Describes the establishment of a psychological space for any set of stimuli by determining metric distances between the stimuli with the probability that a response learned for a stimulus will generalize to the other. (Author/TW)

Findings indicate substantial effects on verbal reports of pain, avoidance behaviour, psychophysiological indices, power function parameters, and sensory decision theory indices. Discussion centers on how social models…
