In psychological science, replicability—repeating a study with a new sample achieving consistent results (Parsons et al., 2022)—is critical for affirming the validity of scientific findings. Despite its importance, replication efforts are few and far between in psychological science with many attempts failing to corroborate past findings. This scarcity, compounded by the difficulty in accessing replication data, jeopardizes the efficient allocation of research resources and impedes scientific advancement. Addressing this crucial gap, we present the Replication Database (https://forrt-replications.shinyapps.io/fred_explorer), a novel platform hosting 1,239 original findings paired with replication findings. The infrastructure of this database allows researchers to submit, access, and engage with replication findings. The database makes replications visible, easily findable via a graphical user interface, and tracks replication rates across various factors, such as publication year or journal. This will facilitate future efforts to evaluate the robustness of psychological research.

IntroductionExtant research has studied prejudice expressions mainly from the majority perspective. We examined whether prejudice expressions conceptualized as subtle (vs. blatant) are perceived differently by their targets.MethodsParticipants who self-identified as potential targets of ethno-racial or religious prejudice (e.g., anti-Muslim, anti-Asian, anti-Arab, anti-Slavic, and anti-Black prejudice), answered questions about verbal expressions of prejudice taken from the subtle and blatant prejudice scales in an online survey.ResultsItems of the subtle (vs. blatant) prejudice scale were rated as more socially accepted and less discriminatory, elicited less negative emotions, and were reported to be experienced more often. Subtle expressions of prejudice were not more familiar to participants than blatant ones. Remarkably, blatant prejudice expressions were also perceived as relatively socially accepted and subtle prejudices as relatively discriminatory, as indicated by mean ratings above the scale midpoint. Lower discrimination ratings of subtle (vs. blatant) prejudice expressions were mainly due to perceptions of expressions exaggerating cultural differences. Exploratory analyses indicate that participants who reported more (vs. less) frequent overall exposure to the prejudice expressions perceived subtle and blatant stimuli as similarly discriminatory. This finding is compatible with the idea that individuals factor their personal experiences with prejudice into their assessments of discrimination.DiscussionWe discuss implications for interventions, especially regarding the social acceptability of blatant prejudice and promoting awareness of the discriminatory impact of subtle prejudice.

The Effort-Expenditure for Rewards Task (EEfRT) has gained validity evidence from several studies. However, various modifications have been applied to the original version, which have never been compared systematically. In Study 1, we tested 120 healthy participants to directly compare two versions of the EEfRT. In Study 2, we tested a larger sample of 394 healthy participants to further examine the original EEfRT. We replicated the split-half reliability of both task versions. However, self-reported personality traits (e.g., trait BAS) correlated with only some task performance parameters in Study 1, which did not replicate for the original EEfRT in Study 2. Our results indicate complex and sometimes inconsistent relations between different personality traits, task properties, and reward attributes.

During government-implemented restrictions in the wake of the COVID-19 pandemic, people's everyday lives changed profoundly. However, there is to date little research chronicling how people perceived their changed everyday lives and which consequences this had. In a two-wave study, we examined the psychological characteristics of people's situations and their correlates during shutdown in a large German sample (NT1 = 1,353; NT2 = 446). First, we compared characteristics during government-issued restrictions with retrospective accounts from before and with a follow-up assessment 6 to 7 months later when many restrictions had been lifted. We found that mean levels were lower and variances were higher for most characteristics during the shutdown. Second, the experience of certain situation characteristics was associated in meaningful and theoretically expected ways with people's traits, appraisals of the COVID-19 crisis, and subjective well-being. Lastly, situation characteristics often substantially explained the associations of traits with appraisals and well-being. Our findings highlight the importance of considering perceived situations as these contribute to people's functioning during crises.

Dopamine (DA) is known to be involved in various aspects of reward processing and goal-directed behavior. The present preregistered study aims at directly accessing the causal influence of DA activity on reward motivation in humans, while also accounting for trait extraversion. Therefore, we examined the effect of a single dose of the DA D2 receptor antagonist sulpiride (200 mg) on effort allocation in a modified version of the Effort-Expenditure for Reward Task (EEfRT). Based on its presumably DA increasing action, we expected the low dose of sulpiride to increase participants’ willingness to allocate effort during the modified EEfRT relative to placebo, especially in trials with low probability of reward attainment. Further, we expected a moderating effect of trait extraversion on the effects of sulpiride. Two hundred and three healthy male participants were tested in a randomized, double-blind between-subjects design. Contrary to our expectations, sulpiride reduced the average number of clicks within the modified EEfRT and did not interact with reward attributes, suggesting a more global and not reward-specific effect of sulpiride. Furthermore, trait extraversion did not moderate the effect of sulpiride. Our results provide initial support for the validity of the modified version of the EEfRT, suggesting a possible inhibiting effect of a low dose of sulpiride on approach motivation regardless of trait extraversion. However, given the mixed pattern of findings and the possible confounding role of motoric abilities, further studies examining these effects are clearly warranted.
