Children learn syntax item by item, with early learning speeding up later acquisition. Practice is key to mastering syntactic structures, though it can initially slow down the learning process.

Area of Science:

Psycholinguistics
Developmental Psychology
Computational Linguistics

Background:

Syntax acquisition is a complex developmental process.
Understanding the mechanisms driving early language learning is crucial.
Item-based learning and practice effects are proposed factors.

Purpose of the Study:

To present and test a model of syntax acquisition.
To investigate the roles of item-based learning, facilitation, and practice.
To analyze the developmental trajectory of syntactic structures in young children.

Main Methods:

Analysis of naturalistic speech production samples.
Longitudinal study of six Hebrew-acquiring children (ages 1;1 to 2;7).
Examination of verb entry rates and error patterns in syntactic structures.

Main Results:

Most syntactic structures showed accelerating learning rates, supporting the facilitation hypothesis.
An inverse correlation between verb frequency and errors indicated the role of practice.
Lack of acceleration in some structures was linked to reduced practice.

Conclusions:

Syntax acquisition is predominantly item-based, with early learning facilitating later stages.
Practice, while essential for mastery, can initially impede learning speed.
The model effectively explains variations in syntactic development based on learning mechanisms.
