“a relatively permanent change in behavior that results from practice.” ( Atkinson et al 1993 ).
Learning is acquiring new knowledge, behaviors, skills, values, preferences or understanding, and may involve synthesizing different types of information.
Through Säljö (1979) research, learning fell into five main categories:
Learning as a quantitative increase in knowledge.
Learning as memorizing.
Learning as acquiring facts, skills, and methods.
Learning as making sense or abstracting meaning.
Learning as interpreting and understanding reality in a different way.

Behavior
• is more concerned with behavior than with thinking, feeling, or knowing. It focuses on the objective and observable components of behavior.
• The behaviorist theories all share some version of stimulus-response mechanisms for learning
• The neo-behaviorists, then, were a transitional group, bridging the
gap between behaviorism and cognitive theories of learning.
The behavioral learning theory generated by B.F
Skinner that is based upon the idea that learning is a function of change in behavior.
Changes in behavior are the result of an individual’s
response to events (stimuli) that occur in the environment.
Burrhus Frederic Skinner (March 20,
1904 – August 18, 1990) was born in
Susquehanna, Pennsylvania to Grace and William Skinner
He was an American psychologist, author, inventor, social philosopher, and poet.
Skinner received a PhD from Harvard in 1931, and remained there as a researcher until 1936.
He then taught at the University of Minnesota at
Minneapolis and later at Indiana University, where he was chair of the psychology department from 1946–
1947, before returning to Harvard as a tenured professor in 1948.
In 1948, he joined the psychology department at
Harvard University where he remained for the rest of his life
He became one of the leader of behaviorism and his work contributed immensely to experimental psychology.
He also invented the “Skinner BOX”, in which a rat learn to obtain food by pressing a lever
BF Skinner
As a behaviorist, Skinner believed that internal
thoughts and motivation could not be used to explain behavior
He suggested to look only at the external, observable
causes of human behavior.
Skinner used the term “operant” to refer to any active behavior that operates upon the environment to generate consequences
Operant conditioning (sometimes referred to as
instrumental conditioning) is a method of learning that occurs through
rewards / reinforcement and punishments for behavior.
Through operant conditioning, an association is made between
a behavior and a consequence for that behavior
We can find examples of
operant conditioning at work all around us in increasing the behavior
Children completing homework to earn a reward from a parent or teacher
Operant conditioning can also be used to decrease
the behavior by removal of an undesirable outcome or the use of punishment
The children are required to attend the retention class if they did not completed their homework

Increase Behavior Decrease Behavior
Positive
Reinforcement
If you stroke a cat's fur in a manner that is pleasing to the cat it will purr. The cat's purring may act as a positive reinforcer , causing you to stroke the cat's fur in the same manner in the future.
Negative
Reinforcement
When a child says "please" and "thank you" to his/her mother, the child may not have to engage in his/her dreaded chore of setting the table. Therefore, not having to set the table will act as a negative reinforcer and increase the likelihood of the child saying "please" and "thank you" in the future.
Positive
Punishment
If you stroke a cat's fur in a manner that the cat finds unpleasant, the cat may attempt to bite you. Therefore, the presentation of the cat's bite will act as a positive punisher and decrease the likelihood that you will stroke the cat in that same manner in the future
Negative
Punishment
When a child "talks back" to his/her mother, the child may lose the privilege of watching her favorite television program.
Therefore, the loss of viewing privileges will act as a negative punisher and decrease the likelihood of the child talking back in the future.
B.F Skinner
A Skinner Box is a often small chamber that is used to conduct operant conditioning research with animals
It is an experimental environment that is better suited to examine the more natural flow of behavior.
B.F Skinner became famous for his work with rats using his “Skinner Box” (is also referred to as an
operant conditioning chamber).
Within the chamber, there is usually a lever (for rats) or a key (for pigeons) that an individual animal can operate to obtain a food or water within the chamber as a reinforcer.
The chamber is connected to electronic equipment that records the animal's lever pressing or key pecking, thus allowing for the precise quantification of behavior.
The animal’s presses on the levers can be detected and recorded and a contingency between these presses, the state of the stimulus lights and the delivery of the reinforcement can be set up, all automatically.
A Skinner box typically contains one or more levers which an animal can press, one or more stimulus lights and one or more places in which reinforcers like food can be deliver
Reinforcement component
Partial
Reinforcement reinforcement is given only part of the times they gives the desired response.
Ratio
Reinforcement
Partial reinforcement is when you're reinforced after a number of the
desired behaviors.
Fixed ratio schedules
Variable ratio schedules
Continuous
Reinforcement reinforcement is given every
time they gives the desired response.
Interval
Reinforcement
With interval schedules you're reinforced only after a certain interval of time

Ratio Reinforcement Fixed Reinforcement
Fixed ratio
Schedules deliver reinforcement after every specific number of response
Variable ratio schedules deliver reinforcement after a random number of responses (based upon a predetermined average)
Fixed interval
Schedules deliver reinforcement for the first response after a fixed length of time since the last reinforcement, while premature responses are not reinforced.
Variable interval
Schedules deliver reinforcement for the first response after a random average length of time passes since the last reinforcement
Example: every second response is reinforced
Lab example: rat reinforced with food after each 5 bar-presses in a
Skinner box.
Real-world example:
The student must make three requests using the word “please” before being reinforced.
Advantages
Builds a high response rate. The higher the ratio, the higher the rate.
Disadvantages
An irregular burst of responding can occur if the reinforcement is stopped.
Example: on average, every third response is reinforced
Lab example: 1 st times 3 times pedal 1 food /2 nd times
5 times 1food / on average, a rat is reinforced for each 10 bar presses
Real world example:
The student may be reinforced on the average three requests. Thus, he may be reinforced following four requests using the word
“please” or following two appropriate requests.
Advantages
Because of its unpredictable.
Reinforcement schedule, the student’s rate of responding remains essentially constant and resistant to extinction.
Disadvantages
Not effective for teaching new behaviors
Example: reinforcement provided for the first response after 1 second
Lab example: rat is reinforced for the first bar press after 15 seconds passes since the last reinforcement
Real world example:
After 5 minutes has passed, the teacher reinforces the next request in which the student uses the word
“please.”
Advantages
Ease of implementation
Disadvantages
The student stops performing following the reinforcement and begins to work again just prior to the next reinforcement period
Example: reinforcement is provided for the first response after an average of
3 seconds since the last reinforcement.
Lab example: rat is reinforced for the first bar press after an average of 10 seconds passes since the last reinforcement
Real world example:
The student receives reinforcement on the average of every 5 minutes for using the word “please” when making a request. Sometimes the reinforcement occurs after 3 minutes or sometimes after 6 minutes.
Advantages
Ease of implementation. Because the time intervals are of different lengths, the student never knows which response will be reinforced.
This unpredictability creates a steady pattern of responding
Disadvantages
Not effective for teaching new behaviors
When teaching new skills or behaviors, make sure the student understands what behavior is required to earn the reward. Then, each time he performs the behavior,
immediately reinforce him. Timing is everything.
• The shorter the delay between the behavior and
reinforcer, the greater the chance the behavior will be strengthened or increased.
• In contrast, the longer the delay between the behavior and reinforcer, the greater the risk that
another behavior will be inadvertently reinforced.
