Motor control information recovering from the dynamics with the EP hypothesis

چکیده
A global inversion procedure from the acoustic signal to motor commands is presented here based on a postural target invariance hypothesis. Using a model of vowel production, dynamic motor commands were inferred for a vowel sequence pronounced under different levels of emphasis stress and rate. The results enable to assign a prosodic role to the dynamic parameters of the model and thus to discriminate between slow vs fast or stressed vs unstressed utterances. Reliability of the results was assessed by computing the sensitivity of the model around the inferred motor commands and running perceptual tests on the synthetic stimuli generated from these values.

متن کاملEvolution of Motor Control: From Reflexes and Motor Programs to the Equilibrium-Point Hypothesis.
This brief review analyzes the evolution of motor control theories along two lines that emphasize active (motor programs) and reactive (reflexes) features of voluntary movements. It suggests that the only contemporary hypothesis that integrates both approaches in a fruitful way is the equilibrium-point hypothesis. Physical, physiological, and behavioral foundations of the EP-hypothesis are cons...
متن کاملEffect of Rhythmic Movements on working Memory, Motor Proficiency and Writing Skills in the Students with Dysgraphia
Introduction: One of the most common abnormalities of learning is dysgraphia, which refers to a serious defect in mechanical writing skills. Children with dysgraphia may not be able to perform the actions required to write or transfer information within the hearing or vision to exercise and poorly performing in cognitive skills such as organization, attention and memory. Evidence suggests that ...
