Psychology describes to clarify realization, actions, and social relations. Empirical psychology is chiefly devoted to describing human experience and performance as it really occur. Since the 1980s, psychology has begun to scrutinize the relationship between consciousness and the brain or nervous system. It is still not clear how these interact: does consciousness decide brain states or do brain states decide consciousness or are both going on in various ways Or, is consciousness some sort of complicated 'illusion' that bears no direct relationship to neural processes? Perhaps to understand this, it is necessary to define "consciousness" and "brain state". An understanding of brain function is more and more being included in psychological theory and practice, particularly in areas such as artificial intelligence, neuropsychological and cognitive neuroscience.

Psychology is an intellectual and functional regulation involving the technical study of mental processes and behavior on Human Being. Psychologists study such phenomenon as cognition, perception, feeling, behavior, activities, and personal affairs.

Self-efficacy is the belief that one is capable of performing in a certain manner to attain certain goals. It is a belief that one has the capabilities to execute the courses of actions required to manage prospective situations.
