A

where one variable decreases the other variable decreases

57
Q

what are the 4 main reasons we have ethical guidelines

To protect the reputation of psychology
To build trust between the researcher and the participants
To protect participants
To further our understandings on human behaviour

58
Q

What are the three reasons breaching an ethical guideline can be justified by

A

if the research furthers our understanding of human behaviour
if the research predicts human behaviour
is the findings lead to effective treatment and/or positive social change

59
Q

variables

A

anything that can be controlled or measured

60
Q

examples of variables

A
time
age 
lightening
stress levels
gender
height
weight

A

the variable being tested by being changed/controlled and is assumed to have a direct effect on the dependent variable

62
Q

dependent variables

A

the variable being tested or measured in an experiment and is dependent on the independent variable

63
Q

what does it mean to operationalise a variable?

A

to clearly define a variable in terms of how it can be measured
for example studying aggression by measuring shouting

64
Q

what is standardisation

A

using exactly the same formalised procedures for all participants in a research study

65
Q

extraneous variables are

A

Extraneous variables are all variables, which are not the independent variable, but could affect the results of the experiment. The researcher wants to make sure that it is the manipulation of the independent variable that has an effect on the dependent variable.

66
Q

confounding variables are

A

A confounding variable, also called a confounder or confounding factor, is a third variable in a study examining a potential cause-and-effect relationship. A confounding variable is related to both the supposed cause and the supposed effect of the study.

67
Q

what is a lab experiment

A

a lab experiment is one that is carried out in a highly controlled environment

68
Q

strengths of lab experiments

A

replicable - can be repeated to find the same or similar results

69
Q

weaknesses of lab experiments

A

artificial
lacks ecological validity - difficult to generalise results outside of the lab
demand characteristics may influence findings
consent deception may be needed

70
Q

what is a natural experiment

A

the researcher does not control the independent variable. they occur naturally

71
Q

what are the strengths of a natural experiment

A

reduced demand characteristics

ecological validity is improved

72
Q

what are the weaknesses of a natural experiment

A

difficult to control confounding variables
difficult to replicate
lackl of consent
confidentiality is breached

73
Q

what is a quasi experiment

A

the

74
Q

what are the strengths of a quasi experiment

A

under controlled circumstances - can be repeated

75
Q

what are the weaknesses of a quasi experiment

A

demand characteristics

confidentiality and consent issues

76
Q

demand characteristics mean…

A

when participants deliberately changes their behaviour to act favorably for the researcher

77
Q

what type of variable is a demand characteristic

A

extraneous variable

78
Q

what are the three things that make an experiment an experiment

A

variables - IV and DV
having controlled variables
cause and effect established

79
Q

aim -

A

the purpose of your investigation

80
Q

hypothesis

A

a prediction testable statement

81
Q

directional hypothesis

A

tells us the direction of the investigation - where the results are going. tells us the difference between the conditions.

82
Q

non - directional hypothesis

A

does not tell the direction of the experiment - tells us there will be a a difference but doesn’t tell us the difference

83
Q

null hypothesis

A

n

84
Q

what does it mean by experimental design?

A

what you want the participants to do - How you intend for the research to be carried out

the different ways in which the testing of participants can be organised in relation to the experimental conditions

85
Q

Name the 3 experimental designs

A

repeated measures
independent groups
matched pairs

86
Q

what are the strengths of repeated measures

A

less participants are required compared to independent groups and matched pairs

87
Q

what are repeated measures?

A

Where the same participants are used in both conditions. The participants switch from taking part in condition A to condition B, where they experience both conditions

88
Q

what are the limitations of repeated measures?

A

order effects - such as demand characteristics may alter results
effects from previous condition may alter results acting as a variable

89
Q

what are three order effects

A

fatigue
boredom
practice

90
Q

How does counterbalancing overcome order effects?

A

Counterbalancing is a technique used to deal with order effects when using a repeated measures design. With counterbalancing, the participant sample is divided in half, with one half completing the two conditions in one order and the other half completing the conditions in the reverse order

91
Q

what are independent groups

A

when participants are randomly allocated into different conditions when partaking in the same research. Each participant only experiences one condition

92
Q

What are the strengths of using independent groups?

A

avoids bias
high internal validation
order effects dont influence

93
Q

what are the limitations of using independent groups?

A

personal characteristic difference between the participants in each condition may reduce results validity
more participants are needed

94
Q

what are matched pairs?

A

where participants are split into two conditions. Each participant in condition A are matched with another participant in condition B by their similarities as a person. An assumption is made in treating two participants as one. Therefore, each participant only experiences one condition.

95
Q

what are the strengths of using matched pairs?

A

order effects and demand characteristics dont influence findings

96
Q

what are the limitations of using matched pairs?

A

matching participants may require a pre - test and so it can be time consuming and finding good matches may be expensive

97
Q

Name 8 things that should be on a consent form

title of project
a clear statement on the purpose of the study
what participants will be asked to do
what data will be recorded
likely discomforts
anonymity and confidentiality assurance
withdrawal assurance

contact details for participants to discuss issues later

98
Q

what is a field experiment?

A

The IV is in a natural, more day setting

99
Q

what are the strengths of field experiments?

A

reduced demand characteristics

ecological validity is improved

100
Q
