Value-driven attentional and oculomotor capture during goal-directed, unconstrained viewing

Area of Science:

• Cognitive Neuroscience
• Neuroscience
• Psychology

Background:

• Learned stimulus value influences attentional priority.
• Previously rewarded stimuli can involuntarily capture covert attention.
• It remains unclear if reward history drives involuntary eye movements.

Purpose of the Study:

• To investigate if previously rewarded stimuli capture both attention and eye movements involuntarily.
• To explore the relationship between value-driven oculomotor capture and visual working memory capacity.
• To provide physiological evidence for reward-predictive cueing in value-driven capture.

Main Methods:

• Observing behavior during unconstrained viewing tasks.
• Measuring eye movements and fixations.
• Assessing individual differences in visual working memory capacity.
• Monitoring pupil dilation as a physiological indicator.

Main Results:

• Previously rewarded, task-irrelevant stimuli involuntarily captured attention and eye movements (oculomotor capture).
• Value-driven oculomotor capture correlated with visual working memory capacity.
• Pupil dilation increased in response to reward-associated stimuli post-training.

Conclusions:

• Reward history creates a strong link between attention and eye movements.
• Value-driven capture demonstrates that stimuli can become involuntary reward-predictive cues.
• Findings have significant implications for attention and reward learning theories.
