Socially-mediated reinforcement involves the delivery of reinforcement that requires the behavior of another organism. For example, another person is providing the reinforcement. The Premack principle is a special case of reinforcement elaborated by David Premack , which states that a highly preferred activity can be used effectively as a ...
Reinforcement learning (RL) is an interdisciplinary area of machine learning and optimal control concerned with how an intelligent agent should take actions in a dynamic environment in order to maximize a reward signal. Reinforcement learning is one of the three basic machine learning paradigms, alongside supervised learning and unsupervised ...
A neurochemical process involving dopamine has been suggested to underlie reinforcement. When an organism experiences a reinforcing stimulus, dopamine pathways in the brain are activated. This network of pathways "releases a short pulse of dopamine onto many dendrites , thus broadcasting a global reinforcement signal to postsynaptic neurons ."
Skinner's theory of operant conditioning played a key role in helping psychologists understand how behavior is learned. It explains why reinforcement can be used so effectively in the learning process, and how schedules of reinforcement can affect the outcome of conditioning.
Reinforcement occurs when the consequence of a behavior makes it more likely for that behavior to occur in the future. Reinforcing consequences can be either positive, where something preferred is added, or negative, where something aversive is removed. [63] Reinforcement is the key element in operant conditioning and most behavior change programs.
Reinforcement, a key concept of behaviorism, is the primary process that shapes and controls behavior, and occurs in two ways: positive and negative. In The Behavior of Organisms (1938), Skinner defines negative reinforcement to be synonymous with punishment, i.e. the presentation of an aversive stimulus
Social learning theory is a theory of social behavior that proposes that new behaviors can be acquired by observing and imitating others. It states that learning is a cognitive process that takes place in a social context and can occur purely through observation or direct instruction, even in the absence of motor reproduction or direct reinforcement.

Shaping is a conditioning paradigm used primarily in the experimental analysis of behavior.The method used is differential reinforcement of successive approximations.It was introduced by B. F. Skinner [1] with pigeons and extended to dogs, dolphins, humans and other species.
