Biographic and behavioral factors are associated with music-related motor skills in children pianists

This study aimed to identify biographical and behavioral factors associated with children pianists’ motor skills using an objective assessment of a music-relevant motor task. Motor skills at the piano were assessed in 30 children pianists by measuring temporal unevenness in standardized scale playing using musical instrument digital interface (MIDI)-based scale analysis. Questionnaires were used to collect detailed information about the amount of time playing the piano, practice characteristics, attitudes toward music and practice, and the environment of music and practice. Associations between performance values and variables from the questionnaire were investigated using multivariable linear regression. A higher number of years playing the piano, more frequent parental involvement in the child’s practice, more frequent practice of technical exercises, and greater enjoyment of practice and of the visual arts were associated with better motor performance. In addition to cumulative experience and aspects of practice, extrinsic motivational factors (e.g., parental interest) and intrinsic motivational factors (e.g., an artistic disposition) were associated with better performance on a musically-relevant motor task in children pianists.     

The coupling between gaze behavior and opponent kinematics during anticipation of badminton shots

PurposeWe examined links between the kinematics of an opponent’s actions and the visual search behaviors of badminton players responding to those actions.MethodA kinematic analysis of international standard badminton players (n = 4) was undertaken as they completed a range of serves. Video of these players serving was used to create a life-size temporal occlusion test to measure anticipation responses. Expert (n = 8) and novice (n = 8) badminton players anticipated serve location while wearing an eye movement registration system.ResultsDuring the execution phase of the opponent’s movement, the kinematic analysis showed between-shot differences in distance traveled and peak acceleration at the shoulder, elbow, wrist and racket. Experts were more accurate at responding to the serves compared to novice players. Expert players fixated on the kinematic locations that were most discriminating between serve types more frequently and for a longer duration compared to novice players. Moreover, players were generally more accurate at responding to serves when they fixated vision upon the discriminating arm and racket kinematics.ConclusionsFindings extend previous literature by providing empirical evidence that expert athletes’ visual search behaviors and anticipatory responses are inextricably linked to the opponent action being observed.     

Individual differences in emotion elicitation in university examinations: A quasi-experimental study

In a quasi-experimental study, we examined the role of individual differences in the elicitation of emotional states in university examinations. Specifically, we assessed emotional states (a) before the first examination (baseline), (b) after receiving positive or negative feedback, and (c) then, again, before a series of subsequent examinations. We also measured effort in examination preparation and interest for studying. Data were collected during a university course that consisted of seven examinations in one semester; and 94 female students completed the BIS/BAS scales and SPSRQ (to measure sensitivity to punishment, SP, and reward, SR). Results revealed that higher BAS, but not SR, individuals experienced higher positive affect (PA) following positive feedback and they also showed higher levels of interest in studying. More generally, higher BIS and SP individuals experienced higher level of negative affect (NA) and they invested more effort in examination preparation; and both higher levels of SP and SR correlated positively with NA after receiving negative feedback. In addition, following negative feedback, higher BAS individuals experienced lower levels of PA, and higher SR individuals invested less effort in examination preparation. Results are discussed in terms of the reinforcement sensitivity theory (RST) of personality and directions for future research.     

Extending hierarchical achievement motivation models: The role of motivational needs for achievement goals and academic performance

In the current study, we investigated the role of three basic motivational needs (need for power, affiliation, achievement) as antecedents of goals within the 2 × 2 achievement goal framework, and examined their combined predictive validity with regard to academic performance in a sample of 120 university students. Structural equation modeling analysis largely supported our postulated model, linking motivational needs indirectly to course grades through goals. Achievement goals were formed by a combination of different motives: need for achievement was a positive predictor of all four achievement goals, and need for affiliation was negatively related to performance-approach and performance-avoidance goals. Additionally, need for power was a positive predictor of performance-avoidance goals. Performance-approach goals had a direct (positive) effect on performance outcomes. In sum, our results integrate basic motivational needs with the achievement goals literature and extend therefore hierarchical achievement motivation models, by showing how basic human motives of achievement, affiliation, and power are related to goal striving motivation and performance outcomes in an academic setting.     

道德型领导者得到了什么？道德型领导、团队平均领导-部属交换及领导者收益

道德型领导是新近提出的一种领导理论,大量研究证实这种领导方式会对员工和组织带来积极影响。然而,在领导过程中处于主体地位的领导者从中获得了什么收益却较少受到关注。以50个工作团队的248名员工为研究对象,本研究基于社会交换理论考察了道德型领导与个体层次和团队层次上领导者收益的关系及其作用过程。跨层次分析结果表明：(1)道德型领导对个体层次的员工对领导的认知信任和情感信任,以及团队层次的团队绩效和领导者绩效均有显著正向作用;(2)团队平均领导-部属交换中介了道德型领导与下属对领导者的认知信任、情感信任以及团队绩效的关系,但在道德型领导与领导者绩效关系间无显著中介作用。本文揭示了道德型领导者在领导过程中获得的“收益”以及团队层次社会交换的中介作用,为道德型领导和团队社会交换的研究提供了启示。     

Examining impacts of technostress on the professional salesperson's behavioural performance

This paper examines the concept of technostress in the professional sales area and shows it to be a possible reason for low technology-enabled behavioural performance of professionals in the sales function. Integrating literature from sales, technostress and social cognitive theory, we examine relationships between technostress creators, role stress, technology-enabled innovation and technology-enabled performance. We hypothesize that technostress adversely affects the technology-enabled performance of the salesperson through two distinct paths, one by increasing role stress and two, by decreasing technology-enabled innovation. We further examine the role of factors that mitigate these adverse effects. We find that organizational technostress-inhibiting mechanisms negatively moderate the positive relationship between technostress creators and role stress, and technology self-efficacy dampens the negative association of technostress and technology-enabled innovation. We also find that technology-enabled innovation enhances technology-enabled performance. Our results are based on survey data collected from 237 institutional sales professionals. Theoretical contributions and practice-based implications of findings are discussed.     

An assessment of needed sales management skills

The skills required of sales managers are vitally important to the success of the firm's selling effort; however, there has not been a recent review that identifies these needed skills. Based on a survey of sales executives from 145 companies, this research develops a taxonomy of key sales management skills. The perceived importance of these skills is reported based on the level of management, gender and the performance level of the firm. In addition to identifying the relative importance of the various sales management skills, they were found to group into three conceptual dimensions relating to interpersonal, technical and strategic skills. The results also indicate that significant differences in the perceived level of skill importance exist based on level of management, years managing salespeople, gender and on three dimensions of the respondent's firm performance.     

Which influence tactics lead to sales performance? It is a matter of style

The application of influence is a key behaviour set at the heart of the sales role. But we know little about how or whether influence tactics affect salespeople's actual job performance. We extend existing research on salespeople's use of influence by: (1) showing that influence tactics can be used to predict objective sales performance (and delineating which tactics are most predictive); (2) demonstrating that the effect of tactics on performance varies across salespeople, and these patterns of influence effectiveness allow us to identify different influence ‘styles’ and (3) revealing that the influence styles our data uncover are not consistent with existing theoretical classifications of influence tactics. The article concludes with a discussion of theoretical and managerial implications, and directions for future work.     

Structuring for team success: The interactive effects of network structure and cultural diversity on team potency and performance

This longitudinal study used data from 91 self-managed teams (456 individuals, 60 nationalities) to examine the interactive effects of a team’s task (“workflow”) network structure and its cultural diversity (as indexed by nationality) on the team’s “potency” (i.e., the team’s confidence in its ability to perform) and its performance (as rated by expert judges). We found that whereas the emergence of dense task networks enhanced team potency it was the emergence of (moderately) centralized task networks that facilitated team performance. These varied structural effects, moreover, were themselves contingent on team composition: the more culturally diverse a team, the more pronounced were the positive effects of network density on team potency and the higher the level of network centralization required for optimal team performance. The success of a team appears to hinge on the interplay between network structure and team composition.     

What do we know about the effects of mental training applied to combat sports? A systematic review

ObjectivesThis study aimed to investigate the effects of mental training applied to combat sports athletes.MethodsA systematic review was conducted, following the criteria recommended by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, from inception up to February 2021, with an electronic search in PubMed, Scopus, Web of Science, PsycINFO, and SPORTDiscus databases. As eligibility criteria, this review included original studies that carried out any type of mental training, with or without a control group, acute or chronic, in combat sports athletes, of both sexes, age >16 and < 45 years old, from any competitive level, and evaluated the effect of these interventions on psychological measures. The quality assessment was conducted through the application of the Cochrane Collaboration tool.ResultsIn total, 1921 studies were found and after application of the inclusion and exclusion criteria, 21 articles were included in this review. A total of 417 subjects were investigated from the 21 studies. As results, despite the variations in the type and characteristics of the interventions, studies showed that mental training seems to improve anxiety, mood, self-confidence, emotions, cohesion, emotional balance, and relaxation, in addition to physical and athletic performance.ConclusionsThis systematic review based on the evidence from the selected studies indicates that mental training seems to be beneficial for athletes in combat modalities, while combat sports can benefit from mental training in preparation, competition, and recovery. However, the interpretation of these findings must consider that there is limited scientific production with good quality studies investigating the effects of psychological intervention protocols in athletes of combat sports in different combat modalities.Prospero register numberCRD42020169793.
