Q

What is attention?

A

Attention is a concentration of mental activity that involves focusing on a specific stimulus while ignoring other stimuli. In normal waking consciousness, our attention can be focused either on internal thoughts or feelings or on external stimuli.

Q

What is the “cocktail party phenomenon”

A

If a stimulus is personally important to us, we are more likely to take notice of it.
-The greatest example of selective attention.
For example
Being total immersed in a conversation, but your attention is drawn away as you can hear someone using your name.

Q

Stroop’s experiment

A

In gobbled reading words of colours in black in the first condition, in the second the word was a colour and it was coloured another colour(The word red, that is coloured purple). Condition three was staying colours of blocks, and four was regular words that are coloured and stating the colour of the ink.

15
Q

What are the parameters of distortions of perception and cognition

A

One of two impacts it either makes them more receptive to external stimuli or dulls them to such an extent that some sensations are not experienced at all.

16
Q

What are the parameters of time orientation?

A

Time seems to pass at a different speed than normal. For some individuals in some ASCs, the passing of time may appear to be quicker, while in other ASCs, time appears to pass very slowly.

17
Q

What are the changes in emotion awareness

A

The changes in awareness can either be heightened or lowered based on the different types of emotional awareness.

18
Q

What are our changes in self control

A

Self control is lowered or heightened in these states, based around physical or behavioural occurrences.

19
Q

What is daydreaming

A

It is a form of ASC where the subject is in a trace like state making them less aware of their surroundings. This is often used to plan for future events, go in to fantasies that can not be experienced in real life, or to relive current or past experiences.

20
Q

Who is daydreaming linked to ASC

A

It is a state where the subject is cut off from the external stimuli, this is a shift in different components of the states of consciousness.

21
Q

What are psychoactive drugs?

A

Psychoactive drugs are chemicals that change conscious awareness, perception or moods.

22
Q

Name a few psychoactive drugs

A

Alcohol, coffee, tea, chocolate, cola, and nicotine.

23
Q

What is a depressant?

A

A substance that effects the senses by dulling them, making their reaction to stimuli decreased.

24
Q

What is a stimulant?

A

A substance that increases the senses abilities, this can make the senses aware of the most discreet stimulus.

25
Q

What is a alcohol induced state

A

It refers to drinks such as beer, wine or spirits containing ethyl alcohol having a substantial effect on our behaviour due the depressant effects that alcohol has.

26
Q

The effects of alcohol

A
  • a shortened attention span: for example, difficulties in maintaining concentration
  • impaired perceptions: for example, a slow-down in the processing of information from the senses, affecting sight, hearing, feeling and so on; increase in pain threshold impaired thinking: for example, difficulties with understanding, thinking clearly, applying good judgment
  • impaired memory: for example, difficulties forming new memories or memory loss (including of recent events)
  • slower reaction times: for example, not reacting to stimuli or situations quickly
  • reduced self-awareness: for example, focusing attention on the immediate situation and away from any future consequences to self
  • impaired emotional awareness and control: for example, exaggerated states of emotional experiences and responses such as anger, aggressiveness, withdrawal
  • impaired perception of time: for example, estimating time, being aware of the amount of time that has passed, knowing the time
  • less self-control: for example, being more self- confident or daring or more impulsive; saying the first thought that comes to mind rather than an appropriate comment for the given situation; acting silly
  • difficulties with voluntary muscular control and fine movements: for example, writing or signing name; experiencing uncoordinated, jerky body movements and loss of balance, stumbling and falling
  • deterioration in performance of complex tasks.
27
Q

Methods of studying alertness

A

EEG, Heart rate(ECG/EKG: Electrocardiograph), Body temperature, and Galvanic skin response.

28
Q

EEG, Electroencephalograph

A

A device that Detects, Amplifies, and Records Electrical activity of the brain

29
Q

ECG (heart rate) electrocardiograph

A

Detect, amplifies and records electrical activity of the heart

30
Q

Body temperature testing

A

Involves monitoring internal core temperature over a 24 hour period.
- It is less variable than heart rate during normal waking consciousness, despite changes in level of awareness that occur over the course of a typical day.

31
Q

GSR galvanic skin response

A

Change in the resistance of the skins surface to and electrical current

35
Q

Stream of consciousness

A

The never ending flow of thoughts, feelings, and sensations which occur often

36
Q

38

Low (but larger than beta) Ampltude

39
Q

What is the frequency and amplitude of theta waves

A

Medium frequency

High and low amplitude

40
Q

What is the frequency and amplitude of delta waves

Lowest frequency

Highest amplitude
