This study probed praising among preschoolers in natural settings and investigated their developmental changes. In study 1, teachers in preprimary educational facilities answered queries about the frequency and described episodes of praising among preschoolers. The results indicated that children approximately 3-year-old commonly praised friends,…

In this paper, we investigated whether Canadian preschoolers prefer to learn from a competent robot over an incompetent human using the classic trust paradigm. An adapted Naive Biology task was also administered to assess children's perception of robots. In Study 1, 3-year-olds and 5-year-olds were presented with two informants; A social, humanoid…

The Study of Social and Emotional Skills (SSES) is an international effort led by the Organization for Economic Co-operation and Development (OECD). The Houston Independent School District (HISD) served as the only U.S. site for this study. Over 6,400 10-year-old and 15-year-old students from 119 HISD schools participated in the SSES in the fall…

Children's hypothetical reasoning about a complex and dynamic causal system was investigated. Predominantly White, middle-class 5- to 7-year-old children from the Greater Toronto Area learned about novel food chains and were asked to consider the effects of removing one species on the others. In Study 1 (N = 72; 36 females, 36 males; 2018),…

The aim of this study is to investigate the aerobic and anaerobic powers of students in different grades of the schools and describe the correlation between these powers. Upon the written approval of Samsun National Education Management, this study was carried out with the voluntary participation of 120 females and 120 males aged 11-16, who were…

Caregivers' moral reactions to young children's moral transgressions are informative environmental responses for children's developing understanding of morality. One central question concerns by which age parents hold their children responsible for moral transgressions. This study indirectly investigated this question by having parents and…

The aim of this study was to validate a teacher rating scale (TRS-EN) for assessing early numeracy skills and for identifying mathematically low-performing 3- and 4-year-old children. Fifty-six preschool teachers assessed children's (3-year-olds = 127; 4-year-olds = 145) numerical relational, counting, and basic arithmetic skills. Construct…

To study the role of executive function (EF) in the early development of aggression, the role of cool and hot EF skills at 5 years old, in the development of physical and relational aggression between 5 and 6 years old, was explored. Typically developing children (N = 80) completed tasks assessing their cool (inhibition, working memory, planning)…

The present study aimed to determine whether exceptional items in human figure drawings (HFDs) can serve the identification process of talents and (educational) needs of children with high intellectual abilities. Participants were 152 children aged 4 to 6 years at the time of drawing. After 2 years, 85 had received regular curriculum (the…

Three-year-old children are seldom the focus in studies about supplemental early literacy instructional support. This study examines 3-year-old children's potential need for additional early literacy support, extending and replicating a previous investigation that identified prekindergarten children (i.e., 4-year-olds) in Head Start classrooms for…

To successfully navigate an uncertain world, one has to learn the relationship between cues (e.g., wind speed, atmospheric pressure) and outcomes (e.g., rain). When learning, it is possible to actively manipulate the cue values to test hypotheses about this relationship directly. Across two studies, we investigated how 5- to 7-year-olds actively…

This study explored teaching early mathematical skills to 3- to 7-year-old children in early childhood education and care (ECEC) and pre-primary education. Teachers in ECEC (N = 206) answered a web survey. The first aim was to determine whether teaching frequency or pedagogical awareness of teaching early mathematical skills varied according to…

The ability to bind, or link, different aspects of an experience in memory undergoes protracted development across childhood. Most studies of memory binding development have assessed extraobject binding between an object and some external element such as another object, whereas little work has examined the development of intraobject binding, such…

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 purpose of the study is to reveal the predictive effect of aggression levels of four-year-old children on their peer victimization levels and to determine their aggression levels according to gender. The sample group of the study consisted of 186 four-year-old children attending preschool education in Pamukkale district of the province of…
