Generalization and Discrimination of Positively Reinforced Explicit Mands in Young Children with Autism Spectrum Disorder.

Three preschoolers with autism learned to ask for things they wanted using words.

Each child got mand training for one specific request.

The team then tested if the child could tell when to use the new word and when not to.

All three kids learned their target request.

Two kids used the word only when it would get them the item.

One child asked for the item even when it would not work, showing overgeneralization.

Morris et al. (1982) showed that a 3-second pause helps kids with autism tell right from wrong answers. Chezan et al. (2024) did not use a pause, and one child still mixed up when to ask. You might add a brief wait time after you show the item to sharpen the child's choice.

Davison et al. (1995) also worked with three preschoolers with autism and saw gains spread to new toys and rooms. Chezan et al. (2024) found the same spread, but only for two of the three kids. The third child needed extra checks to stop the new word from popping up everywhere.

Leezenbaum et al. (2019) found that young children with autism struggle to wait for rewards. Chezan et al. (2024) turned that weakness into a strength by teaching the kids to ask right away and get the reward only when the rule allowed it.

After you teach a new mand, run quick probes with new items that do and do not match the rule. If the child asks for the wrong thing, add a brief pause or extra examples to fix the mix-up early. This small step saves hours of later retraining.
