지각이란 다양한 감각기관을 통하여 시각, 청각, 촉각, 후각 등 주위 환경에 대한 정보를 습득하는 과정으로 뇌에 전달된 정보를 통합하고 해석하는 것을 의미한다. 이러한 지각된 정보를 바탕으로 상황에 적합한 정보를 효율적으로 사용하는 능력을 지각기술(perceptual skill)이라 하며, 스포츠에서 지각기술은 경기력 향상을 위한 중요한 요소로 작용한다. 따라서 많은 연구자들은 지각기술을 극대화하기 위하여 다양한 방법의 지각기술훈련 프로그램을 개발하고, 그 효과를 검증하려는 시도들이 진행되고 있다. 본 연구에서 소개하고 있는 지각기술훈련은 시지각에 중점을 둔 훈련 방법으로 미국이나 유럽에서 스포츠 경기력 향상을 위해 적용하는 훈련프로그램이다. 축구 페널티킥 상황에서 골키퍼에게 키커의 중요 단서(키커의 엉덩이-몸통, 발의 각도)를 바탕으로 지각기술훈련을 실시한 결과, 볼의 방향 예측 능력이 향상되었고, 테니스에서도 서버의 중요 단서(자세, 공, 라켓)에 대한 지각기술훈련을 실시한 결과, 서브 방향에 대한 예측능력이 향상되었다. 최근 지각기술훈련에 대한 연구가 활발하게 진행되고 있지만 아직까지는 연구의 수가 많지 않으며, 대부분이 실험실 상황에서의 연구로 실제 경기 상황에서의 활용에 대한 연구가 부족한 실정이다. 따라서 연구자들은 스포츠 경기력 향상을 위하여 지각기술훈련의 필요성을 검토하고, 그 효과에 대한 연구 방향을 포괄적으로 검토해 보는 시도가 필요하다.

The main purpose of this study was to explore the development of knowledge about the appearance-reality distinction and the perspective-taking ability and to examine its relation. The subjects were 104 children, 13 boys and 13 girls each at the age of 3, 4, 5, and 6. The performance of four age groups were compared on illusion appearance-reality, color appearance-reality, perceptual perspective-taking, and cognitive perspective-taking tasks. The data were collected by individual testing and analyzed by the two-way ANOVA with repeated measures, one-way ANOVA and Pearson Correlation Coefficients. The major results were as follows. 1. In children's understanding of the appearance-reality distinction, significant differences were found between 3-year-olds and 4-year-olds, and 5-year-olds and 6-year-olds. While between 4-year-olds and 5-year-olds showed no such differences. Besides, gender did not affect the children's understanding of the appearance-reality distinction. 2. There was significant difference in performance according to the type of tasks. That is 3-year-olds perform better illusion appearance-reality distintion than color appearance- reality distintion, while 4, 5, 6 year old children's performance of color appearance-reality and illusion appearance-reality distinction showed no difference. 3. In children's ability of perceptual perspective-taking, significant difference was found between 3, 4, 5-year-olds and 6-year-old children. And in ability of cognitive and perspective-taking, significant difference was found between 3, 4-year-olds and 6-year-old children. Besides, gender did not affect the children's perceptual and cognitive perspective-taking. 4. The color appearance-reality distinction and perceptual perspective-taking showed significant correlation. That is, the children of high grade for perceptual perspective-taking were better understanding of color appearance-reality distinction.

The goal of the current study is to investigate whether L2 learners' perceptual ability regarding epenthetic vowels is interconnected with other aspects of speech recognition, such as lexical stress, sentence focus, and vowel recognition. Twenty-five Korean L2 learners of English participated in perception experiments assessing vowel epenthesis oddity, lexical stress oddity, sentence focus oddity, and vowel identification. Results indicate that accuracy on the vowel epenthesis oddity test is influenced by both lexical stress and sentence focus, suggesting that perceptual ability regarding epenthetic vowels is influenced by the acquisition of L2 rhythmic structure at both word and sentence levels. Additionally, this study identifies a proficiency effect on vowel epenthesis recognition, implying that the influence of L1 phonotactics diminishes as L2 proficiency increases. Taken together, this study illustrates the interaction between perceptual abilities in vowel epenthesis and prosodic stress in the field of L2 speech perception.

Objective: The purpose of this study was to determine the force of lower extremities, the change in walking ability on the ground by applying a walking training program based on perceptual learning to improve gait capacity of chronic stroke patients. Method: This study included Twenty-four patients with chronic stroke. Using a perceptual-based gait training, the experimental group trained twice a day for 30 minutes each time, 5 times a week, for a total of 8 weeks. The control group underwent ground gait training that excluded the element of a perceptual training for 30 minutes, 5 times a week for 8 weeks. Results: In the two groups, the maximum forefoot pressure after intervention was significantly different in both the LEPGT and GGT (p<0.05). The maximum midfoot pressure was significantly different in LEPGT (p<0.05). There was a significant difference in the maximum heel pressure after intervention between the two groups (p<0.05). As a result of comparing the change in step length and stride length after intervention in the two groups, there was a significant difference between the two groups (p<0.05). Conclusion: Both gait training programs was found that gait training based on perceptual learning and ground gait training were the training for improving the functional gait of stroke patient. Perceptual learning gait training utilizing intensive perceptual awareness was the training for improving gait capacity within the period than ground gait training.

This study is aimed to compare the effect of visuo-perceptual biofeedback sitting balance training and conventional sitting balance training using Balance Master on stroke patients with that of program in order to analyze the effect it has on dynamic postural balance. The subjects are twenty-four stroke patients who are receiving physical therapy in Ilsan Paik Hospital and can maintain sitting posture by themselves. These patients were divided to control group and experimental group randomly. In order to compare to control and experimental group before and after the balance training, they were tested with Mann-Whitney U test and in order to compared the changes before and after the balance training, they were tested with Wilcoxon signed-ranks test. The results are as follows: we measured the ability of dynamic posture balance control with limit of stability(LOS) test and rhythmic weight shift test. There was an increasing improvement in the ability of dynamic posture balance control of the experimental group that had visuo-perceptual biofeedback sitting balance control training using the Balance Master(p<0.05, p<0.01). According to the results from above, compared to conventional sitting balance training programs, visuo-perceptual biofeedback sitting balance control training using the Balance Master is considered to be a more valuable therapy in balance control improvement and physical function improvement. It is considered that if the weak points are made up, the training with Balance Master will give help to stroke patients and to patients with balance control disabilities and will further more contribute to successful rehabilitation therapy.

This thesis intends to make a study on the effectiveness of Nursing Professors through perceptual psychological approach. Purpose of the Study Researches have been made relating teacher′s effectiveness measurement. However, they share a common defect that they have been done on the basis of superficial aspects of the problems aspects that can bi measured by general objective survey only, but this study is designed "to understand his behavior in terms of a human behaving and of a self as an instrument"-principle, based upon the Perceptual Psychology which puts more stress on the inner perception than on the external one. Method of the Study This thesis is based chiefly on the two sources : "Perceptual Orientation Scale"(Chunghoon Choy, 1971) which has been standardized on the basis of perceptual psychology and the question acres made by the researcher of this thesis and given to the 34 Nursing Professors in seoul and other country. Result of the Study The method of data operation by Pearson "r" asserts that there were distinct deep relation Between Perceptual orientation and fellow′s estimate, while a little relation among the estimate of a-administration, educational backgrounds and occupations but no relations the status of experiences. It can be concluded that the estimates between fellows working at "the same fields" have kept deep relations together on perceptual orientation which resulted from finding out a useful method to measure occupational effectiveness according to the perceptual field. Conclusion of the Study The personnel administration has been managed according to external flatus and not positive operation: on the other hand, this study holds, It shall be operated in accordance with the estimates by fellow, the "Preceptual Orientation Scale" for more positive ability. The study requires the following researches on the devoted professional occupations, such as medical doctors, teachers, nurses, etc. for the purpose of increasing their occupational effectiveness more scientifically.

In order to understand the various groups' perceptual pattern in both VCV trochee and iambus, this study examined the identification correctness and cue robustness for the unit intervals in light of background language, age, and English listening ability. The 4 groups of Native Speakers of English, Korean College Students of High Listening Achievement, Korean College Students of Low Listening Achievement, and Korean Elementary Students took part in the experiments. Tokens of $/d{\ae}per,\;d{\ae}per,\;d{\ae}per,\;d{\ae}per,\;d{\ae}per,\;d{\ae}per$ in trochee and of $/{\eth}{\partial}\;p{\ae}d,\;{\eth}{\partial}\;b{\ae}d,\;{\eth}{\partial}\;t{\ae}d,\;{\eth}{\partial}\;d{\ae}d,\;{\eth}{\partial}\;k{\ae}d,\;{\eth}{\partial}\;g{\ae}d/$ in iambus were extracted and modified into experimental signals composed of two digits(voiced-1, voiceless-0) by following the temporal intervals, in which the signals consisted of preceding vowel, closure, VOT, and post-vowel. In the first experiment of identification correctness in VCV iambus environment, all groups showed almost 100% correctness rate, while in trochee environment all groups were different(native speaker 87%, college high 74%, college low 70%, elementary 65%). In the second experiment of cue robustness, all groups showed the similar perceptual pattern in both environments. There was the order of robustness cues in VCV trochee: pre-vowel ${\gg}$ closure ${\gg}$ VOT ${\gg}$ post-vowel, while the order in VCV iambus: VOT ${\gg}$ post-vowel ${\gg}$ closure ${\gg}$ pre-vowel. In some condition, however, we found moderately different perceptual pattern depending on language, age and listening level.
