L9 - Critical thinking Flashcards
What is a hypotheses?
Defines what you want to test
What measurement approach would you use for behaviour?
Observation
What measurement approach would you use for attitudes/ ideas?
Survey
What measurement approach would you use for determining cause?
Experiment
What is a causal hypothesis?
“If I change X, Y will change”
What is a predictive hypothesis?
“These groups respond differently”
When do you use non-equivalent control groups?
Has both experimental and control groups
Subjects aren’t randomly assigned
When is a mix factorial design with One non-manipulated variable appropriate?
More than one IV, one of which isn’t randomly assigned
When would you use a design without a control group?
*Interrupted Time Series Design: Compare same group over time before and after manipulation
*Repeated-Treatment Design: Baseline, treatment, withdrawal, treatment again
What is a cross-sectional study?
Different age groups at the same time –> risk of cohort effects
What is a longitudinal study?
Study of the same group over a long period of time
What is a cross-sequential design?
Multiple cohorts at multiple to separate effects
What is the purpose of a meta-analysis?
Combine results from multiple studies –> leads to a larger view of the topic, examining effect size vs significance
Why is a single-subject designs?
Practical when multi-subject designs aren’t possible?
What’s the advantages of single-subject design?
*Avoids distortion from group
means.
*Clinically significant effects.
*Practical and ethical flexibility.
What is an AB design?
Baseline followed by treatment
What is an ABA Design?
Baseline, treatment, removal of treatment
Alternating treatments design
compare multiple treatments
Multiple baseline design
Change in behaviour corresponds to trearment onset
Changing criterion design
Successive criteria for reinforcement to shape behaviour
Factorial single-subject design
Multiple treatments tested for effectiveness
