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.…

Scalar implicatures (SIs) lie at the interface between semantics and pragmatics, and therefore have evoked great interest for language acquisition research. Many acquisition studies show that young children know the literal semantics of scalar items (like "some", "might", "start" and "or") but have…

A large and growing body of work has documented robust illusions of area perception in adults. To date, however, there has been surprisingly little in-depth investigation into children's area perception, despite the importance of this topic to the study of quantity perception more broadly (and to the many studies that have been devoted to studying…

The study aimed at exploring the levels of emotional regulation and social competence among kindergarten children. Further, the relationship between emotional regulation and social competence and its sub-domains: (overall emotional adjustment, social interactions with peers, and social interaction with adults). Furthermore, the significant…

Many words are associated with more than a single meaning. Words are sometimes "ambiguous," applying to unrelated meanings, but the majority of frequent words are "polysemous" in that they apply to multiple "related" meanings. In a preregistered design that included 2 tasks, we tested adults' and 4.5- to 7-year-old…

Distractibility is the propensity to behaviorally react to irrelevant information. Although children are more distractible the younger they are, the precise contribution of attentional and motor components to distractibility and their developmental trajectories have not been characterized yet. We used a new behavioral paradigm to identify the…

Individuals track probabilities, such as associations between events in their environments, but less is known about the degree to which experience--within a learning session and over development--influences people's use of incoming probabilistic information to guide behavior in real time. In two experiments, children (4-11 years) and adults…

To track the course of development in children's fine-grained perception of Mandarin tones, the present study explored how categorical perception (CP) of Mandarin tones emerges along age among 70 four- to seven-year-old children and 16 adults. Prominent discrimination peaks were found for both the child and the adult groups, and they were well…

The present study is designed to investigate whether children's difficulties with subject-to-subject raising (StSR) are due to intervention effects. We examine English-speaking children's comprehension of StSR with "seem" and Spanish-speaking children's comprehension of StSR with "parecer" 'seem,' a configuration never before…

Although it has been proposed that maintenance of verbal information in adults' working memory relies on two strategies, articulatory rehearsal and attentional refreshing, little is known about the interplay of these strategies in children. To examine strategy changes around the age of seven, children were asked to maintain digits during a…

Purpose: Four measures of children's developing robustness of phonological contrast were compared to see how they correlated with age, vocabulary size, and adult listeners' correctness ratings. Method: Word-initial sibilant fricative productions from eighty-one 2- to 5-year-old children and 20 adults were phonetically transcribed and acoustically…

This study investigated the integration of word- and phrase-level prominences in speech produced by twenty-five school-aged children (6;2 to 7;3) and twenty-five adults. Participants produced disyllabic number words in a straight count condition and in two phrasal conditions, namely, a stress clash and non-clash phrasal context. Duration and…

Mobile applications are popular among young children, yet there is a dearth of studies examining their impact on learning and development. A systematic review identified 19 studies reporting learning effects on children 2 to 5 years old. The number of children participating in experimental, quasi-experimental, or mixed-method studies was 862 and…

Sotos syndrome is a congenital overgrowth disorder with an incidence of approximately 1 in 14,000. This study investigated behavioural characteristics of ASD within a large cohort of individuals with Sotos syndrome (n = 78). As measured by the Social Responsiveness Scale, second edition (SRS-2), 65 participants (83.33%) met clinical cut-off…

This article presents several empirical studies of syntactically encoded evidentiality in English. The first part of our study consists of an adult online experiment that confirms claims in Asudeh & Toivonen (2012) that raised Perception Verb Similatives (PVSs; e.g. "John looks like he is sick") encode direct evidentiality. We then…
