Q

Describe the point scale concept.

A

A test in which points (0, 1, or 2) are assigned to each item. The advantage of the point scale, is that all items with a particular content can be grouped together. Items ordered in increasing difficulty level (0,1,2) by content.

Q
  1. Know the pros/cons of the alternative ability tests
A

Cons

  • Weaker standardization sample (not as representative as binet or wechsler)
  • Less stable
  • Less documentation on validity
  • Limitations in test manual (some do not have detailed standard administration instructions)
  • Not as psychometrically sound
  • IQ scores not interchangeable with Binet or Wechsler

Pros

  • Can be used for specific populations and special purposes (sensory limitations–physical limitations–language limitations–culturally deprived people–foreign born individuals–non English speaking people)
  • Not as reliant on verbal responses
  • Not as dependent on complex visual-motor integration
  • Useful for screening, supplement, and reevaluations
  • Can be administered nonverbally (using a performance scale)
  • Not highly correlated with scholastic achievement (this is because reading ability is not emphasized on the alternatives)

Q

What is meant by the factor analytic approach?

A

The factor analytic approach is an empirical strategy (“statistical strategy”)
-uses factor analysis to REDUCE data to a small number of traits/basic dimensions of personality
Example: If an aggression scale and a hostility scale highly correlate with each other (share common variance), they may be reduced to measuring one trait, which is paranoid personality

Q

What is meant by the factor analytic approach?

A

The factor analytic approach is an empirical strategy (“statistical strategy”)
-uses factor analysis to REDUCE data to a small number of traits/basic dimensions of personality
*Therefore, it reduces redundancy
Example: If an aggression scale and a hostility scale highly correlate with each other (share common variance), they may be reduced to measuring one trait, which is paranoid personality

Q

What is meant by the logical-content approach?

A

The logical-content approach is a deductive strategy. -Items are selected using logic and deductive reasoning
-It assumes that the test item describes the subject’s personality and behavior (Basically face validity which is no longer an acceptable form of validity)

Q

Wechsler’s performance scale was the first to offer the possibility of directly comparing an individual’s verbal and nonverbal intelligence. Why can verbal and nonverbal intelligence be compared?

A

Both the verbal and nonverbal scales were standardized on the same sample and the results of both scales were expressed in comparable units.

16
Q

What does the performance scale attempt to overcome?

A

Biases caused by language, culture, and education

17
Q

What components of performance tasks provide clinicians with an opportunity to observe behavior in a standard setting?

A

They require a longer interval of:

  1. sustained effort
  2. attention
  3. concentration
18
Q 
The Verbal Comprehension Index includes 4 sub-tests: 
 1. Vocabulary 
2. Similarities
3. Information
4. Comprehension
What does each sub-test measure?
A
  1. Vocabulary: ability to define words; only more severe emotional problems/brain damage will influence this score because it is the most stable sub-test.
  2. Similarities: ability to see the similarity between apparently dissimilar objects or things; gives information about a person’s thought process (may reveal schizophrenia)
  3. Information: range of knowledge, curiosity, and cultural interests
  4. Comprehension: Judgement in everyday situations; common sense; may reveal emotional problems
19
Q 
The Perceptual Organization Index includes 4 sub-tests:
1. Picture Completion
2. Block Design
3. Matrix Reasoning
4. Visual Puzzles
What does each sub-test measure?
A
  1. Picture completion: attention to detail and visual processing
  2. Block Design: Non-verbal reasoning and visual motor integration (it has a problem solving and abstract reasoning component as well, but that was Wechsler’s intention)
  3. Matrix Reasoning: Inductive Reasoning; also measures fluid intelligence, information processing, and abstract reasoning skills
  4. Visual Puzzles: strategy, integration, visual-spatial ability
20
Q 
The Working Memory Index includes 3 sub-tests:
1. Arithmetic
2. Digit Span
3. Letter-number Sequencing
What does each sub-test measure?
A
  1. Arithmetic: concentration and working memory
  2. Digit Span: Immediate memory and anxiety (Note: repeating digits backwards requires working memory because you have to think about it rather than repeating exactly what you just heard.)
    Letter-number Sequencing: working memory and attention; individual is given a mix of numbers and letters–>they must first list the numbers in order and then list the letters in alphabetical order
21
Q

The Processing Speed Index includes 2 sub-tests:
1. Digit Symbol Coding
2. Symbol Search
What does each sub-test measure?

A
  1. Digit Symbol Coding: Visual Motor Functioning

2. Symbol Search: Visual Information Processing Speed

22
Q

The Woodcock-Johnson III Tests of cognitive Abilities and Achievement Skills is one of the better tests used to detect learning disability. What 5 things does it evaluate?

A
  1. psychometric “G” (full scale IQ score)
  2. specific cognitive abilities
  3. scholastic aptitude
  4. oral language
  5. achievement
23
Q

How is the Bender Visual Motor Gestalt Test scored, and what do poor scores indicate?

A
  • It is scored according to the number of errors the participant makes
    • Significant errors occur for people whose mental age is less than 9, have organic brain damage, have nonverbal learning disabilities, and/or have emotional problems
24
Q

When using the Woodcock-Johnson III Tests of Cognitive Abilities and Achievement Skills, cognitive scores can be compared with each other, achievement scores can be shared with each other, and cognitive scores can be compared with achievement scores. Why is this possible?

A

The Cognitive Tests and the Achievement Tests were normed together.

25
Q

When referring to the Woodcock Johnson III, a major discrepancy between cognitive ability and achievement would be indicated by how many standard deviations?

A

1.5 to 2 SDs

26
Q

How many sub-tests does the Cognitive Ability Standard Battery include? How many more are included in the extended batter?

A

Standard Battery: 10 sub-tests

Extended: another 10 sub-tests

27
Q

How many subtests does the Standard Achievement Battery include? How many sub-tests are included in the Extended version?

A

Standard Battery: 12 sub-tests

Extended: another 10 sub-tests

28
Q

What are the mean and standard deviation of the Woodcock-Johnson III ‘s standard score?

A

Mean=100, SD=15

29
Q

What are the psychometric properties of the Woodcock-Johnson III test?

A
  • solid representative sample (8818 pple)
  • solid construct validity
  • split-half (internal consistency) reliabilities from .80’s to .90’s
30
Q

What is the Wide Range Achievement Test-4 (WRAT-4) used to measure?

A

It assesses grade level functioning in word reading, spelling, math computation, and sentence comprehension.

31
Q

Is the WRAT-4 a popular test? Why?

A

Yes. It is easy to administer.

32
Q

What should the WRAT-4 mainly be used as? What should it not be used as?

A

The WRAT-4 should be used as a “screener”. It does not replace the Woodcock-Johnson and should not be used as an achievement test.

33
Q

Is the WRAT-4 Psychometrically sound?

A

That is under debate.
-It provides reliability and validity information, but this was based on small sample sizes, making it hard to document convergent and discriminant validity.

34
Q

On what principle are visiographic tests based? (Benton Visual, Bender Visual Motor, and Memory for Designs)

A

The three visiographic tests are based on the principle that brain damage impairs visual memory

35
Q

What makes personality states different from personality traits or types?

A

Personality states vary based on the situation a person is in; “situationally bound”

36
Q

MMPI

A

everything about it.

37
Q

The Factor Analytic Strategy is based on the Empirical Approach. What are the three assumptions that guide development of this type of personality test?

A
  1. personality characteristics/traits are stable
  2. personality characteristics/traits are different for different individuals
  3. personality traits can be measured
38
Q

The MMPI and MMPI-2 use which type of empirical strategy?

A

Criterion-Group Strategy

39
Q

What testing format is used for the MMPI and MMPI-2?
