The mere-measurement effect is a phenomenon used in behavioural psychology. It explains that merely measuring or questioning an individual's intentions or anticipated regret [1] changes his or her subsequent behavior. The mere-measurement effect has been demonstrated in multiple behavioural contexts both general and specific.
Measurement in psychology and physics are in no sense different. Physicists can measure when they can find the operations by which they may meet the necessary criteria; psychologists have to do the same. They need not worry about the mysterious differences between the meaning of measurement in the two sciences (Reese, 1943, p. 49). [9]
Psychometrics deals with measurement of psychological attributes. It involves developing and applying statistical models for mental measurements. [2] The measurement theories are divided into two major areas: (1) Classical test theory; (2) Item Response Theory. [3]
The book discusses the extent to which psychology can measure mental attributes such as intelligence and examines the philosophical issues that arise from such attempts. The book examines three major models within psychometrics; classical test theory/true scores, latent variables/item response theory and representational measurement theory ...

When the foretasted event did not happen, Festinger and his associates observed how the attitudes of the group members changed. They published their results in a 1956 book called When Prophecy Fails. David Rosenhan in 1973 published a journal that involved research by participant observations. [11] see: on being sane in insane places.

In statistics, an effect size is a value measuring the strength of the relationship between two variables in a population, or a sample-based estimate of that quantity. It can refer to the value of a statistic calculated from a sample of data, the value of one parameter for a hypothetical population, or to the equation that operationalizes how statistics or parameters lead to the effect size ...
