Flashcards

Hixon Symposium (1948)

A pivotal conference in 1948 that marked the beginning of cognitive psychology, focusing on the comparison between the mind and information-processing machines. It challenged the dominance of behaviorism by suggesting that mental processes could be studied scientifically.

Information-processing model

A model of cognition that views the mind as a system that processes information in stages, similar to how computers work. This approach focuses on how information is received, processed, stored, and retrieved.

Nativist Perspective

A theoretical view in cognitive psychology that assumes some cognitive abilities are innate or pre-wired, not learned. It emphasizes the role of biological factors in shaping cognition.

Associationist Perspective

A theoretical view in cognitive psychology that emphasizes the role of experience and learning in shaping cognition. It suggests that mental processes are formed through associations formed through repeated experiences.
