Stimulus and response frequency and sequential effects in memory scanning reaction times.

Abstract
Varied target set size, stimulus frequency, and response-stimulus interval in a design 1st used by S. Sternberg (1969). Ss were 48 undergraduates in an introductory psychology course. Significant effects on reaction time (RT) were found due to stimulus frequency, stimulus sequence, response frequency, response sequence, and the interaction between stimulus frequency and target set size. Response-stimulus interval affected only the RT intercept. The data are difficult to account for by assuming a serial exhaustive memory scanning process, but can easily be accounted for using a self-terminating scanning process.
