“…Similarly, after adapting to optic flow that is too slow, when attempting to walk in place (i.e., with no forward movement), participants end up drifting forward by half a meter. Recalibration to the relationship between walking speed and optic flow speed occurs after just a few minutes of exposure and predicts the outcomes of subsequent actions, including walking, throwing, and kicking (Bruggeman, Pick, & Rieser, 2005;Bruggeman & Warren, 2010;Bruggeman, Zosh, & Warren, 2007;Rieser et al, 1995).…”

The action-specific account of spatial perception asserts that a perceiver's ability to perform an action, such as hitting a softball or walking up a hill, impacts the visual perception of the target object. Although much evidence is consistent with this claim, the evidence has been challenged as to whether perception is truly impacted, as opposed to the responses themselves. These challenges have recently been organized as six pitfalls that provide a framework with which to evaluate the empirical evidence. Four case studies of actionspecific effects are offered as evidence that meets the framework's high bar, and thus that demonstrates genuine perceptual effects. That action influences spatial perception is evidence that perceptual and action-related processes are intricately and bidirectionally linked.Keywords Embodied cognition . Spatial cognition . Visual perception . Action-specific perception No vision scientist would deny that a primary purpose of vision is action. But how vision best serves action has been continuously debated. For some, visual perception best serves action by being as geometrically accurate as possible. Given ambiguities in the visual information, the visual system makes underlying assumptions (known as priors or natural constraints) and unconscious inferences based on statistical regularities of the environment. These approaches fall under constructivist accounts. Action's role in constructivist approaches is primarily limited to being a motivation for why perception needs to achieve constancy (so that visual information can be successfully transformed into motor coordinates), but is not itself considered to be an influence for perception.Even for approaches to vision that place a greater emphasis on action, its role is limited. According to the ecological account, perception best serves action by being faithful to the visual information, without being supplemented with extraneous ideas (Gibson, 1979; see Witt & Riley, 2014, for extended discussion on the discrepencies between ecological and action-specific approaches). In situations in which the visual information is ambiguous, the perceiver can simply move around the object to accumulate more information until the information is unambiguous. For ecological accounts, action's role is relevant in gathering the necessary visual information, and action drives perception to actively select the information that is relevant for action, but action does not provide direct information for perception. As another example of an account that purportedly emphasizes action, the theory of two visual streams emphasizes both perception and action (Milner & Goodale, 1995). However, even this theory divorces perception from action by considering the two to be subserved by anatomically different pathways. Indeed, such theories refer to the ventral pathway as "vision for perception" and the dorsal pathway as "vision for action." Given that the processing in the dorsal stream is thought to be unconscious (Milner & Goodale, 2008), this theory emphas...

“…They learn how the forces and directions of their actions map onto visible and audible results and then act on the learned mappings when they cannot see or hear. Skillful action depends on the calibrations being fine-tuned to take into account variations in the environmental conditions, for example, adjusting the force and amount of walking (Rieser et al, 1995), the direction of walking (Pick, Rieser, & Wagner, 1999), the force and direction of throwing (Bruggeman, Pick, & Rieser, 2005;Bruggeman, Piuneau, Rieser, & Pick, 2009;Rieser et al, 1995), and the loudness of singing (Siegel & Pick, 1974).…”

“…Research shows that the learned recalibrations transfer readily to different forms of the same action. For example, recalibration of forward walking transfers to different speeds and forms of locomotion (Rieser et al, 1995;Withagen & Michaels, 2002), recalibration of throwing transfers to different speeds and directions of hurling a ball (Bruggeman et al, 2005;Rieser et al, 1995), and recalibration of the loudness of speaking transfers to different amplitudes of speaking (Pick & Siegel, 1989).…”

“…It is widely recognized that adaptation to changes in the dynamics of the body and environment plays a crucial role in the acquisition and execution of skills such as reaching (Lackner & Dizio, 1994;Shadmehr & Mussa-Ivaldi, 1994;Shadmehr & Wise, 2005), throwing (Bruggeman, Pick, & Rieser, 2005), and walking (Bruggeman, Zosh, & Warren, 2007;Choi & Bastian, 2007;Gordon & Ferris, 2007). Factors such as growth, fatigue, and tool use can significantly alter the limb movements that result from a particular pattern of muscle forces.…”

Learning novel mappings from optic flow to the control of action

Many perceptual-motor skills can be captured in terms of mappings from information in sensory arrays to movements of the body, but little is known about how these mappings are acquired and updated. The present study demonstrates that people adapt to changes in the dynamics of a controlled system by learning novel mappings from information in optic flow to movement of the system. Two groups of subjects performed a simulated braking task, using a foot pedal to decelerate to a stop at a target. Brake dynamics were manipulated such that deceleration was proportional to pedal position for one group, and both pedal position and current speed for the other group. Both groups adapted to their respective brake dynamics by learning to use different combinations of optic flow field variables, revealing a form of adaptation that has not been previously reported, but likely plays a critical role in robust visuomotor control.
