Q

How can an ASC occur?

A
  • Naturally, such as sleep or daydreaming

- Purposely induced, such as meditation, hypnosis, alcohol ingestion or by taking medication or drugs

17
Q

What are some signs that someone is in an ASC?

A
  • Perceptual and cognitive distortions
  • Disturbed sense of time
  • Changes in emotional awareness
  • Changes in self-control
18
Q

What effect may an ASC have on the senses?

A

Either makes someone more receptive to external stimuli or dulls to such an extent that some sensations are not experienced at all. Colours seem brighter, tastes and smells are stronger, sounds are louder and touch more sensitive.

19
Q

How can cognitive functioning be impaired in an ASC?

A

Thought processes are more disorganised, thinking may be illogical and lacking in sequence, difficulties may be experienced in problem solving. May also have trouble remembering events.

20
Q

How is time orientation effected in an ASC?

A

Time seems to pass at a different speed than normal.

21
Q

How do changes in emotional awareness occur in an ASC?

A

It may put an individual’s feelings into a state of turmoil, resulting in uncharacteristic responses. Unpredictable emotional responses are often associated with ASCs.

22
Q

How are changes in self-control associated with ASCs?

A

In an alcohol induced ASC, individuals often have difficulty coordinating and controlling movements, sometimes being unable to walk down a hallway without stumbling into the walls.

23
Q

Define Daydreaming

A

An altered state of consciousness in which we shift our attention from external stimuli to internal thought, feelings or imagined scenarios.

24
Q

What are some changes that generally occur when someone has entered and alcohol induced ASC?

A
  • Shortened attention span
  • Impaired perceptions
  • Impaired thinking
  • Impaired memory
  • Slower reaction times
  • Reduced self-awareness
  • Impaired emotional awareness and control
  • Impaired perception of time
  • Less self-control
  • Difficulties with voluntary muscular control and fine movements
  • Deterioration in performance of complex tasks
25
Q

What is an Electroencephalograph (EEG)?

A

A device that detect, amplifies and records general patterns of electrical activity of the brain.

26
Q

What form does an EEG present its results in?

A

A visual pattern of brain waves.

27
Q

What are the 4 types of brain waves?

A
  • Beta
  • Alpha
  • Theta
  • Delta
28
Q

Describe the frequency and amplitude of Beta brain waves

A

High frequency

Low amplitude

29
Q

Describe the frequency and amplitude of Alpha brain waves

A 
High frequency
Low amplitude (but slightly higher than Beta waves)
30
Q

Describe the frequency and amplitude of Theta brain waves

A

Medium frequency

A mixture of high and low amplitude waves

31
Q

Describe the frequency and amplitude of Delta brain waves

A

Low frequency

High amplitude

32
Q

What is an Electrocardiograph (ECG)?

A

A device that detects, amplifies and records the electrical activity generated by the heart. Specifically looks at how fast the heart beats.

33
Q

What are the 4 physiological responses that can be measured to see if someone is in an ASC?

A
  • Brain waves (EEG)
  • Heart rate (ECG)
  • Core body temperature
  • Galvanic skin response
34
Q

What is the Galvanic Skin Response (GSR)?

A

A physiological response that indicates the changes in resistance of the skin’s surface to the passage of an electrical current.
