BEHV 5612 - Cum Exam 2 Questions And Answers
What was the first formalized stimulus preference assessment? - Answer Single
Stimulus Preference Assessment
Describe a Single Stimulus Preference Assessment - Answer - provide single item to
child
- record behavioral responses to each item
- record duration of engagement with each item
- preferable for children who are unable to scan a field of two items
- preferable for children who engage in challenging behavior when preferred toys are
taken away
What is a flat distribution? - Answer Every item is chosen about the same amount. This
indicates the child may be making random choices or not attending.
What does the choice-based preference assessment require of the child? - Answer
Requires the child to travel to retrieve the item
Describe the Paired-Choice Preference Assessment - Answer - allows for a hierarchy of
child's preferences
- two items are placed at a time and child is asked to make a choice
- each possible pair of combinations is presented (time-consuming)
- not appropriate when engage in problem behavior when preferred items are taken
away
- appropriate for students who are able to select between high and low preferreds
- appropriate for students who can only scan a small field
,Changes in preference are dynamic and change because of... - Answer reinforcer
efficacy
Describe Multiple Stimulus Without Replacement Preference Assessment (MSWO) -
Answer - produces hierarchy of child's preferences
- array is placed in front of child, after child selects and plays with item, that item is
removed from array
- brief assessment time
- child must have ability to scan larger array
- not appropriate for children who engage in problem behavior when preferred items are
removed
What are some limitations of MSWO? - Answer - positional bias due to dominant hand
- the child "saving the best for last"
Describe Free Operant Preference Assessment (FO) - Answer - appropriate for all
children
- present array and allow access to all items
- never take away items
- measure duration spent with each item
What are some limitations of FO? - Answer - may not result in a good hierarchy
- may only play with one item
- may not yield relative value of other reinforcers
- can be lengthy
What is response restriction? - Answer Taking the most preferred item out of an array
Describe Single Operant Preference Assessment - Answer - the dependent variable
, serves as the response rate or frequency
- typically a fixed ratio schedule of reinforcement
- compare to baseline rates
- single stimulus available at any given time for a single response
Describe Concurrent Operant Preference Assessment - Answer - option to complete
two versions of the same task
- each available reinforcer is a associated with a different response
What is a Progressive Ratio Schedule? - Answer how much work.a learner is willing to
do in order to earn a reinforcer (example: 1 task then reinforcer or 3 tasks then
reinforcer)
What are some reasons to be cautious of food reinforcers? - Answer - dental/health
concerns
- disrupt the rate of responding when included in an array of leisure items
- can lead to satiation and become less efficient
Interobserver reliability - Answer occurs if two or more observers score participants on
an assessment simultaneously
Testretest reliability - Answer occurs if participants were scored on assessment at two
separate time periods
Splithalf reliability - Answer occurs is scores on one half of the assessment were related
to scores on the other half
Content validity - Answer occurs if degree to which the assessment is fully
representative of what it intends to measure
