It’s the latest in a series of studies that show that sound from both human ears is processed differently within the brain. Researchers have noted that humans tend to have a preference for listening to verbal input with their right ears and that given stimulus in both ears, they’ll privilege the syllables that went into the right ear. Brain scientists hypothesize that the right ear auditory stream receives precedence in the left hemisphere of the brain, where the bulk of linguistic processing is carried out.
What’s surprising about the study is that ear choice had such a decided impact on the behavior of participants in a natural, or as the researchers put it, ecological, setting. Why would people feel more generous when their right ears are addressed?
The authors (Marzoli and Tommasi) write that some work has shown that the left and right hemispheres of the brain appear to be tuned for positive and negative emotions, respectively. Talk into the right ear and you send your words into a slightly more amenable part of the brain.
Esta conclusión es parte de un estudio que se realizó en un bar en Italia en donde, por el volumen de la música, es necesario que las personas se hablen al oído.
