Sign

__**Sign**__

Signs are used as memory aids to help us remember certain ideas, persons, places, or things. Vygotsky (1978) states that "sign operations are the product of specific conditions of social development." According to Vygotsky (1978) a sign follows the behavioral formula (S--->R) of a stimulus(S) creating a response(R), however, a sign requires an intermediate link(X) between the stimulus and response(S-->X-->R). Where the sign is the intermediate link. Vygotsky (1978) states two requirements of the "sign" formula, 1) the learner must be actively engaged and 2) the sign acts on the person, not the environment.
