研究人员一直在使用心理生理学的方法来更好地理解程序理解,例如同时使用fMRI和眼动追踪来验证自上而下的理解模型。在本文中,我们认为除了眼睛注视之外,眼睛跟踪数据还有额外的价值:瞳孔扩张和眨眼率可以提供对程序员认知负荷的见解。然而,fMRI环境可能会影响瞳孔扩张和眨眼率,这将降低其信息价值。我们对22名学生参与的fMRI实验的瞳孔扩张和眨眼率进行了初步分析。我们的初步分析得出结论,我们的功能磁共振成像环境的校正是具有挑战性的,但可能的,这样我们就可以使用瞳孔扩张和眨眼率更可靠地观察程序的理解。
Researchers have been employing psycho-physiological measures to better understand program comprehension, for example simultaneous fMRI and eye tracking to validate top-down comprehension models. In this paper, we argue that there is additional value in eye-tracking data beyond eye gaze: Pupil dilation and blink rates may offer insights into programmers' cognitive load. However, the fMRI environment may influence pupil dilation and blink rates, which would diminish their informative value. We conducted a preliminary analysis of pupil dilation and blink rates of an fMRI experiment with 22 student participants. We conclude from our preliminary analysis that the correction for our fMRI environment is challenging, but possible, such that we can use pupil dilation and blink rates to more reliably observe program comprehension.
