Q

What is the difference between cognitive ability and cognitive performance?

A
  • Cognitive ability refers to a trait (an intrinsic state, which is stable)
  • Cognitive performance refers to a state (the outcome that you generate at a moment)

A

We need to use cognitive performance to infer cognitive ability as we cannot directly measure cognitive ability while we can measure cognitive performance.

Q

Do people need to train their low-level cognitive ability?

A

Majority of people do not need to train their low-level cognitive system

22
Q

What does reaction time test?

A

Reaction time tests your sensory ability (low-level cognitive ability)

23
Q

What is mental speed?

A

Mental speed is the entire process of processing something

24
Q

What makes a cognitive ability? (3 criteria)

A
  1. It can be reliably measured
  2. The measurement should be valid
  3. It is different from other existing abilities
25
Q

How is a measurement reliable?

A

The measurement should generate consistent results in terms of cross-person ranking across measurements.

26
Q

How is a measurement valid?

A

A measurement of cognitive ability is considered valid if it truly measures the said ability

27
Q

How can you know if the measurement is reliable?

A

The person should have similar performances in different times when doing the same task

28
Q

What are some examples that the measurement is not reliable?

A

Activities that are determined by randomness

29
Q

Does a measurement with a high reliability necessarily have high validity?

A

No, measurement with high reliability does not mean that the cognitive ability being measured is a valid one.

30
Q

How can we validate a measurement?

A

We can use existing knowledge of other ability to validate a measurement.

31
Q

What is executive function? (2 definitions)

A
  • The ability to control yourself to achieve something / drive yourself to do something
  • highlevel processing that, through their influence on lower-level processes, enable individuals to regulate their thoughts and actions during goal-directed behaviours
32
Q

What are the three dimensions of executive functions?

A
  1. Inhibition function
  2. Shifting function
  3. Updating function
33
Q

What does inhibition function do?

A

Inhibition function is used to deliberately override dominant responses to resist distractions

34
Q

What does inhibition function do?

A

Inhibition function is used to deliberately override dominant responses and to restrict distraction by inhibiting/ refraining yourself from doing something.

35
Q

What task can measure inhibition function?

A

Stroop task measures the inhibition function.
- It presents incongruent list with tow conflicting dimensions of information with each other.

36
Q

How can you test the measurement reliability of inhibition function?

A

You can measure inhibition functions for different people and for a longer time to evaluate reliability of different people by comparing scores for the first and second times

37
Q

How can you test the measurement validity of inhibition function?

A

You can generate another task that also measures the inhibition function
- can use the flanker test (about the directions of arrow movement), Simon task (pointing direction of arrow)
- use a greater variety of different types of task to test the validity

38
Q

What does shifting function do?

A

It is used to switch flexibly between tasks or mental sets.

39
Q

What does shifting function require?

A

Shifting function requires cognitive effort to switch from one task to another

40
Q

What task can measure shifting function?

A

Tasks that require switching can measure shifting function.
- e.g. asking the participants to report the ink colour of a word, after a few items, ask the participants to report the semantic colour.

41
Q

How can you test the measurement reliability of shifting function?

A

You can measure the score generated by the task and use the task to measure it again at a different time point

42
Q

How can you test the measurement validity of shifting function?

A

You can come up with different tasks for the shifting functions to test the validity.

43
Q

What does updating function do?

A
  • Updating function is used to monitor and engage in rapid addition or deletion of working memory contents
  • it needs to delete something in working memory and replace it with something else
44
Q

What can be used to test the updating function?

A

Keep track task can be used to test the updating function.
- It is shown with a sequence of stimuli one by one
- the participant has to remember the last item (previous item) under each category

45
Q

What is used to measure reasoning?

A

Raven’s progressive matrices test
- a set of reasoning problems with increasing difficulty
- uses two different dimensions of data (two behavioural data) to measure the person’s performance

46
Q

What are the two behavioural data in Raven’s progressive matrices test?

A
  1. The time for a person to finish a task
  2. The number of tasks correctly answered
47
Q

What is creativity?

A

It is defined as a product or an idea that is original and therefore new, unusual, novel or unexpected, that is deemed valuable, useful or appropriate.

48
Q

What function does creativity belong to?

A

Creativity is a cognitive function.

49
Q

Of what level is creativity of the cognitive function?

A

Creativity is a very high level of cognitive function.

50
Q

What task can measure the creativity?

A

Divergent thinking task can measure the creativity.

51
Q

How does the divergent thinking tool work?

A

The participant has to provide multiple ideas in response to specific stimuli that is rated by human raters (can be self-report or other people report)

52
Q

What does creativity assess?

A

Creativity assesses
1. Fluency (the number of ideas)
2. Originality (evaluate the quality/ novelty of ideas)
3. Flexibility (the diversity or variety of ideas)
4. Elaboration (the details of ideas)
