A Signal Detection Approach to the Study of Set in Tachistoscopic Recognition

Abstract

TSD techniques were used to evaluate the effect of the “set” variable on tachistoscopic recognition. Ss made judgments about the presence or absence of “set” words and control words in a background of visual noise. The resultant ROC curves showed an influence of perceptual sensitivity but no effect of response bias. The d' values for the set words were found to be significantly larger than those for the control words.
