Abstract

Whereas knowledge of results (KR), that knowledge received on the outcome of one's responses, has been shown to facilitate learning of visual search in inspection, further research is required to determine its influence upon decision-making, the other aspect of inspection. Twenty subjects, randomly assigned to either a KR or No-KR group, performed a visual inspection task; defect probability and discriminability were manipulated within subjects, and sequence of discriminability levels was manipulated between subjects. Via a signal detection model interpretation, KR increased sensitivity but had mixed effects on response criterion. The sensitivity changes were interpreted via attention theory, and a cognitive model of KR utilization was presented.
