Sroufe, L. Alan – Developmental Psychology, 1971
Thirty 6-, 8-, and 10-year-old boys were subjects in this study whose findings suggest that the obtained differences in anticipatory heart-rate deceleration reflect developmental changes in the ability to maintain attention. (WY)

Morrison, Frederick J. – Journal of Experimental Child Psychology, 1982
To explore possible age differences, the first experiment assessed speed and maintenance of alertness in 5-year-olds, 8-year-olds, and adults. The second study tested the hypothesis that developmental variation in processing speed observed in some studies was attributable in part to age differences in alerting processes. (MP)

Kirby, N. H.; And Others – American Journal of Mental Deficiency, 1982
When two nonoperative lights were added to each of the ends of a stimulus display in a four choice reaction time (RT) task, the RTs of mentally retarded and nonretarded young adults Ss were slowed to about the same extent. (Author)

Carter, Phillip Dean – Lifelong Learning: The Adult Years, 1982
Hearing loss, vision loss, and other physical impairments which are natural parts of the aging process can be compensated for in planning learning for older adults. Such impairments should not be taken as restrictions on the older adult's ability or desire to learn. (SK)

Ratcliff, Roger – Journal of Experimental Psychology: Learning, Memory, and Cognition, 1982
A standard reaction time procedure and a response signal procedure were used on data from eight experiments on semantic verifications. Results suggest that simple models of the semantic verification task that assume a single yes/no dimension on which discrimination is made are not correct. (Author/PN)

Mayer, Richard E. – Journal of Experimental Psychology: Learning, Memory, and Cognition, 1982
Equation problems elicited a strategy in which the subject attempted to isolate the X variables on one side of the equation, whereas word problems elicited a strategy in which the subject attempted to reduce the expression. These results suggest that problem format influences the type of strategy used to solve algebra problems. (Author/PN)

Lewis, Marc S.; And Others – Journal of Consulting and Clinical Psychology, 1979
Psychological tests were administered to a crisis group undergoing surgery for cancer and to a comparison group on the night before surgery and thereafter at three-week intervals. Results indicated significant psychological changes only in the crisis group. Duration of crisis was greater than six weeks but less than seven months. (Author)
