Early childhood

Early childhood is a vital stage of human development. It follows infancy and ends before middle childhood begins. In psychology, this period is often defined from birth until age five or six. This timeframe covers infancy, Pre-K, kindergarten, and first grade. It also includes toddlerhood and a period known as play age. While it is related to early childhood education, they are not the same thing. Early childhood education is a specific category used to support children from nursery school through third grade.

One way to understand this stage is through the work of Jean Piaget. He identified four distinct stages of cognitive development. The first is the sensorimotor stage, which lasts from birth to age two. During this time, children use hearing, seeing, touching, and reaching to learn. Next is the preoperational stage, occurring between ages two and seven. In this stage, children form thoughts without using logic. They often think very literally and may exhibit egocentrism. This means they struggle to understand that others have different beliefs.

As children grow, they move into the concrete operational stage from ages seven to 11. This stage involves more rational and developed thoughts. Children begin to understand the organization and purpose of different situations. The final stage is the formal operational stage, which begins at age 11. During this time, individuals can create their own ideas and rationalize complex situations. They can form opinions that are supported by logic. This is considered the most important stage for learning in adulthood.

Physical growth is also incredibly rapid during early childhood. The brain undergoes significant synaptic growth and myelination of neural fibers. This is especially true in the frontal lobes. Between the ages of two and six, the brain grows from 70% to 90% of its adult weight. This physical expansion leads to a surge in cognitive abilities. By age five, many children master hand-to-eye coordination and begin speaking properly. Physical development follows a specific pattern involving two types of skills.

Children develop gross motor skills before they master fine motor skills. Gross motor skills involve large muscles used for walking and running. Fine motor skills involve small muscles used for drawing, writing, or picking up objects. Social-emotional growth also happens simultaneously. This includes developing a sense of self and forming relationships. Children also begin to notice gender differences around age three. Research shows that boys often show more physical aggression. In contrast, girls may show more social aggression, such as name-calling.

Researchers have studied many factors that influence how children develop. A large study of 1,386 children aged three to seven took place across four locations. These included Michigan State University, Oregon State University, the University of Michigan, and the Texas Health Science Center at Houston. The study looked at self-regulation, which is a way of functioning that helps people reach future goals. Researchers found that gender, language, and a mother's education level all play roles. Other factors, such as poverty or a single-parent household, are also linked to behavior.

Learning in early childhood is a holistic process. Children do not learn social, physical, or language skills in isolation. Instead, they learn through entire experiences. The most intense period of learning occurs between birth and age three. During this window, the brain grows so quickly that parts can nearly double in one year. To support this, children need vital nutrients and mental stimulation. While adults provide much of this care, children also learn deeply through interaction with their peers. These early friendships help build social connections that last for life.
