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.

This study examined the role of verbal factors in visual learning and recognition of 36 good and 36 poor readers of normal intelligence. These second and third grade boys studied 3 sets of paired-associates in which pictorial stimuli were paired with letters, geometric designs, or abstract shapes. Recognition memory was assessed. Verbal factors measured were knowledge of names of letters and shapes, latency to label production, and verbal mediational strategies. Poor readers did not differ from good readers on any of the measures of verbal processing. Letters, geometric designs, and abstract shapes differed from one another on latency to production of labels or verbal codability. Poor readers performed significantly more poorly than good readers on the recognition task regardless of the codability of the stimuli. These findings are consistent with a perceptual deficit view of visual recognition problems of young boys who are poor readers.
