Valid distinctions between conscious and unconscious perception?

Conscious and Unconscious Perception

Contrasting the properties of conscious and unconscious processes is crucial for understanding how consciousness occurs in the brain. In this chapter, we review the theoretical framework and empirical methods used to delineate and contrast conscious vs. unconscious perception. After outlining the main approaches to measure unconscious influences on brain and behavior, we describe some of the ps...

Conscious and Unconscious Perception: A Computational Theory

We propose a computational theory of consciousness and model data from three experiments in visual perception. The central idea of our theory is that the contents of consciousness correspond to temporally stable states in an interconnected network of specialized computational modules. Each module incorporates a relaxation search that is concerned with achieving semantically well-formed states. ...

Unconscious and conscious processes during visual perception.

Ongoing unconscious processes may be influenced by related conscious processes without self-awareness. (a) When the conscious semantic interpretation of physically identical shapes changes due to their angular rotation, the sequence of saccadic movements arid the localization of eye fixations over the shapes change as well. (b) The amplitude of the P 300 wave of visual evoked potentials is rela...

Dissociating perception from action during conscious and unconscious conflict adaptation.

The detection of a conflict between relevant and irrelevant information on a given trial typically results in a smaller conflict effect on the next trial. This sequential effect has been interpreted as an expression of cognitive control implemented to resolve conflict. In this context, 2 different but related issues have received increasing attention in the literature. The first issue is whethe...
