Fun Fact: Did you know that we receive over 100,000 pieces of information per second? And most of it is considered "noise"!

Welford's model overview

  • Developed by AT Welford in 1968, this model explains what happens in the Central Nervous System (CNS) when processing information.
  • Note: While Welford presents his model linearly, many of the processes occur simultaneously.

Sensation of senses

  • Our senses relay information from our environment to the brain.
  • This information is interpreted based on past experiences and is stored in the Long-Term Memory (LTM).
  • Senses can be divided into two categories: exteroceptors and interoceptors.
  • Exteroceptors provide information from outside the body, mainly through vision and audition (hearing).
  • Interoceptors provide information from within the body, like body position and limb positions.
  • Key interoceptors in sports are the vestibular apparatus (balance) and joint receptors, muscle spindles, and Golgi tendon organs (limb positions).

Example: When a soccer player sees the ball coming, their exteroceptors (vision) send that information to their brain. Meanwhile, their interoceptors help them sense their body's position and help them move accordingly to kick the ball.
