EDF 6223 EXAM 2
Formal similarity
occurs when the model's and the imitator's behavior physically resemble each other
and are in the same mode
Model
an antecedent stimulus with topographical similarity to the behavior the analyst
wants to be imitated
Planned models
prearranged demonstrations of behavior that show the learner exactly what to do, be
it acquiring new skills or refining the topography of certain elements of existing skills-
can be live or filmed
Unplanned models
occasion imitation in everyday social environments
What is the most important property defining imitation?
,the controlling relation between a model's demonstration and a learner's
performance of topographically similar behavior
T/F: an imitative behavior is a new behavior that follows a novel antecedent event
T/F: an imitative behavior is a new behavior that follows a novel antecedent event
True
Modeling
a behavior change strategy in which learners acquire new skills by imitating
demonstrations of the skills by live or symbolic models.
The model shows, demonstrates, or conveys exactly the behavior the learner is
expected to convey. can be live, symbolic, or recorded
Shaping
the differential reinforcement of successive approximations toward a terminal
behavior. the antecedent stimulus for the terminal behavior stays the same, while
the response progressively becomes more differentiated
Differential reinforcement
presenting an unconditioned or conditioned reinforcer only to those emitted
members of a response class that share a specified dimension or quality, while
placing all other emitted response class members on extinction
, Performance dimensions that can be shaped
1. topography: refining motor movements
2. rate: increasing number of correct responses
3. latency: decreasing compliance time between a directive
4. duration: increasing time spent on task
5. IRT: reducing rapid eating
6. magnitude: increasing projected voice volume
Shaping guidelines
1. select the terminal behavior and define it precisely
2. determine the criterion for success
3. assess the response repertoire
4. identify behaviors to reinforce
5. eliminate interfering or extraneous stimuli
6. proceed gradually
7. limit the number of approximations at each level
8. continue to reinforce when terminal behavior is achieved
