  • Objective: The aim of this study is to investigate effect of driver's cognitive distraction on driver's physiological state and driving performance, and then to determine parameters appropriate for detecting the cognitive distraction. Background: Driver distraction is a major cause of traffic accidents and poses a serious threat to traffic safety due to ever increasing use of in-vehicle information systems and mobile phones during driving. Cognitive distraction, among four different types of distractions, prevents a driver from processing traffic information correctly and adapting to change in surround vehicle behavior in time. However, the cognitive distraction is more difficult to detect because it normally does not involve significant change in driver behavior. Method: A full-scale driving simulator was used to create virtual driving environment and situations. Participants in the experiment drove the driving simulator in three different conditions: attentive driving with no secondary task, driving and conducting secondary task of adding numbers, and driving and conducting secondary task of conversing with an experimenter. Parameters related with driver's physiological state and driving performance were measured and analyzed for their change. Results: The experiment results show that driver's cognitive distraction, induced by secondary task of addition and conversation during driving, increased driver's cognitive workload, and indeed brought change in driver's physiological state and degraded driving performance. Conclusion: The galvanic skin response, pupil size, steering reversal rate, and driver reaction time are shown to be statistically significant for detecting cognitive distraction. The appropriate combination of these parameters will be used to detect the cognitive distraction and estimate risk of traffic accidents in real-time for a driver distraction warning system.

  • The distraction of the driver's attention causes as much traffic accidents as drowsiness driving. Yet though there have been many studies on drowsiness driving, research on distraction driving is insufficient. In this paper, we divide distraction of attention into visual distraction and cognitive distraction and analyze the EEG of subjects while viewing images of distracting situations. The results show that more information is received and processed when distractions occur. It is confirmed that the probability of accident increases when the driver receives overwhelming amount of information that he or she cannot concentrate on driving.

  • This article reports some Korean EFL learners' cognitive tendencies drawn up from their responses to logical fallacies in the argument passages, and its pedagogical implications. The findings of experimental study show the meaningful disparities in three sets of judgment tests designed to identify and explicate faulty arguments: based on the three general types of fallacies using language, emotions, and distraction tactics, subjects on average gained the highest scores in the test questions with language-loaded fallacies and the lowest scores in those with emotion-based ones among the three different types; for this reason, the scores that subjects obtained in the test of distraction-loaded fallacious arguments fell in between the two poles. These discrepancies, mainly based on statistical inferences, support the possibility that the Korean EFL learners are most likely to be manipulated by emotions/distraction- loaded argument tactics than by language-based ones in the three types of fallacious arguments; and, they are least likely to be influenced by language-oriented trickeries. As a consequence, such variances in abilities to recognize the intrinsic elements of logical fallacies suggest some basic instructional approaches to critical reading of argumentative texts with due weights on the Korean EFL learners' culture-specific cognitive tendencies.

  • Driving workload is increasing according to developing new in-vehicle devices and introducing driving information systems. In this research using a driving simulator, EFRP (Eye Fixation Related Potential) was measured for evaluating driving attention and distraction while tasking cognitive workload, n-back tasks. The result of EFRP was compared with driver behaviors. Results suggest that EFRP is able to use for a method of evaluating driving workload, however, the analysis of driver behavior is difficult to find driving attention and distraction in the case of free flow of traffic situation.

  • The purposes of this study were firstly, to examine the emergence of complex strategies for emotional regulation in 3 and 4 years old children, and secondly, to analyze the corresponding relationship of the preschoolers' strategies for emotional regulation and their mothers' responses. The subjects comprised 66 preschoolers(33 boys, 33 girls) and their mothers in J city. The results were as follows. First, the preschoolers' strategies for emotional regulation in frustrating episodes occurred in the following order; instrumental behaviors, cognitive reappraisal, distraction behaviors, and comforting behaviors. Second, the mother's responses to frustrating episodes occurred in the following order; cognitive reappraisal, instrumental behaviors, comforting behaviors, and distraction behaviors. Third, the corresponding relationship of the preschooler's strategies for emotional regulation and the mothers' responses to frustrating episodes were found to be of a similar patterns (e.g. preschoolers' cognitive reappraisal strategy and mothers' cognitive reappraisal response).

  • 이 연구는 집중산만 전략을 활용한 건강염려증의 해소 방안을 모색하는 문헌연구이다. 건강염려증은 우리말로 건강기우증, 건강불안, 질병공포, 질병불안장애, 건강염려성 신경증, 건강염려성 성격장애, 신체 증상장애 등의 용어로 불리워지나 이 연구에서는 건강염려증으로 명명한다. 이는 기본적으로 염려, 두려움, 불안 더 나아가 공포를 야기하여 가정, 직장 및 사회에서 삶의 질을 저하하게 만드는 요인이다. 건강염려증은 주로 중년기 성인들이 겪는 심리적 문제로서 자기자신에게 집중, 몰두하다가 이에 노출된다. 이 증상은 건강에 대한 지나친 염려로 인해 빈번한 건강검진 등 병원을 전전하면서 상당한 사회적 비용이 소비되고, 개인의 삶의 질이 저하되어 상담심리, 심리상담 분야에서는 이 문제를 해결해주고, 심리적 평안을 회복하도록 해야 하는 과제를 안고 있다. 따라서 이 연구는 건강염려증을 해소할 수 있는 방안으로 인지 전략 가운데 집중산만 전략을 활용하여 그 증상 해소를 모색해보려는 시도라 할 수 있다. 집중산만 전략은 일종의 인지적 '회피 전략'이라 할 수 있다. 자신의 건강에 대하여 지나치게 집중하는 인식, 주의를 회피, 다른 방향으로 '분산'시키거나 '산만'하게 하는 것으로 건강염려를 약화시키는 것이다.

  • Driving is a complex psychomotor task often interrupted by secondary activities that increase cognitive workload and divert attention away from the roadway. The risk of inattentive driving is known to vary with age. To assess the characteristics of advancing age on driver's cognitive workload under dual task condition, we evaluate the performance of 96 drivers divided into three age groups: 20's, 40's, and 60's. This study considers driver's cognitive workload in the context of urban and highway driving. Error rate & Dual task cost are used to measure driver's cognitive workload. Results indicate that age impacts cognitive workload during dual task driving conditions.

  • Background: Experience of lung cancer includes negative impacts on both physical and psychological health. Pain is one of the negative experiences of lung cancer. Cognitive behavioral therapy techniques are often recommended as treatments for lung cancer pain. The objective of this review was to synthesize the evidence on the effectiveness of cognitive behavioral therapy techniques in treating lung cancer pain. This review considered studies that included lung cancer patients who were required to 1) be at least 18 years old; 2) speak and read English or Thai; 3) have a life expectancy of at least two months; 4) experience daily cancer pain requiring an opioid medication; 5) have a positive response to opioid medication; 6) have "average or usual" pain between 4 and 7 on a scale of 0-10 for the day before the clinic visit or for a typical day; and 7) able to participate in a pain evaluation and treatment program. This review considered studies to examine interventions for use in treatment of pain in lung cancer patients, including: biofeedback, cognitive/attentional distraction, imagery, hypnosis, and meditation. Any randomized controlled trials (RCTs) that examined cognitive behavioral therapy techniques for pain specifically in lung cancer patients were included. In the absence of RCTs, quasi-experimental designs were reviewed for possible conclusion in a narrative summary. Outcome measures were pain intensity before and after cognitive behavioural therapy techniques. The search strategy aimed to find both published and unpublished literature. A three-step search was utilised by using identified keywords and text term. An initial limited search of MEDLINE and CINAHL was undertaken followed by analysis of the text words contained in the title and abstract, and of the index terms used to describe the article. A second search using all the identified keywords and index terms was then undertaken across all included databases. Thirdly, the reference list of all identified reports and articles were searched for additional studies. Searches were conducted during January 1991- March 2014 limited to English and Thai languages with no date restriction. Materials and Methods: All studies that met the inclusion criteria were assessed for methodological quality by three reviewers using a standardized critical appraisal tool from the Joanna Briggs Institute (JBI). Three reviewers extracted data independently, using a standardized data extraction tool from the Joanna Briggs Institute (JBI). Ideally for quantitative data meta-analysis was to be conducted where all results were subject to double data entry. Odds ratios (for categorical data) and weighted mean differences (for continuous data) and their 95% confidence intervals were to be calculated for analysis and heterogeneity was to be assessed using the standard Chi-square. Where statistical pooling was not possible the finding were be presented in narrative form. Results: There were no studies located that met the inclusion requirements of this review. There were also no text and opinion pieces that were specific to cognitive behavioral therapy techniques pain and lung cancer patients.Conclusions: There is currently no evidence available to determine the effectiveness of cognitive behavioural therapy techniques for pain in lung cancer patients.

  • 본 연구는 좌절 상황에서 3세 유아가 보이는 정서조절 전략의 양상을 살펴보고, 유아의 전략과 그에 반응하는 어머니의 전략 간의 상관을 알아보는 것을 목적으로 한다. 만 3세 유아와 어머니 33쌍을 대상으로 한 실험 관찰을 실시하였다. Stansbury와 Sigman(2000)의 도구를 한국의 문화적 실정에 맞춰 수정 보완하여 사용하였는데, 이 도구는 2개의 좌절 상황에서 유아의 정서조절 전략과 어머니의 반응 전략을 위안, 도구, 인지 재평가, 주의전환, 기타의 5가지로 구분한다. 연구 결과, 3세 유아들은 인지 재평가를 포함한 복잡한 전략을 사용하는 것으로 나타났다. '장난감 정리 과제'(Clean-up) 좌절상황에서는 도구적 전략을 가장 많이 사용하였고, '사탕 지연 과제'(Candy given then denied)의 상황에서는 주의전환 전략을 가장 많이 사용하였다. 유아의 정서조절 전략과 어머니의 반응 전략 간에는 유의미한 정적 상관관계가 나타났다.
