This study was aimed to verify moderated mediation effect between cognitive-flexibility and subjective economic status in the process that aging anxiety have an effect on psychological well-being. For this, online survey was conducted to 317(M:159, F:158) adults who ranged from 40 to 64 years old. Survey was conducted from 2017.9.3. to 9.28. Correlation analysis, regression analysis, and significant test was done through SPSS 21.0 and SPSS Macro. First, the analysis showed that meaningful correlation was found among aging anxiety, cognitive flexibility, subjective economic status and psychological well-being. Secondly, cognitive flexibility was found to have meaningful partial mediation effect(β = .530, p < .001) in the relationship between aging anxiety and psychological well-being. Thirdly, subjective economic status was found to have a meaningful moderation effect(β = .080, 𝜟R²=.006, p <.05) in the relationship between cognitive flexibility and psychological well-being. Fourthly, verification result by SPSS Macro showed that, mediation effect of cognitive flexibility and subjective economic status was existent in the relationship of aging anxiety and psychological well-being. Lastly, implications and limitations of this study and suggestions for future studies were discussed.

Augmented reality (AR) and virtual reality (VR) differ fundamentally, with AR overlaying computer-generated information onto the real world in a nonimmersive way. Despite extensive research on cybersickness in VR, its occurrence in AR has received less attention (Vovk et al., 2018). This study examines cybersickness and discomfort associated with AR usage, focusing on the impact of content intensity and exposure time. Participants viewed 30-minute racing simulation game clips through AR equipment, varying in racing speed to alter content intensity. Cybersickness was assessed subjectively using the Simulator sickness questionnaire (SSQ; Kennedy et al., 1993). Findings revealed a progressive increase in cybersickness with longer exposure, persisting even after removing the AR equipment. Contrarily, content intensity did not significantly influence cybersickness levels. Analysis of the SSQ subscales revealed higher oculomotor (O) scores compared to nausea (N) and disorientation (D), suggesting that discomfort primarily stemmed from oculomotor strain. The study highlights distinct differences in user experience between AR and VR, specifically in subjective responses.

Using a psychometric paradigm, risk perception of 30 hazards was investigated for three social groups-college students, experts of technologies, and employees of environmental organizations. The aim of this study was to examine psychological dimensions of risk perception, namely, to replicate the psychological dimensions - dread and knowledge -, which Slovic et al(1978; 1984; 1987) found and to forker explore discrepancies between societal groups. The results confirmed the same psychological dimensions Slovic et al have found. However, there are a number of significant differences in perceived risk such as perceived social benefits and other risk characteristics between three groups that suggest differences in ecological attitudes. The results were compared with those of Slovic et af and the nature of differences in risk perception among three groups were discussed.

This study aims to examine the effect of Convergence Tailed Occupational Therapy Activities Program (CTOTAP) which is customized to elderly people with mild cognitive impairment on their mental stability and social participation. A total of thirty elderly patients with mild cognitive impairment were randomly divided into a test group and a control group of 15 patients each, undergoing a total twelve sessions of the program (two sessions per week for six weeks) in three steps. In order to investigate the mental stability of the patients before and after the program, the Korean Geriatric Depression Scale (KGDS) was used while the Frenchay Activity Index (FAI) was used to explore the social participation of the patients. According to the findings of this study, there appeared to be an increase in the mental stability, social participation of the test group after the program. In addition, after the program there were differences between the test group and the control group in all of the mental stability and social participation. Therefore, the study has shown that the CTOTAP with customization has positive impact on the mental stability and social participation of patients with mild cognitive impairment.

단어 인지과정은 언어 이해과정의 한 부분으로, 신속성과 정확성 그리고 심성어휘집을 그 특정으로 한다. 표기 단어의 인지과정에는 그 언어의 정서법 체계가 반영된다. 한국어의 단어 인지과정에 대한 모델 작성의 예비 연구로 음운적 처리와 어휘 근접에서의 정서법적 정보의 역활에 대해 검토하였다. 어휘 근접의 단위에 대한 논의에서는 음절, 자질, 단어등의 형식적 언어학적 단위외에 심리적 단위가 고려되어야 함이 지적되었으며, 그 심리적 단위들과 정서법의 관계에 대해 논의하였다. 마지막으로 한글 단어 인지과정에 관한 한 모델로서 상호작용 활성화 모델의 가능성에 주목하였다.

최근 및 년 사이에 수학교육에 대한 연구는 광범위하게 이루어지고 있다. 이러한 수학교육의 문제는 크게 Piaget의 인지이론에 근거한 연구와 정보처리 이론을 바탕으로 한 인지심리 학자들의 연구에 근거하고 있다. 지금까지 연구되어 발표된 학습이론에 대한 논문들을 보더라도 이러한 경향을 쉽게 알 수 있을 것이다.(중략)

This paper describes a method for sinusoidal modeling of audio signals using perceptually weighted matching pursuit. Matching pursuits extracts iteratively the greatest energy signals from the input signals until the residual between the original and the reconstructed signal is zero. In this paper, perceptual matching pursuits using psychoacoustic model to matching pursuit extracts greatest perceived energy iteratively. To evaluate the performance of the perceptual matching pursuits it is compared with the sinusoidal matching pursuits which is not included perceptual weighting. For various audio signals the result of simulation shows that the perceptual matching pursuit is superior to the sinusoidal matching pursuits, especially for a high change rate in time domain it can synthesized original signal.

This research aims to study Michael Chekhov's acting techniques scientifically, because his techniques has been studied only theoretically or empirically. Especially, this study focuses on 'imagination' and 'Psychological Gesture' from the perspective of cognitive psychology. Chekhov thought 'imagination' as the basis and core of all the works of acting. In cognitive psychology, it is called as 'imagery' and means 'a representation of the mind of the object not communicated by the sensory organs currently'. This study starts with defining imagery and takes a brief look at the features and kinds of imagery. Then the researcher will prove scientifically the possibility of training acting using imagery as Chekhov's assertion. For the proof of the validity of imagery, we'll look for the theoretical evidences-functional equivalence hypothesis, psychoneuromuscular theory, symbolic learning theory, psychophygiological information processing-and experimental ones-measurements of cerebral blood flow or event-related potential, experiments with fMRI(functional magnetic resonance imaging) or PET(positron emission tomography). As a result, we can see that imagery is functionally identical to perception and improves fulfillment of cognitive and physical tasks. As proving physical changes can draw out psychological changes(feeling) on the medium of imagery, we can also see the validity of Psychological Gesture. From the above research, even if Chekhov developed the acting techniques only on the basis of his experience, his techniques can be thought as having scientific validity. Though insufficient, this study can be a help for actors or students as they using Chekhov's techniques.

인간의 지식 표상 규명에 대한 연구는 인간을 대상으로 연구하는 심리학에서뿐만 아니라 인간의 지능을 컴퓨터를 이용하여 구현하고자 하는 인공지능 학문에서도 오래 전부터 매우 중요한 화두가 되고 있다. 특히 인간의 지식 중 언어 지식에 대한 연구는 인간의 언어처리 과정 및 현상을 규명하고 이해하고자 하는 심리언어학에서뿐만 아니라 인간의 언어를 컴퓨터를 이용하여 처리하고자 하는 전산언어학 연구에 있어서도 매우 중요하다. 본 논문은 피험자를 대상으로 한 어절 재인 시 관찰되었던 언어 현상을 설명할 수 있는 시뮬레이션 모델과 이에 근거한 심성어휘집내에서의 한국어 어절의 표상 구조를 제안한다.
