Affordances

Definition

Originally from James Gibson's ecological psychology, an affordance is what the environment offers an actor relative to that actor's action capabilities. A 6'10" rim-runner reads different lob windows than a 5'10" guard does.

Why it matters

Coaching reads is really coaching affordance perception. Players who 'see the game' are detecting and acting on affordances faster than their opponents close them.

Examples

• A back-cut affords a layup when the help defender turns their head.
• A skip pass affords a closeout opportunity when the weak-side defender shades to the ball.

Practical application

• Design practice where the relevant affordances are present and noticeable.
• Vary defenders, spacing, and timing so players learn to perceive across contexts.

Common mistakes

• Telling players what to do instead of designing for them to see it.
