PROCESSING AUDITORY INFORMATION - INTERFERENCE FROM AN IRRELEVANT CUE

In a choice RT task, 64 undergraduates pressed either a right- or left-hand key in response to directional commands provided by 400- and 1000-cps tones. On monaural trials, RT was significantly faster when the meaning of the tonal command corresponded with the ear in which it was heard (corresponding trials) than when it did not (noncorresponding trials). A comparison of monaural with binaural RT indicated that this Tonal Command * Ear Stimulated interaction was due to interference on the noncorresponding monaural trials rather than facilitation on the corresponding trials.
