Working memory load impacts information processing. As memory load increases, later presented stimuli elicit smaller P300 amplitudes, indicating reduced processing resources for event-related potentials.

Area of Science:

  • Cognitive Neuroscience
  • Psychology

Background:

  • Working memory is crucial for temporarily storing and manipulating information.
  • Event-related potentials (ERPs), such as P300, reflect cognitive processing.
  • Understanding resource allocation in working memory is key to cognitive function.

Purpose of the Study:

  • To investigate how information processing in working memory is affected by sequential stimulus presentation.
  • To examine the relationship between working memory load, P300 amplitude, and recall accuracy.
  • To explore the allocation of processing resources during memory tasks.

Main Methods:

  • Subjects memorized sequences of visually presented consonants in a working memory task.
  • Event-related potentials (ERPs) were recorded and averaged for each stimulus position.

  • A control task with a reduced working memory load was used for comparison.

    • Main Results:

    • P300 amplitude decreased for stimuli presented later in the sequence during the high working memory load task.
    • Recall errors increased for later presented stimuli.
    • P300 amplitude was independent of presentation position in the low load control task.

    Conclusions:

    • Increasing working memory load consumes processing resources, diminishing the ability to process later incoming stimuli.
    • P300 amplitude serves as an indicator of available processing resources.
    • This suggests a trade-off between memory encoding and stimulus processing under high cognitive load.
