We humans prefer to be addressed in our right ear and are more likely to perform a task when we receive the request in our right ear rather than our left. In a series of three studies, Dr. Luca Tommasi and Daniele Marzoli from the University "Gabriele d'Annunzio" in Chieti, Italy, show that a natural side preference, manifests itself in everyday human behaviour.
Until
now, the majority of studies looking at ear preference have been controlled
laboratory studies and there is very little published observational evidence of
spontaneous ear dominance in everyday human behavior.
Their
three studies specifically observed ear preference during social interactions
in noisy night club environments. In the first study, 286 clubbers were
observed while they were talking, with loud music in the background. In total,
72 percent of interactions occurred on the right side of the listener. These
results are consistent with the right ear preference found in laboratory
studies and they demonstrate that the side preference is spontaneously
displayed outside the laboratory.
In
the second study, the researchers approached 160 clubbers and mumbled an
inaudible, meaningless utterance and waited to see which ear they offered. They
then asked them for a cigarette. Overall, 58 percent offered their right ear
for listening and 42 percent their left. Only women showed a consistent
right-ear preference. In this study, there was no link between the number of
cigarettes obtained and the ear receiving the request.
In
the third study, the researchers intentionally addressed 176 clubbers in either
their right or their left ear when asking for a cigarette. They obtained
significantly more cigarettes when they spoke to the clubbers' right ear
compared with their left.
According
to the authors, taken together, these results confirm a right ear/left
hemisphere advantage for verbal communication and distinctive specialization of
the two halves of the brain. They conclude: "Our studies corroborate the
idea of a common ancestry of lateralized behaviour during social interactions,
not only for species-specific vocal communication, but also for affective
responses."
