“…Previous studies of intellectual functioningreveal fairly consistent, though not unequivocal, trends. Schizophrenics have been found generally to have lower childhood intelligence than their classmates in school (Albee, Lane, & Renter, ]964; Bower et al, 1960), though this finding was not replicated in a suburban population (Schaffner, Albee, & Lane, 1967), and lower childhood intelligence than their own siblings (Lane & Albee, 196S;Schaffner et al, 1967). Pollack, Woerner, and Klein (1970) found the same trends comparing schizophrenics against their siblings but similar (and stronger) results for patients with personality disorders, so they question whether lower childhood intelligence is specific to schizophrenic disorders.…”

Earlier project reports compared childhood social behavior of nonmigratory schizophrenics and normal classmates by analyzing teachers' comments in school records. This article expands the sample to include migratory schizophrenics and analyzes childhood intellectual functioning. Behavioral differences indicated emotional immaturity and social alienation in the preschizophrenics, with sharp sex differences. Preschizophrenic boys were abrasive and antisocial, whereas prcschizophrenic girls were introverted and socially insecure. No differences were associated with migration. The preschizophrenics had normal intelligence that remained stable throughout childhood, but overall scholastic performance was somewhat poorer than average. They achieved lower IQs than matched classmates, but differences from their own siblings were not significant. Childhood intelligence was not related to length of hospitalization. Implications for prediction of schizophrenia are discussed.One of the puzzlements about schizophrenic disorder is that when it occurs the afflicted person often changes quite dramatically. Recent advances in the study of the processreactive dimension (Garmezy, 1970;Kantor & Herron, 1966;Phillips, 1968) show that these changes are temporary in many cases but that in others indications of vulnerability that are reliably related to long-term psychi-
