Reduction of interference effect by low spatial frequency information priming in an emotional Stroop task

Area of Science:

• Cognitive Psychology
• Neuroscience
• Visual Perception

Background:

• The affective prediction hypothesis posits that visual expectation enhances emotional stimulus processing.
• Prediction involves identifying likely objects and inhibiting unlikely ones.
• Emotional perception facilitation is linked to low spatial frequency (LSF) extraction, but its role in prediction with irrelevant stimuli is unexplored.

Purpose of the Study:

• To investigate the role of visual expectation and LSF information in emotion recognition amidst irrelevant stimuli.
• To examine how prediction, influenced by LSF, affects the inhibition of irrelevant information.

Main Methods:

• A novel emotional Stroop task was developed.
• Participants identified emotional facial expressions (EFEs) presented with congruent or incongruent words.
• EFEs were primed with LSF or high spatial frequency (HSF) versions to test prediction efficiency.

Main Results:

• Stroop interference was reduced in the LSF priming condition compared to the HSF condition.
• This indicates that LSF-based visual expectation aids in inhibiting irrelevant information.

Conclusions:

• Visual expectation, particularly relying on early LSF information, facilitates the inhibition of irrelevant information during emotion recognition.
• This supports the affective prediction hypothesis in complex visual scenes.
