Does fear conditioning via mental imagery influence subsequent attention?

Area of Science:

• Cognitive Psychology
• Neuroscience
• Psychophysiology

Background:

• Mental imagery involves creating internal visual representations without external stimuli.
• Fear conditioning with imagined stimuli can generalize to real-world perceptions.
• The impact of imagined fear on subsequent attentional processes remains largely unexplored.

Purpose of the Study:

• To investigate if fear conditioning acquired through mental imagery affects subsequent attention.
• To explore the role of individual differences in mental imagery vividness in this process.

Main Methods:

• Participants underwent a fear conditioning task using imagined conditioned stimuli (CS+) paired with shock and neutral stimuli (CS-).
• A visual search task was used to assess attentional bias towards colors associated with the imagined CS+ and CS-.
• Skin conductance response and self-reported fear were measured.

Main Results:

• No significant group-level attentional bias towards the imagined CS+ was observed in Experiment 1.
• Experiment 2 revealed an unexpected attentional bias towards the imagined CS- color, potentially acting as a safety signal.
• Attentional bias towards the imagined CS+ was positively correlated with participants' vividness of mental imagery.

Conclusions:

• The influence of fear conditioning via mental imagery on attention is dependent on an individual's capacity for vivid mental imagery.
• These findings highlight the significant role of internal representations in modulating attentional responses and fear generalization.
