도구추론에서 읽기범위에 따른 개인차 효과가 나타나는지를 살펴보고자 2개의 실험을 수행하였다. 실험 1에서 어휘판단과제를 사용한 결과 읽기범위가 큰 이해자는 도구추론을 온라인으로 생성하였지만, 읽기범위가 작은 이해자는 도구추론을 온라인으로 생성하지 못하는 것으로 나타났다. 그림명명과제를 사용한 실험 2 에서는 읽기 범위에 관계없이 도구추론이 온라인으로 생성되는 것으로 나타났다. 실험 1과 2의 상반된 결과를 종합해 보면, 언어이해과정에서는 발생하는 도구추론의 유형은 언어적인 도구추론과 시각적인 도구추론으로 구분할 수 있으며, 어휘판단과제는 언어적 추론에 민감한 과제인 반면, 그림명명과제는 시각적 추론에 매우 민감함 과제인 것으로 해석할 수 있다. 이러한 결과는 읽기범위가 작업기억의 음운루프 모듈에서의 처리효율성을 반영하는 측정치라는 점을 시사한다.

Human does information processing more efficiently using mental model at his understanding process. if We know what mental model is, we will know how to percept that. Similarly is it used visual mental model to percept visual object\ulcorner If it is true, we will analysis how man to understand. In this research, we have one experimentation to timid out that is true. So we did experimentation to know how man to understand new products by visual mental model. So we use 2700cc car's side view as stimuli. To A Subjects, we give them to see re\ulcorner size view before 120% ratio. To B Subject, we give them to see 120% ratio. After a experimentation, It is true that we make hypothesis that A Subjects percept this stimuli too long then B Subjects. Accordingly it proves human to use visual mental model to percept visual object. The result of experimentation, a testee use preliminary stimulus as basis of evaluation. It means that he use mental model as basis of evaluation of main stimulus. Accordingly development of new design can afford more strategic approach. Industrial designer who want to strategic approach can forced on high-weighted form attribute as consumer gives.

This experimental research explores effect of cognition desire as audience's factor, and attention as context factor on audience's acquirement of information and understanding. Most previous researches of media effect focuses on news contents of TV, Newpaper and Internet. However the number of researches on TV documentary which contains lots of information very limited, and It's difficult to find researches on effect of cognition desire and attention on audience. Therefore this research tries to find effect of cognition desire and attention on audience's acquirement of information and understanding through experiment of TV current documentary. For this experimental research, 2 groups of subjects composed of 135 university students were exposed to 2 different viedeo clips of TV current documantary, one with window buzz, the other without it, after designing cognition desire as internal factor of 2 groups. Questions which were designed to measure cognition desire, acquirement of information and understanding of message were asked and analysed. This research found that subjects with higher degeree of cognition desire showed higher degree of acquirement of information and understanding than subjects with lower degree of cognition desire. However the effect of attention on audience's acquirement of information and understanding could not be found.

An experiment was conducted to investigate the effect of three types of prior knowledge (domain related knowledge, summary-writing strategy knowledge, and neutral unrelated knowledge) and two types (analytic and wholistic) of cognitive styles on the quality of the summary writing of a descriptive text. The results showed that learning domain-related knowledge and summary-writing-strategy knowledge increased the level of understanding of the target text and the quality of the summary; the former operating mainly at the understanding phase, and the latter operating mainly during the summary planning and producing phases. The effect of the types of cognitive style was found somewhat limited but mainly operating In the process of planing the summary. Other features of time course in writing a summary were further discussed.

This study seeks to verify how empathic concern and perspective-taking predict happiness by investigating the mediating effects of cognitive reappraisal. Online surveys about empathic concern, perspective-taking, cognitive reappraisal, and happiness were conducted by 336 adult subjects. First, the correlation analysis indicated that empathic concern and perspective-taking significantly predicted cognitive reappraisal and happiness, respectively. Second, cognitive reappraisal also significantly predicted happiness. Third, the cognitive reappraisal mediated the association between empathic concern and happiness and between perspective-taking and happiness. Specifically, people who emotionally and cognitively empathize with others reported higher levels of cognitive reappraisal, which allowed them to experience higher levels of happiness. These findings have confirmed that people can increase their happiness by enhancing cognitive reappraisal through emotional and cognitive empathy. Finally, the implications and limitations of the present research are discussed.

Websites support various user activities in a wide range of contents domain and so they require different approach to extract principal design problems. In the point of media perspective on websites, this paper figures out the relationship between designer, user and website and discusses design factors of usability. It aims for the basic framework for interface design. In the media perspective website is an information entity mediating user and designer. Information entity is composed of various design factors relating to user, designer, website and others. It intends that user and information entity are accommodative to each other and have common conceptual model. To do so it is necessary for achieving usability objectives such as effectiveness, efficiency and satisfaction based on the understanding user goal, cognitive and affective characteristics. In the point of usability we examine design factors and features that are appropriate for users cognitive and affective function according to information entity model that constitutes contents, organization and representation level.

The purpose of the present study is twofold: one is to understand secondary mathematics teachers' capacity to sort out given tasks based on Stein & Smith(1998)'s Cognitive Demands of Mathematical Task Framework; the second is to examine how the teachers assess the levels of cognitive demand indicated in students' reponses and how they modify the tasks to elicit the students' higher levels of cognitive activity. The analysis of 45 teachers' responses to the survey indicates that the teachers, in general, could select appropriate tasks for the given goal of the lessons but some made the decision merely by their appearances. Even though the teachers chose a particular level with different reasons amongst each other, most teachers could correctly evaluate the levels of cognitive demand of the students' responses. Finally, teachers could pose cognitively demanding tasks using various methods, but a number of them felt challenged in creating word problems that were realistic and aligned with curriculum.

In this study, we investigated the influences of cognitive conflict and situational interest induced by a discrepant event and an alternative hypothesis, attention and state learning strategies on conceptual change. A preconception test was administered to 486 seventh graders. They also completed the questionnaires of cognitive response and situational interest to a discrepant event before/after presenting an alternative hypothesis. After learning the concept of density with a CAI program as conceptual change intervention, the tests of attention, state learning strategies, and conceptual understanding were administered as posttests. Analyses of the results for 197 students having misconceptions about density revealed that post-cognitive conflict was significantly higher than pre-cognitive conflict. However, there was no statistically significant difference between the test scores of pre-situational interest and post-situational interest. Pre-cognitive conflict only exerted a direct effect on post-cognitive conflict, while post-cognitive conflict exerted a direct effect and Journal of the Korean Chemical Society an indirect effect via attention on conceptual understanding. Both pre- and post-situational interests were found to influence on conceptual understanding via attention. Attention had influences positively on deep learning strategy and negatively on surface learning strategy. There was a relatively small effect of state learning strategies on conceptual understanding.
