High perceptual load makes everybody equal: eliminating individual differences in distractibility with load

Area of Science:

• Cognitive psychology
• Attention research

Background:

• Perceptual load is a key factor influencing distractibility in controlled settings.
• Individual differences in daily distractibility are well-documented.

Purpose of the Study:

• To investigate the relationship between laboratory-assessed perceptual load and real-world distractibility.
• To determine if high perceptual load can mitigate individual differences in distractibility.

Main Methods:

• Sixty-one participants completed a response-competition task with varying perceptual load.
• Individual distractibility was measured using the Cognitive Failures Questionnaire.

Main Results:

• Individuals reporting higher daily distractibility experienced more interference under low perceptual load.
• High perceptual load significantly reduced distractor interference for all participants, eliminating individual differences.

Conclusions:

• Perceptual load level predicts the emergence of individual differences in distractibility.
• Increasing perceptual load in everyday tasks may be a strategy to manage distractibility.
