Judgments about Forces in Described Interactions between Objects
White, Peter A.
Journal of Experimental Psychology: Learning, Memory, and Cognition, v37 n4 p979-993 Jul 2011
In 4 experiments, participants made judgments about forces exerted and resistances put up by objects involved in described interactions. Two competing hypotheses were tested: (1) that judgments are derived from the same knowledge base that is thought to be the source of perceptual impressions of forces that occur with visual stimuli, and (2) that judgments are generated using simple models or heuristics for deriving force judgments from kinematic information. The results show some similarities with perceptual impression research, particularly that an active object is judged to exert more force on an inactive object than the latter exerts on the former. However, most of the available kinematic information had little or no effect on judgment, supporting the hypothesis that force judgments are generated according to simple rules. Presentation of information about damage to the objects resulted in use of all available kinds of information; this could reflect greater imageability of damage information than kinematic information.
