It defines key terms related to perception like sensation, stimulus, and the perception process of receiving stimuli, selecting stimuli, organizing and interpreting to form a response. It also outlines principles of perceptual organization like figure-ground, proximity, similarity and factors affecting perception. It briefly discusses extrasensory perception phenomena like clairvoyance and precognition, noting a lack of confirmation through repeatable research.

10. ExtraSensory Perception
This is otherwise known as sixth sense in common man’s view. Some of
the common phenomena in ESP are clairvoyance, telepathy, meeting
the souls, precognition, psycho-kinesis, reincarnation, etc.
Though research is going on, the researchers are unable to confirm
them, because these experiences are not repeatable for verification. In
many instances they remain as coincidences.
