Effects of reinforcement for alternative behavior during punishment of self-injury.

Reid et al. (1999) worked with four adults with intellectual disability who hit or bit themselves.

The team gave brief reprimands or light manual restraint each time self-injury happened.

At the same moment they delivered leisure items and praised any touching or manipulation of those items.

Sessions alternated between punishment alone and punishment plus this simple reinforcement.

Self-injury dropped further when reinforcement for toy play ran alongside the mild punishment.

The extra reinforcement did not merely accompany the effect; it clearly boosted suppression.

All four participants showed the same pattern, making the result easy to see.

Lord et al. (1997) tried intermittent punishment alone and only two of four clients kept gains.

Adding reinforcement, as H et al. did, appears to solve that weakness.

Rooker et al. (2022) later swapped leisure items for dense food rewards while clients pressed a switch; again, self-injury fell, showing the boost holds across reinforcer types and even when behavior is automatically reinforced.

Johnston et al. (2017) and Capio et al. (2013) warn that rich reinforcement can later rebound when you remove it; their lab work reminds clinicians to thin carefully after the initial suppression.

If you must use punishment for dangerous self-injury, pair it immediately with an easy, reinforced alternative response such as touching a toy, switch, or book. The combination gives stronger suppression than punishment alone and works for both socially and automatically maintained behavior. Plan to thin the extra reinforcement once suppression is stable so you avoid resurgence later.
