  • Abstract Two experiments establish links between desired knowledge about objects and hand movements during haptic object exploration. Experiment 1 used a match-to-sample task, in which blindfolded subjects were directed to match objects on a particular dimension (e.g., texture). Hand movements during object exploration were reliably classified as “exploratory procedures,” each procedure defined by its invariant and typical properties. The movement profile, i.e., the distribution of exploratory… CONTINUE READING
