This study reveals how the brain processes different types of knowledge. Semantic memory involves both stored knowledge and dynamic interpretation processes, influenced by the task and knowledge category.

Area of Science:

  • Cognitive Neuroscience
  • Neuroimaging
  • Psychology

Background:

  • Limited research exists on the cognitive processes underlying semantic memory.
  • Previous studies focused on neural representations of specific knowledge categories, neglecting semantic interpretation processes.

Purpose of the Study:

  • To investigate the neural correlates of semantic processes in semantic memory.
  • To examine how different knowledge categories (natural kinds, artifacts, abstract concepts) are processed during typicality and pleasantness judgments.

Main Methods:

  • Functional magnetic resonance imaging (fMRI) was used to monitor regional cortical activity.
  • Healthy young adults performed typicality and pleasantness judgments on visual stimuli of natural kind, artifact, and abstract nouns.

Main Results:

  • A significant interaction was found between knowledge category and judgment type.
  • Typicality judgments showed greater temporal-occipital activation compared to pleasantness judgments across all categories.
  • Pleasantness judgments elicited distinct anatomical activations for each semantic category when contrasted with typicality judgments.

Conclusions:

  • Semantic memory is characterized by a dynamic interplay between semantic knowledge and flexible interpretation processes.
  • The brain utilizes distinct neural pathways for interpreting knowledge based on the specific semantic task and category involved.
