【 摘 要 】

The aim of this study was to investigate lateral bias in patients with early-onset schizophrenia. Hand, eye, and foot preferences and relative hand skill were examined in early-onset patients (n = 44) and matched controls (n = 39), and were compared with population estimates. Patients demonstrated a significant excess in mixed handedness (20.5% vs. 8.5%) relative to population estimates and reduced relative hand skill on a pegboard task compared with controls. Left eye preference was significantly less common in schizophrenic patients relative to population estimates. Crossed eye-hand and eye-foot preferences were not significantly increased in the patient group as a whole but were present, respectively, in four of nine and five of nine mixed-handed patients but in none of five mixed-handed controls. These findings are consistent with the view that lateralisation is anomalous in schizophrenia early in the course of illness. (C) 2004 Elsevier Ireland Ltd. All rights reserved.
