Psychology -> Altered States of Consciousness: Measurement of Physiological Responses

Measurement of physiological responses


Measurement of physiological responses which can indicate different states of consciousness: electrical activity of the brain and other physiological responses, including heart rate, body temperature and galvanic skin response.

A state of consciousness cannot be observed or measured directly. However, psychologists use various tools to detect changes in levels of consciousness. The electroencephalograph (EEG) is used to measure the electrical activity of the brain. Changes in brain wave patterns provide psychologists with information about a person's level of consciousness. The EEG has proven most useful in the identification of the different stages of sleep.
