Mean frequency of successful power and precision grips in (a) peripersonal and (b) extrapersonal space across weeks. In peripersonal space, infants used the power configuration more than the precision grip for grasping the large ball, whereas they equally used the two grip configurations for grasping the small ball. When balls were presented in extrapersonal space, starting from the third week, infants used the power grip more often for the large ball than for the small ball, and conversely used the precision grip more for the small ball than for the large ball. Error bars show the S.E.M. *p < .01, **p < .001.
