It accounts for experimental observations on human bimanual coordination that revealed fundamental features of self-organization: multistability, and phase transitions (switching). [2] HKB is one of the most extensively tested quantitative models in the field of human movement behavior.
A study suggests, "path dependencies, increasing returns to scale and learning-by-doing cost reductions can produce sudden, tipping-point-like transitions that cannot be extrapolated from past system behaviour", and that "historically, technological innovation and government policies often motivated by energy security concerns have also, in ...

On the other hand, there are other theoretically based, scientific perspectives that better represent the course of grief and bereavement such as: trajectories approach, cognitive stress theory, meaning-making approach, psychosocial transition model, two-track model, dual process model, and the task model.
