EFFECTS OF THE INTENSITY OF AUDITORY AND VISUAL READY-SIGNALS ON SIMPLE REACTION TIME
Abstract
The effects of auditory and visual ready-signal intensity were investigated in a simple reaction time (RT) task. Mean RT to three auditory response-signals was found to systematically increase with a corresponding increase in the intensity of either auditory or visual ready-signals. The results were analyzed according to a decision model of stimulus intensity effects. It was concluded that ready-signal intensity influenced the value of the detection criterion. Practice effects and individual differences were also significant determinants of the criterion level.
