Increased incidence of left-eye and crossed hand-eye dominance have been considered as indicating left hemispheric dysfunction in many neuropsychiatric disorders. This study investigates the incidence of left-eye and crossed hand-eye dominance in patience with schizophrenia (n = 68), panic disorder (n = 62), personality disorder (n = 35), heroin addiction (n = 54), and mental retardation (n = 33), in comparison with controls (n = 944). All psychiatric groups, except the group with panic disorder, had significantly greater frequency of left-eye dominance than the control group. Furthermore, all psychiatric groups, except the personality-disordered group, had significantly greater frequency of crossed hand-eye dominance than the control group. These findings further support the evidence of an anomaly in hemispheric lateralization among different psychiatric populations, particularly among those with psychotic symptoms and cognitive deficits.
在许多神经精神疾病中，左眼优势和交叉手眼优势发生率的增加被认为表明左半球功能障碍。本研究调查了精神分裂症患者（n = 68）、惊恐障碍患者（n = 62）、人格障碍患者（n = 35）、海洛因成瘾者（n = 54）和智力障碍者（n = 33）中左眼优势和交叉手眼优势的发生率，并与对照组（n = 944）进行比较。除惊恐障碍组外，所有精神疾病组的左眼优势发生率均显著高于对照组。此外，除人格障碍组外，所有精神疾病组的交叉手眼优势发生率均显著高于对照组。这些发现进一步支持了不同精神疾病人群中半球侧化异常的证据，尤其是那些有精神病性症状和认知缺陷的人群。
