18
Q

Stratified sampling strengths and weaknesses

A

+ representative of target population

  • time consuming finding participants
19
Q

Opportunity sampling

A

Using participants who are available at the time.

Through:
• passers-by

20
Q

Opportunity sample strengths and weaknesses

A

+ fast and simple

  • limited control over recruitments
  • not everyone has an equal chance
21
Q

Volunteer sampling

A

Self-selected participants who volunteer to take part after having heard of the existence of this study.

Through:
• adverts (newspapers, tv, student common room)

22
Q

Volunteer sampling strengths and weaknesses

A
  • no control over recruitments
  • certain type of participants might take part making it less representative
  • sample bias

+ pretesting volunteers reduces sample bias
+ fast and simple

23
Q

Structured interview

A

Standardized interviews consisting of the same question in the same order so that all respondents are asked the same questions in the same way

• closed questions

24
Q

Attitude scales

A

Range of different options to answer

  • likert scale
  • ranked scale
25
Q

Likert scale

A

Respondants rate their opinion

Example:

“Naughty children should be smacked”

   5            4            3              2                    1 S. agree | Agree | Neutral | Disagree | S. Disagree
26
Q

Social desirability

A

When a respondent does not give a genuine answer instead giving one that depicts them in a positive light.

27
Q

Self-report Data

A

A method to gather information about how people feel, their attitudes and opinions, personality types and other traits.

28
Q

Types of self-report methods

A
  • surveys
  • interview
  • questionnaires
29
Q

Questionnaire

A

Designed to gather a large amount of data by accessing a large sample

30
Q

Measures of central tendency

A
  • mean
  • median
  • mode
31
Q

Measures of dispersion

A
  • range

- standard deviation

32
Q

CAT Scans

A
  • multiple X-rays
  • produced cross-sectional image of brain
  • create 3D image of brain
  • highlights brain damage/ tumours
33
Q

Evaluate the use of CAT scans

A

+ easy
+ accurate

  • do not show brain activity
  • harmful
34
Q

PET scans

A
  • 3D computer generated images
  • radioactive injected tracer - releases Gamma rays
  • high activity = more gamma rays
  • used to find out active parts of the brain
35
Q

fMRI Scans

A
  • through oxygen
  • detects changes of blood-oxygenation and flow
  • active areas use more oxygen
  • used to investigate: learning, emotion, memory
  • electromagnets used to detect blood changes
36
Q

Evaluate the use of fMRI scans

A

+ shows brain activity
+ non-invasive (nothing injected)
+ non-harmful (no radiation)
+ more specific

  • people with mental implants/ pacemakers cannot get fMRI scans
  • claustrophobic people might have problems
  • more expensive
37
Q

Brain scanning techniques

A
  • CAT scans
  • PET scans
  • fMRI
40
Q

Evaluate the use of PET scans

A

+ raine et al. used it (evidence)
+ shows non functioning areas of the brain

  • harmful (radioactive)
41
Q

Experimental designs

A
  • independent groups design
  • repeated measures design
  • matched pairs design
42
Q

Independent Groups Design

A

Each condition has completely different groups of people

43
Q

Repeated Measures Design

A

Everyone is in both experimental and control group

44
Q

Matched Pairs Design

A

Different participants in each condition BUT matched on important characteristics
