1
New cards

constructs

concepts that require a belief in something that cannot be seen or touch, but seem to exist because of their effect on behavior

2
New cards

consciousness

the subjective awareness (or perceptions) of the environment and of one's own mental processes [External & Internal components]

3
New cards

What do some psychologists (such as Behaviorists [i.e. Watson]) believe that the science of Psychology should not deal with?

the question of the consciousness at all

4
New cards

Consciousness and Sensory Awareness

experiencing your enviroment though perception of sensory stimulation (in watered down terms: awareness of the world around us)

5
New cards

How can we adapt to our environment?

by learning what stimuli must be attended to and which can be ignored

6
New cards

Sensory as Direct Inner Awareness

knowledge of one's own thoughts, feelings, and memories without using sensory organs such as touch or smell; the subjective self

7
New cards

Consciousness as an Altered State

states other than normal waking awarness, including daydreaming, sleep, meditations, the distorted perceptions produced by drugs, or [debated] hypnosis

8
New cards

Preconsciousness

material that is not in awareness but can be brought into awareness by focusing one's attention; easy to retrieve/bring to mind

9
New cards

Subconscious

  • unavailable to awareness under most circumstances

    • Freud called this 'unconscious'

10
New cards

Nonconscious

incapable of being experienced either through sensory awareness or direct inner awareness

11
New cards

Hypnosis

an altered state of consciousness during which people respond to suggestions and behave as though they are in a trance

12
New cards

Things to remember about hypnosis

  • Not everyone can be hypnotized

  • Today, it is used in areas from entertainment to surgery to cessation therapy

    • Not valid for use in courtroom testimony, and sketchy as treatment for psychological disorders

13
New cards

How does sleep alter our consciousness?

by reducing alertness, awareness, and perception of events around us

14
New cards

sleep

 a periodic, natural reduction of consciousness

15
New cards

What is much of how people, animals, and even plants function governed by?

circadian rhythms (Latin for 'around the day') (aka "biological clocks")

16
New cards

What is the circadian rhythm of humans?

a cycle of changes (such as temperature or wakefulness) which occur about every 24 hours

17
New cards

What did sleep researchers discover by brain wave patterns measured by EEG?

we sleep in stages

18
New cards

Pre-sleep/sleep onset stage

When we close our eyes to relax before falling asleep, our brain slows

19
New cards

Stage 1 [NREM-1]

  • Lightest stage of sleep from which you can be easily awakened

  • May be accompanied by a dreamlike state where we experience brief hallucinatory, dreamlike images

20
New cards

hypnagogic sensations

This is when you may also experience that sensation of falling (at which moment, your body may suddenly jerk!) or floating weightlessly

21
New cards

After how many minutes of stage 1 do we descend into stages 2 and 3?

After about 30 minutes

22
New cards

Stage 2 [NREM-2]

  • Has medium brain waves with short bursts of activity about every 15 seconds

  • If/when awakened from this deep sleep, a person is groggy and confused (almost inebriated-like experience)

23
New cards

sleep spindles

short bursts of neural activity. May possibly be tied to memory consolation

24
New cards

How long does it take to go through the sleep stages?

It takes about an hour to go through the stages, then the cycle reverses itself (back to 2 & 1, then REM)

25
New cards

REM sleep

characterized by rapid eye activity under closed eyelids; brain waves resemble the walking state [aka paradoxical sleep]; the body also typically experiences temporary paralysis

26
New cards

How many trips through the sleep stages do you experience with 8 hours of sleep?

5 trips

27
New cards

As the night goes on which stages get shorter and which grow longer?

As the night goes on, Stage 3 sleep gets shorter and REM grows longer

28
New cards

Three Sleep Functions

  1. Protection

  2. Helps us recuperate

  3. Sleep helps store/restore memories ()

29
New cards

During sleep where are recent experiences stored? Where are they shifted to?

stored in the hippocampus are shifted to permanent storage in the cortex

30
New cards

What does deprivation of REM sleep cause?

difficulty learning or retrieving memories

31
New cards

REM rebound

following REM deprivation, the tendency for REM sleep to increase

32
New cards

Effects of sleep deprivation

experiments show problems in attention, confusion, and misperception

33
New cards

Dreams

images or thoughts that occur mainly during REM sleep

34
New cards

What do dreams primarily reflect?

biological activity - brain is interpreting signals from the body

35
New cards

Why do we tend to dream about the events of the day?

most current neural activity of the cortex would be that which represented the events or concerns of the day

36
New cards

Nightmares

distressing dreams that tend to occur during, and awaken a person from, REM sleep

37
New cards

Night Terrors

horrific dreams that tend to occur during deep sleep; stage 3

38
New cards

Insomnia

  • the inability to fall asleep and/or stay asleep

    • Sleep onset - difficulty falling asleep

    • Difficulty remaining asleep through the night

39
New cards

How many Americans are affected with insomnia?

about 1/3

40
New cards

Effects of insomnia

Shown to have more anxiety; have more muscle tension; are more depressed

41
New cards

Sleep Paralysis

terrifying experience in which the body becomes paralyzed during REM sleep, and remains so, even after one wakes.

42
New cards

REM Sleep Behavior Disorder

condition in which person physically and/or vocally acts out dreams during REM sleep; typically wake up easily and remember dream

43
New cards

Narcolepsy

sufferers fall asleep suddenly into REM sleep (usually less then 5 min), at unpredictable and/or inappropriate times

  • Medications (amphetamines) have helped some sufferers, but there is no known cure

44
New cards

Apnea

sleepers stop breathing (from seconds to minutes) repeatedly through the night

  • Can be treated with a CPAP nasal mask or surgery

45
New cards

Sleepwalking (Somnambulism)

excursions the person does not remember because they take place in very deep stages of sleep (not REM); tends to run in families
