PSYC 101: Chapter 5 and Supplemental Readings
Sleep and Consciousness
Nature of Consciousness (11/7)
1) What is consciousness and what does it include? Of what are you aware because of your
consciousness?
- The awareness of internal and extrernal stimulus
1. Awareness of external events
2. Awareness of internal sensations
3. Awareness of your self as the unique being having these experiences
4. Awareness of the thoughts of these experiences
2) Why is it believed there are varying levels of awareness?
Conscious and unconscious processes are different levels of awareness
3) What states of consciousness/levels of awareness are associated with the following brain
wave activities:
a. Beta: normal waking thought, alert problem solving
b. Alpha: deep relaxation, blank mind, meditation
c. Theta: light sleep
d. Delta: deep sleep
Sleep and Waking Cycle (11/7)
1) What physiological changes occur as you descend through the stages (Stages 1-4) of sleep?
In stage 1, breathing and heart rate slow as muscle tension and body temp decline. Going
through 2, 3 and 4, respiration rate, heart rate, muscle tension and body temp decline.
2) What brain wave activity changes occur as you descend through the stages (Stages 1-4) of
sleep? In stage 1, alpha waves dominate EEG activity and right before you fall asleep, theta
waves are emitted.
Slow wave sleep: consists of sleep stages 3 and 4 during which low frequency delta waves
become prominent in EEG readings.
3) REM is an abbreviation for rapid eye movement.
4) What are the characteristics of the REM cycle?
a. Brain wave activity: high frequency beta waves
b. Physiological activity: irregular breathing and pulse rate; minimal body movement
c. Other unique activities: dreaming
5) What is the progression of REM cycles throughout the course of the night?
a. How frequently do they occur? 4 times a night
b. When are they most likely to occur? Later into the night
c. How long do they last? Short at first but get to 40-60 mins
6) How does REM differ for infants compared to adults? Spend more time in REM.

Document Summary
In stage 1, breathing and heart rate slow as muscle tension and body temp decline. In stage 1, alpha waves dominate eeg activity and right before you fall asleep, theta waves are emitted. Contribute to to firming up learning that taes place during the day. Disease marked by sudden and irresistible onsets of sleep during normal waking periods. Frequent, reflexive gasping for air that awakens a person and disrupts sleep. Sleepwalking; occurs when a person arises and wanders about while sleeping. Tryptophan is an amino acid that can help calm you down. Melatonin is a hormone produced by body at night. Make you sick leading to more head colds. Put books/ hw away 30 mins before bed. What is (cid:862)day residue? (cid:863: describe the three major theories of dreaming, wish fulfillment, problem-solving, activation-synthesis. What research supports role expectations: explain how dissociation can be used to support an altered state of hypnotic consciousness.
