“Process of acquiring modifications in existing knowledge, habits, or tendencies through experience, practice, or exercise. Learning includes associative processes, discrimination of sense-data, psychomotor and perceptual learning, imitation, concept formation, problem solving, and insight learning. Animal learning has been studied by ethologists and comparative psychologists, the latter often drawing explicit parallels to human learning. The first experiments concerning associative learning were conducted by Ivan Pavlov in Russia and Edward Thorndike in the U.S. Critics of the early stimulus-response (S-R) theories, such as Edward C. Tolman claimed they were overly reductive and ignored a subject’s inner activities. Gestalt-psychology researchers drew attention to the importance of pattern and form in perception and learning, while structural linguists argued that language learning was grounded in genetically inherited ‘grammar.’ Developmental psychologists, such as Jean Piaget, highlighted stages of growth in learning. More recently, cognitive psychologists have explored learning as a form of information processing, while some brain researchers, such as Gerald Edelman, have proposed that thinking and learning involve an ongoing process of cerebral pathway building. Related topics of research include attention, comprehension, motivation, and transfer of training.”
