Action priming is linked to visual perception in continuous flash suppression

Area of Science:

• Cognitive Neuroscience
• Visual Perception
• Psychology

Background:

• Visual prime stimuli can influence subsequent target processing, even when masked.
• Continuous Flash Suppression (CFS) is a technique to reduce stimulus visibility.
• The impact of CFS on action priming is not well understood.

Purpose of the Study:

• To investigate how Continuous Flash Suppression (CFS) affects action priming.
• To compare the effects of CFS on prime visibility and action priming.
• To explore the relationship between individual differences in perception and action priming under CFS.

Main Methods:

• Modulated prime visibility using CFS by varying prime contrast, mask contrast, and stimulus onset asynchrony.
• Measured action priming effects of masked stimuli under different CFS conditions.
• Examined correlations between individual differences in prime visibility and action priming.

Main Results:

• Action priming effects were modulated in parallel with prime visibility by CFS parameters.
• Individual differences in prime visibility correlated with action priming.
• CFS demonstrated parallel effects on perception and action, unlike backward masking.

Conclusions:

• CFS interferes with early visual processing, impacting both perception and action similarly.
• Findings suggest CFS affects visual processing stages common to both perception and action.
• CFS provides a unique tool for studying the relationship between perception and action.
