Associations between procrastination,personality, perfectionism,self-esteem and locus of control

To date, many variables but particularly trait-like psychological constructs have been found to strongly contribute to procrastination but the complex relations among these variables collectively have received almost no attention. The purpose of the study was to provide a more profound understanding of the relations between procrastination, perfectionism, big five personality, locus of control and self-esteem. Young adults (162 women, 80 men: M?=?20.98) completed measures of academic procrastination, self-esteem, big five personality, perfectionism and locus of control. Parental criticism was a significant correlate of procrastination, while personality traits of conscientiousness, agreeableness and organisation were inversely associated with procrastination behaviour. These findings suggest that personality-based intervention approaches with the inclusion of family can be more influential in procrastination prevention and treatment.     

质地密度逐渐变化对触觉识别的作用

研究关于输入、本体感受和输出对表面触觉认知的影响,旨在探索运用触觉识别质地密度逐渐变化的表面时,理论关于表面粗糙度恒定的情况下,主动手指运动产生的信息不影响触觉认知的解释是否仍然成立。实验采用表面质地密度呈正态曲线式逐渐变化,组成正负两组变化方向。正方向变化为表面质点密度向中逐渐增大,与手指触摸运动的加减速方式一致;负方向变化为表面质点密度向中逐渐减小,与手指触摸运动的加减速方式相反;另外包括一个表面密度不变的平面。让被试辨别表面质地密度变化的方向,结果发现被试能够很好地判别表面质地密度变化的方向,但在判别正向变化的表面时显得更准确;当表面密度没有变化时,被试倾向于判别为正向变化。这一发现没有支持表面密度恒定的触觉认知解释模型。与常规直觉相反,研究还发现即时反馈并没有改进触觉识别,反而降低了辨别的正确率。质地密度逐渐变化的触觉识别在变化的大小、准确和自信心方面都显示了不同,但没有发现认知学习作用该触觉任务辨别的过程。基于这些发现,文章讨论了触觉质地感知和有关存在的理论解释模式。     

Infants' use of material properties to guide their actions with differently weighted objects

Two studies with 9‐, 11‐ and 13‐month‐old infants were conducted to investigate infants' ability to use an object's material properties to guide their object‐directed actions. In study 1, 9‐ and 11‐month‐old infants played in an exploration phase with two objects made of different materials, one very heavy and the other one light and playable. Subsequently, when given the choice between both objects in a preferential reaching task, only the 11‐month‐olds' used the object's material information to remember and choose the lighter object. In study 2, 11‐ and 13‐month‐old infants underwent the same exploration phase. In the test phase, novel objects made of the same materials were offered. The 13‐ but not the 11‐month‐olds chose the objects made from the same material as the lighter object in the exploration phase. Additionally, infants' performances in the reaching task were positively correlated with their exploratory behaviour during the exploration phase. Altogether, the studies show a developmental progression in the use of an object's material information to guide infants' action. The results are discussed in respect to infants' perception of object properties and their implications for the development of physical knowledge. Copyright © 2010 John Wiley & Sons, Ltd.     

团体辅导改善大学生人际关系及心理健康水平的实证研究

目的:探讨团体心理辅导对改善大学生人际关系及心理健康水平的有效性及可行性。方法:采用单因素重复测量设计自然实验,对16名有改善人际关系愿望的大学生进行为期2个月,共10次的团体心理辅导干预;使用人际关系综合诊断量表和症状自评量表前后施测,结合团体成员的反馈自评和表现进行质的分析。结果:被试人际关系综合诊断量表前后测有差异(t=2.55,p<0.05),症状自评量表总分有显著差异(t=3.12,p<0.01),其中抑郁、敌对因子有显著差异(抑郁因子t=2.95,敌对因子t=2.71),人际关系和偏执因子有差异(人际关系因子t=2.53,偏执因子t=2.57)。结论:人际交往团体辅导对改善大学生的人际关系,提高心理健康水平是有效的。     

Vanishing Boundaries: When Teaching About Religion Becomes Spiritual Guidance in the Classroom

Abstract. This article revisits the pedagogical dilemma of maintaining neutrality in the religious studies/theology classroom. I argue that if the boundary between teaching about religion and actually teaching spirituality seems to be vanishing, it is because the boundary was inappropriately constructed in the first place. To the extent that the religious concepts, even when compressed into religious studies categories, inherently inspire personal transformation, how can a boundary exist between the ideas students encounter and the power of those ideas to transform? Spiritual guidance emerges naturally in the academic study of religion, and those of us who teach in the field might as well get used to it. In explaining my position, I draw on my experience as a teaching assistant in Professor Walter Capps's course, “Religion and the Impact of the Vietnam War.” I, then, develop a pragmatic teaching strategy, neutral enthusiasm, which preserves the important neutrality of classroom presentation in religious studies courses, yet recognizes the unavoidable evocative power present in the intellectual territory that is religion. Neutral enthusiasm allows the content to do the work.     

The influence of robotic guidance on error detection and correction mechanisms

New technologies have expanded the available methods to help individuals learn or re-learn motor skills. Despite equivocal evidence for the impact of robotic guidance for motor skill acquisition (Marchal-Crespo, McHughen, Cramer, & Reinkensmeyer, 2010), we have recently shown that robotic guidance mixed with unassisted practice can significantly improve the learning of a golf putting task (Bested & Tremblay, 2018). To understand the mechanisms associated with this new mixed approach (i.e., unassisted and robot-guided practice) for the learning of a golf putting task, the current study aimed to determine if such mixed practice extends to one’s ability to detect errors. Participants completed a pre-test, an acquisition phase, as well as immediate, delayed (24-h), and transfer post-tests. During the pre-test, kinematic data from the putter was converted into highly accurate, consistent, and smooth trajectories delivered by a robot arm. During acquisition, 2 groups performed putts towards 3 different targets with robotic guidance on either 0% or 50% of acquisition trials. Only the 50% guidance group significantly reduced ball endpoint distance and variability, as well as ball endpoint error estimations, between the pre-test and the post-tests (i.e., immediate retention, 24-h retention, and 24-h transfer). The current study showed that allowing one to experience both robotic guidance and unassisted (i.e., errorful) performances enhances one’s ability to detect errors, which can explain the beneficial motor learning effects of a mixed practice schedule.     

触觉二维图像识别的认知机制

触觉二维图像可以辅助视觉受损人群, 将视觉信息转化为触觉信息, 从而感知外部世界。触觉二维图像的识别可能是通过触觉信息在大脑中进行“视觉转化”的方式而完成, 并且会受到图形的几何特征、视角与透视、视觉经验、视觉表象能力、触觉探索过程、训练以及年龄的影响。探索触觉二维图像识别的认知神经机制, 对于触觉二维图像设计的改进和可用性的提高, 具有重要意义。     

Emotionally guiding our actions

If emotions have a rational role in action, then one challenge for accounting for how we can act rationally when acting emotionally is to show how we can guide our actions by our emotional considerations, seen as reasons. In this paper, I put forward a novel proposal for how this can be so. Drawing on the interconnection between emotions, cares and caring, I argue that, as the emotional agent is a caring agent, she can be aware of the emotional consideration as a pro tanto reason favouring an action choice and, even, as the reason for which she should act.     

Applying phenomenography in guidance and counselling research

This paper examines phenomenography as a viable qualitative approach in guidance and counselling research. A phenomenographic study maps the qualitatively different ways in which people experience a specific phenomenon and helps researchers to describe the aspects that make one way of experiencing a certain phenomenon qualitatively distinct from another. This paper presents an overview of phenomenographic research, encompassing theoretical, methodological and practical considerations. The application of this approach in guidance and counselling studies is illustrated with examples.
