本研究采用改进的眼动仪点探测任务（DPT）考察了愤怒、高兴和中性面孔下的注意偏向。参与者是111名9至48个月的幼儿。儿童被动地观看情感注意力偏差任务，该任务包括面部配对（中性与中性、愤怒或快乐配对）500 ms，然后在屏幕的一侧使用1,500 ms的星号探针。一致性试验是指探针出现在屏幕上与情绪化面孔同一侧的试验，而不一致性试验是指探针出现在情绪化面孔的另一侧的试验。注视探针的潜伏期，而不是传统任务的按钮按压潜伏期，测量两种类型的试验和偏差分数计算减去潜伏期的探针上一致的试验从不一致的试验。目前的研究结果表明，积极的内部可靠性，这种修改版本的DPT以及存在的偏见，在第一个4年的生活中，愤怒和快乐的面孔。成功地使用修改后的版本的DPT上使用的眼动仪提出了一个有前途的方法学工具，研究早期注意行为，并提供了一个工具，全面的纵向研究确定的风险因素焦虑。
This study examines attentional biases in the presence of angry, happy and neutral faces using a modified eye tracking version of the dot probe task (DPT). Participants were 111 young children between 9 and 48 months. Children passively viewed an affective attention bias task that consisted of a face pairing (neutral paired with either neutral, angry or happy) for 500 ms that was followed by a 1,500-ms asterisk probe on 1 side of the screen. Congruent trials were trials in which the probe appeared on the same side of the screen as the emotional face and incongruent trials were trials in which the probe appeared on the opposite side of the emotional face. The latency to fixate on the probe, rather than the traditional task's button press latency, was measured for both types of trials and a bias score was calculated by subtracting the latency to the probe on congruent trials from that on incongruent trials. The results of the current study indicate positive internal reliability of this modified version of the DPT as well as the presence of a bias toward both angry and happy faces during the first 4 years of life. The successful use of the modified version of the DPT for use on the eye tracker presents a promising methodological tool for research on early attentional behavior and provides a tool for comprehensive longitudinal studies of identified risk factors for anxiety.
