Answer:
The answer is: false alarm
Explanation:
The "Signal Detection Theory" is <u>one of the theories used when it comes to psychology (particularly, perception and sensation</u>). When a person faces a <em>situation (stimulus or signal)</em> that he thinks is confusing, he can make a decision out of it.
If signals are present, this allows the person to decide whether it is present or absent. So, the outcome are hits or misses. When a signal is not present, the person still can decide whether it is present or absent. So, the outcome are "false alarms"<em> (if he decides its present) </em>or "correct rejection" <em>(if he decides its absent).</em>
In the situation above, Peter hasn't been to India. Thus, he doesn't know how it is to live in India nor the weather and culture in the country. So, in this situation, the signal is not present. However, Peter decides that the signal is present <em>(according to his perception)</em> and thus, he continued to go to India. However, he was disappointed with his decision. This kind of outcome is called "false alarm."
Thus, this explains the answer.
