Recent developments in embodied cognition suggest that people process environmental information by using their bodily state and mental simulation. The focus of embodiment theory is that cognitive processing is based on the interaction among the body, the mind, and the world. Based on embodied theories of cognition, the authors predict that when the representation of marathon running is activated, bodily feedback such as tiredness and thirst will occur because mental simulation of marathon running contains sensorimotor representation of marathon running. As a result, it is predicted that participants primed with marathon runner will have more desire to have products that enable thirsty-quenching. Specifically, this research proposes that consumers' tendency to adopt the perspective of others influences embodied cognition, since perspective taking leads people to assimilate their own self-judgments and behaviors toward the cognitive representations of others. An experiment reveals that both perceptual and cognitive perspective taking tendencies moderate how participants respond to the contextual cues. The effect of perspective taking is moderated by whether participants are prompted to adopt a first-person view or a third-person view. In detail, among the high perspective takers, those in the marathon-first-person condition drink more the mineral water than those in the marathon-third-person condition, who in turn drink more the mineral water than those in the control condition. Among the low perceptual perspective takers, however, there are no significant differences in the amount of mineral water intake. This research delivers important insights for advertising messages. When being exposed to an advertisement, high perspective taking consumers may be more engaged in the advertised message than low perspective taking consumers, which in turn high (vs. low) perspective taking consumers' tendency to respond behaviorally consistent with the message may be higher. Based on the findings of this research, if the message induces the high perspective taking consumers to have a first- (vs. third-) person view, this effect may be stronger. Moreover, if the advertising message contains behaviors, such as using the target product, inducing consumers to mimic the behaviors seems to bring more behavioral responses which marketers intend.

This study investigated how the degree of attention modulates English learners' perception of Korean stop contrasts. The contributions of VOT and F0 in perceiving Korean stops were examined while availability of attentional resources was manipulated using a dual-task paradigm. Results demonstrated the attentional modulation in the use of VOT, but not in F0: under less attention, the contribution of VOT to the perception of aspirated stops decreased, whereas that of lenis stops increased, which suggests more native-like performance. This implies that the role of attention in perceiving non-native contrasts might differ depending on how equivalent the acoustic and perceptual cues are between L1 and target L2 contrasts.

A lax stop in Korean, one of the three laryngeal contrastive stops, has undergone a sound change in terms of its acoustic properties. Prior production studies described this recent lax stop as being differentiated from tense and aspirated stops primarily by fundamental frequencies (f0). And, the acoustic property of voice onset time (VOT) further separates tense stops from lax and aspirated stops. The current research explores how these two major acoustic parameters of f0 and VOT cue the three stop categories in Korean adult listeners' perception. Thirty-one native speakers of Korean participated in two experimental tasks: categorization judgment and within-category goodness ratings. Two sets of audio stimuli were prepared by synthesizing English and Korean male speakers' CV productions. The findings showed that while f0 cues listeners to lax stops as production patterns would predict, VOT were closely related to listeners' categorization and goodness ratings of lax stops. This suggests that accurate characterizations of the recent lax stop category need to be based on Korean speakers' perceptual behavior as well as production patterns.

We propose a DP-based formulation for matching line patterns by defining a robust and stable geometric representation that is based on the conceptual organizations. Usually, the endpoint proximity and collinearity of image lines, as two main conceptual organization groups, are useful cues to match the model shape in the scene. As the endpoint proximity, we detect junctions from image lines. We then search for junction groups by using geometric constraint between the junctions. A junction chain similar to the model chain is searched in the scene, based on a local comparison. A Dynamic Programming-based search algorithm reduces the time complexity for the search of the model chain in the scene. Our system can find a reasonable matching, although there exist severely distorted objects in the scene. We demonstrate the feasibility of the DP-based matching method using both synthetic and real images.

Text in images is one of the most important cues for understanding a scene. In this paper, we propose a novel approach based on interest points to localize text in natural scene images. The main ideas of this approach are as follows: first we used interest point detection techniques, which extract the corner points of characters and center points of edge connected components, to select candidate regions. Second, these candidate regions were verified by using tensor voting, which is capable of extracting perceptual structures from noisy data. Finally, area, orientation, and aspect ratio were used to filter out non-text regions. The proposed method was tested on the ICDAR 2003 dataset and images of wine labels. The experiment results show the validity of this approach.

기존의 사회인지와 정서 연구들은 주로 얼굴자극을 이용하여 초기지각단계 및 후기인지과정에의 정서 효과를 조사해 왔다. 그러나, 정서의 효과가 정보처리과정의 각 단계에서 어떤 양상으로 나타나는지와, 정서유형에 따른 효과 양상의 변화 여부는 불확실하다. 본 연구에서는 얼굴 대신 생물형운동자극을 이용해 자극에 내포된 행복, 분노, 중립정서가 지각과제와 작업기억과제 수행에 미치는 영향을 조사하였다. 참가자는 연달아(지각과제) 또는 시간차를 두고(작업기억과제) 제시되는 두 생물형운동의 동일 여부를 판단하였다. 지각과제에서는 정서가를 가진 자극 시행의 정확도가 중립정서자극에 비해 낮아 정서정보가 초기지각처리에는 부정적 영향을 미치는 것으로 보였으나, 작업기억과제에서의 기억정보유지에는 도움이 되는 것으로 나타났다. 또한, 각 과제에서 정서유형에 따라 다른 수행 양상이 관찰되었다. 분노정서는 지각단계에서 더 많은 정신적 자원을 요구하여 부하가 증가할 경우 정확도가 낮아지지만 기억유지에는 긍정적으로 작용하는 것으로 보이며. 행복정서의 경우 중립정서가 이어서 제시될 때 이를 행복정서와 유사하게 처리하려는 편향을 유도하는 것으로 보인다. 본 연구는 생물형운동자극을 이용하여 정보처리과정에서의 정서 영향을 재확인하였고, 처리단계별 및 정서 종류별로 다른 양상의 영향이 나타난다는 점을 추가로 밝혀, 정서정보의 정교한 조작 및 통제를 위한 유용한 단서를 제공한다.

This study aimed to examine how Korean-English bilinguals make use of VOT and F0 cues in perception and production of Korean (lenis vs. aspirated) and English (voiced vs. voiceless) stops. It was explored whether bilinguals with extensive experience living in the U.S. exhibit native-like or interactive patterns in the cue use for both languages. Participants produced monosyllabic word-initial stops within a carrier sentence in each language, and performed forced-choice identification tasks with synthesized stimuli varying in 7 VOT steps and 7 F0 steps with base tokens of /$t^han$/ for Korean and /$t{\ae}n$/ for English. Listeners were required to select either /tan/ or /$t^han$/ for Korean and either /$d{\ae}n$/ or /$t{\ae}n$/ for English. The results from binary logistic regression analyses for each listener indicated that all bilinguals placed greater weight on F0 than VOT when distinguishing between the Korean lenis and aspirated stops, and greater weight on VOT than F0 in distinguishing between the English voiced and voiceless stops. In terms of production, all participants showed remarkably overlapping ranges in the VOT dimension and separating ranges in the F0 dimension for the stop contrast of Korean, while forming overlapping ranges in the F0 dimension and separating ranges in the VOT dimension for the stop contrast of English. These results indicate that the bilinguals with extensive exposure to L2 manage the stop systems of the two languages independently, both in perception and production, employing the opposite cue use for stops in the two languages. It was also found that the absolute beta-coefficient values of the perceptual cues for Korean stops were generally smaller than those for English and those reported in a previous study as for later bilinguals, which may have resulted from Korean not being their dominant language.

Nineteen stimulus photograghs varied in hue and color scheme of one clothing style of Korean dress worn by a female were used to investigate the effect of color color scheme and structure on impression formation for Korean dress. Subjects were 77 male and 86 female undergraduate and graduate students. The stimuli c9onsisted of two sets(cool and warm) of four similar color schemes two sets (cool and warm in Chima color) of five contrasting color schemes and one extra stimulus triad 3 hue base. Structures were de-fined by color schemes of Kit.Korum toward the color schemes of Jokori and Chima. Stimu-lus photogragh selected from Korean dress fashion magazines was managed and varied in hues and color schemes to Kit Korum Jokori and Chima according to Korean Standard Color through scanning and Adobe photoshop 3.0 program and then pictured through slide printer(HR-6000). Each subject assessed 19 stimulus color photographs with incorporated 7 point semantic differential response scale. The data were analyzed by frequency mean factor analysis t-test ANOVA and Scheffe test. Results indicate impression ofrmations are af-fected by clothing cues. 1) Four factors emerged to account for dimensional structure of impressions of female features on Korean dress. These four factors were titled as(1) preference.evaluation (2) individuality.attention (3) youth and (4) friendshio. The preference.evaluation factor was the largest including eleven adjectives and accounting for 29.62% of the variances. 2) Almost every clothing cue(color, color scheme, structure) had some effects on im-pressions formed But the color of Chima did not form the effects on impression of prefer-ence.evaluation factor. The effect of related color scheme was the most influential clothing cue on impressions of preference.evalation factor and friendship factor whereas the ef-fect of contrasting color scheme was the most influential clothing cue on impressions of indi-viduality.attention factor and youth factor. The effect of cool color of Chima was the most influential clothing cue on impression of indi-viduality.attention factor whereas the effect of warm color of Chima was the most influen-tial clothing cue on impressions of youth factor and friendship factor. The effect of Jokori/Chima.Kit.Korum structure was the most influential clothing cue on impressions of pref-erence.evaluation factor and youth factor whereas the effect of Kit.Korum/Jokori.Chima structure was the most influential clothing cue on impressions of individuality.attention factor and friendship factor. 3) The interaction effects were appeared among clothing cues. Significant interaction effects between color schemes(similar and contrasting) and colors of Chima(cool and warm were appeared on impressions of prefer-ence.evaluation factor imdividuality.atten-tion factor and friendship factor, Significant interaction effects between color schemes (similar and contrasting) and structures (Jokori.Chima.Kit.Korum; Jokori.Kit.Koru-m/Chima;Jokori/Chima.Kit.Korum;Kit.Korum/Jokori.Chima) were appeared on impressions of preference.evaluation factor youth factor and friendship factor. Signifi-cant interaction effects between colors(cool and warm) and structures were appeared on impressions of individuality.attention factor youth factor and friendship factor. Sighifi-cant interaction effects between colors(cool and warm) and structures were appeared on impressions of individuality.attention factor youth factor and friendship factor. Significant interaction effects among clothing cues(color color schemes and structures) were appeared on all impression factors. The friendship factor was the most friquently affected impression factor by interaction effects among clothing cues. In summary the clothing was used as nonverbal cues in the effect on impression for-mation of female dressed in Korean dress. it concluded that color schemes worked as cen-tral traits and colors of Chima and structures worked as peripheral traits in the formation of impression of the female clothed in Korean dress. hence organizing our impressions with respect to the parts of the Korean dress in re-lation to the whole holistic perceptual pro-cess Gestalt approach was used and supported.
