Providing contextual knowledge significantly improves reading efficiency, especially for individuals with lower working memory (WM) capacity. This benefit is more pronounced under conditions of increased age and attentional demand.

Area of Science:

  • Cognitive Psychology
  • Human Development
  • Educational Psychology

Background:

  • Working memory (WM) capacity influences reading comprehension.
  • Age and attentional demands can impact cognitive performance.
  • Contextual knowledge is hypothesized to aid information processing.

Purpose of the Study:

  • To investigate the role of contextual knowledge in reading efficiency across different age groups.
  • To examine how working memory (WM) capacity and attentional demands modulate the effect of contextual knowledge.
  • To identify the primary predictors of reading efficiency.

Main Methods:

  • Participants of varying ages (young, middle-aged, older adults) read ambiguous texts with or without contextual titles.
  • Participants were stratified by high/low working memory (WM) span.

  • An auditory target detection task manipulated attentional demands concurrently with reading.

    • Main Results:

    • Contextual knowledge significantly enhanced reading efficiency, particularly for low WM span individuals.
    • The benefits of contextual knowledge were amplified by increased age and concurrent attentional demands.
    • Contextual knowledge emerged as the strongest predictor of reading efficiency, surpassing other factors like interest and effort.

    Conclusions:

    • Contextual knowledge effectively reduces cognitive load, thereby improving reading efficiency.
    • Age and attentional load interact with contextual knowledge to influence reading performance.
    • Strategic use of contextual information is crucial for optimizing reading comprehension across diverse populations.
