First-order theory of mind (ToM) development has shown to conform to a Guttman scale, with desire reasoning developing before belief reasoning. There have been attempts to test for internal consistency and scalability in advanced ToM, but not over a broad age range and only with a limited set of tasks. This 2-year longitudinal study (N = 155;…

This study investigated relations between parent teaching, cumulative instability/chaos and school readiness in a group of 130 children attending a Head Start preschool. Cumulative instability/chaos negatively predicted fall school readiness as well as spring school readiness. Parent teaching did not predict fall school readiness but did predict…

The present study investigated whether Mandarin-speaking preschool children with autism spectrum disorders (ASD) were able to use prosodic cues to understand others' communicative intentions. Using the visual world eye-tracking paradigm, the study found that unlike typically developing (TD) 4-year-olds, both 4-year-olds with ASD and 5-year-olds…

Many recent studies about preschool early language and literacy skills utilize multiple assessments to identify young children who require additional multitiered instructional support. Although the use of a single screening instrument may be efficient but overidentify children in need of intervention, the universal administration of multiple…

Experiences of contingent responsivity during shared book reading predict better learning outcomes. However, it is unclear whether contingent responsivity from a digital book could provide similar support for children. The effects on story recall and engagement interacting with a digital book that responded contingently on children's vocalizations…

Purpose: Language production, a dynamic process involving real-time language processing, is crucial for children's language and communication development. To explore the early development of children's real-time language production, this study investigated Chinese preschool children's pausing strategies in narratives and their associations with…

The Student Oral Language Observation Matrix (SOLOM) is an assessment of oral language skills. The aim of this study was to examine psychometric properties of the SOLOM for preschoolers through (a) use of internal consistency methods to assess the reliability of the scores from the SOLOM and (b) examination of criterion-related validity by…

To successfully pull a practical joke on someone, children need to understand that their victims do not know what they themselves know, be able to intentionally manipulate others' beliefs, and maintain a straight face to safeguard the integrity of the joke. This study examined the relationship between children's developing theory of mind (ToM),…

Despite the important role assigned to analogical reasoning (AR) in cognition and language, the relationship between this ability and language skills in the emergent literacy period has not been sufficiently studied, especially in Spanish speakers. To explore this link, we examined two modalities of AR (verbal and non-verbal) as predictors of…

Previous research has shown that using gestures helps children remember more information. Here, we designed two studies to test whether children who gesture tend to rely on visuospatial cognitive resources more than children who do not gesture. We also test whether children who gesture demonstrate more creativity in their narrative productions.…

With nearly half of all children under age six living in poverty, it is imperative to explore the development of income-related childhood aggression. Here, we specifically examine how family socioeconomic status (SES) relates to children's physical and relational aggression, and how this relation may be moderated by burgeoning social cognition.…

The purpose of this study was to explore pre-readers' comprehension of a story with competing character goals. Fifty-eight children in three age groups (2½-3 years; 3-4 years; and 4-5 years) were read a story in which the protagonist's goal was unstated and conflicted with the goal of the secondary character. Understanding of explicit story…

Effective questioning helps preschoolers to reason verbally during philosophical group discussions. The aim of this study was to identify which researcher's questions preschoolers respond to with verbal reasoning during such discussions. The data were collected through video-recorded group discussions. A total of 1567 questions and 1119 verbal…

There is general agreement that humans represent numerical, spatial, and temporal magnitudes from early in development. However, there is disagreement about whether different magnitudes converge within a general magnitude system and whether this system supports behavioral demonstrations of cross-magnitude interactions at different developmental…

Children diagnosed with autism spectrum disorder (ASD) are at increased risk of persistent language and literacy difficulties. This study investigated the effectiveness of an 8-week parent-implemented shared book reading intervention designed to change parent and child book reading behaviours. Sixteen parents and their preschoolers on the autism…
