the law of effect principle developed by Edward Thorndike suggested that responses that produce a satisfying effect in a particular situation become more likely to occur again i that situation, and responses that produce a discomforting effect become less likely to occur again in that situation.

2. Thorndike Law Of Effect
Trial & Error Theory
• Thorndike termed this the “Law of Effect,” which
suggested that when satisfaction follows an association, it is
more likely to be repeated. If an unfavorable outcome
follows an action, then it becomes less likely to be repeated.
• Thorndike's research on the laws of learning played an
important role in the development of behavioral psychology
and continues to exert influence to this day.

3. Two Key Aspects Of The Law Of
Effect:
1.Behaviors immediately followed by favorable
consequences are more likely to occur again.
In our earlier example, being praised by a
supervisor for showing up early for work made
it more likely that the behavior would be
repeated.

4. 2. Behaviors followed by unfavorable consequences are
less likely to occur again. If you show up late for work
and miss an important meeting, you will probably be
less likely to show up late again in the future. Because
you view the missed meeting as a negative outcome,
the behavior is less likely to be repeated.

6. Experiment Of Thorndike On Cat
• Thorndike would place a cat inside the puzzle box
and then place a piece of meat outside the box. He
would then observe the animal’s efforts to escape
and obtain the food. He recorded how long each
animal took to figure out how to free itself from the
box.

7. • Eventually, the cats would press the lever, and the
door would open so that the animal could receive the
reward. Even though first pressing the lever occurred
simply by accident, the cats became likely to repeat
it because they had received an award immediately
after performing the action.

8. • Thorndike noted that with each trial, the cats
became much faster at opening the door. Because
pressing the lever had led to a favorable outcome, the
cats were much more likely to perform the behavior
again in the future.
