Q

Process of peer review:

A

1) University sends completed research to another psychologist working in similar field
2) Considered for publishing in psychological journal if high enough quality (standards dependent on journal eg. Nature and Science is very prestigious so more challenging to meet)
3) Research panel considers peer reviewers’ views
4) Poor quality researcg returned to researcher for modification

Q

What type of peer review usually occurs, what is this and what is the advantage of this?

A
  • Double blind peer review

Q

What is one disadvantage of academic journals and how is this problem overcome?

A
  • Physical copies + online subscriptions are expensive (many unis only buy few physical copies a yr)
  • General public/Less well-off unis may not have access
  • Process called ‘Open access’

Q

What is Open Access and how does it work?

A

Open Access = New knowledge can be viewed online by scientific community and general of public
1) Good quality work is published
2) Readers decide its validity, leave comments/ rate articles/ ranked by peer review

Q

Give one disadvantage of using online peer review

A

There can be people who only want to be hateful and do not give useful input to research

27
Q

Process after psychological work has been published:

A

1) Research is disseminated internationally
2) New ideas can develop
3) Reputation of researcher increased and could gain funding
4) Uni looks good + will receive more money as they may receive more gov grants for research

28
Q

What are the 3 functions of peer review according to one body (what is this)?

A

1) Allocation of research funding –> Public bodies like Medical Research Council can the process to decide whether the research will be useful as research is being paid for by charitable bodies/govs
2) Publication of research in academic journals –> Prevents publication of irrelevant findings, improves quality of research, increases probability of errors being detected
3) Assessing research rating of uni departments –> quality of research used to give rating

29
Q

Overall what are the advantages and disadvantages of peer review?

A

+ Neutral and non-biased esp w/ double blind peer review
+ Provides a way to check validity and credibility of research
+ Involves specialist psychologist, who will have experimental knowledge
- Can be unfair as connections between psychologists can result in favouritism for some unis
- Can be unfair as some journals are easier to publish work in compared to others
- Groundbreaking research could be rejected purely due to poor presentation

30
Q

Give one example where social influence was used to change people’s behaviour and attitudes

A
  • Montana had a problem w/ alcohol related car crashed among 21-34 year olds
  • 92% of this age group believed majority of their peers drove after drinking, even though the percentage was only 20%

Q

What purpose have similar campaigns been used for?

A
  • Reducing smoking
32
Q

How does changing people’s behaviour and attitudes with social influence help the economy?

A

Burden on NHS is alleviated

33
Q

What research was done about the memory and how did this help the economy?

A
  • CI research, improving amount of accurate info for EWT eg. Gieselman et al (1984)
  • Less money spent on wrongful arrests and less police time wasted
34
Q

How does research into attachments help the economy?

A
  • Shown importance of role of father eg. Schaffer and Emerson (1964)

37
Q

How has research on psychopathology, effective drug therapies and groundbreaking findings help the economy?

  • Groundbreaking findings: Encourage investment from overseas
38
Q

What are the limitations of providing more effective treatments for the economy?

A
  • New therapies could be more expensive than old ones
  • Significant financial burden to NHS
39

Data are ordered in some way eg. liking, rank

41
Q

Interval (continuous) data:

A

Data measured using units of equal intervals eg. miles, centimetres

42
Q

A
  • Lots of detailed data
  • High in validity and measures concepts in aim
47
Q

Disadvantages of qualitative data:

  • Unreliable, as it is unlikely the same results would be gained
  • Difficult to generalise as you may be quite subjective
48
Q

Primary data (+ limitation):

A
  • Info collected directly from first-hand experience by researcher
  • Provides exact type of data researcher is looking for
    Limitation:
  • Takes a lot of time and effort to collect
49
Q

A
  • Info collected for another purpose by another researcher eg. gov stats
    Limitation:
  • Substantial variation in quality and accuracy of data
50

  • Combination of results from a number of studies on one topic to provide an overall view
  • Prone to publication bias –> researcher may choose to exclude negative or non-significant results
51
Q

Measure of central tendency (+ examples):

A
  • Central values for a set of data
  • Mean
  • Median
  • Mode
52
Q

Advantage of using the mean:

A

Takes all scores into account

53
Q

Disadvantage of using the mean:

A

Can be distorted by a single extreme value

54
Q

Advantage of using the median:

A

Unaffected by extreme scores

55
Q

Disadvantage of using the median:

A

Can be unrepresentative as not all scores are used in calculation

56
Q

Advantage of using the mode:

A

Unaffected by extreme scores

57
Q

Disadvantages of using the mode:

A

Does not provide any info about other scores in data set

58
Q

Measure of dispersion (+ examples) :

A
  • How spread out the items are
  • Range
  • Standard deviation
59
Q

Range calculation:

A
  • Difference between highest and lowest
  • Add 1 (to account for rounding done by researchers)
60
Q

Advantage of using the range:

A

Quicker to calculate than standard deviation

61
Q

Disadvantage of using the range:

A

Easily distorted by extreme values

62
Q

Standard deviation:

A

Average amount score differs from mean

63
Q

Advantage of using the standard deviation:

A

Takes all scores into account

64
Q

Disadvantage of using the standard deviation:

A
  • More difficult to calculate
