Neural dynamics of executive function in cognitively able kindergarteners with autism spectrum disorders as predictors of concurrent academic achievement.

PMID 31793795

WHAT IT FOUND

In cognitively able kindergarteners with autism, some brain responses to errors during a button game were linked to better reading and math scores at school entry.

The study did not test whether improving these responses helps achievement.

Key findings

01During a Go/No-go game, error trials produced a larger frontal ERN, a larger posterior Pe, and greater frontal theta than correct trials.

02After controlling for task accuracy and nonverbal IQ, greater error-related frontal theta predicted better reading comprehension and math facts fluency.

03Greater posterior Pe also predicted math facts fluency, while ERN did not predict any academic domain.

What it does not show

The sample was small and included only cognitively able children with autism without notable structural language delays, so results do not generalize to children with significant cognitive or language delays. There was no comparison group of typically developing children, so the neural measures cannot be interpreted as specific to autism. Academic and brain measures were assessed at the same time, so they do not show that error-monitoring activity predicts later achievement. Many children could not meet the starting point for math facts fluency, so raw scores and a special regression approach were needed. Classroom placements varied and were not randomly assigned, so school setting may be linked to child characteristics.

Declared interests

The paper is listed as NIH extramural research support. The supplied text does not report author conflicts of interest or whether the funder designed, collected, analyzed, or wrote the study.

The easy way to misread this

Do not conclude that brain responses to errors can be used to predict school achievement for all children with autism or that training error monitoring improves achievement. This was a small cross-sectional association in cognitively able children without notable structural language delays, and no intervention was tested.
