The cognitive loci of the display and task-relevant set size effects on distractor interference: Evidence from a dual-task paradigm

The congruency effect of a task-irrelevant distractor has been found to be modulated by task-relevant set size and display set size. The present study used a psychological refractory period (PRP) paradigm to examine the cognitive loci of the display set size effect (dilution effect) and the task-relevant set size effect (perceptual load effect) on distractor interference. A tone discrimination task (Task 1), in which a response was made to the pitch of the target tone, was followed by a letter discrimination task (Task 2) in which different types of visual target display were used. In Experiment 1, in which display set size was manipulated to examine the nature of the display set size effect on distractor interference in Task 2, the modulation of the congruency effect by display set size was observed at both short and long stimulus-onset asynchronies (SOAs), indicating that the display set size effect occurred after the target was selected for processing in the focused attention stage. In Experiment 2, in which task-relevant set size was manipulated to examine the nature of the task-relevant set size effect on distractor interference in Task 2, the effects of task-relevant set size increased with SOA, suggesting that the target selection efficiency in the preattentive stage was impaired with increasing task-relevant set size. These results suggest that display set size and task-relevant set size modulate distractor processing in different ways.     

Can an organization's philanthropic donations encourage consumers to give? The roles of gratitude and boundary conditions

This study examines whether an organization's charitable donation will prompt consumers who closely identify with the organization to give to the charity as well. We posit that identifying with a benefactor will enhance the perception that consumers are involved in the donation process, which evokes grateful feelings. We also predict that the amount of the organization's donation will positively moderate the influence of organization identification on charity‐evoked feelings of gratitude, while attitude toward the organization's charity will positively moderate the gratitude–donation relationship. In Study 1, we show how gratitude arises in the context of corporate social responsibility by demonstrating the mediating role of perceived donation contribution in the relationship between organization identification and gratitude. In Study 2, we demonstrate that organization identification has a significant indirect effect on donation intention through gratitude. Multigroup analyses show that the identification–gratitude link is more salient when the organization commits to donating a larger amount of money to a charity. Furthermore, the impact of gratitude on donation intent is significantly stronger for individuals who hold a favorable attitude toward the organization's corporate social responsibility activity. Our findings indicate that an organization's charitable giving also encourages consumers to give to the community via vicariously felt gratitude. Copyright © 2016 John Wiley & Sons, Ltd.     

Computation of mean size is based on perceived size

The present study investigated whether computation of mean object size was based on perceived or physical size. The Ebbinghaus illusion was used to make the perceived size of a circle different from its physical size. Four Ebbinghaus configurations were presented either simultaneously (Experiment 1) or sequentially (Experiment 2) to each visual field, and participants were instructed to attend only to the central circles of each configuration. Participants’ judgments of mean central circle size were influenced by the Ebbinghaus illusion. In addition, the Ebbinghaus illusion influenced the coding of individual size rather than the averaging. These results suggest that perceived rather than physical size was used in computing the mean size.     

From hierarchy to rivalry: Asian candidate evaluation in changing racial contexts

Existing studies on candidate evaluation have posited that racial cues would invoke negative attitudes toward outgroups, thus lowering support for minority candidates. However, recent studies have found that even implicit racial cues show no negative effect but actually work positively in favor of the minority candidates. In this study, I explore this puzzle by setting up a survey experiment that pairs an Asian candidate against competitors with varying racial backgrounds. Consistent with the existing evidence, I found that White voters tend to support an Asian candidate to a greater degree than a co‐ethnic, White competitor. However, departing from the previous studies that have explained this tendency as a reward for model minority, I argue that such a pattern is associated with reaffirming Whites’ ingroup identity in a racial hierarchy by compensating minorities. When the apparent racial hierarchy—White versus non‐White—is replaced with a minority‐only context, Whites no longer need to favor an Asian candidate and divide their support more evenly to the two minority candidates. I further show that this tendency is moderated by the intensity of their ingroup attitudes.     

A job-seeking competency model for North Korean defectors who are college students in South Korea

The purpose of this study was to develop a job-seeking competency model for North Korean defectors (NKDs) who are college students in South Korea. This study adopted the Delphi method with a panel of 17 experts, comprising of NKDs who secured their jobs successfully and South Korean field experts who have hired NKDs or assisted them with their employment. Through three Delphi rounds, 18 job-seeking competencies were identified with the definition, behavioural indicators, and competency significance. In addition, the preliminary utility of the competency model was examined. Implications of the study results and future directions for enhancing the validity and utility of the competency model are discussed.     

counselors' collective self‐esteem mediates job dissatisfaction and client relationships

Given the central role of professional identity (i.e., collective self‐esteem in this study), the authors examined whether collective self‐esteem mediated or moderated relations between job dissatisfaction and client relationships in a sample of 132 professional counselors in the United States. Results indicated that collective self‐esteem partially mediated the relationship between job dissatisfaction and client relationships. Furthermore, job dissatisfaction was negatively related to greater levels of private collective self‐esteem, and greater private collective self‐esteem was positively related to better client relationships.     

Assessing Item Fit for Unidimensional Item Response Theory Models Using Residuals from Estimated Item Response Functions

Residual analysis (e.g. Hambleton & Swaminathan, Item response theory: principles and applications, Kluwer Academic, Boston, 1985; Hambleton, Swaminathan, & Rogers, Fundamentals of item response theory, Sage, Newbury Park, 1991) is a popular method to assess fit of item response theory (IRT) models. We suggest a form of residual analysis that may be applied to assess item fit for unidimensional IRT models. The residual analysis consists of a comparison of the maximum-likelihood estimate of the item characteristic curve with an alternative ratio estimate of the item characteristic curve. The large sample distribution of the residual is proved to be standardized normal when the IRT model fits the data. We compare the performance of our suggested residual to the standardized residual of Hambleton et al. (Fundamentals of item response theory, Sage, Newbury Park, 1991) in a detailed simulation study. We then calculate our suggested residuals using data from an operational test. The residuals appear to be useful in assessing the item fit for unidimensional IRT models.     

Social identity,attribution, and emotion: Comparisons of Americans,Korean Americans,and Koreans

The social identity of another person, in addition to the social identity of self, can be an important factor affecting the types of attribution judgments and emotions that individuals indicate for the other person. In April 2007, the perpetrator of the shooting incident on the Virginia Tech University campus was identified as a person who emigrated to the USA from Korea at a young age. The current study compared non‐Korean Americans, Korean Americans, Koreans in the USA, and Koreans in Korea in terms of their attributions and emotions concerning the perpetrator and the shooting incident. Participants were asked to indicate (1) the extent to which they attributed the cause of the incident to either American society or the perpetrator, (2) their emotions (e.g., upset), and (3) the extent to which they categorized the perpetrator as an American, a Korean American, or a Korean. The results indicated that non‐Korean Americans were most likely to attribute the cause of the incident to the perpetrator as opposed to American society. Non‐Korean Americans, Korean Americans, and Koreans in the United States had more negative emotions (e.g., unhappy, sad, and upset) about the incident than Koreans in Korea did. The results also indicated that individuals differed in their attributions and emotions depending on how they categorized the perpetrator. For example, categorizing the perpetrator as being a Korean was positively related to Americans’ tendency to hold the perpetrator responsible, while categorizing the perpetrator as being an American was negatively related to the tendency to hold the perpetrator responsible among Koreans in Korea. The findings may imply that social identity theory, intergroup emotion theory, and cultural orientations (e.g., individualism and collectivism) can provide insights into people's reactions to a tragic incident.     

Using online social media,Facebook, in screening for major depressive disorder among college students

This study explored the feasibility of using Internet social networking media in an online program for Major Depressive Disorder (MDD) screening and psychoeducation targeting college students. A Facebook advertisement targeted students at five colleges in the United States to complete a mental health research survey that screened for MDD using the Patient Health Questionnaire-9 (PHQ-9). Students who screened positive for MDD were offered an eightweek follow-up survey. Of the 259 students who consented to participate in the study, 26.7% screened positive for MDD, while only 14.2% were receiving treatment. The use of Facebook to advertise for online screening for MDD required very little start-up time, and the average cost was $11.45 per subject recruited. It is feasible to use online, commercially available social networking media such as Facebook for online screening for MDD among college students. However, conducting online screening and offering treatment resources alone did not increase treatment rate in this population.     

The Creativity Crisis: The Decrease in Creative Thinking Scores on the Torrance Tests of Creative Thinking

The Torrance Tests of Creative Thinking (TTCT) was developed in 1966 and renormed five times: in 1974, 1984, 1990, 1998, and 2008. The total sample for all six normative samples included 272,599 kindergarten through 12th grade students and adults. Analysis of the normative data showed that creative thinking scores remained static or decreased, starting at sixth grade. Results also indicated that since 1990, even as IQ scores have risen, creative thinking scores have significantly decreased. The decrease for kindergartners through third graders was the most significant.
