Abstract |
The main obstacles to the scientific study of consciousness are its subjectivity and its complexity. Object perception and recognition (OPR) can be a useful model in such a study because there is a remarkable agreement between the subjective and objective aspects of OPR; in addition, while OPR is somewhat simpler than other forms of cognition, it adequately represents one characteristic feature of consciousness: intentionality. It thus allows convergent studies of experimental psychology, artificial intelligence and biology, in both humans and animals. Recent advances in the neurophysiology of visual OPR in subhuman primates and its brain imaging in humans provide a vital thread to the neural basis of consciousness, especially of its integrative, unifying character. |
