Changes in the perception of action possibilities while climbing to fatigue on a climbing wall

Effects of a defender on run‐up velocity and ball speed when crossing a football

“…For example participants will vary judgements of affordances to account for fatigue (Pijpers, Oudejans, & Bakker, 2007) or requirements to wear ankle weights Kicking under defensive pressure S317 (Ramenzoni, Riley, Davis, Shockley, & Armstrong, 2008). These findings provide strong evidence that performers use their perception of action capabilities in realising an affordance.…”

Perception of maximum reaching height reflects impending changes in reaching ability and improvements transfer to unpracticed reaching tasks

“…Accordingly, perception reXects the action capabilities of the perceiver before the intended behavior is performed and even when action capabilities have changed over short or long time scales. In short, perception of aVordances depends on what a perceiver can do (given their action capabilities at a given moment) (e.g., Konczak et al 1992), what a perceiver has already done (e.g., Pijpers et al 2007), and what a perceiver is doing (e.g., Higuchi et al 2011). That is, perception of aVordances depends on a person's past and present states.…”

“…Perception reXects such moment-to-moment changes in action capabilities as well. For example, perception of whether a rock climbing hold can be reached depends on the climber's changing level of fatigue while climbing (Pijpers et al 2007), and perception of whether an opening can passed (or reached) through depends on whether (and how) an object attached to the body changes the dimensions of the body (or hand) (Higuchi et al 2004;Ishak et al 2008).…”

Nested prospectivity in perception: Perceived maximum reaching height reflects anticipated changes in reaching ability

“…In particular, the results show that perception of maximum reaching height was relative to actual reaching ability (i.e., was action scaled) both when the means of performing this behavior would change participants' reaching ability and when it would not (Figures 1 and 2). for a given behavior generally reflects the (new) action capabilities of the perceiver-actor even when the perceiveractor has only relatively limited exposure to such changes (e.g., Ishak et al, 2008;Pijpers et al, 2007;Regia-Corte & Wagman, 2008). The results of the present experiment build on this body of work by showing that perception of affordances for a given behavior reflects the action capabilities of the perceiver-actor both when the means of performing a given behavior would bring about (future) changes in those action capabilities and when they would not (see also Wagman & Malek, 2007).…”
