Study Notes
Graded Category Structure and Similarity Relations in Cognitive Psychology
- Hampton (1979) developed the Polymorphous Concept Model, which uses featural overlap to measure graded category structure.
- Familiarity and typicality are key factors in graded category structure, according to Ashcraft (1978) and McClosky (1980).
- Hampton (1983) collected data for 12 categories and found high inter-correlations between typicality, generation frequency, and familiarity.
- Variables such as age of acquisition, word frequency, and imageability do not contribute to category structure.
- Graded category structure is due to similarity relations between category members, reflected in typicality, generation frequency, response time, and family resemblance.
- Family resemblance and similarity are interconnected, with categories bound by their similarity to each other.
- Similarity data can be collected through various procedures such as pair-wise ratings and card-sorting tasks.
- Multi-dimensional scaling (MDS) provides a visual representation of similarity relations between objects or entities.
- The contrast model calculates similarity between exemplars based on common features and differences.
- MDS of similarity data reflects the structure of categories and can highlight differences in mental representations between groups of people.
- Graded category structure measures such as typicality and generation frequency reflect the similarity structure of categories, as shown in MDS representations.
- Criticisms of similarity include its inflexibility and failure to account for semantic representations based on richer data.
