Abstract

Subjects identified on the basis of sex, handedness, and handwriting posture performed a letter-naming task. Single letters were shown briefly in the left or right visual field and the subject was required to name the letter as quickly as possible. Both left- and right-handers had shorter response latencies when the stimulus was presented in the left visual field. Response latency decreased across trials, however, the decrement was largest to right visual field stimuli. In addition, males produced significantly faster reaction than did females.

摘要

根据性别、用手习惯和书写姿势确定的受试者进行了字母命名任务。单个字母短暂地出现在左视野或右视野中，要求受试者尽快说出该字母。当刺激出现在左视野时，左撇子和右撇子的反应潜伏期都较短。然而，反应潜伏期在各次试验中都有所下降，不过，对右视野刺激的下降幅度最大。此外，男性的反应速度明显比女性快。
