Lack of emotional gaze preferences using eye-tracking in remitted bipolar I disorder.

BACKGROUND: Bipolar disorder is associated with heightened and persistent positive emotion (Gruber in Curr Dir Psychol Sci 20:217-221, 2011; Johnson in Clin Psychol Rev 25:241-262, 2005). Yet little is known about information processing biases that may influence these patterns of emotion responding.

METHODS: The current study adopted eye-tracking methodology as a continuous measure of sustained overt attention to monitor gaze preferences during passive viewing of positive, negative, and neutral standardized photo stimuli among remitted bipolar adults and healthy controls. Percentage fixation durations were recorded for predetermined areas of interest across the entire image presentation, and exploratory analyses were conducted to examine early versus late temporal phases of image processing.

RESULTS: Results suggest that the bipolar and healthy control groups did not differ in patterns of attention bias.

CONCLUSIONS: Findings provide insight into apparently intact attention processing despite disrupted emotional responding in bipolar disorder.
