This study is purposed to find the transition of the perspective connected with visual modality. The perspective based on Greek optics and euclidean geometry and rediscovered in Renaissance represents the object according to the particular moment and the point of view, is a principal fact which affect architecture, the form of a city and the spatial organization and symbolizes an ideal of the times. It embodied perception which treats the space rationally on the basis of realism and became visual modality based on the separation of the seeing subject and the world of the object. The point of view became one with the vanishing point which made up the shape and after Renaissance for four hundred years a straight line, a right angle and a circle got to be favorite geometrical choices in architecture. A fixed point of view of the subject is getting to change and break up fundamentally by the new visual technologies of the modem times.

Objective: This study was to identify whether working memory (WM) can be clearly subdivided according to auditory and visual modality. To do this, we administered the most recent and universal clinical WM measures in a mixed psychiatric sample. Methods: A total of 115 patients were diagnosed on the basis of DSM-IV diagnostic criteria and with MINI-Plus 5.0, a structured diagnostic interview. WM subtests of Korean version of Wechsler Adult Intelligence Scale-IV and Korean version of Wechsler Memory Scale-IV were administered to assess WM. Confirmatory factor analysis (CFA) was used to observe whether WM measures fit better to a one-factor or two-factor model. Results: CFA results demonstrated that a two factor model fits the data better than one-factor model as expected. Conclusion: Our study supports a modality model of WM, or the existence of modality-specific WM systems, and thus poses a clinical significance of assessing both auditory and visual WM tests.

본 연구는 손과 가까운 시각 정보의 처리적 특성이 과제전환에 미치는 영향을 살펴보기 위해 수행되었다. 최근 연구들은 손과 가깝게 제시된 정보에 대한 인지통제가 향상됨을 보고하고 있다. 이러한 인지통제 향상효과를 손 근접성과 주의의 관계를 통해 규명하고자 두 번의 실험을 실시하였다. 그 결과 과제전환 수행에서 단서와 목표자극의 감각양상에 따라 손 근접성의 효과가 달라짐을 관찰할 수 있었다. 첫 번째 실험에서 손에 근접한 자극에 대한 전환비용의 감소가 관찰되었다. 선행 연구들에서 전환비용의 감소원인으로 지목되었던 특징결합 문제를 제외시켰을 경우에도 동일한 결과가 관찰되었다. 즉, 손 근접성이 전환비용을 감소시켰음을 검증할 수 있었다. 두 번째 실험에서는 손 근접성과 감각양상의 상호작용이 전환비용에 미치는 영향을 살펴보기 위해 수행되었다. 과제전환에서 목표자극은 시각으로 단서는 시각 또는 청각으로 제시하였고, 단서의 준비성 효과를 관찰하기 위해 단서-목표자극 간격을 조변하였다. 연구 결과 손에 근접한 시각 단서는 과제 준비 시간을 단축시켜 전환비용을 감소시켰으나, 청각 단서의 경우 손에 근접할 때 오히려 과제 준비 시간이 더 오래 걸렸다. 시각 단서의 결과는 손에 근접한 시각 정보에 대한 신속한 주의정향으로 인한 이득으로 설명될 수 있다. 반면에 청각 단서에서 나타난 손실은 청각 단서와 시각 자극 간의 감각 간 전환이 손 근접성의 주의 범위 고정 효과로 인해 방해된 결과로 해석될 수 있다. 마지막으로 손 근접성의 주의효과로 인해 달라지는 전환비용에 대해 논의하였다.

INTRODUCTION Interaction between temporal events at the millisecond level is important for visual and tactile interaction. OBJECT The aim of the present study is to identify any neural signature, as reflected in event-related potentials (ERP), for the integrative processes when the two sensory modalities are stimulated in synchrony as opposed to when they are stimulated separately. METHOD The basic strategy was to compare ERP signals obtained with simultaneous visual and tactile stimulation with a linear summation of ERP patterns obtained with each modality stimulated separately. Condition were presented, paired with various stimulus-onset-asynchronies (SOA) ranging from - 300 ms (tactile-first) to 300 ms (visual-first), and in trials where only one modality was stimulated alone. RESULT A positive deviation was located in observed ERP at C4 electrode (contralateral to the stimulated hand) at 200-400 ms, in comparison to the predicted ERP. The deviation was present at all SOAs other than -300ms (tactile-first) and 300 ms (visual-first). There was also a positive deviation at occipital leads at the 50-ms SOA (visual-first) trials. DISCUSSION It suggested that neural signatures of cross-modal integration occur within a limited time-window. The deviations were specifically localized at the contralateral somatosensory and visual cortices, indicating that the integration happens at or before the level of the primary cortices.

본 연구는 참가자 간 상관(Intersubject correlation: ISC)기법을 통해 정서 유발 자극에 대한 한 참가자의 반응과 그 참가자를 제외한 나머지 참가자들의 반응 간 일치성이 각 정서표상 범주(지배가, 각성가, 정서가)와 다양한 감각양상(청각, 시각, 촉각)에서 어떠한 차이가 있는지 밝히고자 하였다. 참가자 간 상관을 계산하기 위해 사용된 데이터는 참가자들의 청각, 시각, 촉각 자극에 대한 생리 측정치와 정서 평정치로 구성되었으며, 한 참가자의 데이터 세트와 나머지 참가자들의 데이터 세트의 평균으로 구분한 뒤 가능한 모든 자극 쌍에 대해 상관을 구하는 방식으로 참가자 간 상관을 계산하였다. 연구 결과, 지배가를 기준으로 재정렬한 데이터 세트에 대한 참가자들의 반응 일치성은 청각 감각양상 조건보다 시각 감각양상 조건에서 높은 ISC 값을 얻었다. 다음으로 각성가로 재정렬한 데이터 세트의 경우 시각 감각양상과 청각 감각양상에서 차이가 있음은 같았지만, 지배가 기준으로 재정렬한 데이터 세트와 결과가 상반되었다. 마지막으로, 정서가를 기준으로 재정렬된 데이터 세트는 모든 감각양상에서 부정적인 데이터 세트들이 긍정적인 데이터 세트보다 참가자들의 반응 일치성이 더 높았다. 모든 데이터 세트에서 정서표상 범주의 높고 낮음과 상관없이 촉각 감각양상에서 높은 ISC 값을 얻었다. 본 연구의 결과는 참가자 간 상관의 다양한 감각양상과 정서표상에 대한 반응의 일치성이 의미하는 바에 대한 해석을 제시하며, ISC 분석 방법이 참가자 반응의 차이에 대한 패턴을 측정하는 유용한 도구가 될 가능성을 제시하였다.

CBIR is an effective tool to search and extract image contents in a large remote sensing image database queried by an operator or end user. However, as imaging principles are different by sensors, their visual representation thus varies among image modality type. Considering images of various modalities archived in the database, image modality difference has to be tackled for the successful CBIR implementation. However, this topic has been seldom dealt with and thus still poses a practical challenge. This study suggests a cross modality CBIR (termed as the CM-CBIR) method that transforms given query feature vector by a supervised procedure in order to link between modalities. This procedure leverages the skill of analyst in training steps after which the transformed query vector is created for the use of searching in target images with different modalities. Current initial results show the potential of the proposed CM-CBIR method by delivering the image content of interest from different modality images. Despite its retrieval capability is outperformed by that of same modality CBIR (abbreviated as the SM-CBIR), the lack of retrieval performance can be compensated by employing the user's relevancy feedback, a conventional technique for retrieval enhancement.

Objective: This study aimed to identify children's cognitive processing and performance characteristics while multiple task performance. It confirmed whether their multiple task performance and psychological refractory period (PRP) varied by task condition (stimulus onset asynchrony [SOA] and task difficulty) and stimulus modality. Methods: Seventy 5-year-olds were recruited. Multi-task tools were developed using the E-prime software. The children were required to respond to two stimuli (visual or auditory) presented with microscopic time difference and their response times (RTs) were recorded. Results: As the SOA increased, the RTs in the first task increased, while the RTs in the second task and PRP decreased. The RTs of the first and second tasks, and the PRP for difficult tasks, were significantly longer than those for easy tasks were. Additionally, there was an interaction effect between the SOA and task difficulty. Although there was no main effect of stimulus modality, task difficulty moderated the modality effect. In the high difficulty condition, the RTs of the first and second tasks and PRP for the visual-visual task were significantly longer than those for auditory-auditory task were. Conclusion: These results inform theoretical discussions on children's multi-task mechanism, and the loss of multiple task performance. Additionally, they provide practical implications and information on the composition of multi-tasks suitable for children in educational environments.

I report on the case of a polyglot ‘savant’ (C), who is mildly autistic, severely apraxic, and of limited intellectual ability; yet who can read, write, speak and understand about twenty languages. I outline his abilities, both verbal and non-verbal, noting the asymmetry between his linguistic ability and his general intellectual inability and, within the former, between his unlimited morphological and lexical prowess as opposed to his limited syntax. I then spell out the implications of these findings for modularity. C's unique profile suggested a further project in which we taught him British Sign Language. I report on this work, paying particular attention to the learning and use of classifiers, and discuss its relevance to the issue of modality: whether the human language faculty is preferentially tied to the oral domain, or is ‘modality-neutral’ as between the spoken and the visual modes.
