Instruction Modes for Motor Control Skills Acquisition: A Randomized Controlled Trial

Abstract

The objective was to compare two different instruction modes used to teach patients with nonspecific chronic low back pain (CLBP) to perform a lumbar motor control task. The three intervention instruction modes used were: common verbal explanation of a motor task based on a motor control therapeutic exercise (MCTE-control group), MTCE instructed using motor imagery (MI) and MCTE instructed using tactile feedback (TF). The main outcome measure was lumbar motor control of the neutral position test. Forty-eight patients with CLBP were randomly allocated into three groups of 16 patients per group. The MI strategy was the most effective mode for developing the motor control task in an accurate and controlled manner, obtaining better outcomes than TF or verbal instruction.     

Directedness and engagement in chimpanzee vocal ontogeny

Directedness and engagement during pre-verbal vocal communication play a major role in language development. What was their role in the evolution of language? This question invites us to examine these behaviours in chimpanzee vocal ontogeny. We collected observational data on infant (N = 15) and juvenile (N = 13) chimpanzees at Chimfunshi Wildlife Orphanage, Zambia. We examined the impact of age and vocalization type (grunts, whimpers, laughs and screams) on directed cues (gaze directedness and face directedness) and engagement (mutual face directedness) during vocal communication. We also assessed the impact of directed cues and engagement on social interactions by coding the behaviour of social partners before, during and after a vocalisation, and examining whether they contingently changed their behaviour in response to the vocalisation if it was directed or if engagement occurred. We found that face directed vocalisations showed a general increase during ontogeny and we observed call-type dependent effects of age for mutual face directedness. Only face directed vocalisations were significantly predictive of behavioural responses in social partners. We conclude that like young humans, young chimpanzees routinely exhibit directed behaviours and engagement during vocal communication. This social competency improves during ontogeny and benefits individuals by increasing the chances of eliciting behavioural responses from social partners. Directedness and engagement likely provide a foundation for language phylogenetically, as well as ontogenetically.

Research Highlights

• We show that directedness and engagement routinely occur during early chimpanzee vocalisations.
• Directedness increases throughout chimpanzee vocal ontogeny, similar to human infants.
• Directedness enhances social partner responsiveness, demonstrating a direct benefit to this style of communication.
• Directedness and engagement could provide a route towards language phylogenetically as well as ontogenetically.

     

Stereotypes in the classroom's air: Classroom racial stereotype endorsement,classroom engagement,and STEM achievement among Black and White American adolescents

Initiatives promoting diversity, equity, and inclusion in predominantly White contexts, including STEM fields, have primarily relied on approaches to increase the representation of minoritized individuals. However, an increase in the representation of minoritized individuals is only one step of the process, as the present study suggests that explicit beliefs about particular racial groups’ abilities also matter. The present article examined whether classroom racial stereotype endorsement about science and math disadvantaged Black American adolescents relative to their White American peers. Across two longitudinal studies with 533 and 1,189 adolescents (N-adolescents = 1722; N-classrooms = 86; 45% Black American, 55% White American; 51% females; M-age = 13–14), classroom pro-White/anti-Black stereotype endorsement in the fall term predicted better science and math achievement scores for White American adolescents and lower science and math achievement scores for Black American adolescents at the end of the academic year. Student- and teacher-reported student engagement in science and math classrooms mediated the longitudinal relations between classroom pro-White/anti-Black stereotype endorsement and students’ achievement scores. Results suggest that classrooms may be important conduits for communicating racial stereotypes that create racially hostile STEM learning environments.

Research Highlights

• Using a longitudinal sample of 1722 adolescents enrolled in 86 classrooms, the present study examined the consequences of classroom racial stereotype endorsement during adolescence.
• White American adolescents demonstrated favorable achievement scores in science and math when their classmates endorsed traditional, or pro-White/anti-Black, stereotypes.
• Black American adolescents showed worse achievement scores in science and math when their classmates endorsed pro-White/anti-Black stereotypes.
• Classroom engagement mediated the longitudinal relations between classroom pro-White/anti-Black stereotype endorsement and achievement scores for both Black and White American adolescents.

     

Factorial validity of the Utrecht Work Engagement Scale (UWES) across occupational groups in Norway

Nerstad, C.G.L., Richardsen, A.M. & Martinussen, M. (2009). Factorial validity of the Utrecht Work Engagement Scale (UWES) across occupational groups in Norway. Scandinavian Journal of Psychology. The present study investigated the factorial validity of the Utrecht Work Engagement Scale (UWES) among 1266 participants from ten different occupational groups. Confirmatory factor analyses of the total sample, as well as multi‐group analyses and analyses of each of the ten occupational groups separately, indicated that a three‐dimensional model of both the UWES‐17 and the short version, UWES‐9, provided a better fit to the data than a one‐ and two‐dimensional model. The results of multi‐group analyses and analyses of each of the groups separately, indicated that with a few exceptions, the three‐factor model of work engagement provided the best fit. Results indicated factorial invariance and the internal consistencies were acceptable. The fit of the UWES‐9 was slightly better than the UWES‐17. It is concluded that the Norwegian short version may be recommended over the UWES‐17.     

Value congruence and teachers’ work engagement: The mediating role of autonomous and controlled motivation

This study aimed to examine the importance of value congruence in work engagement and to extend the previous literature by investigating the potential mediating effects of autonomous and controlled motivation in this relationship. The Perceived Value Congruence, Autonomous and Controlled Motivation and Work Engagement scales were administered to 767 teachers in Mainland China. Correlation analysis revealed that value congruence, autonomous and controlled motivation and work engagement were significantly correlated with each other. Furthermore, structural equation modeling (SEM) analysis showed that value congruence exerted its indirect effect on teacher’s work engagement through the mediating effect of autonomous and controlled motivation. These findings provide a new perspective to explain the complex association between value congruence and work engagement. The possible explanations and the research limitations are discussed.     

高中生价值观对学校投入的影响:未来目标和动机内化程度的中介作用

为了考察价值观是否可以通过未来目标和动机内化程度影响高中生的学校投入，对六个城市七所学校的1022名高一学生的价值观、未来目标、学习动机内化程度及学校投入进行了调查。结果表明：（1）自我超越型价值观和自我完善型价值观能够使青少年发展出内在未来目标以及较为内化的学习动机，进而更加努力学习，而物质主义价值观则会使青少年形成外在未来目标以及较为外化的学习动机，进而更少投入学习；（2）当考虑价值观对未来目标的作用时，内外在未来目标不影响青少年的学习动机，但影响学校投入；（3）当不考虑价值观对未来目标的作用时，内在未来目标能够促进青少年学习动机的内化，进而更多地投入到学习中，而外在未来目标则会阻碍青少年学习动机的内化，进而更少投入学习。研究结果表明青少年的价值观比未来目标对学习有更重要的影响，说明学生发展指导工作中更应该注重价值观教育。     

Solidarity and Community Engagement in Global Health Research

Abstract

Community engagement (CE) is gaining prominence in global health research. A number of ethical goals–spanning the instrumental, intrinsic, and transformative–have been ascribed to CE in global health research. This paper draws attention to an additional transformative value that CE is not typically linked to but that seems very relevant: solidarity. Both are concerned with building relationships and connecting parties that are distant from one another. This paper first argues that furthering solidarity should be recognized as another ethical goal for CE in global health research. It contends that, over time, CE can build the bases of solidaristic relationships—moral imagination, recognition, understanding, empathy—between researchers and community members. Applying concepts from existing accounts of solidarity, the paper develops preliminary ideas about who should be engaged and how to advance solidarity. The proposed approach is compared to current CE practice in global health research. Finally, the paper briefly considers how solidaristic CE could affect how global health research is performed.     

From prevention focus to adaptivity and creativity: the role of unfulfilled goals and work engagement

ABSTRACT

Whereas promotion focus is consistently linked to high adaptivity (i.e., adjustment to changes) and creativity (i.e., generation of useful and original ideas), prevention focus is commonly associated with low adaptivity and creativity. The present study uncovers the conditions under which prevention focus may also have positive effects on adaptivity and creativity. First, we hypothesize that trait-level promotion focus positively relates to day-level adaptivity as well as creativity. More importantly, we hypothesize that trait-level prevention focus positively relates to day-level adaptivity and creativity when day-level goal fulfilment is low (i.e., two-way interactions) and that these effects are stronger when day-level work engagement is high (i.e., three-way interactions). To test our hypotheses, we conducted a daily diary survey among 209 employees from different occupational sectors, over five working days. As expected, trait promotion focus was positively related to adaptivity and creativity. Furthermore, trait prevention focus positively related to both adaptivity and creativity when day-level goal fulfilment was low andday-level work engagement was high (3-way interactions). None of the two-way interaction effects of trait prevention focus and goal fulfilment was significant. Our findings suggest that prevention focus and unfulfilled goals jointly should not only be seen as threats, but also as opportunities for adaptation and creativity.
