A cognitive collaborative reinforcement learning algorithm (CCRL) that incorporates an advisor into the learning process is developed to improve supervised learning. An autonomous learner is enabled with a self awareness cognitive skill to decide when to solicit instructions from the advisor. The learner can also assess the value of advice, and accept or reject it. The method is evaluated for r...

A computerized version of the Tower of London task was used to investigate cognitive skill learning. Thirty-six healthy volunteers were assigned to either a random condition (nonrecurring problems), or to a sequence condition in which, unbeknownst to the subjects, a repeating sequence of three problems was presented. Indices of execution, planning, and total time, as well as number of moves per...

BACKGROUND Studies demonstrate that both doctors and patients may use adrenaline auto-injector improperly and the usage skills are improved by training. In this study, we aimed to determine the appropriate frequency of training to maintain skills for adrenaline auto-injector use. METHODS We invited all interns of 2011-2012 training period. At baseline, all participants were given theoretical ...

Individual differences in skill acquisition are influenced by several architectural factors. According to Ackerman’s theory, general intelligence, speed of proceduralization and psychomotor speed influence different stages of skill acquisition. The ACT-R cognitive architecture allows for direct testing of this theory by manipulating parameters that correspond to these factors. The present study...

We investigated the acquisition of music performance skills in novice and expert pianists. Temporal disruptions in novice performances coincided with constraints in planning capacities. Child and adult pianists ranging in age (9-26 years), training (3-15 years) and sight-reading ability learned to perform a novel musical piece in eleven practice trials. Computer-detected pitch and timing errors...

Generation of a sequence of behaviors is necessary for the RoboCup Humanoid league to realize not simply a individual robot performance but also cooperative ones between robots. A typical example task is passing a ball between two humanoids, and the issues are: (1) basic skill decomposition, (2) skill learning, and (3) planning to connect the learned skills. This paper presents three methods fo...

This paper presents a general approach to specify and execute complex robot tasks considering uncertain environments. Robot tasks are defined by a precise definition of socalled skill primitive nets, which are based on Mason’s hybrid force/velocity and position control concept, but it is not limited to force/velocity and position control. Two examples are given to illustrate the formally define...
