HEMISPHERIC TEACHING STRATEGIES IN THE ACQUISITION AND RETENTION OF A MOTOR SKILL

An extreme preference in processing information within either the left or right hemisphere is known as hemisphericity. A previous study investigating hemisphericity as a factor in motor skill learning (Murray, 1979) found that matching subjects' hemisphericity characteristics with hemispherical teaching strategies enhanced skill acquisition. In contrast, our study examined the effects of hemispherical teaching strategies on a group of subjects who did not present hemisphericity. Right-handed male high school students were randomly assigned to either a left hemisphere, right hemisphere, or an interhemispherical teaching condition. Subjects in the right hemisphere and interhemispherical conditions performed and learned the skill more effectively than subjects in the left hemisphere teaching condition. The right hemisphere and interhemispherical groups performed comparably in acquisition; however, the interhemispherical group showed significantly better retention of the skill. Motor skill acquisition and retention for nondominant processors appears best served by directing both verbal and nonverbal attention to the skill.
