Comparing the Unconscious and Consciousness Consciousness and unconscious are two psychological terms that are commonly used in this field of study. Their importances mainly appear when psychologists deal with their patients because they will surely think about these two terms. To understand these two terms we must know their definitions. This step can enable us to recognize the difference between them. Consciousness is a psychological condition defined by the English philosopher John Locke as "the perception of what passes in a man's own mind." While unconscious in psychology is the aspect of mental life that is separated from immediate consciousness and is not subject to recall at will. The history of consciousness is…show more content…

In behaviorist psychology, derived primarily from work of the American psychologist John B. Watson in the early 1900s, the concept of consciousness was irrelevant to the objective investigation of human behavior and was doctrinally ignored in research. Neobehaviourists, however, adopted a more liberal posture toward mentalistic states such as consciousness. Neurophysiological mechanisms that consciousness depends on the function of the brain has been known from ancient times. Although detailed understanding of the neural mechanisms of consciousness has not been achieved, correlations between states of consciousness and functions of the brain are possible. Levels of consciousness in terms of levels of alertness or responsiveness are correlated with patterns of electrical activity of the brain waves recorded by an electroencephalograph. During wide-awake consciousness the pattern of brain waves consists of rapid irregular waves of low amplitude or voltage. In contrast, during sleep, when consciousness can be said to be minimal, the brain waves are much slower and of greater amplitude, often coming in periodic bursts of slow waxing and waning amplitude. Both behavioral levels of
