Brian Nosek of University of Virginia and colleagues sought out to replicate 100 different studies, all published in 2008. [5] The project pulled these studies from three different journals, Psychological Science, the Journal of Personality and Social Psychology, and the Journal of Experimental Psychology: Learning, Memory, and Cognition, published in 2008 to see if they could get the same ...
Although the concept has only appeared in the 2010s, replication studies have been existing for decades but were not acknowledged as such. [78] The 2019 report of the National academies include a meta-analysis of 25 replications published between 1986 and 2019.
Color reproduction is an aspect of color science concerned with producing light spectra that evoke a desired color, either through additive (light emitting) or subtractive (surface color) models. It converts physical correlates of color perception ( CIE 1931 XYZ color space tristimulus values and related quantities) into light spectra that can ...
Study replication rates were 23% for the Journal of Personality and Social Psychology, 48% for Journal of Experimental Psychology: Learning, Memory, and Cognition, and 38% for Psychological Science. Studies in the field of cognitive psychology had a higher replication rate (50%) than studies in the field of social psychology (25%). [77]
Replication using an independent cohort is required to rule out false positives identified in the initial study. This can be done in a human cohort or in a more focused manner in animal models. It is important that, when selecting the replication cohort, the individuals are reflective of the initial cohort and that the same confounding ...
All the 150 color drawings of interlocking patterns that he produced from 1937 to 1941 are reproduced in the book. It is, of course, the most essential part of the volume." [ 1 ] Marjorie Senechal wrote the entry for Mathematical Reviews : "The development of Escher's ideas is carefully traced, the influence of his work on others, and vice ...
The study included 150 Black children from segregated, nursery schools in Washington, D.C. with 50% of the participants being girls and 50% boys. There were 50 three-year-old, 50 four-year-old, and 50 five-year-old children in the study.
Reproducibility, closely related to replicability and repeatability, is a major principle underpinning the scientific method.For the findings of a study to be reproducible means that results obtained by an experiment or an observational study or in a statistical analysis of a data set should be achieved again with a high degree of reliability when the study is replicated.
