Learning is acquiring new, or modifying existing, knowledge,behaviors,skills,values, or preferences and may involve synthesizing different types of information. The ability to learn is possessed by humans, animals and some machines. Progress over time tends to follow learning curves. Learning is not compulsory; it is contextual. It does not happen all at once, but builds upon and is shaped by what we already know. To that end, learning may be viewed as a process, rather than a collection of factual and procedural knowledg e. Human learning may occur as part ofeducation,personal development , schooling, or training. It may begoal-orientedand may be aided bymotivation. The study of how learning occurs is part ofneuropsychology ,educationa l psychology,learning theory, andpedagogy.Learning may occur as a result ofhabituationorclassical conditioning, seen in many animal species, or as a result of more complex activities such as play, seen only in relatively intelligent animals. [1][2] Learning may occurconsciouslyor without conscious awareness . There is evidence for human behavioral learning prenatally, in whichhabituationhas been observed as early as 32 weeks into gestation, indicating that thecentral nervous systemis sufficiently developed and primed for learning and memory to occur very early on in development . [3] Play has been approached by several theorists as the fir st form of learning. Children play, experiment with the world, learn the rules, and learn to interact. Vygotskyagrees that play is pivotal for children's development, since they make meaning of t heir environment through play. The context of conversation based on moral reasoning offers some proper observations on the responsibilities of parents.
