The ecological task analysis provides a way to standardize a so performers can easily be compared with each other (or with themselves on different occasions).

Assessment

Explanation:

Ecological task analysis (ETA), originally presented by Davis and Burton in 1991, is perhaps the most detailed and comprehensive model which applies dynamical systems and related theories to the assessment and intervention of movement development.  A dynamical system is a term that broadly refers to the stability and change ‑‑ or dynamics ‑‑ of various physical and biological systems.  In the context of human movement, "dynamical systems" refers more specifically to the stability and change, and the nonlinearity of movement form as a function of the interaction between performer attributes, environmental context, and the intended task goal.
