Document Summary
Rt is studied in highly unrealistic situations. The processing of attempting to predict the outcome of a stimulus. Strategy to reduce the time, or even the stages, of processing. Many of the stimuli we respond to daily are very predictable (ex: driving) Receptor anticipation: detects event with sensory receptors. Effector anticipation: estimate how long it would take to initiate an action. Perceptual anticipation: environmental events are predictable based on a great deal of practice. Knowing what kinds of stimuli could be presented. Participant receives advanced information about a certain feature of the movement. Goalkeeper reaction to penalty kick in soccer (experts focus on position of stance foot) Can be either long or short in duration. The average of the variable foreperiods produce shorter rt. The longer the foreperiod the shorter rt. We become increasingly expectant as the foreperiod ages. The benefit of correctly anticipating might be very small. Our current state of skills and knowledge reflects previous information processing.
