Men Advance, women retreat

As Scientific American remarks, this is a case where we have experimental results waiting for an explanation.  It’s very tempting to make some up, but I’ll have to have more coffee before I can  do that.

A group from the Southern Cross University in Australia published a fascinating result in the journal Current Biology, after they manipulated the light points of walkers, making figures appear more feminine or masculine.

If they made the point-form body appear male, subjects perceived that figure as walking toward them—regardless of its actual direction. If the walker seemed female, the subjects reported it was walking away from them.

Curiously, gender-neutral figures tended to appear to be moving toward the viewer. “It was only when walkers had characteristics consistent with being female did the observers begin to perceive them more often as facing away,” the researchers reported.

And the article’s abstract:

The sensitivity of the mammalian visual system to biological motion cues has been shown to be general and acute. Human observers, in particular, can deduce higher-order information, such as the orientation of a figure (which way it is facing), its gender, emotional state, and even personality traits, on the basis only of sparse motion cues. Even when the stimulus information is confined to point lights attached to the major joints of an actor (so-called point-light figures), observers can use information about the way the actor is moving to tell what they are doing, whether they are a male or female, and how they are feeling. Here we report the novel finding that stimulus manipulations that made such walkers appear more female also had the effect of making the walkers appear more often as if they were walking away from rather than towards observers. Using frontal-view (or rear-view) point-light displays of human walkers, we asked observers to judge whether they seemed to be walking towards or away from the viewing position. Independent of their own gender, observers reliably reported those figures they perceived to be male as looking like they were approaching, but those they perceived to be female as walking away. Furthermore, figures perceived to be gender-neutral also appeared more often, although not exclusively, to be walking towards observers.

  1. Jender, it is strange. It may be that the difference comes from the different proportions and so not directly from the gender. Still, it will have implications about viewing different genders.

    It’s a very good journal, so I’d think it got pretty careful peer review.
