Visual Motion Prediction and Verbal False Memory Performance in Autistic Children.
Furtuna G Tewolde, Dorothy V M Bishop, Catherine Manning
PMID 29271070WHAT IT FOUND
Autistic children predicted hidden moving events as well as typically developing children.
Their verbal false memory performance did not clearly differ. This does not support a general prediction impairment in autism.
Key findings
01Children with autism and typically developing children did not differ in how consistently they predicted when a hidden car or filling grid would finish.
02Both groups falsely recognized strongly related words that had not been read, and the groups did not differ clearly in rejecting them.
03Children who were better at telling real words from false words were also more consistent in the visual prediction tasks, the opposite of the expected link.

What it does not show
The visual tasks were simple, predictable and supported by a track or grid, so they do not show whether autistic children predict complex, weakly linked or everyday events. The sample was limited to children with IQ above 70 and normal or corrected vision, so the results may not apply to autistic children with lower intellectual ability or visual impairment. The autistic group had lower verbal IQ than the comparison group, which could influence verbal false memory comparisons. The false memory group difference was unclear, and the study may have been too small to settle it if the real difference is smaller than the one it was planned to detect. The link between visual prediction and false memory was exploratory and opposite to the expected direction.

The easy way to misread this
Do not conclude that autistic children have no prediction difficulties. The tasks used simple, predictable motion with visual supports, so they do not test complex, weakly linked or social prediction.
