“…The results of physiological responses showed statistically significant increases in SCL, SCR, NSCR, HR, RESP and activation in the CORs except RRI. This supports previous results (Main, Shelton-Rayner, Harkin and Williams, 2003;Lundgren, Berggren and Carlsson, 2004), reflecting activation of sympathetic responses indicating fearspecific responses, e.g., increased HR and respiration, sweat secretion, and visceral arousal (James, 1884).…”

The purpose of this study is to examine the physiological responses to predict the psychological level of perceived fear. Thirty male and female college students (15 male and 15 female, mean age: 22.6±1.24) participated in the experiment. EDA (electrodermal activity), ECG (electrocardiogram), and facial EMG (electromyogram) as physiological signals were measured on the subjects' hands and face for 60sec before presentation of emotional stimulus and for 120sec during presentation of stimulus. Experimental conditions consisted of emotional condition where fear was induced by a threatening film clip and neutral condition where no emotion was provoked by a neutral film clip. After presentation of the stimulus, subjects rated their experienced emotion on the emotion assessment scale. Analysis of psychological responses was performed to examine appropriateness (label of the subjects' experienced emotion) and effectiveness (intensity of their experienced emotion). In the analysis of physiological responses, the selected features were skin conductance level (SCL), skin conductance response (SCR), number of skin conductance response (NSCR), R-R interval (R-R), heart rate (HR), respiration (RESP), activation in the bilateral corrugators (COR), and bilateral orbicularis oris' (ORB). The results showed that the psychological responses to stimulus were appropriate and effective. Physiological responses showed significant increases in all features except R-R and ORB during fear condition compared to baseline condition. Also, the perceived level of fear was positively correlated with SCL, SCR, and ORB. Our result offer that the users' perceived emotion i.e., individual differences of psychological responses must be considered to recognize human emotions by physiological signals in HCI.

“…These informants may have acquired their dental fear by hearing stories from relatives or friends and were sure that drilling was an unpleasant and painful method in spite of the fact that they had never experienced the method previously. This is in line with studies showing that dental fear can come either through direct exposure to a negative experience, associated with dental treatment, or indirectly through exposure to information from others who have had negative dental experiences .…”

“…In recent years, numerous investigations on the psychophysiology of dentophobia, using confrontation with disorder‐specific pictures, videos, as well as sounds, have been published . The majority of these investigations reported that dentophobic subjects display heart‐rate acceleration when presented with dental treatment scenes, reflecting defensive fear mobilization .…”

“…There are no published investigations on activation of this muscle region during symptom elicitation in dentophobia. The only published study on dentophobia employing the facial electromyogram (EMG) showed heightened levels of forehead muscle tension during presentation of film clips showing dental drilling or injections compared with neutral scenes . However, the study did not employ a non‐fearful control group.…”

Men and women with dentophobia differ in specific fear contents and underlying brain activity during symptom provocation. Possible sex differences concerning other basic emotions, such as disgust, have undergone minimal investigation. Therefore, we recorded the facial electromyogram from the musculus levator labii (as a specific disgust indicator) and the heart rate of 36 individuals with dentophobia (18 women and 18 men with comparable disorder severity) and of 36 non-phobic controls (18 women and 18 men). The participants were asked to look at pictures showing dental treatment scenes, generally fear- and disgust-inducing, as well as pictures with neutral contents. Subsequently they performed an affective picture rating. Independently of sex, phobic subjects relative to controls showed heart-rate acceleration when watching pictures of dental treatment scenes, reflecting a fear reaction. Male and female phobic subjects did not differ in their verbal reports of fear and disgust experienced. However, phobic women showed enhanced disgust-related facial electromyographic activity to dental treatment scenes relative to men. This sex-specific response pattern points to the greater relevance of disgust for the female symptomatology of dentophobia, or it might also be possible that male patients more successfully inhibit disgust reactions during confrontation.
