One of Skinner’s chief contributions to behavior science is said to be the use of the rate of behavior as a dependent variable. How does this approach differ from Thorndike’s studies of chicks running mazes?

Skinner and Thorndike created experiments with animals. Thorndike formulated the following law: "any action that produces a satisfactory effect will be repeated". Thorndike makes cats in problem boxes that, when they behave in a way that disappears like boxes, learn and repeat themselves or move each time they were those only locations.

However, it was Skinner who developed the concept. Operational conditioning describes a correspondence between behavior and consequences. An operator response originated without the presence of an unconditional stimulus, that is, voluntary behavior. It will then be a process through which we learn the answers in order to avoid something unpleasant. But, consequently, the frequency of responses depends on the consequences.

the language of nature was a manifestation from god as he said "let there be light" and there was light the world began to assume visible, comprehensible form.

what ever we know now think of the old vision of creation we can be sure that with out the speaking of word -without language- we would have no science today with its striking power to illuminate the world.
