Co-variables
definition
Two or more measured variables in a correlation
Laboratory experiment
definition
Field experiment
definition
Natural experiment
definition
An investigation looking for a causal relationship in which the IV cannot be directly manipulated
* effect of an existing difference or change is investigated
* cannot manipulate variables - variables are naturally occuring
Standardisation
definition
The practice of keeping the procedure for each participant in a study exactly the same, to ensure that measured differences in the DV are likely to be due to the IV
Controls
definition
Ways to keep potential confounding variables constant, to ensure measured differences in the DV are likely to be due to the IV
Replication
definition
Keeping the procedure and materials exactly the same between studies
Operationalisation
definition
The practice of clearly describing a variable such that it can be measured/quantified and accurately manipulated so that the study can be replicated.
Ecological validity
Research methods
How generalisable the study’s findings are to other situations or settings.
Population validity
Research methods
How well a study’s sample represents other populations or groups.
Explain what is meant by
debriefing
Ethics: Human Participants
Explain what is meant by
right to withdraw
Ethics: Human Participants
participants can leave the research experiment before it starts, during the process or after the process has ended
Explain what is meant by
privacy
Ethics: Human Participants
participants privacy must not be invaded and they have control over what information is published
Explain what is meant by
confidentiality
Ethics: Human Participants
participants’ identities must not be revealed to the public
minimising harm and maximising benefits
definition
ensuring that participants are not physically or psychologically harmed by the research process
Explain what is meant by
valid consent including informed consent
Ethics: Human Participants
participants are made aware of the benefits and risks of the research, and give unambiguous consent
Explain what is meant by
lack of deception
Ethics: Human Participants
participants should be aware of all the details of the experiment; if deception is necessary, they must be debriefed afterwards
species and strain
definition
species must be least likely to become distressed;
whilst being able to fulfill the requirements of the study; endangered species must not be used
Explain what is meant by
numbers
Ethics: Non-human participants
The smallest number of animals possible should be used while being enough to achieve reliable results
Numbers
Explain what is meant by
anaesthesia, analgesia, euthanasia
Ethics: Non-human participants
Anaesthesia, analgesia, euthanasia
deprivation and aversive stimuli
definition
pain and distress
definition
Any physical/psychological pain and distress must be avoided.
Any adverse effects on animals must be recognised and assessed, with immediate action taken wherever necessary
replacement
definition
Researchers should consider replacing animal experiments with videos or computer simulations
housing
definition
