gender differences at 6-10 months?

[Annette Hohenberger]

Dear list members,

I wonder if anybody could point out to me experiments that found gender 
differences at 6-10 months concerning the way boys and girls deal with 
conflicting information.
     An experiment was pointed out to me where infants had to produce an 
effect by pulling a string. If pulled suddenly, the effect was cancelled 
- which amounts to a rule change or violation-of-expectation. Whereas 
the boys tried again and again, the girls cried and turned to their 
mother. Another gender difference was documented concerning habituation 
time. Does anybody know of these or similar experiments?
I would appreciate a lot if someone could point out any relevant 
information to me.
Thanks a lot and best regards,

-Annette Hohenberger
