Final Exam Flashcards
(58 cards)
SR+/-
Positive and negative reinforcement
SP+/-
Positive and negative punishment
S Delta
Extinction
Form vs. Function
Form = the topography of the behavior
Function = the purpose that a behavior serves
Instructional Hierarchy
Acquisition: skills, slow and deliberate (accuracy)
Proficiency: fluency, sub-skills as a unit
Maintenance: can engage with little effort
Generalization: can use the skills in different environments
Adaptation: Make small changes to the skills to be applied to different situations
Prerequisite Skills
Behaviors the must be mastered prior to advancing to a more complex behavioral response
Schedules of Reinforcement
Fixed
Variable
Time
Ratio
The response effort required in order for a learner to receive reinforcement
Reinforcer vs. Reward
Reinforcer: a consequence that increases the likelihood that a behavior will occur again in the future
Reward: a bribe to elicit a desired response
Operant Conditioning
Altering the strength or frequency of properties of behavior through reinforcement, extinction, or punishment procedures.
Motivating Operations: EO’s and AO’s
EO: A procedure that alters the degree to which a specific postcedent will function as a reinforcer.
AO: A procedure that alters the degree to which a specific postcedent will not function as a reinforcer.
Conditioned Motivating Operation - Reflexive
A warning stimulus that an aversive stimulus or set of stimuli is forthcoming.
Establishes escape as temporarily reinforcing
Evokes behavior that will allow for the termination of the CMO-R and by proxy escape, avoid, or postpone the impending aversive
Need to abolish CMO-R in the instructional setting
Stimulus Control
Previously neutral stimuli become SDs
In the presence of these stimuli the organism exhibits a specific response
Discrimination
Only respond to specific stimuli
Simple Discrimination
Distinguish between SD and S-delta
Ex. Pigeons were taught to peck a key in order to gain access to food pellets
Conditional Discrimination
More complex response requirement
Involves multiple (2 or more) discriminative stimuli
Match to sample: “Touch cat” - array of 3 pictures
Generalization
One of the 7 defining characteristics of ABA
Across time, settings, people, behaviors
Generalizations to situations outside of training
Same response under the presence of different stimuli
Generalization occurs on a spectrum
Strategies to Generalize
Select target behaviors that will meet natural contingencies
Specify all desired variations and the settings/situations in which it should or should not occur
Teach multiple exemplars
Good representation of different responses and environments
Teach multiple response topographies
Explicit instruction of where and when not to use the target bx
Instructional setting should be as similar to the generalization setting as possible (program common stimuli)
Teach loosely (Vary non-critical aspects in the instructional setting)
Program indiscriminable contingencies (no clear stimuli that signals reinforcement is available)
Premack Principle
First…, then…
Imitation and Modeling
Behavioral cusp
Model stimulus is presented to evoke imitative behavior
Formal similarity
Model is an SD for the behavior response
If the behavior occurs in the absence of a model it is not imitation
Generalized Imitation
Generalize a rule to imitate models
Teach learners to “do what the model does”
Naturalistic Teaching
Techniques conducted in loosely controlled contexts
Multiple exemplars
Incorporate child’s preference into teaching
Free Operant Teaching
May or may not be programmed SD
Several responses
No intertrial interval
Ex. Practicing flashcards by yourself, shooting hoops by yourself, greeting people in a lunchroom
Leads to lower rates of responding compared to DTT
Good for testing generalizability of a skill
Pivotal Response Teaching
Motivation
Initiations
Self-regulation
Responding to multiple cues
Incidental Teaching
Hart and Risley
Primarily used for teaching language
Setting up scenarios for children to express their wants or needs
Naturally occurring reinforcement
