7 Multi element designs

Question 1

RAPID alternation between two or more treatments/independent variables, while repeatedly measuring the dependent variable

No need to wait for a steady state responding before alternating to the next treatment condition

Similar to the logic of withdrawal design except this one has very brief phases

Answer 1

Multielement design

Question 2

Experimental control is demonstrated when the dependent variable is consistently different in one condition relative to the others. I.e., there’s differentiation in the data paths. They’re not all tangled together

Answer 2

Multi element design

Question 3

Can be good for comparing

-two or more treatments or assessment conditions Such as with a functional analysis

Answer 3

Advantages of a multi element design

Question 4

Subject to multiple treatment Interference

May require considerable attention toward proper counterbalancing

Not good for behavior that doesn’t reverse, has a long latency to change,

Not good for individuals that have difficulty forming discriminations between conditions

However, issues with the discriminability of different conditions might be mitigated by taking steps to make them more discriminable such as:
Use salient stimuli,
Use additional SD’s
Use fewer conditions or use instructions

Answer 4

Limitations of a multielement design

Question 5

ASR 1

Which of the following is true of multi element designs?

A. They require a long baseline and reversal faces

B. They require stability before moving onto the next phase

C. . They might not be good for behaviors that don’t quickly reverse

Answer 5

C

Question 6

ASR 2

Interpretation of a multi element design is helped if

There is differentiation between data paths

There is no differentiation between data paths

Answer 6

A

Question 7

Can minimize sequence effects if conditions are counterbalanced

Answer 7

One advantage of multi element design

Question 8

Maybe useful for highly variable behavior as long as the data paths show differentiation

Answer 8

One advantage of multi element design

Question 9

Can be more efficient than other designs in terms of number of sessions, as long reversal or baseline phases are NOT required

Answer 9

One advantage of multi element design
