We introduce CST, an algorithm for constructing skill trees from demonstration trajectories in continuous reinforcement learning domains. CST uses a changepoint detection method to segment each trajectory into a skill chain by detecting a change of appropriate abstraction, or that a segment is too complex to model as a single skill. The skill chains from each trajectory are then merged to form ...

BACKGROUND A competitive Carrick Institute Competitive Grant (CG7-523) was obtained to explore what skills were taught and what assessment of practice approaches were used in nursing programmes in Australia. The intention was twofold; firstly to identify what skills were being taught which would contribute to the development of an assessment of practice toolkit for eligibility to practice progr...

We tested the assumptions of Attentional Control Theory (ACT) by examining the impact of anxiety on anticipation using a dynamic, time-constrained task. Moreover, we examined the involvement of high- and low-level cognitive processes in anticipation and how their importance may interact with anxiety. Skilled and less-skilled tennis players anticipated the shots of opponents under low- and high-...

The aim of the present study was to conduct within-gymnast analyses of biological movement variability in impact forces, elbow joint kinematics and kinetics of expert gymnasts in the execution of the round-off with different hand positions. Six international level female gymnasts performed 10 trials of the round-off from a hurdle step to a back-handspring using two hand potions: parallel and T-...

Medical curriculum revisions all over the world in the last 20 years have increased the number of teaching hours in communication skills. This article describes a concrete communication skills teaching programme focused on general practice. Since the spring of 1992, more than 2,000 physicians from Denmark, Sweden and Finland have attended courses within this programme in Kalymnos, Greece. The t...

the meaning of an idiomatic expression cannot be transparently worked out from the meanings of its constituent words due to its figurative and unpredictable nature. consequently, the syntactic composition and the structural paradigm of an idiomatic expression are supposed to be the same in every context. however, this is not the case in the institutionalized second language varieties of english...

Several intervention strategies, and systems have been proposed developed to facilitate the understanding of SQL language, it’s skill acquisition. However, most these interventions are mainly structured around a battery assessments mostly overlooking participants’ engagement patterns. Ergo, large amounts easily avoidable errors, which syntactic, generated in course student’s exercise task engag...

UNLABELLED When learning a new language, we build brain networks to process and represent the acquired words and syntax and integrate these with existing language representations. It is an open question whether the same or different neural mechanisms are involved in learning and processing a novel language compared with the native language(s). Here we investigated the neural repetition effects ...

Development of cognitive architecture where the agents at different levels exhibit different levels of thinking. The paper primarily focus on building the skill tree at the learning layer of the architecture. These include the discovery of one’s own body, including its structure and dynamics. Also the acquisition of associated cognitive skills such as self and non-self-distinction. This can be ...
