Embodied basis of invariant features in execution of whole-body dynamic actions-knacks and focuses of roll-and-rise motion

The attempts to discover the invariant features in a whole-body dynamic task under perturbations are discussed. The features were useful for execution and recognition of a task, and have their origin in human embodiment. The studies stated that a psychological experiment with a unique paradigm was carried out to investigate the relationship of the features to visual recognition of the same motion.
