A choice-reaction time task utilizing congruent and incongruent colour/word stimuli: another reaction to Stroop.
A choice reaction time task was devised, using incongruent colour/word (Stroop-type) and congruent colour/word stimuli. A significant difference was found between reaction times to the two stimulus types with the Stroop-type stimuli eliciting longer reaction times. It is argued that traditional hypotheses about channel limitation can not explain this finding; the suggestion that the delay may lie in the decision-making process is put forward.
