Stimuli associated with cocaine use capture attention. Evidence suggests that fixation time measured on the visual probe task is a valid measure of cocaine cue attentional bias. The aim of this experiment was to demonstrate the test-retest reliability of cocaine cue attentional bias as measured by fixation time during the visual probe task.
In a within-subject, repeated-measures design, thirty-six non-treatment seeking cocaine-using adults completed a visual probe task with eye tracking.
Participants displayed an attentional bias to cocaine-related images as measured by fixation time across two occasions (F (1, 35) = 56.5, p < 0.0001). A Pearson correlation indicated significant test-retest reliability for this effect (r = 0.51, p = 0.001). Response time failed to detect an attentional bias and test-retest reliability was low (r = 0.24, p = 0.16).
Fixation time during the visual probe task is a reliable measure of cocaine cue attentional bias in cocaine-using adults across time.
与使用可卡因相关的刺激会吸引注意力。有证据表明，在视觉探测任务中测量的注视时间是可卡因线索注意偏向的有效指标。本实验的目的是证明在视觉探测任务中通过注视时间测量的可卡因线索注意偏向的重测信度。
在一项被试内重复测量设计中，36名未寻求治疗的可卡因使用成年个体完成了一项带有眼动追踪的视觉探测任务。
通过两次测量的注视时间来衡量，参与者对与可卡因相关的图像表现出注意偏向（F(1, 35) = 56.5，p < 0.0001）。皮尔逊相关分析表明这种效应具有显著的重测信度（r = 0.51，p = 0.001）。反应时间未能检测到注意偏向，且重测信度较低（r = 0.24，p = 0.16）。
在视觉探测任务中的注视时间是可卡因使用成年个体随时间推移对可卡因线索注意偏向的可靠测量指标。
