       Drugs
        Unit 6
True or False?   1. People prone to delinquency and
                    violence have fewer vivid fantasies.

                 2. People who sleep eight hours a night
                    tend to outlive those chronically sleep-
                    deprived.

                 3. The most common dreams are those with
                    sexual imagery.

                 4. Under hypnosis, people can be induced
                    to perform feats they would otherwise
                    find impossible.

                 5. In large amounts, alcohol is a
                    depressant; in small amounts, it is a
                    stimulant.
Waking and Sleeping
        m18
Waking Consciousness
Consciousness: our
awareness of ourselves
and our environments.

   Conscious processing
   is serial.

   Subconscious
   processing is parallel.

   Reminder: Optimal
   arousal.
Daydreams are perfectly normal for most people.

   Daydreams can be escapist or rehearsal;
   daydreaming is adaptive.

    Can substitute for impulsive behavior.

   95% of people have sexual fantasies everyday.

   4% of the population suffers from fantasy-prone
   personality disorder.

    75% report spontaneous orgasm.
Biological rhythms:

     Annual cycles

     Twenty-eight day cycles

     Twenty-four hour cycles

     Ninety-minute cycles

Circadian rhythm

     Biological clock; 24-hour
     cycle

     Can be affected by light -
     light behind knees; artificial
     light delays sleep.
Stage 1

     Alpha waves

     Hallucinations

     Hypnogogic
     sensations

     Heartbeat &
     respiration slows
Stage 2
                           Stage 4
     Alpha waves, but        – Delta waves
     sleep spindles.         – Bed wetting & sleep-
     Possible sleep talk       walking.

     About half the
     night is spent in
     Stage 2

Stage 3

     Delta waves

     Transitional stage
     only
REM sleep

     Alpha waves

     Nocturnal erections

     “Paradoxical sleep”

       Busy mind; still body

       Medulla inhibits movement
       messages

     REM dreams are more emotional &
     storylike
0 = would never doze
        1 = slight chance of dozing
        2 = moderate chance of dozing
        3 = high chance of dozing



A. Sitting and reading

B. Watching TV

C. Sitting, inactive in a public place, e.g., a theater or
   meeting

D. As a passenger in a car for an hour without a break

E. Lying down to rest in the afternoon when
   circumstances permit

F. Sitting and talking to someone

G. Sitting quietly after a lunch without alcohol

H. In a car while stopped for a few minutes in traffic
