1
Q

What is a psychological test

A

psychological test is a set of tests that measure some aspect of human behaviour

2
Q

Name five types of psychological tests

A

IQ, personality, new scales, attitude scales, aptitude scales

3
Q

When assessing the validity what are the 4 main considerations?

A

Social desirability bias, interviewer bias, leading questions, and content validity

4
Q

What is social desirability bias

A

The participant may behave in the most socially acceptable way for the purposes of the research study

5
Q

Is social desirability bias a participant effect or not?

A

Yes it is

6
Q

What effect can and interviewer bias have and how

A

The interviewers Behaviour may affect or bias the answers. e.g. they may subtly and unconsciously tilt his head for example to encourage the correct answer to a test item when doing a face-to-face interview

7
Q

What is the problem with leading questions?

A

If the question contains a suggestion that the expected answer than the answers provided wouldn’t truly represent the participants thoughts and feelings

8
Q

What will be the impact on the validity of the data if the questions are ambiguous?

A

The validity of the data will be lowered

9
Q

What is content validity

A

Has the researcher measured what he intended to measure

10
Q

If the questionnaire or interview or test is not measuring the intended quantity tent then any score or data will be meaningless and the measure will be classed as lacking what?

A

Content validity

11
Q

What is the ceiling effect

A

If all the questions on a test are easy then everyone will do well i.e. hit the ceiling

12
Q

What is the floor effect

A

If all the questions are too hard everyone will do poorly and hit the floor

13
Q

What are the five ways of assessing the validity

A

Lie scale, face validity, concurrent validity, predictive validity and construct validity

14
Q

What is a lie scale?

A

A lie scale is a way to assess whether people are telling the truth so a few questions act as truth detectors. If the answer to those questions are unnaturally positive then the live scale may have a high result and cause you to be sceptical about the answers on the rest of the questionnaire

15
Q

Give an example of a truth detector?

A

Are you always happy? Are you always positive?

16
Q

What is face validity?

A

Base solidity concerns the issue of whether a self-report measure looks like it is measuring what the researcher intended to measure.

17
Q

What is concurrent validity

A

What is concurrent validity? This can be established by comparing performance on a new self-report measure with a previously validated one on the same topic - if the new measure produces a similar outcome as the older one then this demonstrates the concurrent validity of the new measure

18
Q

What is predictive validity

A

Their score would predict success on other related measures e.g. an intelligence test. Therefore we can check this out as a means of assessing the predictive validity of a measurement

19
Q

What is construct validity

A

This is assessed by looking at the underlying constructs of a test. For example a questionnaire on aggression would need to reflect various key theoretical views in order to be valid

20
Q

How do you improve the validity

A

The test would need to be revised to produce a better match between scores on the new test and an established one
