Lateral eye movement and hemisphere asymmetry: effects of question type, task type, emotion type, and individual differences.
The validity of lateral eye movement (LEM) as an index of hemispheric activation was examined with a series of experiments. LEMs were measured to verbal and spatial questions (Experiment 1), word detection and emotion detection tasks (Experiment 2), and to negative and positive emotions (Experiment 3). The results of these three experiments showed that LEM is not a sensitive index of hemispheric activation. Experiment 4 showed that individual differences in LEM patterns is relatively stable and may reflect some personality traits.
