Whether an individual will engage in a specific action in a daily life depends on the perceived capabilities and the environmental factors at play (referred to as Affordance perception, which involves the perception of possibilities for action). For instance, when a car approaches, the decision to cross the road safely is influenced by factors such as the person's speed in comparison to the approaching car. We propose that the decision-making processes, known as affordance judgments, are shaped and activated by the perception of affordances and are significantly influenced by prior experiences and expected outcomes of actions.

Various tasks can lead to either overestimating or underestimating one's abilities. Mistaken decisions arising from overly cautious or overly liberal responses or from impaired perceptual sensitivity (such as after a stroke) can result in risky situations. In this talk, I will introduce a research line that aims at a stepwise development of assessments and training-approaches for judging action opportunities.
