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.
