Cognitive science is the interdisciplinary study of mind and intelligence.
Challenges to the computational/representational view can be met by expanding and supplementing it to take into account the importance of consciousness, emotions, embodiment, social relations, and dynamic systems.
Reject reductionism (only one fundemental level of explanation) and anti-reductionism (higher levels are autonomous).
I propose multilevelism. This view takes seriously the fact that operation at different levels of understanding with different methodologies is essential to understand nature of mind. But these levels and methods are not independent of each other: the strength of cognitive science depends on integration of them.
|Molecular biology||Biochemical experiments and genetic models|
|Neuroscience||Experiments and computational models|
|Distributed representations and processing||Connectionist models, psychological experiments|
|Symbol processing||Symbolic AI models, psychological experiments|
|Societies||Sociology, distributed AI, social epistemology, social psychology|
Example 1: multilevel approach to consciousness:
Example 2: multilevel approach to creativity:
Work at every level should appreciate of work at other levels, particularly those directly above and below it. No level is immune from revision, although no level is expected to be wiped out from above or below.
Advice to students and researchers:
Pick the level and method that interests you most and best suits your capabilities, and pursue them cooperatively with others working at different levels. Stay aware of implications of cognitive science for design, intelligent systems, human-machine interaction, and education.
Some open questions
1. How do neural networks in human brains produce rule-based, concept-based, analogical, and imagistic thinking?
2. How do emotion and cognition interact to produce intelligence?
3. How does consciousness emerge from neural activity?
4. How does brain chemistry contribute to intelligence?
1. How can cognitive science help to improve learning and teaching?
2. How can more intelligent robots be developed?
3. How can intelligent computer systems enhance human performance?
4. How can cognitive science contribute to more interesting games by modeling more realistic opponents?
5. How can health, intelligence, and happiness be increased by neurochemical interventions?
1. If brain scans can help to identify psychopaths and others likely to commit crimes, should they be used?
2. If cognitive science contributes to the development of artificial intelligence, would this make people obsolete?
3. Should there be limits on drug modifications of brain activity?
4. Is free will an illusion?
