What is a contingency independant/
An antecedent event which is not dependant on the consequences of behaviour for developing evocative and abative effects.

A contingency dependant
Describe the key features of NCR?
is a non contingent reinforcement
is an antecedent intervention
Stimuli with known reinforceing properties are delivered on a FT or VT schedule
Independant of the learners behaviour
Reinforcers that maintain problem behaviour are frequently and freely available
What is the rationale for presenting stimuli with known reinforcing properties rather than simply presenting reinforcers
The enriched environment may function as an abolishing operation for reducing the motivation to engage in problem behaviour.
What 3 features enhance the effectiveness of NCR
The amount and quality of stimuli with konwn reinforcing properties
Most treatments include extinction
Reinforcer preference can change during intervention.
Describe the procedure tp determine the intial NCR
Divade total duration of all B/L sessions by the total number of occurences of problem behaviour recorded during B/L
Set the initial interval at or slightly below the quotient.
What 3 components can be manipulated as part of a function based treatment for behaviour maintained by social reinforcement
1) Discriminative stimulus
2) Motivating operation
3) reinforcing consequence
What is FCT?
Funtional Communication Training
What does FCT involve?
The manipulation of the consequence for behaviour in 2 ways;
1) DRA reinforcer is delivered contingent on appropriate behaviour
2) The consequence is no longer delivered contingent on problem behaviour
How would you use FCT to address a problem behaviour maintained by social negative reinforcement?
The individual is taught to request breaks from non preferred tasks with an FCT response
How would use NCR to address a problem behaviour maintained by social negative reinforcement?
Escape is provided on a dense time based schedule
Describe 1 limitation of using these procedures under such circumtances?
When intially applied to negativley reinforced behaviour the individual frequently escapes all or almost all of the instructional demands.
Therefore the individual is not learning new skills or benefiting from the instruction
