Early exploratory behaviors have been proposed to facilitate children's learning, impacting motor, cognitive, language, and social development. This study related the performance of behaviors used to explore oneself to behaviors used to explore objects, and then related both types of exploratory behaviors to motor, language, and cognitive measures…

We report two studies that investigated the continuity and stability of maternal mind-mindedness (MM) across different times, contexts, and relationships, and also examined child communicative development in the second year of life. Three main findings emerged. First, the percentages of appropriate mind-related comments (AMRC) decreased between 16…

This longitudinal multiple case study explores children's transitions within early childhood education and care (ECEC) in Finland. In ECEC children typically transition from one group or center to another. This study explores how physical, social and philosophical discontinuities and continuities constitute these transitions. Five focus children's…

Executive functioning (EF) is a key cognitive process for development. Little is known about EF in Kindergarten children at risk for developmental coordination disorder (DCD), despite this age being one of the most critical and intensive period of motor and cognitive development. In our investigation we compared EF in kindergarten children at risk…

This research examined developmental continuity between "cruising" (moving sideways holding onto furniture for support) and walking. Because cruising and walking involve locomotion in an upright posture, researchers have assumed that cruising is functionally related to walking. Study 1 showed that most infants crawl and cruise concurrently prior…

Recent studies on nonsymbolic arithmetic have illustrated that under conditions that prevent exact calculation, adults display a systematic tendency to overestimate the answers to addition problems and underestimate the answers to subtraction problems. It has been suggested that this "operational momentum" results from exposure to a…

To assess predictive relations between joint attention skills, intention understanding, and mental state vocabulary, 88 children were tested with measures of comprehension of gaze and referential pointing, as well as the production of declarative gestures and the comprehension and production of imperative gestures, at the ages of 7-18 months.…

On belief-desire reasoning tasks, children first pass tasks involving true belief before those involving false belief, and tasks involving positive desire before those involving negative desire. The current study examined belief-desire reasoning in participants old enough to pass all such tasks. Eighty-three 6- to 11-year-olds and 20 adult…

This study traces patterns of attendance, times of arrival and departure, and policies and practices surrounding enrollment and moving children from classroom to classroom in a child care center. It appears that children's efforts to acquire competence in developing friendships with their peers not only depends on their own capacities, but is also…

The present study investigates whether the Early Development Instrument (Offord & Janus, 1999) measures school readiness similarly across different groups of children. We employ ordinal logistic regression to investigate differential item functioning, a method of examining measurement bias. For 40,000 children, our analysis compares groups…

In this book, the author reveals the creative force of children's narrative imagination and shows how this develops through childhood. He provides a new and powerful understanding of the significance of narrative for children's intellectual growth and for learning and teaching. The book explores a series of real stories written by children between…

Despite the importance of learning abilities and disabilities in education and child development, little is known about their genetic and environmental origins in the early school years. We report results for English (which includes reading, writing, and speaking), mathematics, and science as well as general cognitive ability in a large and…

Examined evidence for transitions in first and second graders' analogical reasoning, over a six-month period. Found strong evidence for bimodality in test performance frequency distributions and weaker evidence for inaccessibility in frequency distributions. Transitional subjects showed a temporary increase of inconsistent solution behavior and…

This study investigated the following questions: (1) Are newborn individual differences relevant for infant developmental outcomes?; (2) Can any continuity be found between neonatal and infant behavioral characteristics?; (3) Are maternal behavioral styles influenced by the newborn's individual characteristics?; and (4) Do initial maternal…

Two experiments used a formal model of developmental discontinuity derived from catastrophe theory to test whether the transition from Rule I to Rule II on the balance scale task proceeds discontinuously from ages 6 to 10, focusing on five catastrophe flags. Found that bimodality, inaccessible region, hysteresis, and sudden jump were clearly…
