What are the components of a line graph?
6
- X and Y axis lines
- labels for axis
- numbers on axis
- data points and lines connecting them
- phase line
- phase labels
What are the different variables and describe the functional relationship
- independent variable: treatment applied to the client
- dependent: target behaviour measre
- confounding (extraneous): another factor that may affect behaviour and is not controlled for
functional reationship: treatment causes a change
1. IV-DV: changing IV causes change in DV
2. replication: consistent pattern of results
Explain A-B design
list pro and cons
- has one baseline and treatment phase
- baseline: collect atleast 3 data points and make sure it doesn’t show a trend
pros: satisfactory for self-managment
cons: not a true research design as it lacks replication
A-B-A-B (reversal design)
- two baseline and treatment phase
- examines same behaviour for same client in same setting
- can include more than on kind of treatment
pros: can establish cause and effect
cons: may be unethical, behaviour may not revert back in second baseline
Mutliple baseline designs
3 of them; list pros and cons
- baselines may vary in length before treatment
- intervention phase is staggered across
1. multiple baseline across subjects: apply treatment to several different people
2. multiple baseline across behaviours: apply treatment to serveral different behaviours
3. across setting: applied treatment in different settings
pros: has no reversal, can see if behaviour occurs only when B phase starts
cons: treatments may spill over/spread across
Alternating-treatments (multielement) design
define fractionation and list pros and cons
- baseline and treatment (or two treatment) phases are applied in rapid succession
- fractionation: consistent vertical separation b/w treatment curves
pros: extraneous variables will have less effect, ecaluates effects of different treatments
cons: treatments may interacti with each other
Changing-criterion design
list pros and cons
- criterion for successful treament progressively changes
- uses A-B design
pros: good for behvaiours that can be approximated gradually
con: not good for behaviours that cant change gradually
