Action-based touch observation in adults with high functioning autism : can compromised self-other distinction abilities link social and sensory everyday problems?
No full textThe trombone as portrayed in Portuguese iconography during the sixteenth and early seventeenth centuries
No full textThis article studies eleven sixteenth and seventeenth century iconographical sources depicting slide brass instruments, by both Portuguese and foreign artists active in Portugal, as well as foreign artists depicting Portuguese scenes. This study addresses questions concerning aspects of trombone technique that have not previously been considered and may have implications in the way the trombone was understood elsewhere in Europe. It focuses on aspects of technique depicted that may be representative of the trombone’s contemporary design and performance and therefore the manner in which the instrument was held and indeed played. Finally, this article suggests a transitional technical period when the way of holding the single-slide trumpet may have been used to play the trombone.Publisher PD
Post-action determinants of the reported time of conscious intentions

90759.pdf (Publisher’s version ) (Open Access)The question of whether our behavior is guided by our conscious intentions is gaining momentum within the field of cognitive neuroscience. It has been demonstrated that the subjective experience that conscious intentions are the driving force of our actions, is built partially on a post hoc reconstruction. Our hypothesis was that this reconstructive process is mediated by an action-monitoring system that compares the predicted and the actual sensory consequences of an action. We applied event-related potentials (ERP) to a variant of the Libet's task in which participants were asked to press a button and to report the time of decision-will judgment (W) -to press. We provided delayed auditory feedbacks after participants' action to signify an action time later than the actual action. We found that auditory feedbacks evoked a negative component in the 250-300 time range, namely action-effect negativity (N-AE), that is thought to reflect the activity of a system that detects violation from expectancies. We showed that the amplitude of the N-AE was sensitive to the delay of the auditory feedback, with a larger amplitude for more delayed feedbacks. Furthermore, changes in the N-AE were also associated with changes in the reported W. These results not only confirm that we infer the time we decided to act from events occurring after the response, but these results also indicate that the subjective experience of when an action is decided is influenced by the activity of an action-monitoring system that detects mismatches between predicted and actual sensory consequences of the actions.9 p

Tics as a model of over-learned behavior: imitation and inhibition of facial tics
No full textBACKGROUND: Tics are the defining feature in Tourette syndrome and can be triggered by watching tics or single voluntary movements. This automatic imitation of movements referred to as "echopraxia" has been ascribed to a failure in top-down inhibition of imitative response tendencies. Alternatively, it could be interpreted in the context of automatic overlearned behavior. To this end, we investigated 18 Tourette patients aged 28.22 years (9.44 standard deviation; 16 male) and 24 healthy controls (mean age 29.21 years [9.1 standard deviation]; 17 male) using an adapted version of an action-interference paradigm.METHODS: Patients were asked to respond to 2 different auditory tones with either a facial movement that was part of their tic repertoire (tic-like movement), or a facial movement that was not (nontic movement). Simultaneously, behaviorally irrelevant videos of the 2 same facial movements were presented, which were either compatible or incompatible with the movement executed by the patient. Movements in healthy controls were matched to those in the patients.RESULTS: Healthy participants responded faster in compatible than in incompatible trials. Tourette patients showed the same effect for nontic movements. However, their responses were equally fast in incompatible and compatible trials when the movement they were asked to execute was a tic-like movement. Error rates did not differ between the groups.CONCLUSIONS: The results suggest that tic-like movements do not occur as a consequence of a failure to inhibit motor output. Instead, tics might be considered highly overlearned behavior that can be triggered without interference by external, incompatible movement stimuli. © 2016 International Parkinson and Movement Disorder Society.</p
