Measures of selective attention and speed which have been employed in the study of disturbances of cognitive functioning in schizophrenia were used in a study of 20 MZ and 20 DZ normal twin pairs. Results suggest the presence of a genetic contribution to scores on such tasks, particularly for the speed measures.
在一项针对20对同卵正常双胞胎和20对异卵正常双胞胎的研究中，采用了用于精神分裂症认知功能障碍研究的选择性注意力和速度测量方法。结果表明，这些任务的得分存在遗传因素的影响，尤其是在速度测量方面。
