Study Notes

Knowledge Organization Through Concepts and Categories

Concepts and categories are fundamental for organizing experiences.
They allow effective interaction with the world.
Concepts are general ideas, and categories group similar items or events.

Three Ways of Categorization

Definitional Approach: Objects match a specific definition.
- Example: A "cat" has fur, likes milk, and has four legs.
- Limitation: Doesn't encompass all members of a category.
Prototype Approach: Objects are compared to a "typical" representation (prototype).
- Based on similarity to the average category member.
- High prototypicality = Close resemblance to prototype.
- Low prototypicality = Distanced resemblance.
- Example: A robin is a high prototypical bird, whereas a penguin is lower.
- Rosch (1973) introduced this idea.
Exemplar Approach: Items are compared to specific examples (exemplars) encountered before.
- New items are categorized by comparing them to existing examples.
- Useful for small categories.
- Example: Naming vehicles (e.g., car, truck, plane).

How Categories Are Organized in the Brain

Categories may be represented by specific brain areas.
Distributed representation across extensive areas.
Different brain areas might be activated for different kinds of categories
- Inferior temporal lobe (IT) may be essential for categories like "living things".
Damage to certain areas might affect categorization abilities (e.g., Warrington & Shallice, 1984).

Semantic Networks

Concepts are organized in interconnected networks.
Concepts are linked to related concepts.
Collins and Quillian (1969) proposed a model of semantic networks stored in memory.
Cognitive economy - Shared properties are stored at higher levels, reducing redundancy.

Spreading Activation

Activity in one node primes related nodes.
This model has implications for category processing.
- Information about related concepts is more quickly accessed.

Knowledge and Categorization

Expertise affects the use of categories.
Experts in a domain tend to use more specific categories than non-experts. Cultural differences influence categorization.
