Children with ASD Show Impaired Item-Space Recollection, But Preserved Item-Color Recollection.
Color memory stays strong in autism, but spatial memory needs help.
01Research in Context
What this study did
The team asked kids to look at pictures. Each picture had a color and a spot on a grid.
Later the kids tried to remember which color went with which picture and where each picture sat.
All kids were 8-11 years old. Half had autism, half were typically developing.
What they found
Children with autism matched colors to pictures just as well as peers.
They forgot the grid spots far more often than peers. Spatial links slipped away while color links stayed.
How this fits with other research
Järvinen-Pasley et al. (2008) once said color memory is weak in autism. The new study shows the opposite. The gap is age: the older paper mixed ages; this one kept the tight 8-11 window.
Schlink et al. (2022) found visual working memory for color grows normally. That supports the new finding that color binding can hold steady.
Desaunay et al. (2023) used brain waves and saw memories stored fine but harder to pull out. Their EEG result backs the idea that the color data are in there; we just need to help kids retrieve them.
Why it matters
When you teach a new sight-word, pair it with a bright color cue instead of a place on the table. If you need kids to remember where materials go, add extra prompts or visual anchors because the spatial part fades first.

03Original abstract
Although individuals with autism spectrum disorder (ASD) have been often shown to display similar memory performance on semantic memory tasks compared to typically developing (TD) children, there is ongoing debate about whether and how their ability to remember specific past events (i.e., episodic memory) is impaired. We assessed a sample of 62 children with ASD and 72 TD children, ranging in age between 8 and 12 years on 2 memory tasks. Participants encoded a series of images and their association with either where they appeared on the screen (item-space association task) or with the color of an image's border (item-color association task). Children with ASD showed worse memory in the item-space association task compared to their TD peers, but comparable memory for the item-color association task. These differences persisted when age, intellectual quotient, and general item recognition memory were accounted for statistically. We interpret these results in light of evidence for specific deficits along the dorsal stream affecting processing of spatiotemporal information in ASD.

Here, we compared children with autism spectrum disorder (ASD) and typically developing (TD) children on tasks examining episodic memory. Children with ASD recalled more poorly previously seen items and their associated space-related details, but they performed comparably to TD children on color details. We discuss the possible mechanisms that contribute to worse spatial processing/recall in ASD.
