Cross-situational statistically based word learning intervention for late-talking toddlers

Area of Science:

• Developmental Psychology
• Linguistics
• Speech-Language Pathology

Background:

• Late-talking toddlers often experience vocabulary delays.
• Cross-situational statistical learning is a mechanism for word acquisition.
• Interventions can leverage statistical learning principles for language development.

Purpose of the Study:

• To evaluate an input-based word learning intervention for late-talking toddlers.
• The intervention was designed using principles of cross-situational statistical learning.
• To assess the efficacy of this intervention on vocabulary acquisition.

Main Methods:

• Four late-talking toddlers received 7-10 weeks of bi-weekly intervention.
• The intervention focused on input and cross-situational statistical learning.
• Vocabulary gains were measured using parent reports and language samples.

Main Results:

• Children learned significantly more target words than control words.
• A large treatment effect size was observed.
• Vocabulary percentile scores increased, showing faster-than-literature rates of word learning.

Conclusions:

• Cross-situational statistical learning interventions show promise for improving toddler vocabulary.
• This approach may offer a viable treatment for late-talking toddlers.
• Further research is needed to explore limitations and optimize intervention strategies.
