The development of early phonological networks: An analysis of individual longitudinal vocabulary growth

Опубликована: Фев. 23, 2024

While much work has emphasized the role of environment in language learning, research equally reports consistent effects child’s knowledge, particular, words known to individual children, steering further lexical development. Much this is based on cross-sectional data, assuming that typically children at n months predict n+x months. Given acknowledged variability number different ages, a more conclusive analysis issue requires examination differences learned by across development, i.e., using longitudinal data. In current study, vocabulary data from learning Norwegian, we ask whether phonological connectivity word child already knows or predicts likelihood We compare three measures have been used literature to-date. The results suggest early grows predominantly rich-get-richer manner, where predicted words. However, is, lesser extent, also influenced linguistic environment. Our highlight promise better understand factors influence development and insights be gained analyzing same construct.

Abstract Phonological networks are representations of word forms and their phonological relationships with other words in a given language lexicon. A principle underlying the growth (or evolution) those is preferential attachment, or “rich-gets-richer” mechanisms, according to which many neighbors links) main beneficiaries future opportunities. Due limited number words, lexica constitute node-constrained where cannot keep increasing linear way; hence, attachment likely mitigated by certain factors. The present study investigated obsolescence effects (i.e., word’s finite timespan being active terms growth) an evolving network English as second language. It was found that neighborhoods constructed one large initial lexical spurt, followed sublinear spurts eventually lead very later during evolution. First-language-given neighborhood densities rarely reached even most advanced learners. An analysis strength between revealed tendency incorporate phonetically more distant at earlier acquisition stages. Overall, findings suggest effect favors younger words. Implications for second-language lexicon include leveraged learning mechanisms bouts focused on smaller range segments, involve questions concerning processing aging networks.
