Question 1

What is cognitive psychology and when did it emerge as a field?

Accepted Answer

Cognitive psychology emerged in the mid-20th century and studies how individuals process and use information to remember, think, and understand their surroundings. This field examines the interactions among human thinking, emotion, creativity, language, and problem-solving. It arose following behaviorism's dominance, offering a new way to conceptualize the human mind by studying mental processes rather than just observable behavior.

Question 2

How did computers influence the development of cognitive psychology?

Accepted Answer

The rise of computers in the 1950s, capable of performing logical operations, offered a new model for understanding human cognition. Psychologists recognized that human mental processes might be similarly structured to computer operations. This technological advancement helped overcome limitations of behaviorism and provided a framework for studying complex cognitive processes like language acquisition and reasoning.

Question 3

What is the computer-cognition analogy proposed by Herbert Simon?

Accepted Answer

Herbert Simon compared the brain to a computer's hardware and cognition to software. Sensory systems like vision and hearing provide input, similar to data entering a computer, which is then processed by mental operations like perception and memory. This analogy helped explain how the brain processes information through distinct stages of input, processing, storage, and retrieval.

Question 4

What are the key differences between how computers and human brains process information?

Accepted Answer

While computers handle pre-coded, unambiguous information with speed and consistency, the human brain processes ambiguous sensory input from the environment. Computers excel in accuracy and rule application but lack self-awareness and consciousness. The human brain's ability to interpret ambiguous stimuli and demonstrate consciousness represents a fundamental distinction between artificial and biological information processing.

Question 5

How has artificial intelligence developed from the computer-cognition analogy?

Accepted Answer

Artificial Intelligence emerged from the computer-cognition analogy, aiming to create machines capable of intelligent behavior. AI excels in tasks requiring speed, persistence, and extensive memory, supporting fields like medical diagnosis and educational advising. The developing field of cognitive robotics seeks to equip robots with human-like, intelligent behavior, enabling them to perceive, learn, reason, and make decisions.

Question 6

Why did cognitive psychology replace behaviorism as the dominant approach?

Accepted Answer

Cognitive psychology replaced behaviorism because behaviorism focused only on observable behavior and dismissed the study of mental processes, proving inadequate for explaining complex phenomena. Psychologists recognized behaviorism's inability to account for language acquisition and other higher-order cognitive functions. The advent of computers provided a new conceptual framework that made studying internal mental processes scientifically viable.

Question 7

What cognitive processes does cognitive psychology examine?

Accepted Answer

Cognitive psychology examines how information is processed and manipulated in remembering, thinking, and knowing. It studies the interactions among human thinking, emotion, creativity, language, and problem-solving. The field investigates sensory and perceptual systems that provide input, mental operations that process information, memory storage, and response retrieval.
