Robots are increasingly used for substituting various tasks that were previously performed by humans. However, certain can only be accomplished To substitute such tasks, robots should able to reproduce the motion of There two steps achieving this goal. First, human needs measured properly using sensors. Second, need controlled motion. In particular, present study focuses on second step and prop...

A central service of a constraint programming system is search. In almost all constraint programming systems search is based on trailing, which is well understood and known to be efficient. This paper compares trailing to copying. Copying offers more expressiveness as required by parallel and concurrent systems. However, little is known how trailing compares to copying as it comes to implementa...

Eye movements and eye-hand interactions have been recorded for 10 beginner art students copying complex lines representing outlines of caricature heads seen in profile. Four copying conditions mimicking real-world drawing situations were tested: Direct copying where the original and copy were placed side by side, Direct Blind copying where the subject could not see the drawing hand and copy, Me...

The present work documents how the logic of a model's demonstration and the communicative cues that the model provides interact with age to influence how children engage in social learning. Children at ages 12, 18, and 24 months (n=204) watched a model open a series of boxes. Twelve-month-old subjects only copied the specific actions of the model when they were given a logical reason to do so--...

Cube-copying is often used to assess constructional ability of brain-damaged patients and the influence of unilateral spatial neglect is often pointed out in patients with right hemisphere lesions. However, some patients with severe neglect perform cube-copying satisfactorily. The aim of the present study is to identify the factors that affect the performance of cube-copying in patients with le...

Moving in a co-ordinated fashion with another individual changes our behaviour towards them; we tend to like them more, find them more attractive, and are more willing to co-operate with them. It is generally assumed that this effect on behaviour results from alterations in representations of self and others. Specifically, through neurophysiological perception-action matching mechanisms, interp...
