Theory Of Learning


Tolman, the foremost critic of Watson’s Muscle twitchism was granted his PhD in 1915 from Skimmer’s alma mater, Harvard except for three years of teaching at Northwestern University, he spend most of his academic career at the University of California at Berkeley, Until his resignation in protest against pressure to sign a loyalty oath in 1950.
He then taught from 1950 to 1953 at the university of Chicago and at Harvard. He acknowledged many sources for his ideas, including his Harvard professor, Edwin holt, as well as Kurt Lenin and his student researchers at Berkeley.

Tolman Experiments:-


He used mouse for his experiment, for this purpose. He divided then in three groups. They were all hungry. He left free a group into maze. They walk here and there. When they crossed the maze no reward given them. So it is clear that the first group has no method to learn. On the other hand when second group crossed the maze a reward given them. So they learn come out from maze very fast.
First group exercise was continues in maze. It shows that they are not learning some thing. This experiment continued for then days how ever after then day when a reward given them they tried their best to learn come out from maze.
After some trials their standard it like second group. There was also a third group of hungry mouse.
This group runs here and there in maze but this group comes out from maze no reward given them. This group mistakes again and again.


He dedicated a book published in 1932 to the white rat. In 1922 Tolman announced his purposive behaviorism approach to learning and continued to develop this unique approach throughout his long academic career. His tykes were difficult He wished to preserve the objectivity of behaviors movements by rejecting the introspections method.

He also wanted to concentrate on measurable external stimuli and responses without embracing the –brittle excesses of the Watson won movements. While adopting the behaviorist practice of using animal models to test generalized learning principles, Tolman differed from connectionist behaviorists in two critical ways. First he avoided the prevailing practice of treating hypothesized internal entities as hypothetical constructs or physical realities, which would be discovered in time, Instead. He referred to his units of cognitions and the like as interviewing variables, or pure also tractions, rather than as near logical mechanisms. This both allowed this theory to escape the fate of Pavlov’s premature neurologizing and let him explain very complex pheneoumer in easily understand terms.

Second, while retaining the behaviorist emphasis on experience with external stimuli as the primary cause of learning. Tolman rejected the bonding of stimuli, or stimuli and various types as the basic units of the most important types of learning.

In stimulus response theories it is held that what a learner learns is a series of movements. These movements are connected to stimuli either by association in time and space or by reinforcement. In Tolman’s theory however, it is not a series of movements that are learned but signs or expectations. Movement’s successive circumstances never are assumed to be identical.

The learner perceives the nature of the situation and responds in terms., of these perceptions their procreations are assumed to have their neurological correlations, but their nature is now unknown. However Tolman and others have a phrase to express the concept that somewhere in the neurotically structure there is a correlate to the exception of the sign’s expectations and goals structure is still intangible in that it is not yet explicitly described. It is however, an inference based on behavior.



Tolman’s theory is molar in contrast to molecular. By molar, it is simply meaning that its concepts are large and more comprehensive in nature and scope than those if stimulus response theories, which deal with smaller, units. The concept of the atom in physics is molecular, that of the solar system, molar. Whereas stimulus response theorists lent to analyses and reduce behavior to its minimum elements, Tolman’s deal with the patterns, the larger, masses of behavior. He states that these larger connote properties of behavior that will never be reveled by making a molecular approach to behavior. In this sense, Tolman’s concepts are analogous to the gestalt concept that the whole is more than the sum of its parts.

It may be asked in what respect Tolman’s position on purpose differs from Hull’s concept that the learner responds to satisfy a need. Both psychologists accept the view that behavior occurs as a result of a need, reduction; Tolman finds a response being learned in terms of the learned perception of the stimuli. For Tolman’s the stimuli take on a meaning as the result of their perception of the leaner hence they become a sign that behavior will lead to a goal a purpose.

But the terms of the sign Tolman has borrowed from the Gestalt psychologists the concept that the stimuli are papered or organized. He has consequently used the phrase sign Gestalt learning to categories.

Tolman basic data are responses made by the learner in a stimulating situation. This why it can be called a theory of behavior. But Tolman’s interpretations are important. The behavior of those who are learning, according to Tolman’s does not show a behind, mechanistic series of movements are theory responses but rather that an intelligence is at work. Mechanistic theories would lead to the inference that the learned seemed not to be playing any part in his learning.

Types Of Learning:


Tolman revised his theory of learning in 1949 and distinguished sin types of learning.

1.This type of learning explains the final type of positive type of food and drive of hunger.
2.It is a conduction between a positively catered objects and type of sub disturbance of objects.
3.Tiled expectancy develops in the organism when certain environment set up is repeatedly presented to him.


Tiled Elongation Models:


There is a definite relationship between type of drive and mode of response.

Patterns: -


Tolman admits that motor patterns are conditioned.


Major Principles:-



• It accepts behviousim as basis. Main characteristics of behavior are

1. Behavior that is goal directed i.e. it is purposive.
2. Behavior is goal makes use of environmental factors as means or getting at the goal.
3. Behavior consists of the formation of cognitive maps.
4. The organism has a selective preference for the “principles of least effort” for arriving at the goal.
5. Molar Behavior is docile.

• According to Tolman’s behavior depends upon:

1. The need system
2. The belief value matrix.
3. This theory take into consideration at learning is based upon some signs or dues leading to the goal the organism learn not the movement parents, but the sign significant relations.

Tolman’s Purposive Psychology


Just as Hull has made more praise the same psychological concepts that are basic to connectionism, Tolman has given greater order and precision to Gestalt concepts. It has been hard for many persons to accept connectionism or even drive reduction concept of learning because of its seemingly parley mechanistic character. It appears to leave out that which every day experience confirms as being most significant about human behaviour that is that it has purpose. Tolman has come to grips with this problem and has developed a theory of learning that puts purpose or “striving toward a goal” at the heart of it.

Cognitive structure: In stimulus response theories it held that what a learner learns is a series of movements. These movements are connected to stimuli either by association in time and space (contiguity) or by reinforcement. In Tolman’s theory, however it is not a series of movements that are learned but signs or expectations. Movements in successive circumstances can never be assumed to be identical. The learner perceives the nature situation and responds in terms of these perceptions. These perceptions are assumed to have their neurological correlations, but their nature is now unknown. However, Tolman and others have a phrase to express the concept that somewhere in the neurological structure there is a correlate to the perception of the signs, expectations and goals. The phrase, “Cognitive structure”, is still intangible in that it is not yet explicitly described. It is however, an inference based on behaviour.

A molar theory, Tolman’s theory is molar, in contrast to molecular. By molar, it is simply meant that its concepts are larger and more comprehensive in nature and scope than those of stimulus response theories, which deals with smaller units. The concept of the atom in physics is molecular; that of the solar system, Molar. Where as stimulus response theorists lend to analyze and reduce behavior to its minimum elements, Tolman deals with the patterns, the larger masses of behaviour. He states that these larger concepts connote prophetic of behavior that will never be revealed by making a molecular approach to behavior. In this sense, Tolman’s concepts are analogous to the Gestalt concepts that the whole is more than the sum of tits parts.

Sign Learning. It may be asked in what respect Tolman’s position on purpose differs from Hull’s concept that the learner responds to satisfy a need; Both psychologists accepts the view that behavior occurs as a result a need; but whereas Hull finds a response being reinforced, hence learning, by need reduction, Tolman finds a response being learned in terms of the learner’s perception of the stimuli. For Tolman, The stimuli take on a meaning as the result of their perception by the learner; hence they become a sign that behavior will lead to a goal. But the response is learned in terms of the sign. Tolman as borrowed from the Gestalt psychologist the concept that the stimuli are patterned or organized. He has consequently used the phrase sign Gestalt Learning. To categories his theory.

Tolman theory is like Hull’s a behaviour theory. Although it recognizes d purpose, it is not a mental state theory. Tolman’s basic data are responses made by the learner in a stimulating situation. This is why it can be called their behaviour. But Tolman’s interpretations are important. The behaviour or those who are learning according to Tolman, does not shows a blind, mechanistic series of movements or other response but rather that an intelligent is at work. Mechanistic theories would lead to the inference that the learner second not to be playing any part in his learning. It might be implied that the learner is simply a victim of his need and the stimuli that impinge on his sense organs. Tolman would say that the learner is an active participant in the process. Through the process of his brain, albeit that the nature of those processes are still unknown there learner organize the stimuli, attaches meaning the them, and responds accordingly.

Educators have not made a systematic analysis of the application to their work implied in Tolman’s Theory. Yet is obvious that there is a great affinity between Tolman’s position and what teachers do. Teachers do not use such phrase as cognitive structures, Sign gestalts, or molar behaviour. Yet they operate in comply harmony with the meaning of these concepts. As they teach they will say what does this means or signify? What would you expect? Or even the single word, Think perhaps the problem solving types of activities that are often felt to be the best types of learning experiences are highly valid under a purposive psychology of learning.

Lerner Law’s Of Tolman:-


• Learning of an organism depends upon its capacity to learn
• Learning depends upon the nature of the material to be learnt.
• Learning depends upon the manner of presentation of learning material.
Following are the typical learning problems.



PROBLEMS: -

The learning of a task depends upon the capacity of the learner.
• Tolman believes the practice on exercise cannot help a learner in the initial selection of a right response. Mere frequency without belongingness does not establish a connection.
• Stimulus laws which deal with conditions inherent in the material itself such as belongingness of its parts and how well its leads to insightful solution.
• According to Tolman’s motivation does not help in learning something new. It simply encourages the performance as such
• Transfer believes in learning by creative inference. Incentive ideation and so on. Insightful learning is emphasized
• Transfer of training depends upon applicability of the essential relationship perceived by the learner in one situation to some other situation
• Repression a ratio active inhibition caused forgetting to the resistance of cat hexes relationship objective also.

Summary

This theory of learning of result an americal psychologist Edward C.Tolman. He said there is a great role plan of stimulus lerners dicion. Estimate and past experiment in learning. Animals act on target according to whole environment. So according to Tolman learning is not just name of stimulus and mach relationship of reaction to learn. But act of learner effect on remember, select and mental act. It is clear from different studies. The animals do not give reaction blind way. Animal think about environment then serve react.
Tolman was the only major cognitive theorist who demonstrated a credible performance in conducting creative and appropriate rat research perhaps for their reason alone, the behaviorist at the end purposive is app reprobate Tolman began with a broad eclectic theory which grew broader and more eclectic over the years a the concepts of his rivals were digested and incorporated. In general, he was stranger when engaged in a penetrating critique of weakens in the connectionist behaviorist position than in formulating a coherent postulate system of his own his late system of his own his gift of clever experimental design forced the S.R theorists into ever more complex theorizing in their efforts to explain the phenomena he so skillfully demonstrated. In the end, any recognizable from of his theory failed to survive his retirement, in spite of attempts by maccorquodale and mach to pull it together into a strict, Hull types system of postulates and terms; Nonetheless, births and parts of Tolman’s theory appear in various modern theories.Perhaps the greatest of Tolman’s contributions was to make cognitive approaches respectable again and with grace and creative experimentation, to fight against the charges of mentalist raised by the strict behaviorist against cognitive viewpoints. The respect earned by Tolman and Tolman’s followers for their extensive experimental efforts facilitated the acceptance of the more radical cognitive of the gestalt psychologists.
