Miller’s learning Sequences

Miller’s learning Sequences
All learning theories agree  on two basic assumption is explaining personality. First, all bihaviour is learned by the organism in the process of interaction with external stimuli. Second behavior of the individual can be objectively observed. This learning theories were developed in the process of experiments. Experimental psychologists were of the view that learning theory is the most reliable and objective approach to understand personality. Two learning theories of personality are given below :-
a)     S.R. Learning theory of Dollar d & Miller.
b)    Social behaviouristic theory of Bandura & Walter.

Miller’s Learning sequences

This theory is also called reinforcement theory of personality while developing this theory they borrowed basic ideas from psycho analysis & converted them into Hulls theory of reinforcement. According to  them learning theory is the study of circumstances under which a response and a cue become connected. They are joined together in such a way that appearance of the cue the response in a natural manners. The connection between response in a natural manners. The connection between response cue can be strengthened only under certain conditions. The learner is driven to make the response  & rewarded for the response in the presence of the cue. This learning requires four factors ; They are :-

I    Drive :-

It is related to motivation & initiates action on the part of the organism. Drive differs in strength in different organism. The stronger the drive, the more vigorous or persistent will be the behavior. There is a +ve correlation b/w  drive & stimulus also.
The Stronger the stimulus, the greater will be its drive function.
Drives can also be classified into two broad categories.

Primary or inactive drives.

They originate from the physiological needs of the indvl. Such as sex, hunger, thirst etc. They are essential for the survival of the organism. They are most forceful than the secondary drives.

Secondary or acquired drives.

They are acquired from the process of social learning, such as practice, status, affection, approval, money, achievements etc.
They can be termed to stimulus & guides

II   Cue :

It is related to stimulus & guides . The organism for response. Cues (stimuli) are fundamental elements for learning . They may be internal as well as external. They are also distinctive in nature is learned can differentiate them in different situations. Learning of an individual. depends on the perceiving abilities of cues. Thus, it is cue that determines when and where an individual. will respond and what type of response he will make.

III.  Response :

Drive and cue combined together enables the organism to respond. Response is the action of the organism which is the basis for learning. Thus learning will take place, only when appropriate response is produced the strength of S-R1 habit increases with the number of occasion on which S-R have occurred together.

IV. Re-inforcement

When  a response is followed by a reward, the connection between S-R  is strengthened and the possibility of correct response increase. Reinforcement takes place in the presence of a drive. If drive is dead, reinforcement will not work. As far as schedule reinforcement is concerned, immediate reinforcement after the response is more effective than the delayed reinforcement. If an organism is immediately rewarded after the response, he will be able to identify the act for which he has been rewarded.

OTHER PRINCIPLES OF S - R LEARNING

a)                 Extinction :
It is a process of weakening or eliminating previously learned responses. When a response is not rewarded for a number of times, S-R bond weakens and finally no response is exhibited due to the absence of reward. This extinction is not permanent. An
extinguished habit reappears if reward is again given. This is called spontaneous recovery.
b)                Stimulus Generalization :
It is a process in which responses learned from one situation are transferred is a variety of similar situations. The amount of this generalization  depends  on the similarity b/w two similar situation. It ** the horizon of learning. The stronger the drive, the more stimulus generalization will takeplace.

c)  Habit Hierarchy Response

Whatever is learned by the organism becomes the part of his habit if S-R bond is repeated, again and again. Early years of life for a child is important because during these years the child establishes responsed hierarchy for  a great variety of stimulus contexts.

d)  Discrimination

In this process, learned responses are made to particular and appropriate cues in the environment it not to others. This process is very essential for concept formation. Habits are formed by S-R connection in the presence of reinforcement materials.
MERITS
1.                 It is purely objective approach to explain human behaviour
2.                 It emphasises the role of learning from infancy onwards.
3.                 It rejects the concepts of ego and super ego(developed)    by
Freud
4.                 It states that appropriate habits can be framed by appropriate learning conditions
DEMERITS
1.            Learning principles have been derived from the researches conducted in rats , dogs etc under controlled conditions. The application of these principles on human is not a sound approach.
2.            The theory neglects the complexities of human learning . Here cognitive infinitive subjective aspects of human behaviour have been completely ignored .
3.            The theory over emphasizes the importance of environmental factors in shaping the personality and neglects heredity factors all together .

4.            It is a molecular and fragmented approach of studying personality. Human behaviour cannot be predicted in the basis of this theory
