Key result
Physiological signals during video-based learning, specifically the variance of Galvanic Skin Response, showed a significant moderate positive correlation (r=0.50) with the personality trait of Extraversion.
Why the study?
Existing marker systems for assessing personality traits have limitations such as unavoidable dishonest responses, prompting the development of an assessment method relying on physiological signals.

Physiological signals such as heart rate and galvanic skin response variance correlate with students' personality traits during video-based learning.
Hypothesis-generating for personality-tailored video learning; prospective studies needed before educational applications.
Past researches show that personality trait is a strong predictor for one’s academic performance. Today, mature and verified marker systems for assessing personality traits already exist. However, marker systems-based assessing methods have their own limitations. For example, dishonest responses cannot be avoided. In this research, the goal is to develop a method that can overcome the limitations. The proposed method will rely on physiological signals for the assessment. Thirty participants have participated in this experiment. Based on the statistical results, we found that there are correlations between students’ personality traits and their physiological signal change when learning via videos. Specifically, we found that participants’ degree of extraversion, agreeableness, conscientiousness, and openness to experiences are correlated with the variance of heart rates, the variance of GSR values, and the skewness of voice frequencies, etc.

Tseng et al. (2022) conducted a cross-sectional in Healthy students (n=30). Video-based learning was evaluated on Correlation between Extraversion and variance of Galvanic Skin Response (GSR) (r = 0.5034, p=<0.01). Physiological signals during video-based learning, specifically the variance of Galvanic Skin Response, showed a significant moderate positive correlation (r=0.50) with the personality trait of Extraversion.
