Individual differences in working memory capacity influence how people process sentences, affecting their ability to resolve retrieval interference during comprehension.
Area of Science:
- Cognitive Psychology
- Psycholinguistics
- Neuroscience
Background:
- Sentence comprehension relies on complex working memory processes.
- Retrieval interference occurs when similar sentence elements compete for access.
- Understanding individual differences in interference effects can illuminate working memory architecture.
Purpose of the Study:
- To investigate how individual differences in working memory capacity relate to sensitivity to retrieval interference during sentence processing.
- To examine the roles of syntactic and semantic interference in both online and offline sentence comprehension.
- To explore the relationship between working memory, short-term memory, vocabulary, and executive functions in resolving interference.
Main Methods:
- Individual differences in sensitivity to syntactic and semantic interference were measured during sentence comprehension tasks (self-paced reading, comprehension questions).
- Participants completed working memory, short-term memory, vocabulary, and executive function assessments.
- Statistical analyses examined the predictive power of working memory and other cognitive abilities on interference effects.
Main Results:
- General working memory capacity predicted syntactic interference during online sentence comprehension, independent of vocabulary.
- Working memory and vocabulary knowledge interacted to influence semantic interference resolution in offline comprehension accuracy.
- Semantic short-term memory capacity predicted reaction times for comprehension questions, specifically for semantic interference.
Conclusions:
- Working memory capacity and semantic knowledge play distinct but interacting roles in resolving retrieval interference during sentence comprehension.
- Existing theoretical models of working memory and sentence processing require refinement to account for these findings.
- Future research should focus on reconciling different theoretical perspectives to better understand the working memory system.

Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
