Q

Advantage and disadvantages of lab experiments

A

Advantage: Easy to replicate and you can be certain that the DV is affected by the IV

Disadvantage: low ecological validity as its artificial setting and the participants may behave in a way they think the experiments want them to behave in

Q

Advantage and disadvantage of field experiments

A

Advantage: higher ecological validity, behaviour more likely to be normal

Disadvantage: lack of control-extraneous variables may affect the the DV not the IV, ethical issues- not being aware of the experiment

Q

Advantage and disadvantage of quasi experiments

A

Advantage: can study effects of variables that you can’t manipulate p, high ecological validity

Disadvantage: difficult to replicate due to naturally occurring IV, lack of control over extraneous variables may affect results

Q

What are the strengths and weaknesses of the situational side of the debate?

A

Ad:can alter behaviour by altering the situations that create it
Helps us to understand why people behave the way they do

Dis:socially sensitive-used as an excuse to explain away bad behaviour
Reductionist misses out the individual factors

49
Q

What is the nature side of the nature nurture debate?

A

Suggests we are a product of out genetic inheritance, we behave due to the factors innate within us

50
Q

What is the nurture side of the nature nurture debate?

A

Suggests we are products of our upbringing, we behave due to the experiences and personal encounters we’ve had

51
Q

What are the strengths and weaknesses of nature side of the debate

A

Strength: potentially useful-points towards genetic modification or other biological interventions, not ethnocentric as biological factors affect people in same way anywhere

Weakness: limited usefulness, not possible to change persons nature, reductionist:misses out nurture impact, socially sensitive if identifying a problem that someone can’t change about them selves

52
Q

What are the strengths and weaknesses of the nurture side of the debate?

A

Can be useful, suggests ways to change behaviour by changing how child is brought up

Reductionist- missing out impact of nature, might be ethnocentric as countries vary in how people are brought up, socially sensitive leading children to blame parents for how they are brought up

53
Q

What debates link to nature nurture debate

A

Bandura

Blakemore and cooper

54
Q

What core studies relate to usefulness of research?

A

Loftus and Palmer-leading questions

Bandura-children’s behaviour

55
Q

What are the benefits and drawbacks

of usefulness of research

A

Benefit: positive practical applications improve quality of lives, more likely to get funding if has practical applications, improve credibility as academic subject

Drawbacks:put to bad use-socially negative uses, if two lawyers make use of same psychological insight then usefulness of research is cancelled out, if research is deemed to be useful then guidelines may be broke.

56
Q

What is the reductionist side of the reductionist holism debate?

A

Human behaviour is explained by one single point eg hormones alone

The research should be extremely controlled to establish cause and effects

57
Q

What is the holism side of the reductionist holism debate?

A

Human behaviour is viewed as the product of different influences which all interact

Research should be case studies that capture all different influences on behaviour

58
Q

What are the strengths and weaknesses of reductionism

A

Strength:Psychological research can be more scientific as test impact of one thing at a time , More accurate conclusions

Weakness: human behaviour too complex to narrow down to single factor explanations, lack ecological validity as highly controlled experiments

59
Q

What are the strengths and weaknesses of the holism debate?

A

Strength: more complete explanations of complex behaviours, research isn’t limited to a single area of perspective

Weakness: difficult to pin down the most significant effect, only be verified by separating the factors out (reductionist) and testing one by one to confirm they have an impact

60
Q

What does a subject have to be in order to be classed as a science? 3 things

A

1) objective - factual
2) replicable - repeatable
3) falsifiable - can’t prove wrong

61
Q

What studies link to psychology as a science?

A

Are scientific - milgram and piliavin

Not - FREUD

62
Q

What are the benefits and drawbacks of research being scientific ?

A

Benefits: quantitative data-easily analysed, less vulnerable to being bias by researcher, lab experiments allow cause and effects to be inferred, controlled so replicable

Drawbacks: lack qualitative data, research is reductionist as test impact of single factor, lab experiments reduce ecological validity

63
Q

What is socially sensitive research?

A

Areas that could have a negative effect on either the people being researched or the class of people that they represent.

64
Q

Benefits and drawbacks of socially sensitive research?

A

Benefit: answer important questions that improve our understanding of human behaviour, lead to practical applications that improve quality of people’s lives

Drawbacks: involves potential harm being caused to participants in the research, lead to people beyond survey being stigmatised, insights it provides used negatively

65
Q

What core studies relate to socially sensitive research

A

Yerkes and Gould - isolates different classes and ethnic minority’s
Bandura - imitating reflects on parent are they bad parents? Offensive

NOT SOCIALLY SENSITIVE IS COGNITIVE AREA
Moray and loftus n Palmer - same for everyone due to biological factors

66
Q

What is the free will side of the free will determinism debate?

A

Proposes that behaviour is the product of our own choice and are ab,e to choose how we behave

67
Q

What is the determinism side of the freewill determinism debate?

A

Behaviour is caused by factors outside of our control, could be genetic or to do with upbringing or physical/social circumstances

68
Q

What core studies fit into the freewilll determinism debate?

A

Determinism-Bandura, loftus and Palmer

Freewill - milgram 35% of participants chose not to carry on

69
Q

What are the strengths and weaknesses of freewill Sid elf the debate?

A

Strength :Not socially sensitive, and useful as people can be help accountable for their behaviour

Weakness: unscientific, just explain is as we can’t any other way, socially sensitive as people may find it uncomfortable being told they are responsible for their actions

70
Q

What are the strengths and weaknesses of determinism side of the debate?

A

Strength:open to positive uses if we know what causes wanted behaviour we can make it occur again, scientific as explanations come from controlled experiments in which cause and effect is established

Weakness:negative uses-get people acquitted , reductionist as behaviour isn’t explained so easily, socially sensitive when being told not in charge of behaviour

71
Q

What is internal validity

A

Whether the experiment was an accurate test of what’s being tested

Research doesn’t have lots of extraneous variables and it’s the effect of independent variable on dependent variable that’s being measured

72
Q

76
Q

What is measures of dispersion

A

How spread out scores are

Range, variance, standard deviation

77
Q

What is variance

A

Measures how spread out they are
Variance of zero-indicates values are all identical
Large variance-indicates data very spread out around the mean

78
Q

How do you calculate the variance

A

1-work out mean
2-for each participant, subtract the mean from their score this gives the difference
3-square the difference
4-work our mean of all d^2

79
Q

Chi square. Binomial sign. X

Mann Whitney. Wilcoxon signed. Spearman rho

82
Q

What’s a type 1 error

What’s a type 2 error

A

1-when null hypothesis is falsely rejected - false positive, there isn’t a genuine effect

2-when null hypothesis is falsely accepted - false negative, there is a genuine effect

83
Q

What’s Face validity

A

How good test or research looks to be testing what it it’s meant to be t sting

84
Q

What’s construct validity

A

Test or study measures the actual behaviour it sets out to measure
Eg test for intelligence shouldn’t assess general knowledge

85
Q

What’s concurrent validity

A

Test or research gives same results as another test or study which claim to measure the same behaviour

86
Q

What’s criterion validity

A

Refers to how much one measure predicts the value of another measure
Eg IQ test predicting school success

87
Q

A

How accurately the test or study measures behaviour in the general population

88
Q

90
Q

What is social desirability bias

A

Where participants try to present an image of themselves as being good members of society-not

91
Q

What’s socially desirable

A

Responses that the participants feel will please the researcher and present them in good light

92
Q

What’s inter rater reliability

A

Where two observers consistently rate or observe the same behaviour and the two sets of ratings are correlated to ensure that observations are not subjective

93
Q

What’s a participant observation

A

Where the researchers or observers are part of or pretending to be part of the group that they are observing

94
Q

What’s a non participant observation

A

Where observer is not a member of the group being studied

95
Q

What’s a structured observation

What’s an unstructured observation

A
  • impose structure to meet aim of observation (what behaviours in particular that they are interested in recording )
  • continuously record and observe everything
96
Q

What is a covert observation

A

Where the participant doesn’t know they are being observed

97
Q

What is an overt observation

A

Where the participant knows that they are being observed and have given their consent or been made aware of being observed because of observers presence

98
Q

What’s a strength and weakness of unstructured and structured observations

A
  • lots of detail, however hard to reveal anything significant and hard to summarise and make comparisons
  • allows for comparisons to be made, however when only settle on looking at a few certain behaviours may miss something very important.
99
Q

Strength and weakness of naturalistic and control observations

A
  • May see natural normal behaviour but extraneous variables may influence behaviour
  • situation is artificial so not natural behaviour, but no extraneous variables affecting behaviour-high construct validity
100
