Seeing pictures of objects activates the motor cortex and can have an influence on subsequent grasping actions. However, the exact nature of the motor representations evoked by these pictures is unclear. For example, action plans engaged by pictures could be most affected by direct visual input and computed online based on object shape.…

A hierarchical progression in infants' ability to use surface features, such as color, as a basis for object individuation in the first year has been well established (Tremoulet, Leslie, & Hall, 2000; Wilcox, 1999). There is evidence, however, that infants' sensitivity to surface features can be increased through multisensory (i.e.,…

Priming studies have demonstrated that an object's intrinsic and extrinsic qualities (size, orientation) influence subsequent motor behavior thus suggesting that these object qualities "afford" actions that are congruent with the prime. We present four experiments that aim to evaluate the relative effect of conceptual and physical object qualities…
