What can you teach a dog, a cat, and rat? Mostafa Ewees
Behaviorism Key Ideas
Deterministic - The way you act is determined by external stimuli provided by the culture in which you live.
Observable - Over time the individual develops a “behavioral repertoire” (Steinberg, 1980) that can be used to predict behavior.
Controllable - Desirable behaviors can be brought about by incentives; undesirable behaviors can be eradicated by consequences or punishment.
John B. Watson 1878 - 1958
John B. Watson
Watson changed the focus of psychology from introspection, to environmentalism.
The principles of learning would account for the largest share of behavioral development and are exercised almost exclusively through environmental learning opportunities provided for children. (reflected in cultural diversity & learning studies)
John B. Watson
He believed that environmental shaping of behavior began prenatally, and focused his studies on infants and children.
He demonstrated the conditioned response in the case of “Little Albert”(Watson, 1925), who was exposed to an alarming noise and a rat at the same time, and developed not only a fear of rats, but transferred the fear to all furry objects.
John B. Watson
Credited with “Definitional standards for stimuli and response and criteria for making objective and reliable observations can be traced back to Watson and continue to characterize acceptable investigatory practices today.”(Horowitz, 1992)
E.L. Thorndike 1874 - 1949
First scientific theory of learning- Theory of Connectionism
Comprehensive analogy of human learning- Three volume work, Educational Psychology ( 1913a, 1913b, 1914 )
Initial work with animal learning in laboratory setting- cat in box experiment”
What happened ?
The Cat Learned !!!
Behavior Change = Learning
Thorndike’s Theory of Connectionism
Law of Effect
If Situation + Response is followed by a positive consequence then the connection between the Situation + Response is strengthened.
If Situation + Response is followed by a negative consequence then the connection between the Situation + Response is weakened.
In Thorndike’s words:
“ When a modifiable connection between an situation and a response is made and is accompanied or followed by a satisfying state of affairs, that connection’s strength is increased: When made or accompanied or followed by an annoying state of affairs, the strength is decreased.” (Thorndike, 1913b)
Note: Thorndike(1932) later modified the Law of Effect when research showed that while positive consequences strengthened connections, negative consequences did not necessarily weaken them.
“ Spare the reward, spoil the child” by E.L. Thorndike
The Big Idea
Consequences of behavior effect behavior, responses resulting in satisfying consequences are learned.
Behavioral theories explain learning in terms of environmental events.
B.F. Skinner 1904 - 1990
As an organism is operating in its environment, it happens upon a reinforcing stimulus, or reinforcer. This reinforcer then causes the organism to continue the operant, or event that occurred right before the stimulus. If an operant is no longer followed by a reinforcer, extinction of the operant behavior will occur.
Operant conditioning chamber or “Skinner Boxes”
- rats would press on a bar to receive a food ( positive reinforcement ), or could be set up to give an electric shock ( negative reinforcement ).
- pigeons would peck to receive food if a light was on, but not receive food when a light was off.
Extinction of the operant behavior occurs when you stop giving the rat a food pellet as a reward for pushing the pedal.
Cumulative recorder –records the rate of response of the animal in the operant conditioning chamber
Air Crib – a crib that maintained constant temperature and humidity, easy to clean.
Continuous Reinforcement – every time the rat does the correct behavior, it is reinforced with food. Fixed Ratio Schedule – there is a fixed ratio between correct behaviors and reinforcement, i.e., 5 pedal pushes to one food pellet. Fixed Interval Schedule – rat can push the pedal at least once or possibly many more of times per every 30 seconds, but will get only one food pellet. Variable Schedules – variable ratio means you change the amount of pedal pushes needed to receive the food pellet, and variable interval means you change the time period.
Shaping can be used to help an animal to behave in a manner that it would never do in its ordinary daily patterns.
Shaping occurs when a reward is given if the animal does a behavior that is even slightly close to the desired behavior. Then, as the animal continues to exhibit the behavior that closer and closer resembles the desired action, rewards are given. Eventually, the desired behavior will exist. (ie. Pigeons that bowl or play ping pong.)
Think Like a Behaviorist
1. In groups of 3 or 4 develop a behaviorist theory of learning.
2. Compare and contrast your behaviorist theory of learning with an earlier learning theory developed in class last week.
Behaviorism in the Math Classroom
3. In your groups, give specific examples of how behavior theories are applied to the learning of mathematics?
Robert Gagne 1916 - 2002
Robert M. Gagne
Types of Learning Outcomes: Gagne identified several types of learning as behaviors students demonstrate after acquiring knowledge:
Intellectual Skills (such as Problem solving, Higher order rules, Defined concepts, Concrete concepts, and Discriminations)
Learning is a process; you must know and understand lower level skills before advancing to higher level skills. Therefore to teach a skill a teacher must first identify its prerequisite skills and make sure that the students posses them.
It may be that some theoretical basis will one day be proposed to replace the “common- sense logic” which now underlies the designing of sequences of topics for courses. The idea of the “spiral curriculum” (Bruner, 1960, p. 52), for example, proposes that content topics be systematically reintroduced at periodic intervals. Two purposes areas served by such a scheme: First, the previously learned knowledge of the topic is given a review, which tends to improve retention. A second the topic may be progressively elaborated when it is reintroduced leading to broadened understanding and be explicated in detail, but it appears to hold much promise for future curriculum design efforts. (Gagne, 1974)

The 9 Events of Instruction:
These guidelines will allow teachers to reach optimal conditions of learning:
Informing the learner of the objective
Stimulating recall of prerequisite learning
Presenting new material
Providing learning guidance
Providing feedback about correctness
Enhancing retention and recall
Pros and Cons of Behaviorism
Pro- Observable behavior is observable and measurable. We can infer whether changes have been made in student’s understanding from behavioral change.
Con- Some of our most important goals for students learning involve changes in internal (cognitive, affective) things which cannot be directly observed.
Pros and Cons of Behaviorism
Pro- It is easily implemented. Such things as positive verbal reinforcement, or that look of “I’m tired of your nonsense” take little time or effort and usually bring about the desired behavior quickly.
Con- It has its limits. Michael Shayer and Philip Adey made the observation: “In two studies it was found that no evidence of formal thinking capacity could be found in children under the age of 10, no matter how clever they were.”(Shayer & Adey ,1981) – By clever they mean measured IQ scores in the 160 range.
Behaviorism in a Rural Education Context
In rural school districts, the center of the cultural environment for the community as well as the students is the school. The school is influential in community values.
Corporal punishment is more prevalent in rural areas. “Corporal punishment in public schools is indeed legal in Alabama, Arizona, Arkansas, Colorado, Delaware, Florida, Georgia, Idaho, Indiana, Kansas, Kentucky, Louisiana, Mississippi, Missouri, New Mexico, North Carolina, Ohio, Oklahoma, Pennsylvania, South Carolina, Tennessee, Texas, and Wyoming (Starr, 2002)
