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.

本研究使用点探测任务（DPT）的改良眼动追踪版本，考察在愤怒、快乐和中性面孔出现时的注意偏向。研究对象为111名9至48个月大的幼儿。儿童被动观看一个情感注意偏向任务，该任务包括一个面孔配对（中性面孔与中性、愤怒或快乐面孔配对），持续500毫秒，随后在屏幕一侧出现一个持续1500毫秒的星号探测刺激。一致性试验是指探测刺激出现在与情感面孔同侧的试验，不一致性试验是指探测刺激出现在情感面孔异侧的试验。测量了两种试验类型中注视探测刺激的潜伏期，而非传统任务中的按键潜伏期，并通过用不一致性试验中探测刺激的潜伏期减去一致性试验中探测刺激的潜伏期来计算偏向分数。本研究结果表明，DPT的这个改良版本具有良好的内部信度，且在生命的前4年中存在对愤怒和快乐面孔的偏向。将DPT改良版本成功用于眼动追踪，为早期注意行为研究提供了一种有前景的方法工具，并为焦虑症已确定风险因素的全面纵向研究提供了一种工具。（PsycINFO数据库记录）
