Describes various performance measures used in a study to investigate the relation of performance pace to age and information processing ability. Test results indicated no differences in performance pace but differences in performance quality between young and older individuals, with implications for hiring and training older workers. (MF)

The purpose of this experiment was to determine whether age differences noted when two tasks are performed concurrently can be accounted for in terms of age differences in single task baseline performance. Subjects were two groups of 12 eight-year-olds, and one group of 12 thirteen-year-olds. (CM)

It is concluded that attentional capacity is independent of intelligence, and that critical changes in this capacity may occur between ages 8 and 9. (Authors)

The performance of the older subjects (10 years and up) was facilitated by the organizational cues, whereas that of younger subjects was not. (Author)

A decrement toward lowered levels of cognitive functioning was noted in a study of aged residents of a dependent care facility when tested on a series of cognitive conservation tasks. (Author/KM)

A change commonly found in older persons is a general tendency for responses to external stimuli to be slowed. The document includes a review of theoretical approaches to the explanation of slowing on cognitive tasks that occur with age, and reviews the methodology of a two-part experimental study of 45 subjects. The study reports a…

Results indicate that the auditory stimulation in no way affected task performance. Author argues that great amounts of money should not be spent by either schools or parents in order to eliminate moderate amounts of noise from a child's academic environment. (Author/CB)

An assessment was made of 5- and 8-year-old children's performance on a short-term memory task under two auditory and two visual distraction conditions, as well as under a nondistraction condition. Performance under nondistraction was found to be superior to that under distraction (p<.001), indicating that the extraneous stimuli had a generally…

Study deals with a comparative developmental analysis of performances on the same task by four age groups. (MB)

Verbal and pictorial class-inclusion questions were presented to children in kindergarten through grade 6. The data indicates that the purely verbal form of the question was less difficult for the children to answer than the pictorial form. (Author/CS)

Compared were performances of 39 educable mentally retarded (EMR) Ss, mean chronological age (CA) 11 1/2 years, mean mental age (MA) 7 3/4 years; 25 fifth graders matched on CA; and 27 second graders matched on MA to determine whether children of different ages and IQ spontaneously demonstrate learning strategies after repeated practice with…

The relation of CA, MA, and IQ to conservation was examined by comparing the performance of bright, normal, and retarded children matched on the critical MA of six years. (Author)
