Abstract
The present research attempted to determine whether the typical pattern of responding found with Stroop stimuli is also found when the stimuli are printed vertically, printed vertically with three-letter abbreviations, and printed horizontally with three-letter abbreviations. Response times were recorded for reading, color naming, and conflict (interference) tasks, with the primary performance measure being the ratio of the conflict score to the color naming score. Three groups of subjects responded to modified Stroop stimuli and one group was presented conventional Stroop stimuli, thereby serving as the reference, or control, group. No significant difference was found among the groups on the ratio measure. These results were interpreted as evidence that Stroop stimuli can be modified in several ways, while still retaining inference qualities. Implications of this research, particularly with regard to investigations of hemispheric asymmetry and sex differences, are discussed.
