Abstract:

The present study investigated effects of 1 the stated probability at .25 versus .85 with no pretest shock demonstration and 2 pretest shock demonstration versus no demonstration with the stated probability held constant at .65. Subjects were 70 entering aviation trainees. The task was a subject-paced, four-choice discrimination task. Ten subjects were used as controls, with the remainder divided among the experimental conditions. A 5-minute practice period without threat preceded a 5-minute experimental period for all conditions. It was concluded that 1 shock demonstration is not necessary, and its elimination would provide a more useful range for individual difference measurement 2 .65 probability is better for producing measurable performance decrement than either the lower or higher extremes of .25 and .85 3 threat perception as measured by mean performance level across time may be as useful a parameter as performance decrement immediately preceding the anticipated harmful stimulus.
