  • Objectives : The neural substrate of fear is thought to be highly conserved among species including human. The purpose of this review was to address the neural substrates of fear based on recent findings obtained from animal and human studies. Methods : Recent studies on brain regions related to fear, particularly fear conditioning in rodents and humans, were extensively reviewed. Results : This paper suggests high consistency in anatomical structure and physiological mechanisms for fear perception, response, learning and modulation in animals and humans. Conclusions : Fear is manifested and modulated by well conserved neural circuits among species interconnected with the amygdala, such as the hippocampus and the ventromedial prefrontal cortex. Further research is required to incorporate findings from animal studies into a better understanding of neural circuitry of fear in human in a translational approach.

  • Objective : Although studies have explored responses to fear had been assessed using various psychophysiological methods, results have been inconsistent. The present study examined psychophysiological responses in healthy subjects after viewing fear stimuli in a video clip for set up future fear related psychophysiological studies. Methods : We monitored three psychophysiological variables (electroencephalography, skin temperature, and heart rate variability) in adults who watched either a control stimulus movie clip or a fear-inducing movie clip. Results : In 16 healthy adults, theta activity decreased significantly after the fear stimulus as compared to the normal stimulus. However the participants showed no differences in heart rate variability or skin temperature between the fear and normal control stimulus situations. Conclusion : In the limbic area, theta activity corresponds with information processing, integration into previous memories and long-term potentiation. In this study, we suggest decreased theta activity represents amygdalo-hippocampal activity, associated with fear, short-term memory, and memory extinction in the healthy adults. Further studies are needed to evaluate the interaction of fear, memory, and the pathophysiology of anxiety disorder in patient with anxiety disorders.

  • This study aimed to explore the themes and parameters of environmental health behaviors based on Rogers' protection motivation theory through a systematic mapping review. Using a systematic approach, a literature review was conducted of articles that adopted Rogers' protection motivation theory. A total of 11 articles on protection motivation theory using participants and environmental health as outcomes were identified in a search of CINAHL, Cochrane Library, EMBASE, Eric, PsycARTICLES, PubMed, and RISS between September 1 and September 8, 2021. Themes related to the environment and personal behaviors between 2002 and 2021 were extracted. The parameters based on protection motivation theory were identified through systematic mapping as fear appraisal, rewards of maladaptive response, severity, vulnerability, costs of adaptive response, response efficacy, self-efficacy, and intention. Self-efficacy and response efficacy considerably affected environmental health behaviors. Emotional fear appeal related to environmental hazards motivates an internal process that alters the threat appraisal and their coping appraisal. Environmental behavior perception and intention influenced on environmental health behaviors with small effect sizes. Therefore, a deeper understanding of the severity of environmental health issues could lead to the development of helpful, effective, and intensive interventions to promote healthcare among the vulnerable population.

  • This study analyzed the mediator effect of fear and helping responses on relationship between familiarity and discrimination based on the contact theory. We presented typical vignettes of schizophrenia, depression and alcoholism to 922 adults randomly. All respondents were asked for direct and indirect contact experiences with mental illness, fear and helping responses and discrimination against persons with mental illness. Our findings suggest that contact theory was not supported in every types of mental disorders. In schizophrenia, fear and help were the full mediator between familiarity and discrimination. In depression, only helping response was the mediator between familiarity and discrimination. But in alcoholism, familiarity did not predict discrimination. Based on theses findings, we suggest various anti-stigma strategies depending on the types of mental disorders.

  • The purpose of this study is to examine the effect of sympathetic reactions to public service advertisement video messages produced for health campaigns. To this end, based on the empathy response scale proposed by Campbell & Babrow (2004), the empathy response to the images of nine health campaigns with themes of smoking cessation, tuberculosis, and suicide triggered fear of health risks and health behaviors (information seeking, preventive actions). As a result of the analysis, among the factors of empathy reaction, the reality of the message creative, the match of emotions, and the identification of the characters in the video each played a role in raising fear, and it is rather fear that logically understanding the situation that causes health problems through the health campaign video It was found that it played a role in reducing health information seeking behavior. On the other hand, it was found that the higher the degree of interest, such as sympathy for the characters in the video, among the factors of the sympathetic response to the health campaign, the higher the intention of preventive action to reduce the health risk.

  • The purposes of this study were to assess dental fear and anxiety level of patients attending a dental clinic using the dental fear survey (DFS) scale, to apply interventions chosen by patients for reducing dental fear and anxiety and measure their effects. This study surveyed 34 patients who visited a dental clinic in Seoul about their self-rated health and their experience of dental fear, and measured the level of dental fear using DFS. Trained dental hygienists applied interventions desired by the patients for reducing dental fear and anxiety and, for each intervention, examined the patients' satisfaction (very helpful [5 point]~not helpful at all [1 point]). Collected data were analyzed using IBM SPSS Statistics ver. 21.0 through independent t-test or one-way ANOVA for difference in level of fear according to related characteristics, and through Wilcoxon signed rank test for comparison between before and after the intervention. The subjects' mean level of fear (DFS score) was 44.53, which was an average level, and the level of dental fear was relatively high for stimulus-response (2.72). The level of dental fear was higher in those who had experienced pains or indirect dental fear from dental treatment in the past, and those whose subjectively perceived health state was poor (p<0.05). With regard to the applied dental fear intervention, 'Helpful (3.57)' was the most common answer. Overall satisfaction before and after the application of dental fear intervention was generally high as 4.37 and 4.35, respectively, but it decreased slightly after the intervention. In order to lower the level of dental fear, it is considered effective to survey not only the level of dental fear but also patients' need of dental fear interventions and to apply a suitable intervention. It is also required to educate dental workers and to develop related manuals.
