The acquisition and use of relative clauses in Turkish-learning children's conversational interactions: a cross-linguistic approach
(Cambridge University Press, 2019) Uzundağ, Berna A.; Küntay, Aylin C.
Using a cross-linguistic approach, we investigated Turkish-speaking children's acquisition and use of relative clauses (RCs) by examining longitudinal child-caregiver interactions and cross-sectional peer conversations. Longitudinal data were collected from 8 children between the ages of 8 and 36 months. Peer conversational corpus came from 78 children aged between 43 and 64 months. Children produced RCs later than in English (Diessel, 2004) and Mandarin (Chen & Shirai, 2015), and demonstrated increasing semantic and structural complexity with age. Despite the morphosyntactic difficulty of object RCs, and prior experimental findings showing a subject RC advantage, preschool-aged children produced object RCs, which were highly frequent in child-directed speech, as frequently as subject RCs. Object RCs in spontaneous speech were semantically less demanding (with pronominal subjects and inanimate head nouns) than the stimuli used in prior experiments. Results suggest that multiple factors such as input frequency and morphosyntactic and semantic difficulty affect the acquisition patterns.

Maternal behaviors mediate the relationship between socioeconomic status and joint attention
(Elsevier Ltd, 2021) Koşullu, Sümeyye; Küntay, Aylin C.; Uzundağ, Berna A.
Socioeconomic status (SES) is strongly related to parental behaviors and the quality of parent-child interactions. We examined whether through maternal behaviors, SES is linked to joint attention (JA), an important form of parent-child interactions predicting language development. At 12 months, 50 mother-infant dyads were video-recorded during 5-min free play. We coded for maternal behaviors (sensitivity, cognitive stimulation, positive affect, negative affect, control) and JA characteristics (frequency, duration, initiated by maternal following/directing, passive/coordinated, terminated by mother/infant). Mediation analyses showed that higher-SES mothers were more sensitive, less controlling, provided more cognitive stimulation, and displayed more positive affect resulting in JA interactions of higher quality (e.g., initiated by maternal following rather than directing infant's attention) and quantity (i.e., more time spent in JA). These findings contribute to current literature by revealing maternal behaviors as a mediator between SES and mother-infant JA interactions.
