The study was designed to investigate implicit and explicit memory for words with processing theory.From experiment 1 to experiment 3,in a study phase,subjects first viewed stimulus words and were required to rate likeness of words of semantic processing task and to count lines of words of perceptual processing task.In a test phase,subjects were tested by implicit word completion task and explicit cued recall task.In experiment 1,levels of processing (LOP)effects were examined.Lop effects were obtained on the explicit memory tasks but not on the implicit memory tasks.In experiment 2,repertition of perceptual processing task influenced onlu implicit memory task.In experiment 3,bepertiotion of semantic processing task affected both implicit memory task and explicit memory task.These findings suggest that repetition effect of stimulus words are explanied better in dual process theory than transfer-appropriate processing theory.

The study was designed to investigate implicit and explicit memory effec representations of bilinguals. Hierarchical model of bilingual information processing word naming and translation tasks in the context of semantically categorized or rar Experiments 1 and 2, bilinguals first viewed stimulus words and performed naming or tr then implicit and explicit memory tasks. In experiment I, word recognition times(exp were significantly faster for semantic category condition than random category condi naming task and lexical decision taskOmplicit memory task)showed no difference in e experiment 2, naming task and exlicit memory task showed categorization effect but fOWE a and implcit memory task showed no categorization effect. These findings support the which posits that memory representations of bilinguals are composed of two independer a and one common conceptual store.

Recebt neuropsychological studies on neurobiological bases of learning and memory in humans are reviewed. At present, cognitive psychologists belive that memory is not a unitary system. But copmosed of several independent subsystems. Adoption this perspective,this paper summarized findings regarding what kinds of memory discorders result from lesions of which brain areas and which brain areas are activated by what kind of learning/memory tasks. Short-term memory seems to involve widespread areas around the boundaries among the parietal,occipital,and temporal lobes,depending on the type of the type of the tasks and the way of presentation of the stimuli. Implicit memory,a subsystem of long-term memory,is not a unitary system itself. Thus,brain areas involved in implicit memory tasks used. It is well-known that medial temporal lobe is necessary for formation(i,e.,consolidation)of explicit memory,another subsystem of long-term memory. Storage and/or retrieval of episodic and semantic memory involve temporal neocortex. Perfromtal cortex seemas to be involved in several aspects of memory such as short term memory and retrieval of espisodic and semantic memory. Finally, a popular view on the locus of long-term memory storage is described.

Four experiments were conducted to examine whether maintaining the same conceptual context across study and test would affect performance on a perceptual implicit memory task. The sense-specific theory of priming (Lewandowsky et al., 1989) predicts greater priming from a match in conceptual context across study and test compared with a condition in which the conceptual context is mismatched, whereas the transfer-appropriate-processing view (e.g., Blaxton, 1989) predicts no difference. In experiment 1 and 2, little or no effect of varying context was observed on a implicit task. In experiment 3 and 4, a process-dissociation procedure (proposed by Jacoby, 1991) was used to separate automatic influences from consciously controlled influence in implicit memory, which was measured by Korean word completion task. The results showed that conceptual context effect was observed in consciously controlled parts of implicit memory. These results suggest that only consciously controlled processing parts of implicit memory is sensitive to conceptual context.

To do this, study of human memory and theoretical approach on form in general is carried out to compare the types of memories and the stage of perceive theoretically to discover the relationship between psychological perceive and form. In the second please, scenario of form recognition in cultural aspect is studied through various written records to obtain unbiased critics on what a person can feel from a form through various analysis and experiment. Examples will be given on products designed on the basis of correlation with form through analysis. Through this procedure, elements of reactions on implicit and explicit is derived (Data obtained from experiments on computers and inquiries are used) Analyzed elements are than divided into, general knowledge, memories of reality and subconsciousness memories and basic mental image and user mental image and mental image of form of each products are analyzed. In the third phase, the way of adapting of the elements obtained from the analysis of implicit and explicit reaction to the field of design is predicted. Together with this, future theme this the study will be suggested. Confusions obtained from this study can be listed as below.

Patients with panic disoder (PD) show recollection of their first panic attack, which resembles a trauma that is perceived as an unexpected frightening and subjectively life-threatening event. Information-processing models suggest that anxiety disorders may be characterized by a memory bias for threat-related information. This paper reviews the previous researches that investigated the implicit and/or explicit biases in patients with panic disorder. Among the 17 studies, which addressed the explicit memory bias in PD patients, 11 (64.7%) were found to be explicit memory bias in PD patients. In regards to the implicit memory bias, 4 out of 9 studies (44.4%) were found to support the memory bias. The result shows that evidence of explicit memory bias in PD patients was supported by a number of previous researches. However, evidence of implicit memory bias seems less robust, thus, needs further research for replication. Also, development of new paradigms and applications of various methods will be needed in further researches on memory bias in PD patients.

A Korean standardized set of pictures has been called for as more and more studies utilized picture stimuli among memory and representation research. This article presents a Korean standardized set of pictures for studies probing the cognitive mechanisms that underlie picture and word processing or studies that simply utilize pictures stimuli. This norm provides 213 pictures, data on several variables such as name agreement, appropriateness of pictures. and familiarity. Previous data on such variables as frequency. category. and frequency within a category have been integrated 1 into this norm. Limitation, usage. and application of this set are discussed in terms of 1 implicit and explicit memory, and those variables mentioned previously.

As the proportion of old people in contemporary societies steadily increases, the influence on cognitive rehabilitation strategy of the memory deficit associated with normal and pathological aging grows greater as well. This paper reviewed the current memory rehabilitation techniques for older adults. In the first part of this article, human memory systems as a framework for understanding memory aging were considered. In the second part, research findings concerning memory performance in normal aging and Alzheimer's disease were reviewed. Finally, recent evidence for the kinds of memory rehabilitation procedures with proven efficacy were offered. The existent memory rehabilitation technique have focused on prompt of residual explicit memory, use of preserved implicit memory, utilization of memory external memory aids. A suggestion of memory training based on brain plasticity as a novel approach is offered.

This study was conducted to examine whether conceptual representational system was implicitly accessed while processing semantically similar but perceptually dissimilar pictures either conceptually or perceptually, The results indicated that the priming effects for the semantically similar picture pairs were found in conceptually driven processing but the effect was not found in data-driven processing. In addition. the semantic priming effect was found with 24 hour delay between the stimuli, The comparison of the recognition ratio and priming effects indicated that the priming effect was largely affected by semantically similar pictures. but recognition was relatively u unaffected, The results suggest that both Perceptual Representational System (PRS) and Conceptual Representational System (CRS) be involved during conceptually driven processing, but both PRS and CRS function independently during explicit recognition.
