Response uncertainty and imitation: The interactive effects of age and task options

It was reasoned that younger children would be more susceptible to situational uncertainty and thereby imitate more than older children or peers of the same age tested under more structured conditions. Children 6- through 8- and 12- through 14-years-old observed a model toss a bean bag at a target and were tested for target relevant and incidental imitation under conditions of two task options (high structure) or 10 task options (low structure). On both measures of imitation, preadolescents in the low structure condition imitated significantly more than adolescents. Preadolescents also imitated more incidental behavior in the low than in the high structure condition. Additionally, it was found that personality variables predicted imitative behavior of younger subjects in the low structure condition only.

Interactive effects of age and cerebral disease on cognitive performances.

A battery of mental tests was given to groups of younger (16--44 years) and older (48--60 years) control and cerebral diseased patients. Each patient in the younger cerebral diseased group was matched individually with an older cerebral diseased patient for type and site of lesion. Each patient with cerebral disease was matched individually with a control patient for age, educational level and sex. Differences in level of test performance related to age were generally greater for cerebral diseased than for control patients. Differences in level of test performance related to diagnostic category were generally greater for older than for younger patients. Analysis disclosed a significant overall interactive effect of age and cerebral disease on the performance of mental tests, supporting the hypothesis that acquired cerebral disease has more severe behavioral consequences in older than in younger persons.

Interactive effects of age and brain disease on reaction time.

Simple visual and auditory reaction time (RT) was studied in younger (16 to 44 years old) and older (46 to 63 years old) control and brain-diseased patients. Differences in RT related to age were larger for brain-diseased than control patients. Differences in RT related to diagnostic category were larger for older than younger patients. Analysis indicated an interactive effect of age and brain disease on RT supporting the suggestion that acquired brain disease leads to a more pronounced retardation in RT in older patients.
