In the two-component model of goal-directed aiming (Woodworth, 1899), the kinematic events during the initial portions of the movement reflect movement planning toward the target, while later kinematic events reflect the processing of sensory feedback during the corrective process. The location of peak velocity has been associated with the separation point between the initial, planned portion of the movement and the latter, feedback-based portion of the movement (e.g., Elliott, Binsted, & ...
Elliott and Khan contend that there are two types of visual regulation associated with goal-directed movement. We also looked to see whether this Müller-Lyer type of perturbation resulted in a discrete adjustment to the limb movement late in the trajectory, which is the result consistent with the notion of late regulation based on limb and target information (e.g., Elliott et al. It is certainly clear that goal-directed limb movement consists of two different phases—an initial movement phase...

Although the human visual system can provide accurate object-related information from retinal input alone (i.e., when the eyes are fixated), when an object of interest moves relative to the retina, either because the self or the object is moving, our normal response is to move the eyes and head in an attempt to maintain the object image on the fovea. We then turn to the use of these eye movements in tracking smooth object motion as opposed to step changes in object position that elicit ...
After providing background information about the importance of visual feedback throughout practice, this chapter explores issues related to the use of multisensory information, attentional processes, individual differences, mental practice, and the amount of practice related to skill acquisition. For instance, some motor control models propose that visual information is important during the execution of even very rapid movements (e.g., Elliott et al. Conversely, determining how sensory ...
Almost 10 years before Paul Fitts published his landmark work formalizing the speed–accuracy trade-off for aiming movements, he was developing the genesis of this model with work targeted at the commendable goal of stopping airplanes from falling from the sky (Fitts & Jones, 1947; Fitts, Jones, & Milton, 1950). We begin with an overview of applied motor behavior research, with an emphasis on human performance psychology, and examine how that research gave rise to the modern discipline of ...
With the 2012 London Games officially less than a year away, expect to start seeing more and more Olympic athletes signing endorsement deals. To mark the year-out milestone to the London 2012 Olympic Games, Citi, an official sponsor of the 2012 U.S. Olympic and Paralympic Teams and the U.S. Olympic Committee, last week held a ceremonial Citi Team USA flag-raising event outside the Citibank Financial Center at its headquarters in New York City. Olympic silver medalist Alicia Sacramone (...
