Three studies were conducted to examine the degree to which three common heuristics, anchoring heuristic, framing effect and representative-ness heuristic, influence the decision-making precesses of actual judges and 5-persons mock juries. With scenarios regarding various issues that are commonly raised in actual criminal and civil trials, study 1 examined the 158 actual judges' decisions. In study 2, the decisions of 80 mock jury groups that consisted of college students were examined with similar scenarios. And individual decisions were examined in study 3 to compare with the group decisions in study 2. The decision processes of the actual judges and the mock jury groups alike were found to be influenced by "anchors". But the biases by the anchoring heuristic were more pronounced in the group decisions than in the decisions of the actual judges. With respect to framing effect, the actual judges were found to be resistant, while a small effect was found in the decisions of mock jury groups. Representative-ness biases weren't found in the decisions of both the actual judges and mock juries. The implications of the results for judicial systems were discussed.

본 논문은 교통사업들의 투자우선순위 결정시 적용 가능한 방법을 제시한다. 지금의 평가방법을 부정하는 새로운 방법이라기보다는 기존의 평가방법을 보완하는 기법이다. 특히 특성이 다른 교통사업들간의 평가시 이들 특성들이 평가과정에 감안되지 않을 경우는 평가결과의 대외 설득력이 부족하게 된다. 이를 극복하기 위해 지금까지 각종 정량적 정성적 방법을 동원하였지만 그 범위와 방법에 한계가 존재하였다. 이를 보완하는 대안으로서 본 논문에서는 기존 평가과정에서 고려되기 어려운 사업의 여러 특성들을 전문가들의 경험과 판단을 통해 최대한 반영하는 방법을 제시한다. 이 기법의 기본 이론은 집단의사결정이론(group decision theory)이며, 여기에 퍼지이론이 접목된 퍼지집단 결정이론(fuzzy group decision theory)을 적용하였다. 이 이론은 개인의 대안별 선호(우선순위)로부터 집단의 선호관계(우선순위)를 도출할 수 있다. 또한 도출된 투자우선순위결과에 대한 집단의 동의수준(만족도)을 추정할 수 있다. 이러한 정보는 최종 정책결정자의 중요한 판단자료로서 사용되어 질 수 있다. 그 동안 교통사업의 투자우선순위결정과정의 객관성의 부족으로 사업간 우선순위결과에 대한 신뢰가 그리 높지 않았다. 본 논문에서 제시한 방법은 기존의 투자우선순위의 평가방법을 보완하여 대외적인 신뢰성을 제고할 수 있을 것으로 판단된다.

Phonological awareness is a metalinguistic awareness ability of phonology and is known to predict language skills, such as reading and vocabulary skills. The purpose of this study was to investigate the relationship between phonological awareness, phonological processing, and language skills in 4- to 6-years-old typically developing (TD) children and children with language delay (LD). A total of 32 children (TD=18, LD=15) participated in this study. They performed a phonological awareness task consisting of counting, deletion, and discrimination at syllable level. Nonword Repetition, Digit Backward, Receptive & Expressive Vocabulary Test, and Grammaticality Judgment Task were performed to analyze the correlation between phonological awareness, phonological processing, and language ability. A multiple stepwise regression analysis was performed to examine the phonological awareness subtasks that predict language ability. In the TD group, the syllable categorization task significantly predicted the receptive vocabulary and the performance of the Grammaticality Judgment Task. The LD group showed that the syllable counting task significantly predicted the receptive vocabulary, the expressive vocabulary, and the performance of the Grammaticality Judgment Task. The results showed that the phonological awareness performance was significantly different between the two groups. Further, correlation analysis and regression analysis showed different results for each group. The result of the phonological awareness performance predicted the language ability of each group significantly, suggesting the importance of the meta-linguistic awareness ability of phonology.

Do cultural differences affect moral decisions? Two studies were conducted to investigate whether attitudes of individualism vs. collectivism have an impact on ethical decision making. Study 1 (N=92) showed that utilitarianism was preferred in a situation, in which an intervention resulted in the best outcome (i.e., saving more people's lives), while deontology was preferred in a situation, in which the focus was on negative consequences of the intervention (i.e. personal sacrifices). Additionally, there were differences between the idiocentrics and the allocentrics groups regarding morality aspects. In the idiocentrics group, harm and fairness were regarded as more important than other moral aspects, while in the allocentrics group, not only harm and fairness, but also ingroup and authority were perceived as critical moral aspects. In Study 2 (N=30), after lexical decision tasks were conducted for culture priming, the mouse tracking method was used to explore response dynamics of moral decision processes, while judging appropriateness of interventions in moral dilemmas. In Study 2, in a condition, in which the small number of victims were focused upon, there were more maximal deviations and higher X_flips in the individualism priming group than in the collectivism priming group, which showed that the participants in the individualism condition had more deliberative processes before choosing their answers between utilitarianism and deontology. In addition, the participants in the individualism priming condition showed more maximal deviations in the mouse trajectories regarding ingroup related interventions in moral dilemmas than those in the collectivism priming condition. These results implicated the possibilities that the automatic emotional process and the controlled deliberative process in moral decision making might interact with cultural dispositions of the individuals and the focus of situations.

본 연구는 다변량 통계분석을 이용하여 자동차사고성향에 대한 공통적인 특성을 찾아내고 그것이 심리적 성격특성과 관련이 있는가를 분석하고자 수행되었다. 이를 위하여 학생집단, 일반인집단 그리고 운전기사집단의 성격적 특성과 자동차사고경험 혹은 그 가능성을 비교 검토하였다. KG식 일반생활질문지에 의한 설문분석결과에 따르면 사고친화성향에 따라 2개의 집단으로 분류하는 것이 타당하다고 판단되었고, 수량화분석에 의해서도 집단을 구분할수 있었지만 일반인과 운전자 집단간에는 차이가 있었다.

The purpose of this study is to analyze and compare the effectiveness of elementary in e-Learning video lessons. In an elementary school where the educational videos are frequently used, the learning about video materials is important but it is difficult to judge all students by a teacher in a classroom. In order to solve the problems of the field, In the fifth-grade elementary school social studies class, learning using video material was conducted by using the online learning judgment system for the experimental group, and learning using video material was conducted by the traditional method for the controlled group. As a result of the experiment, the class using the online learning judgment system was effective in enhancing the learner 's academic achievement. It also positively influenced learners' learning satisfaction. Teachers' satisfaction was not statistically significant because of the small number of teachers. However, The mean value of the teachers' satisfaction in the experimental group was high and the deviation was small.

Judgment and decision-making studies have shown that people are easily influenced and biased by information irrelevant to the object of judgment. There is a great deal of research that indicates that bias exists in the legal judgment scene. One of them is a bias induced by defendants' character evidence. This study examined whether cognitive activities such as discussion, counterfactual thinking, and peer assessment could reduce the bias induced by the character evidece. In Experiment 1, 121 college students were asked to give the percentage they believed the defendant to be guilty. There was no cognitive activity for the control group. There were three different cognitive activities for the experimental group: discussion, counterfactual thinking and discussion, and counterfactual thinking and peer assessment. Results showed reduction in bias for all the experimental groups, and there was no difference between them. In Experiment 2, there were 125 participants from general population for the same procedure as in Experiment 1. Results showed reduction in bias only for the counterfactual thinking and discussion group. In general discussion, we speculated the implication of the results and the reason for the difference between the two experiments.

This study examined the differences in facial emotion processing related to psychopathic traits. On the basis of the Psychopathic Personality Inventory-Revised (Lee & Park, 2008), students were divided into psychopathic trait (n=15) and control (n=15) groups. Participants performed two tasks consisted of negative(angry, fear, sad) and neutral faces. Event-related potentials(EPRs) were recorded when participants categorized gender in the implicit task and emotion in the explicit task. We analyzed the late positive potentials(LPP) amplitude to investigate differences in emotion processing between psychopathic trait group and control group. In the implicit task, there was no significant difference in both groups. However, there was a significant interaction between emotion and group at the frontocentral region in the explicit task. The psychopathic trait group showed greater LPP amplitudes for the neutral faces than for the negative faces, whereas the control group showed similar LPP amplitudes for the neutral and negative faces at the frontocentral site. These results might reflect the abnormalities in emotional processing in individuals with psychopathic traits.

양계업이 대형화되면서부터 사양관리의 관점은 닭을 개체로 보지 않고 계군 즉 집단으로 판단하고 있다. 그러나 개체로 분류하여보면 계군으로 나타난 통계에 의한 관리가 부분적으로 불합리함을 알게된다. 축산업은 그것이 생명을 다루는 한 개체관리의 관점에서부터 시작되어야 한다. 경영관리에서는 계군을 한 개 집단으로 처리하더라도 기술관리는 닭의 개체에서부터 전체로 진행해야하는 것이다.

Gunnar Myrdal has struggled throughout his academic life with the problem of the role of valuations in social sciences. His earlier viewpoint was that valuations should be completely separated from scientific analysis on facts. But he soon fundamentally changed his viewpoint. His later viewpoint was that social scientists should disclose his valuations, for valuations intervene all the processes of scientific researches. Value premises are the valuations coherently reconstructed and manifestly articulated. Myrdal argued that social scientists should disclose value premises and perform his analysis and normative judgement based on the value premises. And the value premises should be derived from the valuations held by the large or significant groups of the society under study, not from the researcher's own valuations. This paper tried to show that Myrdal's later viewpoint must meet the crux, that researcher's own viewpoint must intervene in choosing valuations of particular group among diverse groups in the society under stduy, and in deriving and reconstructing value premises from the valuations of that group. And it argued that the reason why Myrdal met the crux could be explained by that he accepted the emotivism of Axel $H{\ddot{a}}gersr{\ddot{o}}m$. And it proposed some methodological solutions for escaping the crux Myrdal met, while preserving the positive elements of Myrdals' viewpoint.
