    Abstract:
    Neurocognitive assessment by dichotic digit test provides selective stimulation of auditory pathway with contralateral suppression of the ipsilateral showing interhemispheric differences in concurrent tasks. In order to recognize the pattern of responses, recovery order of digits and latencies heard the original test was modified with the addition of a record of an audio track of the responses. The sample includes subjects with a history in hearing specialization linked to the music and listen to comprehensive second language, normoacoustic without otologic diseases or neurological. Sets 20 pairs of dichotic digits with a digital recording for recording the subject's responses was used. The results reveal: right ear advantage in the pattern of correct answers and the order in which the information provided is retrieved. As for the pattern of intrasets latencies an increase to the fourth repeated / digit recovered and more blunder is observed. Declining intratest latencies in the second part of the test suggest positive training. These modifications allow new prospects and existing applications with behavioral tests.
