Thorndike's Law of Learning

Edward L. Thorndike in the early 1900's postulated several "Laws of Learning," that seemed generally applicable to the learning process. Since that time, other educational psychologists have found that the learning process is indeed more complex than the "laws" identified. However, the "laws" do provide the instructor with insight into the learning process that will assist in providing a rewarding experience to the trainee. 

The laws that follow are not necessarily stated as Professor Thorndike first stated them. Over the years, they have been restated and supplemented, but, in essence, they may be attributed to him. The first three are the basic laws: the law of readiness, the law of exercise, and the most famous and still generally accepted, the law of effect. The other three laws were added later as a result of experimental studies: the law of primacy, the law of intensity, and the law of recency.

Operant Cocditioning

Operant conditioning can be defined as a type of learning in which voluntary (controllable; non-reflexive) behavior is strengthened if it is reinforced and weakened if it is punished (or not reinforced). 

Note: Skinner referred to this as Instrumental Conditioning/Learning 

A. The most prominent figure in the development and study of Operant Conditioning was B. F. Skinner 

 History: 

a) As an Undergraduate he was an English major, then decided to study Psychology in graduate school. 

b) Early in his career he believed much of behavior could be studied in a single, controlled environment (created Skinner box - address later). Instead of observing behavior in the natural world, he attempted to study behavior in a closed, controlled unit. This prevents any factors not under study from interfering with the study - as a result, Skinner could truly study behavior and specific factors that influence behavior. 

c) during the "cognitive revolution" that swept Psychology (discussed later), Skinner stuck to the position that behavior was not guided by inner force or cognition. This made him a "radical behaviorist". 

d) as his theories of Operant Conditioning developed, Skinner became passionate about social issues, such as free will, how they developed, why they developed, how they were propagated, etc.

Classical Conditioning

Classical Conditioning is the type of learning made famous by Pavlov's experiments with dogs. The gist of the experiment is this: Pavlov presented dogs with food, and measured their salivary response (how much they drooled). Then he began ringing a bell just before presenting the food. At first, the dogs did not begin salivating until the food was presented. After a while, however, the dogs began to salivate when the sound of the bell was presented. They learned to associate the sound of the bell with the presentation of the food. As far as their immediate physiological responses were concerned, the sound of the bell became equivalent to the presentation of the food.

Definition and Types of Learning

Learning is often defined as a relatively lasting change in behavior that is the result of experience. Learning became a major focus of study in psychology during the early part of the twentieth century as behaviorism rose to become a major school of thought. Today, learning remains an important concept in numerous areas of psychology, including cognitive, educational, social, and developmental psychology. 

And also learning can be defined as a relatively durable change in behavior or knowledge that is due to experience.
