Flashcards in Preference Assessment Deck (27):
Does preference assessment tell us what reinforcer to use?
NO! A preference assessment doesn't tell us whether something functions as reinforcer, just that client prefers over other choices
The stimuli we use in interventions should have a high probability...
of functioning as a reinforcer
What are the three most basic approach to identifying potential reinforcers?
Asking the client; observing behaviour; conducting assessments
When asking, what should be used instead of open-ended questions?
Give a limitation to asking client their preferred reinforcer
May not be able to speak; may not be able to remember what they'd like; may lead to unreasonable demands
What previous results can we use to identify potential reinforcers?
Give three types of structured preference assessments
1) Single presentation 2) Paired/forced choice 3) Multiple presentation preference assessment
Briefly outline the single presentation preference assessment procedure
Choose several potential reinforcers, display each item individually for limited time, note whether the person approaches the item, repeat process to gather enough data
If the client doesn't approach items during single presentation preference assessments you should...
prompt the person to sample the item
You should only use sampling...
on the first presentation of the item
If a selected item has no value as a reinforcer, you could...
replace the item with another item
Once items in a single presentation preference assessment have been presented several times you can calculate...
the percentage of times client approached and duration of each interaction
In single presentation preference assessment you should limit...
access to the item
Briefly outline the paired choice preference assessment procedure
Choose several items; display two items simultaneously for a limited time; record the item chosen; randomly present items until all have been presented with one another
What is another term for paired choice preference assessment?
Forced choice preference assessment
If a client attempts to access more than one item you should...
block their attempts
If during paired choice preference assessment no item is selected...
use sampling then present items again
Why is paired choice preference assessment better than single presentation preference assessment?
Paired choice less likely to overestimate reinforcing effects of stimuli
Briefly outline multiple presentation stimulus preference assessment procedure
Choose several items, present an array of items at once, record which items are chosen
What are the two types of multiple presentation stimulus preference assessment?
1) With replacement (MS)
2) Without replacement (MSWO)
Describe MS with replacement
Once an item has been selected it is put back into the selection
Once an item has been selected it is removed from the selection and therefore no longer available
Why is using MSWO usually better than using MS?
Multiple presentation stimulus preference produces a larger number of potential reinforcers
Which, of all preference assessments, does research suggest is the most efficient?
Multiple presentation stimulus preference without replacement (MSWO)
When might MS be better than MSWO?
When trying to identify one or two potent reinforcers
What should follow preference assessments? Why?
Reinforcer assessments. Because the preference doesn't tell us whether an item is reinforcing
