Behavioral momentum in the treatment of escape-motivated stereotypy.

Researchers worked with one adult who had severe intellectual disability.

The person showed repeated body movements whenever staff gave hard tasks.

The team first checked that the movements happened to escape work.

Then they tried a momentum trick: three quick easy requests right before the hard one.

The short warm-up of easy tasks cut the stereotypy almost to zero.

Compliance jumped right after the high-probability sequence.

The effect showed up fast and stayed while the sequence was used.

Giallo et al. (2006) copied the same trick at the dinner table. They used three easy bites before a new food and saw better eating and less crying.

Carr et al. (2003) pushed the idea further. They mixed easy math problems with hard ones and wiped out escape aggression without any extinction.

Iwata et al. (1990) looks like a clash at first glance. That team simply blocked escape and the self-injury stopped. But the behaviors differed: the 1990 paper used extinction for self-injury, while C et al. used momentum for stereotypy. Different topographies, different tools, both valid.

You can soften hard demands in any setting by sliding in three quick wins first. No need to block escape or ride out a burst. Try it during hygiene, table work, or transitions. It takes seconds and gives you compliance momentum without extra toys or tokens.
