  • Perception refers to the process of acquiring all the information about the environment through various sensory organs such as the visual, auditory, tactile, and olfactory senses and integrating and interpreting the information transmitted to the brain. The ability to use these perceptions efficiently is called perceptual skill, and perceptual skill is an important factor for improving performance in the field of sports. As a result, many researchers have developed various perceptual training programs to maximize these perceptual skills while they have also progressed on attempting to verify their effects. The perceptual skill training introduced in this study is a training method that focuses on visual perception and is a training method that is applied in the United States and Europe. to improve sports performance. As a result of carrying out the perceptual skills training based on the kicker's important clue (the kicker's hip - the angle of the body and foot before kicking) to the goalkeeper in the situation of a soccer penalty kick improved the ability of predicting the direction of the ball while even in tennis, carrying out the perceptual skills training based on the server's important clue (position, ball, racket) improved the accuracy of the ability to predict in the direction of serve. Recently, there have been numerous research studies that were carried out on such perceptual skills training, but the number of studies conducted are insufficient, especially in Korea where research studies on perceptual training seem to be in a relatively neglected state. In addition, extensive studies need to be carried out to investigate whether the improvement of perceptual skills in the laboratory situation can be transitioned to an actual performance situation. Therefore, in order to elevate sports performance, researchers need to examine the perceptual training program's extent of necessity as well as the research direction regarding its effects.

  • 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 purpose of the present study was to investigate the relationship between spatial-erceptual ability and several aspects of driving-related situation awareness(in particular, recognition and prediction). Video clips of real driving were used in both recognition and prediction tasks, and the digit calculation task during driving the simulator was required as the integration task of recognition and prediction. The results showed that the subjects of higher spatial-perceptual ability performed better in recognition task, especially in terms of sensitivity measured in d'(as signal detection theory), prediction task, and digits calculation performance than those of lower spatial-perceptual ability.

  • 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.

  • The purpose of this study to know the effects of craft programmes on the visual perceptual development of the children with developmental disabilities. Sixty children were diagnosed with developmental disabilities. They divided into two groups that were the experimental group and control group. The children were subjected at K-Rehabilitation Center and C-child Care Center in Gyeong-Ju for 6 weeks from Feb to Apr (twice a seek, total 12 times) in 2011. The development programmes for the children disabilities are based on occupational therapy, physical therapy, and speech therapy. The intervention of experimental group included occupational therapy based on the craft programmes, physical therapy, and speech therapy. The one of control group included occupational therapy based on function, physical therapy, and speech therapy. The MVPT-3 and K-DTVP-2 were done before and after the therapy to compare visual perceptual development ability and to know the results of the test. Results were as follow: First, there were significant differences of MVPT-3 score before and after the therapy. Second, there were significant differences of K-DTVP-2 score before and after the therapy. The results mean the craft programmes had a positive effect on the visual perceptual development of the children with developmental disabilities.

  • 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.
