Neurofeedback Training Reduces Frontal Midline Theta and Improves Putting Performance in Expert Golfers

A single-subject design was used to examine the influence of one session of neurofeedback training (NFT) on reducing frontal midline theta (Fmθ) amplitude and enhancing golf putting performance. Posttraining, three highly skilled golfers improved in putting score or score stability. Although the Fmθ amplitude during the pre-putt period inconsistently decreased across participants, all golfers exhibited lower Fmθ amplitude during the resting condition following NFT, suggesting that the tonic reduction of Fmθ may play a role in subsequent performance improvement. Overall, these results indicate that a short session of NFT may be an effective method of performance enhancement in some sports.     

Aerobic Fitness Is Associated With Cognitive Control Strategy in Preadolescent Children

The authors used a conditional accuracy function (CAF) method to compute the mean accuracy of multiple reaction time ranges, to investigate the association between aerobic fitness and the utilization of cognitive control strategy during preadolescence. Thirty-eight higher- and lower-fit children were grouped according to their cardiorespiratory capacity (VO_2max) and completed a modified flanker task. Seventeen young adults were recruited as a reference group of maturation. The results showed that higher-fit children exhibited an adult-like performance pattern, and demonstrated increased overall response accuracy compared to lower-fit children, with a disproportionally larger increase in individual responses when the time allowed for discriminative processing was constrained. These findings suggest that aerobic fitness is associated with enhanced cognitive control and development of a more proactive control strategy during flanker task in preadolescent children.     

Work stress, Chinese work values, and work well-being in the Greater China

Work values influence our attitudes and behavior at work, but they have rarely been explored in the context of work stress. The aim of this research was thus to test direct and moderating effects of Chinese work values (CWV) on relationships between work stressors and work well-being among employees in the Greater China region. A self-administered survey was conducted to collect data from three major cities in the region, namely Beijing, Hong Kong, and Taipei (N = 380). Work stressors were negatively related to work well-being, whereas CWV were positively related to work well-being. In addition, CWV also demonstrated moderating effects in some of the stressor-job satisfaction relationships.     

Transformational Leadership and Athlete Satisfaction: The Mediating Role of Coaching Competency

Drawing on social cognitive theory, we examine the relationship between coaches’ transformational leadership and athletes’ evaluations of coaches’ coaching competency. We also investigate how coaching competency can mediate the positive effect of coaches’ transformational leadership on athletes’ satisfaction. Using path analysis with bootstrapping techniques, we analyzed 397 competitive volleyball players to test our research model. Our results revealed that (a) coaches’ transformational leadership has a positive effect on coaching competency, and (b) coaching competency mediates the positive effect of coaches’ transformational leadership on athletes’ satisfaction. Implications for coach education and sport psychology in terms of theory and research are discussed.     

Fostering Change-Oriented Behaviors: A Broaden-and-Build Model

Purpose

The purpose of this study was to develop and test a broaden-and-build model relating LMX to employees’ change-oriented behaviors (creative performance and taking charge) through the mediators of positive affect and psychological capital.

Design/Methodology/Approach

Time-lagged, two-source data were collected from 248 participants and 40 direct leaders, which composed a heterogeneous sample of professional jobs from a three-wave data collection strategy. Mplus was employed to test the proposed hypotheses.

Findings

We found that LMX predicts employees’ change-oriented behaviors through two sequential paths: (a) the positive affect mediates the relationship between LMX and employee psychological capital, and (b) psychological capital mediates the relationship between positive affect and employees’ creative performance and taking charge. Our results provide a logical explanation of the ‘broadening’ and ‘building’ mechanisms through which LMX enhances employees’ change-oriented behaviors.

Implications

This study specifically suggests affective and psychological mechanisms by promoting the broadening and building phases that facilitate the transformation of individual perceptions of LMX, positive affect, and psychological capital in explaining employees’ creative performance and taking charge.

Originality/Value

This study develops a broaden-and-build model of change-oriented behaviors and contributes to research on proactive behaviors in the context of leader-member relationships.

     

A National Survey of Genetic Counselors’ Personal Values

Personal values are motivational sources for an individual’s actions [Hitlin and Piliavin (Annual Review of Sociology 30:359–393, 2004)]. Genetic counselors’ values may influence their behaviors in clinical practice, but a profile of their personal values has not been identified empirically. In this study, 292 genetic counselors completed the Schwartz Universal Values Questionnaire (SUVQ; Schwartz, S. H. (1992). Universals in the content and structure of values: Theoretical advances and empirical tests in 20 countries. In M. Zanna (Ed.), Advances in experimental social psychology (pp. 1–65). Boston, MA: Academic.), a widely used measure of value types, and provided information about their demographic characteristics. Results indicate that respondents highly valued benevolence, self-direction, achievement, and universalism indicating a strong pattern of concern for the welfare of others. They placed considerably less value on stimulation, tradition, and power, which reflect personal interests. Respondents who reported practicing a religion scored significantly lower on stimulation and hedonism and higher on tradition and spirituality than those not practicing; married respondents and parents scored significantly lower on stimulation and achievement; and males scored higher on power than females. The value types are described, and training and research recommendations are provided.     

Mattering: Empirical Validation of a Social-Psychological Concept

Mattering is the extent to which we make a difference in the world around us. People matter simply because: others attend to them (awareness), invest themselves in them (importance), or look to them for resources (reliance). We construct and validate a mattering index, using confirmatory factor analysis. We establish the discriminant validity of the mattering index, using self-consciousness, self-esteem, self-monitoring, alienation, and perceived social support. Finally, we discuss the potential importance of mattering as a dimension of the self-concept.     

Avoidance temperament and social-evaluative threat in college students' math performance: a mediation model of math and test anxiety

Background and Objectives: Standardized testing has become a common form of student evaluation with high stakes, and limited research exists on understanding the roles of students' personality traits and social-evaluative threat on their academic performance. This study examined the roles of avoidance temperament (i.e., fear and behavioral inhibition) and evaluative threat (i.e., fear of failure and being viewed as unintelligent) in standardized math test and course grades in college students. Design and Methods: Undergraduate students (N = 184) from a large public university were assessed on temperamental fear and behavioral inhibition. They were then given 15 minutes to complete a standardized math test. After the test, students provided data on evaluative threat and their math performance (scores on standardized college entrance exam and average grades in college math courses). Results: Results indicate that avoidance temperament was linked to social-evaluative threat and low standardized math test scores. Furthermore, evaluative threat mediated the influence of avoidance temperament on both types of math performance. Conclusions: Results have educational and clinical implications, particularly for students at risk for test anxiety and underperformance. Interventions targeting emotion regulation and stress management skills may help individuals reduce their math and test anxieties.
