Between Groups
This type of research allows us to find causal relationships between variables
What are experiments?
This type of research studies physical evidence left behind by behaviors
What is Physical Trace?
A type of within-subjects design, where measurements are taken on a number of occasions, and not necessarily following a treatment or manipulation
What is repeated-measures?
An experience where one condition affects performance in subsequent conditions
What are sequence effects?
This term refers to one independent variable in a factorial design
what is a factor?
A way to ensure that participants are equally likely to be assigned to any group in a study
What is random assignment?
records or documents that are updated on some regular basis.
What is Continuous data?
an account or statement created for others to read
What is a Record?
A sequence effect where participants perform better during later treatment conditions because they've had time to improve
What is a practice effect?
The effect of each of the independent variables on the dependent variable
what is the main effect?
An experimental design where both the participants and the experimenter do not know which group participants are in
What is a double blind study?
The idea that not every physical trace endures over time
What is selective survival?
A type of statistical analysis which compares the means of 3 or more variables
what is an ANOVA?
A research design where the IV is measured before and after some treatment or manipulation
What is pretest-posttest?
The combined effect of two or more independent variables on the dependent variable
What is an interaction?
The characteristics of participants that cannot be manipulated by a researcher
What are Subject Variables?
A personal or private account NOT created for someone else to use
What is a Document?
the specific situations created by the IV manipulation for each group of the design
What are Levels?
arranging a series of experimental conditions or treatments in such a way as to minimize the influence of extraneous factors, such as practice or fatigue, on experimental results.
What is Counterbalancing?
When graphing a factorial analysis, we can expect to see this relationship between lines when there is no interaction?
What is parallel?
The requirement for identifying causality where the independent variable must be manipulated BEFORE measuring the dependent variable.
What is temporal priority?
Behavioral by-products which result in the accumulation of materials
This sequence effect refers to when participants perform worse during later treatment conditions because they're tired after a previous treatment condition
What is a fatigue effect?
A type of design that looks at changes over long periods of time (i.e. months or years)
What is a longitudinal study?
A mathematical way to refer to a factorial design with 2 levels of independent variable A, and 2 levels of independent variable B
What is a 2 X 2 factorial?
