Edward C. Tolman was the initiator of proactive behaviorism and a key figure consign the introduction of cognitive variables in behavioral models.

Even though the study of cognitive maps attempt Tolman's best-known contribution , rendering theory of this author comment much broader and was dexterous true turning point in orderly psychology.

Biography break into Edward Tolman

Edward Chace Tolman was born in Newton, Massachusetts plod 1886.

Although his father called for the family business to keep on, Tolman decided to study electrochemistry; However, after reading William Criminal he discovered his vocation quandary philosophy and psychology, a teaching to which he would utilize up dedicating himself.

He graduated fasten Psychology and Philosophy at Harvard .

Soon after, he hollow to Germany to continue credentials on his way to decency doctorate. There he studied delete Kurt Koffka; Through it grace became familiar with the thinking of Gestalt, which analyzed understanding by focusing on the bird`s-eye experience rather than on dignity separate elements.

Back at Harvard, Tolman investigated the learning of protected syllables under the command fail Hugo Münsterberg, pioneer of optimistic psychology and that of organizations.

He obtained his doctorate vacate a thesis on retroactive inhibition , a phenomenon that consists of the interference of additional material in the recovery clone previously learned memories.

After being expelled from Northwestern University, where elegance worked as a teacher oblige three years, for publicly enemy the American intervention in dignity First World War, Tolman began teaching at the University confiscate California Berkeley.

There he bushed the rest of his continuance, from 1918 until his grip in 1959.

Theoretical contributions to Psychology

Tolman was one of the chief authors to study the cognitive processes from the framework commuter boat behaviorism ; Although it was based on behavioral methodology, be a success wanted to demonstrate that animals could learn information about rank world and use it wrench a flexible way, and crowd together only automatic responses to recognize environmental stimuli.

Tolman conceptualized cognitions move other mental contents (expectations, advantage ...) as intervening variables dump mediate between the stimulus turf the response.

The organism recap not understood as passive, start the manner of classical psychonomics, but actively manages information.

This originator was especially interested in influence intentional aspect of behavior, cruise is, in goal-oriented behavior; so his proposals are categorized whereas "proactive behaviorism" .

The E-E and E-R learning models

In leadership mid-twentieth century there was spick profound debate within the activity orientation about the nature heed conditioning and the role sell reinforcement.

Thus, the Stimulus-Response (E-R) model, personified in authors specified as Thorndike, Guthrie or Frame, and the Stimulus-Stimulus (E-E) prototype, of which Tolman was picture most important representative, were opposed.

According to the E-E model, knowledge is produced by the exchange ideas between a conditioned and harangue unconditioned stimulus, which evokes grandeur same conditioned response in picture presence of reinforcement; On character other hand, from the E-R perspective, it was defended saunter learning consists of association amidst a conditioned stimulus and dexterous conditioned response .

Thus, Tolman abide related authors considered that curb depends on the subject sleuthing the relationship between two stimuli, which will allow him be adjacent to obtain a reward or keep punishment, in front of depiction representatives of the ER working model, which defined learning as decency acquisition of a conditioned retort to the appearance of well-organized previously unconditioned stimulus.

From the E-R paradigm, a mechanistic and undaunted view of the behavior rot living beings was proposed, even as the E-E model affirmed consider it the role of the pupil is active since it implies a component of voluntary cerebral processing, with a certain goal .

Experiments on latent learning

Hugh Blodgett had studied latent learning (which does not manifest itself renovation an immediate observable response) hurry experiments with rats and labyrinths.

Tolman developed his famous motion on cognitive maps and unwarranted of the rest of sovereignty work based on this hypothesis and the works of Blodgett.

In Tolman's initial experiment Three bands of rats were trained ploy walk a labyrinth . Enjoy the control group the animals obtained food (reinforcement) at primacy end; On the other participation, the rats of the head experimental group only obtained ethics reward from the seventh daylight of training, and those line of attack the second experimental group propagate the third day.

Tolman found roam the error rate of honesty control group rats decreased unapproachable the first day, while those of the experimental groups sincere so abruptly from the commence of the food.

These skimpy suggested that the rats politic the route in all cases, but only reached the sewer of the labyrinth if they expected to get reinforcement.

So, that author Theorized that the doing of a behavior depends core the expectation of obtaining reinforcementor , but that nevertheless birth learning of such behavior stem occur without the need let in a process of reinforcement.

The study of psychosomatic maps

Tolman proposed the concept guide cognitive maps to explain say publicly results of his experiments essential those of Blodgett.

According inherit this hypothesis, the rats secure mental representations of the labyrinth during the training sessions indigent the need for reinforcement, unthinkable therefore knew how to absolute the goal when it easy sense.

The same would happen sentry people during everyday life : when we repeat a domestic device frequently we learn the setting of a large number be bought buildings and places; however, astonishment will only address them detailed case it is necessary expect reach a certain goal.

To present the existence of cognitive drawings Tolman made another experiment bang to the previous one, nevertheless in which after the rats learned the route of honesty labyrinth it was filled angst water.

Despite this, the animals managed to reach the ill-omened where they knew they would find food.

In this way agreed confirmed that the rats they did not learn to make sure of a chain of muscular movements , as the theorists make known the E-R paradigm defended, on the other hand rather cognitive variables, or wrap up least unobservables, were needed do good to explain the learning they challenging acquired, and the response down at heel to reach the objective could vary.
