Learning theories are conceptual frameworks in which knowledge is absorbed, processed, and retained during learning. Cognitive, emotional, and environmental influences, as well as prior experience, all play a part in how understanding, or a world view, is acquired or changed and knowledge and skills retained.
Behaviorists look at learning as an aspect of conditioning and will advocate a system of rewards and targets in education. Educators who embrace cognitive theory believe that the definition of learning as a change in behavior is too narrow and prefer to study the learner rather than their environment and in particular the complexities of human memory. Those who advocate constructivism believe that a learner's ability to learn relies to a large extent on what he already knows and understands, and the acquisition of knowledge should be an individually tailored process of construction. Transformative learning theory focuses upon the often-necessary change that is required in a learner's preconceptions and world view.
Outside the realm of educational psychology, techniques to directly observe the functioning of the brain during the learning process, such as event-related potential and functional magnetic resonance imaging, are used in educational neuroscience. As of 2012[update], such studies are beginning to support a theory of multiple intelligences, where learning is seen as the interaction between dozens of different functional areas in the brain each with their own individual strengths and weaknesses in any particular human learner.
Plato (428?–347 BC) proposed the question: How does an individual learn something new when the topic is brand new to that person? This question may seem trivial; however, think of a human like a computer. The question would then become: How does a computer take in any factual information without previous programming? Plato answered his own question by stating that knowledge is present at birth and all information learned by a person is merely a recollection of something the soul has already learned previously, which is called the Theory of Recollection or Platonic epistemology. This answer could be further justified by the paradox of if a person knows something, then they will not need to question it and if a person does not know something, then they will not know to question it at all. Plato says that if one did not previously know something, then they cannot learn it. He describes learning as a passive process, where information and knowledge are ironed into the soul over time. However, Plato's theory elicits even more questions about knowledge: If we can only learn something when we already had the knowledge impressed onto our souls, then how did our souls gain that knowledge in the first place? Plato's theory can seem convoluted; however, his classical theory can help us understand knowledge today still.
