Assessing personality at risk in personnel selection and development

This paper demonstrates the validity and usefulness of a count technique to screen for potential personality dysfunctioning in NEO‐PI‐R ratings obtained in selection and professional development assessments. The usefulness of this screening technique for Industrial, Work and Organizational (IWO) psychologists is demonstrated in five different samples that were administered the NEO‐PI‐R for selection or development purposes. Three additional samples served as normative data to compute FFM PD count cut‐offs that can be used for selection and career development decisions. Evidence for the construct validity of 6 out of 10 FFM PD counts was provided, and all FFM PD compound scales were significantly related to important criteria, including the final selection decision, the results of a behaviourally oriented selection interview and self‐rated work competencies. The practical utility and limitations of this count technique for personnel selection and development are discussed. Copyright © 2008 John Wiley & Sons, Ltd.     

Effects of input device and motion type on a cursor-positioning task

Many studies have investigated the performance of using nonkey-board input devices under static situations, but few have considered the effects of motion type on manipulating these input devices. In this study comparison of 12 mens' performance using four input devices (three trackballs: currently used, trackman wheel, and erectly held trackballs, as well as a touch screen) under five motion types of static, heave, roll, pitch, and random movements was conducted. The input device and motion type significantly affected movement speed and accuracy, and their interaction significantly affected the movement speed. The touch screen was the fastest but the least accurate input device. The erectly held trackball was the slowest, whereas the error rate of the currently used trackball was the lowest. Impairments of the random motion on movement time and error rate were larger than those of other motion types. Considering objective and subjective evaluations, the trackman wheel and currently used trackball were more efficient in operation than the erectly held trackball and touch screen under the motion environments.     

Predicting item exposure parameters in computerized adaptive testing

The purpose of this study is to find a formula that describes the relationship between item exposure parameters and item parameters in computerized adaptive tests by using genetic programming (GP) – a biologically inspired artificial intelligence technique. Based on the formula, item exposure parameters for new parallel item pools can be predicted without conducting additional iterative simulations. Results show that an interesting formula between item exposure parameters and item parameters in a pool can be found by using GP. The item exposure parameters predicted based on the found formula were close to those observed from the Sympson and Hetter (1985) procedure and performed well in controlling item exposure rates. Similar results were observed for the Stocking and Lewis (1998) multinomial model for item selection and the Sympson and Hetter procedure with content balancing. The proposed GP approach has provided a knowledge‐based solution for finding item exposure parameters.     

Students' perceptions of constructivist Internet learning environments by a physics virtual laboratory: the gap between ideal and reality and gender differences.

The purpose of this study was to investigate the perceptions of Internet users of a physics virtual laboratory, Demolab, in Taiwan. Learners' perceptions of Internet-based learning environments were explored and the role of gender was examined by using preferred and actual forms of a revised Constructivist Internet-based Learning Environment Survey (CILES). The students expressed a clear gap between ideal and reality, and they showed higher preferences for many features of constructivist Internet-based learning environments than for features they had actually learned in Demolab. The results further suggested that male users prefer to be involved in the process of discussion and to show critical judgments. In addition, male users indicated they enjoyed the process of negotiation and discussion with others and were able to engage in reflective thoughts while learning in Demolab. In light of these findings, male users seemed to demonstrate better adaptability to the constructivist Internet-based learning approach than female users did. Although this study indicated certain differences between males and females in their responses to Internet-based learning environments, they also shared numerous similarities. A well-established constructivist Internet-based learning environment may encourage more female learners to participate in the science community.     

Socialized reflexivity and self‐exertion: Mandala Model of Self and its role in mental health

The Mandala Model of Self (MMS) refers to the well‐functioning self leading to ultimate happiness in various cultures. This research provides the first empirical examination of the role of MMS in mental health in Confucian societies. The MMS Scale (MMSS) was developed, and its psychometric properties are described. A correlational study demonstrated that the MMSS, along with its two factors—socialized reflexivity and self‐exertion—validly measures certain mental health constructs. A quasi‐experimental study reliably distinguished persons engaged in the cultivation of the Mandala self from those who had not. Finally, a study with adolescents demonstrated that the scores of the MMSS are a better predictor of resilience than is extroversion or neuroticism. The present research provides empirical support for the theory underlying the MMS and its key contribution to mental health.     

Exploration of the prevalence and correlates of substance use among sheltered adolescents in South Korea

Substance use among sheltered adolescents is very serious in South Korea--a nation in the process of rapid industrialization and urbanization. However, few studies have investigated substance use among the adolescents which is a growing concern of the changing society of this nation. This study examined the prevalence of substance use and explored risk factors that predict substance abuse by sheltered adolescents. Through a questionnaire survey of sheltered adolescents, data on substance use and the risk factors were collected. The sample of the adolescents included 44 (33.3%) males and 88 (67.2%) females; their mean age was 15.8 years (SD = 1.62). The results of a logistic regression analysis showed that alcohol expectancy, physical abuse, and peer pressure were all statistically significantly associated with substance abuse. Findings on the critical issues are expected to lead to the development of urgently needed prevention programs for the high-risk adolescents in South Korea.     

Unconscious processing embedded in conscious processing: evidence from gaze time on Chinese sentence reading

The current study aims to separate conscious and unconscious behaviors by employing both online and offline measures while the participants were consciously performing a task. Using an eye-movement tracking paradigm, we observed participants' response patterns for distinguishing within-word-boundary and across-word-boundary reverse errors while reading Chinese sentences (also known as the "word inferiority effect"). The results showed that when the participants consciously detected errors, their gaze time for target words associated with across-word-boundary reverse errors was significantly longer than that for targets words associated with within-word-boundary reverse errors. Surprisingly, the same gaze time pattern was found even when the readers were not consciously aware of the reverse errors. The results were statistically robust, providing converging evidence for the feasibility of our experimental paradigm in decoupling offline behaviors and the online, automatic, and unconscious aspects of cognitive processing in reading.     

LTP induction modifies functional relationship among hippocampal neurons

To obtain evidence linking long-term potentiation (LTP) and memory, we examined whether LTP induction modifies functional relationship among neurons in the rat hippocampus. In contrast to neurons in low-frequency stimulated or AP5-treated slices, LTP induction altered 'functional connectivity,' as defined by the degree of synchronous firing, among simultaneously recorded neurons in the CA3 region. Interestingly, functional connectivity changed bidirectionally so that the total sum of functional connectivity remained constant. These results demonstrate LTP-induced changes in neuronal functional connectivity and suggest the existence of a normalization mechanism for the total sum of functional connectivity.     

Ten-year-old girls' and boys' body composition and peer victimization experiences: prospective associations with body satisfaction

This study examined prospective associations between 10-year-olds’ weight and height, their perception of shape and stature, frequent experiences of peer victimization, and different aspects of body esteem at age 13. Participants were 474 girls and 400 boys participating in a two-wave longitudinal questionnaire study. Main results were that whereas actually being heavier built at age 10 was associated with girls’ increments in body dissatisfaction, the mere perception of being too heavy was associated with boys’ poorer body satisfaction. Also, boys who believed that they were too short were more dissatisfied at follow-up. Whereas frequent peer victimization had long-term associations with girls’ weight-esteem, teasing targeted towards appearance was associated with boys’ more negative beliefs about what others think about their appearance. Finally, participants had become significantly more dissatisfied at age 13, suggesting that this is a time in life when both girls and boys risk becoming increasingly critical towards their appearance.     

The psychotherapy adaptation and modification framework: application to Asian Americans

Although effective treatments for many mental disorders have been developed, little research has been conducted to determine whether these interventions are effective in treating those from diverse backgrounds. Recent reports have suggested that ethnic minorities are less likely to receive quality health services and that they evidence worse treatment outcomes when compared with other groups. To improve care for those from diverse backgrounds, Western-developed psychotherapies may need to be culturally modified or adapted to become more effective in treating ethnic minorities. This article addresses the need for adapting psychotherapy and provides a conceptual framework for making such modifications. The psychotherapy adaptation and modification framework model is applied to recent Asian American immigrants as an illustrative example. However, it may also serve as a point of departure to adapt therapies for other ethnocultural groups.
