1. Task Analysis

2. Task Analysis Breaking a complex behavior into its component parts
Develop sequence of steps
Determine terminal behavior/skill
Develop a detailed description of each component behavior
List in order
Must perform task to make list
Assess student’s entry behavior

3. Task Analysis Prepare Kool-Aid Brushing Teeth Get spoon Get Kool-Aid
Get pitcher
Get cup
Put 2 scoops in pitcher
Take pitcher to sink
Fill pitcher to line
Stir Kool-Aid
Put spoon in sink
Brushing Teeth
Pick up toothpaste
Unscrew cap
Pick up toothbrush
Squeeze paste on brush
Place toothbrush bristles on teeth
Makes brushing motions on teeth

4. Task Analysis Data Sheet
(Insert task analysis data sheet here)
Determine chaining procedure
Establish initial cue to start chain
List special instructions
Fill in criteria

5. Task Analysis Data Sheet
(Insert task analysis data sheet here)
Prescribe training step
Prescribe prompting level
Determine trial type

6. Task Analysis Flow Chart

7. Behavior Chains (Stimulus-Response Chains)
A sequence of related behaviors, each of which provides the cue for the next, and the last of which produces a reinforcer
Each step in a chain results in a change in the environment
This change is a conditioned reinforcer for the behavior that preceded it
This also becomes a discriminative stimulus for the next step in the chain

8. Development of Behavioral Chain
Antecedent Behavior
(Sd) (Response)
“Make Kool- Get spoon
Aid” Get Kool-Aid
Spoon in hand Get pitcher
Kool Aid in hand Put 2 scoops in
Pitcher on table pitcher
Dry mix in pitcher Put in water
Water and mix in Stir Kool-Aid
pitcher
Consequence
(Conditional Response)
Spoon on table
Kool-Aid on table
Pitcher on table
Kool-Aid in pitcher
Water and mix in pitcher
Kool-Aid ready

9. Develop your own Task Analysis
“Can I have an Altoid?”

10. Chaining
The instructional procedure of reinforcing individual responses for occurring in sequence to form a complex behavior
Forward Chaining
A chaining procedure that begins with the first element in the chain and progresses to the last element
Backward Chaining
A chaining procedure that begins with the last element in the chain and progresses to the first element

11. Prompting Prompt Fading
An antecedent that induces a person to perform a behavior that otherwise does not occur
Fading
Gradually reducing the strength of a prompt

12. Prompting Hierarchies
Most to least
Manual guidance
