Сognitive Style Differences in Detection and Discrimination of Sensory Signals

A. N. Gusev, N. N. Volkova

The purpose of the study was to test individual differences in sensory sensitivity while performing signal detection and signal discrimination tasks. A total of 98 subjects performed two cognitive style tests on flexibility and rigidity of cognitive control, and focusing and scanning control, as well as two psychophysical tasks on visual signal detection (“yes/no” method) and loudness discrimination (“same/different”), each including two difficulty levels. Task type and difficulty level were considered as stimulation factors, and cognitive styles were considered as individual differences factors. The effects of both cognitive styles along with the effect of their interaction were revealed. ‘Flexible’ subjects and ‘scanners’ showed higher sensitivity in signal detection compared to ‘rigid’ subjects and ‘focusers’, respectively. Whereas no between-group differences were found in the accuracy of signal discrimination. Thus, we revealed individual differences in sensitivity, driven by cognitive style characteristics on the one hand, and task type on the other.
