This study found that speaking and writing productivity varied by task, while efficiency depended on expression mode. Discourse coherence remained consistent across conditions and was unrelated to verbal working memory.

Area of Science:

  • Linguistics
  • Cognitive Psychology
  • Speech and Language Pathology

Background:

  • Understanding discourse patterns in oral and written communication is crucial for assessing language abilities.
  • Investigating factors influencing language production, such as task type and cognitive load, informs clinical practice.
  • Verbal working memory plays a role in language processing, but its specific impact on discourse measures needs further clarification.

Purpose of the Study:

  • To examine how mode of expression (speaking vs. writing) and task type (picture description vs. personal narrative) affect discourse productivity, efficiency, and coherence.
  • To determine the relationship between these discourse measures and individual differences in verbal working memory capacity.
  • To explore the clinical utility of discourse analysis in evaluating language skills in young adults.

Main Methods:

  • Twenty-five college students produced spoken and written samples via picture description and personal narrative tasks.
  • Discourse samples were analyzed for productivity (e.g., utterance length), efficiency (e.g., speed of production), and coherence.
  • Performance measures were correlated with scores from verbal working memory tests.

Main Results:

  • Productivity was significantly influenced by the elicitation task but not by verbal working memory.
  • Efficiency was affected by the mode of expression (oral vs. written) and showed a weak correlation with verbal working memory.
  • Coherence was not significantly influenced by task type, mode of expression, or sample length, and was unrelated to verbal working memory.

Conclusions:

  • Discourse productivity and efficiency are sensitive to task demands and mode of expression, suggesting these factors should be considered in clinical assessments.
  • Coherence appears to be a robust measure, less affected by situational variables, but its relationship with cognitive capacity warrants further investigation.
  • The findings suggest that specific discourse measures may have differential clinical utility, highlighting the need for tailored assessment approaches.
