Visual working memory in deaf children with diverse communication modes: improvement by differential outcomes.

López-Crespo et al. (2012) tested visual working memory in deaf children. They compared kids who use only spoken language, only sign language, or both.

Each child played a memory game on a computer. When they got a match right, they saw a picture reward right away. This is called the differential outcomes procedure.

Hearing children did the same game for comparison.

All deaf groups remembered more pictures when the reward picture followed the match. Hearing kids also improved with the reward pictures.

Children who used only speech or only sign still scored lower than kids who used both languages or than hearing peers. Yet the reward boost helped every group equally.

Blowers et al. (2021) used a cousin tactic with autistic kids. They taught the kids to watch both the model and the consequence. Both studies show that tuning the consequence sharpens attention.

Edmier et al. (2023) moved from memory games to full ABA therapy. They added ASL and Deaf-culture touches for a preschooler with autism. Their case mirrors our target: start with a basic behavioral tool, then wrap it in the child’s real language world.

Duarte et al. (2011) looked at Down syndrome, not deafness. They saw that adding a spatial move—sliding tokens to spots—lifted verbal memory. Like Ginesa’s picture rewards, an extra visual hook made the brain hold on to more.

If you work with deaf or hard-of-hearing learners, pair correct responses with a quick visual treat: a photo, sticker, or brief video. It costs nothing and lifts memory scores for every communication mode. Try it next session during matching, sight-word, or imitation drills.
