Attention Bias Modification (ABM) is used to manipulate attention biases in anxiety disorders. It has been successful in reducing attention biases and anxious symptoms in social anxiety and generalized anxiety, but not yet in specific fears and phobias.
We designed a new version of the dot-probe training task, aiming to train fearful participants' attention away from or towards pictures of threatening stimuli. Moreover, we studied whether the training also affected participants' avoidance behavior and their physical arousal upon being confronted with a real threat object.
In Experiment 1, students with fear of spiders were trained. We found that the attention manipulation was successful, but the training failed to affect behavior or arousal. In Experiment 2, the same procedure was used on snake-fearful students. Again, attention was trained in the expected directions. Moreover, participants whose attention had been trained away from snakes showed lower physiological arousal upon being confronted with a real snake.
The study involved healthy students with normal distribution of the fear of spider/snake. Future research with clinical sample could help with determining the generalizability of the current findings.
The effect of ABM on specific phobia is still in question. The finding in the present study suggested the possibility to alter attentional bias with a dot-probe task with general positive stimuli and this training could even affect the behavior while encountering a real threat.
注意偏向矫正(ABM)用于操控焦虑症中的注意偏向。它已成功减少社交焦虑和广泛性焦虑中的注意偏向及焦虑症状,但在特定恐惧和恐惧症方面尚未成功。
我们设计了一个新版的点探测训练任务,旨在训练恐惧的参与者将注意力从威胁性刺激图片上转移开或转向此类图片。此外,我们研究了该训练是否还会影响参与者在面对真实威胁物体时的回避行为及其身体唤醒水平。
在实验1中,对害怕蜘蛛的学生进行了训练。我们发现注意操控是成功的,但训练未能影响行为或唤醒水平。在实验2中,对害怕蛇的学生采用了相同程序。同样,注意力被训练到预期方向。此外,那些注意力被训练得远离蛇的参与者在面对真实蛇时表现出较低的生理唤醒水平。
该研究涉及对蜘蛛/蛇恐惧呈正态分布的健康学生。未来对临床样本的研究可能有助于确定当前研究结果的普遍性。
ABM对特定恐惧症的效果仍存在疑问。本研究中的发现表明,使用带有一般积极刺激的点探测任务改变注意偏向是有可能的,并且这种训练甚至可能在遇到真实威胁时影响行为。
