PSYB45Chapter 3
Graph – visual representation of the occurrence of a behavior over time
6 components for a graph to be complete:
1)y- and x-axis
2)labels for the axis
3)numbers of the axis
4)data points
5)phase lines – indicates a change in treatment
6)phase lables
a.Baseline – label given to the no-treatment phase
Research design
Determines whether treatment (IV) influenced target behavior (DV)
to rule out possibility of confounding variables affecting DV
Functional relationship – behaviour changes as a function of the procedure
Established if
oDV changes when IV is manipulated, while all other variables are held constant
oProcess is repeated one or more times and DV changes each time
A-B Design – 2 phases: A=baseline, B=treatment
compares ______________ and ________________ to determine whether the behavior changed in
the expected way after treatment
does not demonstrate a functional relationship (treatment is not implemented a 2nd time)
not a true research design (does not rule out possible confounding variables)
Is rarely used in behavior modification research (most often is used in applied, nonresearch
situations in which people are more interested in demonstrating that behavior change has
occurred than in proving that the behavior modification procedure caused the change)
A-B-A-B Reversal Design – baseline and treatment are implemented twice
Multiple-Baseline Design
used when a) you are interested in the same target behavior exhibited by multiple subjects, b)
you have targeted more than one behavior of the same subject, c) you are measuring a subjects
behavior across 2 or more settings
treatment is staggered over time
1)Multiple-baseline-across-subjects design
a.there is a baseline and a treatment phase for the same target behaviour of 2 or
more different subjects
2)Multiple-baseline-across-behavior design
a.there is a baseline and treatment phase for 2 or more different behaviors of the
same subject
3)Multiple-baseline-across-settings design
a.- There is a baseline and treatment phase for 2 or more settings in which the
same behavior of the subject is measured

OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!

Balancing social life With academics can be difficult, that is why I'm so glad that OneClass is out there where I can find the top notes for all of my classes. Now I can be the all-star student I want to be.
