Q

How can intelligence testing help with measuring change over time?

A

Test results can act as a baseline to assess change over time.

Can identify progress, and decline in functioning and also measure the efficacy of interventions.

Q

In terms of test delivery, what are some of the benefits of intelligence tests compared with other tests?

A

Able to be delivered consistently as they are less reliant on clinical interpretation or variability or assessors

Q

Why can predicting academic success just using IQ scores lead to a high chance of failure?

A

Because all of the variables which are related to success cannot and are not measured by a test

Q

What is one misinterpretation of IQ scores

A

That they measure innate, fixed capacity.

This is not true.

Q

Should IQ scores be used to predict long-term performance?

A

No.

They should only be used to predict short-term performance, instead of long-term as there are too many influencing variables.

However, they are often used to predict long term performance.

Q

What is a key limitation in terms of the use of IQ tests and scores?

21
Q

IQ tests tend to focus on the what, instead of the how. How is this a limitation?

A

Focusing on the end product or result can often mean missing out on the nuances of a person’s overall cognitive capacity.

Q

What is a limitation of intelligence tests in an educational setting?

A

Children may be placed in boxes based on ‘strengths and weaknesses’ which are inferred by test results.

Meaning they may be unnecessarily limited in their choices based on test results which lack nuance.

23
Q

How are intelligence tests culturally biased?

A

Tend to favour WEIRD populations

24
Q

How are minorities disadvantages in terms of intelligence tests?

A

Lack of practice, issues with establishing rapport, lack of familiarity with culturally loaded items

25
Q

What has research suggested in terms of bias of IQ scores

A

That the IQ scores may not be as biased as some argue

26
Q

What sorts of tests have been created to deal with cultural bias?

A

A range of tests which are non-verbal including:

Weschler Non-Verbal Scale of Ability
Test of Nonverbal Intelligence (TONI-4)
Queensland Test (Q Test)

27
Q

What do the alternative tests suggest in terms of the fairness of the WAIS from a cultural perspective?

A

The alternative intelligence tests correlate strongly with exposure to Eurocentric educational systems.

So, the WAIS is not culturally fair.

28
Q

Why is ecological validity important in terms of the WAIS?

A

Because it confirms whether test scores can predict behaviour in the real world.

The WAIS lack ecological validity which is an issue as referrals are becoming more related to a client’s everyday functioning.

29
Q

No studies have been conducted to determine if high or low Digit Span scores relate to actual day to day behaviours.

Why is this a problem?

A

Because it there is no evidence to support the assumption that certain tests scores (e.g. Digit Span) can reflect day to day functioning.

For example, recalling phone number, following directions, etc.

30
Q

Critics of WAIS believe there is an overinterpretation of subtest and index scores.

What does this mean?

A

The reliability of the subtest scores is low.

Subtests are not specific enough.

So one should not assume these tests can indicate individual performance.

31
Q

What do some critics argue in terms of interpreting WAIS scores?

A

Assessors should only interpret the FSIQ score and not the index scores.

However, others have argued that intelligence is complex and hypothesis testing, along with the interpretation of the results against external criteria is preferable.

32
Q

What is one issue in terms of how tests are scored for the WAIS?

A

It is complex, which can lead to errors.

33
Q

Which communities may not benefit from the use of norms in terms of WAIS scoring?

A

Ethnic minorities and those from low SES communities

34
Q

What are some of the issues around using supplementary tests with WAIS

A

Lack of evidence around how the supplementary tests impact the FSIQ and index scores.

So assessors should be cautious when using the tests. Only use in special circumstances.

35
Q

Which tests have vague scoring criteria?

A

Similarities, Comprehension and Vocabulary subtests

36
Q

What aspects do the Weschler scales not measure?

A

Need for achievement
Motivation
Creativity
Social interactions

37
Q

The Weschler scales have not been updated to reflect current views on intelligence.

True or False?

A

True.

The scales have remained largely unchanged for over 50 years.

38
Q

When were the Weschler scales initially created?

A

1930s

39
Q

What were some of the issues of the Weschler-Bellevue Intelligence Scale?

A

Poor subtest reliability

Small size and lack of representativeness of normative sample

40
Q

What is the WAIS test, in terms of structure

A

Composite of intelligence tests

Battery format = multiple tests to measure intelligence

41
Q

Why is the WAIS one of the most frequently used tests in clinical practice?

A

It is psychometrically sound

Functionally and culturally relevant.

42
Q

Why is the FSIQ important in terms of test scores on the WAIS?

A

It provides the basis and context for evaluating other cognitive abilities.

Generally, the most reliable and valid score provides person’s relative standing in comparison with age-related peers.

43
Q

What age is the WAIS-IV appropriate for?

A

16 - 90 years

44
Q

What age is the WISC-V appropriate for?

A

6 - 16 years

45
Q

What age is the WPPSI appropriate for?

A

2.5 - 7.5 years

46
Q

How is split-half reliability measured?

A

Calculated by measuring performance on half of the items on FSIQ or VCI items to performance on the other half

47
Q

What does split-half reliability reflect?

A

Internal consistency of items which contribute to construct score

48
Q

What are the ranges from Test-Retest reliability results for WAIS-V?

A

0.7 (7 subscales) to 0.9 (2 subscales)

49
Q

What are the ranges for the split-half reliability for WAIS-IV?

A

Range from extremely high (FSIQ) to acceptable (Cancellation subtest).

50
Q

What are the VCI subtests?

A

Similarities
Vocabulary
Information

Supp:

Comprehension

51
Q

What are the WMI subtests?

A

Arithmetic
Digital Span

Supp: Letter-number sequencing

52
Q

What are the PRI subtests?

A

Block Design
Visual Puzzles
Matrix Reasoning

Supp:

Picture Completion
Figure Weights

53
Q

What are the PSI subtests?

A

Coding
Symbol Search

Supp: Cancellation
