Conjugate lateral eye movement and latency of verbal response to arithmetic questions.
24 left movers, 24 right movers and 24 mixed movers, categorized on the basis of their conjugate lateral eye movements, were measured on latency of verbal response to arithmetic questions. The predicted superiority of right movers in speed of response did not occur nor did interference with habitual direction of conjugate lateral eye movement affect results. However, the mixed group took longer to response to a second series of questions than did the left and right movers. This post hoc finding may indicate inefficient hemispheric competition within the mixed group when subjects are asked to add another task to that of arithmetic problem-solving.
