In Study 1, 103 children ages 4 through 10 answered questions about their concept of and belief in luck, and completed a story task assessing their use of luck as an explanation for events. The interview captured a curvilinear trajectory of children's belief in luck from tentative belief at age 4 to full belief at age 6, weakening belief at age 8,…

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…

There is clear evidence that the COVID-19 pandemic had significant negative effects on the learning and development of school-age children in the United States, with disproportionate impacts on children from racially, ethnically, and socioeconomically marginalized groups. There is less consistent evidence on the extent to which the pandemic…

Background/rationale: There is clear evidence that the COVID-19 pandemic had significant negative effects on the learning and development of school-age children in the United States, with disproportionate impacts on children from racially, ethnically, and socioeconomically marginalized groups (Irwin et al., 2022). There is less consistent evidence…

When linguistic input contains inconsistent use of grammatical forms, children produce these forms more consistently, a process called "regularization." Deaf children learning American Sign Language from parents who are non-native users of the language regularize their parents' inconsistent usages. In studies of artificial languages…

The present study investigated children's internal state language during play with their sibling and friend across early and middle childhood. Specifically, the category type of internal state language (e.g., cognitions and goals), referent (e.g., own and other), and associations with children's birth order were examined. A total of 65 (T1: Time…

Background: Individuals with Williams syndrome (WS) show a disharmonic linguistic profile with a clear pattern of strengths and weaknesses. Despite their sociable nature, atypical socio-communicative abilities and deficits in communication and relationship with others have been found. Aim: The aim of the present study was to investigate whether…

Parent-child interactions and characteristics of mothers' child-directed language have been related to children's linguistic development. Studies on parent-child interactions in Turkey have generally focused on children. There have not been many researches on Turkish motherese. This study addresses this gap by exploring the properties of Turkish…

Verbal and figurative classification tasks were presented to 30 blind and 30 sighted children (ages 6 to 11). Although younger blind children were significantly less efficient on tasks, older ones reached or were close to the level of their sighted peers. Analysis illustrates how the blind children adjusted their conceptual knowledge to their…

Preschool children were given a memory task that required repeating a list of animal names and a sentence imitation task. Results confirmed a relationship between word span and language imitation in younger preschool children and the notion of a memory constraint on early spontaneous language. Increasing mastery of linguistic rules appeared to…

Two experiments showed that: 5- and 6-year-old listeners have difficulties with spatial reference if it includes "left" and "right"; and 7-year-olds understand this limitation on the comprehension skill of younger children and make appropriate allowances by using more landmarks instead. (CB)

The present study investigates the performance of 96 Cantonese-speaking three- to five-year-old preschoolers on three false belief tasks--a deceptive object, a change of location, and an unexpected contents task encompassing a variety of task factors. Most importantly, the research examines the possibility that false belief performance depends on…

A naturalistic study looked at the acquisition of English by two Japanese boys, aged 4 and 8 years, during a 2.5-year stay in the United States. Data were collected through observation and transcription of spontaneous speech in daily life. Analysis included a variety of features of language use and of the acquisition process, including attitudes…
