Key Terms Flashcards
Lab experiment
The IV is manipulated by the researcher and the experiment is carried out in a lab or other contrived setting away from the participants normal environment
Field experiment
The IV is manipulated by the experimenter but this time the experiment is carried out using participants in there normal surroundings.
Quasi experiment
The IV is naturally occurring, not manipulated by the researcher.
Repeated measures
This involves using the same people in each condition.
Independent measures design
This involves using different people in each condition.
Matched pairs design
This involves using different people in each condition but an attempt is made to make participants as similar as possible on certain characteristics.
Participant variables
Are characteristics of the individual participant that may influence results
Situational variables
Are any features of the research situation which influences a participants behaviour and therefore the results.
Order effects
If doing the same activity twice participants may do better the second time because practise or worse because of boredom.
Demand characteristics
These are cues that let the participant know the true meaning of the experiment resulting in them changing their behaviour.
Alternative hypothesis
This predicts how one variable is likely to affect another variable. It predicts that the IV will affect the dv.
A null hypothesis
Predicts that the IV will not affect the DV.
A two tailed hypothesis
Predicts that the IV will have a significant affect on the DV but doesn’t predict the direction in which the experiment will go.
A one tailed hypothesis
This predicts that not only will the IV have a significant effect on the DV but also the direction in which the effect will go in.
Operationalisation
Refers to the process of making variables physically measurable or testable.
Target population
The group of people the researcher is interested in studying.
Sampling methods
The different ways in which researchers can obtain a sample of people from within the target population to take part in their study.
Sample
The actual group of people used the the research
Self selecting
This is when people volunteer to take part in the study. Often adverts will be distributed which contain details about be research.
Opportunity
A sample is collected by using people from the area around you.
Abstract
A summary of a piece of research that outlines the aim, method, participants, results, and conclusions presented at the start of the research paper.
Altruistic behaviour
selfless behaviour; behaviour that is unselfish in its concern for others.
appendices/appendix
a section that may appear at the end of a research paper which contains any list of materials, calculations, raw data, and anything else the reader needs to fully understand and research.
biased sample
a sample that is not representative of its target population or of people in general.
biomedical
a model of health that seeks to explain health in terms of single-factor physical causes.
bystander apathy
where people do not offer help to a victim when others are present.
case studies
where a small group of participants are studied in depth; often the participants are unusual in some way.
castration complex
part of the oedipus complex: a boy’s fear, after seeing a naked female for the first time, the he will lose his penis.
ceiling effect
the point at which the participant cannot achieve a higher score, eg. on a test, although they have the capability to do so.
classical conditioning
the principle that people learn to associate two stimuli.
closed/forced answer questions
questions with a limited range of responses to choose from.
coding frames
groups of classifications that show how qualitative data has been converted in numerical (quantitative) data for analysis.
concurrent validity
Where a test is validated against an existing measure. for example, it we know that X cause Y, and the new test also shows that X causes Y, then we know that the new test has validity.
conditions
in an experiment, the situation under which is undertaken. Usually there is a control condition and an experimental condition and results from each condition are compared to determine the effect of the independent variable on the dependent variable.
confidentiality
a set of rules to protect the privacy of participants by not associating their names with their responses.
consent
an ethical requirement that ensures that all participants have agreed to take part in the procedure/experiment/research.
construct validity
where a test or study measures the actual behaviour it sets out to measure.
content analysis
where researchers analyse text to look for patterns and repetitions.
controlled observation
an observation that controls all the possible factors which might alter the behaviour.
controls
the aspects of research that are kept the same for each condition to ensure that the independent variable is the only variable effecting the dependent variable.
