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 ...
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.
[2] Example of direct replication and conceptual replication. There are two main types of replication in statistics. First, there is a type called “exact replication” (also called "direct replication"), which involves repeating the study as closely as possible to the original to see whether the original results can be precisely reproduced. [3]
Focus on the replication crisis has led to renewed efforts in psychology to retest important findings. [41] [179] A 2013 special edition of the journal Social Psychology focused on replication studies. [13] Standardization as well as (requiring) transparency of the used statistical and experimental methods have been proposed. [180]
A replication attempt with a sample from a more diverse population, over 10 times larger than the original study, showed only half the effect of the original study. The replication suggested that economic background, rather than willpower, explained the other half. [6] [7] The predictive power of the marshmallow test was challenged in a 2020 study.
The effects of this can be seen in the ongoing replication crisis, hoaxes, and widespread outrage over the inefficacy of the current system. [147] [142] It's common to think that more oversight is the answer, as peer reviewers are not at all lacking in skepticism. But the issue is not the skepticism shared by the select few who determine ...
Cognitive imitation is a form of social learning, and a subtype of imitation.Cognitive imitation is contrasted with motor and vocal or oral imitation. As with all forms of imitation, cognitive imitation involves learning and copying specific rules or responses done by another.
A partial replication of the experiment was staged by British illusionist Derren Brown and broadcast on UK's Channel 4 in The Heist (2006). [42] Another partial replication of the experiment was conducted by Jerry M. Burger in 2006 and broadcast on the Primetime series Basic Instincts. Burger noted that "current standards for the ethical ...
