Internet is fast developed and widely used in the world. People use internet for variety purposes, and over one billion users played computer games, but some of them addicted to internet or online game which was called Internet Gaming Disorder (IGD). IGD was defined and suggested investigating through standard criteria proposed by DSM-5. The symptoms of IGD include preoccupation with online activity, withdrawal, tolerance, and escape or relief from a negative mood. Some studies and scales considered that emotion was one feature or assessment of internet addiction (IA). Emotion brings psychological and physiological information of IGD. This study aimed to investigate emotional responses of IGD. Fifty college subjects in Taiwan were recruited and participated in an emotional induced experiment. IGD gamers reported different emotional intensity and expressed different autonomic nervous activity (from HRV) than non-IGD gamers when watching online game films. The emotional feature of IGD is worthy to be further studied to assist the development of research and applications.

Internet gaming disorder (IGD) was regarded as behavioral addiction, and the common characteristics of internet addiction (IA) or IGD were craving, tolerance, withdrawal, mood modification, and salience. The fifth version of Diagnostic and Statistical Manual of Mental Disorders, addressed IGD, and also proposed 9 research criteria for IGD in 2013. Emotion was reported one character of IGD, and this study hypothesized that emotion was both a response and an influential factor on IGD. The self-report for emotion and questionnaires (psychological character), and electrocardiography (ECG) (physiological signal) of participants in emotional state were collected and analyzed in a non-invasive manner. An emotional induction experiment using online game film clips was conducted. Nineteen participants were grouped into IGD& high-risk internet addiction group, and 21 were in non-IGD & low-risk internet addiction group. The physiological signal (ECG) was used to study emotional responses of IGD. The sympathetic and parasympathetic activities were obtained from heart rate variability (HRV). The IGD addicts exhibited more positive emotion, and stronger sympathetic activity, but felt weaker physiological activity for online game than non-IGD addicts. Emotion can provide a short-term, quick response and dynamic changes of psychological and physiological information of IGD addicts, and that allowed researcher to develop further application, such as monitoring system, early alarm system, early IGD detection, and even prevention.

Background: Internet addiction can be generally conceptualized as excessive computer and Internet use which results in negative consequences in physical or mental functions. In recent years, Internet addiction is a growing problem around the world, and should be studied through scientific methods. Some studies indicated that Internet addiction was correlated to physical responses including heart rate, respiration, and psychological reactions including emotion, social interaction. This study assumed that emotion was one of significant roles in Internet addiction, and emotion can be observed by subjective self-report and objective autonomic nervous responses. Respiration can be a type of biofeedback to regulate respiratory rate and amplitude which affects autonomic nervous responses. The respiratory features in emotion states of Internet addiction abusers were investigated by Complementary Ensemble Empirical Mode Decomposition. Results: The results showed that the respiratory features of Internet addiction abusers differed from normal Internet users among different emotions. Such results could be expected to monitor or assist to treat Internet addiction.

Background and aims: People with internet addiction (IA) suffer from mental, physical, social, and occupational problems. IA includes psychological and physiological syndromes, and among the syndromes, emotion was suggested important mental and physiological expressions of IA. However, few physiologically emotional characters of IA were investigated. Autonomic nervous system (ANS) activity was a good link between IA and emotion, and respiratory sinus arrhythmia (RSA) gained from ANS was hypothesized related to IA. Methods: An emotional induction experiment using negative and positive emotional films was conducted to validate the hypotheses. Thirty-four participants recruited from college were classified into high-risk IA group (HIA) and low-risk IA group (LIA). The respiratory signals, ECG signals, and self-assessed emotional intensity were acquired. The relationship and difference between IA and RSA was tested using descriptive statistics and inferential statistics. Results: The RSA values of HIA were lower than those of LIA both before and after the induction of positive and negative emotions. When participants experienced a negative emotion (anger or fear), their RSA values declined; the decline for HIA was greater than that for LIA. The RSA values of HIA participants before induction of fear, happiness, or surprise, statistically significantly differed from that after induction of those emotions, with p values of 0.007, 0.04 and 0.01 respectively. The difference between the changes in RSA values upon the induction of surprise of HIA and LIA was statistically significant difference (p = 0.03). The interaction between two IA groups among emotional induction states was statistically significant difference. Conclusions: RSA value here was the main variable that reflected ANS activity, and especially vagus nerve regulation. The results revealed that the changes in RSA values were biologically significantly different between HIA and LIA, especially when sadness, happiness, or surprise was induced. HIA people exhibited stronger RSA reactivity following negative emotion than LIA people, but the RSA reactivity following positive emotion was weaker. This study provides more physiological information about IA and assists further investigation on the regulation of the ANS for IA abusers. The results will benefit the further application, early detection, therapy, and even early prevention.
