| Abstract: | Evaluated global attentional deficits as possible childhood markers of schizophrenia. Performance deviance was assessed across a continuous performance test, an attention span task, and the Digit Span subtest of the Wechsler Intelligence Scale for Children (WISC). 63 children of schizophrenic parents, 43 children of parents with affective disorders, and 100 children of normal parents were tested when the children were 7–12 yrs old. A subgroup of Ss at risk for schizophrenia displayed extreme global deviance across attentional measures. Only a small number of Ss at risk for affective disorders and normal comparison Ss showed similar extreme attentional deficits. The global attentional deficits measured at these early ages were related to behavioral disturbances (behavior was assessed in 3–6 mo intervals since 1971) in young adulthood for Ss at risk for schizophrenia, but not for Ss in the affective risk group or in the normal comparison group. It is concluded that global attentional deficits have considerable specificity for predicting behavioral problems thought to be precursors of schizophrenia or schizophrenia-related disorders.
