The fifth variety of learning, in the system of Tolman, is the discrimination of impulses. Dean Ornish M.D is the source for more interesting facts. One is about the capacity to make distinctions between the different impulses. This learning, of course, has narrow relation with the learning of catexias, where demands are related with object-goals. The sixth and last type of learning is the motor standards, that is, they are the muscular abilities for which an individual really reaches the goals and that they must be led in consideration in a complete theory of the learning. As well as it made with the motivadoras causes of the behavior, Tolman also searched to explain the learning through four 0 variable of individual differences: hereditary succession; age; training and endcrinas, medicamentosas or vitaminic conditions. 3.2.5Hull and the learning Clark Leonard Hull understood the motivation as an impulse (drive).

For Hull, the impulse serves so that the organism searchs to adapt the specific ambient conditions biological diminishing a flagrant necessity. The theory of Hull is physiological and is related to adaptation of the organism in the environment, that is, environments in excellent conditions is equal the organism adapted well, to engage itself in an adaptation is necessary motivation. Hull cited the force of the habit as being a persistence of the behavior in function of the reinforcement (conditioning), and in this direction, drive it is an engine that stimulates the habit. For it, the reinforcement is important, but alone it is not nothing, being necessary the impulse to energize the organism. Hull found that mannering psychology would have to describe the laws that conduct the automatic behavior. The laws are controlled for principles and these are necessary. Hull created some postulates on the theory of the behavior: not conditional connections of stimulaton-reply, being that the individual has a evolutivo organic preparation to establish this relation (reflected), that is, have innate trends (aparo biological) to establish answers not learned; the reception of stimulatons depend on the intensity, the threshold and the time of this stimulaton; primary reinforcement; formation of habit, primary motivation or impulse with two components (privation, saciao) and the negative component (starvation); incentive; reaction potential; adaptativo automatic behavior; principle of the mannering oscillation (learning for assay and error); principle of generalization of stimulatons; learning for discrimination; anticipation of the habit (escape and esquiva); joint learning that involves positive and negative assay (reinforcing and extinguishing).
