Artificial intelligence detects awareness of functional relation with the environment in 3 month old babies

A recent experiment probed how purposeful action emerges in early life by manipulating infants’ functional connection to an object in the environment (i.e., tethering an infant’s foot to a colorful mobile). Vicon motion capture data from multiple infant joints were used here to create Histograms of Joint Displacements (HJDs) to generate pose-based descriptors for 3D infant spatial trajectories. Using HJDs as inputs, machine and deep learning systems were tasked with classifying the experimental state from which snippets of movement data were sampled. The architectures tested included k-Nearest Neighbour (kNN), Linear Discriminant Analysis (LDA), Fully connected network (FCNet), 1D-Convolutional Neural Network (1D-Conv), 1D-Capsule Network (1D-CapsNet), 2D-Conv and 2D-CapsNet. Sliding window scenarios were used for temporal analysis to search for topological changes in infant movement related to functional context. kNN and LDA achieved higher classification accuracy with single joint features, while deep learning approaches, particularly 2D-CapsNet, achieved higher accuracy on full-body features. For each AI architecture tested, measures of foot activity displayed the most distinct and coherent pattern alterations across different experimental stages (reflected in the highest classification accuracy rate), indicating that interaction with the world impacts the infant behaviour most at the site of organism~world connection

Movement in Mind: Dance, Self-Awareness and Sociality - An Investigation of Dance as Treatment/Therapy

Dance has always occupied a central place in human culture. Why humans dance, however, and the role of dance in health, are questions that have yet to be fully addressed. Research to this point has been challenged by limitations in study design, differences in qualitative/quantitative evaluations, and dualistic perceptions of body and mind. This study proposes a shift in explanatory framework and research methods for the examination of dance in therapeutic contexts. Incorporating methods and views from neurobiology, dance/movement therapy, embodied cognition, and somatic education, this interdisciplinary project presents an innovative study design and novel perspective on the role of dance as a treatment for conditions that may be understood as mental/physical or both. It concludes that the practice of dance is essential to human flourishing, and may best be understood as a behaviour that nurtures our human capacity to adapt and thrive
