If Infants Look Longer at a Video Display That Shows

If infants look longer at a video display that shows another infant's legs moving than at a video display that shows their own legs moving, researchers studying intermodal perception have concluded that

A) infants younger than 8 months are unable to integrate visual and proprioceptive information
B) infants younger than 8 months do not notice that the movements of the other infant's legs do not match their own legs' movements
C) infants younger than 8 months are sensitive to the absence of a contingency between the feeling of their own legs' movements and the image of the other infant's legs moving
D) infants younger than 8 months are capable of cross-modal perception but not intermodal perception
