Updating objects in visual short-term memory is feature selective

The purpose of this study was to examine whether the process of updating information in visual short-term memory (VSTM) is object based. We investigated whether modifying the memory of one feature of an object would automatically promote refreshing the memory of all of its other features. The results showed that the facilitative effect of updating was specific to the updated feature of an object and did not spread to its nonupdated features. This feature-selective effect suggests that updating VSTM is not object based (Experiment 1), even though storage was object based (Experiment 2). Control experiments ruled out strategy-based (Experiment 3) and stimulus-related (Experiments 4–6) accounts. Feature-selective updating may indicate that the mechanism used to modify the contents of memory may have a different basis than that used to encode or store information in memory.     

Pursuit of comfort and pursuit of harmony: culture, relationships, and social support seeking

This research examined whether people from collectivistic cultures are less likely to seek social support than are people from individualistic cultures because they are more cautious about potentially disturbing their social network. Study 1 found that Asian Americans from a more collectivistic culture sought social support less and found support seeking to be less effective than European Americans from a more individualistic culture. Study 2 found that European Americans' willingness to seek support was unaffected by relationship priming, whereas Asian Americans were willing to seek support less when the relationship primed was closer to the self. Study 3 replicated the results of Study 2 and found that the tendency to seek support and expect social support to be helpful as related to concerns about relationships. These findings underscore the importance of culturally divergent relationship patterns in understanding social support transactions.     

Investigation of the effect of group counselling based on schema therapy on academic expectation stress in high school students

This research is a preliminary evaluation study to determine whether group counselling based on schema therapy has an effect on academic expectation stress in high school students. In this study, a 2 × 3 split-plot design was used. The Academic Expectation Stress Inventory was applied for data collection purposes. The effect of group counselling based on schema therapy on academic expectation stress was tested using a two-factor ANOVA for mixed measurements. As a result of the analysis, the intervention*time effect was found to be significant with regard to academic expectation stress. The findings obtained in the study reveal that group counselling based on schema therapy creates a significant decrease in adolescents' academic expectation stress level, and this decline continues, as shown in the follow-up test. As a result, it can be said that the group counselling programme based on schema therapy, which was developed as a preliminary evaluation study, has the potential to reduce the academic expectation stress level of high school students.     

Manual discrimination and identification of length by the finger-span method

Experiments were conducted on length resolution for objects held between the thumb and fore-finger. The just noticeable difference in length measured in discrimination experiments is roughly 1 mm for reference lengths of 10 to 20 mm. It increases monotonically with reference length but violates Weber's law. Also, it decreases when the subject is permitted to maintain a constant finger span between trials; however, it tends to increase when the nondominant hand is used. As would be expected from studies of other stimulus dimensions in other sense modalities, resolution is considerably poorer in identification experiments than in discrimination experiments. For stimulus sets that cover a broad range (90 mm), the total information transfer is roughly 2 bits; for those that cover a relatively small range (18 mm), it is roughly 1 bit. The data are analyzed and interpreted using analysis techniques and models that have been used previously in studies of audition (e.g., Durlach & Braida, 1969).     

Analysis of effects of driver/vehicle characteristics on acceleration noise using GPS-equipped vehicles

Researchers have used acceleration noise, defined by the standard deviation of accelerations of a vehicle, as an attempt to measure the quality of traffic flow. As a potential indicator of traffic flow quality, acceleration noise has been considered to be capable of reflecting vehicle/driver–roadway–traffic interactions within a traffic stream. However, this proposition, in particular for the driver/vehicle, has seldom been investigated, mainly due to the difficulty of data collection. This paper reports the results of an analysis of the effects of driver/vehicle characteristics on acceleration noise using global positioning system (GPS)-equipped instrumented vehicle data obtained from four freeway segments. In the analysis, speed models were developed and compared with acceleration noise models. In addition, the effects were investigated by traffic condition levels defined by the density-based level of service.     

Voice and Culture: A Prospect Theory Approach

The present study examines the congruence of individuals' minimum preferred amounts of voice with the prospect theory value function across nine countries. Accounting for previously ignored minimum preferred amounts of voice and actual voice amounts integral to testing the steepness of gain and loss functions explicated in prospect theory, we use curve fitting to show that ratings of procedural justice fit prospect theory's value function specifically. Further, we investigate the form of this function across nine countries that range in power distance. Results suggest that the form of the value function is congruent with prospect theory, showing an S‐shaped curve that is steeper in the loss than in the gain domain. Further, this pattern is similar across countries. Theoretical and practical implications of these results for both decision making and organizational justice are discussed.

Exploring the Ethical Aspects of Leadership: From a Korean Perspective

Theories of ethical leadership provide important insights about the effect of leader’s ethics on the relationship between leaders and followers. However, there is an increasing demand for addressing key constructs that enhance the capacity to explain theoretical aspects of ethical leadership. The purpose of this study is to expand the theoretical framework of ethical leadership based on Korean traditional leadership by focusing on personal cultivation, morality, and social responsibility. Using a framework of intrapersonal process as leadership and core value and competence as components of leadership, this study examines the ethical aspects of Korean traditional leadership and provides the implications to further develop the theory of ethical leadership. It is found that ethical integrity ensued from sugi (self-cultivation) is an essential precondition to develop leadership, and the core value of ethical leadership includes Zhixin-Chijing (cultivation of the mind and internal piety) and the competence consists of both Ipzhi (setting a solid self-vision/establishing goal) and Silsim (practical mind, grasp changes in reality with a sound mind) in Korean traditional leadership that contributes to expanding the theoretical understanding of ethical leadership. Implications for future research in the area of ethical leadership are discussed.     

Determinants of consumer attitude toward corporate sponsors: A comparison between a profit and nonprofit sport event sponsorship

The purposes of the present study were to identify key attributes of sponsors that positively influence consumers' attitude formation and to examine the moderator role of sport event types (nonprofit vs. profit). Based on the theories of range and selective attention, we hypothesized that consumers weigh differently on particular sponsorship attributes depending on event type (i.e., profit vs. nonprofit) in constructing their attitude. The study utilized multi‐group structural equation modeling on data collected by questionnaire survey from a total of 505 spectators of college sport event (n = 303) and FIFA World Cup (n = 202). Results of structural equation modeling test indicate that prominence of sponsors is an important predictor of consumer attitude in both events, while sincerity of sponsors was found to be important in local and amateur college sport event sponsorship. From a theoretical perspective, the current study sheds light on sponsorship study, particularly the importance of examining sponsor characteristics in predicting consumer attitude and the event type as a moderating variable. A key practical implication is that sport managers should carefully examine consumers' perceptions toward sponsor characteristics in making their event sponsorship decisions.
