Distractibility in children vulnerable to psychopathology.

Evaluated children (mean age 15.25 yrs) of schizophrenics (n?=?36), unipolars (n?=?57), bipolars (n?=?60), and normals (n?=?65) on a digit span measure of distractibility with the distraction and nondistraction conditions matched for discrimination power. Whereas there were no between-groups differences in performance in the nondistraction condition, children of schizophrenics and unipolars performed more poorly than children of normal parents in the distraction condition. Analyses of serial position curves revealed that children of schizophrenics performed more poorly on primacy as compared to recency portions of distraction trials. This finding differentiated children with a schizophrenic parent from children in each of the other groups. Results indicate that children of schizophrenics have a deficit in controlled information processing. (23 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)
