  • The interface of computer software has to promote human-computer interaction. The one quality of interface to promote HCI should be evaluted with regard to user's information processing. The usability of interface is one of the main components of it's quality, and it is straightforwardly concerned with learnability, especially when users want to use a software at the first stage. In this paper, word processors, wide spreadly used in OA environments is studied in respect to menu structure on the interface. An cognitive menu structure is suggested by user's conceptual network of the main functions of word processor. Two word processors is selected to compare with the cognitive menu structure and to evalute learnabilities by teaming model.

  • One of the characteristics of the neurons that distinguishes them from other cells is their complex and polarized structure consisting of dendrites, cell body, and axon. The complexity and diversity of dendrites are particularly well recognized, and accumulating evidences suggest that the alterations in the dendrite structure are associated with many neurodegenerative diseases. Given the importance of the proper dendritic structures for neuronal functions, the dendrite pathology appears to have crucial contribution to the pathogenesis of neurodegenerative diseases. Nonetheless, the cellular and molecular basis of dendritic changes in the neurodegenerative diseases remains largely elusive. Previous studies in normal condition have revealed that several cellular components, such as local cytoskeletal structures and organelles located locally in dendrites, play crucial roles in dendrite growth. By reviewing what has been unveiled to date regarding dendrite growth in terms of these local cellular components, we aim to provide an insight to categorize the potential cellular basis that can be applied to the dendrite pathology manifested in many neurodegenerative diseases.

  • This paper reviewed models to explain memory and neuropsychological tests to assess memory. Memory was explained in cognitive and neuroanatomical perspectives, Cognitive model describes memory as structure and process. In structure model, memory is divided into three systems: sensory memory, short-term memory(working memory), and long-term memory. In process model, there are broadly three categories of memory process: encoding, storage, and retrieval. Memory process work in memory structure. There are two prominent models of the neuroanatomy of memory, derived from the work of Mishkin and Appenzeller and that of Squire and Zola-Morgan. These two models are the most useful for the clinician in part because they take into account the connections between the limbic and frontal cortical regions. The major difference between the two models concerns the role of the amygdala in memory processess. Mishkin and his colleagues believe that the amygdala plays a significant role while Squire and his colleagues do not. The most popular and widely used tests of memory ability such as WMS-R, AVLT, CVLT, HVLT. RBMT, CFT, and BVRT-R, were reviewed.

  • It seems reasonable to assume that the individualized learning means more than simple teaching-learning method, so the instructional method has attracted a fair amount of attention not only in classroom, but also in the field of a adult education, cooperate education, and so on. In order to have an effect on individualized learning, we need to analyze and measure the learner's characteristic. However it is difficult to represent in quantified form because the conception and category of learner's characteristic is various and extensive. Therefore, in this paper, we propose a quantification method of learner's characteristic, which is limited to learner's cognitive structure and style, and is represented in the light of connectionism, verify the validity. The learner's cognitive structure in this paper was represented, which simplified the learner's cognitive structure. Additionally, the cognitive style in this paper was limited to inertia of knowledge for learner's cognition.

  • This research is that it could use a theory from a .cognitive science, making a hypothesis to explain the thingking steps of designing, adapting the problem solving of the design from knowledge of a cognitive science, to meet the possiblity which it can be developed the new way of the thinking. Design is a field where it needs a complexity with hi-brain activities. And cognitive science is a science which it study human brain activities. However, it is also quite possible to bo adaped over all design by linking with design and cognitive science. I explaned the ideation of the thinking steps on this study by the knowledge of cognitive science, to observe to be possible. I found out the new ways of possibilities from design thinking process. It is a result that I've been interpretated the design process and the thinking process out of the theory of knowledge structure.

  • In this paper, we first exam the relation between Piaget's theory of cognitive development and cognitive constructivism. With it's outcome We find three principles of constructivist teaching-learning methods for primary mathematics These are as follows 1) active learning based on self-regulatory process 2) empirical learning by self initiated activities 3) individual learning derived from present cognitive structure and fits of new experiences. Finally we introduce several examples for classroom practice applied the above principles in primary mathematics.

  • This study was contrived Hierarchical Information Search (HIS) model. HIS model is based on a “cognitive process” in which model, comprising basic human information processing mechanize and information interaction. Its process include 3 semantic cognitive processes: Schema-Association LTM, Form Domain, and Alternative Selection. Design methodology consists to elicitate memory, thinking and cognitive response variables. In case study, menu structure of mobile phone was applied. In result, a correlation between predictive error rate and real error rate was .892. and a correlation between selective and real reaction time was .697. This present to suggest a model of how the methodology could be applied to real system design effectively when this was used. HIS model could become one of the most important factors for success of product design. In the perspective, the systemic methodology would contribute to design a quantitative and predictive system.

  • This study analyzed the process of information service and its factors in the cognitive viewpoint. And developed a conceptual model to help in developing future information systems and services. The results of this study were summarized as follows : 1) The paradigm of information user study is changing from the system-centered to the user-centered one. 2) The researchers describe the user's internal cognitive process as the starting point of the information service. 3) The user's personal cognitive process influence the process of the information service over. And the focus is a microscopic one including the factors of the perception and recognition of the stimulus, remembering and searching information, reasoning the rules, recognition of the patterns, formalization of the concepts, etc. 4) The information librarian performs the role as a knowledge/ information system interface, and his knowledge structure reflects the organization of that knowledge/information system. 5) The information librarians can perform their role as information specialists actively and offensively. And the performance of the librarians can be measured on the scales of the su n.0, pplying capability of relevant information and the client satisfaction.

  • This article examines how individual differences on the need for cognitive closure and demographics influence consumer perception and the usage of consumer reviews in online shopping. Data were randomly collected from 2,381 U.S. online consumer review users through an online survey. The findings from multiple regression analyses revealed the different effects of the need for cognitive closure dimensions (i.e., preference for order and structure, preference for predictability, discomfort with ambiguity, closed-mindedness, and decisiveness) and demographic characteristics on consumer attitudes, perceived online review influence, benefits, persuasiveness, and review usage behavior. Finally, practical implications and prospects for future research are discussed.

  • Child's temperament, cognitive ability, social competence, mother's affective child rearing and positive expression, father's positive expression, and teacher's positive expression were the variables investigated in relation to the structure of children's emotional competence (EC). Subjects were 20 teachers and 236 five-year-old children and their parents. Data were analyzed by LISREL (Linear Structural Relations), a statistical program for structural equation modeling. Results showed that boys' social competence and mother's affective rearing behavior directly influenced the EC of boys; boys temperament and cognitive ability, and positive expressions of their teachers indirectly influenced the EC of boys. Girls' temperament and social competence directly influenced the EC of girls; their cognitive ability, mother's affective child rearing behavior, and positive expressions of mothers and fathers indirectly influenced the EC of girls.
