Objective: Continuous performance tests are known to typically measure sustained attention but usually also yield parameters that potentially measure other subprocesses of attention. The aim of the present study was to test the factor structure of the Conners's Continuous Performance Test (CCPT) in a heterogeneous clinical sample consisting of…

It was concluded that biofeedback-induced relaxation training increased attention to task and reduced impulsivity but did not affect the measure of locus of control on the population studied. (Author/SW)

Among findings from a comparison of 13 preschool hyperactive and control males assessed on receptive-communications tasks that required listening and delayed response were that Ss did not differ in task-related movements or verbalizations, but that hyperactive Ss verbalized impulsively during transitions and tasks requiring response delay.

Three groups of elementary school children, rated on activity and distractibility, were given a visual search task with three levels of display load and tested twice in two conditions of stimulus visibility. Encoding deficit or data limitation did not account for the attentional performance of either hyperactive or somewhat hyperactive subjects.…
