• The word processing ability of the right hemisphere with regard to word imageability was examined by the running memory span procedure. Forty right-handed college students participated. Seventy-six stimulus pairs were successively projected onto the both sides of a fixation-point, and the subjects were asked to judge if one of the presented stimulus pair has been presented before as quickly and accurately as possible. Each pair consisted of a highly imageable noun and a less imageable noun. As mental imagery has a facilitating effect on memory but not perception of words, memory load was systematically manipulated. Right visual field superiority was found for both HI and LI nouns at the immediate recognition condition. However, no significant visual field differences were found for HI nouns at delayed recognition conditions. These results suggest that the right hemisphere may take a certain role in mental imagery for memory tasks.
