Prior work has examined neural correlates of face valence judgments at threshold.

The present study investigated what brain systems are important for resolving emotional ambiguity of a repeatedly presented emotionally ambiguous stimulus. Thirty participants (Female=21, Mage=21.71) completed an emotional face judgment task on repeated exposure to an emotionally ambiguous face that could be judged as sad or neutral. The image was individually chosen for each subject prior to the experiment using a threshold detection procedure on eleven different levels of sad-to-neutral morphing. General linear models were constructed to assess how task-evoked responses differed between the two percepts. Group-level results did not reveal any significant differences between the two conditions. The absence of task-evoked differences at the group-level could reflect different decision-making strategies that e.g., give weight to different types of stimuli features across individuals. Alternatively, repeating these analyses in a larger sample will clarify whether a larger effect size is needed given subtle differences between perceptual outcomes.
