| dcterms.abstract | Growing evidence from behavioral and neurological studies of action perception indicates that the cognitive system partly supports action based on afforded features, even when the observer does not intend to act. This perception-action coupling system, known as affordance perception, is commonly explored using Stimulus-Response Compatibility (SRC) paradigms. This dissertation used the SRC paradigm to explore how affordance perception can be modulated in various experimental contexts. Specifically, this dissertation aimed to investigate three key aspects: (i) the effects of affordance perception on oculomotor behaviors, specifically its impact on search performance for categorically related objects, (ii) the interaction of affordance perception with the observer’s motor experience when discriminating faces of renowned athletes, and (iii) the modulation of affordance perception across different stimulus presentations, affording increasing levels of visual dimensions. The first study assessed the degree to which categorically related objects that do not include any explicit action are still afforded by semantic congruence, and how affordance might facilitate visual search when responding with the matching response effector. Findings indicated that affordance extends beyond simple object recognition, consistently influencing performance in a change blindness flicker paradigm based on the afforded response effector and the types of changes the target underwent. This demonstrates that affordance perception significantly impacts complex visual tasks, such as detecting changes beyond basic object recognition. The second study explored whether the presentation of well-known athlete (e.g., renowned soccer player) leads to an affordance effect when using a compatible (foot pedal) response. This idea rests on the concept that knowledge of another person’s highly practiced actions activates similar motor system actions in the observer. Both novice and elite (NCAA) athletes viewed renowned athletes in action or nonaction settings to determine how knowledge and athletic expertise influence affordance perception. Results showed that motor expertise significantly modulates affordance perception, as demonstrated by the reduced social contrast effect in elite athletes. This highlights the dynamic nature of affordance, shaped by individual differences in expertise and skill. The final study extended these findings by exploring how different visual presentations influence behavior and advancing methodological approaches in affordance perception research. Affordance perception was compared across two modes of stimulus presentation: computer-based 2D and virtual reality (VR). It was hypothesized that VR, with its higher ecological validity and immersive environment, would enhance cognitive performance. The findings showed that VR presentations led to faster reaction times and more pronounced affordance effects, likely due to the increased depth cues and realism of 3D stimuli. However, the higher error rates in VR also indicate greater task difficulty, suggesting the need for further investigation into the factors contributing to these effects. Together, this dissertation provides novel behavioral evidence that affordance can be modulated by categorical and contextual information and task demands, with the observer’s semantic knowledge, embodied experience, and modes of visual presentation influencing perception-action coupling. | |
