Final answer:
Parapsychology is the study of events without known psychological, physical, or biological explanations, covering phenomena like clairvoyance and telepathy.
Step-by-step explanation:
The study of events that cannot be explained by known psychological, physical, or biological mechanisms is referred to as Parapsychology. This includes phenomena like clairvoyance, psychokinesis, and telepathy which don't have a readily observable scientific basis. Psychology is a vast field that explores the scientific study of the mind and behavior, utilizing the scientific method and hypotheses backed by evidence to explain a wide variety of phenomena. In this case, Parapsychology is concerned with those aspects of the 'occult' or supernatural that lie outside the explanations provided by traditional psychological theories.
