In this longitudinal study, we investigated the factor structure and stability of early-life temperament in a German sample, using three measures developed within Rothbart's psychobiological approach. Temperament was measured using the Infant Behavior Questionnaire Revised (IBQ-R) at the ages of 6 and 12 months, the Early Childhood Behavior…

The secure base phenomenon was ascribed to changes in exploration observed during Ainsworth's Strange Situation Procedure (SSP), related to the quality of the attachment relationship. However, infant temperament was not taken into consideration. The current study aims to replicate Ainsworth's findings regarding infant exploration and attachment…

The way that mothers talk about the past (reminisce) with young children is linked to key memory, language, and socioemotional outcomes. The present research explored the role of a range of child, maternal, socioeconomic, and cultural factors that predict maternal reminiscing style, with a particular focus on maternal personality and child…

Infants attend daycare at an early age, which raises questions about children's sensitivity to the childcare environment and the role of different temperamental traits in their development in the early years. In a two-year longitudinal study with parent- and caregiver-reported data for Dutch children at the age of 1 and 2 years (120 children from…

The purpose of the current study was to use the infant sibling design to explore whether proband traits of autism and ADHD could provide information about their infant sibling's temperament. This could help us to gain information about the extent to which infant temperament traits are differentially associated with autism and ADHD traits. We used…

Data from 83,423 parent reports of temperament (surgency, negative affectivity, and regulatory capacity) in infants, toddlers, and children from 341 samples gathered in 59 countries were used to investigate the relations among culture, gender, and temperament. Between-nation differences in temperament were larger than those obtained in similar…

This study examined the development of caregiver mind-mindedness--defined as the propensity to see one's child as an agent with an independent mind--across the first 1,000 days of life. At four timepoints (i.e., third trimester of pregnancy, 4, 14, and 24 months postpartum), 384 first-time mothers (M[subscript age] = 32.55, SD = 3.63 years) and…

Background: Although plausible links between language development and personality have been suggested, longitudinal studies of these associations into adulthood have not been conducted. Aim: To investigate whether children's age at attaining language milestones is associated with later adult personality. Methods: Mothers' of 8,400 children from…

Teacher-family partnerships are crucial elements of high-quality early childhood education. The factors influencing these partnerships, particularly for children under age 3, are not well known. This study compares teachers' and mothers' perspectives on their partnership and the ideal practices they would like to see implemented. Additionally, it…

The ability to regulate one's emotions and behaviors is essential for adaptive functioning in society. We investigated whether parental mind-mindedness--parents' tendency to treat their children as mental agents--in infancy and toddlerhood predicts school-age children's self-regulation. The sample consisted of 125 mostly Dutch and White families.…

Child's crying is the stimuli serving the development of a child-parent relationship through evoking child-oriented and parent-oriented parental reactions. Individual differences in parental reactions to crying have been partly explained by parental and child's temperament. We conducted two studies to verify the predicting effects of temperamental…

This study identified the correlations between the temperament types of infants and their cries evoked by external pain stimuli. We examined infant cries evoked by vaccinations and analyse the volume and types of audio frequency fluctuation of the cries. The Infant Temperament Questionnaire is filled out by the parents. Statistical analyses of…

Several researchers have found that media exposure through books or electronic media contribute to preschoolers' development. However, research with behavioral measures and during the first years of life have not been carried out in Latin American contexts. The aim of the following research was to evaluate the relations between media exposure…

Early temperament predicts various aspects of development. In large-scale studies, temperament is often assessed via parental report because naturalistic and structured observations are costly and bear the risk of subject loss. However, the validity of such parental reports has been disputed repeatedly. This article compared parental reports on…

This study aimed to examine the effect of attachment security in 17-month-olds on their peer play interactions and behavioural problems at ages 4 and 6 years, respectively, in Korea. By employing structural equation modelling, we analyzed the data of 183 children and their mothers, which were extracted from the Panel Study on Korean Children…
