  • 시각 정보와 청각 정보가 동시에 제시될 때, 두 정보가 모두 지각되기 보다는 시각 정보가 더 우세하게 지각되는 현상을 보게 된다. 이러한 현상을 시각 우세성 효과라고 한다. 이러한 시각 우세성 효과에 각 정보의 의미적 일치여부의 속성이 어떠한 영향을 주는 지를 살펴보고자 하는 것이 본 연구의 목적이다. 이에 목표자극이 되는 시각 정보와 청각 정보의 의미적 속성이 서로 일치하는 조건과 불일치하는 조건으로 구분하여 살펴보았다. 그 결과, 오류율의 분석에서는 의미적 일치 여부에 따라 시각 우세성 효과의 변화는 나타나지 않았으나, 반응시간의 분석에서는 의미적 일치 여부에 따라 시각 우세성 효과의 변화가 나타났다. 이는 과제의 특성에 따라 의미적 일치성이 시각 우세성에 미치는 효과가 달라질 수 있음을 시사하는 것이다.

  • A simulation study on detection of linkage between genetic markers and QTL in backcross design was conducted. The effects of various sample sizes and the degree of QTL dominance on detention of linkage were examined by using a simple regression analysis. The results indicated that as sample size increased, the standard error of the estimated slope became smaller. When the dominance effect of QTL was complete, the estimated slope tended to be negative but was statistically not significant at all with type I error of greater than 50%. With complete linkage between genetic Marker and QTL, the estimated intercept value was smallest but the estimated slope was largest as expected. In most cases with various degree of dominance and sample sizes, when the actual recombination rate became larger, greater values were obtained for the slope except in the case of complete dominance of QTL.

  • Recenlty, the category of luxury wearbles has expanded and the relevant reseach has been scarce. The study tests whether the emotional mechanism regarding luxury wearables within e-tail affects luxury brand perceptions. Furthermore, it tests the moderation effect of gender in the mechanism. A total of 393 responses from U.S. populations were collected through an international research company with using online survey methods. In the results, the positive and direct effect of dominance on positive emotion was significant, and the positive emotion significantly increases perceived brand luxury. However, no direct effect of dominance was found on perceived brand luxury. The moderation effect of gender in the relationship between positive emotion and perceived brand luxury was found positive and significant, but the hypothesized moderation effect of gender was insignificant in the relationship between dominance and perceived brand luxury. Implications and study limitations are discussed.

  • 최근 들어 데이트 폭력의 심각성이 사회적 문제로 부각되고 있으나, 데이트 폭력 유형 가운데 통제행동에 관한 연구는 매우 부족한 실정이다. 본 연구에서는 특권의식과 통제행동 간의 관계를 살펴보고, 특권의식이 통제행동에 미치는 영향에서 사회지배경향성과 사회비교경향성의 매개효과가 있는지 알아보았다. 또한, 성차가 있는 것으로 알려진 사회지배경향성의 경우, 특권의식과 통제행동 간의 관계에서 성별에 따라 매개효과가 다르게 나타나는지를 살펴보았다. 그 결과, 특권의식이 높을수록 사회지배경향성 및 사회비교경향성이 강하며, 통제행동을 더 많이 하는 것으로 나타났다. 더불어, 사회지배경향성 및 사회비교경향성 이 강할수록 통제행동을 더 많이 하였다. 특권의식이 통제행동에 미치는 영향에서 사회지배경향성이 완전 매개역할을 하였다. 또한, 특권의식과 통제행동 간의 관계에서 사회비교경향성의 하위요인 중 하나인 능력비교경향성이 완전매개역할을 하였다. 더불어, 특권의식이 사회지배경향성을 매개로 통제행동에 미치는 영향이 성별에 따라 조절되었다. 즉, 특권의식과 통제행동 간의 관계에서 남성의 경우에는 사회지배경향성의 매개효과가 유의하였으나, 여성의 경우에는 유의하지 않았다. 본 연구의 한계점을 논의하고 후속연구에 대해 제안하였다.

  • Additive and dominance genetic variances were estimated for purebred Landrace selected with line breeding from 1989 to 1995 at Miyazaki Livestock Experiment Station, Kawaminami Branch. Ten body measurements, two reproductive traits and fifteen carcass traits were analyzed with single-trait mixed model analysis. The estimates of narrow-sense heritabilities by additive model were in the range of 0.07 to 0.46 for body measurements, 0.05 to 0.14 for reproductive traits, and 0.05 to 0.68 for carcass traits. The additive model tended to slightly overestimate the narrow-sense heritabilities as compared to the additive and dominance model. The proportion of the dominance variance to total genetic variance ranged from 0.11 to 0.91 for body measurements, 0.00 to 0.65 for reproductive traits, and 0.00 to 0.86 for carcass traits. Large differences among traits were found in the ratio of dominance to total genetic variance. These results suggested that dominance effect would affect the expression of all ten body measurements, one reproductive trait, and nine carcass traits. It is justified to consider the dominance effects in genetic evaluation of the selected lines for those traits.

  • The purpose of this study was to investigate the effect of adolescents' need on their attitudes to aesthetic surgery and clothing. Subjects were 627 middle and high school students. In this statistical analysis, SPSS 10.0 for Windows Program was used to calculate percentage, mean, and standard deviation. Also, these data were verified by Factor analysis, t-test, One-way Anova, Duncan' multiple range, Pearson's correlation coefficient, and Multiple Regression Analysis. The results of this research were as follows: Adolescents with higher need for achievement showed negative attitudes toward the secret and risk of aesthetic surgery. On the other hand, those with higher need for dominance and exhibition were in favor of the surgery and willing to have it despite its high cost and risk. Individuality of clothing was directly affected by need for achievement and dominance. Adolescents with higher need for achievement and dominance considered individuality as one of the most important factors. And sexual attractiveness of clothing had a positive correlation with both need for dominance and exhibition. Such a fact leaded that adolescents with higher need for dominance and exhibition considered sexual attractiveness as one of the most important factors, along with individuality. As a conclusion, adolescents' need play an important role in explaining the recently observed trends among adolescents in aesthetic surgery attitude and clothing attitude.

  • In the present study, we apply the multiple cue probability learning (MCPL) paradigm to examine consumer learning from feedback in repeated trials. This paradigm is useful in investigating consumer learning, especially learning the relationships between the overall quality and attributes. With this paradigm, we can analyze what people learn from repeated trials by using the lens model, i.e., whether it is knowledge or consistency. In addition to introducing this paradigm, we aim to demonstrate that knowledge people gain from repeated trials with feedback is robust enough to weaken one of the most often examined contextual effects, the asymmetric dominance effect. The experiment consists of learning session and a choice task and stimuli are sport rafting boats with motor engines. During the learning session, the participants are shown an option with three attributes and are asked to evaluate its overall quality and type in a number between 0 and 100. Then an expert's evaluation, a number between 0 and 100, is provided as feedback. This trial is repeated fifteen times with different sets of attributes, which comprises one learning session. Depending on the conditions, the participants do one (low) or three (high) learning sessions or do not go through any learning session (no learning). After learning session, the participants then are provided with either a core or an extended choice set to make a choice to examine if learning from feedback would weaken the asymmetric dominance effect. The experiment uses a between-subjects experimental design (2 × 3; core set vs. extended set; no vs. low vs. high learning). The results show that the participants evaluate the overall qualities more accurately with learning. They learn the true trade-off rule between attributes (increase in knowledge) and become more consistent in their evaluations. Regarding the choice task, there is a significant decrease in the percentage of choosing the target option in the extended sets with learning, which clearly demonstrates that learning decreases the magnitude of the asymmetric dominance effect. However, these results are significant only when no learning condition is compared either to low or high learning condition. There is no significant result between low and high learning conditions, which may be due to fatigue or reflect the characteristics of learning curve. The present study introduces the MCPL paradigm in examining consumer learning and demonstrates that learning from feedback increases both knowledge and consistency and weakens the asymmetric dominance effect. The latter result may suggest that the previous demonstrations of the asymmetric dominance effect are somewhat exaggerated. In a single choice setting, people do not have enough information or experience about the stimuli, which may lead them to depend mostly on the contextual structure among options. In the future, more realistic stimuli and real experts' judgments can be used to increase the external validity of study results. In addition, consumers often learn through repeated choices in real consumer settings. Therefore, what consumers learn from feedback in repeated choices would be an interesting topic to investigate.

  • 본 연구는 의미적 속성을 가진 시각과 청각자극 간의 SOA(stimulus onset asynchrony)가 시청각 통합 현상에 미치는 영향을 살펴보고자 하였다. 시청각 통합 현상 중 표적을 의미하는 자극의 양상이 두 개 이상인 경우 표적에 반응이 빠르고 정확한 중복 표적 효과(redundant target effect)와 청각 자극에 비해 시각 자극에 대한 반응이 빠르고 정확한 시각 우세성 효과(visual dominance effect)를 중심으로 살펴보기 위해서 시각과 청각 단일 양상 표적 조건과 다중 양상 표적 조건을 구성하여 조건들의 반응시간과 정확률을 살펴보았다. 그 결과, 시 청각자극의 SOA가 변하더라도 중복 표적 효과는 이에 영향을 받지 않는 것으로 나타났으며, 두 자극 간의 SOA가 100ms 이상인 조건에서는 청각자극의 우세현상이 나타났다. 이러한 결과는 중복 표적 효과의 경우 두 양상자극 간의 SOA가 변하더라도 안정적으로 지속된다는 점을 시사하며, 청각자극의 경우 시각자극에 비해 약 100ms 이상의 시간적 이득조건이 마련되었을 때에 비로소 우세한 정보처리의 행동결과가 도출될 수 있음을 시사한다.

  • This study predicted consumer approach/avoidance behavior through consumer emotional experiences and examined the moderating effect of perceived surprises in the context of digital signage in store environments. A self-administered questionnaire consisted of consumer emotional experience (e.g., pleasure, arousal, and dominance), approach-avoidance behavior and perceived surprise by digital signage. A total of 278 usable responses were obtained from consumers who experienced digital signage at fashion retail stores. The findings support the Mehrabian-Russell model in the context of digital signage. Approach behavior was predicted by pleasure and arousal emotional experience, while avoidance behavior was predicted by dominance. The moderating effect of perceived surprise was also indicated in the effect of emotional experience on approach or avoidance behavior. In the high level of perceived surprise, pleasure and arousal had significant effects on approach behavior, whereas dominance had significant effect on avoidance behavior. This study discussed theoretical and managerial implications for creating emotional experiences and developing strategic store management by utilizing new digital technology within the fashion retail environments.
