How Executive Function Supports Early Language Learning: New Findings from a Dutch Preschool Study
Summary: New research finds that children’s executive function—the cognitive skills that support self-control, attention, and planning—is strongly linked to how they process and learn language. In a study of 120 Dutch preschoolers aged 4 to 5, researchers used sentence-comprehension tasks and eye-tracking to show that children with stronger executive control better interpreted challenging sentence structures such as the passive voice.
The study reveals that executive function helps children revise initial misinterpretations as they listen and learn, and that language development and executive function appear to reinforce one another as children grow. These results illuminate a dynamic relationship between cognitive control and syntax acquisition during early childhood.
Key findings
- Executive function predicts comprehension: Children with higher executive function were more accurate when interpreting passive sentences, which younger children often find difficult.
- Mutual reinforcement: Language skills and executive function likely form a positive feedback loop, where gains in one domain support development in the other over time.
- Processing and learning advantages: Strong executive function was related both to better online revision of misinterpretations and to longer-term improvements in understanding non‑canonical sentence structures, although longer-term effects were closely linked to overall language ability.
Led by Associate Professor Malathi Thothathiri from the George Washington University Department of Speech, Language and Hearing Sciences, together with colleagues from the Max Planck Institute, the research examined how executive function contributes to both the real-time processing of sentences and the acquisition of syntactic knowledge over time.
The participants were 120 Dutch preschoolers, ages 4 and 5. Each child completed a sequence of three sessions: a pre-test, an exposure session, and a post-test. During pre-test and post-test sessions researchers measured comprehension of passive sentences and administered three separate tasks designed to assess executive function. The exposure session focused on online processing: children listened to passive and other types of sentences while their eye movements were tracked to reveal moment-by-moment interpretation decisions.
Children were also assessed for short-term memory and receptive language ability so the researchers could account for these factors when evaluating the specific contribution of executive function. The data were analyzed using multiple regression techniques to evaluate relationships between executive function, online processing accuracy, and longer-term learning of non-canonical structures.
Results showed that executive function uniquely predicted a child’s ability to revise an initial, incorrect interpretation during online sentence processing, even after controlling for receptive language, prior knowledge of passive constructions, and short-term memory. In other words, children with stronger cognitive control were better able to detect and correct misinterpretations as a sentence unfolded. Executive function was also associated with greater improvement in passive comprehension over the study period, but this longer-term learning effect was intertwined with children’s broader receptive language skills.
These outcomes support a model in which executive function plays a direct role in the real-time revision process that underlies accurate sentence interpretation, and in which reciprocal interactions between executive skills and language ability contribute to lasting gains in syntax learning. In practical terms, strengthening executive function during early childhood may help children more effectively process complex sentence patterns, and richer language experiences may in turn bolster cognitive control.

Abstract
The Role of Executive Function in the Processing and Acquisition of Syntax
Language acquisition depends not only on language-specific mechanisms but also on broader cognitive capacities. The authors hypothesized that executive function (EF) supports language development by enabling children to revise misinterpretations during online processing, to encode linguistic input more accurately, and to learn non‑canonical sentence structures such as the passive over time.
One hundred and twenty Dutch preschoolers completed three testing sessions (pre-test, exposure, and post-test). Pre-test and post-test measured comprehension of passive sentences and three EF tasks; in the exposure session eye tracking recorded children’s moment-to-moment interpretations while they listened to passive and other sentences. Short-term memory and receptive language were also assessed. Multiple regression analyses evaluated relations among EF, online processing, and longer-term learning.
Findings show that EF predicted online revision accuracy when controlling for receptive language, prior passive knowledge, and short-term memory, supporting theories that link EF to the revision of misinterpretations. EF was also associated with longer-term learning, although this effect could not be fully separated from receptive language abilities. Overall, the results support a role for EF in language acquisition, particularly in revision during sentence processing, and suggest reciprocal interactions between EF and receptive language in supporting syntax development.
