In this study, the effect of VR exposure programs integrated with web-based cognitive restructuring education on reducing social anxiety was confirmed. The experimental group (n=12) received a 10~15 minute session of web-based cognitive intervention and a 20-minute session of virtual reality exposure therapy. The comparison group (n=15) received a 10~15 minute session of web-based speech education and a 20-minute session of virtual reality exposure therapy. After 4 weeks, the experimental group had an increase in positive interpretation bias, a decrease in negative interpretation bias, and a decreased level of social anxiety. These results suggest that the combination of self-help form of web-based cognitive intervention in the treatment of social anxiety disorder can improve the therapeutic effect of VRET.

People tend to overestimate their emotional reactions to events such as physical handicap and buying a new car in the future. Students overestimate their reactions to a future grade as compared to their reactions after receiving the grade. Impact bias refers to people's tendency to overestimate the intensity and the duration of emotional reactions to a future event. The present study explored whether impact bias occurs to risky objects such as nuclear energy, genetically engineered food, and mobile phone. Participants were asked to predict their emotional reactions at three time points, that is, at the present, a week after, and a year after. They predicted their reactions before and after two debiasing tasks. The present study demonstrated a different pattern of impact bias at three time points: A largest bias was observed a week after the present. A defocalism manipulation has eliminated the impact bias whereas an adaptation manipulation has not. Several points were discussed regarding the difference between the previous and the present work.

The purpose of the current study is to investigate how task-irrelevant affective priming affects higher cognitive function. In the study, we selected prime stimuli from International Affective Picture System(IAPS) and examined if they influence participants' performance of syllogistic reasoning task when they are task-irrelevant. In Experiment 1, arousal of IAPS stimuli was controlled while valence of the stimuli was manipulated. In Experiment 2, valence of IAPS stimuli was controlled while arousal of stimuli was manipulated. In both experiments, task-irrelevant affective primes were followed by syllogistic reasoning tasks consisting of three sentences and measured accuracies of task performance. The results showed that valence of affective prime affected logical validity of reasoning and belief-bias whereas arousal of affective primes did not yield any difference. That is, positive valence facilitated logical and analytic processing by reducing belief-bias while arousal did not affect reasoning task performance. These results suggest that dimensions of valence and arousal independently influence higher cognitive function.

New media moved the place of social exchange to the Internet, allowing large groups to communicate in one place beyond the limits of time and space. Recent studies have also reported cases in which human social abilities do not keep up with the expansion of group scale through social media. In this context, current study investigated how human perception of social information is affected by the expansion of the group scale in the context of majority bias. Using Internet-based task, the psychological processes that group ratio and group size are perceived and affect majority-biased social information use were investigated, and whether group scale moderates those processes was examined. The group ratio has a positive effect on the majority bias, and the relationship was partially mediated by ratio perception. Group scale did not moderate the relationship between group ratio and ratio perception. On the other hand, the correlation between group size and majority-biased social information use was not significant. Group scale moderates group size perception. The group size and size perception showed positive correlation under the smaller group scale condition. However under the extended group scale condition, the perceived group size became significantly lower and lost its correlation with group size. These results provide evidence that the psychological mechanism related to group size perception was not properly responding to the expansion of the group scale. Furthermore, the possibility of a specific psychological mechanism for processing group size information and the form of information input specifically accepted by majority bias were discussed from perspective of evolutionary psychology.

본 연구에서는 신체상 위협상황에서 대처 전략을 측정할 수 있는 한국판 신체상 대처전략 척도(K-BICSI: The Korean Version of the Body Image Coping Strategy: K-BICSI)를 사용하여 회피 전략을 사용하는 정도에 따라 고회피집단(N=12)과 저 회피집단(N=12)으로 구분하여 실험참가자를 모집하였다. 연구의 목적은 외모 관련 자극이 제시 되었을 때 달라지는 주의편향과 자극 제시 전후의 정서변화를 살펴보는 것이었다. 실험 참가자는 여대생 24명으로, 안구운동 추적장비의 최초 응시방향과 응시시간을 이용해 주의편향을 확인했으며, 정서변화는 VAS로 측정하였다. 분석 결과 고 회피집단은 저 회피집단에 비해 비매력자극에 대한 더 높은 최초응시 경향을 나타냈지만, 매력자극에 대해서는 유의미하게 긴 응시시간을 보였고, 외모관련 지극 제시 전보다 후에 더 유의미하게 정서가 부정적으로 변하였다. 본 연구의 결과로 고 회피집단은 저 회피집단과는 다른 주의 인지기제를 가지고 있으며 외모관련 자극에 정서적으로 민감하게 반응한다는 것을 확인할 수 있었다.

Attention and emotion interact intimately. Anxiety, for example, modifies attentional mechanisms to enhance the processing of threat-related information. But how can it modulate attention? Studies of the emotional Stroop task showed clearly that color naming was interfered with more by negative word distractors than by neutral distractors in anxious participants. However, few studies have investigated in what stage an emotional stimulus biases attention. The present study investigated the locus of interference in the emotional Stroop task by manipulating the SOA (Stimulus Onset Asynchrony) between the word distractor and the color target (0ms, 120ms, or 240ms). Results showed that interference occurred only with 0ms of SOA for anxious participants, whereas for non-anxious participants, there was no interference effect. These results support the view that the attentional mechanism was modulated in early stage of information processing by anxiety.

The goal of this paper is to propose the use of machine learning platforms in education to train learners to recognize data biases. Learners can cultivate the ability to recognize when learners deal with AI data and systems when they want to prevent damage caused by data bias. Specifically, this paper presents a method of data bias education using MachineLearningforKids, focusing on the case of AI baseball referee. Learners take the steps of selecting a specific topic, reviewing prior research, inputting biased/unbiased data on a machine learning platform, composing test data, comparing the results of machine learning, and present implications. Learners can learn that AI data bias should be minimized and the impact of data collection and selection on society. This learning method has the significance of promoting the ease of problem-based self-directed learning, the possibility of combining with coding education, and the combination of humanities and social topics with artificial intelligence literacy.

시스템 다이내믹스는 인과지도(Causal map)를 통한 시스템 이해를 그 출발점으로 한다. 특히 시스템 사고(systems thinking)는 저량-유량 흐름도를 통한 컴퓨터 시뮬레이션을 통하지 않고서 인과지도 분석만을 통한 시스템의 이해를 시도한다. 그러나 과연 인파지도만을 가지고 시스템을 동태적 변화를 이해/예측할 수 있는가에 관하여는 낙관적 전망과 부정적 전망이 혼재되어 있는 상황이다. 본 연구에서는 인과지도 구축을 통하여 시스템의 변화를 이해하는 데 있어서 어떠한 인지적 편향(bias)이 개입되는지를 탐색하고자 한다. 만일 심리적 편향이 존재한다면. 시스템 사고는 오류로부터 자유로울 수 없을 것이다. 본 연구에서는 이러한 오류의 존재를 탐색함으로써 시스템 사고의 제한정과 그 극복방안에 관하여 논의하고자 한다.(중략)

Behavior Economics, a branch of social sciences, which seeks to find the answers about why man sometimes does absurd economy-related things, came into existence through combining economics and psychology. To the contrary of the traditional economics', behavior economics has developed by explaining how man makes economy-related choices by means of applying their own cognitive principles. Individuals lack the information on the goods and services in the market, and don't know how to make best use of the obtained information, failing to achieve maximum utility. Therefore, man's rationality is meant to be confined to bounded rationality. It is the very Heuristic that does work in the process of this simplified decision making process. Heuristic utilizes established empirical notion and specific information, and that's why there can be cognitive biases sometimes leading to inaccurate judgment. As Oral Literature is basically based on heavy guesswork and perceptual biases of general public, it is imperative to contemplate oral literature in the framework of Heuristic of behavior economics. This thesis deals with thinking types and behavioral patterns of the short-piece proverbs, folklore language-game riddles on the basis of personal or public memory. As a result, it is evident that proverbs point out biases arising from human behaviors, while riddles make full or active use of biases.

공간적 관계정보(spatial relation)가 언어적 표상시스템과 비언어적 표상시스템에서 어떻게달라지는가를 범주화 모델의 원형이론 모델을 적용하여 알아보고자 하였다. 이전의 연구들에 따르면 공간적 관계정보에 대한 프로토타입이 언어적 범주와 비언어적 범주에서 다르다는 연구 결과(Crawford 등 2000, Huttenlocher 등 1991)와 동일하다. (Hayward & Tarr 1995)는 상반된 연구 결과가 제기되고 있다. 하지만 이전 연구들에서의 문제점은 언어/비언어 표상체계 간의 편향을 통제하지 못했기 때문에 과제에 따라 서로 다른 결과가 나온 것이라고 볼 수 있다 본 연구에서는 두 대상간의 관계정보를 문장으로 제시한 조건, 그림으로 제시한 조건, 그리고 두 조건을 혼합한 조건을 사용하여 편향에 의한 효과를 제거하고자 하였다. 실험은 각 조건에 따라 짝으로 구성된 자극을 학습한 후 검사자극을 공간적 관계정보를 다양하게 하여 학습자극과 동일한지 아닌지를 판단하게 하였다. 실험결과 관계정보를 언어적으로 제시한 조건과 비언어적으로 제시한 조건간에 대상의 위치에 따른 반응시간의 경향성에서 차이가 없었으며, 대상이 단어인지 그림인지에 따라서 반응시간에서 통계적으로 차이가 나타났다. 그리고 두 표상체계에서 공간적 관계에 대한 프로토타입을 분석한 결과 수직축을 중심으로 전형성 효과가 나타나는 것을 알 수 있었다.
