Abstract
Previous laboratory studies that have either introduced extraneous environmental stimulation or tested children in cubicles have failed to provide support for the common clinical notion that hyperkinetic children are highly distractible. Based on the Rosenthal and Allen (1978) proposal, distractibility was investigated by introducing irrelevant information within the task context. Intratask distractibility was examined by comparing the performance of hyperkinetic and nonhyperkinetic children on a speeded classification task. Errors were measured for responses to slides containing either zero, constant, one varying, or two varying irrelevant stimulus dimensions. Dimensional salience of the three dimensions used in the study was measured for each child. The data indicate that hyperkinetics made more errors than nonhyperkinetics when constant irrelevant or two varying irrelevant dimensions were presented, but the two groups made equal errors when there was no irrelevant information presented within the stimulus array. No group differences in distractibility were found when the irrelevant dimension was low salience. It was concluded that salience of distractors presented within the task context may be useful in specifying the particular task conditions in which hyperkinetic children exhibit high distractibility.This publication has 15 references indexed in Scilit:
