Information Processing ModelsIn sports, we have to learn and perform a wide range of perceptual-motor skills and select the appropriate skill action for a given situation. Galligan et al. (2000)[3] identifiy how we make that skill selection through our information processing system. This system is known as the DCR process - we Detect information, Compare it with previous experiences and then React.
ModelsTwo of the better-known models which are generally referred to are Welford's (Welford 1968)[1] and Whiting's (Whiting 1969)[2]. Both models reflect the same process, although they use slightly different terminology. The process is:
Welford's ModelWelford's model suggests that we:
Sensory inputThe sensory information relevant to the situation is stored in short-term memory. The information is taken in through the senses before a decision is made in three ways. These are:
Short and long-term memoriesAll information gathered from the various sensory inputs is stored for a split second in the short-term memory before processing. It is suggested that short-term memory can only hold up to seven pieces of information and retain for less than a minute. Long-term memory, which appears to have a limitless capacity, contains information about past experiences. Decision processThe decision process occurs by comparing the current situation, held in the short-term memory, with previous experiences, held in tlong-term memory, to determine appropriate action. ActionThe action is performed regarding the movement pattern stored in long-term memory. Once the action is completed, the situation and result are stored in long-term memory for future reference. Whiting's ModelWhiting identifies three stages:
