On the interaction of attention and awareness in visual processing
Zusammenfassung der Projektergebnisse
When observers were asked to report the motion direction of a stimulus composed of two components, of which one was less visible than the other, (a) perception and eye movement responses were dissociated, and (b) both responses were influenced by feature-based visual attention. Specifically, observers’ eye movements were driven by a motion signal that did not produce a corresponding conscious percept – they moved their eyes in one motion direction while consciously perceiving another, indicating a potential dissociation of the neuronal processing signals driving perception and action. For both perception and action, attention helped rendering an almost invisible stimulus more visible. These findings advance our understanding of the interaction between perception, action, attention and awareness, and can potentially have implications for clinical studies in patients with disorders in perception, motor behaviour such as eye movements, and attention.
