Contrary to previous findings in other fields, this study found that the majority of replications in psychology journals reported similar findings to their original studies (i.e., they were successful replications). However, replications were significantly less likely to be successful when there was...
In 2015, a group of 271 researchers published the results of their five-year effort to replicate 100 different experimental studies previously published in three top psychology journals.4The replicators worked closely with the original researchers of each study in order to replicate the experiments as...
In modern times, the science of psychology is facing a crisis. It turns out that many studies in psychology—including many highly cited studies—do not replicate. In an era where news is instantaneous, the failure to replicate research raises important questions about the scientific process in g...
beliefs. We also found no evidence that personal investment or lack of expertise discouraged belief updating, but people higher on intellectual humility updated their beliefs slightly more. Overall, our results suggest that replication studies can contribute to self-correction within psychology, but ...
In the current paper the frequency of negative responses to replications in psychology, and the attention such responses attract, was measured in a series of three studies. Study 1 indicates that replications do not attract more negative mentions in literature than randomly selected non-replication ...
The second chapter discusses the replicability crisis in psychology with an analysis of the origins, the factors that contributed to the crisis and solutions proposed for a change of direction. The third chapter analyzes the role of Type M and Type S errors in the replicability crisis. Studies ...
During the test phase, participants are once more exposed to the CS, again in the absence of the US, and CRs are measured. Based on this paradigm, studies have reported that even after a complete reduction of CRs over the course of extinction, CRs often return during the test phase (“...
the statistical power to detect the expected effect size (ES) of the typical study, is low or very low. The low power in most studies undermines the use of NHST to study phenomena with moderate or low ESs. We conclude by providing some suggestions on how to increase the statistical power...
Theproject, spearheaded by the Open Science Collaboration, aimed to replicate 100 studies published in three high-profile psychology journals during 2008. The idea arose amid a growing concern that psychology has afalse-positive problem: In recent years, important findings in the field have been cal...
Criteria of the peer review process for publication of experimental and quasi-experimental research in Psychology: A guide for creating research papers Experimental research in Psychology is characterized by ensuring a method that guarantees objectivity, reliability, validity and replication of results.
