This study reviewed the literature on the self-distancing method for emotion regulation. Self-distancing refers to taking a step back in dealing with one's own experiences and interpreting them in a relatively objective manner. Studies have indicated that self-distancing affects cognitive and emotional processes, which are particularly beneficial in regulating negative emotions. Therefore, this study focused on organizing previous results to summarize their meaning, assess means of measurement, and analyze possible effects. Above all, the related concepts of an observer's rational perspective and self-reflection were presented to clarify the definition of self-distancing, followed by a discussion of its measurement. Based on this, the effects of self-distancing were introduced according to their emotional, cognitive, physiological, developmental, and behavioral aspects. However, despite repeated verification of the positive effects of self-distancing, there are several inconsistencies that require consideration. Finally, we suggested the study's academic and practical implications and recommended directions for further research.

This study conducted a survey to measure recognition distance between the materials which are located separately in a children's library targeting 200 elementary school lower grade students, higher grade students, and school parents(adults). And compared recognition distance between the elements of materials of individual visitor group with multidimensional scaling and K-mean group analysis. Multidimensional Scaling (MDS) is a technique for projecting the cognitive state in space by evaluating the similarity or attribute of the analysis target. Even though it is mainly used for market diagnosis in marketing, It can also be applied to present an ideal physical layout plan by analyzing the distance. As a result of analysis, the main discoveries are as follows. First, elementary school students cognize child, baby and computer materials should be adjacent as a same group. But recognition of adults(school parents) is reflected by differing from elementary school students vastly. They cognize that computer materials should be formed as a special group separated from child and baby's materials. Second, elementary school higher graders and adults(school parents) groups also want to separate their main reading materials from baby's book, therefore They both want to secure silent reading space separating from baby. Third, as a result to confirming how this recognition distance system of materials is reflected in a real children's library through three children's libraries in Y-gu, Incheon, there is no library with structure according perfectly with a recognition system of a particular class, but a recognition system of adults and elementary school students is partially reflected because baby, child and computer materials, and baby and child materials are commonly separated and placed. It is difficult to insist that a recognition system of a visitor group, especially a recognition system of children is absolute consideration conditions in material placement of a children's library. However, understanding cognition of the user groups can be an important evidentiary factors to offer differentiated service space according to visitors and effective placement of the elements of library resources.

This paper deals with the anaphoric usage of demonstratives when they refer to what are already mentioned in the context. We examine syntactic, semantic and pragmatic factors that contribute to the choice of demonstratives. As for anaphoric usage, English and Spanish show the even distribution between proximal and distal demonstratives with the meaning of their deictic counterparts. Korean and Russian, however, show the uneven distribution of the more prevalent form (unmarked on) and the lesser one (market one). This study aims at a typological explanation for the anaphoric usage of demonstratives through comparison and contrast with such factors as the distance to the antecedent, cognitive status, psychological distance and the center of attention.

Two primary objectives of this study were to determine important personal factors in performing cognitive distance mapping, and to understand how human's cognitive distance mapping capabilities were influenced by reference and subjects' locations using Global Positioning System (GPS). Undergraduate and graduate students at the University of Kansas, USA were interviewed and surveyed throughout the campus area giving them a paper-and-pencil test. Study results showed that females had more accurate cognitive mapping capability than males regardless of ethnic background and academic levels. Generally, subjects with longer affiliation with the university, higher ages and academic levels had less variability in their mapping accuracy. Subjects tended to more accurately map the target locations closer to the reference points than those located farther away, and subjects who were closer to a reference point performed their distance mapping better than those farther away. A correlation analysis reported that male subjects used reference-to-target and subject-to-reference distances more sensitively than females to estimate the locations of the targets. This result indicates that males might have used the reference point-based map scale more strenuously than females.

Drivers need lots of information when they drive on the highway, however it is necessary and important to be provided information which is appropriate formation. In order to offer the suitable information, adequate size, quantity, and frequency of provided information are required for the drivers. To evaluate propriety of the expressed message of VMS that provides real-time traffic conditions, first of all, the amount of message about legibility distance and viewing should be estimated. In this research, drivers' characteristics of VMS message design were also reviewed to enhance the efficiency of VMS. And legibility distance, the amount of viewing information, and ratio of viewing information were analyzed on the currently operating VMS. The results of this study proposed that the appropriate size, quantity, and frequency were concluded by the legibility and memory of message on the real driving conditions. Consequently, these design methods of VMS could be expected to improve the transmitting capability of highway information to drivers.

Driving maneuvers in car-following are affected not only by the factors related to road and traffic conditions, but also by factors related to drivers' cognition to them. This paper attempts to analyse drivers' car-following distance tests on road characteristics. Driving maneuvers are directly observed by video recorder sets in the vehicle. At the same time drivers are interviewed about their cognitive degree of car-following distance according to a given level of cognitive language. As a result, linguistical cognition of car-following distance is well fitted in with Weber-Fechner's law. This paper suggests a modeling method that takes into account the driver's cognition for acquiring traffic visible information on driving maneuver.

This study investigated the effects of delineation systems on drivers' maneuver and how the effectiveness of delineation system can be further improved according to the road geometry. The experiments were conducted to collect lateral placement data and detection distance data using GPS equipped vehicles. The main results are summarizedas follows. Firstly, installing the delineation facilities on the roads helps drivers to recognize road alignment. Secondly, the detection distance is longer for delineators than for raised pavement marker in tangent section, while there is no difference in curve section. The chevron show the longest detection distance in the curve section, while the raised pavement markers showed no distinctive performance in terms of detection distance and lateral placement. Therefore, we can recommend install delineators in the tangent sections and chevrons in curve sections, based on the analysis results of effects of delineation facilities.

인공건물의 평면특성에 대한 시각을 통한 인지를 청각으로 대체했을 경우의 인지능력을 측정하였다. 정상적으로 시각(visual)을 이용하겠으나, 시각 장애자의 경우는 청각(auditory) 또는 촉각(tactile) 또는 두가지 모두를 사용하게 된다. Psychophysical approach를 사용하여 모의평면에 대한 인지능력을 JND단위로 측정하였다. 청각적인 신호를 관찰자에게 제공하기 위해 전자장치(electronic ranging device)가 고안되었다. 이 장치는 목표물까지의 거리를 초음파의 이동시간으로 측정하여 음의세기(sound level)로 발생시켜 준다. 관찰자는 이 음의 세기를 듣고 거리를 추정하고 물표의 방향은 이 장비를 쥔 손의 방향, 즉, proprioceptive cue를 이용하게 된다. 세가지 task에 대한 실험은 평면의 slantness, 두 평면이 교차하는 모서리의 크기, 두 평면사이의 공간(aperture size)등에 대한 인지능력의 측정실험이다. 실험결과를 보면, 관찰자는 시각신호 대신에 청각신호를 사용할 수 있는 능력이 있는 것으로 나타났다. 세가지 task별 JND측정치는 slant angle 6도, 모서리의 concavity 10도, angular aperature size 3-5도로 나타났다. 이 결과는 정상인이 시각을 이용한 인지능력과 큰 차이가 없음을 보여주고 있다.
