Behavioral Theory
CD 446
C. Knox, Instructor
Philosophical Foundation
Realism - reality as directly given to the
senses, objective, observable,
measurable. Can be examined
experimentally.
Experimental Psychology – Wundt,
Pavlov, Watson
Learning
Learning is based on the association of
elements, the building of connections in
the brain
All responses are learned
Complex forms are based on the
association of other simpler forms through
branching, stringing or other combining
processes
Levels of behavior




Reflexes
Respondents
Habits
Conscious choices
(innate/automatic)
(conditioned)
(habituated)
(mediated)
Conditioning


Classical: SR (Pavlov, Watson)
Operant: SRC (law of effect)
Thorndike, Skinner


Mediated Operant: SROCK
Learning is facilitated through
management of these components in
building and reinforcing associations
 Generalization, Discrimination, Extinction
Consequences and Contingencies
Antecedents (stimulus control)
Cueing, prompting, task analysis
Consequences and effects
Positive and negative reinforcement
Primary and conditioned reinforcers
Positive and negative punishment
Extinction
Contingencies
Continuous, interval, ratio
Applied Behavior Analysis
The importance of the baseline in the
ABAB model
Description of the behavior
Why and to whom is the behavior a
problem or a desired outcome?
Analysis of the antecedents and current
reinforcers
Design, implementation and evaluation of
intervention
Steps in Implementing Behavior
Management
Observe and specify behaviors
Set Behavioral Goals
Objectively described observable outcomes
Determine appropriate reinforcers
Select procedures for changing behavior
Implement procedures and record results
Evaluate progress and revise
Generalize; move to self maintenance
Interventions
Premack principle
High frequency and low frequency behaviors
Task analysis and shaping
Positive practice
“Catch them being good”
Reinforcement teaches more than
punishment
It takes more reinforcement to make an
impression
Maintenance Strategies
Reinforcement

Timing
Reinforcement occurs
consistently
Fixed Ratio

word spelled wrong
Fixed Interval
Weekly spelling test
Reinforcement occurs
intermittently

Generalization
Stimulus generalization – somewhat like
over generalization in language, people
may over generalize a response
CER’s – conditioned emotional responses
often compound generalization and create
problems for discrimination (classically conditioned)
Stimulus discrimination – Identifying key
elements of stimulus which differentiate it
from other similar stimuli
Some Common Classroom Strategies
Expectations, rules and consequences
MUST be known up front and enforced
uniformly
Public records
Group consequences
Token systems; Classroom/school store
Contingency contracts
Cautions
Punishment does not teach positive
behavior; it only stops behavior. It must
always be paired with reinforcement of
behavior to be learned.
You cannot use behavioral theory
effectively unless you know the baseline
characteristics of your learners
Strategies must be learner specific
You must continually observe and adapt
Food for thought
Children can only act in ways they have in
their repertoire and can match to stimuli
Self-management is the goal
Mastery and self-paced learning
Learned helplessness- a response to
continuous aversive or conflicting stimuli
Match between instruction and
assessment
Ethical benefits and challenges
