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]
Intelligence testing has long been an important branch of quantitative psychology. The nineteenth-century English statistician Francis Galton, a pioneer in psychometrics, was the first to create a standardized test of intelligence, and he was among the first to apply statistical methods to the study of human differences and their inheritance.
The term sample of behavior refers to an individual's performance on tasks that have usually been prescribed beforehand. For example, a spelling test for middle school students cannot include all the words in the vocabularies of middle schoolers because there are thousands of words in their lexicon; a middle school spelling test must include ...
Psychophysics quantitatively investigates the relationship between physical stimuli and the sensations and perceptions they produce. Psychophysics has been described as "the scientific study of the relation between stimulus and sensation" [1] or, more completely, as "the analysis of perceptual processes by studying the effect on a subject's experience or behaviour of systematically varying the ...
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 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.
Transient attention is a short-term response to a stimulus that temporarily attracts or distracts attention. Researchers disagree on the exact amount of the human transient attention span, whereas selective sustained attention, also known as focused attention, is the level of attention that produces consistent results on a task over time.
The measurement of memory in its various types has always been the favorite subject of psychologists. According to them remembering involves those processes which are essential for memory. Basically, there appears to be three different memory systems. Sensory information storage; Short-term memory; Long-term memory
