James J Gibson II, contributor to the study of perception and action, discusses affordance theory and its application to sports. He explores how perceptual information is transformed into action, the direct perception of values and meanings in the environment, and the concept of affordances in relation to an animal's environment. He also highlights the effectiveness of changing constraints in sports and the importance of designing practice activities that align with the game's affordances.

Quick takeaways
Perception of the environment is based on the opportunities for action that surfaces and objects provide, rather than physical properties like size or distance.
Affordances are dynamic and context-dependent, changing in response to actions and taking into account individual differences in action capabilities.
Deep dives
Gibson's Theory of Affordances
Gibson's theory of affordances suggests that our perception of the environment is not solely based on physical properties, but rather on the opportunities for action that surfaces and objects provide. This means that instead of perceiving objects in terms of their size, distance, or speed, we perceive their potential for action, such as the ability to catch a ball or navigate through a gap. Gibson argues against the need for higher cognitive processing to interpret perceptual information and instead proposes that affordances can be directly perceived based on the information present in the environment, without requiring mental models or internal representations.
Dynamic Nature of Affordances
Affordances are not fixed properties, but rather dynamic and context-dependent. They can change rapidly in response to actions of both the individual and the environment. For example, a pass that was once available may no longer be possible if a defender moves into the passing lane. Affordances also vary depending on the action capabilities of the perceiver, taking into account factors such as anatomical and skill differences. Understanding affordances allows performers to creatively adapt their behavior, prospectively control their actions, and make decisions based on action possibilities rather than relying solely on physical properties.
Implications for Coaching
Using affordance theory in coaching provides a practical framework for understanding decision-making in sports. Instead of trying to infer mental processes, coaches can focus on manipulating environmental constraints and shaping athletes' action capabilities through training. By designing practice activities that align with affordances, coaches can educate athletes' attention to the information needed to control the action itself. Additionally, thinking about task difficulty in terms of affordances allows coaches to tailor practice activities to the skill level and age of the athletes, ensuring appropriate challenges. Affordance-based practice design promotes skill acquisition, decision-making, and performance in sports.
