The use of mental chronometry in psychological research is far ranging, encompassing nomothetic models of information processing in the human auditory and visual systems, as well as differential psychology topics such as the role of individual differences in RT in human cognitive ability, aging, and a variety of clinical and psychiatric ...
The Cattell–Horn–Carroll theory factors that this test examines are based on 9 broad stratum abilities, although the test is able to produce 20 scores [4] only seven of these broad abilities are more commonly measured: comprehension-knowledge (Gc), fluid reasoning (Gf), short-term memory (Gsm), processing speed (Gs), auditory processing (Ga), visual-spatial ability (Gv), and long-term ...
Cognitive disengagement syndrome (CDS) is a syndrome characterized by developmentally inappropriate, impairing, and persistent levels of decoupled attentional processing from the ongoing external context and resultant hypoactivity.
The effect has been used to create a psychological test (the Stroop test) that is widely used in clinical practice and investigation. [ 1 ] A basic task that demonstrates this effect occurs when there is a mismatch between the name of a color (e.g., "blue", "green", or "red") and the color it is printed in (i.e., the word "red" printed in blue ...
Throughout its history, this test has been revised multiple times since its creation, starting with the WAIS in 1955, to the WAIS-R in 1981, to the WAIS-III in 1996, and most recently the WAIS-IV in 2008. This test helps assess the level of the individuals verbal comprehension, perceptual reasoning, working memory, and processing speed. [11]
One is the processing speed theory of cognitive aging by Tim Salthouse. [67] Drawing on the finding that cognitive processes generally slow as people grow older, Salthouse argues that slower processing leaves more time for working memory content to decay, thus reducing effective capacity.

The participant's objective for this test is to connect the circles in order, alternating between number and letter (e.g. 1-A-2-B) from start to finish. [43] The participant is required not to lift their pencil from the page. The task is also timed as a means of assessing speed of processing. [44]
