Further Evidence of Asymmetrical Processing of Tachistoscopic Inputs in Undergraduates across Sex, Handedness, Field-Side, and Fixation Instructions.
Iaccino, James F.
A study examined laterality effects observed in previous studies in which men as well as right-handers show a right-visual field (RVF) advantage for letter recall and a left-visual field (LVF) advantage for letter position recall, suggesting asymmetrical brain organization for these groups. Subjects, 96 undergraduates equally divided by sex and hand dominance, were required to recall either the letters or the respective letter positions within 4x4 matrices flashed to the right or the left visual field. Subjects further received instructions prior to each trial cueing them as to the field in which the matrix would be positioned. Results indicated that right-handed men demonstrated the predicted RVF advantage for letters while only right-handed subjects evidenced a LVF advantage for letter positions. Findings suggest that the instructions could have been contributing to the observed sex difference with letters, implying that right-handers exclusively possessed this asymmetrical organization.
