Contrasting Accounts of Early Speech Perception and Production

Area of Science:

• Psycholinguistics
• Behavioral Psychology
• Developmental Psychology

Background:

• Historically, behavioral accounts of language acquisition have been overlooked.
• Current trends favor experience-dependent and usage-based language theories, often relying on inferred cognitive mechanisms.
• These theories emphasize the importance of context and experience in language learning.

Purpose of the Study:

• To critique usage-based theories of language acquisition from a cognitive linguistic perspective.
• To present and contrast a behavior-analytic theory of speech perception and production with cognitive theories.
• To highlight the role of automatic reinforcement in vocal development.

Main Methods:

• Critical analysis of usage-based language acquisition theories.
• Presentation of a behavior-analytic framework for speech perception and production.
• Comparative analysis of human infant and songbird vocal development.

Main Results:

• Usage-based theories present logical and methodological challenges.
• Cognitive theories of language acquisition often neglect the role of automatic reinforcement.
• Automatic reinforcement is proposed as a crucial factor in explaining vocal development.

Conclusions:

• A behavior-analytic approach, incorporating automatic reinforcement, offers a more parsimonious account of vocal development.
• This framework provides a missing link in understanding early language acquisition in human infants.
• Comparisons with songbird vocal learning support the proposed behavior-analytic model.
