Synonyms: PSMT, picture set test
Experimental conditions are the subsets of an experiment that define the relevant experimental manipulation.
In the Cognitive Atlas, we define a contrast as any function over experimental conditions. The simplest contrast is the indicator value for a specific condition; more complex contrasts include linear or nonlinear functions of the indicator across different experimental conditions.
An indicator is a specific quantitative or qualitative variable that is recorded for analysis. These may include behavioral variables (such as response time, accuracy, or other measures of performance) or physiological variables (including genetics, psychophysiology, or brain imaging data).
Definition contributed by CTorgerson about five years ago:The Picture Sequence Memory Test involves recalling increasingly lengthy series of illustrated objects and activities that are presented in a particular order on the computer screen, with corresponding audiorecorded phrases played. The participants are asked to recall the sequence of pictures demonstrated over two learning trials; sequence length varies from 6-18 pictures, depending on age. Participants are given credit for each adjacent pair of pictures they correctly place (i.e., if pictures in locations 7 and 8 are placed in that order and adjacent to each other anywhere, such as slots 1 and 2, one point is awarded), up to the maximum value for the sequence, which is one less than the sequence length. (That is, if 18 pictures are in the sequence, the maximum score is 17 – the number of adjacent pairs of pictures that exist).REVISION 2
