Toward conjoint analysis of simultaneous eye-tracking and fMRI data for program-comprehension studies

After decades of research, there is still no comprehensive, validated model of program comprehension. Recently, researchers have been applying psycho-physiological measures to expand our understanding of program comprehension. In this position paper, we argue that measuring program comprehension simultaneously with functional magnetic resonance imaging (fMRI) and eye tracking is promising. However, due to the different nature of both measures in terms of response delay and temporal resolution, we need to develop suitable tools. We describe the challenges of conjoint analysis of fMRI and eye-tracking data, and we also outline possible solution strategies.
