Psychological linguistics: implications for a theory of initial development and a method for research

Area of Science:

• Psychology
• Linguistics
• Developmental Psychology

Background:

• Based on Kantor's psychological linguistics, this study outlines a novel hypothesis for language acquisition.
• Existing research often focuses on specific linguistic aspects, but a comprehensive developmental model is needed.

Purpose of the Study:

• To propose a four-stage hypothesis of language development from infancy through early childhood.
• To describe a method for studying language interactions using video recordings.

Main Methods:

• Observational analysis of language development in four distinct stages.
• Utilizing TV tapes to record and analyze speaker and listener behavior, referents, and setting conditions.
• Detailed analysis of speaker behavior, including initiation frequency, utterance length, modality, content, and emotional reactions.

Main Results:

• Identified four stages of language development: early gestural communication and receptive speech (0-15 months), holophrastic speech (12-24 months), first-approximation referential interactions (24-30 months), and second-approximation speech with symbolizing behavior (approx. 52 months).
• Demonstrated that language development continues beyond these stages, influenced by social factors and leading to specialized speech forms.
• Established a systematic method for analyzing the multifaceted components of language interactions.

Conclusions:

• The proposed four-stage model provides a framework for understanding the progression of language acquisition.
• The described methodology offers a robust approach to studying the complexities of human communication.
• Further research can build upon this model to explore variations and influences on language development.
