21
Q

What is the Psychological Indicator ‘Content Limitations’

A

the type of information held in consciousness sand our control of the information

22
Q

What are the Perceptrual and Cognitive characteristics in each NWC (3) and ASC (3) ?

A

NWC

  1. perceptions (eg.pain) realistic.
  2. Effective control of memory storage and retrieval.
  3. Thoughts are organised and logical

ASC

  1. perceptions may be altered
  2. memory storage and recall may be fragmented or less accurate
  3. thoughts disorganized and less logical
23
Q

What are the PHYSIOLOGICAL indicators of Consiousness

A
  • brain wave pattern
  • body muscle activity
  • eye movements
24
Q

What are Brain Waves measured by?

A

EEG

25
Q

What is the defintion of EEG?

A

An EEG detects, amplifies and records electrical activity of the brain in the form of brain waves

26
Q

Briefly outline what Brain waves are described through (2)

A

AMPLITUDE - size of peaks

FREQ - number of brainwaves per sec

27
Q

Name the four types of Brain Waves (in order)

A
  1. Beta
  2. Alpha
  3. Theta
  4. Delta
28
Q

THETA

32
Q

Which brain wave patterns show a mix of both high AND low amplitude?

A

Theta + Delta

33
Q

Which brain wave occurs when one is in a deep DREAMLESS sleep, or unconscious?

A

DELTA

34
Q

Muscle Activity is measured through an EMG. What does EMG do?

A

it dectects, amplifies and records the electrical activity of muscles

35
Q

Throgh the EMG, we can conclude that the higher ____________, the higher the ___________

A

muscle activity, alertness

36
Q

What is the defintion of EOG?

A

detects, amplifies and records the electrical activity of muscles that control eye movements

37
Q

What does the EOG indicate

A

the strength of electrical activity in the muscles surrounding the eyes

38
Q

What do Psychoactive Drugs do to the brain neurotransmitters?

A

they modify actions of brain neurotransmitters by increasing or decreasing activity

39
Q

What 2 aspects do Psychoactive Drugs alter?

A
  1. thoughts/feelings/perspectives

2/ brain wave activity

40
Q

Name the two types of Psychoactive Drugs

A

stimulants + depressants

41
Q

What do Stimulant Drugs do (2)

A
  1. increase NS activity ( increase ANS activity (eg heart rate))
  2. increase alertness
42
Q

What do Depressant Drugs do (2)

A
  1. decrease NS activity ( decrease ANS activity )

2. decrease alaertness

43
Q

What freq are brain waves after STIMULANTS are taken? List the three waves involved

A

High freq. –> Gamma, Beta, Alpha

44
Q

What freq are brain waves after DEPRESSANTS are taken? List the three waves involved

45
Q

Give two examples each for Stimulant and Depressant drugs.

A

Stimulants –> caffeine + cocaine

Dep –> alcohol + barbiturates
