Experimental results of affective valence and arousal to avatar's facial expressions.

The objectives of this study were to propose a method of presenting dynamic facial expressions to experimental subjects, in order to investigate human perception of avatar's facial expressions of different levels of emotional intensity. The investigation concerned how perception varies according to the strength of facial expression, as well as according to an avatar's gender. To accomplish these goals, we generated a male and a female virtual avatar with five levels of intensity of happiness and anger using a morphing technique. We then recruited 16 normal healthy subjects and measured each subject's emotional reaction by scoring affective arousal and valence after showing them the avatar's face. Through this study, we were able to investigate human perceptual characteristics evoked by male and female avatars' graduated facial expressions of happiness and anger. In addition, we were able to identify that a virtual avatar's facial expression could affect human emotion in different ways according to the avatar's gender and the intensity of its facial expressions. However, we could also see that virtual faces have some limitations because they are not real, so subjects recognized the expressions well, but were not influenced to the same extent. Although a virtual avatar has some limitations in conveying its emotion using facial expressions, this study is significant in that it shows that a new potential exists to use or manipulate emotional intensity by controlling a virtual avatar's facial expression linearly using a morphing technique. Therefore, it is predicted that this technique may be used for assessing emotional characteristics of humans, and may be of particular benefit for work with people with emotional disorders through a presentation of dynamic expression of various emotional intensities.     

Differences in brain information transmission between gifted and normal children during scientific hypothesis generation

The purpose of the present study was to investigate differences in neural information transmission between gifted and normal children involved in scientific hypothesis generation. To investigate changes in the amount of information transmission, the children's averaged-cross mutual information (A-CMI) of EEGs was estimated during their generation of scientific hypotheses. We recorded EEG from 25 gifted and 25 age-matched normal children using 16 electrodes on each subject's scalp. To generate hypotheses, the children were asked to observe 20 "quail eggs" that gave rise to questions. After observation, they were asked to generate a scientific hypothesis--a tentative causal explanation for the questions evoked. The results of this study revealed several distinguishing brain activities between gifted and normal children during hypothesis generation. In contrast to normal children, gifted children showed increased A-CMI values between the left temporal and central, between the left temporal and parietal, and between the left central and parietal locations while generating a hypothesis. These results suggested that gifted children more efficiently distribute the cognitive resources essential to cope with hypothesis generation.     

The Development of Proportional Reasoning: Effect of Continuous Versus Discrete Quantities

This study examines the development of children's ability to reason about proportions that involve either discrete entities or continuous amounts. Six-, 8- and 10-year olds were presented with a proportional reasoning task in the context of a game involving probability. Although all age groups failed when proportions involved discrete quantities, even the youngest age group showed some success when proportions involved continuous quantities. These findings indicate that quantity type strongly affects children's ability to make judgments of proportion. Children's greater success in judging proportions involving continuous quantities appears to be related to their use of different strategies in the presence of countable versus noncountable entities. In two discrete conditions, children—particularly 8- and 10-year-olds—adopted an erroneous counting strategy, considering the number of target elements but not the relation between target and nontarget elements, either in terms of number or amount. In contrast, in the continuous condition, when it was not possible to count, children may have relied on an early developing ability to code the relative amounts of target and nontarget regions.     

Partner effects of Mexican cultural values: the couple and parenting relationships

In this investigation, the authors explored the impact of individuals' cultural values on their partners' relationship adjustment and perceptions of their parenting relationship. The authors examined Mexican cultural values of simpatía (i.e., harmonious interpersonal relationships) and respeto (i.e., respect for authority figures) using a sample of 50 Mexican-origin couples in southern Arizona. Congruent with their hypotheses, results supported the proposition that fathers' simpatía is positively associated with both relationship adjustment and the parenting relationship as reported by mothers, whereas fathers' respeto is negatively associated with both relationship adjustment and the parenting relationship as reported by mothers. However, the authors found little evidence of a contribution of mothers' cultural values to fathers' perceptions of either relationship adjustment or the parenting relationship. They interpret these findings to suggest that mothers' relationship adjustment and parenting relationship are more sensitive to and dependent on fathers' degree of traditional cultural values among Mexican-origin families.     

Preschoolers’ Emotional Understanding and Psychosocial Adjustment in Korea: The Moderating Effect of Maternal Attitude towards Emotional Expressiveness

The purpose of the present study was to examine the role of maternal attitude towards children’s emotional expressiveness in Korean preschoolers’ emotional understanding and psychosocial adjustment. Preschoolers (N?=?70) participated in an emotional understanding task comprised of identifying cartoon character’s emotional reaction to particular emotion-eliciting situations. Maternal attitude towards children’s emotional expressiveness, as well as teachers’ rating of children’s behavior problems and social competence were measured. Children’s emotional understanding was negatively correlated with teacher-reported behavior problems and positively associated with social competence. In line with recent research on the socialization of emotional expressiveness, controlling maternal attitude towards children’s positive emotional expressiveness was negatively correlated with teacher-reported behavior problems. Conversely, mothers’ accepting attitude towards children’s negative emotional expressiveness was also negatively correlated with behavior problems. Finally, maternal attitude toward children’s positive emotional expressiveness moderated the relationship between emotional understanding ability and behavior problems and social competence. Such findings suggest that maternal attitude, particularly attitude regarding specific type of emotional expressiveness, is one of the key factors that may predict preschooler’s psychosocial outcomes.     

“I” value competence but “we” value social competence: The moderating role of voters' individualistic and collectivistic orientation in political elections

This investigation distinguishes interpersonally oriented social competence from intrapersonally oriented competence. It examines the influence of voters' individualism and collectivism orientation in affecting the roles of these two dimensions in predicting electoral outcomes. Participants made judgments of personality traits based on inferences from faces of political candidates in the U.S. and Taiwan. Two social outcomes were examined: actual election results and voting support of the participants. With respect to actual electoral success, perceived competence is more important for the candidates in the U.S. than for those in Taiwan, whereas perceived social competence is more important for the candidates in Taiwan than for those in the U.S. With respect to subjective voting support, within cultural findings mirror those found cross-culturally. Competence is valued more among voters who are more individualistic, and social competence is valued more among voters who are more collectivistic. These results highlight important omissions in the social perception/judgment literature.
