THE OBJECT IDENTIFICATION TEST: A STRESS-SENSITIVE PERCEPTUAL TEST.
Abstract
The purpose of this study was to develop additional items for the Object Identification Test (OIT), a test designed to measure some effects of environmental stress on human perceptual performance. Each item of the OIT consists of an ordered series of seven line drawings: the first drawing in a series presents a relatively ambiguous stimulus; details are added to successive drawings until, in the last drawing, an easily recognizable common object is pictured. The subject responds to each drawing of an item; his score is the drawing number on which he correctly identifies the object. Performance on the OIT involves central perceptual processes, and it is assumed that stress affects those processes. There is evidence that performance on the OIT is affected by at least three kinds of stress: intense noise exposure, noxious stimulation of test-related stimuli, and extended close confinement.
