Abstract

This study examined if two-year-olds with ASD can update mental representations on the basis of verbal input. In an eye-tracking study, toddlers with ASD and typically-developing nonverbal age-matched controls were exposed to visual or verbal information about a change in a recently encoded scene, followed by an outcome that was either congruent or incongruent with that information. Findings revealed that both groups looked longer at incongruent outcomes, regardless of information modality, and despite the fact that toddlers with ASD had significantly lower measured verbal abilities than TD toddlers. This demonstrates that, although there is heterogeneity on the individual level, young toddlers with ASD can succeed in updating their mental representations on the basis of verbal input in a low-demand task.

1
The marginally significant difference between groups on fine motor scores can be attributed to a strong, positively skewed distribution of scores on this scale, in which four TD participants scored extremely high (> 50).
 
2
Due to concerns about fussiness-related data loss, we reduced the number of trials from Ganea et al. (2016), in line with their analyses demonstrating the same effects when only looking at the first trial in each block as when averaging across the whole block.
 
3
Adjusted df in accordance with a significant Levene’s test.
