This paper is to provide an analysis of the aspectual nature of naked infinitives(NIs) of English perceptual reports. Higginbotham(1983) proposes that only ‘active’ or ‘transient’ verbs can be used as NIs of English perceptual reports, but ‘state’ verbs cannot. This is called “confinement to the active or transient”. But there will be one problem when NIs of English perceptual reports are negatives. This is why the meaning of negative NIs of English perceptual reports may be static, which isn't in line with “confinement to the active or transient”. There are similar problems with ‘state’ NIs of English perceptual reports. In this paper some of these problems can be solved with the “Event Structure” of Pustejovsky(1991). According to Pustejovsky(1991), ‘process’ and ‘transition’ verbs have sub-eventual individuation units, but state verbs have no such units. It is the units that make it possible for ‘process’ and ‘transition’ to be perceived. As a result ‘process’ and ‘transition’ verbs are suitable for NIs of English perceptual reports. Nevertheless, there are still some problems unsolved. Moreover some state verbs are grammatically used as NIs of English perceptual reports. This paper proposes that these state verbs have “potentiality of transition”, and the potentiality comes from only the combination of the two parts of the complement - the subject and the naked infinitive. And the potentiality causes the “Event Structure” of Pustejovsky(1991) to be modified. And this modification makes it possible for us to explain aspect of NIs of English Perceptual Reports. It is concluded with some implication for Korean learners of English as a Foreign Language.

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.

선택적 정보처리에 관한 지각적 부담 가설과 희석 가설을 비교하기 위해 세 개의 실험을 실시하였다. 지각적 부담 가설은 행동 목표에 부합하는 과제의 지각적 부담이 적을수록 불필요한 정보가 더 깊이 처리될 수 있다고 보는 반면, 희석 가설은 지각적 부담에 관계없이 제한된 주의 자원에 대한 경쟁에 의해 정보 선택 여부가 결정된다고 본다. 두 가설을 비교하기 위하여 표적 탐색의 지각적 부담이 방해자극의 반응 간섭에 미치는 영향을 측정하였다. 실험 1과 2에서는 탐색 배열을 구성하는 비표적자극의 개수와 색깔을 각각 조절하여 시각탐색의 지각적 부담을 조작하였다. 그 결과 방해자극의 간섭은 지각적 부담에 상관없이 비표적자극이 많을수록 감소하였다. 실험 3에서는 비표적자극의 역할을 규명하기 위해 비표적자극과 방해자극의 지각적 범주를 같거나 다르게 제시하였다. 그 결과 지각적 범주가 같을 때에만 방해자극의 간섭이 감소하였다. 전반적으로 본 연구의 결과는 지각적 부담 가설보다는 희석 가설과 일치하며, 더 나아가 시각 정보의 선택이 지각적 범주 별로 특화된 주의 자원의 제약을 받는다는 증거를 제공한다.

The acoustic quality of a vowel is known to be mostly determined by the frequencies of the first formant(Fl) and the second formant(F2). The perceptual(or psychological) dimensions of vowel perception were examined in this study. Also the relationships among perceptual dimensions, acoustical dimensions(Fl & F2), and articulatory gestures of vowel were discussed. Using multi-dimensional scaling(MDS) technique, the experiment was performed in order to identify the perceptual dimensions of the perception of Korean vowel. In the experiment 8 Seoul standard speakers performed the similarity rating task of 10 synthesized Korean vowels. Two-dimensional MDS solution based. on the similarity rating scores was obtained. The results showed that two perceptual dimensions, D1 and D2 were correlated strongly with F2 and F1(r = -.895 and .878 respectively), and were so interpreted as 'vowel advancement' and 'vowel height' respectively. The relationship between the perceptual dimensions of vowel and the articulatory positions of tongue suggested that perception may be directly linked to production. Further research problems were discussed in the .final section.

The present study was carried out for the period from July 14 through September 13, 1975 by means of questionnaire distributed to 300 nursing students whose extent of satisfaction is known to be relatively low compared with other students of the different course of study by applying the perceptual orientation scale based on the principle defining that the effectiveness in maintaining helpful relation with others in human society depends upon the perception possessed by individuals, The present study was intended to investigate the effectiveness of nursing profession for nursing students of the 4- year system and 3- year system nursing school and relationship between perceptual orientation and clinical achievements, thereby, attempting more efficient application of the perceptual orientation scale. The results obtained are summarized as follows : 1. There was observed no significant difference in perceptual orientation between the nursing students of the 4- year system and 3- year system nursing schools. 2. There was observed significant correlation between the perceptual orientation and clinical achievements of the nursing students. 3. In the comparison of the perceptual orientation Point and mean value by school significant difference was observed between schools other than B and C schools of the 4 - year system. 4. Marked correlation was observed between the perceptual orientation and clinical achievements of the students of 4 - year system nursing courses. 5. Low correlation was observed between the perceptual orientation and clinical achievements of the students of the 3- year system nursing school.

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.

In this paper, we describe a system for controlling the perceptual processes of two cooperative mobile robots that addresses the issue of enhancing perceptual awareness. We define awareness here as knowing the location of other robots in the environment. The proposed system benefits from a formalism called perceptual anchoring. Here, perceptual anchoring enhances the awareness of the system by employing an anchor-based active gaze control strategy or active perceptual anchoring to control the perceptual effort according to what is important at a given time. By anchoring we extend the notion of awareness as knowing what the symbols in the control module represent to by connecting them to the objects or features in the environment. We demonstrate the present system through a simulation of two nonholonomic mobile robots performing a cooperative transportation by carrying a cargo to a target location where there are two other robots moving about. The system is able to efficiently focus the perceptual effort and thus able to safely carry the cargo to the target position.

This study is designed to reveal the relationship of Army Nurses′ effectiveness to their perceptual orientation. Studies on nurses are very few despite of highly professional duties which deal with human lives. Effectiveness of nurses could be seen from both within and without. At present study, however, the researcher tried to work on the point of view of perceptual psychology. The study was designed !o fined the relationship of "Perceptual Orientation Scale"to their ratings training courses and experiences. The subjects are limited to nurses serving in the Army of the Republic of Korea. Many researches on nurses, such as Young Bok Lee(1970), Sook Ja Yoo(1971) Young Sook Hong (1970), Ik Do Choi (1966), are dealt with their attitude, morale, how to see their profession, adjustability and college lives, tut no one ever studied their subjective perceptual orientation. Method "Perceptual Orientation Scale"(Chunghoon Choy, 1971) was administered to 315 Army Nurses during the period of June to November 1971, and the relationship with their ratings by their supervising officers, training courses and their experiences were tested. All the relationship were calculated by the method of Chi-Squares. Result 1) There is no significant relationship between "Perceptual Orientation Scale" and their ratings. 2) There is no significant relationship between "Perceptual Orientation Scale" and their training courses. 3) There is no significant relationship between "Perceptual Orientation Scale" and their experiences. Conclusion As far as calculated result are concerned the research could not fined any Significant relationship. Therefore we can conclude that "Perceptual Orientation Scale"of the nurses has nothing to do with nurses effectiveness. It means the Army Nurses rating method has to be modified at once. Also we have to continue to fined mole significant effectiveness criteria and other researches be encouraged.
