The to me surprising result was that women performed better than men (which is to my knowledge not often the case in typical orientation experiments) and that independent of gender the amount of calories that are contained in the tasted food influenced the performance. Basically if there are more calories in the tasted food people could remember better where it was. I have had no change yet to read the original paper (Joshua New, Max M. Krasnow, Danielle Truxaw und Steven J.C. Gaulin. Spatial adaptations for plant foraging: women excel and calories count, August 2007, Royal society publishing, http://www.journals.royalsoc.ac.uk) and my assessment is only based on the post in the newsticker.
This makes me think about future navigation systems and in particular landmark based navigation. What landmarks are appropriate to use (e.g. places where you get rich food) and how much this is gender dependent (e.g. the route for men is explained by car-dealers and computer shops whereas for women by references to shoe shops – is this political correct?).
Apropos: landmark based navigation. There is an interesting short paper that was at last years UIST conference that looks into this issue in the context of personalized routes:
Patel, K., Chen, M. Y., Smith,
Perhaps this ideas could be useful for a future navigation system…
