Toy talk: simple strategies to create richer grammatical input

Area of Science:

• Linguistics
• Developmental Psychology
• Speech-Language Pathology

Background:

• Adult language input plays a crucial role in language acquisition and development.
• Toy talk strategies are increasingly recognized for their potential to enhance language modeling.
• Previous research has explored various methods for improving grammatical complexity in adult speech.

Purpose of the Study:

• To assess the feasibility of brief toy talk instruction in modifying adult grammatical language.
• To determine if toy talk strategies influence the use of 3rd person lexical noun phrase (NP) subjects.
• To examine changes in input informativeness for tense marking in adult speech.

Main Methods:

• Eighteen college students received brief instruction on toy talk strategies.
• The frequency of 3rd person subjects and lexical NP subjects was analyzed pre- and post-instruction.
• Input informativeness for tense was measured by the proportion of verb forms marked for tense.

Main Results:

• Statistically significant increases were observed in the use of 3rd person subjects (Cohen's d = 1.20).
• A significant rise in lexical NP subjects was noted (Cohen's d = 2.08).
• Input informativeness for tense showed a substantial increase (Cohen's d = 0.89).

Conclusions:

• Young adults can effectively learn and implement toy talk strategies with minimal instruction.
• Toy talk positively impacts the grammatical richness of adult language input, particularly tense/agreement marking.
• Findings support the integration of toy talk into language modeling practices and warrant further efficacy studies.
