Acting Superior But Actually Inferior?: Correlates and Consequences of Workplace Arrogance

Accounts of arrogant employees abound, yet there is little systematic research on arrogance within organizations. In response to this oversight, this article presents the findings from four studies. In Studies 1 and 2, the authors developed the Workplace Arrogance Scale and found support for its convergent and discriminant validity. In Study 3, the Workplace Arrogance Scale was included as part of a 360-degree performance feedback survey. Results revealed that there was satisfactory agreement between self- and other-ratings of arrogance. The authors also found that arrogance was negatively related to self- and other-rated task performance. Findings from Study 4 suggested that arrogance is negatively related to cognitive ability and self-esteem. The authors conclude by discussing the theoretical and practical implications of these findings.     

Development of an Individualism-Collectivism Scale revisited: a Korean sample

A 13-item Individualism-Collectivism scale comprising source of identity, goal priority, mode of social relation, and norm acceptance is presented. A validation of this scale was conducted using a survey of 773 Korean employees. An exploratory factor analysis and a second-order confirmatory factor analysis supported the measure as having theoretical face validity and acceptable internal consistency reliability. Among the four facets, goal priority most strongly predicted the general Individualism-Collectivism latent factor.     

Visual spatial skill: a consequence of learning to read?

Does learning to read influence one’s visual skill? In Study 1, kindergartners from Hong Kong, Korea, Israel, and Spain were tested on word reading and a task of visual spatial skill. Chinese and Korean kindergartners significantly outperformed Israeli and Spanish readers on the visual task. Moreover, in all cultures except Korea, good readers scored significantly higher on the visual task than did less good readers. In Study 2, we followed 215 Hong Kong Chinese kindergartners across 1 year, with word reading and visual skills tested twice. In this study, word reading at Time 1 by itself predicted 13% of unique variance in visual skill at Time 2. Together, these results underscore the potential importance of the process of learning to read for shaping one’s visual spatial skill development.     

How does a child solve 7 + 8? Decoding brain activity patterns associated with counting and retrieval strategies

Cognitive development and learning are characterized by diminished reliance on effortful procedures and increased use of memory-based problem solving. Here we identify the neural correlates of this strategy shift in 7-9-year-old children at an important developmental period for arithmetic skill acquisition. Univariate and multivariate approaches were used to contrast brain responses between two groups of children who relied primarily on either retrieval or procedural counting strategies. Children who used retrieval strategies showed greater responses in the left ventrolateral prefrontal cortex; notably, this was the only brain region which showed univariate differences in signal intensity between the two groups. In contrast, multivariate analysis revealed distinct multivoxel activity patterns in bilateral hippocampus, posterior parietal cortex and left ventrolateral prefrontal cortex regions between the two groups. These results demonstrate that retrieval and counting strategies during early learning are characterized by distinct patterns of activity in a distributed network of brain regions involved in arithmetic problem solving and controlled retrieval of arithmetic facts. Our findings suggest that the reorganization and refinement of neural activity patterns in multiple brain regions plays a dominant role in the transition to memory-based arithmetic problem solving. Our findings further demonstrate how multivariate approaches can provide novel insights into fine-scale developmental changes in the brain. More generally, our study illustrates how brain imaging and developmental research can be integrated to investigate fundamental aspects of neurocognitive development.     

Relationships of suicide ideation with cause-specific mortality in a longitudinal study of South Koreans

Using 7-year mortality follow-up data (n = 341) from the 1998 National Health and Nutrition Examination Surveys of South Korean individuals (N = 5,414), the authors found that survey participants with suicide ideation were at increased risk of suicide mortality during the follow-up period compared with those without suicide ideation. The cause-specific analyses showed that, in men, suicide ideation was significantly associated with mortality due to cardiovascular disease, external causes, and other causes. However, there was no significant association between suicide ideation and cause-specific mortality in women. The relationship between suicide ideation and cause-specific mortality in men was not fully explained by baseline health status, socioeconomic status, health behavior, or psychosocial factors.     

Differential Item Functioning on Antisocial Behavior Scale Items for Adolescents and Young Adults from Single-Parent and Two-Parent Families

We investigated measurement equivalence in two antisocial behavior scales (i.e., one scale for adolescents and a second scale for young adults) by examining differential item functioning (DIF) for respondents from single-parent (n = 109) and two-parent families (n = 447). Even though one item in the scale for adolescents and two items in the scale for young adults showed significant DIF, the two scales exhibited non-significant differential test functioning (DTF). Both uniform and nonuniform DIF were investigated and examples of each type were identified. Specifically, uniform DIF was exhibited in the adolescent scale whereas nonuniform DIF was shown in the young adult scale. Implications of DIF results for assessment of antisocial behavior, along with strengths and limitations of the study, are discussed.     

Neurofeedback training with virtual reality for inattention and impulsiveness.

In this research, the effectiveness of neurofeedback, along with virtual reality (VR), in reducing the level of inattention and impulsiveness was investigated. Twenty-eight male participants, aged 14-18, with social problems, took part in this study. They were separated into three groups: a control group, a VR group, and a non-VR group. The VR and non-VR groups underwent eight sessions of neurofeedback training over 2 weeks, while the control group just waited during the same period. The VR group used a head-mounted display (HMD) and a head tracker, which let them look around the virtual world. Conversely, the non-VR group used only a computer monitor with a fixed viewpoint. All participants performed a continuous performance task (CPT) before and after the complete training session. The results showed that both the VR and non-VR groups achieved better scores in the CPT after the training session, while the control group showed no significant difference. Compared with the other groups, the VR group presented a tendency to get better results, suggesting that immersive VR is applicable to neurofeedback for the rehabilitation of inattention and impulsiveness.     

Influences of multiple spatial stimulus and response codes on orthogonal stimulus—response compatibility

When up-down stimuli are mapped to left-right responses, an up-right/down-left mapping advantage is found that is modified by response eccentricity and hand posture. These effects can be attributed to correspondence of asymmetric stimulus and response codes formed relative to multiple reference frames. We examined the influence of stimulus-set location on these orthogonal stimulus-response compatibility (SRC) effects. In Experiment 1, the stimulus set appeared in the upper or lower display positions. A spatial code for stimulus-set location was formed, producing Simon-type response eccentricity and hand posture effects, but this code had no influence on the coding of the relevant stimuli. In Experiment 2, the stimulus set appeared in the left, center, or right positions relative to the response location, which also varied, to dissociate the effects of response location, relative to the stimulus display and body midline. The former factor influenced the orthogonal SRC effect for both unimanual switch movements and bimanual keypresses, and the latter factor influenced the effect for only unimanual switch movements. Stimulus-set location causes orthogonal Simon-type effects when varied along the stimulus dimension and provides a referent for response coding when varied along the response dimension.     

An interest‐based intervention package to increase peer social interaction in young children with autism spectrum disorder

The literature suggests that children with autism spectrum disorder (ASD) educated in inclusive settings generally do not interact with typically developing classmates during social activities. This study assessed whether an intervention package consisting of interest‐based structured play activities involving adult instruction, modeling, and response to child questions would result in an increase in social interaction with typically developing peers. A multiple baseline design across four participants with an embedded reversal was used to demonstrate the effects of the intervention on social interaction during structured play sessions. Initiations, responses, and interactive play increased for all participants. Generalization to novel peers was observed, and treatment gains were maintained during 6‐week follow‐up sessions. Recommendations for practitioners working with children with ASD in inclusive settings and potential areas of future research are discussed.     

Pilot study of hormone replacement therapy and menopausal symptoms, depression, and quality of life in Korean climacteric women

This cross-sectional survey compared scores on the Menopausal Symptoms Index, Depression, and the Quality of Life for 65 Korean climacteric women receiving regular hormone replacement therapy (M age=52.8 yr., SD=6.3) and 70 Korean climacteric patients not receiving such therapy (M age =51.6 yr., SD=7.1). Depression scores were positively correlated with the Menopausal Symptoms Index in both groups (r = .58 in the Therapy group and r = .50 in the Control group) and negatively correlated with scores for Quality of Life (r = -.48 in the Therapy group and r = -.68 in the Control group). Scores on the Menopausal Symptoms Index were negatively correlated with ratings of Quality of Life in both groups (r = -.53 in the Therapy group and r = -.45 in the Control group). These results suggest that hormone replacement therapy is associated with reduced Depression scores and higher Quality of Life scores in this sample of Korean climacteric women.
