안구의 운동은 시각 환경에서의 진행중인 정보처리와 관련된 지각적, 인지적 과정을 밀접히 반영하는 중요한 지표로서, 특히 공간 지각과의 상관은 비교적 명확히 확립되어 있다. 본 연구는 공간지각에 관여하는 안구운동의 특성을 파악하여, 공간지각을 반영하는 안구운동 지표를 개발한다는 목표 아래, 피험자가 느끼는 공간의 확장과 축소의 특성을 이중도약과제(double-step paraeigm)를 사용하여 관찰한 것이다. 이중도약과제는 도약(saccadic)안구운동의 오차를 유발시키는 실험기법으로, 두개의 시각자극을 하나씩 연속적으로 보여주되, 두번째 자극은 안구운동이 일어나는 도중에 제시하는 것으로서, 인위적으로 왜곡된 공간에 대한 피험자의 공간적응을 관찰하는데 사용되었다. 이 과제는 다시 자극의 이차도약 방향에 따라 축소감 조건과 확장감 조건으로 나뉘었고, 머리운동의 역할을 판별하기 위해 머리를 고정한 조건과 머리를 자유롭게한 조건으로 분류되었다. 그 결과 머리가 고정된 상태에서는 축소감 조건에 대한 적응이 확장감 조건에서보다 더 빨리 일어나고, 그 적응후의 시선이동의 변화량에서도 축소감 조건이 더 크게 나타났다. 또한 머리를 자유롭게 할 공간 지각의 정확성이 증가하며, 축소감과 확장감 경험속도의 차이가 약 49.2%까지 해소되었으나, 여전히 축소감의 경험이 더 잘 일어났다.

본 연구는 한글 어휘의 지각과정을 분석하여 한글이 표의와 표음의 이중성을 갖고 있다는 것을 밝히고자 하였다. 먼저 문자로 쓰여진 어휘들이 표음심도에 따라서 그 지각과정이 달라진다는 표음심도가설의 한계를 확인하고 다음에 어휘들의 지각과정에 표음심도와 독립적으로 표의강도가 영향을 미친다는 것을 검증하고자 했다. 실험 1은 칠종성어휘와 비칠종성어휘를 대비시킴으로써 표음심도를 조작하였지만 그 어휘들의 지각과정이 달라지지 않았으므로 표음심도가설의 한계가 드러났다. 실험 2는 의성-의태어와 일반어를 대비시킴으로써 표의강도를 조작하여 그 효과를 얻었다. 두 실험을 종합하면 어휘의 지각에 표의성과 표음성이 독립적으로 영향을 미치고 한글의 어휘는 표음적이면서 표의적이라는 것을 결론지을 수 있었다. 본 연구는 어휘의 지각을 바탕으로 표음이 아니면 표의라는 배타적 분류의 한계를 지적하고 표의와 표음의 이차원적 분류를 제안한다.

This study identified the relationship between perceived mother-grandmother conflicts and subjective well-being among multicultural children, and examined the double mediating model of acculturative stress and adjustment to school life on that relationship. Participants were 205 male and female adolescents living at J county in Gangwon-do. PROCESS Macro 3.5 Model 6 was used for analysis of a double mediating effect. Results revealed that perceived mother-grandmother conflicts was positively correlated with acculturative stress of multicultural children, and negatively correlated with adjustment to school life and subjective well-being. And, acculturative stress of multicultural children was negatively correlated with adjustment to school life and subjective well-being, whereas adjustment to school life was positively correlated with subjective well-being. This study found that acculturative stress and adjustment to school life were sequentially mediating perceived mother-grandmother conflicts and subjective well-being of multicultural children. These findings suggest that the perceived mother-grandmother conflicts might cause multicultural children to experience acculturative stress, and as a result, their subjective well-being level might be reduced due to their low adjustment to school life.

The primary goal of the present study was to examine the moderating effects of coping strategies, cultural identity, and bicultural self-efficacy on the relationship between perceived discrimination and depressive symptoms of Korean Canadian college students. Data were collected from 214 Korean Canadian college students studying in Canada through an online and offline survey. A direct effect of perceived discrimination on depressive symptoms and the moderating effects of coping strategies on the relationship between perceived discrimination and depressive symptoms were examined by using hierarchical regression analysis. And three-way interaction of perceived discrimination, coping strategies, and cultural identity, and perceived discrimination, coping strategies, and bicultural self-efficacy on depressive symptoms were examined. Results from a hierarchical regression indicated that perceived discrimination significantly predicted depressive symptoms and this finding is in line with previous studies. Second, reflective, suppressive, and reactive coping strategies did not moderate the relationship between perceived discrimination and depressive symptoms. Third, the three-way interaction effect of perceived discrimination, suppressive coping strategy, and heritage identity predicted the depressive symptoms. Low heritage identity, high level of perceived discrimination and the frequent use of suppressive coping strategy increased the level of depressive symptoms. Fourth, the three-way interaction effect of perceived discrimination, coping strategies, and bicultural self-efficacy did not predict the depressive symptoms. Limitations and applied implications of the results are discussed.

A psychological disturbance caused by letters in double image was termed as'letter sickness'.The effects of stimulus exposure time and letter familiarity on the letter sickness were measured to test a hypothesis that disturbances in eye movement and recognition stages is the cause of letter sickness.Letter sickness incteased significantly as stimulus exposure time lengthened from 50ms,100ms,to 3000ms.It was also significantly higher with familiar Hangul letters as compared with less familiar foreign letters and meaningless words as compared with meaningful words,respectively.These experimental findings imply that letter sickness is caused by the failure of adjusting eye movements to dismiss the double images.that the more familiar the letters.the more strongly the letter-identification process is commotted,resulting in the increased effect of disturbance from double image.and that the disturbance effect of double image is amplified when it is hard to extract the meaning from familiar letters.An experiment where subjects were made to learn Braille-like symbols consisting of 6 dots to test the hypothesis that the stronger the tendency to process the meaning of a symbol,the stronger becomes letter sickness due to double image,also showed that letter sickness significantly increased as a function of learning.

The present study examined how the psychological well-being of young adults was affected by the perceived parental rearing attitudes and how self-concept clarity and the perceptions of emerging adulthood mediated this causal relationship based on Arnett's the theory of emerging adulthood. We specially focused on affectionate or rejective types of perceived parental rearing attitudes and possibility or instability perceptions of emerging adulthood. We performed survey research with 358 university students from six universities located in Seoul, and other cities in South Korea and analyzed collected data using SPSS 25.0 and SPSS Macro. As a result, we found correlational relationships between psychological well-being of emerging adulthood and other variables. Also, we found the mediating effect of the self-concept clarity in the relationship between the psychological well-being and the perceived parental attitudes: affectionate, rejective. However, we only found the mediating effect of the perceived possibility perception of emerging adulthood was significant in the relationship between the psychological well-being and affectionate parental rearing attitudes. Finally, we found a sequential mediation effect that the self-concept clarity and then perceived instability perception of emerging adulthood affected in the relationship between psychological well-being and rejective parental rearing attitudes of emerging adulthood. Based on results, implications and suggestions for counseling service and psychological education for university students faced emerging adulthood were discussed.

There are many researches about effects of consumer innovativeness on the new product adoption behavior. However most of these studies regard this construct as one dimensional concept so that the extant studies suggest very ambiguous results about the relationship between consumer innovativeness and adoption behavior. This study subdivides the construct as cognitive innovativeness and sensory one and suggest these two types of consumer innovativeness affect on the risk perception of the potential adopter differently when the consumer adopt new product. In the empirical research through regression analysis and structure equation model with 217 samples, the study shows the consumer who have high level of cognitive innovativeness are more sensitive to functional risk of new products compared to one who have high level of sensory innovativeness. On the other side, sensory innovative consumer perceive social risk more when they adopt new products than cognitive innovator who have higher level of cognitive innovativeness. The result means there are dual paths on the relationship between consumer innovativeness and new products adoption behavior. Unlike the early studies, this study shows that there's dual path in relationship between the consumer's innovativeness and new product adoption. That is the consumer who have higher sensory innovativeness perceive the social risk of new products more sensitively than functional risk but the consumer who have cognitive innovativeness perceive functional risk more. So, new product adoption behavior would be different depending on the sensory or cognitive innovativeness.

This thesis revolves around dual sensory therapy techniques using perception arts group counseling program focused on Popcorn Brain phenomenon. The program emphasizes intrinsic motivations for changes by activating the brain's dual sensory such as a sense of smell, tactile sensation and vision to deal with brain issues caused by digital devices addiction. Perception arts group counseling program is based on voluntary satisfaction of relationship desires, which can lead to a sense of accomplishment and belonging. Expression methods using dual sensory were presented as an alternative to resolving digital devices addiction by blending cognitive-behavioral counseling technique and group art therapy technique. The blending method offers an environment that can maintain a change to a senseless and lackluster brian due to excessive uses of digital devices, the main cause of Popcorn Brain, by emphasizing "thoughts${\rightarrow}$emotions${\rightarrow}$behavior" with a structural expression approach. If perception arts group counseling program is established in more systematic fashion and used strategically to offer such environment, it may be used as a treatment for brain issues described above. In addition, the program can be used a basis for encouraging voluntary treatment to satisfy relationship desires.
