Up to now men had done better in previous orientation attempts with other things than food. The results published now suggest that spatial memory also depends on the type of landmarks, researchers said. Fruits, vegetables and other seasonal goods activated the spatial memory of women.
The differences between men and women have probably evolved in the course of evolution. In the time of the hunters and gatherers, the men had to be able to follow an animal over long distances and then find their way back with their prey. For women, however, it was advantageous if they could remember the location of food sources such as trees or berry bushes.
As further evidence for this hypothesis, the researchers assess the fact that in their study, the orientation ability of the participants also depended on the quality of the food. The more calories a food contained, the better the volunteers could remember where they had tasted it. This effect was seen in both women and men. displayJoshua New (Yale University, New Haven) et al .: Proceedings of the Royal Society B, Online Publication, DOI: 10.1098 / rspb.2007.0826 ddp / science.de?
