People observe a lot of events in our environment and we do not have any difficulty to perceive events including speech perception. Like perception of biological motion, two main theorists have debated on speech perception. The purpose of this review article is to briefly describe speech perception and compare these two theories of speech perception. Motor theorists claim that speech perception is special to human because we both produce and perceive articulatory events that are processed by innate neuromotor commands. However, direct perception theorists claim that speech perception is not different from nonspeech perception because we only need to detect information directly like all other kinds of event. It is important to grasp the fundamental idea of how human perceive articulatory events for the convergence on speech engineering. Thus, this basic review of speech perception is expected to be able to used for AI, voice recognition technology, speech recognition system, etc.

People observe lots of events around the environment and we can easily recognize the nature of an event from the resulting optic flow. The questions are how do people recognize events and what is the information in the optic flow that enables observers to recognize events. Motor theorists claim that human observers exhibit special sensitivity when perceiving events like speech or biological motion, because we both produce and perceive those events. However, direct perception theorists suggested that speech or biological motion is not special from the perception of all other kinds of event. The purpose of this review article is to address this controversy to critique the motor theory and to describe a direct realist approach to event perception. It is important to understand the fundamental information of how human perceive event perception for the convergence on robotics.

The purpose of this paper is to examine factors influencing e-Learning acceptance intention through extended Technology Acceptance Model(TAM) applying TAM, the motivation theory, and the social response theory. To do this, this paper proposes and analyzes a theoretical model consisting of factors such as perceived sociability, perceived ease of use, perceived usefulness, perceived enjoyment, and e-Learning acceptance intention. Our findings are revealed as following: First, perceived usefulness and perceived enjoyment have positive effects on e-Learning acceptance intention. Second, perceived ease of use has positive effects on determinants of e-Learning acceptance intention. Third, perceived sociability not only has direct influence on e-Learning acceptance intention but also has indirect influence carried by perceived usefulness.

The purpose of this study is to identify the factors affecting users' continuing use of Hedonic Information Systems(HIS). Focusing on users' post-adoption behaviors, this study proposes a research model which incorporates technology acceptance theory into expectation disconfirmation theory and investigates the causal relationship among five factors; perceived usefulness, perceived ease of use, disconfirmation, user satisfaction, and continuance intention to use a blog as HIS. The results show that satisfaction is significantly influenced by disconfirmation and post expectations(perceived usefulness and perceived ease of use), and in particular the impact of disconfirmation on user satisfaction is stronger than those of perceived usefulness and perceived ease of use. The results also indicate that while perceived usefulness and user satisfaction have significant impacts on continuance intention, perceived ease of use does not do so and has only an indirect impact on continuance intention through perceived usefulness and user satisfaction.

This study was conducted to identify factors that influenced teachers' adoption of digital textbooks and causal relationships among the factors identified. Chasm theory was used in developing strategies for adoption of digital textbooks that consider teachers' innovativeness. This study also employed the information technology adoption model of Davis (1989) that illustrates decision making processes for the adoption of instructional media such as digital textbooks. Based on these two theories, a measurement instrument measuring teachers' innovativeness, perceived usefulness, perceived ease of use, and intention of use was developed and validated through a series of reliability and validity tests. Causal relationships among the factors were examined using structural equation modeling. The result indicated that: a) perceived ease of use had a directional effect on perceived usefulness and an indirect effect on intention of use; and b) perceived usefulness had a direct effect on intention of use. Implications of this finding are discussed especially for the efforts in developing strategies for teachers' adoption of digital textbook. For example, when digital textbooks are introduced into public schools, teachers' perception of the usefulness of digital textbooks, beyond just ease of use, should be considered.

According to modified labeling theory, because persons with mental illness internalize the stigma of the public, they anticipate discrimination or rejection by others. Such reactions may have negative effects on both psychological and social functioning. We propose that perceived stigma are central to understanding the poor adjustment of mental patients. This study was conducted by the survey with 377 mental patients in order to discover the pathways by which perceived stigma affected life satisfaction and self-esteem. The major findings of the study were : 1) Perceived stigma has a direct effect on life satisfaction as well as indirect effect through patients' experience of discrimination. 2) Perceived stigma has no direct effect but indirectly affected self-esteem through patients' experience of discrimination and internal attribution of discriminatory situations. Based on these findings, consumer-initiated anti-stigma campaign were discussed.

This study investigated the differential effects of childhood trauma, especially neglect, emotional abuse, and physical abuse on stress perception in relation to the ToM (theory of mind), among one-hundred and fifty five college students. For this purpose, self-reported childhood neglect, emotional abuse, physical abuse, and stress levels during the previous week were measured. Social cognition was measured using a ToM questionnaire which asked respondents to guess the intentions of the person in each vignette by providing additional hints. In order to examine the predicting role of childhood trauma and mediating role of ToM, two distinct structural models assuming full (Model 1) and partial (Model 2) mediational effects were compared using structural equation modeling. The partial mediational model was supported and the main results were as follows. First, childhood neglect indirectly predicted stress perception through the effect of the ToM. Second, childhood emotional abuse directly predicted stress perception. Third, childhood physical abuse had no distinct effect on stress perception. Finally, the limitations of this study and the implications for future studies are discussed.

본 연구는 환경지향제품구매와 재활용행동을 설명하기 위한 것으로 Schwartz 가 제기한 규범이론에 관한 이론고찰과 실증분석을 병행하고 있다. 규범이론의 핵심은 사회규범을 개인의 행동으로 전환시키는 과정을 설명하는 것이다. 규범이론에 따르면 환경지향제품구매와 재활용과 같은 이타적 행동은 사람들이 일종의 추상적이고 객관적인 방식으로 동의하는 도덕적 행동에 관한 사회규범으로 시작된다. 그러나 사회규범은 행동을 지배하기에는 너무 일반적이고 소원하다. 따라서 이러한 사회규범은 개인적 차원에서 우리들 각 개인에게 적응되어 개인규범이 된다. 사회규범은 사회적 구조의 차원에서 존재하는 반면 개인규범은 강력하게 내면화 된 도덕적 태도가 된다. 개인이 규범을 내면화 했지만 이에 따라 행동하지 않을 수도 있는 데 상황에 적절하도록 개인규범이 정의되어야 한다. 규범이론은 주어진 상황에 적절하도록 사회규범을 개인규범으로 정의하도록 유도하기 위해서는 바로 행동결과지각과 책임귀인지각이 개입되어야 한다고 제기하고 있다. 본 연구는 이상의 규범이론에 근거하여 소비자의 환경지향제품구매행동과 재활용행동을 설명하고자 다음 세 가지 연구목적을 설정하였다. 첫째, 사회규범이 개인규범의 형성에 어떠한 영향을 미치는가? 둘째, 사회규범이 내면화 된 개인규범은 환경지향제품구매행동과 재활용행동에 직접적인 영향을 미치는가? 셋째, 규범이론은 조절변수가 개입되는 경우 개인규범이 행동으로 전환되는 것이 더욱 용이해진다고 제기한 바, 조절변수의 하나인 환경지향행동결과의 중요성지각의 영향을 검증하고자 한다. 연구결과, 환경문제가 개입된 상황에서 사회규범은 개인규범의 형성에 강한 영향을 미치며 개인규범은 다시 환경지향제품구매와 재활용행동에 영향을 미치는 것으로 나타났다. 그리고 환경지향행동결과의 중요성지각 역시 개인규범이 환경지향제품구매행동으로 전환되는 과정에서 조절적 역할을 함으로서 양변수간 관계를 더욱 강화하는 변수임을 연구결과는 제시하고 있다. 그러나 개인규범-재활용행동사이에서의 조절적 역할은 없는 것으로 나타났다.

This research investigates the influence of relational characteristics on 'co-defection', customer defection following salesperson turnover, in the context of salesperson-customer relationship. Based on the social exchange theory, it was hypothesized that perceived relational benefits and switching costs affect directly the customer's intentions to defect. Key constructs in relationship marketing such as customer satisfaction, trust, and loyalty were hypothesized to affect the customer's intention to defect as well as perceived relational benefits and switching costs. The results of structural equation modeling using a survey sample of 503 insurance customers who purchased life insurance policies through salespersons unveiled that the customer satisfaction with salesperson and the customer trust in salesperson strongly influence the salesperson-owned customer loyalty. However, they did not have significant direct effects on co-defection intentions. All paths from salesperson-owned customer loyalty to perceived relational benefits and perceived switching costs were also significant. Salesperson-owned customer loyalty did not have significant direct effects on co-defection intentions, but it had significant indirect effects on co-defection intentions through relational benefits and switching costs. Three sub-dimensions of perceived relational benefits had significant positive effects on co-defection intentions while the perceived switching costs had significant negative effects on co-defection intentions. The significance of our research findings were verified by comparing the hypothesized model and the rival model in the past studies.

The purpose of this study was to examine comics library user's behavioral intention using the extended theory of planned behavior. In order to verify the effects of variables, such extended variables as comics likeability and service factor were added to such basic variables of the theory of planned behavior as subjective norm, attitude and behavioral control. Study findings are as follows: user's attitude had the biggest effects on their behavioral intention of reuse of Comics Library, and it was followed by subjective norm, service quality and perceived behavioral control, in order. Comics likeability exceptionally had no direct effects on behavioral intention, but it had indirect effects via the mediation of attitude, subjective norm and perceived behavioral control. And second, comics likeability and service quality had power of explanation for such basic variables as attitude, subjective norm and perceived behavioral control, respectively, thus verifying their effects on behavioral intention as extended variables.
