Cognitive Psychology
Explore how the mind processes information, including attention, memory, language, problem-solving, and decision-making.
1Introduction
Reading a book while ignoring background noise, recognizing a friend in a crowd, solving a puzzle — all involve cognitive processes.
Cognitive psychology studies mental processes: how people perceive, remember, think, speak, and solve problems.
2Key Concepts
Information Processing
Mind as computer: input, processing, output.
Schema
Mental framework for organizing knowledge.
3Attention
Selective attention: Focusing on one input while ignoring others. Broadbents Filter Model: Early selection based on physical characteristics.
Inattentional Blindness
Failure to notice unexpected object when attention is engaged on another task (e.g., invisible gorilla study).
4Memory & Cognition
Working memory: Active processing of limited information. Long-term memory: Virtually unlimited storage. Baddeleys model: Central executive, phonological loop, visuospatial sketchpad, episodic buffer.
5Language
Sapir-Whorf Hypothesis: Language influences thought (linguistic relativity). Chomskys Universal Grammar: Innate language acquisition device.
6Problem-Solving
Functional Fixedness
Cannot see alternative uses for objects.
Mental Set
Tendency to use familiar strategies.
Algorithms
Step-by-step guaranteed solution.
Heuristics
Mental shortcuts, not guaranteed.
7Decision-Making
Availability Heuristic
Judge by ease of recall.
Representativeness
Judge by typicality.
Anchoring
Rely on first piece of info.
Framing
Influenced by how info is presented.
Frequently Asked Questions
- What is the information processing approach?
- The information processing approach views cognition as a series of computational steps, similar to how a computer processes data through input, storage, and output.
- What is the difference between attention and perception?
- Attention is the process of focusing cognitive resources on specific information. Perception is the process of organizing and interpreting sensory information.
- What are heuristics and how do they affect decision-making?
- Heuristics are mental shortcuts or rules of thumb that allow people to make decisions quickly. While efficient, they can lead to biases (e.g., availability heuristic, representativeness heuristic).
- What is the Sapir-Whorf Hypothesis?
- The Sapir-Whorf Hypothesis proposes that language influences or determines the way we think (linguistic relativity).
- What is functional fixedness?
- Functional fixedness is the inability to see an object as having a function other than its typical use, a problem-solving obstacle.

Study Tips
- Connect to memory: Cognitive psychology builds on memory research.
- Understand attention limits: We cannot attend to everything simultaneously.
- Know the heuristics: Understand how they lead to biases.
- Apply to real life: Notice cognitive processes in daily decisions.
