Taxonomy of Tasks

Question 1

Regulatory Environmental Conditions

Answer 1

• The features of the environment to which the movement must mold
• Learner must match the spatial and temporal characteristics of the task
• Ex: the density of the foam pt is standing on

Question 2

Non-regulatory Environmental Conditions

Answer 2

• Background features of the environment, irrelevant features
• Unnecessary for goal attainment
• Distractible patients must learn to ignore the non-regulatory features of the environment
• Ex: the color of the foam pt is standing on

Question 3

Stationary

Answer 3

• Environment or terrain or support surface is fixed and objects or people are stationary
• the performer is free to decide when to start and stop a movement
• the performer is free to decide how long to continue a movement
• Ex: place stationary objects in an environment

Question 4

Motion

Answer 4

• Environment or terrain or support surface, objects or other people are in motion
• the performer must match both spatial & temporal characteristics of the environment
• must interpolate or extrapolate information
• Ex: roll a ball in the environment

Question 5

Inter-trial variability - absent

Answer 5

• regulatory conditions remain the same from one performance to the next performance
• the need to monitor the environment decreases
• free to direct attention elsewhere
• Ex: always walking around the same thing—like a stationary cone

Question 6

Inter-trial variability - present

Answer 6

• regulatory conditions change from one performance to the next performance
• results in more variable movements with practice
• requires attention & on-going problem solving
• movements become more diversified, flexible and adaptable

Question 7

Closed Tasks

Answer 7

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

Question 8

Closed Task: Consistent Motion tasks

Answer 8

the motion of the object(s) or environment stays the same during repeated trials

Question 9

Closed Task: Variable Motionless Tasks

Answer 9

object(s) or environment is/are stationary during the present trial but may vary in position, configuration, texture, etc. during the next trial(s)

Question 10

Open tasks

Answer 10

• object(s) or environment is/are in motion and conditions change during this trial &/or upon the next trial(s)
• Ex: standing on a bus, walking on an airplane

Question 11

Body Orientation - Stabilization

Answer 11

• information processing demands are low
• boundaries of the environment are fixed to an area surrounding the performer
• Ex: trying to stand on a bus while it’s moving

Question 12

Body Orientation - Transportation

Answer 12

• information processing demands are high
• boundaries of the regulatory environment are constantly expanding in accord with the rate of motion
• client may slow down to adjust time to process information

Question 13

Manipulation of Objects - absent

Answer 13

• UEs/hands yoked to postural system
• the during walking - arm swing
• sitting with UE support
• dynamic posture- UE as part of equilibrium reaction
• walking with a cane or walker –bc it’s part of walking

Question 14

Manipulation of Objects - present

Answer 14

• requires freeing the UEs/ hands from the postural system
• the requires significant attentional demands (multi-tasking or dual-tasks)
• carry a glass of water while walking
• reading a flyer while walking
