How known constructions influence the acquisition of other constructions: the german passive and future constructions

Area of Science:

• Linguistics
• Developmental Psychology
• Language Acquisition

Background:

• Prior linguistic knowledge can influence the learning of new grammatical constructions.
• Understanding facilitation and inhibition is key to modeling language acquisition.
• The German passive and future constructions offer a model for studying auxiliary verb influences.

Purpose of the Study:

• To investigate how prior acquisition of German auxiliary constructions (sein/werden) affects the learning of new passive and future constructions.
• To test predictions that supported constructions are acquired faster, and inhibited constructions slower.
• To analyze the role of emergentist principles in language learning, even for seemingly rapid acquisition.

Main Methods:

• Analysis of a dense longitudinal corpus of a German-speaking child's language development from ages 2;0 to 5;0.
• Tracking the acquisition timeline and usage patterns of German passive and future constructions.
• Identifying supporting or hindering relationships between previously acquired and newly acquired constructions.

Main Results:

• The child acquired the 'sein'-passive construction earlier than the 'werden'-passive.
• The 'sein'-passive was facilitated by prior 'sein' copula acquisition; the 'werden'-passive supported a 'werden' copula construction.
• The 'werden'-future construction was acquired very slowly due to interference from a semantically similar construction.

Conclusions:

• Prior acquisition significantly facilitates or inhibits the learning of related new constructions.
• Observed acquisition patterns align with emergentist theories, emphasizing gradual learning mechanisms.
• The study provides empirical evidence for the complex interplay between existing linguistic knowledge and new language acquisition.
