Hemispheric correlation with psychomotor learning in manual communication tasks

Abstract

The objective of this study was to establish a correlation between hemispheres and the psychomotor learning in connection with the gesture communication. According to Moura (1993), when the gesture com- munication is practiced, especially in the Brazilian Sign Language (LIBRAS), each of the brain hemispheres of the listening person reveals a decode predominantly different. Therefore, left hemisphere prevails the linguistic functions, and right hemisphere the space-vision. In this survey we had the participation of one hundred students of both sexes, between 15 and 17 years old, with high school level attending one private school in the city of Rio de Janeiro. Once selected, the group was submitted to the CLEM TEST to identify the preference of the hemisphere processing. The students were divided in three hemispheric groups, that is, the right hemisphere (HR), the left hemisphere (HL) and the bi- hemispheres (HRL) .The components of each group were then submitted to a individual selective test including signifi cative competency in relation to the communicative gestures signs. Analysis of variance was performed between the three groups (p < 0,05). The especifi c sign ,regarding the performance of each student, indicated evidences that the linguistics aspects are preferably processed in the left hemisphere.
