Describe information processing through the Welford’s model, outline sensory input, and explain the signal-detection process.

Simple model of Information Processing

CNS

This is the central nervous system: brain and spinal cord and the reactions taken to make movements possible

Output

What the performar did Ex: Tennis player What shot they played in order to return the ball to the other court and wheter or not it was successful This is the response

Input

The enviornment that the performer can see, hear, and feel It is sometimes called the display of the stimuli

Feedback

Welford's Model (1968)

Sense Organs

Perception

Short-Term Memory

Long-Term Memory

Decision Making

Interoceptors

-Provide information from within the body -Information about body position and the position of limbs -The main interoceptors involved in sport are the vestibular apparatus, which provides information about balance; and joint receptors, muscle spindles and Golgi tendon organs, which provide information about limb positions

-Provide information from outside the body -The main exteroceptors involved in sensation with regard to the sport are vision and audition

Exteroceptors

‘-Sense of self’ -In the limbs, the proprioceptors are sensors that provide information about joint angle, muscle length, and muscle tension -Which is integrated to give information about the position of the limb in space

Proprioceptors

DCR: Detection-Comparison-Recognition

Individuals receive over 100,000 pieces of information per second This may be information from the environment and/or from within the person themselves
