Discovery of Event-Related Potentials during a Cognitive Process of Comparison Operation

Cognitive processes and mental states of software developers have been investigated using electroencephalogram (EEG) in software engineering. However, the feasibility of eventrelated potential (ERP) analyses for program comprehension were rarely examined. In this study, we aimed to discover the ERPs related to program comprehension. We conducted an experiment to capture ERPs with ten software developers during a cognitive process of comparison operation as one of the simple program comprehension processes. As results, ERP waveforms were observed in the EEG data of four subjects. In addition, we confirmed the inter-stimulus difference in peak amplitudes and peak latency.
