I talked recently about how the well-established difference in spatial ability between men and women apparently has a lot to do with confidence. I also mentioned in passing that previous research has shown that training can close the gender gap. A recent study suggests that this training may not have to be specific to spatial skills.
In the German study, 120 students were given a processing speed test and a standard mental rotation test. The students were evenly divided into three groups: musicians, athletes, and education students who didn’t participate in either sports or music.
While the expected gender gap was found among the education students, the gap was smaller among the sports students, and non-existent in the music students.
Among the education students, men got twice as many rotation problems correct as women. Among the sports students, both men and women did better than their peers in education, but since they were both about equally advantaged, a gender gap was still maintained. However, among the musicians, it was only women who benefited, bringing them up to the level of the men.
Thus, for males, athletes did best on mental rotation; for females, musicians did best.
Although it may be that those who went into music or sports had relevant “natural abilities”, the amount of training in sports/music did have a significant effect. Indeed, analysis found that the advantage of sports and music students disappeared when hours of practice and years of practicing were included.
Interestingly, too, there was an effect of processing speed. Although overall the three groups didn’t differ in processing speed, male musicians had a lower processing speed than female musicians, or male athletes (neither of which groups were significantly different from each other).
It is intriguing that music training should only benefit females’ spatial abilities. However, I’m reminded that in research showing how a few hours of video game training can help females close the gender gap, females benefited from the training far more than men. The obvious conclusion is that the males already had sufficient experience, and a few more hours were neither here nor there. Perhaps the question should rather be: why does sports practice benefit males’ spatial skills? A question that seems to point to the benefits for processing speed, but then we have to ask why sports didn’t have the same effect on women. One possible answer here is that the women had engaged in sports for a significantly shorter time (an average of 10.6 years vs 17.55), meaning that the males tended to begin their sports training at a much younger age. There was no such difference among the musicians.
