Lecture 2 - Finding Research and Research Designs Flashcards
(27 cards)
What is the dependent variable?
the targer behaviour that you are interested in changing.
What does a DV need to have?
social significance
what are some examples of dependent variables?
aggression, social interactions and correct reponses.
What is the independent variable?
the variable that you manipulate in your study.
what is the IV related to?
the research questions being asked
whar are some examples of IV’s?
interventions, teaching strategies, reinforcement contingenices.
what does a experiemental research design do?
demonstrates a functional relation between the DV and IV.
what is a functional relation?
when a specified change in the DV can be reliably produced by a specific manipulation of the IV.
How is an experimental design different from a quasi-experimental design?
In the way particpants are assigned - in quasi p’s are not assigned randomly.
What does a correlational research design do?
predicts relations between the DV and the IV but no not verify the prediction.
Qualatative research may use…
correlations.
In which kind of design do all p’s have the intervention at some point - group or single subjects?
Single subject design
which design usually uses statistical analysis - group or single subject?
group design
does a single subject design always mean there is only one person involved?
No
How are group and single subject designs similar?
both can be replicated and both want to show a functional relation between dv and iv.
In which design (group or sinlge subject) is there comparison BETWEEN subjects?
Group
In which design (group or sinlge subject) is there comparison WITHIN subjects?
Single subject
What happens in a group design?
P’s are assigned to 1 of at least 2 groups and iv is assigned to one.
What are group designs not concerned with?
Individual performance
What is internal validity?
How well the experimenter controlled for extraneous variables and alternative explanations.
What are some setting confounds?
Uncontrolled variables in settings and uncontrolled access to reinforcers
What is oberver drift?
unintended change in the way an observer uses a meausrement system over the course of an investigation
What are oberserver bias, observer drift, reactivity and practice effects all types of?
Measurement confounds
What are some IV confounds?
Placebo effects, treatment drift, poor operational definitons.
