Threatening Stimuli

The present investigation tested the hypothesis advanced by J. Inglis (1961) that perceptual defense and perceptual vigilance result from an interaction between personality differences and degrees of experimental stress. The design, which controlled for questionable procedures used in previous studies, utilized 32 introverts and 32 extraverts, half male and half female, in an experiment with a visual recognition-task. Results indicated that under low-stress conditions introverts and extraverts identified by their response to a thematic apperception task react to threatening stimuli with perceptual defense and perceptual vigilance, respectively. Under high-stress conditions, type of avoidance activity reverses; extraverts react with perceptual defense and introverts with perceptual vigilance. It was suggested that, when both personality and stress variables are controlled, results of the perceptual defense paradigm are predictable and consistent, in support of Inglis' hypothesis.

Cognitive Rigidity

Three groups, one of elderly, one of young mentally retarded, and one of non-retarded young persons were compared on a visual recognition task which involved changing from one category of identification to another. The mentally retarded participants had greater difficulty in changing categories than did the non-retarded participants. Results for the elderly were similar but may have been partly due to the choice of stimulus material. In a second task, the same elderly and non-retarded young participants named as many objects as possible in one minute. The elderly group produced fewer responses on average than the young group and fewer categories of such responses. Results suggested that older persons find it more difficult to change between different categories of identification.
