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.
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 suggest that the bipolar and healthy control groups did not differ in patterns of attention bias.
Findings provide insight into apparently intact attention processing despite disrupted emotional responding in bipolar disorder.
双相情感障碍与强烈且持续的积极情绪有关（格鲁伯，《当代心理学科学发展方向》，2011年，第20卷，第217 - 221页；约翰逊，《临床心理学评论》，2005年，第25卷，第241 - 262页）。然而，对于可能影响这些情绪反应模式的信息加工偏差，我们知之甚少。
本研究采用眼动追踪方法，作为对持续明显注意力的连续测量，以监测缓解期双相情感障碍成年患者和健康对照在被动观看正性、负性和中性标准化照片刺激时的注视偏好。在整个图像呈现过程中，记录预定感兴趣区域的注视持续时间百分比，并进行探索性分析，以检查图像处理的早期和晚期阶段。
结果表明，双相情感障碍组和健康对照组在注意力偏差模式上没有差异。
研究结果为双相情感障碍患者尽管情绪反应紊乱但注意力加工明显完好提供了见解。
