Perception is the process of receiving and interpreting sensory information based on an individual's senses and life experiences. It involves becoming aware of one's environment through the five senses of touch, taste, sight, sound, and smell. Psychological factors like social interactions, events, and media shape perceptions by influencing attitudes, biases, expectations, and self-image. Accurately perceiving others is important for effective communication because perception can differ between individuals based on their unique experiences.
