Effect of Word Characteristics and Orthography on Vocabulary Learning
Sponsor: Mariana Silva
Summary
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.

The purpose of the study is to investigate how word characteristics (e.g., phonotactic probability) and orthography effect vocabulary learning by children with low oral language levels. We will be using a 2 x 2 within-subjects factorial design where every participant serves as their own control. This 12-week study aims to improve the Efficiency of vocabulary learning for children with low oral language levels. The four interventions that are all participants will be exposed to are the following: high pp words with orthography; high pp words without orthography; low pp words with orthography; low pp words without orthography.
