Q

Behavioral categories

A

An observational techniques wherein participants’ possible behaviors are separated into more specific components. This allows for operationalisation of the behavior. For example splitting aggression into categories of ‘swearing’ and ‘punching’.

26
Q

Confounding variable

A

A type of extraneous variable that is related to the independent variable in the experiment. For example, if you were testing the effects of anxiety on memory recall, the relative levels of sensitivity to anxiety-inducing stimuli would be a confounding variable.

Q

counterbalancing

A

To make half of the participant sample experience the different conditions of the experiment in one order, and the other half of the participants complete it in the opposite order.

29
Q

Demand characteristics

A

Changes in the participants’ behavior to comply with the hypothesis of the researcher.

30
Q

Dependant variable

A

The variable that changes in response to manipulation of the researcher, that is being measured for the experiment. For example, if you were testing the effects of anxiety on memory recall, memory recall would be the dependant variable.

31
Q

Directional Hypothesis

A

A Hypothesis that specifies the direction of the relationship of the experiment e.g. coffee will have a positive effect on the reaction time of participants

32
Q

Ecological Validity

A

How well results from a test can be applied to real life

33
Q

Event Sampling

A

An observational technique wherein an observer records every time a particular behavior or “event” occurs, usually in the form of a tally chart

34
Q

Extraneous variable

A

Variables other than independent variable that have an affect on the dependant variable. For example, if you were testing the effects of anxiety on memory recall, the intelligence levels of the participants could be extraneous variables.

35
Q

Face Validity

A

if a test appears to be valid at first appearances, in spite of how well it works in a real world scenario.

36
Q

Falsifiability

A

The quality of being able to be proven wrong

37
Q

Generalisation

A

To attribute information from a sample to the rest of the population

38
Q

Hypothesis

A

The prediction of the outcome of the experiment.

39
Q

Independent groups

A

An experimental design wherein different participants are involved in different conditions of the experiment. For example, using two different groups of people to test the effect of music on memory recall, with one group memorising during music playing and the other silence.

40
Q

Independent Variable

A

The variable that is manipulated by the researcher to observe its effects on the dependant variable.

41
Q

Inter observer reliability

A

Multiple investigations gather information separately during an observation and compare their data for similarity after.

42
Q

Investigation effects

A

Unconscious changes in the investigators behavior to comply with the hypothesis of the investigation

43
Q

Matched pairs design

A

An experimental design wherein participants in different conditions of the experiment are matched on certain variables to reduce the effect of participant variables.

44
Q

Non directional Hypothesis

A

A hypothesis that does not specify the direction of the relationship of the experiment

45
Q

Objectivity

A

Empirical; something that is not influenced by personal feelings

46
Q

Open questions

A

A type of question that requires answers that are longer than ‘yes’ or ‘no’

47
Q

Operationalisation (of variables)

A

To clearly state and objectivity a variable. For example Instead of measuring ‘aggression’, researchers would convert it into observable categories like ‘punching’ and ‘kicking’.

48
Q

Opportunity sampling

A

a sampling technique that involves obtaining a sample via anyone that is available from the population at the time of collecting the sample. For example, handing questionnaires out to people outside a shopping mall

49
Q

Paradigm

A

a basic concept; a well accepted core belief.

50
Q

Paradigm Shift

A

When previously accepted core concepts in a science are changed, usually due to the emergence of new evidence.

51
Q

Peer review

A

The assessment of work by other people with similar levels of expertise in that field, to provide an unbiased expert opinion of said work.

52
Q

Pilot Studies

A

Preliminary/trial studies carried out to ensure the clarity of the study itself. For example, using a pilot questionnaire on a sample of people that give feedback on the clarity of questions.

53
Q

Population

A

The group represented by a sample

54
Q

Random allocation

A

To allocate participants to seperate conditions using some sort of randomisation technique. For example, using a computer to randomly generate groups fo condition A and B.

55
Q

Random sampling

A

A sampling technique that involves randomly generating participants from the population by any randomisation technique.

56
Q

Reliability

A

Essentially replicability; the extent to which the test can be repeated and gather similar results

57
Q

Repeated measures

A

An experimental design wherein the same participants undergo all the conditions of the experiment

58
Q

Replicability

A

How easily a test can be repeated

59
Q

sample

A

A smaller group that aims to be representative of the population

60
Q

Standardisation

A

Keeping the experimental methods as identical as possible

61
Q

Stratified sampling

A

A sampling technique that involves establishing sub-groups (strata) within the population investigated and picking participants to create a representative sample

62
Q

Systematic sampling

A

A sampling technuque that involves establishing a method to pick participants evenly distributed through the population.

63
Q

Temporal Validity

A

How well results form a test can be applied across time periods

64
Q

test-retest reliability

A

Completing a test multiple times and comapring the scores for similarity

65
Q

Time sampling

A

An observational technique where an observer only records specific behaviors in specific time intervals

66
Q

Validity

A

Truthfulness;the extent to which a test measures what it aims to measure, i.e. uncontrolled extraneous variables reduce validity because they affect what is supposed to be measured

67
Q

Volunteer sampling

A

A sampling technique that involves using participants that volunteer to take part in the study, provided they meet the inclusion criteria.

68
Q

Nominal

A

A level of measurement thats refers to variables that can be counted in whole numbers, to indicate frequency

69
Q

Ordinal

A

A level of measurements that refers to variables that can be placed on a scale of relative importance i.e. i order.

A

A type of data analysis that aims to identify, report and analyse recurring concepts.
