The standard view on Theory of Mind (ToM) is that the mastery of the false belief (FB) task around age 4 marks the ontogenetic emergence of full-fledged meta-representational ToM. Recently, a puzzling finding has emerged: Once children master the FB task, they begin to fail true belief (TB) control tasks. This finding threatens the validity of FB…

Metacognitive reasoning is central to decision-making. For every decision, we can also judge our trust in that decision, or our level of "confidence." The mechanisms and representations underlying reasoning about confidence remain debated. We test whether children rely on "processing fluency" to infer their own confidence: do…

This study aims to preliminarily validate the Italian version of the Coparenting Relationship Scale for Children (CRS-C) with 141 mothers, 141 fathers, and 141 children (48.6% males) aged 8-14 years. We tested the factorial structure of the CRS-C, which included five factors (support, endorsement, undermining, agreement, and exposure to conflict),…

Autistic individuals are twice as likely to meet criteria for anxiety than neurotypical children; yet we lack understanding of early presentations of anxiety in young autistic children, especially those with cognitive impairment. This study is the first to utilize an autism-specific anxiety diagnostic interview with 28 preschool cognitively…

Children's fuzziness leads to increased variance in the data, data loss, and high dropout rates in developmental studies. This study investigated the importance of 20 factors on the person (child, caregiver, experimenter) and situation (task, method, time, and date) level for the data quality as indicated via the number of valid trials in 11…

When children first learn to count, what do they understand about the structure of the count system? The present study investigated English-speaking children's ability to generalize the rules that structure their count list to novel contexts. A total of N = 86 children (3;0-6;11) completed a battery of tasks aimed at measuring their understanding…

Language exposure is an important determiner of language outcomes in bilingual children. Family language strategies (FLS, e.g., one-parent-one-language) were contrasted with parents' individual language use to predict language exposure in 4-31-month-old children (50% female) living in Montreal, Quebec. Two-hundred twenty one children (primarily…

International guidelines on sexual health education suggest that parents should be the primary educators in their children's sexuality education, considering that sexuality education is a lifelong process that begins in early childhood and continues into adulthood. The study aimed to investigate the relationships among parental self-efficacy,…

Purpose: Stuttering is associated with clinically significant social anxiety, which emerges during early childhood for some, but not all, children who begin to stutter. The purpose of this review article is to develop a model of social anxiety development during early childhood stuttering and to present an empirical method by which it can be…

Beyond correlational studies exploring the benefits of nature exposure, there have been studies assessing interventions that aim to improve nature connection in children and adolescents. A feeling of connection with nature or 'nature connectedness' describes our attitude towards nature, primarily reflecting the emotional, cognitive, and…

Background: Few studies have explored community participation for autistic adults, with or without intellectual disability. This study aims to investigate how autistic adults participate in the community, and the childhood and adulthood factors that predict community participation in adulthood. Method: Eighty-four autistic adults (mean age 34…

Learning takes time: Performance usually starts poorly and improves with practice. Do children intuit this basic phenomenon of skill learning? In preregistered Experiment 1 (n = 125; 54% female; 48% White; collected 2022-2023), US 7- to 8-year-old children predicted improved performance, 5- to 6-year-old children predicted flat performance, and…

Background: The transmission of attachment from parent to child is a well-known phenomenon. Previous research documented evidence supporting the transmission of attachment from parents to their children, with parental sensitivity serving a mediating role. Nevertheless, a "transmission gap" exists. Objective: In the current pre-registered…

This research with two studies examined whether young children's moral judgments of honesty and dishonesty predict their actual cheating behavior. Participants were 200 children aged 3-6 years (2021-2022. Study 1: N = 80, M[subscript age] = 4.96, 40 girls; Study 2: N = 120, M[subscript age] = 4.98, 60 girls; all middle-class Han Chinese). Children…

Children learn language by listening to speech from caregivers around them. However, the type and quantity of speech input that children are exposed to change throughout early childhood in ways that are poorly understood due to the small samples (few participants, limited hours of observation) typically available in developmental psychology. Here…
