색채에 따른 목표자극과 방해자극의 분리가 2차원 운동지각을 향상시킨다는 연구결과(Stoner & Albright, 1997)와 색채에 따른 목표자극과 방해자극의 분리가 2차원 운동지각을 향상시키지 못한다는 상반된 연구결과(Edwards & Badcock, 1996)의 모순을 해결하고, 선택적 주의에 따른 목표자극과 방해자극의 분리가 2차원 운동지각에 미치는 영향을 연구하기 위하여 일련의 실험이 수행되었다. 이러한 연구문제에 대한 이형철(1999)의 연구가 있었지만, 이형철의 연구는 단지 숙련된 2명의 피험자의 결과에 의존했다는 점, 그리고 선택적 주의에 사용된 자극에서 목표자극과 방해자극이 색채에 의해 완벽하게 분리되지 않을 때와 목표자극과 방해자극이 색채정보에 의해서만 분리되고 그 외의 다른 정보에 의하여 분리되지 않을 때와 목표자극과 방해자극이 그 어떤 정보에 의해서도 분리되지 않을 때, 피험자들의 2차원 운동지각 수행은 비슷하였다. 하지만, 목표자극과 방해자극이 색채정보에 의하여 분리되고 피험자들이 목표자극을 구성하는 색채에 선택적 주의를 기울일 때, 피험자들의 2차원 운동지각 수행은 향상되었다. 이러한 실험결과는 선택적 주의가 개입되지 않는 한 인간의 운동지각체계는 자극 구성요소들을 운동정보분석을 위해 색채에 따라 자동적으로 grouping 하지 않음을 의미한다

The main objective of this paper is to examine critically White's claim that there is a conflict between Perceptual Dogmatism and Bayesian Theory of Confirmation. For this purpose, this paper is structured as follows: In Section 2, I will introduce White's argument. Section 3 is dedicated to explaining some elements of Bayesian Theory of Confirmation. In particular, I will provide an explanation of confirmation measures and Bayesian Favoring. Using these two conceptual apparatuses, it will be shown that, contrary to what White has thought, there is a way of supporting Perceptual Dogmatism by means of Bayesian Theory of Confirmation - in particular, Bayesian Theory of Favoring.

Selective attention induces perceptual distortions. ranging from repulsion of objects located near the attended area(Suzuki & Cavanagh. 1997) to magnification of the u unattended objects (Tsal & Shalev. 1996). Two hypothetical mechanisms have been p postulated: a shift of receptive fields' positions away from the locus of attention(receptive-field-recruitment hypothesis) or the enlargement of perceived space around the a attended location(space-enlargement hypothesis). The present study distinguished between these hypotheses by investigating the spatial and temporal properties of attention-induced d distortions. Perceptual judgements on vernier alignment. line tilt. line length were used to measure attention-induced changes in perception. Attention was induced exogenously(by blinking a specific set of dots around the test stimuli} or endogenously(by instructing the subject to selectively attend the dots). After inducing attention. the test stimuli were briefly flashed. A staircase method was used to measure the attentional effect. A vertical line was perceived as repelled from the locus of attention. and a line segment appeared longer when attention was given to its vicinity. The effects decreased as the distance between the locus of attention or the time between the onset of attention and the stimulus presentation increased. The results imply that the space-enlargement hypothesis provides a better explanation for the attention-induced changes in perception than the receptive-field-recruitment hypothesis.

The purpose of this study was to investigate the effect of aging on visuo-spatial attention allocation ability and emotional perception bias. We used the useful field of view (UFOV) task to measure the visuo-spatial attention allocation ability and the emotional perception task to measure positive and negative emotional perception bias. A total of 48 participants took part in this study with 23 participants in the senior group and 25 in the junior group. The senior group showed slower response time and lower accuracy than the junior group in the UFOV task, indicating that the senior group had lower visuo-spatial attention allocation ability than the junior group. In the emotional perception task, the senior group showed both positive and negative emotional perception bias more than the junior group. The correlation analysis showed that the negative emotional perception bias for accuracy in the emotional perception task showed a positive correlation with the response time to the stimuli presented in the visual angle 30° in the UFOV task (r=.289). In addition, positive emotional perception bias for the accuracy in the emotional perception task showed a positive correlation with the accuracy of the stimuli presented in the visual angles 10°, 20°, and 30° in the UFOV task (r=.305, r=.322, and r=.299, respectively). However, it showed a negative correlation with the response time of the stimuli presented in the same location in the UFOV task (r=-.345, r=-.295, r=-.308). These results suggest that aging is associated with a decrease in the visuo-spatial attention allocation ability and perceptual bias toward positive and negative emotions. In addition, the positive and negative emotional perception biases associated with aging are potentially related to the reduced visuo-spatial attention allocation ability.

Three experiments compared two hypotheses on visual selection; perceptual load hypothesis and dilution hypothesis. The perceptual load hypothesis predicts that perceptual load of task-relevant processing determines the level of task-irrelevant processing whereas the dilution hypothesis predicts that competition for limited-capacity attentional resource, not perceptual load, determines the locus of selection. To compare the two hypotheses, we investigated the influence of perceptual load in visual search on response interference by a distractor. Experiment 1 and 2 manipulated perceptual load by the set size of a search array and the colors of a target and non-targets, respectively. As a result, distractor interference decreased with a set size regardless of perceptual load. In order to further test the set size effect, Experiment 3 manipulated the perceptual categories of non-targets and a distractor. The results showed that distractor interference decreased only when non-targets belonged to the same category as a distractor. Overall, the current findings support the dilution hypothesis, but not the perceptual load hypothesis, and provide the evidence that visual selection is constrained by capacity-limited, category-specific attentional resources.

The effect of spatial attention gradually decreases as a function of the distance between the locus of attention and a target. According to this hypothesis, we tested the spatial-effect profile of visual attention when it operates on perception and memory. Experiment 1 measured accuracy of discriminating the color of a simultaneously masked target after presenting a pre-cue to either at the target location or away from the target (perception-intensive task). Experiment 2 measured accuracy of recognizing the color of several items at and around the pre-cued location (memory-intensive task). In the perception-intensive condition, the accuracy gradually dropped as the distance between the cue and target location increases. However, in the memory-intensive condition, subjects remembered only the item at the cued location. This suggests spatial attention in a memory-intensive process would operate on object-based representations. Experiment 2 showed the object-based effect observed in Experiment 1 can be also present in perception under a special circumstance. The results indicate that spatial attention can operate on object-based representations in a memory-intensive process whereas it flexibly can operate either on location-based or object-based representations in a perception-intensive process.

While strategic alliance of multinational corporation has boost, opportunistic behavior is also increased recently. This study examines the cause of opportunism in strategic alliance by focusing on the development of opportunistic behavior, a process in which resource complementarity and risk perception decides attitudinal direction, ultimately leading to opportunism. Empirical test based on 257 alliance participants shows that risk perception had a greater influence on firms' attitudinal and behavioral directions compared to benefit perception. Notably, relational risk heavily influenced firms' competitive attitude and opportunistic behavior. Finally, the study concludes that firms' competitive and independent attitude caused by risk perception negatively influence alliance outcome. Based on the results, it is drawn that alongside the external tools such as surveillance, control, monitoring or legalistic pleas, management of risk perception during the alliance process has significance influence on the achievement of alliance goals.

This study examined the possible mediating effects of emotion-focused coping and perceived efficacy on the relation between evaluative concern perfectionism and psychological distress. A convenience sample of 241 university students (129 men and 112 women) was employed. Analyses of the structural model for the full sample yielded evidence of good fit. The results support the indirect pathways of evaluative concern perfectionism to psychological distress through emotion-focused coping and perceived efficacy. About 40% of variance in psychological distress was accounted for by evaluative concern perfectionism, emotion-focused coping and perceived efficacy. In addition, the fully mediated model produced good fit to the data across gender. However, there were no differences in structural paths as a function of gender. Implications for counseling practice and future research are discussed.

The purpose of this paper is to critically investigate John McDowell's naturalism, and propose an alternative direction of inquiry in order for his naturalism to have a more explanatory cogency. McDowell's main project is to settle a philosophical anxiety that has made traditional philosophy waver between mind and world. If one stands on the world side, he would appeal to "the unintelligible given," and on the other hand, if one stands on the mind side, he would fall into anarchistic relativism. In order to relieve the traditional philosophical anxiety, what McDowell has in mind is to reintroduce an empiricistic intuition into a pragmatic conceptual setting. Although McDowell is successful in that it could avoid methodological difficulties with which traditional philosophy has faced, his discussion seems to give rise to a charge of "the Myth of the Given," presenting perceptual judgement as a model of judgement. I propose that McDowell has yet to account for the relation between perceptual and abstract judgements in a more cogent way, which has been far better explained by the experientialist account of the nature and the structure of the embodied experience.
