Consciousness the awareness of internal and external stimuli. William james consciousness is continually changing stream of mental activity (stream of consciousness) Freud argues that people"s feelings and behaviour are influenced by unconscious needs, wishes, and conflicts that lie below the surface of conscious awareness. Controlled processing judgements or thoughts that we exert some control over, that we intent to occur. Automatic processing its effects happen without our intentional control or effort. Consciousness doesn"t come from any distinct brain structure, but from activity distributed in neural pathways. Electroencephalograph (eeg) a device that monitors the electrical activity of the brain over time by means of recording electrodes attached to the surface of the scalp. Human brain-wave activity divided into four principal bands (based on frequency) Beta (13-24 cps) normal waking thought, alert problem solving. Alpha (8-12 cps) deep relaxation, blank mind, meditation. Delta (under 4 cps) deep sleep. Biological rhythms periodic fluctuations in physiological functioning.
