Action goals influence action-specific perception

Abstract

We examined the processes that mediate the emergence of action-specific influences on perception that have recently been reported for baseball batting and golf putting (Witt, Linkenauger, Bakdash, & Proffitt, 2008;. To this end, we used a Schokokusswurfmaschine: Children threw a ball at a target, which, if hit successfully, launched a ball that the children then had to catch. In two experiments, children performed either a throwing-and-catching task or a throwing-only task, in which no ball was launched. After each task, the size of the target or of the ball was estimated. Results indicate that action-specific influences on perceived size occur for objects that are related to the end goal of the action, but not for objects that are related to intermediate action goals. These results suggest that action-specific influences on perception are contingent upon the primary action goals to be achieved.Psychonomic Bulletin & Review 2009, 16 (6), 1100-1105 doi:10.3758/PBR.16.6.1100 R.

What a car does to your perception: Distance evaluations differ from within and outside of a car

“…Apparently, this modulation of perception does not depend on the intention to overcome the judged distance. This indicates that the effect of transportation devices on perception cannot be entirely due to moment-to-moment perception of one's own potential (see e.g., Cañal-Bruland & van der Kamp, 2009;Lee et al, 2012;. Instead, the mere availability of a car modulated perception as compared to participants without a car (evidenced by the comparison of the initial distance estimations of pedestrians and drivers).…”

Coordination in Climbing: Effect of Skill, Practice and Constraints Manipulation

“…The purpose of the secondary criteria was to differentiate articles where the goal of the task was not to get to the end of the route (but, for example the task consisted of participants adopting an instructed posture). The logic behind this exclusion criteria was that previous studies have demonstrated that task goals have important impacts on skilled coordination [64,65]. Studies were recorded in separate tables.…”

Fire drill: Inattentional blindness and amnesia for the location of fire extinguishers

“…Although people may not remember the location of the nearest fire extinguisher, they can locate a bright red object when this becomes goal relevant (hopefully, in the case of a real fire). It may be that when goals become activated, people can execute action-specific programs (e.g., Cañal-Bruland & van der Kamp, 2009) that enable them to locate a previously unnoticed fire extinguisher. However, in the event of a fire, environmental and internal conditions (e.g., smoke in a hallway, anxiety, and stress), could potentially compromise perceptual and goal-relevant cognitive operations (cf., Vendetti, Knowlton, & Holyoak, 2012), such that the person would need to rely on memory to find a fire extinguisher.…”
