Summary

This study investigates how conscious and unconscious visual information interact to guide attentional allocation. While previous research established that unconscious cues can bias attention, it remained unclear how these implicit signals compete with or complement strong conscious stimuli. The authors aimed to determine whether overt attentional exploration is influenced by unconscious cues and how the reliability of conscious information modulates this influence. They hypothesized that eye movements would be guided by unconscious cues, but that strong, reliable conscious signals would suppress this preferential gaze allocation. The experiment involved 20 participants performing a motion discrimination task where they reported the direction of motion for two colored dot patches. Unbeknownst to participants, specific colors were consistently associated with specific motion directions (100% valid association), creating an unconscious cue. Motion coherence was manipulated to vary signal strength: "easy" trials had high coherence (60%), while "difficult" trials had low coherence (25%). Eye movements were tracked to measure attentional allocation. Participants completed a post-experiment questionnaire to verify that learning remained unconscious; those who explicitly reported the color-motion association were excluded. Statistical analyses utilized Bayesian ANOVA to assess accuracy, reaction times, and gaze patterns. The results confirmed that participants implicitly learned the color-motion association, as evidenced by improved accuracy and faster reaction times for predictive colors, despite failing to report the association consciously. Crucially, eye-tracking data revealed that participants preferentially fixated on patches with predictive colors only when motion coherence was low (difficult trials). In trials with high coherence (easy trials), there was no significant difference in gaze allocation between predictive and non-predictive patches. This interaction indicates that unconscious cues guide attention primarily when conscious information is weak or ambiguous. When conscious cues were strong, they suppressed the influence of unconscious information on gaze allocation. These findings demonstrate that conscious and unconscious sources of information interact dynamically to influence visual attention. The study suggests a selection process where cues are weighted in proportion to their reliability. Unconscious learning biases attentional allocation, but this bias is suppressed when strong, task-relevant conscious information is available. This implies that the visual system prioritizes reliable conscious signals over implicit statistical regularities, optimizing resource allocation based on the expected information gain from available cues.
