Do Perceptual Instructions Lead to Enhanced Performance Relative to Behavioral Instructions?

As people we commonly instruct people in terms of physical actions to carry out to perform any task. However, according to perceptual control theory (Powers, 1973 Powers, W. T. (1973). Behavior: The control of perception. Chicago, IL: Aldine. [Google Scholar]), human action serves to control perception. Using a drawing task, it was hypothesized that instructions describing the perceivable effects of the movement would result in greater accuracy of image drawing than those describing the movement. Participants were asked to draw images using different instructions; describing the expected perceptions and describing the movements. As predicted, it was found that describing the perceptual outcome of the task led to significantly more accurate drawings than describing the movements did. This highlights the importance of instructions based on desired perceptions when precise execution of a skill is necessary.     

自我效能感影响航线飞行安全绩效的多重中介模型

采用问卷法调查了138名民航飞行员,探讨了自我效能感对飞行安全绩效的影响,以及在这一影响过程中组织信任、组织承诺和工作投入的作用。结果显示,自我效能感对组织信任、组织承诺、工作投入和安全绩效有直接正向作用。组织信任在自我效能感对组织承诺、工作投入、安全绩效的影响中有部分中介作用。组织承诺与工作投入在自我效能感对安全绩效影响中发挥着部分中介作用。结论:自我效能感对安全绩效有直接效应,并可通过组织信任、组织承诺和工作投入对安全绩效产生间接影响。     

未来工作自我清晰度对主动职业行为的影响——一个有调节的中介模型

基于主动性行为模型和生涯建构理论探讨未来工作自我清晰度对主动职业行为的影响机制。采用主动职业行为量表、未来工作自我清晰度量表、生涯适应力量表、同事支持量表对广深两地13所民营企业的195名员工进行调查分析。结果显示:(1)未来工作自我清晰度影响主动职业行为;(2)生涯适应力在其中起到部分中介作用;(3)同事支持在中介模型的前半路径起到调节作用。     

身体活动与学业成绩:来自具身认知的启示

具身认知理论认为身体、认知和环境是和谐的统一体。以该理论为基础的具身学习认为,身体不是学习过程的无关因素或障碍因素,身体是学习的主体,身体活动的参与在塑造学习者的思维、判断及记忆等心智活动中具有重要作用。当前已有一定数量的实证研究发现,身体活动能够显著提供语言习得、数学学习等学业成绩,提供学生在同伴中的社会地位。将来,可基于具身认知的角度,采用认知神经科学、心理学和教育学等跨学科合作的方式,进一步探讨具身学习影响学业成绩的因素及其机制。     

Proactive vitality management in the work context: development and validation of a new instrument

In the present research, we use proactivity literature and studies on energy at work to argue that individuals may proactively manage their vitality (i.e., physical and mental energy) to promote optimal functioning at work. We develop and validate a scale to measure proactive vitality management (PVM), and explore the nomological network. We conducted a five-day diary study (N = 133; 521 days), a survey study (N = 813) and a cross-sectional study measuring daily PVM (N = 246) among working individuals from various occupational sectors. The results show that PVM can be reliably measured with eight items that load on one overall factor, both on general and daily level. Furthermore, daily PVM was moderately but positively related to the use of work-related strategies and micro-breaks. Moreover, PVM related positively to relevant personal characteristics (i.e., proactive personality and self-insight) and showed moderate but positive relationships with job crafting and relaxation (convergent validity). PVM was unrelated to psychological detachment and decreasing hindering demands (discriminant validity). Finally, PVM was positively related to well-being, in-role work performance, creative work performance and performance on the Remote Associates Test (criterion validity). We conclude that employees may promote their own work performance through the use of PVM.     

Procrastination and predictor variables among a group of dental students in Turkey

The aim of this study was to assess the prevalence of procrastination among a group of Turkish dental students and to determine the predictors and consequences of procrastination. A total number of 273 females and 179 males (aged between 18 and 28) were included in the study. Tuckman procrastination scale, Academic Life Satisfaction Scale, Concern over Mistake Scale, Poor Time Management Scale, Self-Doubt Scale, Irrational Beliefs about Studying Scale, Positive and Negative Affect Schedule and Life Satisfaction Scale were used to gather data. Results indicated that 50% of participants were more likely to procrastinate their academic assignments or tasks. Procrastination score did not differ according to gender. The findings suggested that procrastinating students had a higher level of poor time management, self-doubt and irrational beliefs about studying, and poor academic performance and well-being than their non-procrastinating counterparts. Preventive strategies are necessary to overcome procrastination which affects the academic achievement, satisfaction, and well-being of dental students.     

“Please watch right” – Evaluation of a speech-based on-demand assistance system for urban intersections

In a driving simulator study we evaluated a speech-based driver assistance system for urban intersections (called Assistance on Demand AoD system) which supports the driver in monitoring and decision making. The system provides recommendations for suitable time gaps to enter the intersection based on the observation of crossing traffic. Following an “on-demand”-concept, the driver activates the assistance only if support is desired.In one drive, drivers used the AoD system in every situation they experienced to guarantee that every driver had the same exposure to the system when evaluating it. During another drive, drivers were free to decide if they want to use the system or not. The experimental study compared the AoD system with driving manually and with driving supported by a more conventional visual-based system which was always active at intersections (system showing colored arrows in a simulated head-up display (HUD) to visualize the crossing traffic). This resulted in four drives the drivers had to perform. Every drive consisted of several intersections with varying traffic conditions. The drivers had to turn left at every intersection.A total of 24 drivers took part in the study; one group with 14 middle-aged drivers and another group with ten high-aged drivers. Several questionnaires and online ratings were used to assess drivers’ acceptance, perceived usefulness, benefits and specific characteristics of both system variants. In addition, driving behaviour with regard to gap choice and drivers’ monitoring behaviour (using head tracking data) were analyzed.The results show that the AoD system reaches high acceptance ratings and is preferred compared to the visual, always active system. Using the speech modality for communication and the on-demand concept were both highly appreciated by the drivers. With regard to driving behaviour, the AoD system is comparably safe as manual driving while at the same time making driving easier by facilitating the monitoring of vehicles while waiting at an intersection.     

Recherche de feedback et performance au travail : l’effet modérateur des orientations vers les objectifs

This paper examines the relationship between the search for positive and negative feedback and job performance, as rated by supervisors, as a function of employees’ goal orientations (learning, performance, and avoidance). Based on a study among 197 employees from various industries, the relationship between the search for positive feedback and job performance was found to be stronger and positive when either learning, performance, or avoidance goal orientation was high, revealing the effects consistently favorable of positive feedback. In contrast, the search for negative feedback exerted a negative effect on job performance among employees who held a high performance goal orientation. We discuss the implications of these findings for our understanding of the effects of feedback-seeking behavior on job performance.     

Grit and academic performance among first-year university students: A brief report

This study examined grit and academic performance among a sample of South African university students (n = 121, mean age = 19.55, SD = 1.77, female = 57.85%). Data were collected using the Grit Scale and academic performance was assessed over one academic semester. Simple regression analysis was computed to predict students’ academic achievement from components of their self-reported grit. The grit component of consistency of interest accounted for 3% of the variance in the student’s academic achievement scores. Similarly, the grit component of perseverance of effort explained 9% of the variance in scores. Students who scored high on the Grit Scale also obtained higher academic marks compared to participants who scored low on the same instrument. The findings suggest that grit is an important personal resource for higher education students.
