Multiple independent variable MULT I or parametric design

1
Multiple independent variable(MULT I) or
parametric design

• May be no true ______________
• Each phase consists of a different
  ___________________ ____________
• Exposure to each level may be in an________,
  __________, ________, or____________ order
• Functional relationship is demonstrated when
  behavior changes with__________
  ________________________________.
• Conditions may be ______________ for improved
  experimental control
• Each condition should be long enough to establish
  ______ at the new level of the IV.

2
See change in level of data path with each change
in value of the ___.
_______ builds confidence in effect
3

• Changing Criterion Design
• Like an AB design, with the B phase divided into
  _____________ (at least 3-4)
• Each treatment phase is associated with a _______
  _______________ for the target behavior
• Experimental control is demonstrated when
  behavior ________________________
  ___________________ (i.e., effects of IV is
  replicated)
• There may be a ______________________ for
  improved experimental control
• Each treatment phase should be long enough to
  establish __________ at the new criterion

Changing Criterion Design (cont)
5
Demonstrating a Functional Relationship in CCD
Lots of variability makes it harder to
_____________ _________ of criterion
Effect of criterion clearer when data are ______
to criterion level
6

• When Are Changing-Criterion Designs Used?
• When you plan to change behavior ___________
• When you dont want a long _____________
• When a ____________ design isnt appropriate
• When the study involves only 1 behavior, 1
  participant, and 1 setting
• When a ______________ can be established for
  behavior change
• Examples reducing caffeine or nicotine intake
  increasing childrens chore behaviors, homework
  completion, increasing exercise
