Graff and Karsten (2012) found that BCBAs reported conducting full scale preference assessments:
less than once a month
Zhou et al (2001) looked at correlation of PS preference assessment and found _____ correlation of rank-order preference over a 12-20 month period.
low
Individuals with ASD seem to have _______ stable preferences than individuals without ASD
more
Food preferences seem to be ______ stable than preferences for leisure items
more
DeLeon et al (2001) compared the results of a lengthy one-time PS assessment (top ranked item) and daily brief MSWO assessments (top ranked item) and found that the item chosen in the ________ assessment was generally a more effective reinforcer
daily
Research conducted by Zhou et al (2001) has suggested greater stability in stimuli ranked in what part of the preference hierarchy?
top
Which of the following has been suggested as a determining factor in whether or not frequent preference assessments help increase accuracy?
if preferences vary
According to a survey by Graff and Karsten (2012), how often did most BCBAs say they conducted mini preference assessments?
several times a day
The effectiveness of a reinforcer refers to both its _________ capacity to support responses that produce it and its utility in producing ________ behavior change
momentary, long-term
The studies by Hanley et al on changing preferences found that enhancing an activity with ________ _________ reinforcement can temporarily shift choices towards that activity
supplemental contingent
The studies by Hanley et al on changing preferences found that noncontingent pairing of an activity with established preferred stimuli can ________ shift choices towards that activity
temporarily
The studies by Hanley et al on changing preferences found that effects of pairing procedures appear to be ________
transient
List 4 determinants of stimulus value:
delay, rate, quality, magnitude
Generally, delays to reinforcement can ________ the effectiveness of behavioral arrangements and result in ________ in the value of a reinforcer
weaken, decreases
When delays occur, primary, directly consumable reinforcers are discounted ______ _______ than conditioned reinforcers
more steeply
Leon et al assessed delayed food, delayed tokens, and immediate tokens w/delayed exchange and found that:
- delayed _______ produced greatest persistence
- delayed _______ produced most rapid decreases in responding
- immediate token delivery with a delayed exchange opportunity equaled or ______ effects of delayed food
o
food, tokens, exceeded
In the Leon et al study of delayed reinforcement, which item produced the greatest persistence?
delayed food
In the Leon et al study of delayed reinforcement, which item produced the most rapid decreases in responding?
delayed tokens
Organisms will distribute behavior among concurrently available alternatives in the same proportion that reinforcers are distributed among those alternatives.
Matching law
Quality of reinforcement is conceptualized in terms of:
level of preference (higher preference = better quality)
Magnitude of reinforcement can vary according to:
quantity, intensity or duration
Research examining the effects of reinforcer quality has generally suggested that:
better quality reinforcers may function as more potent reinforcers
Research examining the effects of delay to reinforcement has generally suggested that:
delays can decrease the value of a reinforcer
When thinning schedules of reinforcement, consider the ________ of reinforcement
magnitude
