We examined the impact of presentation of voice stimuli on the Stroop effect.
We operated spatial location and meaning of visual words in terms of space, meaning of auditory stimuli, and the stimuli-onset asynchrony (SOA) between visual and auditory stimuli. Furthermore we operated two modes of responses between key-press and vocal responses. Consequently, we obtained four significant effects; congruency of visual stimuli, meaning of auditory stimuli, response mode and SOA. The impact of auditory stimuli was greater when the visual stimuli preceded the auditory stimuli in vocal-response mode. It suggests that auditory stimuli make activation of semantic representation faster than visual words.
