Q

What is the one thing that all psychological tests are considered to have in common?

A

They are tools that psychologists use to collect data about people. More specifically they are objective procedures for sampling and quantifying human behaviour in order to make inferences using standardised stimuli

Q

What are some limitations of psychological tests?

A
  1. They are only tools - they cannot make decisions for test users
  2. They are often used in an attempt to capture the effects of a hypothetical construct
  3. Tests can become obsolete due to the continual development and refinement of theories, technology and the passage of time
  4. Can sometimes disadvantage a subgroup or culture due to their experience or language background

Q

What is the difference between psychological testing and psychological assessment?

A

When we talk of psychological testing we are referring to the process of administering a psychological test and obtaining and interpreting the test scores. Psychological assessment is broader and takes into account other forms of information as well as test results

An estimate of reliability that is based on the average inter correlation of the items in a test

42
Q

Define test-retest reliability

A

A long-standing approach used by researchers seeking to evaluate reliability because it’s meaning is intuitively obvious.
It is the estimate of reliability obtained by correlating scores on the test obtained on two or more occasions. Traits considered stable should correlate highly

43
Q

Define generalisability theory

A

A set of ideas and procedures that follow from the test construction specifying the desired range of conditions over which the consistency of precision of a test is to hold.

Q

Define construct validity

A

Construct validity sees the test as an operation for giving a construct meaning and asks how well it does that

50
Q

Define content validity

A

The meaning that can be attached to a score on a psychological test on the basis of inspection of the material that constitutes the test

51
Q

How is predictive validity evaluated?

A

It is evaluated in terms of the extent to which scores on the test allow us to estimate scores on a criterion external to the test itself

52
Q

Define concurrent validity

A

A form of predictive validity in which the index of social behaviour is obtained close in time to score on the psychological test
I.e prediction when the time interval is minimal

53
Q

What is the standard error of estimate

A

It can be thought of as the standard deviation of the distribution of the differences between actual and predicted scores

54
Q

Define valid positive decisions

A

Those decisions where the person is predicated to show the characteristic of interest and this is in fact the case

55
Q

Define valid negatives

A

Are those in which the prediction is they the person does not show the characteristic of interest and this is the case

56
Q

What are false positives

A

Those decisions in which the prediction is that the person has the characteristic but in fact does not

57
Q

Define false negative

A

Are those decisions in which the prediction is that the person does not have the characteristic of interest

58
Q

Define convergent and discriminate validity

A

The subjection of a multi trait-multimethod matrix to a set of criteria that specify which correlations should be large and which small in terms of a psychological theory of the constructs

59
Q

Define a factor

A

A linear combination of the elements of a data matrix

60
Q

Cronbach and Meehl argued that tests can be invalidated

A

By correlating too highly with tests of constructs they are not supposed to be measuring

61
Q

A psychological test can be thought of as

A

A sample of items relevant to the construct of interest

62
Q

Generalisability theory

A

Is a broader theory of reliability than domain sampling theory

63
Q

Psychological tests are

A

Important tools for psychological research

64
Q

Content validity is usually restricted to

A

Achievement tests

65
Q

The Army Alpha and Beta tests were developed under the leadership of

A

Robert Yerkes

66
Q

The standard score is the basis of which derived score used in psychological testing?

A

The stand score, the standardised score and the t score

67
Q

The standard error of estimate can b determined from the knowledge of the

A

Correlation between test and criterion and the standard deviation of the criterion

68
Q

interpreting and integrating interview data into the psychological report inevitably involves what?

A

clinical judgment

69
Q

In the 1960’s C. Rogers emphasised understanding the proper interpersonal ingredients necessary for optimal therapeutic relationship. Which of the following is NOT one of these?

A

warmth
genuineness
positive regard
directiveness

70
Q

A written psychological report is preferred over a verbal report because

A

it provides and enduring record

How many composite scores can be derived from the core subtests of the WAIS-IV?

A

five

72
Q

What are the areas usually covered in a mental status examination?

A

appearance, orientation, affect, thought content and process, and insight

73
Q

What is a psychological test?

A

An objective procedure for sampling and quantifying human behaviour to make an inference about a particular psychological construct using standardised stimuli

74
Q

Why do we need psychological tests?

A

Human judgment is subjective and fallible. There are many factors that can effect human judgment such as stereotyping, personal bias, positive and negative halo effect, errors of central tendency.

Psychologists consider psychological tests better than personal judgment in informing decision making in many situations because of the nature and defining characteristics of these tests

75
Q

What is the difference between psychological testing and assessment?

A

Testing - the process of administering a psychological test and obtaining and interpreting the test scores

Assessment - a broad process of answering referral questions to which includes but is not limited to psychological testing

76
Q

What is a construct?

A

A hypothetical entity with theoretical links to other hypothesised variables, that is postulated to bring about the consistent set of observable behaviours, thoughts or feelings that is the target of a psychological test

77
Q

What is reliability?

A

Reliability is the consistency with which a test measures what it purports to measure in any given set of circumstances

78
Q

What are some of the different types of reliability?

A 
inter-rater
test retest
split half
Cronbach's alpha
parallel form
79
Q

What factors can affect the reliability of test results?

A

The person is in the bottom 2%

87
Q

In the context of psychological testing, what does standardisation mean?

A

The process of administering a test to a representative sample of test takers for the purpose of establishing norms.

88
Q

What are norms?

A

Tables of the distribution of scores on a test for specified groups in a population that allow interpretation of any individual’s score on the test by comparison to the scores for a relevant group

socio economic status
culture
ethnicity
