dc.description.abstract | We replicated and extended previous findings on utilizing lag schedules of reinforcement
to increase manding and decrease challenging behavior. We used FCT with a lag schedule to
teach the participant to request his toys with the mand "toys please" or "break please". We did
this using four modalities, including vocal, sign, picture, and button. Results suggest a functional
relation between the participant's frequency and variability of mands and the FCTlLag
intervention. There was also a functional relation determined between the FCT/Lap intervention
and the participant's CB. CB remained low and stable and eventually remaine d atzero.
Our study is a direct.replication of Willard and colleagues (under review) and shows
similar evidence in stable and high variable mands and low CB. However, Willard's participant
had a different diagnosis as the current study's participant and showed different challenging
behaviors. Similarly to Willard's, the current participant met the minimum response requirement
to access reinforcement without ever emitting unnecessary mands, which is also different from
Pokorski and colleagues (2020). The current participant would utilize a mand, almost always
button first, then wait to see if he received reinforcement. If not, he would move onto a different
mand. He never performed mands at the same time | en_US |
