The distinction between short-term store (STS) and long-term store (LTS) has been made in the perspective of information processing. Memory system theorists have argued that memory could be conceived as multiple memory systems beyond the concept of a single LTS. Popular memory system models are Schacter & Tulving (994)'s multiple memory systems and Squire (987)'s the taxonomy of long-term memory. Those m models agree that amnesic patients have intact STS but impaired LTS and have preserved implicit memory. However. there is a debate about the nature of the long-term memory impairment. One model considers amnesic deficit as a selective episodic memory impairment. whereas the other sees the deficits as both episodic and semantic memory impairment. At present, it remains unclear that episodic memory should be distinguished from semantic memory in terms of retrieval operation. The distinction between declarative memory and nondeclarative memory would be the alternative way to reflect explicit memory and implicit memory. The research focused on the function of frontal lobe might give clues to the debate about the nature of LTS.

Since last several decades, iconic memory has been accepted theoretically valid for its role of the first storage mechanism in visual memory process. However, there have been relatively less interests in iconic memory among researchers than their interests in visual short- and long-term memory. Such little interests seem to arise from a lack of detailed understandings of theories and methodologies about iconic memory and visual persistence. This study aimed to achieve the understandings by reviewing theories and empirical studies of iconic memory and visual persistence. The study further discussed future direction of iconic memory research according to the essential aspects of phenomenological and ecological criticisms against the validity of iconic memory.

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.

In archival discourse, social memory has been discussed for some time. Despite this, however, theoretical studies have not been prolific at all in the Korean archival community. Many Western scholars have argued that archivists should consider memory rather than records for archival preservation because the inclusiveness of the former will fill the gaps in the latter. Social memory that is shared and transmitted across generations in society would include the stories of marginalized groups of people who are often neglected in official documents. Archivists can reconstruct the diverse narratives of a variety of social groups based on social memory, and this would be their social responsibility. In this sense, it is archivists who exercise power regarding how history will be written in the future because they determine what would be preserved in archives: mainstream culture with official records or a broader spectrum of diverse stories of people in society. From this perspective, this paper intends to understand how memory is discussed in archival discourse and to review how archives and history are associated with memory in theories and practices.

A new three-dimensional model for predicting the relationship between the prestrain of the composite and the amount of phase transformation of shape memory alloy inducing shape memory effect has been proposed by using Eshelby's equivalent inclusion method with Mori-Tanaka's mean field theory. The model composite is aluminum matrix reinforced with short TiNi fiber shape memory alloy, where the matrix is work-hardening material of power-law type. The analytical results predicted by the current model show that most of the prestrain is induced by the plastic deformation of the matrix, except the small prestrain region. The strengthening mechanism of the composite by the shape memory effect should be explained by excluding its increase of yield stress due to the work-hardening effect of the matrix.

The role of memory is viewed as central to developing and maintaining flight situation awareness (SA). The present research examines constituent memory processes that underlie flight SA sensitivity as a function of pilot expertise. In Experiment 1, pilot memory for different forms (spatial or verbal) of cockpit situational information was tested immediately after presentation of the information (immediate recall) or after 30-s delay filled with an intervening task (delayed recall). In Experiment 2, pilot SA sensitivity was examined and correlated with memory measures obtained in Experiment 1. Results suggest that an expertise effect occurs in delayed recall but not in immediate recall and that memory representation of situational information required to develop high levels of SA sensitivity varies as a function of expertise. Theoretical accounts of results are discussed in the context of psychological theories of expertise.

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.

This study was designed to examine the influence of task appropriate processing on prospective memory(PM). The TAP was manipulated with list type within study phase and association category type among PM target words. Associated word lists used for ongoing task were consisted of semantically associated lists and orthographically associated lists. Target words for PM task were consisted of city names or words for ending with the letter of '도'. According to the TAP view, PM performance would be better in the condition of task appropriate processing rather than in the condition of task inappropriate processing. Total fifty students volunteered for two experiments for the present study. The main finding was that PM performance was influenced by the task appropriate processing with ongoing task. In other words, PM performance was facilitated when association type between ongoing list and PM target word was same. Second, ongoing task performance was also influenced by task appropriated processing. These results were discussed in task appropriated processing theory and previous studies.

한 시계열의 자기상관계수의 절대값을 시차를 무한대로 접근시켜 가면서 각 시차에 대하여 구하고 이 절대값을 모두 더한 값이 무한일 때 이 시계열은 장기기억을 가진다. 이로 인하여 장기기억 모수를 추정하는데에는 자기상관을 기본으로 한다. 표본의 자기상관과 이론적 자기상관 사이의 거리를 최소하여 추정통계량을 유도하고 있는 것이 일반적이다. 이 경우에는 정상적 과정에 한하여 적용이 가능하다. 시계열은 어느 시계열이던지 간에 이 시계열에 적합한 모형이 존재할 것이고 이 모형을 시계열에 적용하면 잔차 시계열을 얻을 수 있다. 원래 시계열의 이론적 상관 대신 원래 시계열의 잔차 시계열의 자기상관과 표본의 자기상관 사이의 거리를 최소하여 추정통계량을 얻으면 통계량의 계산이 편하고 이 추정량은 정상적 시계열과 비정상적 시계열에 다같이 적용할 수 있다. 본 논문에서는 잔차의 자기상관을 이용하여 자기회귀 분수적분 이동평균 과정의 모수 추정량을 도출한다. 그리고 이 추정 통계량에 입각하여 주가의 형성과정을 살펴보고 장기기억이 옵션가격과 포트폴리오 구성에 미치는 영향을 밝힌다.
