Processing category terms in context: instantiation and the structure of semantic categories
Summary
Readers do not automatically encode category terms as specific examples. Instead, processing category terms activates general summary representations, influencing how information is stored and retrieved.
Area of Science:
- Cognitive Psychology
- Psycholinguistics
- Semantics
Background:
- Previous research suggested semantic categories are encoded as specific exemplars.
- The role of context in biasing encoding towards typical or atypical exemplars was explored.
Purpose of the Study:
- To investigate whether semantic categories in context are encoded as particular exemplars.
- To differentiate between encoding and retrieval processes influencing semantic memory.
- To examine the routine nature of assigning referents to category terms during sentence processing.
Main Methods:
- Experiment 1: Cued-recall task with sentences biased towards atypical exemplars.
- Experiment 2: Modified Stroop paradigm to assess semantic interference at encoding or retrieval.
- Experiment 3: Controlled for encoding strategy differences between tasks.
Main Results:
- Atypical exemplars were better retrieval cues when context biased towards them (Experiment 1).
- Semantic interference patterns in the Stroop task contradicted routine exemplar encoding (Experiment 2).
- No significant interference occurred for atypical exemplars, suggesting they are not routinely encoded (Experiment 2).
Conclusions:
- Assigning a specific referent to a category term is not a routine part of sentence encoding.
- Processing category terms primarily involves activating summary representations rather than specific instances.
