Perceiving the Affordances of Others
Humans have the ability to perceive the action opportunities available to others. Research has shown that we are adept at picking up affordances for ourselves, but can we do the same for others? Two competing views on this matter are the mental simulation approach and the ecological view. The mental simulation approach suggests that we perceive the affordances of others by mentally simulating how we would perform the same action ourselves, while the ecological view proposes that we directly pick up information from the environment to determine the action capacities of others. A study by Raman Zoni et al. compared these approaches and found that participants were accurate in judging the maximum reach height for another person, even when the person's action capabilities were very different. This supports the idea that information about others' actions is specified in the optic array, providing evidence for direct perception of affordances rather than mental simulation.
Influence of Kinematic Information on Affordance Perception
Kinematic information plays a role in perceiving the affordances of others. A study by Wiest and colleagues investigated the influence of kinematic information on perceiving maximum reach height while jumping and horizontal long-jumping distance. Point-light videos were used to capture movement kinematics, and participants had to make judgments about the affordances based on these videos. The results showed that judgments were more accurate after viewing movements related to the targeted affordances (e.g., squatting and walking) compared to movements unrelated to these affordances (e.g., balancing and twisting). Additionally, the study found that athletes, particularly basketball players, were superior to non-athletes in perceiving jumping-related affordances, suggesting an attunement to kinematic information based on sports-specific experience.
Perceiving Nested Affordances and Memory Effects
Humans can perceive nested affordances in others, not just their current action capabilities, but also impending changes in those capabilities. Studies have shown that we can pick up direct information from the environment to detect the nested affordances of others. For example, perceiving whether someone can reach an object while standing on a stool or using a stick as an extension of their arm. Furthermore, research suggests that perceived affordances for others are continuous processes and not just limited to present moments. In a study by Wagman and colleagues, participants accurately judged both the present and remembered affordances of others, supporting the concept of perception and memory as continuous processes. These findings have implications for understanding the role of memory in the ecological approach to skill and the assessment of athletes based on nested affordances.
How well can we perceive the action opportunities available to others? What information do we use? Can we perceive nested affordances – that is, be sensitive to not only another person’s action capabilities but impending changes in their capabilities? Some implications for coaching.
