The interaction between a mother and child stands as one of the most profound and intricate human connections, weaving a rich tapestry of behavioral and emotional bonds during the formative years. Although mother-child interactions have received substantial attention in the developmental science literature, few studies have tapped into the…

Researchers and practitioners need robust measurement tools for evaluating knowledge of child development to better support parents and their children during pregnancy and the transition to parenthood. We addressed this need by evaluating the psychometric properties of the Domains of Development Instrument (DoDI) for measuring knowledge of…

Stimulus over-selectivity is said to have occurred when only a limited subset of the total number of stimuli present during discrimination learning controls behavior, thus, restricting learning about the range, breadth, or all features of a stimulus. The current study investigated over-selectivity of 100 typically developing children, aged 3-7…

Emotion comprehension (EC), theory of mind (ToM), and language are particularly important aspects of child development. In recent years, there has been increasing interest in understanding how these three variables are related to preschool children. However, results have been contradictory, and it is not clear how EC, ToM, and language are…

Solitude occurs from childhood to old age. In this special issue introduction, we offer a lifespan perspective on matters of solitude with the aim to point to pertinent issues in the field. We propose that solitude serves important functions that may vary across different times in life and that solitude needs to be considered in the context in…

Maternal gatekeeping is characterized by the extent to which mothers engage in behaviors that ultimately serve to inhibit (i.e., gate close) or encourage (i.e., gate open) father involvement in childrearing. This study considered direct and indirect associations between observed and reported maternal gatekeeping and children's social-emotional…

Findings from previous cross-sectional studies showed that while toddlers around their first birthday imitate selectively, that is, they systematically omit some kinds of target action steps or they copy only the goal, but not the means of the modeled actions, older toddlers imitate more exactly. The aim of the present article is to provide…

Sentiment analysis is a computational method that automatically analyzes the valence of massive quantities of text. Basic sentiment analysis involves extracting and counting emotionally-laden keywords from passages of text (e.g., "hate," "love," "happy," "sad"). This study describes using sentiment analysis…

The purpose of this research was to determine the influence of two subcomponents of auditory short-term memory on the developmental trajectories of behavior problems. The sample included 7,058 children from the NLSY79--Children and Young Adult survey between the ages 5 and 14 years. Results suggested that anxious/depressed behavior increases…

Moderate, yet relatively consistent, associations between cognitive performance and shyness have been reported throughout the child and adult literatures. The current study assessed longitudinal associations between cognition (i.e., executive functioning) and parent-report temperamental shyness from infancy to early childhood and used temporal…

This study investigates whether preschool-aged children show consistent patterns of behaviour in conflicts with their siblings. Consistency was assessed at the nomothetic (i.e., group), idiographic (i.e., individual), and idiosyncratic (i.e., consistent patterns that differed from the norm) levels. We examined conflicts between 19 2-year-old and…

Anxiety disorders are among the most prevalent psychiatric problems in children and adolescents. The present article summarizes the main evidence that has accumulated on the pathogenesis of childhood anxiety disorders during the past two decades. Various risk and vulnerability factors (e.g., genetics, behavioral inhibition, disgust sensitivity,…

The goal of the study was to examine the developmental course of sleep consolidation from infancy to preschool. The sleep of 50 healthy infants aged 3 months was recorded, at home, with actigraphs (computerised activity monitors). Follow-up recordings were carried out at 6, 9, 12, 20, and 42 months (due to attrition and occasional technical…

Discusses ambiguities in research that arise from the fact that chronological age reflects different components. Considers methodology, components of age as indices of different aspects of development, differential effects of experiences according to their timing, and maturational delay. (RJC)

Cross-cultural differences in emotional expressions following disappointment were examined in 59 Chinese American (CA) and 58 European American (EA) children. Children aged four or seven participated in a disappointing gift situation. Dimensions of expressive behaviors following disappointment were coded and included positive, negative, social…
