A good hammer may not be a good poker, because what makes a tool a good hammer—having most of its mass concentrated at the distal end—makes the tool hard to control when used as a poker. Research has demonstrated that perceivers can use the haptic perceptual subsystem of dynamic touch to perceive whether a tool is suitable for performing a given task—in other words, to perceive a tool’s affordances or possibilities for action (Wagman & Carello, 2001, 2003). In four experiments I investigated perception of affordances of hockey sticks for performing power (transferring maximal force) and precision (intercepting a moving object) tasks. I manipulated the sticks’ mass distributions to vary the physical properties that made the sticks more or less well suited for power and precision actions (bottom-heavy sticks allow for greater force transfer, but are less controllable, whereas top-heavy sticks are controllable but afford less forceful hitting). Participants wielded the sticks in the absence of vision and haptically gauged the suitability of the sticks for power and precision tasks. The aims of the project were to (1) determine if perceivers could accurately and prospectively (without prior experience or feedback) judge the suitability of differently weighted sticks for power or precision tasks (Experiment I); (2) determine the effects of actually using the sticks to perform power-hitting and precision-interception actions on the same judgments (Experiments II & III); and (3) determine the role of expertise in perceiving affordances of the sticks (Experiment IV). The results supported the notion that people can use dynamic touch to accurately perceive affordances of an object, and also revealed that expertise (Experiment IV-a) and even the very limited experience and feedback obtained when novices performed the power-hitting task (Experiments II, III, & IVb) elicited sensitivity to unanticipated precision requirements inherent in hitting a hockey puck for power. In sum, the results highlight that perceivers can use dynamic touch to perceive affordances for the prospective control of behaviour and that perceptual sensitivity to action-relevant properties of objects is modifiable with experience. 2004 English text University of Cincinnati / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ucin1097535192 http://rave.ohiolink.edu/etdc/view?acc_num=ucin1097535192 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
