kornell and Bjork’s (2008) second experiment are important because they show that the benefit of spaced learning generalizes to complex learning tasks and outcomes, and that it is not confined to rote memory learning. However, the findings from Kornell and Bjork’s (2008) second experiment have never been replicated. In the present study we performed an exact and high-powered replication of Kornell and Bjork’s (2008) second experiment with a Web-based sample. Such a replication contributes to establish the reliability of the original finding and hence to more conclusive evidence of the spacing effect in inductive learning. The findings from the present replication attempt revealed a medium-sized advantage of spacing over massing in inductive learning, which was comparable to the original effect in the experiment by Kornell and Bjork (2008). Also, the 95% confidence intervals (CI) of the effect sizes from both experiments overlapped considerably. Hence, the findings from the present replication experiment and the original experiment clearly reinforce each other.

Marketplace lending relies on screening and information production by investors, a major deviation from the traditional banking paradigm. Theoretically, the participation of sophisticated investors improves screening outcomes and also creates adverse selection among investors. In maximizing loan volume, the platform trades off these two forces. As the platform develops, it optimally increases platform prescreening intensity but decreases information provision to investors. Using novel investor-level data, we find that sophisticated investors systematically outperform, and this outperformance shrinks when the platform reduces information provision to investors. Our findings shed light on the optimal distribution of information production in this new lending model.Received August 29, 2018; editorial decision July 1, 2018 by Editor Itay Goldstein.

In a widely cited paper, Jefferies et al. (2008) report a study in which they manipulated participants’ mood and examined the effects of this manipulation on their performance on the Attentional Blink task. Their results revealed an interaction between emotional valence and arousal: attentional control of participants who experienced a negative mood with low arousal (i.e. sadness) was best, whereas it was worst for participants who experienced a negative mood with high arousal (i.e. anxiety). Performance for participants who were in a positive mood, either with low arousal (i.e. calmness) or high arousal (i.e. happiness) had intermediate scores. In this study, I examined the replicability of this effect and performed additional analyses to investigate the extent to which this effect is due to perceptual or attentional processes and to examine the role of distraction on AB performance. Importantly, the results showed that the crucial interaction between emotional valence and arousal did not reach significance. This could be due a diversity of factors that are addressed in the discussion.

Evaluative conditioning (EC) is proposed as a mechanism of automatic preference acquisition in dual-process theories of attitudes (Gawronski, B., & Bodenhausen, G. V. (2006). Associative and propositional processes in evaluation: An integrative review of implicit and explicit attitude change. Psychological Bulletin, 132(5), 692–731. doi:10.1037/0033-2909.132.5.692). Evidence for the automaticity of EC comes from studies claiming EC effects for subliminally presented stimuli. An impression-formation study showed a selective influence of briefly presented primes on implicitly measured attitudes, whereas supraliminally presented behavioural information about the target person was reflected in explicit ratings (Rydell, R. J., McConnell, A. R., Mackie, D. M., & Strain, L. M. (2006). Of two minds forming and changing valence-inconsistent implicit and explicit attitudes. Psychological Science, 17(11), 954–958. doi:10.1111/j.1467-9280.2006.01811.x) This finding is considered one of the strongest pieces of evidence for dual process theories (Sweldens, S., Corneille, O., & Yzerbyt, V. (2014). The role of awareness in attitude formation through evaluative conditioning. Personality and Social Psychology Review, 18(2), 187–209. doi:10.1177/1088868314527832), and it is therefore crucial to assess its reliability and robustness. The present study presents two registered replications of the Rydell et al. (2006) study. In contrast to the original findings, the implicit measures did not reflect the valence of the subliminal primes in both studies.

An abundance of recent empirical data suggest that repeatedly allocating visual attention to task-relevant and/or reward-predicting features in the visual world engenders an attentional bias for these frequently attended stimuli, even when they become task irrelevant and no longer predict reward. In short, attentional selection in the past hinders voluntary control of attention in the present. But do such enduring attentional biases rely on a history of voluntary, goal-directed attentional selection, or can they be generated through involuntary, effortless attentional allocation? An abrupt visual onset triggers such a reflexive allocation of covert spatial attention to its location in the visual field, automatically modulating numerous aspects of visual perception. In this Registered Report, we asked whether a selection history that has been reflexively and involuntarily derived (i.e., through abrupt-onset cueing) also interferes with goal-directed attentional control, even in the complete absence of exogenous cues. To build spatially distinct histories of exogenous selection, we presented abrupt-onset cues twice as often at one of two task locations, and as expected, these cues reflexively modulated visual processing: task accuracy increased, and response times (RTs) decreased, when the cue appeared near the target’s location, relative to that of the distractor. Upon removal of these cues, however, we found no evidence that exogenous selection history modulated task performance: task accuracy and RTs at the previously most-cued and previously least-cued sides were statistically indistinguishable. Thus, unlike voluntarily directed attention, involuntary attentional allocation may not be sufficient to engender historically contingent selection biases.

Memory is modified through the act of retrieval. Although retrieving a target piece of information may strengthen the retrieved information itself, it may also serve to weaken retention of related information. This phenomenon, termed retrieval-induced forgetting, has garnered substantial interest for its implications as to why forgetting occurs. The present study attempted to replicate the seminal work by Anderson et al. (1994) on retrieval-induced forgetting, given the apparent sensitivity of the effect to certain deviations from the original paradigm developed to study the phenomenon. The study extends the conditions under which retrieval-induced forgetting has been examined by utilizing both a traditional college undergraduate sample (Experiment 1), along with a more diverse internet sample (Experiment 2). In addition, Experiment 3 details a replication attempt of retrieval-induced forgetting using Anderson and Spellman's (1995) independent cue procedure. Retrieval-induced forgetting was observed when using the traditional retrieval practice paradigm with undergraduate (Experiment 1) and internet (Experiment 2) samples, though the effect was not found when using the independent cue procedure (Experiment 3). Thus, the study can provide an indication as to the robustness of retrieval-induced forgetting to deviations from the traditional college undergraduate samples that have been used in the majority of existing research on the effect.

This paper studies whether, in the consumer credit market, peer-to-peer (P2P) lending platforms serve as substitutes for banks or instead as complements. I develop a conceptual framework and derive testable predictions to distinguish between these two possibilities. Using a regulatory change as an exogenous shock to bank credit supply, I find that P2P lending is a substitute for bank lending in terms of serving infra-marginal bank borrowers yet complements bank lending with respect to small loans. These results indicate that the credit expansion resulting from P2P lending likely occurs only among borrowers who already have access to bank credit.Received June 1, 2017; editorial decision September 15, 2018 by Editor Andrew Karolyi.

This study was a conceptual replication of Sutin and Terracciano (2016). Australian adults (8296 men; 9205 women) completed self-report measures of personality, weight, height, waist circumference, perception of weight, and satisfaction with weight. Consistent with findings from North America, conscientiousness was most important for adiposity (BMI and waist circumference) and actual-perceived body weight discrepancy. Moderator effects for sex (and age) were observed but did not replicate Sutin and Terracciano (2016). Neuroticism, agreeableness and conscientiousness were important for body weight satisfaction, with stronger associations observed among women. Our findings demonstrate that personality is important for the objective and subjective experience of body weight, but further investigation of moderators is warranted. Cross-cultural prospective studies of personality and body image are recommended.

People with higher IQ scores also tend to perform better on elementary cognitive-perceptual tasks, such as deciding quickly whether an arrow points to the left or the right Jensen (2006). The worst performance rule (WPR) finesses this relation by stating that the association between IQ and elementary-task performance is most pronounced when this performance is summarized by people’s slowest responses. Previous research has shown that the WPR can be accounted for in the Ratcliff diffusion model by assuming that the same ability parameter—drift rate—mediates performance in both elementary tasks and higher-level cognitive tasks. Here we aim to test four qualitative predictions concerning the WPR and its diffusion model explanation in terms of drift rate. In the first stage, the diffusion model was fit to data from 916 participants completing a perceptual two-choice task; crucially, the fitting happened after randomly shuffling the key variable, i.e., each participant’s score on a working memory capacity test. In the second stage, after all modeling decisions were made, the key variable was unshuffled and the adequacy of the predictions was evaluated by means of confirmatory Bayesian hypothesis tests. By temporarily withholding the mapping of the key predictor, we retain flexibility for proper modeling of the data (e.g., outlier exclusion) while preventing biases from unduly influencing the results. Our results provide evidence against the WPR and suggest that it may be less robust and less ubiquitous than is commonly believed.

Executing an important decision can be as easy as moving a mouse cursor or reaching towards the preferred option with a hand. But would we decide differently if choosing required walking a few steps towards an option? More generally, is our preference invariant to the means and motor costs of reporting it? Previous research demonstrated that asymmetric motor costs can nudge the decision-maker towards a less costly option. However, virtually all traditional decision-making theories predict that increasing motor costs symmetrically for all options should not affect choice in any way. This prediction is disputed by the theory of embodied cognition, which suggests that motor behavior is an integral part of cognitive processes, and that motor costs can affect our choices. In this registered report, we investigated whether varying motor costs can affect response dynamics and the final choices in an intertemporal choice task: choosing between a readily available small reward and a larger but delayed reward. Our study compared choices reported by moving a computer mouse cursor towards the preferred option with the choices executed via a more motor costly walking procedure. First, we investigated whether relative values of the intertemporal choice options affect walking trajectories in the same way as they affect mouse cursor dynamics. Second, we tested a hypothesis that, in the walking condition, increased motor costs of a preference reversal would decrease the number of changes-of-mind and therefore increase the proportion of impulsive, smaller-but-sooner choices. We confirmed the hypothesis that walking trajectories reflect covert dynamics of decision making, and rejected the hypothesis that increased motor costs of responding affect decisions in an intertemporal choice task. Overall, this study contributes to the empirical basis enabling the decision-making theories to address the complex interplay between cognitive and motor processes.

Blockchain technology provides decentralized consensus and potentially enlarges the contracting space through smart contracts. Meanwhile, generating decentralized consensus entails distributing information that necessarily alters the informational environment. We analyze how decentralization relates to consensus quality and how the quintessential features of blockchain remold the landscape of competition. Smart contracts can mitigate informational asymmetry and improve welfare and consumer surplus through enhanced entry and competition, yet distributing information during consensus generation may encourage greater collusion. In general, blockchains sustain market equilibria with a wider range of economic outcomes. We further discuss the implications for antitrust policies targeted at blockchain applications.Received May 31, 2017; editorial decision May 29, 2018 by Editor Itay Goldstein.

To enhance government accountability, reformers have advocated strengthening institutions of “horizontal accountability,” particularly auditing institutions that can punish lawbreaking elected officials. Yet, these institutions differ in their willingness to punish corrupt politicians, which is often attributed to variation in their degree of independence from the political branches. Taking advantage of a randomized natural experiment embedded in Brazil’s State Audit Courts, we study how variation in the appointment mechanisms for choosing auditors affects political accountability. We show that auditors appointed under few constraints by elected officials punish lawbreaking politicians—particularly co-partisans—at lower rates than bureaucrats insulated from political influence. In addition, we find that even when executives are heavily constrained in their appointment of auditors by meritocratic and professional requirements, auditors still exhibit a pro-politician bias in decision making. Our results suggest that removing bias requires a level of insulation from politics rare among institutions of horizontal accountability.

A key feature of the human cognitive system is its ability to deal with an ever-changing environment. One prototypical example is the observation that we adjust our information processing depending on the conflict-likelihood of a context (context-specific proportion congruency effect, CSPC, Crump etal., 2006). Recently, empirical studies started to question the role of consciousness in these strategic adaptation processes (for reviews, see Desender and Van den Bussche, 2012; Kunde etal., 2012). However, these studies have not yielded unequivocal results (e.g., Kunde, 2003; Heinemann etal., 2009; Van Gaal etal., 2010a; Desender etal., 2013; Reuss etal., 2014). In the present study, we aim at replicating the experiment of Heinemann etal. (2009) in which the proportion of congruent and incongruent trials between different contexts was varied in a masked priming task. Their results showed a reduction of the congruency effect for the context with more incongruent trials. However, this CSPC effect was only observed when the prime–target conflict was conscious, rather than unconscious, suggesting that context-specific control operates within the boundaries of awareness. Our replication attempt however contrasts these findings. In the first experiment we found no evidence for a CSPC effect in reaction times (RTs), neither in the conscious nor in the unconscious condition. The error rate analysis did show a CSPC effect, albeit not one modulated by consciousness. In the second experiment we found an overall CSPC effect in RTs, independent of consciousness. The error rates did not display a CSPC pattern. These mixed results seem to nuance the findings of Heinemann etal. (2009) and highlight the need for replication studies in psychology research.

We provide large-scale evidence on the occurrence and value of FinTech innovation. Using data on patent filings from 2003 to 2017, we apply machine learning to identify and classify innovations by their underlying technologies. We find that most FinTech innovations yield substantial value to innovators, with blockchain being particularly valuable. For the overall financial sector, internet of things (IoT), robo-advising, and blockchain are the most valuable innovation types. Innovations affect financial industries more negatively when they involve disruptive technologies from nonfinancial startups, but market leaders that invest heavily in their own innovation can avoid much of the negative value effect.ReceivedMay 31, 2017; editorial decision September 30, 2018 by Editor Andrew Karolyi.
