Conditioning and Learning

"Learning, acquiring knowledge or developing the ability to perform new behaviors. It is common to think of learning as something that takes place in school, but much of human learning occurs outside the classroom, and people continue to learn throughout their lives." (Gregory, 1961) Conditioning is the term used to designate the types of human behavioral learning. Since the 1920s, conditioning has been the primary focus of behavior research in humans as well as animals. There are four main types of conditioning: •Classical Conditioning

•Operant Conditioning
•Multiple-Response Learning
•Insight Learning

Conditioning and Learning
Classical Conditioning
"Classical conditioning, also called associative learning, is based on stimulus-response relationships. A stimulus is an object or situation that elicits a response by one of our sense organs, like how a bright light makes us blink. Associative learning allows us to associate two or more stimuli and change our response to one or more of them as a result of simultaneous experience." (Moore, 2002) "According to classical conditioning, learning occurs when a new stimulus begins to elicit behavior similar to the behavior produced by an old stimulus. Studies into classical condition began in the early 1900s by the Russian physiologist Ivan P. Pavlov." (Klein, 1998) Pavlov trained dogs to salivate in response to two stimuli: noise or light, and food or a sour solution. The dogs' salivation is automatically elicited by the food and sour solution, so these were called the unconditional stimulus. However, when the noise or light (conditional stimulus) was repeatedly paired with the food or sour solution over an extended period of time, the dogs would eventually salivate at the noise or light alone. This is a prime example of a conditioned response. Unconditional stimuli, such as the food and sour solution, allow the learning to occur, while also serving to reinforce the learning. Without an unconditional stimulus in his experiment, Pavlov could not have taught the dogs to salivate at the presence of the noise or light.

Conditioning and Learning

Classical conditioning is particularly important in understanding how people learn emotional behavior. For example, when we develop a new fear, we have learned to fear a particular stimulus, which has been combined with another frightening stimulus.

Operant Conditioning
"Operant conditioning is goal-directed behavior. We learn to perform a particular response as a result of what we know will happen after we respond." (Blackman, 1975) For example, a child may learn to beg for sweets if the begging is usually successful. There is no single stimulus that elicits the begging behavior, but instead it occurs because the child knows that this action may result in receiving treats. Every time the child receives sweets after begging, the behavior is reinforced and the tendency of the child to beg will increase. During the 1930s, American psychologist and behaviorist Burrhus F. Skinner performed several important experiments into operant conditioning. Using what is now termed a Skinner Box, he trained rats to press levers to receive food. A hungry rat would be placed in a box containing a special lever attached to concealed food. At first the hungry rat would wander around the box, investigating its surroundings. Eventually it would accidentally press the lever thereby releasing a food pellet into the box. At first the rat would not show any signs of associating the two events, but over time its exploring behavior becomes less random as it begins to press the lever more Conditioning and Learning

often. The food pellet reinforced the rat's response of pressing the lever, so eventually the rat would spend most of its time just sitting and pressing the lever. This type of learning is based on the idea that if a behavior is rewarded, the...
