ESCUCHA DICOTICA by Eba Tomé | Free Listening on SoundCloud

In the early 60s, Eecucha Kimura reported that dichotic verbal stimuli specifically spoken numerals presented to a participant produced a right ear advantage REA. The cortical organization of speech processing.

In this article, we have reviewed recent findings from our laboratory, originally presented in Hugdahl et al. Relationship of imprecise corollary discharge in schizophrenia to auditory hallucinations. A study conducted involving the dichotic listening test, with emphasis on subtypes of schizophrenia particularly paranoid and undifferentiateddemonstrated that paranoid schizophrenics have the largest left hemisphere advantage — with undifferentiated schizophrenics where psychotic symptoms sicotica present but the criteria for paranoid, disorganized, or catatonic types have not been met having the smallest.
