Emotion: How does your mood affect your perception of things?
Perception is selecting and processing sensory information. Yet, through processing, we may alter the interpretive qualities of what we perceive. Emotion is one of the fallibilities of perception. Our emotional state arises because of a particular series of events or because we are under the influence of drugs or alcohol. Our mood or emotional state triggers perceptual expectations and we then become accustomed to perceiving things in accord to our mood. Thus, mood does in fact affect the way we perceive things.
For example, when a person is in a very happy mood, a state where that person can say “this the happiest moment of my life,” this person would certainly perceive things more optimistically, positively and joyfully than a person who is in a very bad mood who will certainly perceive things pessimistically, negatively and angrily. I have personally experienced a similar example mentioned above. For instance, the day I learned that I was going back to school (after not attending school for a year) I was so happy and hungry for knowledge. I was so excited and eager to learn new things and do any of the homework that will be assigned to me. But as days passed and I became fed up and tired of school, I was very annoyed at the fact that teachers were bombarding us, the students, with homework and assignment (this is exactly what I feel right now).
