Ideal partner preferences (i.e., ratings of the desirability of attributes like attractiveness or intelligence) are the source of numerous foundational findings in the interdisciplinary literature on human mating. Recently, research on the predictive validity of ideal partner preference matching (i.e., Do people positively evaluate partners who mat...

Background: The Psychological Science Accelerator (PSA) recently completed a large-scale moral psychology study using translated versions of the Oxford Utilitarianism Scale (OUS). However, the translated versions have no validity evidence. Objective: The study investigated the structural validity evidence of the OUS across 15 translated versions an...
Abstract This paper presents a generalized registration form for systematic reviews that can be used when currently available forms are not adequate. The form is designed to be applicable across disciplines (i.e., psychology, economics, law, physics, or any other field) and across review types (i.e., scoping review, review of qualitative studies, m...
The past decade has witnessed a proliferation of big team science (BTS), endeavours where a comparatively large number of researchers pool their intellectual and/or material resources in pursuit of a common goal. Despite this burgeoning interest, there exists little guidance on how to create, manage and participate in these collaborations. In this...
Following theories of emotional embodiment, the facial feedback hypothesis suggests that individuals’ subjective experiences of emotion are influenced by their facial expressions. However, evidence for this hypothesis has been mixed. We thus formed a global adversarial collaboration and carried out a preregistered, multicentre study designed to spe...
Progress in psychology has been frustrated by challenges concerning replicability, generalizability, strategy selection, inferential reproducibility, and computational reproducibility. Although often discussed separately, these five challenges may share a common cause: insufficient investment of intellectual and nonintellectual resources into the t...
The facial feedback hypothesis suggests that an individual's facial expressions can influence their emotional experience (e.g., that smiling can make one feel happier). However, a reoccurring concern is that supposed facial feedback effects are merely methodological artifacts. Six experiments conducted across 29 countries (N = 995) examined the ext...
The facial feedback hypothesis suggests that an individual’s facial expressions can influence their emotional experience (e.g., that smiling can make one feel happier). However, a reoccurring concern is that demand characteristics drive this effect. Across three experiments (n = 250, 192, 131), university students in the United States and Kenya pos...
This Systematic Review Registration Form is intended as a general-purpose registration form. The form is designed to be applicable to reviews across disciplines (i.e., psychology, economics, law, physics, or any other field) and across review types (i.e., scoping review, review of qualitative studies, meta-analysis, or any other type of review). Th...
Ongoing technological developments have made it easier than ever before for scientists to share their data, materials, and analysis code. Sharing data and analysis code makes it easier for other researchers to reuse or check published research. However, these benefits will emerge only if researchers can reproduce the analyses reported in published...
Progress in psychology has been frustrated by challenges concerning replicability, generalizability, strategy selection, inferential reproducibility, and computational reproducibility. Although often discussed separately, we argue that these five problems share a common cause: insufficient investment of resources into the typical psychology study....
The COVID-19 pandemic presents a critical need to identify best practices for communicating health information to the global public. It also provides an opportunity to test theories about risk communication. As part of a larger Psychological Science Accelerator COVID-19 Rapid Project, a global consortium of researchers will experimentally test comp...
The Psychological Science Accelerator's Rapid-Response COVID-19 Project (PSACR) is a project to rapidly select and conduct rigorous, multi-site, and multinational research to understand the psychological and behavioral aspects of the COVID-19 crisis. Here we describe the process we used to select our projects and our general methods for implementin...
The facial feedback hypothesis suggests that an individual’s subjective experience of emotion is influenced by their facial expressions. Researchers, however, currently face conflicting narratives about whether this hypothesis is valid. A large replication effort consistently failed to replicate a seminal demonstration of the facial feedback hypoth...
Over the last ten years, Oosterhof and Todorov’s valence-dominance model has emerged as the most prominent account of how people evaluate faces on social dimensions. In this model, two dimensions (valence and dominance) underpin social judgments of faces. Because this model has primarily been developed and tested in Western regions, it is unclear w...
Researchers have proposed that blocking facial feedback via glabellar-region botulinum toxin injections (GBTX) can reduce depression. Random-effects meta-analyses of studies that administered GBTX to individuals with depression indicate that, 6 weeks postintervention, GBTX groups were significantly less depressed compared to placebo groups ( d = 0....
Ongoing technological developments have made it easier than ever before for scientists to share their data, materials, and analysis code. Sharing data and analysis code makes it easier for other researchers to re-use or check published research. These benefits will only emerge if researchers can reproduce the analysis reported in published articles...
The facial feedback hypothesis suggests that an individual’s experience of emotion is influenced by feedback from their facial movements. To evaluate the cumulative evidence for this hypothesis, we conducted a meta-analysis on 286 effect sizes derived from 138 studies that manipulated facial feedback and collected emotion self-reports. Using random...
The facial feedback hypothesis suggests that an individual’s subjective experience of emotion is influenced by their own facial expressions. However, researchers currently face conflicting narratives about whether this hypothesis is valid. A large collaborative effort consistently failed to replicate a seminal demonstration of the facial feedback h...
Mental simulation theories of language comprehension propose that people automatically create mental representations of real objects. Evidence from sentence-picture verification tasks has shown that people mentally represent various visual properties such as shape, color, and size. However, the evidence for mental simulations of object orientation...
Concerns about the veracity of psychological research have been growing. Many findings in psychological science are based on studies with insufficient statistical power and nonrepresentative samples, or may otherwise be limited to specific, ungeneralizable settings or populations. Crowdsourced research, a type of large-scale collaboration in which...
The debate about whether replication studies should become mainstream is essentially driven by disagreements about their costs and benefits and the best ways to allocate limited resources. Determining when replications are worthwhile requires quantifying their expected utility. We argue that a formalized framework for such evaluations can be useful...
Testicular self-examination (TSE) promotional interventions historically operate without a theoretical framework, which negatively influences their effectiveness. As TSE is critical to the early detection of testicular cancer, this behavior is an essential component to improving overall male well-being. To address this need, the Control Identity pe...
Approach:
This article summarizes findings from portions of data collected in a larger qualitative study conducted at a new medical school in the United States that utilizes diverse pedagogies and experiences to develop student knowledge, clinical skills, attitudes, and dispositions. Primary data sources included focus groups and individual interv...
In a summary of recent discussions about the role of direct replications in psychological science, Zwaan, Etz, Lucas, and Donnellan (2017; henceforth ZELD) argue that replications should be more mainstream, and discuss six common objections to direct replication studies. We believe that the debate about the importance of replication research is ess...

Experience sampling data reveal that people can experience mixed emotions (i.e., the co-occurrence of positive and negative affect) in daily life and that some pairs of opposite-valence emotions co-occur more often than others. Both experience sampling and laboratory data suggest that, not surprisingly, people often experience mixed emotions when d...
To achieve high levels of Subjective Well Being, it is argued that one must experience frequent positive affect, low levels of negative affect, and high satisfaction with life. However, researchers have not investigated whether the lay theories of happiness also include these dimensions. Using a 2 (negative, positive affectivity) x 2 (low, high lif...

I am conducting a meta-analytic review on the effects of botulinum toxin on emotional outcomes. I am seeking any unpublished studies, data sets, or “in press” papers that include individuals who have received botulinum toxin treatments (i.e., Botox) and measures of emotion (e.g., depression, positive affect, sadness). If you have any unpublished data, or if you have questions/comments, please let me know by February 8th.
How can meta-analysts assess and test the effects of publication bias in meta-analysis with robust variance estimates (RVE)?
From what I have been told, there has not been a lot of theoretical work examining how to create funnel plots and models that adjust for publication bias (such as PET-PEESE) using RVE methods. Is it reasonable to use these tools to assess and test the effects of publication bias, but with the caveat that it’s less than ideal?
Dear Researchers,
Is there any evidence for typicality effects in memory retrieval? For example, if I ask you to recall an example of a fruit you have eaten, would you be more likely to retrieve a memory of eating an apple (a more typical fruit) compared to a fig (a less typical fruit)?
I have seen this demonstrated in categorization tasks, but I am not familiar with any research on this in the context of memory.
I am conducting a meta-analysis on the effect of facial feedback on emotional experience. I am seeking any unpublished studies, data sets, or “in press” papers that include a manipulation of facial posture (including facial posing, facial expression suppression, and Botox treatment) and self-reported emotional experience.
Please let me know by December 1st whether you have unpublished data you want to share.
