The relationship between ‘impulsiveness’ and hemispheric functional asymmetry, investigated with a divided visual field word recognition task
Thirty-six subjects underwent a divided visual field recognition task in which four-letter words were presented tachistoscopically in the left and right visual hemifields. The percentage of words presented in the right hemifield which were correctly reported (R%) was significantly negatively correla...

Summary: | Thirty-six subjects underwent a divided visual field recognition task in which four-letter words were presented tachistoscopically in the left and right visual hemifields. The percentage of words presented in the right hemifield which were correctly reported (R%) was significantly negatively correlated with a measure of impulsiveness derived from the Matching Familiar Figures Test. Independent relations between R% and age, estimated IQ, and trait anxiety were also found. There was no significant relation between the percentage of words presented in the left hemifield which were correctly reported (L%) and impulsiveness. The results are consistent with the suggestion that processing of verbal information by the left cerebral hemisphere may be less efficient in impulsive than in normal individuals. |
