“Motor Affordances in Visual Working Memory”

T: None.

  • switching modalities between stimuli incurs (cognitive?) processing costs H: same for m. reps (Banana-yellow & gemstone-glitters) vs. (banana-yellow and marble-cool)

Supports thesis that MR “runs” on sensorimotor system

Affordances: potential actions to be performed with objects by organism

Visual working memory- do affordances play a role? (Would make the system more efficient) * assuming of course there's no cognitive cost greater than coming up with an affordance on demand

Other issues- trials have not isolated working memory from long-term; only resulted in premotor cortex activation

H: if -T, then motor interference should interfere w’ memory for manipulator objects more than non-manipulable ones
