No Evidence that Continuous Affect Ratings Offer a Meaningful Measure of Affective Inertia Open
Affective inertia – the extent to which changes in one’s affective state persist over time – isan important feature of affect dynamics. It is often examined using experience sampling studies thatcapture momentary affect multiple times per …

Accuracy in Parameter Estimation and Simulation Approaches for Sample Size Planning with Multiple Stimuli Open
The planning of sample size for research studies often focuses on obtaining a significant result given a specified level of power, significance, and an anticipated effect size. This planning requires prior knowledge of the study design and…
The probabilistic and dynamic nature of perception in human generalization behavior Open
Generalization theories traditionally overlook how our mental representations dynamically change in the process of transferring learned knowledge to new contexts. We integrated perceptual and generalization theories into a computational mo…

VALID: A Checklist-Based Approach for Improving Validity in Psychological Research Open
In response to the replication and confidence crisis across various empirical disciplines, ensuring the validity of research has gained attention. High validity is crucial for obtaining replicable and robust study outcomes when both explor…
Remembering Affect Between Moments: Assessing Peak-End Effects In Continuous Affect Measures Open
In experience sampling studies, participants are intermittently measured with repeatedassessments, to track momentary affect changes. The data is collected in specific timeintervals, leaving information gaps between assessments. To capture…
Representational shifts as a distinct mechanism in associative learning and generalization Open
The peak shift effect in generalization, a robust phenomenon where the maximal response occurs to stimuli shifted away from the conditioned stimulus in the direction opposite the inhibitory stimulus, has been predominantly attributed to as…
Measuring Continuous Affect in Daily Life With Intensity Profile Drawings Open
We examined continuous affect drawings as innovative measure of affective experiences over time. Intensive longitudinal data often rely on discrete assessments, containing “blind spots” between measurements. With continuous affect drawings…

Subjective evidence evaluation survey for many-analysts studies Open
Many-analysts studies explore how well an empirical claim withstands plausible alternative analyses of the same dataset by multiple, independent analysis teams. Conclusions from these studies typically rely on a single outcome metric (e.g.…

The Replication Database: Documenting the Replicability of Psychological Science Open
In psychological science, replicability—repeating a study with a new sampleachieving consistent results (Parsons et al., 2022)—is critical for affirming the validity of scientific findings. Despite its importance, replication efforts are f…

The assessment of gender differences in perceptual fear generalization and related processes Open
In this study we aimed to investigate gender differences in fear generalization tendencies in humans and, inspired by recent findings in animal research, examine whether any such differences could stem from differences in memory precision.…

No harmful effect of propranolol administered prior to fear memory extinction in rats and humans Open
Exposure therapy is an evidence-based treatment option for anxiety-related disorders, but benzodiazepines have been reported to undermine its effects. This aligns with observations in the laboratory, where these anxiolytics were shown to i…
Data sharing upon request and statistical consistency errors in psychology: A replication of Wicherts, Bakker and Molenaar (2011) Open
Sharing research data allows the scientific community to verify and build upon published work. However, data sharing is not common practice yet. The reasons for not sharing data are myriad: Some are practical, others are more fear-related.…
Multiple pathways to widespread fears: Disentangling idiosyncratic fear generalization mechanisms using computational modeling Open
Human generalization research aims to understand the processes underlying the transfer of prior experiences to new contexts. Generalization research predominantly relies on descriptive statistics, assumes a single generalization mechanism,…
Multiverse analyses in the classroom Open
Most empirical papers in psychology involve statistical analyses performed on a new or existing dataset. Sometimes the robustness of a finding is demonstrated via data-analytical triangulation (e.g., obtaining comparable outcomes across di…
Severity and Crises in Science: Are We Getting It Right When We're Right and Wrong When We're Wrong? Open
Just as teachers give students exams to assess their mastery of a subject, researchers submit their theories to empirical tests. And just as a high score on a test by itself is not sufficient to believe in the student’s mastery of a subjec…
A review of applications of the Bayes factor in psychological research. Open
The last 25 years have shown a steady increase in attention for the Bayes factor as a tool for hypothesis evaluation and model selection. The present review highlights the potential of the Bayes factor in psychological research. We discuss…
A pre-registered, multi-lab non-replication of the action-sentence compatibility effect (ACE) Open
The Action-sentence Compatibility Effect (ACE) is a well-known demonstration of the role of motor activity in the comprehension of language. Participants are asked to make sensibility judgments on sentences by producing movements toward th…
Comparing dream to reality: an assessment of adherence of the first generation of preregistered studies Open
Preregistration is a method to increase research transparency by documenting research decisions on a public, third-party repository prior to any influence by data. It is becoming increasingly popular in all subfields of psychology and beyo…
