2. According to him learning takes place by trial and
error. In learning the learner selects a correct
response out of a large number of possible ones
and connects it with the appropriate stimulus.
Learning by this method is called trial and error
learning theory.
3. Thorndike formulated his theory, based on his
experiments conducted on his cat in the puzzle box.
The door of the box could be opened by pulling the
strings inside the box. A fish was kept outside. The cat
was tried to come out of the box by squeezing,
jumping, biting etc. As the experiment was repeated
for several times the wrong movements decreased and
in the end the cat was able to open the door in a single
trial.
Experiment
7. 1.Motive or drive
Drive is a tension state resulting from
needs. Where there is drive or motive
there is learning. In the present
experiment drive was hunger.
8. 2.Stimulus or goal
It is the casual factor for activity. In the
present experiment, food is the stimulus.
To get the food by getting out of the box is
the goal.
9. 3. Responses
The cat makes a number of varied types of
responses like scratching, pulling etc. The
responses which lead to the goal known as
satisfying responses. The responses which do
not lead to the goal is known as annoying
responses.
11. As a result of random movements, the
cat, by chance, succeeded in opening
the door.
5. Chance success
12. 6. Selection of proper movement
Gradually the cat selected the proper
way of pulling the string out of its
random movements.
13. 7. Fixation
At last, the cat learned the proper way of
opening the door by eliminating all the incorrect
responses and fixing only right response. Now
the cat was able to open the door without any
error.
16. Law of readyness
The law states that “when any conduction unit is
ready to conduct, for it to conduct is satisfying.
When any conduction unit is not ready to
conduct, for it to conduct is annoying. When any
conduction unit is ready to conduct, for it not to
conduct is also annoying.”
17. Law of effect
The law stated that “any behavior that is followed
by pleasant consequences is likely to be repeated,
and any behavior followed by unpleasant
consequences is likely to be stopped.”
18. Law of exercise
The law states that repeated exercising of a
response strengthens its connection with the
stimulus. And connection is weakened through
failure of practice.
19. Law of exercise
1. Law of use: 2. Law of disuse:
With practice, the
connection is strengthened.
When the practice is
discontinued, connection is
weakened.
21. Law of multiple response
The law implies that confronted with a new
situation, the organism response in a variety of
ways before arriving at the correct response.
22. Law of attitude
Learning is guided by the attitude of the organism
towards the task. The learner performs the task
properly, if he has developed a healthy attitude
towards the task.
23. Law of analogy
An individual response to a new situation on the
basis of the responses made by him in similar
situation in the past, that is the organism makes
responses by analogy.
24. Law of associative shifting
The law states that “any response may elicited
from the learner in associated with any situation
to which he is sensitive.”
