Abstract
The effects of responses of another person or a computer occurring prior to the subjects' responses in tasks of recognition of auditory intensity were interpreted in terms of a signal-detection model which assumed that subjects shifted their decision criteria temporarily on each trial. A parameter representing the amount of criterion shift reliably estimated sensitivity to social influence. When the social sensitivity parameter was estimated from the data, discriminative ability, defined as d', was unaffected by the presence of social influence. Principal components analyses suggested that social sensitivity and discriminative ability represented essentially orthogonal components of subjects' decision behavior.Keywords
