9] Application of Behaviour Psychology [2] Flashcards
What are randomised control trials (RCTs)
They’re used to investigate intervention efficiency
What is a single subject design (SSD)
How does single subject designs (SSD) work
It relies on the comparison of treatment effects on a single subject or group of single subjects, instead of comparing groups
What does SSD measure
Behavioural change, degree of change or when preforming behavioural modifications
SSDS
SSDS
Examples of SSDs
1] Reversal designs
2] Alternating treatment designs
3] Multiple baseline designs
4] Multiple probe design
5] Changing criterion designs

SSDs: What is a reversal design
It is the repeated measures of behaviour in a given setting
Reversal designs: What are the consecutive phases
1] Initial baseline (A)
2] Intervention (B)
3] Return baseline (A)
What does A-B-A design determine
The efficacy of the IV (intervention) by looking if baseline/treatment phases remain the same pre and post-test
What is A-B-A-
Known as the withdrawal design, it investigates the interventions (IV) efficiency on behaviour by comparing the baseline to its original phase
What is the A-B-A-B reversal
It the same concept as A-B-A, but has a repeated intervention phase
Why is A-B-A-B preferred over A-B-A
1] Stronger demonstration
2] Good for SSD demonstrating a relationship between intentions and behaviour
3] Ethical, return subject to intervention
Cons of A-B-A-B design
1] Maturation
2] Timing/amount of training
3] Threatened validity
What are multiple base line designs
Uses varying time schedules, ruling the treatment is influencing a behavioural change
MBD are used when…
