Vygotsky and Pavlov

Vygotsky rejected strict reflexology of Bekhterev, CR of Pavlov, behaviorism of Watson. CR cannot explain higher cortical processes such as language. Instead of stimulus-response, he proposed stimulus -means. Buridano's donkey was an example given -- a donkey between 2 sacks of flour, instead of choosing either, starves of indecision. This is because the 2 stimuli produce "equal and opposite reactions."
