A component analysis of attentional problems of educationally handicapped boys.
Seventy-three educationally handicapped (EH) and 78 regular class, normally achieving (NA) boys grades 3-8 were tested with a series of measures selected to test three components of attention: coming to attention, decision making, and maintaining attention over time. EH and NA samples were subdivided into three gropus by grade level (grades 3-4, 5-6, and 7-8). Based on a teacher-completed behavioral check list, the EH group was further subdivided according to pupils perceived by teachers as hyperactive or nonhyperactive. With the exception of the youngest group, EH and NA samples did not differ from each other on CA, but regular class boys had slightly higher IQs and better reading scores than did their EH peers; EH hyperactives and EH nonhyperactives differed significantly on reading scores, the difference favoring the nonhyperactives. All pupils were individually administered the Children's Embedded Figures Test (CEFT), the Matching Familiar Figures Test (MFFT), and the Children's Checking Task (CCT), the last designed specifically to assess ability to maintain attention over time. EH pupils did not function as efficiently or as accurately on the attentional tasks as did their normally achieving age peers. Significant differences between EH and NA samples were found for CEFT and MFFT errors, as well as for CCT errors of omission and commission. Analyses of the EH group according to hyperactive--nonhyperactive status were for the most part nonsignificant. Correlational analyses yielded low but statistically significant relationships among the attentional measures, but nonsignificant relationships between IQ and the attentional test scores. Findings were consistent with the interpretation that the three hypothesized components of attention are partially independent and thus may have differential influence on pupils performance in school.
