신영은 ( Young-eun Shin ),민윤기 ( Yoonki Min ),이영창 ( Young-chang Lee ) 한국감성과학회 2021 감성과학 Vol.24 No.1

본 연구는 생각/생각회피 과제를 이용하여 의도적 생각회피, 즉 생각억제와 생각대체의 효과를 종합적으로 검증하였다. 이를 위해 연관성이 높지 않은 2음절 단어자극을 선정하고, 단일집단을 대상으로 회상조건(단서회상, 표적회상)과 훈련조건(생각, 생각억제, 생각대체, 기저선)의 정확회상률을 비교하였다. 그 결과, 훈련조건과 관계없이 표적회상에 비해 단서회상의 정확기억률이 높은 것으로 나타났으며, 회상조건과 관계없이 다른 조건에 비해 생각조건의 정확회상률이 높은 것으로 나타났다. 또한 회상조건과 훈련조건의 상호작용 효과의 경향성이 나타났으며, 세부적 검증 결과. 생각억제의 경우, 회상조건 간 차이가 나타나지 않은 반면에 생각대체의 경우에는 표적회상에 비해 단서회상의 정확기억률이 높은 것으로 나타났다. 이러한 결과는 생각억제와 생각대체전략이 모두 의도적으로 생각을 회피하는데 효과적이라는 것과 더불어 생각억제와 생각대체전략이 서로 다른 원리에 의해 발생할 수 있음을 시사한다. This study examined the effect of intentional thought avoidance(i.e., thought suppression and thought substitution) using “Think and No Think” task. Two syllable words were selected, and recall test was performed with a single subject group. recall accuracy of them was measured in two recall conditions(cue recall and target recall) and four training conditions(thought, thought suppression, thought substitution, and baseline). The results showed that recall accuracy in cue recall condition was better than in target recall condition, regardless of training conditions, and recall accuracy in thought condition was better than in other training conditions, regardless of recall conditions. Also there was significant interaction between recall and training conditions: For thought suppression. there was no difference between two recall conditions, whereas for thought substitution, recall accuracy in cue recall condition was better than in target condition. These findings indicate that thought avoidance strategies, including both thought suppression and thought substitution, are effective in avoiding the specific thought intentionally, and thought suppression and thought substitution could be applied by different mechanism.

맥락 단서 효과를 활용한 PIN 인증 시스템 제안

PIN(Personal Identification Number)은 과거부터 금융거래에서 개인을 인증하는 방법으로 많이 사용되어 왔으며, 아직까지 사용자에게 가장 익숙한 인증 방식이다. 그러나 PIN 인증 방식은 모바일 특성상 훔쳐보기(Shoulder-surfing)에 취약하며, PIN 번호만 알고 있다면 누구든지 접근이 가능하다는 단점이 있다. 따라서 본 연구는 맥락 단서효과(contextual cueing effect)를 활용하여 비사용자의 접근이 불가능한 새로운 PIN 인증시스템의 실현 가능성에 대해 알아보고자 하였다.

Vishing (voice phishing) is a common form of social-engineering attack directed at humans. The cost of vishing attacks has gradually increased since the first case occurred in 2006. Although the number of cases has recently declined due to the precaution policy introduced by the Korean government, the amount of damage per victim has risen and new casesinvolving novel vishing methods have appeared. The present study investigated not only the current extent of damage in Korea but also the psychological vulnerability of victims. Results found the relation between major vishing tactics and psychological triggers behind social engineering.Little evidence of behavioral study, however, was conducted for investigating the relationship. Therefore, we suggest the direction of a post study that can validate the relationship between psychological triggers and vishing.

탐색 자극의 시각적 특징이 공간적 배열의 맥락 단서 학습에 미치는 영향

장유리(Yuri Jang),정고은(Koeun Jung),민윤기(Yoonki Min) 한국자료분석학회 2020 Journal of the Korean Data Analysis Society Vol.22 No.4

방해 자극들 사이에 표적 자극이 제시되는 시각 장면에 반복적으로 노출될 때, 우리는 표적의 위치와 방해 자극의 공간적 배열 사이의 연합을 학습할 수 있다. 따라서 표적을 탐색하는 속도는 새로운 화면보다 반복 화면에서 더 빠르며, 이러한 탐색 시간의 이득을 맥락 단서 효과(Contextual cueing effect)라고 한다. TL 탐색 과제를 사용한 맥락 단서 효과는 주로 자극들의 공간적 배열로 정의되어 왔으나, 실제 물체 탐색 과제를 사용한 최근 연구들에서는 맥락이 자극들의 공간적 배열과 시각적 특징의 합으로 정의된다고 제안하고 있다. 본 연구에서는 공간적 배열맥락이 시각적 특징 맥락보다 더 강할 때, 시각적 특징 맥락이 공간적 배열 맥락 단서의 학습에 어떤 영향을 미치는지 알아보고자 하였다. 연구 1(물체 탐색)과 연구 2(TL 탐색)는 공간적 배열의 독립적 학습과 이에 시각적 특징 맥락이 더해지는 효과를 보여주었다. 그러나 맥락 단서의 학습은 두 과제에서 다르게 나타나지 않았다. 따라서 과제에 따라 맥락 단서의 학습이 다르게 나타나는 것이 아니라 표적의 위치를 예측해주고 연합장벽(associative blocking)이 발생하지 않을 때 맥락 단서에 대한 학습이 발생한다는 것을 확인하였다. When visual displays in which a target is presented among distractors are repeatedly presented, we able to learn the association between the spatial configuration of distractors and target’s location. Search speed is faster in the repeated displays than in the novel displays. This benefit of search time is called the Contextual cueing effect. The contextual cueing effect using the TL search task has been defined primarily as a spatial configuration of stimuli, but the recent studies by Makovski(2016, 2018), using the real-world object search task, suggest that the context is the sum of the spatial configuration and visual features of stimuli. Therefore, the goal of this study was to investigate how the context of visual features affects the learning of context of spatial configuration when the context of spatial configuration is stronger than the context of visual features. Study 1(using the real-world search task) and Study 2(using the TL search task) showed the independent learning of spatial configuration and the additive effect of the context of visual features. Also, the learning of contextual cue did not differ between the two tasks. These results suggest that the learning of contextual cue not depends on task, but it is possible when the contextual cues can predict the target location and associative blocking does not occur.

The present study sought to investigate the research trends related to the cognitive benefits of bilingualism and propose research directions by identifying factors influencing these benefits. Using the Google Scholar, ScienceDirect, and Scopus databases, 55 original studies published in the last 18 years (from 2005 to June 2023) were selected. of the selected literature, 47% showed results supporting the cognitive benefits of bilingualism, 20% reported mixed results, and 33% reported results that did not supporting cognitive benefits. Previous studies proposed various factors that could explain inconsistent research results, such as participant selection, diversity of cognitive sub-components, cultural differences, language use environment, and similarity between the two languages. Based on these findings, the present study discussed the considerations and research designs that should be considered for the confirmation of the cognitive benefits of bilingualism.

재인방식을 통한 틀린인출시도가 추후의 기억에 미치는 영향

This study examined whether the memory enhancement effect by unsuccessful retrieval occurs even when recognition tests are used in the course of learning, and whether the effect varies according to the final memory test method. To this end, they were divided into a read-only group, cue-presented group, and unsuccessful retrieval group according to the final memory test method, and the final test group was divided into the recognition test group and recall test group. All groups of participants performed a recognition study section consisting of word-pair learning processes and distractor task section. Finally, accurate memory rates were measured using a recognition and recall method. The results showed that the accuracy of the recognition final test method was higher than that of the recall method, and that the cue-presented group had a higher accuracy than the read-only study group and the unsuccessful retrieval group. These results contrast with a number of studies that verified the test effects of the recall method, suggesting that the effects of unsuccessful retrieval in the learning process might have different effects on the recognition method and recall method.

기억재료의 연관성에 따른 틀린인출의 기억촉진효과

이영창(Youngchang Lee),이현진(Hyunjin Lee),방혜영(Haeyoung Bang),곽진선(Jinseon Kwak),민윤기(Yoonki Min) 충남대학교 사회과학연구소 2015 사회과학연구 Vol.26 No.4

This research is conducted to confirm whether unsuccessful retrieval has the memory enhancement effect, especially how the memory enhancement effect is changed according to connectivity between memory materials. For this purpose, the participants were divided into two study groups including reading only group and unsuccessful retrieval group, and learned 20 high connectivity word pairs and 20 low connectivity word pairs. All participants conducted both immediate and delayed retrieval tests after learning word pairs. The results of this research show that the recollection rate of final memory test was different according to the study groups and the connectivity of word pairs. Specifically the accuracy of final memory test was higher in unsuccessful retrieval group than reading only group in high connectivity condition but in low connectivity condition. This result means that memory enhancement effect of unsuccessful retrieval can be differed by the semantic features of memory materials.
