Q

Confidentiality

A

the principle, based on a person’s right to privacy, that any information gathered about a participant during research must not be revealed without that person’s consent

Q

Confounding variables

A

extraneous variables whose influence are uncontrolled and vary systematically with the iv, cloud the ability to determine the true relationship between the iv and dv

Q

Controlled variables

A

variables other than the IV that a researcher controls in an investigation, to ensure that changes in the DV are solely due to changes in the IV

Q

Convenience sampling

A

any sampling technique that involves selecting readily available members of the population, rather than using a random or systematic approach

Advantage: time effective
Disadvantage: unlikely to produce representative sample

Q

Counterbalancing

A

arranging the order in which the conditions of a repeated measures experiment are experienced by participants so that each condition occurs equally often in each position

the principle whereby the researcher must explain to participants what the study really involved once it has been completed

Q

Deception

A

researcher should avoid deliberately misleading participants & should provide enough info to let them choose whether they participate
in cases where prior knowledge can confound the results, researcher may misinform participants so they don’t know the purpose of the study
^prevents expectancy effects, providing that adequate debriefing occurs after it has been completed

Q

Controlled experiment

A

a type of investigation in which the causal relationship between two variables is tested in a controlled environment
the effect of the IV on the DV is tested while aiming to control all other variables

Advantages: follows strictly controlled procedure so can be repeated to check results

Disadvantage: often only conducted in a lab so may not reflect real life

Q

Independent variable (IV)

A

the variable for which quantities are manipulated by the researcher, and te variable that is assumed to have a direct effect on the DV

Q

Between-subjects design

A

an experimental design in which individuals are divided into different groups and complete only one experimental condition

22
Q

Types of fieldwork

A
  • direct observations
  • qualitative interviews
  • questionnaires
  • focus groups
  • yarning circles
23
Q

Sample

A

a subset of the research population who participate in a study

24
Q

Generalisable/external validity

A

the ability for a sample’s results to be used to make conclusions about the wider research population

25
Random sampling
any sampling technique that uses a procedure to ensure every member of the population has the same chance of being selected. Advantage: reduces experimenter bias Disadvantage: may be time-consuming
26
Stratified sampling
any sampling technique that involves selecting people from the population in a way that ensures that its strata are proportionally represented in the sample Advantage: likely to produce a representative sample Disadvantage: can be time-consuming & expensive
27
Extraneous variable
any variable that is not the independent variable but may cause an unwanted effect on the dependent variable and therefore influence the results of an experiment
28
Participant related variables
characteristics of a study's participants that may affect the results
29
Order effects
the tendency for the order in which participants complete experimental conditions to have an effect on their behaviour
30
Placebo effect
when participants respond to an inactive substance or treatment as a result of their expectations or beliefs
31
Experimenter effect
when the expectations of the researcher affect the results of an experiment
32
Situational variables
any environmental factor that may affect the dependent variable
33
Non-standardised instructions and procedures
when directions and procedures differ across participants or experimental conditions
34
Demand characteristics
cues in an experiment that may signal to a participant the intention of the study and influence their behaviour
35
Single blind procedure
a procedure in which participants are unaware of the experimental group or condition they have been allocated
36
Double blind procedure
a procedure in which both participants and the experimenter do not know which conditions or groups participants are allocated to
37
Objective data
factual data that is observed and measured independently of personal opinion
38
Subjective data
data that is informed by personal opinion, perception, or interpretation
39
Accuracy
how close a measurement is to the true value of the quantity being measured
40
Precision
how closely a set of measurement values agree with each other
41
Systematic errors
errors in data that differ from the true value by a consistent amount
42
Random errors
errors in data that are unsystematic and occur due to chance
43
Repeatability
the extent to which successive measurements or studies produce the same results when carried out under identical conditions within a short period of time
44
Reproducibility
the extent to which successive measurements or studies produce the same results when repeated under different conditions.
45
Validity
the extent to which psychological tools and investigations truly support their findings or conclusions
46
Internal validity
the extent to which an investigation truly measures or investigates what it claims to
47
External validity
the extent to which the results of an investigation can be applied to similar individuals in different settings
48
Ethical concepts
- Beneficence - minimising harm - Integrity - Justice - Non-maleficence - avoiding harm - Respect
49
Ethical Guidelines
- Confidentiality - informed consent procedures - deception - debriefing - voluntary participation - withdrawal rights
50
Experiment
research method used to systematically test a hypothesis, conducted under carefully controlled conditions to measure causal relationships of an iv on a dv
