Inhibitory control and working memory are linked to complex verb inflections in preschoolers, but not simple ones. This finding sheds light on language development and cognitive skills in young children.
Area of Science:
- Developmental Psychology
- Linguistics
- Cognitive Neuroscience
Background:
- Understanding the cognitive underpinnings of language acquisition is crucial.
- Verbal inflectional morphology, the system of word endings, is a complex linguistic feature.
- Inhibitory control and working memory are key executive functions that may support language development.
Purpose of the Study:
- To investigate the relationship between inhibitory control skills and Italian verbal inflectional morphology.
- To determine if these associations persist after accounting for receptive vocabulary and verbal working memory.
Main Methods:
- Assessed Italian preschoolers (aged 4-6) on inhibitory control (response inhibition, interference suppression) and verb inflection tasks.
- Employed hierarchical multiple regression analyses to examine associations.
Main Results:
- Working memory and interference suppression scores were significantly associated with complex verb inflections.
- No significant association was found between these cognitive skills and simple verb inflections.
Conclusions:
- Executive functions, specifically working memory and interference suppression, play a role in acquiring complex inflectional morphology.
- Simple inflectional morphology acquisition may rely on different cognitive mechanisms.

Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
