Psychologists must be able to test both for the presence of an effect and for the absence of an effect. In addition to testing against zero, researchers can use the two one-sided tests (TOST) procedure to test for equivalence and reject the presence …

Scientists should be able to provide support for the absence of a meaningful effect. Currently, researchers often incorrectly conclude an effect is absent based a nonsignificant result. A widely recommended approach within a frequentist framework is …

In theory, a comparison of two experimental effects requires a statistical test on their difference. In practice, this comparison is often based on an incorrect procedure involving two separate tests in which researchers conclude that effects differ …

Scientists, being human, make mistakes. We transcribe things incorrectly, we make errors in our code, and we intend to do things and then forget. The consequences of errors in research may be as minor as wasted time and annoyance, but may be as …

Since its beginnings in the 1940s, automated reasoning by computers has become a tool of ever growing importance in scientific research.So far, the rules underlying automated reasoning have mainly beenformulated by humans, in the form of program …

Psychological science is navigating an unprecedented period of introspection about the credibility and utility of its research. A number of reform initiatives aimed at increasing adoption of transparency and reproducibility-related research practices …

Reproducibility is a defining feature of science, but the extent to which it characterizes current research is unknown. We conducted replications of 100 experimental and correlational studies published in three psychology journals using high-powered …

This student project involved creating likelihood functions for the Bayesian estimation of cognitive parameters behind choices and response times in R, for the R package EMC2 of the Amsterdam Mathematical Psychology Lab. Particularly, the likelihood …

Beginning in 2011, public scandals and high-visibility critiques of research methods in psychology fed a broader “replication crisis”: foundational experiments could not be replicated, and statistical methods in social psychology demonstrated …

The MIT Press is thrilled to announce a groundbreaking partnership with the European Sociological Association (ESA), marking a significant step forward in the world of academic open access publishing. We are proud to welcome European Societies and …
