Q

What is consciousness?

A

The awareness of our own thoughts, feelings and perceptions (internal events) and our surroundings (external stimuli) at any given moment. It creates our reality and is central to our sense of self.

Q

What are the 5 characteristics of consciousness according to William James?

A
  • is continuous: it’s never empty, thoughts aren’t isolated and can flow easily from one topic to another with interruption.
  • is ever changing: it rarely travels along one line of thought and constantly changes as we become aware of new info.
  • is a highly personal experience: it relies on our own thoughts, feelings and perceptions.
  • is selective: we can usually choose to focus on some things and ignore others; we can focus on internal events (thoughts, feelings and perceptions) and/or external surroundings.
  • is active: consciousness has a purpose to allow us to function in our world.

Q

What is normal waking consciousness?

A

The states of consciousness you can experience when you are awake and aware of your thoughts, feelings and perceptions from internal events and the surrounding environment. During NWC you experience a real sense of time and place. Your experience during NWC creates your reality and provides a baseline from which to judge all other states of consciousness.

Q

What are levels of awareness?

A

A number of levels of awareness exist during NWC. It’s not unusual to swap ‘consciousness’ with the term ‘awareness’ since they’re linked together. Various levels of awareness can be viewed as a continuum of awareness. NWC occupies the middle part of the continuum, whereas ASC occupy the sections below and beneath NWC.

Q

What are content limitations?

A

Due to thoughts being more logical and organised during NWC and attention being more focused, the content (type of info) of NWC is more restricted than the content of ASC. Our thoughts tend to not be as cognitive, bizarre, unrealistic or impossible compared to our thoughts during an ASC.

Q

Give examples for stimuli that attract our attention.

A
  • novel stimuli (such as something new or unusual)
  • changes in stimulation (such as the volume on a radio suddenly increasing)
  • something that’s personally meaningful to us (such as our name being mentioned across a crowded room) or important to us to attend to at the time.

Q

Define selective attention and provide example.

A

Focusing on one task and ignoring others. It’s usually difficult to attend to more than one event at the same time, therefore you may not notice (consciously attend to) other events at the same time. Content limitations during NWC are normally due to this. E.g. Driving a car

Q

Define selective inattention and provide example.

A

Diverting attention away from our consciousness can be helpful or unhelpful. Avoids attending to info that may be relevant but emotionally upsetting, e.g. Trying not to think about how nervous you are about a SAC.

16
Q

Define divided attention and provide example.

A

At the top of the consciousness continuum (higher level of awareness) a higher level of attention is required and this tends to be selective. As you move down the continuum, you become less aware and attention tends to be divided. It refers to the capacity to attend to and perform two or more activities at the same time. This is generally only possible if the tasks are performed with very little mental effort e.g. we can talk as we walk or type as we read.

17
Q

What limits does divided attention have?

A

It’s harder to perform 2 or more tasks simultaneously when they require similar mental skills and more than one is a complex (controlled) process. In summary, performance on tasks that require divided attention is usually poorer when:

  • the tasks are similar
  • are not well practiced
  • are difficult and complex
18
Q

If tasks are similar, how is performance affected by divided attention?

A

You would need to shift attention back and forth between both tasks and it would be too difficult to do. Effort and attention would lower due to too much difficulty trying to pay attention to both.

19
Q

If tasks are difficult or complex, are we better off using selective or divided attention?

A

Selective attention because all focus can be put towards one task.

20
Q

What is the cocktail party phenomenon? What does it suggest about attention and consciousness?

A

Refers to actively processing info outside of our conscious awareness. It shows that much more info is processed in our consciousness than that to which we initially attend. Therefore, consciousness may not be limited to what you are attending to at the time.

21
Q

What are automatic processes?

A

Automatic processes are tasks that require very little awareness or mental effort to be performed well and they generally don’t interfere with other automatic or controlled processes. They become procedural memories. E.g. Texting on a mobile phone for someone that has learnt to do it with ease.

22
Q

What are controlled processes?

A

Tasks that are complex and require full attention. They require more awareness and mental effort to focus attention on the required task. This means being unable to complete another controlled process at the same time as they both require full attention and therefore will interfere with each other. Learning how to drive for example is initially a controlled process that develops into an automatic process.

23
Q

Tasks that require selective attention require which process?

A

Controlled, driving for example is always considered a controlled process because conditions are unpredictable and selective attention is needed.

24
Q

Tasks which require divided attention require which process?

A

Automatic.

25
Q

Define the term perception.

A

Process of organising sensory input and giving it meaning. During NWC, our perceptions are usually clear and rational. We can make sense of sensory input and have a real awareness of our internal state and any external stimuli.

26
Q

Define the term cognition.

A

Broad term that relates to mental activities such as thinking, problem solving, language and reasoning. During NWC, we have a sense of reality. Our thoughts are usually rational, clear and meaningful. We are capable of cognition - problem solving, analysis and reasoning.

27
Q

List 2 characteristics of emotional awareness.

A
  • active during NWC: aware of our feelings and show a range of emotions that’s normal for us and appropriate for the situation.
  • can usually monitor emotions and hide our true feelings from others.
28
Q

List 2 characteristics of self control

A
  • maintained during NWC.

- entails planning and monitoring what we say and do.

29
Q

Define the term time orientation.

A

During NWC, we usually have a good awareness of the passage of time. Time is perceived as moving at the ‘real time’. It’s knowing and understanding the passing of time.

30
Q

What are the signs of someone not being in a normal state of consciousness?

A
  • non-responsive
  • abnormal behaviour e.g. Aggressive, change in self control and risk taking decisions
  • hyperactive
  • sleepy
  • confusion
  • physical changes e.g. Slower reflexes, walking clumsy, slurred speech.
31
Q

What is daydreaming?

A

Shifting attention to private thoughts, feelings and imagined scenarios. It’s considered an altered state of consciousness and tends to be visualised thoughts that are usually positive and/or pleasurable.

32
Q

List some ways that daydreaming is different from NWC.

A
  • level of awareness: external awareness is decreased and internal awareness is increased.
  • ability to carry out controlled processes: more difficult to perform and ability to perform 2 or more tasks is lowered.
  • time orientation: is diminished and time can appear to move faster or slower.
33
Q

Why is alcohol classed as a depressant?

A

Because it slows down nervous system activity; it depresses it.

34
Q

List some ways that an alcohol-induced state is different to NWC?

A
  • self control: can decrease self control in terms of regulating emotions and balance in the body e.g. While in an alcohol-induced state you are likely to be less able to walk in a straight line.
  • content limitations: less restricted in terms of thoughts. Thoughts can be unrelated, obscure and/or irrational. This can be due to ability to concentrate on certain tasks being impaired. Information that enters consciousness may be broader.
  • perceptual and cognitive distortions: thoughts can be distorted or nonsensical as well as perceptions and behaviours e.g. Reaction time and reflexes are slowed.
  • emotional awareness: changes in emotions e.g. False sense of confidence or showing inappropriate emotion for a situation.
35
Q

Explain the difference between selective attention and divided attention.

A

Selective attention refers to focusing attention to one task or stimulus, whereas divided attention refers to splitting attention between 2 or more tasks. These tasks generally require little mental effort, however if 2 tasks are similar or difficult and complex then performance will be poorer.
