Cognitive Psychology
The scientific study of mental processes and how people perceive, think, remember, and learn
What is Cognitive Psychology?
Cognitive psychology is the branch of psychology that studies mental processes including how people think, perceive, remember, and learn. Unlike behaviorism which focuses only on observable behavior, cognitive psychology examines the internal mental processes that influence behavior. It treats the mind like an information processor, similar to how a computer processes data.
Key Concepts
Attention
The cognitive process of selectively concentrating on one aspect of the environment while ignoring others. Includes selective attention, divided attention, and sustained attention.
Memory
The processes of encoding, storing, and retrieving information. Includes sensory memory, short-term (working) memory, and long-term memory systems.
Perception
How we interpret sensory information to understand our environment. Involves bottom-up processing (data-driven) and top-down processing (concept-driven).
Language
The cognitive processes involved in understanding, producing, and acquiring language, including syntax, semantics, and pragmatics.
Problem-Solving
Mental processes involved in finding solutions to problems, including algorithms, heuristics, and insight.
Decision-Making
How people make choices and judgments, including rational decision-making models and cognitive biases that affect decisions.
Major Psychologists
Ulric Neisser
Known as the "father of cognitive psychology," coined the term and wrote the foundational book "Cognitive Psychology" (1967).
George Miller
Famous for his research on short-term memory capacity, proposing the "magical number seven, plus or minus two."
Elizabeth Loftus
Pioneer in memory research, particularly false memories and the misinformation effect in eyewitness testimony.
Daniel Kahneman
Nobel Prize winner for work on judgment, decision-making, and cognitive biases (System 1 and System 2 thinking).
Real-Life Examples
Selective Attention
When you're at a crowded party but can focus on one conversation while filtering out background noise (the "cocktail party effect").
Working Memory
Remembering a phone number long enough to dial it, but forgetting it immediately after.
Confirmation Bias
Only noticing information that confirms your existing beliefs while ignoring contradictory evidence.
Schema
Your mental framework for what a "restaurant" is helps you know what to expect and how to behave when you enter one.
Applications
Education
Understanding how students learn, remember, and process information to design better teaching methods and curricula.
Therapy
Cognitive Behavioral Therapy (CBT) uses cognitive principles to help people change negative thought patterns.
User Experience Design
Applying cognitive principles to create intuitive interfaces and improve human-computer interaction.
Artificial Intelligence
Modeling human cognitive processes to develop machine learning and AI systems.
Strengths
- •Scientific and empirical approach using controlled experiments
- •Practical applications in education, therapy, and technology
- •Integrates well with neuroscience and biology
- •Explains complex mental processes that behaviorism ignored
Limitations
- •Computer analogy may oversimplify human cognition
- •Laboratory studies may lack ecological validity
- •Difficult to study internal mental processes directly
- •May underestimate the role of emotions and social factors
Summary
Cognitive psychology revolutionized the field by bringing mental processes back into scientific study. It views the mind as an information processor and uses scientific methods to understand attention, memory, perception, language, problem-solving, and decision-making.
The approach has led to practical applications in education, therapy (especially CBT), user experience design, and artificial intelligence. While it provides valuable insights into mental processes, critics note that the computer analogy may oversimplify human cognition and that laboratory studies don't always reflect real-world thinking.
