  • This study examined whether aggression mediates the effects of seven sub-types of narcissistic personality on psychopathy. It hypothesized that some of narcissistic personality could affect aggression that, in turn, contributes to psychopathy. The sample of this study consisted of 864 college students (451 males and 413 females). The participants completed an assessment battery consisting of Narcissistic Personality Inventory(NPI), Aggression Questionnaire(AQ), and Self-Reported Psychopathy Scale(SRPS). According to the results, narcissistic personality and aggression variables affected psychopathy, and aggression predicted students' psychopathy. The effects of students' narcissistic personality on psychopathy were partly mediated by aggression. The research findings partly supported the hypothesis, and were discussed on gender differences in relation among sub-types of narcissistic personality, aggression, and psychopathy. The implications and limitations of this study were suggested.

  • This literature review introduced the concept of psychopathy which has never been defined academically in Korea. Also it is reviewed how this concept could be applied as latent factor of criminal behavior in the forensic settings. For this purpose, first of all, the periodical change of psychopathy definition was explored. Then it was investigated which determinants might develop psychopathy and what would be the behavioral characteristics of psychopaths. Finally, risk assessment tools measuring psychopathy were introduced and their predictive efficacy and applicability in Korean criminal justice system was discussed.

  • The purpose of this study is to conduct an exploratory investigation into Korean psychopathy by synthesizing the results of prior domestic research on the validation of psychopathy assessment tools. Domestic research on the validation of psychopathy scales has been constrained by limited research methodologies, bias toward male subjects, and the application of inappropriate factor structures. Furthermore, although discrepancies between the original scale and the Korean scale were identified regarding the factor structures through in construct validity research, discussion on the concept of Korean psychopathy has been limited. As a result, this study compared 16 domestic papers on the validation of psychopathy assessment tools along with 9 international foreign papers that addressed the factor structure of each original scale. By comparing the derived factor structures, items assigned to each factor, and omitted items from each study, the characteristics of Korean psychopathy were explored. The findings revealed that Korean psychopathy is recognizable from materialism, machiavellianism, and antisocial behavior and impulsivity. This study holds significance in synthesizing the outcomes of current domestic psychopathy validation research and offers a conceptual foundation to help understand Korean psychopathy.

  • This study investigated gender differences in contribution of antisocial personality and affective empathy to psychopathy. Two hundred fifteen college students (male, 118; female,97) completed three measures including the PPI-R(Psychopathic Personality Inventory-Revised), the PAI-ANT(Personality Assessment Inventory-Antisocial Features), and the EETS (Emotional Empathy Tendency Scale). According to the results, the mean scores of PPI-R and EETS in male group were higher than in female group. Antisocial features were positively associated with psychopathy in both male and female groups and negatively with affective empathy. Males showed that the scores of affective empathy were negatively associated with those of antisocial features and psychopath. Females showed that the scores of affective empathy were negatively associated with those of antisocial personality and psychopathy but the correlation was significant only with the scores of antisocial behavior (ANT-A). To scrutinize the differences between male and female groups, the scores on the PAI and EETS were compared between 30% upper and 30% lower groups based on the scores of the PPI-R. According to the results, the upper group of the scores on the PPI had higher scores on the PAI and lower scores on the EETS. The differences of the scores on the EETS between high-psychopathy and low-Psychopathy groups were bigger in male group than in female group. Explanations and implications of the results were discussed and the directions of the future studies were suggested.

  • This study was intended to investigate the contents associated with the neuropsychosis in the medical books published in the times of Chinese dynasty of Jin and Yuan. As a result, the following findings were drawn. 1. As for palpitation from fright and severe palpitation, the medical schools in the times of Chinese Jin and Yuan dynasties viewed their causes as heart-fire, shuiqichengxin, blood vacuity, phlegm and so on and presented a prescription for each cause for them. 2. As for psychosis, medical books published in the times of Chinese Jin and Yuan dynasties accurately divided and discussed epilepsy and viewed their causes largely as Yangming heat, phlegm of chest and heart-fire. And a number of medical schools made use of such therapeutics as sweating, vomiting and diarrhea therapies. 3. As for headache, medical books published in the times of Chinese Jin and Yuan dynasties presented their causes as fire and heat, phlegm heat, phlegm and so on and classified the aspect of headache in detail. As for vacuity rexation and dysphoria, medical books at that time saw their causes as fire and heat, heart-fire, blood vacuity and so forth and presented a prescription for them accordingly. 4. Liu Wan Su was the Hanliang school. He viewed the etiological cause for psychopathy as fire and heat and prescribed largely the medication of cold nature for it. 5. Zhang Cong Zheng belonged to the Gongxia School. He viewed the etiological cause for psychopathy as fire, phlegm and so forth and made use of sweating, vomiting and diarrhea therapies. Especially, he used the 'Jingzhepingzhe' therapy as a method to treat the symptom of fright. 6. Li Gao did not any specific mention of psychopathy and divided headache due to internal injury and headache due to external contraction. 7. Zhu Zhen Heng viewed most of the etiological causes for psychopathy as phlegm, fire and deficiency of blood and attached importance to such its therapeutics as resolving phlegm, cleaning away fire and nourishing Yin. 8. Wang Hao Gu did not present the specifically common etiological cause and prescription for psychopathy but described the cause and prescription for headache, dysphoria, maniac speech, palpitation and so forth. Luo Tian Yi presented the process of psychosis due to abnormal therapy for cold demage and prescription of it. 9. Wang Lu made a detailed explanation about the therapeutics of five types of stagnated syndrome and said that stagnated syndrome became the major cause for them in the occurrence of such psychopathy. Wei Yi Lin presented the prescription and medication for comparatively diverse mental diseases such zhong-qi, severe palpitation, palpitation for fright, impaired memory, vacuity rexation, headache, psychosis.

  • The current study was conducted to explore the relations among college students' narcissistic personality, depression, and psychopathy. This study investigated how narcissistic personality and depression variables relate to psychopathy variables. For this purpose, an assessment battery consisting of Narcissistic Personality Inventory(NPI), Narcissistic Personality Disorder Scale: NPDS), BDI, Self-Reported Psychopathy Scale(SRPS), and Psychopathic Personality Inventory-Revised. PPI-R was administered to 1003 college students (501 males and 502 females). For comparison with the levels of pathological narcissism, the participants were devided two groups( above 33%, below 33% ) based on their scores of the NPDS, According to the results, males had more overt narcissistic personality, and females felt more depressive and psychopathic. The higher level group on the NPDS had higher scores on the NPI, BDI, SRPS and PPI-R. The students' narcissistic personality had relations to depression and psychopathy, but the results were different according to the kind of inventories(PPI-R or SRPS, NPI or NPDS). The implications and limitations of this study, as well as some suggestions for future research, were suggested.

  • Objective: Physical activity restriction in sows may lead to behavioral abnormalities and affective disorders. However, the psychophysiological state of these sows is still unclear. As miRNAs can be used as effective markers of psychopathy, the present study aimed to assess the difference in microRNA expression between the long-term activity restricted sows and activity free sows, thus contributing to the understanding of abnormal sow behavior. Methods: Four dry sows (sixth parity, Large${\times}$White genetic line) were selected from activity restricted crates (RC) or activity free pens (FP) separately. microRNAs in the ventromedial prefrontal cortex (vMPFC) and serum were examined using real-time polymerase chain reaction, and the correlation between the miRNAs expressed in the vMPFC and serum was evaluated. Results: miR-134 (1.11 vs 0.84) and miR-1202 (1.09 vs 0.85) levels were higher in the vMPFC of the RC sows than in the FP sows (p<0.01). Furthermore, miR-132 (1.27 vs 1.08) and miR-335 (1.03 vs 0.84) levels were also higher in the RC sows than in FP sows (p<0.05); however, miR-135a, miR-135b, miR-16, and miR-124 levels were not different (p>0.05). The relative expression of serum miR-1202 was higher in the RC sows than in the FP sows (1.04 vs 0.54) (p<0.05), and there was a strong correlation (R = 0.757, p<0.05) between vMPFC and Serum levels of miR-1202. However, no significant difference was observed in miR-16 levels in the serum of the RC sows and FP sows (p>0.05). Conclusion: This pilot study demonstrates that long-term activity restriction in sows likely results in autism or other complex psychopathies with depression-like behaviors. These observations may provide new insights for future studies on abnormal behavior in sows and contribute to research on human psychopathy.

  • Government support for entrepreneurship has been very useful for many young people who start new ventures to chase their dreams. However, it has constantly been abused by unscrupulous people who intend to take advantage of monetary support. Why do some exploit it, while others make good use of it? It is important to examine the immoral personality traits in potential entrepreneurs, because entrepreneurship affects not only individuals, but also the entire society and country. This study investigates the relationship between negative personality traits and nascent entrepreneurship. Specifically, it examines the effects of the dark triad of personality - narcissism, Machiavellianism, and subclinical psychopathy - on entrepreneurial intention, self-efficacy, and productive and unproductive entrepreneurial motives. We conducted a questionnaire-based survey on university students who intend to start new ventures in the future, while pursuing entrepreneurship education. We analyzed a total of 265 responses. We found that narcissism is the only factor that has a positive influence on entrepreneurial intention. Narcissism has a positive effect on entrepreneurial self-efficacy, while psychopathy has a negative effect. We also found that narcissism has a positive influence on productive entrepreneurial motives, while Machiavellianism has a significant negative influence. Finally, we found that Machiavellianism and psychopathy have a positive impact on unproductive entrepreneurial motives.

  • 본 연구는 사건관련전위를 이용하여 정신병질자들이 정서인식에 따른 반응억제의 어려움이 있는지를 알아보기 위해 수행되었다. 교도소에 수용 중인 수형자들을 대상으로 PCL-R(Psychopathy Checklist-Revised)의 점수에 따라 6명의 정신병질 수형자집단과 4명의 정상 수형자집단을 선별하고, 얼굴자극을 이용한 시각 Go/NoGo 과제를 실시하였다. 모든 피험자들은 Go 자극에 버튼을 누르고 NoGo 자극에 버튼을 누르지 않도록 지시를 받았으며, 과제를 실시하는 동안 사건관련전위를 측정하였다. 과제 1에서는 공포표정을 NoGo자극으로 사용하고 중성표정을 Go자극으로 사용하였으며, 과제 2에서는 슬픈 표정을 NoGo자극으로 사용하고 중성표정을 Go자극으로 사용하였다. 정신병질 수형자집단은 공포표정의 NoGo P3 진폭이 중성표정의 Go P3 진폭보다 크게 나타난 반면에 정상 수형자집단은 공포표정과 중성표정 간의 P3 요인의 진폭이 유사하거나 공포표정의 NoGo P3 진폭보다 중성표정의 Go P3 진폭이 더 크게 나타났다. P3 잠재기를 분석한 결과, 정신병질 수형자집단은 슬픔 표정자극의 NoGo조건에서 중성표정자극의 Go조건보다 느린 P3 잠재기를 나타낸 반면, 정상 수형자집단은 NoGo조건에서 Go조건보다 빠른 P3 잠재기를 나타냈다. 정서인식검사결과, 정신병질 수형자집단은 정상 수형자 집단보다 유의미하게 낮은 정확도를 나타냈다. 이러한 결과는 정신병질자들이 공포, 슬픔과 같은 부정적인 정서를 인식한 후에 반응을 억제하는데 인지적인 어려움을 겪는다는 것을 보여준다.
