Environnement psycho-technologique (EPT) et comportements d’apprentissage avec les technologies (CAT) : developpement et adaptation française de deux mesures

The 4th industrial revolution and the omnipresence of technologies have largely modified the work context and more specifically the learning process. We postulate the emergence of a new psycho-technological environment, which is characterized by more opportunities to learn and more accessible technologies. To our knowledge, no measurement can capture the perception of psycho-technological environment (PTE) and learning behaviors with technologies (LBT). The aim of this study is therefore to compensate for this lack of tools with the development of French-language. Two studies that combine 389 students were conducted. In the first study, based on a sample of 151 students, two scales were developed via an explanatory factorial analysis. In the second study, based on a sample of 238 students, a confirmatory factorial analysis confirmed the psychometric qualities of our scales. This first validation study shows good validity and fiability with the good psychometric qualities of our scales.     

非正式学习环境中幼儿的自发数量聚焦

大量从“能力”角度来探讨个体早期数学发展的研究仅专注于儿童早期的数学知识和技能, 而忽略了可能与儿童早期数学能力相关的方面。近年来, 数学认知发展研究者逐渐开始关注自发数量聚焦(Spontaneous focusing on numerosity, SFON), 即个体对环境中数量相关信息自发注意的认知倾向。SFON被视为其他数学聚焦倾向概念的基础, 但与自发数字聚焦(SAN)、自发阿拉伯数字聚焦(SFONS)和自发数量关系聚焦(SFOR)之间的联系仍需进一步明晰。作为数学表现的领域特异预测因子, 个体SFON的发展轨迹和作用机制是当前研究的重点所在。未来可从数学动机、数学焦虑等角度进一步探讨SFON的作用机制, 改良与创新SFON测量工具, 同时需深入推进家庭和学校场合的SFON干预研究。

大学生的冲动性特质与自杀意念的关系:一个有调节的中介模型

以应激-易感模型为依据考察冲动性特质与自杀意念的关系,并在此基础上提出一个有调节的中介模型,探讨负性生活事件影响的中介作用以及家庭环境的调节作用。采用巴瑞特冲动性量表、青少年生活事件量表、家庭环境量表、贝克自杀意念量表对902名大学生进行集体施测,旨在考察负性生活事件的影响对大学生冲动性特质与自杀意念的中介作用以及家庭环境的调节作用,结果表明:(1)冲动性特质和负性生活事件的影响能正向预测大学生的自杀意念;(2)负性生活事件的影响在冲动性特质和自杀意念之间起中介作用;(3)负性生活事件影响的中介作用和冲动性特质的直接作用受家庭环境的调节。这些结果对于综合解释环境与个体因素对自杀意念的作用与机制具有重要意义。     

学校归属感与学生发展的探索研究

采用问卷调查法探讨中小学生的学校归属感与学校适应、自我概念、同伴关系及班级环境的关系。结果表明:1)学校适应、自我概念、同伴关系和班级环境与中小学生的学校归属感有密切的关系;2)学校归属感能有效的预测学生的自我概念;3)师生关系和同伴关系对学校归属感有重要影响,是学校归属感显著的预测变量;4)学校类型对学校归属感有显著的影响,重点中学学生的学校归属感显著高于其他类型学校的学生。     

进化心理学对心理素质结构研究的整合与重构——以学生心理素质结构研究为例

传统的心理素质结构研究模式不经济,研究结果出现纵向断裂横向分裂的趋势.从进化心理学的视角来看,心理素质结构的最终功能均指向个体的适应性,其形成是与周围环境不断排斥和融合的过程.建构的心理素质结构融合模型能在一定程度上解决传统研究模式的弊端,并建议今后的研究应以分析人为主导转而分析人及其所处的文化环境并重,进而引导人的心理素质结构的不断发展.     

An Integrative Model Linking Feedback Environment and Organizational Citizenship Behavior

ABSTRACT

Past empirical evidence has suggested that a positive supervisor feedback environment may enhance employees' organizational citizenship behavior (OCB). In this study, we aim to extend previous research by proposing and testing an integrative model that examines the mediating processes underlying the relationship between supervisor feedback environment and employee OCB. Data were collected from 259 subordinate-supervisor dyads across a variety of organizations in Taiwan. We used structural equation modeling to test our hypotheses. The results demonstrated that supervisor feedback environment influenced employees' OCB indirectly through (1) both positive affective-cognition and positive attitude (i.e., person-organization fit and organizational commitment), and (2) both negative affective-cognition and negative attitude (i.e., role stressors and job burnout). Theoretical and practical implications are discussed.     

Dispositional pessimism but not optimism is related to sickness absence caused by musculoskeletal symptoms

Musculoskeletal disorders account for a higher proportion of sickness absence from work in the European Union than any other health condition. The present study examined the associations between work environment, dispositional optimism/pessimism and medically certified sickness absence caused by musculoskeletal complaints in a sample of employees from the Norwegian Armed Forces (N = 1190, 77.5% men). Dispositional pessimism, but not optimism, predicted the amount of absence also when taking into account the effects of age and the work environment. Overall, our results support previous studies suggesting that pessimism is a more salient predictor of physical health than optimism. Our results also suggest that it may be beneficial for employers to combine medical treatment of musculoskeletal symptoms with psychological treatment targeting pessimistic outcome expectancies in order to reduce the amount of sickness absence.     

What matters when children play: Influence of Social Cognitive Theory and perceived environment on levels of physical activity among elementary-aged youth

ObjectivesSocial Cognitive Theory (SCT) has often been used as a guide to predict and modify physical activity (PA) behavior. We assessed the ability of commonly investigated SCT variables and perceived school environment variables to predict PA among elementary students. We also examined differences in influences between Hispanic and non-Hispanic students.DesignThis analysis used baseline data collected from eight schools who participated in a four-year study of a combined school-day curriculum and environmental intervention.MethodsData were collected from 393 students. A 3-step linear regression was used to measure associations between PA level, SCT variables (self-efficacy, social support, enjoyment), and perceived environment variables (schoolyard structures, condition, equipment/supervision). Logistic regression assessed associations between variables and whether students met PA recommendations.ResultsSchool and sex explained 6% of the moderate-to-vigorous PA models' variation. SCT variables explained an additional 15% of the models' variation, with much of the model's predictive ability coming from self-efficacy and social support. Sex was more strongly associated with PA level among Hispanic students, while self-efficacy was more strongly associated among non-Hispanic students. Perceived environment variables contributed little to the models.ConclusionsOur findings add to the literature on the influences of PA among elementary-aged students. The differences seen in the influence of sex and self-efficacy among non-Hispanic and Hispanic students suggests these are areas where PA interventions could be tailored to improve efficacy. Additional research is needed to understand if different measures of perceived environment or perceptions at different ages may better predict PA.     

Acceptance by athletes of a virtual reality head-mounted display intended to enhance sport performance

While a growing number of studies have highlighted the potential of virtual reality (VR) to improve athletes’ skills, no research has yet focused on acceptance of a VR head-mounted display (VR-HMD) designed to increase sport performance. However, even if technological devices could potentially lead to performance improvement, athletes may not always accept them. To investigate this issue, the Technology Acceptance Model (TAM) examines if perceived usefulness, perceived ease of use, perceived enjoyment, and subjective norms (i.e., social influence) are positive predictors of intention to use a specific technology. The aims of the present study were to test with competitive athletes the validity of the TAM before a first use of a VR-HMD intended to enhance sport performance and to examine to what extent the level of practice and the type of sport practiced have an influence on the previous variables of the TAM. The study sample comprised 1162 French athletes (472 women, 690 men, M_age = 24.50 ± 8.51 years) who usually practiced a sport in competition (from recreational to international level). After reading a short text presenting the VR-HMD and its interests for sport performance, the participants filled out an online questionnaire assessing their acceptance of this technological device before a first use. The results of the structural equation modeling analysis revealed that perceived usefulness, perceived ease of use, perceived enjoyment, and subjective norms were positive predictors of intention to use this VR-HMD, validating the suitability of the TAM for investigating the acceptance by athletes of a VR-HMD designed to increase their sport performance. The results also showed that athletes of all sport levels (a) had a significant intention to use VR, (b) found it quite useful (except for recreational athletes), quite easy to use, and quite pleasant to use, even if their entourage would not encourage them to use it (except for international athletes), and (c) found the VR-HMD easy and pleasant to use whatever the sport practiced. Notably some athletes (e.g., triathletes, swimmers, cyclists) did not find the VR-HMD significantly useful and did not have significant intention to use it to increase their performance. Identifying acceptance by athletes of such a device may increase the likelihood that it will be used by athletes of different levels and from different sports, so that they can benefit from all its advantages related to the improvement of their sport performance. Needs-based targeted interventions may also be conducted toward athletes who might be reluctant to integrate this type of device into their training.
