Child Development Overview

GENERAL PHYSICAL DEVELOPMENT

• Arms and legs grow more rapidly than the torso, leading to a lanky appearance.
• Growth rate slows compared to preschool and adolescence; better healthcare and nutrition contribute to increased size.
• BRAIN reaches nearly adult size, with significant development in the FRONTAL LOBES influencing judgment, impulse control, emotions, and problem-solving.
• RESPIRATORY SYSTEM becomes more efficient, with deeper and slower breathing as lung elasticity improves.
• CIRCULATORY SYSTEM development is slower; heart size increases fivefold since birth.
• PERMANENT TEETH replace milk teeth, with malocclusion being a common issue requiring braces for correction.
• Approximately 20% of children have vision problems, with MYOPIA being the most prevalent, impacting academic performance.
• Individual growth rates vary with potential pauses in growth, still maintaining average height standards.
• Growth patterns differ by gender; from ages 10 to 11, girls typically grow faster in height and weight than boys.
• Factors influencing physical development include race, nationality, and socioeconomic status, with significant height differences among children from various regions.
• Genetic and environmental factors both play roles in physical growth; children from areas with low malnutrition and disease are often taller.
• Sleep significantly influences growth, as a growth hormone is primarily secreted during deep sleep; inadequate sleep can affect growth, appetite, and cognitive function.
• Poor sleep quality is linked to obesity, depression, anxiety, and low self-esteem in children.

MOTOR SKILLS

• Increased strength, coordination, and muscular control lead to the development of new motor skills.
• Improvements in balance and physical movement create elegance in movement.
• Children can achieve skill levels comparable to adults but may lack speed, strength, and stamina.
• Gross motor skills tend to develop more rapidly in boys, attributed to greater muscle mass.
• Social and cultural factors also influence motor skill development and gender roles.
• Development of motor skills positively impacts personality facets and cognitive abilities, enabling skills such as writing, drawing, painting, and music.
• Participation in individual and team sports fosters social development, rule-following, and teamwork.
• Athletic ability can enhance popularity among peers, boosting self-esteem for skilled children.

SEXUALITY

• Common misconception views middle childhood as a latency period with minimal sexual interest; this is known as SEXUAL LATENCY.
• Current understanding acknowledges ongoing sexual development during this stage, countering earlier beliefs.
