Testosterone levels affect linguistic abilities 2007-07-12
Research highlights the impact of hormones on language
Victor Boucher and Charles Lamoureux.
Research has shown that women are better than men at games involving letters and words such as Scrabble. Women usually have a broader vocabulary than men, and speech development problems usually affect men three times as often.
Charles Lamoureux, soon-to-be PhD graduate of the Department of linguistics and translation, measured for the first time the impact of testosterone levels on linguistic and speech functions. The research was conducted under the supervision of Victor Boucher, and the results were presented at the ACFAS congress last May.
The first exercise consisted of asking 20 male subjects to list as many words as possible starting with the letter R in 60 seconds. The exercise was then repeated with the letter L. Testosterone levels were measured using saliva samples. Results indicated that the higher the level of testosterone the lower the number of words listed.
The individual with the highest level of testosterone listed 18 words, while the one with the lowest level of testosterone listed 31 words, explains Charles Lamoureux. The proposed explanation is that testosterone reduces the speed of lexical access. It is possible that men have as broad a vocabulary as women, but that they have a harder time accessing it.
To support his hypothesis the student cites research, which indicates that transsexuals who went from women to men often had difficulty with language following the testosterone treatments.
Both Lamoureux and Boucher consider an evolution aspect to the theory as well. According to the theory, masculine skills favored by evolution such as hunting required less vocabulary, while women who were left in charge of the children, required stronger communication abilities. In fact, a broad vocabulary could have been to the detriment of males in a hunting context who needed to react quickly and precisely.
