Three preregistered experiments, conducted in 2021, investigated whether English-speaking American preschoolers (N = 120; 4-6 years; 54 females, predominantly White) and adults (N = 80; 18-52 years; 59 females, predominantly Asian) metonymically extend owners' names to owned objects--an extension not typically found in English. In Experiment 1, 5-…

The social validity of autism behavioral intervention has been questioned. Naturalistic Developmental Behavioral Interventions (NDBIs) attempt to address some concerns, but it is unclear whether autistic people consider NDBIs socially valid. Social validity of an NDBI, Pivotal Response Treatment (PRT), was investigated through autistic adults…

There is little research regarding autistic adult, parent and professional perspectives on support goals for young autistic children. A total of 87 autistic adults, 159 parents of autistic children, and 80 clinical professionals living in New Zealand and Australia completed a survey about the appropriateness and importance of common support goals…

Causation is a core feature of human cognition and language. How children learn about intricate causal meanings is yet unresolved. Here, we focus on how children learn verbs that express causation. Such verbs, known as lexical causatives (e.g., break and raise), lack explicit morphosyntactic markers indicating causation, thus requiring that the…

Young children's (n = 108) and adults' (n = 40) ability to compute ad-hoc quantity conversational implicatures was assessed using a new implicit task that relied on eye-tracking. The children were 2 and 5 years old. Looking times reveal that all participants interpreted simple references by relying on implicatures. However, 2-year-olds failed to…

Using an intersectional analysis, this article critically analyses implied and expressed norms to identify perceptions of appropriate behaviour in children's play, and to explore how social communicative arenas such as Internet forums construct knowledge and values. Adults' responses to an incident that occurred amongst a group of children in…

This paper provides a discourse analysis of 12 Swedish sexuality education texts intended for preschool practitioners and published between 1969 and 2021. Using Fairclough's framework, we identify three discourses about children's sexual play in relation to children's sexual agency in the texts: child sexuality as encouraged and entangled with…

Only a very few studies to date have comprehensively assessed children's knowledge of sexuality. In this study, we examined the level of sexual knowledge among children aged 3-6 years in Finland. We analysed children's explanations of what they saw in drawings related to genital naming, conception and childbirth, safety skills, and adult sexual…

This study investigated the development of rapid visual object categorization. N = 20 adults (Experiment 1), N = 21 five to six-year-old children (Experiment 2), and N = 140 four-, seven-, and eleven-month-old infants (Experiment 3; all predominantly White, 81 females, data collected in 2013-2020) participated in a fast periodic visual stimulation…

Cross-situational word learning, the ability to decipher word-referent links over multiple ambiguous learning events, has been documented across development and proposed to be key to vocabulary acquisition. However, this work has largely focused on learning from one-to-one structure, where each referent is consistently linked with a single label.…

Prior theoretical and empirical studies have linked the first 3 years of children's life with later life outcomes. One primary explanation is the critical role these experiences play in children's early brain development (including their early language and cognitive abilities) and subsequent schooling achievement. The current study is a registered…

Deaf people use visual language and communication strategies naturally. Moreover, hearing people (both young children and adults) can also benefit from sign language and the visual strategies that deaf parents and teachers use with young children, an example of deaf gain. This paper will provide an overview of the concept of deaf gain, review…
