Q

Why is consciousness (+any ASC) referred to as a hypothetical construct?

A

Consciousness is not directly observable or measurable but it is assumed/inferred to exist on the basis of self reports and observable activity

Q

Hypothetical construct

A

a concept used to describe something that is believed to exist because we can measure its effects but we cannot directly observe or measure it.

Q

Consciousness is individual because it is…

A

Personal- private, unique, subjective
Changing- always different, moving from topic to topic
Continuous- constant, can’t turn it off, individual is always aware of something, never empty, no beginning or end
Selective- voluntary direct attention, pay attention to some things and ignore others

Q

Differences between and ASC and NWC in terms of AASSCCEP

A

Level of awareness-
NWC- high level of awareness of internal and external environments
-able to complete controlled and automatic processes
ASC- low level of awareness of internal and external environments
-limited ability to complete controlled processes and some automatic processes are impaired

Attention-
NWC- focused attention on seleted stimuli
-able to divide attention between two tasks
ASC- low level of ability to attend to stimuli

Content limitations
NWC- able to control thoughts
-thoughts are logical and organised, and are usually limited to reality
-able to process a lot of information at one time
ASC-unable to block unacceptable or undesirable thoughts from entering consciousness
-limitations are reduced (as thoughts are not limited to reality)
-amount of information we can process is limited

Sensations and perceptions
NWC- able to accurately perceive the world
-experience sensations that are real
ASC-experience distorted perceptions of the world (delusions and hallucinations)
-reduces or heightens the experience of pain
-sense of reality is compromised
-sensations and perceptions are dulled or blunted, or sharpened

Cognitive distortions
NWC-able to think logically and clearly
-able to memorise and recall information accurately
ASC- experience illogical thoughts that are disorganised, illogical, fragmented and lacking sequence
-memory and recall is less accurate
-everyday tasks become difficult

Emotional awareness
NWC-emotions are generally appropriate to the situation in terms of experience and intensity
ASC- emotions can be blunted, intensified or totally inappropriate to the situation

Self-control
NWC- exhibit fine motor skills
-can coordinate complex movements
-can make decisions that consider the likely outcome and implications
ASC- unable to coordinate actions an behaviours
- loss on inhibitions

Time orientation
NWC-perception of time is generally accurate
ASC- perceptions of time are often distorted (may pass faster or slower)

Q

Divided attention

A

when an individual simultaneously focuses on two or more stimuli, or simultaneously undertakes two or more tasks
*two or more tasks are easier to do than two similar tasks

Q

Hallucination vs. Delusion

A

hallucination- a sensory experience (seeing or hearing something) that does not actually exist… hallucination= sensation

delusion- a belief or thought that is not supported by or connected to reality… delusion = belief

Q

Day dreaming

A

An ASC characterised by a shift in concentration from external stimuli to internal thoughts, feelings, memories and images.
more likely to daydream when stationary, doing routine or boring activities
we daydream every 90 minutes
teenagers spend 1/3 of the day daydreaming
main content= problem solving, planning

Q

Hypnosis

A

An ASC characterised by narrowed attention and increased openness to suggestion
-e.g. pain relief, phobias, entertainment, quit smoking, weightloss

17
Q

Physical and psychological alcohol and drugs

A

-physical effects= loss of self control
slower reaction times
inaccurate perceptions

-psychological effects= increased confidence
dulled or heightened emotions
reduction in the experience of pain
disorganised or unclear perceptions of the world

Q

Objective data

A

Data collected under controlled and unbiased conditions.

20
Q

Electrocardiography (ECG)
What does it measure?
How does it indicate an ASC or NWC

A

A machine used to detect, amplify and record the electrical conductivity of the heart
heart rate will increase or decrease depending on the state of consciousness

21
Q

Body Temperature
How is it recorded?
What is normal body temp?
How much does body temp drop when asleep?

A

thermometer- a device used to measure body temperature

22
Q

Electroencephalograph (EEG)
What does it measure?
What is it measured in?

A

A machine used to detect, amplify and record the electrical conductivity of the brain, measured in the form of brainwaves?

23
Q

Frequency

A

how often it happens (brainwaves per second)

24
Q

Amplitude

A

height (peaks and troughs)

25
Q

What are the four types of brainwaves?

What is their amplitude and frequency

A

B Beta- characteristic of NWC, low amplitude, high frequency
A Alpha- experienced during a deeply relaxed state, low-medium amplitude, high-medium frequency
T Theta- experienced during the early stages of sleep, medium-high amplitude, low-medium frequency
D Delta- experienced during the deepest stages of sleep, high amplitude, low frequency

Q

Galvanic Skin Response (GSR)
