The Relationship Between Hemispheric Interaction and Handedness on Verbal and Spatial Tasks

This study was designed to examine the relationship between hemispheric interaction, handedness and task performance. Participants included 36 female Framingham State College students, 18 of whom were left-handed and 18 right-handed. Participants completed two verbal and two spatial tasks in a counterbalanced order. Verbal tasks consisted of a free recall task and a paired associate task. Spatial tasks consisted of a mental rotation task and a water level task. Participants also completed the Edinburgh Handedness Questionnaire and a demographics questionnaire. Results indicated no significant differences between left and right handed participants on verbal task performance. Further, there were no differences between left and right handed participants on spatial task performance. This may indicate that hemispheric interaction has no effect on task performance.
