Unit 2 exam Flashcards
Observational study
a type of study in which data is collected through careful monitoring of participants
Case study
an in-depth study of an individual or a very small group of individuals
Longitudinal study
a type of investigation in which data is gathered from participants over an extended period of time, and the
participants are followed up after specific time intervals
Cross sectional study
when data is collected from participants from different segments of the population (pre-existing cohorts) to represent a ‘snapshot’ in time
Independent group design
an experimental design in which participants are split into two or more groups; typically a control group and an experimental group/s
Repeated measures design
an experimental design in which the same participants are in every condition of the experiment
Matched participant design
an experimental design in which participants are paired based upon relevant characteristics, where one member of the pair is tested in one condition, and the other member is tested in the other
Convenience sampling
when a sample is selected using the quickest and easiest means possible, selecting people who are readily available from the population
Random sampling
when every member of the population has an equal chance of being selected for the sample
Stratified sampling
when the population is divided into groups based upon relevant characteristics, and participants are selected from each group in proportion to how they appear in the population
Extraneous variables
variables other than the independent variable that may produce unwanted results in an experiment
What is replication and why would it be used?
The purpose of replication is to determine whether results from an experiment can be reproduced and are hence reliable
What is synaesthesia?
Synaesthesia is a perceptual experience where the stimulation of one sense creates a simultaneous stimulation of a difference sense without replacing the initial sense
What is an example of synaesthesia?
Seeing a distinct colour whenever each letter of the alphabet is viewed
What are the factors that influence conformity?
1 Informational influence
2 Unanimity
3 Group size
4 Culture
5 Deindividuation (anonymity in a group)
6 Deindividuation (shift in attention)
What is Informal influence? - influence conformity
Conformity arises when information is needed because the person is unsure of what to do
What is unanimity? - influence conformity
Conformity is greater when all of the other members of a group are in agreeance
What is group size? - influence conformity
Conformity increases as group size increases but only up to group sizes of eight before levelling out
