Analysis of Motor Behavior based on Recurrence Analysis in adults with Autism Spectrum and Neurotypicals in a Dynamic Balance Task: a pilot study

Mirjam Altenburg, Catarina Farinha, Carolina Santos, Cristiana Mercê, David Catela, Marco Branco
2021 Cuadernos de Psicologia del Deporte  
This strategy could be linked to the autistic's stereotypical behavior of continuously cyclical movements. However, this does not result in greater variability in movement, but less variability.  ...  Given the neuro-motor difficulty of these autistic adults in producing varied ranges of motion, it is recommended to introduce dynamic balance activities, starting with reduced levels of postural stability  ...  The present study Cuadernos de Psicología del Deporte, 21, 3 (octubre) Altenburg et al. 240 provides a deeper insight into the features of PC in ASD, supporting the hypothesis that their stereotypic  ...

Motions of the Hand Expose the Partial and Parallel Activation of Stereotypes

Jonathan B. Freeman, Nalini Ambady
2009 Psychological Science  
In the work described here, participants, presented with sex-typical and sex-atypical faces (i.e., faces containing a mixture of male and female features), identified which of two gender stereotypes (one  ...  As participants stereotyped sex-atypical faces, real-time motor responses exhibited a continuous spatial attraction toward the opposite-gender stereotype.  ...  We conclude that the attraction toward the opposite stereotype in the atypical condition is due to the parallel activation of that stereotype rather than a less decisive movement toward the selected stereotype  ...

Movement variation constitutes a crucial feature of infant motor development.  ...  A stereotypy score based on dynamic time warping has been developed describing movements which are self-similar in multiple degrees of freedom.  ...  Comparing this function with the original timeseries one can see that the algorithm is able to detect movement segments which exhibit stereotyped behavior.  ...
