Gender differences in laterality on a dichotic task: the influence of report strategies.

Full Abstract

Four experiments were conducted to investigate the influence of report strategies on gender differences in laterality. Ten males and 10 females completed a dichotic consonant-vowels pairs task under four conditions manipulating reporting strategies. Free recall allowed participants to report syllables in any order they chose, whereas order of report control required the report of a pre-specified ear first. In focused attention, they reported only one response from a pre-specified ear. Finally, in ABX discrimination, participants were required to indicate whether a binaural probe was one of the stimuli presented dichotically on the same trial. It was hypothesized that improved control of report strategies would increase the likelihood of detecting significant gender differences in laterality. This was confirmed when results showed no significant gender differences in laterality for the free recall and order of report control conditions, whereas focused attention produced marginal gender differences and clearly significant differences were obtained in the ABX discrimination condition. These findings have implications for interpretations of gender differences in laterality based on strategy effects. Interpretations emphasize the role of attention deployment in the measurement of laterality.
