Answer:
The correct answer would be, Motives.
Explanation:
Derek is a student who want to win the student of the year award and he wanted it so badly that when the name of the winner was announced, he was convinced that he hears his name. But in actual, it was not the case. His behavior illustrates how motives can affect perception. He wanted to hear his name, because he wanted that award so desperately, so he perceived that his name was announced, whereas the name of another student was announced. Unsatisfied needs and motives stimulate individuals to an extent that they have a high influence of their motives on the perception. The attitude of the person affects his perception.
