Quiz 8 SAFMEDS WEEK 10

Chaining

Various methods for linking specific sequences of stimuli and response to form new performance

Forward Chaining

a method for teaching behavior chains that begins with the learner being prompted and taught to perform the first behavior in the task analysis

Backward Chaining

A teaching procedure where training completes all but the last bx in a chain which is performed by the learner who’s bx is reinforced for completing the chain

Total Task Chaining

a variation of forward chaining where the learner receives training on each bx in the chain during each session

Three methods for identifying and validating a task analysis

1)Observe a component performer, 2)execute the task yourself, 3)expert input

Behavior Chain

A sequence of response where each response produces a stim change that functions as conditioned reinforcer for that response and as a discriminative stimulus for the next response in the chain

Behavior Chain interruption strategy

Link in the chain is made unavailable at a predetermined time so that another bx can be prompted or omitted

Extinction

the discontinuation in the r of reinforcement of a behavior that has been previously reinforced primary effect is a decrease in the frequency of the behavior until it reaches a prereinforced level or ultimately ceases to occur

Escape Extinction

Bx maintained with negative reinforcement are places on escape extinction when those behaviors are not followed by the termination of the aversive stimulus, emitting target bx does not enable person to escape the aversive stimulus

Extinction Burst

An increase int eh frequency of responding when an extinction procedure is initially implemented, temporary gets worse before it gets better

Resistance to Extinction

the relative frequency with which operant behavior is emitted during extinction

Sensory Extinction

A procedure by which behaviors maintained by automatic reinforcement are placed on extinction by masking or removing the sensory consequence

Spontaneous recovery

a behavioral effect is associated with extinction where the bx suddenly begins to occur after its frequency has decreased to its prereinforced level or stopped entirely

Three or four variable that affect resistance to extinction

Continuous vs intermittent reinforcement, Motivating operations, response effort, magnitude and quality of reinforcement
