Term: The features of the environment to which the movement must mold

Learner must match the spatial and temporal characteristics

regulatory environmental conditions

Term: Background features of the environment, irrelevant features

Unnecessary for goal attainment

Distractible patients must learn to ignore the non-regulatory features of the environment

non-regulatory environmental conditions

Term: Environment or terrain or support surface is

fixed and objects or people are stationary

stationary

term: Environment or terrain or support surface,

objects or other people are in motion

motion

term: Regulatory conditions remain the same from one performance to the next performance

inter-trial variability- absent

term: Regulatory conditions change from one performance to the next performance

inter-trial variability - present

term: object(s) or environment is/are stationary & do/does not change from trial to trail

closed tasks

term: object(s) or environment is/are in motion and conditions change during this trial &/or upon the next trial(s)

open tasks

term (Body orientation)- information processing demands are low

boundaries of the environment are fixed to an area surrounding the performer

stabilization

term ( body orientation)-information processing demands are high

boundaries of the regulatory environment are constantly expanding in accord with the rate of motion

transportation

Term (manipulation of objects)- UEs/hands yoked to postural system

absent

Term (manipulation of objects)- requires freeing the UEs/ hands from the

postural system

present
