About

The purpose of the study is to investigate how word characteristics (e.g., phonotactic probability) and orthography affect vocabulary by children with low oral language levels. The investigators will use a 2 x 2 within-subjects factorial design where every participant receives the treatment. This 12-week study aims to improve vocabulary learning efficiency for children with low oral language levels. The study's findings will uniquely contribute to the field in that this is the first research study using real words instead of nonwords while combining word learning research with vocabulary learning.

Full description

The investigators are proposing a vocabulary intervention that analyzes word sounds and sound segments. This analysis offers valuable insights into how children at risk for specific learning disabilities, such as dyslexia or speech and language impairments, learn words differently from typically developing children.
