Area of Science:

  • Cognitive psychology
  • Neuroscience
  • Psychophysiology

Background:

  • Attentional tasks are crucial for understanding cognitive processing.
  • Measuring processing capacity is vital in various psychological and neurological contexts.
  • Factors like stress and fatigue significantly impact cognitive performance.

Purpose of the Study:

  • To introduce a novel, demanding attentional task.
  • To assess the task's sensitivity to factors reducing processing capacity.
  • To highlight the task's brevity and ease of administration.

Main Methods:

  • The task involves rapid alternation between color naming and number transformation.
  • It requires high demands on cognitive processing capacity.
  • The task's sensitivity to performance-reducing factors was evaluated.
