ABSTRACT— The motor-program concept, emphasizing how actions are represented in the brain, helped bring the study of motor control into the realm of cognitive psychology. However, interest in representational issues was in limbo for much of the past 30 years, during which time the focus was on biomechanical and abstract accounts of the constraints underlying coordinated movement. We review recent behavioral and neuroscientific evidence that highlights multiple levels of constraints in bimanual coordination, with an emphasis on work demonstrating that a primary source of constraint arises from the manner in which action goals are represented. 相似文献

This is the second in a series of four papers which seeks to articulate theologically and practically the consequences of the ecclesial identity of the Catholic school. The series is based on the principle that the ‘marks’ of the Church – one, holy, catholic, and apostolic – are also marks of the Catholic school, since the Catholic school is within the Church and derives its ecclesial identity from the Church. Each paper analyses one of these ‘marks’, discerning what it means theologically and practically for the Catholic school. In this paper, the second of the marks of the Church and therefore of the Catholic school – holiness – is discussed in terms of what it means to be, and to continually become, holy. In reference to a current research project, Christian service programmes in Catholic schools are analysed in regard to what they already contribute to the formation in holiness of Catholic students, but also in terms of what more they may become. It is argued that for their potential for growth in holiness for teachers and students to be fully realised, Christian service programmes need to be more than just charitable works, and that they need to engage critically with inequity and injustice in keeping with the Church’s radical social teaching. 相似文献

Children with antisocial, aggressive and disruptive behaviour problems are among the most frequent referrals to mental health
services. These young people and their families present with a range of adverse contextual factors and can prove challenging
to engage. We examined the characteristics of children with conduct problems, treatment participation, and the impact of telephone
reminder calls. Consecutive referrals (N=262) to two child and youth mental health services were randomly assigned to either a reminder call condition or service
as usual. In comparison to referrals without conduct problems, conduct problem children presented with greater sources of
psychosocial adversity, attended fewer initial appointments and were at greater risk of treatment refusal. Importantly, telephone
reminder calls significantly increased treatment attendance, though only for participants with elevated conduct problems.
Telephone reminder calls, however, had no impact on treatment refusal, regardless of conduct problem status. The findings
highlight a straightforward approach for enhancing treatment participation among a group that has been challenging for mental
health services. 相似文献

Experience-dependent changes of spine structure and number may contribute to long-term memory storage. Although several studies demonstrated structural spine plasticity following associative learning, there is limited evidence associating motor learning with alteration of spine morphology. Here, we investigated this issue in the cerebellar Purkinje cells using high voltage electron microscopy (HVEM). Adult rats were trained in an obstacle course, demanding significant motor coordination to complete. Control animals either traversed an obstacle-free runway or remained sedentary. Quantitative analysis of spine morphology showed that the density and length of dendritic spines along the distal dendrites of Purkinje cells were significantly increased in the rats that learned complex motor skills compared to active or inactive controls. Classification of spines into shape categories indicated that the increased spine density and length after motor learning was mainly attributable to an increase in thin spines. These findings suggest that motor learning induces structural spine plasticity in the cerebellar Purkinje neurons, which may play a crucial role in acquiring complex motor skills. 相似文献

Even if together we could make poverty history, we would not all do our part. The paper presents a device that makes it more
likely for everybody to do his part. This is achieved by making everybody’s contribution dependent on the other people’s commitment
to contribute given that certain conditions are fulfilled. Furthermore, a device is introduced which, based on the same general
idea, doubles everybody’s donation. Finally, possibilities, assumptions and limitations of such devices are addressed. 相似文献
