Study: Men Better at Hearing, Watching Than Women

It is well-known that men often take less time parking their cars and have less trouble than women in navigating in a new city, meaning men excel in what are known as visuo-spatial abilities.

Now, a new study has demonstrated that men excel in hearing task also.

On the other hand, women are known to be more verbally fluent, have better manual dexterity and are better at noticing things.

Ida Zundorf from the Center of Neurology at Tubingen University, together with Prof. Hans-Otto Karnath and Dr. Jorg Lewald, investigated the audio-spatial abilities in healthy men and women by means of a sound-localization task.

Participants were asked to listen to sounds and determine the location of the sound source, either by pointing towards it or by naming the exact position (e.g. 45 degrees left). At first, sounds were presented one at a time and both men and women accomplished the task with great accuracy. Later, several sounds were presented simultaneously and participants had to focus on and localize only one sound.

This is known as the cocktail party phenomenon - the human capacity to detect and focus on one particular sound source in a noisy environment. Interestingly, women found the second task much more difficult, compared to men, to the extent that in some cases they even thought the sounds were coming from the opposite direction.

These results suggest that men are not only better at visuo-spatial tasks, but also in auditory-spatial tasks. Since this male advantage was only found in the cocktail party situation, i.e. women performed equally well when sounds were presented one at a time, this indicates that the difference is related to a "high attentional mechanism" in the brain specifically involved in extracting spatial information of one particular sound source in a noisy environment. It has been speculated that men have developed these spatial abilities as the result of natural and sexual selection throughout human evolution.

The findings have been published in the issue of Elsevier's Cortex.
