Sluggish cognitive tempo (SCT) is a kind of attentional symptoms characterized by symptoms of slowness in behavior or in thinking. The aim of the present study was to develop a preliminary attention training program based on real-time eye-gaze feedback using an eye-tracker. A total of 38 participants with SCT were randomly assigned to one of following two conditions: eye-feedback ( = 19; Mean Age = 21.21; range 18-26) or control ( = 19; Mean Age = 20.68; range 18-25). The participants in the eye-feedback condition received three repeated trainings on the modified version of the Posner's spatial cueing test; we also used real-time constant eye-gaze feedback designed to lead the participants to quickly and accurately engage and to disengage, with pre- and post- measurement of eye-movements (overt attention) and the revised attention network test (ANT-R; covert attention). The participants in the control condition received three repeated same trainings without any feedback, with pre- and post-measurement of eye-movements measure and ANT-R. The results revealed that the eye-feedback group showed a greater improvement in engaging and disengaging attention through the overt attention measure than the control group. The eye-feedback group also showed a greater increase only in the orienting network related to disengaging attention in the covert attention measure compared to the control group. These results suggested that the eye-feedback can be meaningfully used in attention training to enhance the efficiency of attention in clinical settings.
迟缓认知节奏(SCT)是一种以行为或思维迟缓症状为特征的注意力症状。本研究的目的是使用眼动仪开发一种基于实时眼动注视反馈的初步注意力训练方案。共有38名患有SCT的参与者被随机分配到以下两种情况之一:眼动反馈组(n = 19;平均年龄 = 21.21岁;范围18 - 26岁)或对照组(n = 19;平均年龄 = 20.68岁;范围18 - 25岁)。眼动反馈组的参与者在修改版的波斯纳空间线索测试中接受了三次重复训练;我们还使用了实时恒定眼动注视反馈,旨在引导参与者快速准确地参与和脱离,并对眼动(外显注意力)和修订后的注意力网络测试(ANT - R;内隐注意力)进行前后测量。对照组的参与者接受了三次重复的相同训练,但没有任何反馈,并对眼动测量和ANT - R进行前后测量。结果显示,与对照组相比,眼动反馈组在外显注意力测量中表现出在参与和脱离注意力方面有更大的改善。与对照组相比,眼动反馈组在内隐注意力测量中仅在与脱离注意力相关的定向网络中也表现出更大的增加。这些结果表明,眼动反馈可以有效地用于注意力训练,以提高临床环境中注意力的效率。
