1. AS Level – Week 21 Theory Module 1 Information Processing Whiting & Welford

2. Information Processing Welford’s Model Copy diagram from the board. Welford’s model represents the major stages in Whiting’s model but is more detailed. Hot Tip You must be able to explain how the information is used and the processes that are involved in producing a motor programme.

3. Input – (sense organs & internal sensors), the information is gathered via the sensory system and the perceptual mechanism interprets the stimuli. Perception – involves 3 stages (DCR process) Perception – involves 3 stages (DCR process) 1. detection – the identification of the stimulus 2. comparison – the gathered stimuli are compared to memory stores 3. recognition – the stimuli is matched to one stored in the memory. Memory – (short-term store & long-term store) involves the gathered information being interpreted and compared to past experiences before a decision is made. The process involves the short-term sensory stores, short-term memory and long term memory. Memory – (short-term store & long-term store) involves the gathered information being interpreted and compared to past experiences before a decision is made. The process involves the short-term sensory stores, short-term memory and long term memory. Decision-making – involves the formulation of a motor programme most appropriate to the current situation. This is also known as the translatory mechanism. Decision-making – involves the formulation of a motor programme most appropriate to the current situation.

4. Effector control – the selected motor programme or schema is sent via the body’s nervous system to the muscular system (effectors) allowing movement to occur. Effector control – the selected motor programme or schema is sent via the body’s nervous system to the muscular system (effectors) allowing movement to occur. Feedback – once the action has been initiated, the performer gathers information about the effectiveness of the motor programme, either internally or externally, allowing modifications to be made.
