Unit 2 AoS3 Flashcards
How do scientific investigations develop understanding of influences on perception and behaviour?
Define sample:
smaller group of research participants selected from a larger group of interest
describe voluntary participation
must be willing and free to participate
what are ethical considerations in an experiment?
voluntary participation, informed consent, withdrawal rights, debriefing, deception, confidentiality
what is the acronym for remembering ethical considerations?
very inspiring women don’t drink coffee
describe confidentiality
privacy must be protected and no privateor identifiable info can be used or published
describe informed consent
must be informed of the nature and purpose of the study, including any risks
What is a between-subjects design (independent groups)
one group is exposed to one experimental condition, and another group is exposed to a different experimental condition
decribe withdrawal rights
are able to leave study at any time and can withdraw results from the study
describe deception
must know the purpose of the study unless it will influence results and then must be adressed after experiment is finished
list some extraneous variables
participant-related variables, non-standardised instructions and procedures, order effects, placebo effects, and experimenter effects.
what is a within-subjects design (repeated measures)?
the same group of participants are exposed to/participate in both experimental conditions
What is the title for this experiment?
Does food packaging influence taste perception?
Research hypothesis
A testable prediction of the relationship between two or more variables (events to characteristics).
Research method
A particular way of conducting a research study (investigation) to collect accurate and reliable data on a topic of interest.
Observational study
Involves collection of data by watching and recording behaviour as it occurs.
Quantitative data
Numerical information on the ‘quantity’ or amount of what is being studied; that is, how much of something there is.
Qualitative data
Information about the ‘qualities’ or characteristics of what is being studied.
Questionnaire
A written set of questions designed to draw of self-report information from people on a topic of research interest.
Population
The entire group of research interest from which a sample is drawn and to which the researcher will seek to apply (generalise) the results of their investigation.
Conclusion
A decision about what the results obtained from a research study mean.
Sample
A subsection or smaller group of research participants selected from a larger group of research interest.
Random sampling
A sampling procedure that ensures every number of the population of research interest has an equal chance of being selected to be a part of the sample.
Self-report
The participant’s written or spoken responses to questions, statements or instructions presented by the researcher.
Generalisation
A decision about how widely the findings of a research study can be applied, particularly to other members of the populations from which the sample was drawn.
Observational study
Involves collection of data by carefully watching and recording behaviour as it occurs.
