Memory retrieval and central comparison times in information processing.

Abstract

Varied memory load and display load orthogonally in a simple information-reduction task which required S to respond either yes or no that a visual display did or did not contain an item previously memorized. 12 Ss were given extended (12 days) practice. RT was a linear function of memory load, and the slope constants of that relationship were a linear function of display load for positive responses and a power function of display load for negative responses. The fitted equations provided indexes of memory retrieval time and central comparison time separately. These times decreased systematically with practice. It was concluded that throughout S performed an exhaustive serial comparison process with display rechecking prior to a negative response. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
