Two studies were conducted to evaluate the ability of schizotypic subjects to track the horizontal movement of a light source across the face of an oscilloscope. In the first experiment, subjects were selected based on their scores on the Physical Anhedonia Scale (Chapman et al., 1976). The high anhedonic group was found to be significantly more variable than the low anhedonic group and contained three subjects with particularly deviant smooth pursuit eye movements (SPEM). In the second study, an additional group of schizotypic subjects who scored high on the Perceptual Aberration Scale (Chapman et al., 1978) was selected. In this study, eye-tracking records produced by both the anhedonic and perceptual aberration subjects were more variable than those recorded from control subjects, and once again, the most deviant records were produced by a small subgroup (n = 10) of the schizotypic subjects. These questionnaire-identified schizotypes with poor tracking ability might comprise a group of subjects especially vulnerable to a future schizophrenia-like disorder.
进行了两项研究，以评估分裂型人格受试者追踪示波器屏幕上光源水平移动的能力。在第一项实验中，根据受试者在《身体快感缺乏量表》（查普曼等人，1976年）上的得分进行选择。结果发现，高快感缺乏组的变异性明显高于低快感缺乏组，且该组中有三名受试者的平稳跟踪眼球运动（SPEM）特别异常。在第二项研究中，选择了另一组在《感知畸变量表》（查普曼等人，1978年）上得分较高的分裂型人格受试者。在这项研究中，快感缺乏和感知畸变受试者的眼动追踪记录比对照组受试者的记录变异性更大，而且，最异常的记录再次由一小部分（n = 10）分裂型人格受试者产生。这些通过问卷调查确定的追踪能力较差的分裂型人格者可能构成了一组特别容易患未来精神分裂症样疾病的受试者。
