Visuospatial support for verbal short-term memory in individuals with Down syndrome.

Duarte et al. (2011) tested verbal short-term memory in kids with Down syndrome. They compared three setups: words only, pictures only, and words plus moving tokens to spaces on a board.

Each child tried all three setups in one session. The task was to repeat a short list of words in order. The spatial version let kids slide a token to a square each time they heard a word.

Kids with Down syndrome remembered the word list best when they could move the tokens. Their scores jumped only in the spatial-plus-verbal version.

Pure visual cues or pure verbal lists gave no boost. The spatial action was the key ingredient.

Tonnsen et al. (2016) saw the same pattern in autistic readers. Adding visual imagery to text lifted both brain activity and comprehension, a close cousin to Perez’s spatial boost.

Harper-Hill et al. (2014) looks like a clash. They found written visual primes did not speed spoken-word recognition for kids with ASD. The gap is real but sensible: Perez used active hand movements tied to word order, while Keely used passive printed primes. Action beats static cues for these populations.

Matson et al. (1994) extends the idea into daily life. Parents used simple picture cues at home and their developmentally-delayed children talked more. Spatial support can travel beyond the lab table.

If you teach sequences—letters, numbers, or daily steps—to learners with Down syndrome, give them something to move. Place cards in a row, slide counters, or let them point to spots on a grid. One small motor action can lock the verbal chain in place.
