Perceiving Action-Relevant Properties of Tools through Dynamic Touch: Effects of Mass Distribution, Exploration Style, and Intention
Harrison, Steven J.; Hajnal, Alen; Lopresti-Goodman, Stacy; Isenhower, Robert W.; Kinsella-Shaw, J. M.
Journal of Experimental Psychology: Human Perception and Performance, v37 n1 p193-206 Feb 2011
At issue in the present series of experiments was the ability to prospectively perceive the action-relevant properties of hand-held tools by means of dynamic touch. In Experiment 1, participants judged object move-ability. In Experiment 2, participants judged how difficult an object would be to hold if held horizontally, and in Experiments 3 and 4, participants rated how fast objects could be rotated. In each experiment, the first and second moments of mass distribution of the objects were systematically varied. Manipulations of wielding speed and orientation during restricted exploration revealed perception to be constrained by (a) the moments of mass distribution of the hand-tool system, (b) the qualities of exploratory wielding movements, and (c) the intention to perceive each specific property. The results are considered in the context of the ecological theory of dynamic touch. Implications for accounts of the informational basis of dynamic touch and for the development of a theory of haptically perceiving the affordance properties of tools are discussed.
