Study Notes

Knowledge

Knowledge is defined as your understanding of a particular thing or event; a unit of information within semantic memory.
A category is a group of related concepts in semantic memory.
Examples of categories include dining room chairs and living room chairs.
Categorization is the process of sorting new information into existing categories.
Categories help with recognizing objects more quickly and accurately.
Categories allow us to disregard the variations amongst individual objects.
Categorization reduces the amount of continual learning needed based on individual items.

How Categorization is Studied

Definitional Approach: Identifying minimal criteria necessary to classify an object within a category.
- Example: A plane requires an engine and wings to fly.
Family Resemblance: Objects in a category share many characteristics but not each characteristic.
- Example: Members of the "bird" category differ but have some overlapping similarity, such as having wings.
Prototype Approach: New objects are compared to prototypes (ideal/typical examples) within a category. The best match is used to classify the object.
- Example: A robin might be the prototype for the "bird" category.

Rosch (1975)

A prototype is the typical/average example of a given category.
Prototypes are generally not actual members of the category.
Prototypes are continuously updated as new examples are encountered.

Hierarchical Organization of Categories (Rosch et al., 1976)

Categories are organized hierarchically, with levels based on general to specific.
Superordinate (Global) level: Broad categories; example; "furniture."
Basic level: Mid-level categories; example; "chair."
Subordinate (Specific) level: Narrow, more specialized categories; example; "dining room chair.”

The Basic Level Advantage (Rosch et al., 1976)

Categorization typically starts at the basic (mid-level) category.
Studies have shown basic-level categories are verified quicker than superordinate or subordinate categories.
Subjects tend to name objects using basic-level names in tasks where categorizing items by describing them is required.
Typicality of objects within a category also influences the categorization process.

Tanaka & Taylor (1991)

Experts use subordinate-level names when describing objects in categories (such as bird experts using robin)
Non-experts tend to use basic-level names (such as simply saying "bird")

Spreading Activation Model (Collins & Loftus, 1975)

Activation of one concept initiates spreading activation amongst related concepts.
Short links/connections indicate stronger relationships than longer ones amongst concepts.
The amount of activation spreading/flowing to another concept is affected by the number of links/connections present.

Priming and Spreading Activation

Priming occurs when exposure to one object or idea influences the processing of a related object or idea later on.
Repetition Priming: If an item is processed more than once, subsequent processing is easier/faster.
Associative Priming: Processing an item is easier/faster if a related item was previously processed.
Specific examples of how items being associated influence how quickly responses are generated in priming exercises are also presented.

Testing the Hierarchical Model

Studies often used sentences to verify items belonging to specific categories; such as, if "a Canary is a bird?" or if "A canary is a fish?"
Retrieval/processing time is dependent on the number of connections needed to determine whether an item belongs to a certain category.

Neural Network Models

Concepts are represented by patterns of activity across interconnected nodes.
Activation spreading from one concept to another concept is how associations amongst various concepts are created.
