Although action experience has been shown to enhance the development of spatial cognition, the mechanism underlying the effects of action is still unclear. The present research examined the role of visual cues generated during action in promoting infants' mental rotation. We sought to clarify the underlying mechanism by decoupling different…

It is well known that viewing graspable tools (but not other objects) activates motor-related brain regions, but the time course of affordance processing has remained relatively unexplored. In this study, EEG was continuously recorded from 128 scalp sites in 15 right-handed university students while they received stimuli in the form of 150…

Sighted subjects assembled puzzles under separate conditions of visual-haptic perception and used vision and touch simultaneously to illustrate visual-type involvement and links in haptic encoding processes. A cognitive component in perceptions was found. When visual input was inadequate or independent of haptic perception, tactual information was…

Two experiments show that action alters the shape categories formed by 2-year-olds. Experiment 1 shows that moving an object horizontally (or vertically) defines the horizontal (or vertical) axis as the main axis of elongation and systematically changes the range of shapes seen as similar. Experiment 2 shows that moving an object symmetrically (or…
