Summary

The second half of the Semantic Verbal Fluency (SVF) test is more demanding, especially for older adults. Standardizing the test halves improves cognitive assessment for individuals over 50.

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Psycholinguistics

Context:

  • Semantic Verbal Fluency (SVF) tasks assess language, semantic memory, and executive functions.
  • The latter half of SVF tests increases cognitive load, particularly on working memory and lexical retrieval.
  • Understanding age-related cognitive changes is crucial for accurate neuropsychological assessment.

Purpose:

  • To pilot a standardization of the two halves of the SVF test ('animals' category).
  • To investigate age and schooling effects on SVF performance in adults over 50.
  • To establish normative data for a more nuanced interpretation of SVF test results.

Summary:

  • A pilot study standardized the Semantic Verbal Fluency (SVF) test for adults aged 50-89.

  • Significant differences were found between the first and second halves, with the second half showing higher cognitive demand.
  • Normative values were established for different age and schooling groups, accounting for working memory and executive function loads.

    • Impact:

    • Provides a refined method for assessing cognitive function in older adults.
    • Enables more accurate interpretation of SVF performance by considering intra-task difficulty.
    • Facilitates clinical application of SVF testing for improved diagnostic capabilities.
