Document Summary

In psychology, it often refers to a person"s subjective awareness of internal and external stimuli, including awareness of internal and external stimuli, including thoughts, perceptions, experiences, and self-awareness.

Psychological variations, such as sensory deprivation, hypnosis, mindfulness meditation: what are some normally occurring variations of consciousness? (sleep and dreams) Pace of 90 minutes: approximately every 90 minutes we pass through ve stages of sleep. These stages are associated with di erent brain waves: vary in frequency, amplitude and regularity, are measure with an electroencephalogram (eeg) Awake and active: beta waves: high frequency, low amplitude, these waves are often irregular waves. Awake and calm: alpha waves: lower frequency and higher amplitude than beta waves, more regular than beta waves. Theta waves: lower frequency and larger amplitude than alpha waves. Delta waves: very low frequency, high amplitude and regular.
