  • Title: Action-specific perception of speed is independent of attention.
    Author: Witt JK, Sugovic M, Dodd MD.
    Journal: Atten Percept Psychophys; 2016 Apr; 78(3):880-90. PubMed ID: 26758975.
    Abstract:
    According to the action-specific account of perception, a perceiver's ability to act influences how the environment is perceived. For example, in a computer-based task, participants perceive fish as moving faster when they use a smaller net, and are thus less effective at catching the fish (Witt & Sugovic, 2013a). Here, we examined the degree to which attention may influence perceptual judgments by requiring participants to engage in a secondary task that directed their attention either toward (Exp. 1) or away from (Exp. 2) the to-be-caught fish. Though perceived fish speed was influenced by participants' catching performance-replicating previous results-attentional allocation did not impact this relationship between catching performance and perceived fish speed. The present results suggest that action directly influences spatial perception, rather than exerting indirect effects via attentional processes.
