Q

Asking people questions about their attitudes, behaviour etc.

Reveals attitudes or self-reported behaviours of a large sample of individuals.

A

Survey research

16
Q

Produce consistent measurements over time, or amongst items in a scale of measurement.

Refers to a measure’s ability to produce consistent results.

A

Reliable

17
Q

Actually measure the variable of interest; or is a measure used for the purposes for which it is designed.

It refers to the measure ability to assess the variable it is supposed to assess.

A

Valid

18
Q

Does the test give similar values if the same participant takes it two or more times?

A

Test- retest reliability

19
Q

Different items that measure the same variable should produce similar answers- be consistent.

A measure is …… If several ways of asking the same question yield similar results.

A

Internal consistency

20
Q

Two testers who rate the same person on the same variable, should give similar ratings to the participant.

A

Integrated reliability

21
Q

The scientific approaches 3 main goals?

  1. summarises data produced in a way that makes the events and the relationship between them easily understandable.

Description

Q

The scientific approaches 3 main goals?

  1. Using outcome of research to identify what is likely to occur in the future
A

Prediction

23
Q

The scientific approaches 3 main goals?

  1. Identifying the causal(underlying) factors that led to the results found
A

Understanding

24
Q

Manipulated by the experimenter, which is outside the participants control.

The aim is to assess the impact of these manipulations on the way participants respond.

A

Independent Variable(IV)

25
Q

Participants responses.

Is the response the experimenter measures to see whether the experimental manipulation had an effect.

A

Dependant Variable (DV)

26
Q

A group that is similar to the experimental group, except that it has not been exposed to the treatment.

A

Control Group

27
Q

Shares the logic and many features of the experimental method but do not allow as much control over all relevant variables.

A

Quasi-experimental designs

28
Q

An in-depth observation of one person or a small group of individuals.

A

Case study

29
Q

High values of one variable are associated with low values of the other variable.

A

Negative Correlation

30
Q

High values of one variable are associated with high values of the other variable.

A

Positive correlation

31
Q

Informed consent

Maintain participants welfare

Voluntary participation

Ensure confidentiality

Avoid deception

Fair and humane treatment of animals

Gain appropriate ethics approval

A

Code of ethics

32
Q

Measures electrical activity towards the surface of. The brain(near the skull).

A

Electroencephalogram (EEG)

33
Q

Uses computer programs to convert the data taken from brain-scanning devises into visual images of the brain.

A

Neuroimaging techniques

34
Q

Rotates an X-ray tube around a persons head producing a serious of X-ray pictures.

A

CAT Scan

35
Q

Is a neuroimaging technique that provides that produces similar results without using X-rays

A
