What is Learning?
Children are excellent learners.
What they learn, however, may not always be what we intend to teach.
Learning is usually defined as a change in an individual caused by experience.
Behavioral learning theories focus on the ways that pleasurable or unpleasant consequences of behavior change individual’s learning behavior over time.
Social learning theories focus on the effects of thought on action and action on thought.
What Are Behavioral Learning Theories?
Early research into learning studied the effects of stimuli on reflexive behaviors.
Ivan Pavlov contributed the idea of classical conditioning, in which neutral stimuli can acquire the capacity to evoke behavioral responses through their association with unconditioned stimuli that trigger reflexes.
B. F. Skinner continued the study of the relationship between behavior and consequences. He described operant conditioning, in which reinforcers and punishers shape behavior.
Pavlov: Classical Conditioning
Pavlov and his colleagues while studying the digestive system of dogs noticed changes in the timing and rate of salivation of these animals.
Unconditioned stimulus: provoked the response without any prior training. (In this case: the meat.)
Unconditioned response: automatic behavior in the presence of the unconditioned stimulus without any prior training. (In this case: salivation.)
Neutral stimuli: has no effect on the response in question. (In this case: bell.)
Conditioned stimulus: gains the power to illicit the response after being paired with the unconditioned stimulus. (bell paired with meat results in salivation at sound of bell.)
Skinner: Operant Conditioning
Skinner proposed that reflexive behavior accounts for only a small proportion of all actions. He proposed another class of behavior, he labeled operant behaviors.
Skinner’s work focused on the relation between behavior and its consequences.
The use of pleasant and unpleasant consequences to change behavior is often referred to as operant conditioning.
Skinner is famous for his development and use of the Skinner box, a device that contains a very simple apparatus for studying the behavior of animals, usually rats and pigeons.
What Are Some Principles of Behavioral Learning?
Behavioral learning theory has its own language to describe how consequences of behavior shape later behavior.
Reinforcers increase the frequency of a behavior, and punishers decrease its frequency.
Reinforcement can be primary or secondary, positive or negative.
Punishment involves weakening behavior by either introducing aversive consequences or removing reinforcers.
The Premack Principle states that a way to increase less-enjoyed activities is to link them to more-enjoyed activities.
The Role of Consequences
Perhaps the most important principle of behavioral learning theories is that behavior changes according to its immediate consequences.
Pleasurable consequences strengthen behavior; unpleasant consequences weaken it.
In other words, pleasurable consequences increase the frequency with which an individual engages in a behavior, whereas unpleasant consequences reduce the frequency of a behavior.
Reinforcers
A reinforcer is defined as any consequence that strengthens (that is, increases the frequency of) a behavior.
The effectiveness of the reinforcer must be demonstrated.
We cannot assume that a particular consequence is a reinforcer until we have evidence that it strengthens behavior for a particular individual.
No reward can be assumed to be a reinforcer for everyone under all conditions.
Intrinsic and Extrinsic Reinforcers
Often the most important reinforcer that maintains behavior is the pleasure inherent in engaging in the behavior.
People like to draw, read, sing, play games, hike, or swim for no reason other than the fun of doing it. Reinforcers of this type are called intrinsic reinforcers.
Extrinsic reinforcers are things like praise or rewards that are given to motivate people to engage in a behavior that they might not engage in without it.
Theory Into Practice
Classroom Uses of Reinforcement
Decide what behaviors you want from students, and reinforce these behaviors when they occur.
Tell students what behaviors you want; when they exhibit the desired behaviors and you reinforce them, tell them why.
Reinforce appropriate behavior as soon as possible after it occurs.
Punishers
Consequences that weaken behavior are called punishers.
Note that there is the same catch in the definition of punishment as in the definition of reinforcement.
If an apparently unpleasant consequence does not reduce the frequency of the behavior it follows, it is not necessarily a punisher.
Immediacy of Consequences
One very important principle of behavioral learning theories is that consequences that follow behaviors closely in time affect behavior far more than delayed consequences.
Waiting to give a rat in a Skinner box its food pellet for pressing a bar will significantly increase learning time for the connection between bar pressing and food; by the time the food arrives, the rat may be doing something other than bar pressing.
Shaping
Shaping through timely feedback on each step of a task is an effective teaching practice based on behavioral learning theory.
When you guide students toward goals by reinforcing the many steps that lead to success, you are using shaping.
Extinction
Extinction is the weakening and gradual disappearance of behavior as reinforcement is withdrawn.
Schedules of Reinforcement
Schedules of reinforcement are used to increase desired behavior probability, frequency, or persistence of desired behavior.
Reinforcement schedules may be:
Fixed or Variable
Schedules may be based on:
ratios or intervals
Schedules of Reinforcement
Maintenance
The principle of extinction holds that when reinforcement for a previously learned behavior is withdrawn, the behavior fades away.
Does this mean that teachers must reinforce students’ behaviors forever?
If you gradually increase the number of math problems a student must do to be praised and praise the student at random intervals (a variable-ratio schedule), then the student is likely to continue to do math problems for a long time with little or no reinforcement from you.
The Role of Antecedents
Antecedent stimuli serve as cues indicating which behaviors will be reinforced or punished.
Discrimination involves using cues to detect differences between stimulus situations.
Generalization involves responding to similarities between stimuli and the transfer or carryover of behaviors learned under one set of conditions to other situations.
How Has Social Learning Theory Contributed to Our Understanding of Human Learning
Social learning theory is a major outgrowth of the behavioral learning theory tradition.
Social learning theory is based on recognition of the importance of observational learning and self-regulated learning.
Bandura: Modeling and Observational Learning
Bandura noted that learning through modeling—directly or vicariously— involves four phases:
paying attention
retaining the modeled behavior
reproducing the behavior
being motivated to repeat the behavior
Bandura proposed that students should be taught to have expectations for their own performances and to reinforce themselves.
Bandura: 4 Phases of Observational Learning
Attentional phase. The first phase in observational learning is paying attention to a model. In general, students pay attention to role models who are attractive, successful, interesting, and popular.
Retention phase. Once teachers have students’ attention, it is time to model the behavior they want students to imitate and then give students a chance to practice or rehearse.
Reproduction. During the reproduction phase, students try to match their behavior to the model’s. In the classroom the assessment of student learning takes place during this phase.
Motivational phase. The final stage in the observational learning process is motivation. Students will imitate a model because they believe that doing so will increase their own chances to be reinforced.
Meichenbaum’s Model of Self-Regulated Learning
Students can be taught to monitor and regulate their own behavior.
Self-regulated learning strategies of this kind are often called cognitive behavior modification.
Meichenbaum developed a strategy in which students are trained to say to themselves:
What is my problem?
What is my plan?
Am I using my plan?
How did I do?
Strengths and Limitations of Behavioral Learning Theories
Behavioral learning theories are central to the application of educational psychology in:
classroom management
discipline
motivation
instructional models
Behavioral learning theories are limited in scope, however, in that they describe only observable behavior that can be directly measured.
