Does childhood activities preference affect gender differences in spatial abilities?
In a paper I published with C. Nolan and S. Voyer, I found that gender differences are only significant for those who played with non-spatial toys as children. I am currently pursuing a way to produce a more precise estimate of childhood toy preference. Preliminary work suggests that it might be possible to create a questionnaire that includes relatively independent scales measuring the spatial/nonspatial and masculine/feminine dimensions separately. However, I could use your help to further develop this!
