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.
An operational definition specifies concrete, replicable procedures designed to represent a construct. In the words of American psychologist S.S. Stevens (1935), "An operation is the performance which we execute in order to make known a concept."
The authors emphasized that the findings reflect a problem that affects all of science and not just psychology, and that there is room to improve reproducibility in psychology. In 2021, the project showed that of 193 experiments from 53 top papers about cancer published between 2010 and 2012, only 50 experiments from 23 papers could be replicated.
Since different definitions of "effect size" capture different ways for X and Y to be dependent, there are many different definitions of effect size. In practice, effect sizes cannot be directly observed, but must be measured by statistical estimators. For example, the above definition of effect size is often measured by Cohen's d estimator
The term 'steering cognition' was coined by the researcher Simon P. Walker who discovered consistent, replicable patterns of attention and corresponding response through repeated cognitive tests between 2000 and 2015, in studies with over 15,000 individuals. [1]
The 'doorway effect' or 'location updating effect' is a replicable psychological phenomenon characterized by short-term memory loss when passing through a doorway or moving from one location to another. [1]

A true score is the replicable feature of the concept being measured. It is the part of the observed score that would recur across different measurement occasions in ...
