2.1 Input and Selective Attention What is input data? What is selective attention? What does a model of information processing look like?

Information Processing We don’t simply do skills, we make decisions according to changing environments We need to choose... Which skill to perform When to perform the skill What speed to perform the skill at Simple Model of Information processing Input Decision Making Output

Input (Display and sense organs) Display is the sporting environment where all the information is gathered from Includes both relevant and irrelevant information At a Wimbledon tennis match... Essential information includes position of opponent, speed of ball and trajectory of ball Peripheral information includes crowd and the umpire Information is collected from the display using our sense organs Vision- Tracking the flight of a ball Hearing- Hearing the call of a team mate Touch- Weighting a pass to a team mate Kinaesthetic- knowing if action feels correct Balance- Stability before a move is made

Perception Selective attention It is impossible to pay attention to all of the information which you will receive Therefore some sorting out is necessary to avoid confusion In the Perceptual mechanisms the information picked up is filtered by Selective attention Relevant information is filtered away from the irrelevant Player is then left with only important information to concentrate on. Relevant information is coded- all subsequent decisions are made on this information alone Known as the DCR process... DCR- Detection, comparison and recognition process Detection- registering the stimulus by the sense organ Comparison- referring stimulus to the memory store to be compared against stored stimuli Recognition- Finding the corresponding stimuli in the memory Decision can then be made and carried out accordingly...
