Most extant research on parental socialization for child appreciation has either conflated appreciation and gratitude or fallen foul of a conceptual-operational mismatch, yielding theoretical controversies and inconsistent results. Using a matched conceptualization and operationalization of appreciation and based on three waves of data from 496…

The extant literature on the use of autonomy support during caregiver-child conversations has focused primarily on conversations about fun, shared experiences, with limited consideration of unshared experiences or attention toward the role of conversation context. The present study examined how autonomy support, conversation context, and child age…

We investigated how educators, mothers and children used temporal language in reminiscing and future talk conversations. Participants initially included 40 educator-younger child dyads (27-36 months) and 45 educator-older child dyads (48-60 months) from early childhood centres in Sydney, Australia. Educators were asked to nominate and discuss four…

Shared intentionality theory posits that at age 3, children expand their conception of plural agency to include 3- or more-person groups. We sought to determine whether this conceptual shift is detectable in children's pronoun use. We report the results of a series of Bayesian hierarchical generative models fitted to 479 English-speaking…

The aim of this study is twofold: To examine if deafness is invariably associated with deficits in executive function (EF) and to investigate the relationship between sign language proficiency and EF in deaf children of deaf parents with early exposure to a sign language. It is also the first study of EF in children acquiring Polish Sign Language.…

This study explores the cognitive development of children born to adolescent mothers within South Africa compared to existing reference data, and explores development by child age bands to examine relative levels of development. Cross-sectional analyses present data from 954 adolescents (10-19 years) and their first-born children (0-68 months).…

Recent evidence suggests that deaf children with CIs exposed to nonnative sign language from hearing parents can attain age-appropriate vocabularies in both sign and spoken language. It remains to be explored whether deaf children with CIs who are exposed to early nonnative sign language, but only up to implantation, also benefit from this input…

This study aims to examine the effect of kangaroo care on Vulnerable Infant Syndrome (VIS) in the mother. The sample group consisted of 58 preterm infants, 27 of whom were control and 31 were experimental groups. Data were collected using the question form, the Vulnerable Baby Scale (VBS), the Edinburgh Post Partum Depression Scale (EPDS), the…

Over time, people who spend a lot of time together (e.g., roommates) begin sounding alike. Even over the course of short conversations, interlocutors often become more acoustically similar to one another. This phenomenon -- known as phonetic alignment -- has been well studied in adult interactions, but much less is known about alignment patterns…

A relatively large number of children with autism spectrum disorder (ASD) exhibit disruptive behavioral problems. While accumulating data have shown behavioral parent training programs to be efficacious in reducing disruptive behaviors for this population, there is a dearth of literature examining the impact of such programs across the range of…

Vocabulary checklists completed by caregivers are a common way of measuring children's vocabulary knowledge. We provide evidence from checklist data from 31 children with and without autism spectrum disorder. When asked to report twice about whether or not their child produces a particular word, caregivers are largely consistent in their…

When communicating with other people, adults reduce or lengthen words based on their predictability, frequency, and discourse status. But younger listeners have less experience than older listeners in processing speech variation across time. In 2 experiments, we tested whether English-speaking parents reduce word durations differently across…

Research in language development has only recently begun to focus on the inherent variability of language. Previous studies have explored at what age children begin to produce variable linguistic forms and how these forms progress through development. While children produce adult-like variation early on, some variable forms take longer to acquire…

This study evaluated a parent-mediated preventive intervention for children's literacy skills 1 year after participation. Parents of 3 1/2 to 4 1/2-year-old-children (n = 69) recruited through early childhood centers were randomly assigned to one of three conditions: (a) a target shared reading condition emphasizing phonological awareness…

The aim of this study was to document the impacts of an environmental education program with adolescents and older adults on attitudes about old age, and to investigate possible associations of these attitudes with age group, economic class, residing with grandparents, and grandparents' contribution to parenting. We investigated adolescents…
