intensive teaching and video problem

[Guest guest]

Hi everyone:

I'm new for this group and we just got VB consultant and stated in

home VB program. Before that I teached my son signs for manding in

natural enviroments. But it's hard to teach him imitation skills and

receptive language skills in the natural enviroment. Our consult

helped us set up intensive teaching seesion on the table and using my

son's favorite video as reinforcer.

Now our problem is: after I paused video, my son immediately signed

video for me and I didn't have chance to teach him new skills. Even I

caught some opportunity to do some trials, he just kept signing video

for me and didn't pay attention to my instructions at all. So the

video kindly distracted him from following my instructions, it worked

more likely as distraction to follow my command than reinforcer.

Before I also used some reinforcers to ask him work for some trial

such as some motor imitation and manding before giving him reinforcer.

But he became upset very soon and would threw the reinforcer on the

floor and didn't want to reach them for a long time. Only pacifer and

video are consistant reinforcers. But if he saw the two them he will

immediately mand them and I can't introduce any new trials.

So my question is: what's suggestions for reinforcers to be used

during intensive teaching? Before we use food, favorite toys as

reinforcers, but my son became very upset soon. Now we use video as

reinforcer but it seems distract him to follow my instructions.

Thanks a lot for any inputs.
