Biosocial Development This domain refers to the physical and biological changes such as motor skills, brain development, puberty, and health management. 1. Early Childhood (2-6 years) Myelination: The process of insulating neurons to increase brain efficiency. This boosts motor skill development. Corpus Callosum Development: Connects the two hemispheres of the brain, improving coordination and complex thinking. Injury Control & Prevention: Children explore their environment, increasing the risk of accidents. Caregivers focus on safety education. Toilet Training: A key milestone where children learn self-care, marking growing independence. Parenting Styles: Different styles (authoritative, authoritarian, permissive) influence children's physical and emotional growth. 2. Middle Childhood (7-11 years) Childhood Obesity: Diet and activity patterns stabilize, but poor habits can lead to weight issues. Health education is essential. Structured Sports Participation: Children engage in physical activities, helping improve motor coordination and teamwork skills. Injury Prevention: Sports and recreational activities bring a need for safety education. Puberty Preparation: Though most children won’t experience puberty yet, subtle hormonal shifts can begin. 3. Adolescence (12-18 years) Secondary Sex Characteristics: Physical signs of puberty such as voice deepening, breast development, and body hair appear. Menarche & Spermarche: First menstrual period and ejaculation mark reproductive maturation. Risk-Taking Behaviors: Teens tend to engage in risky activities due to a developing prefrontal cortex (decision-making). Eating Disorders: Body image issues may arise, leading to conditions like anorexia or bulimia. Cognitive Development This domain refers to mental skills, including learning, problem-solving, memory, and reasoning. 1. Early Childhood (2-6 years) Symbolic Thought: Children begin to use symbols (e.g., words, images) in pretend play. Egocentrism: They have difficulty understanding other people’s perspectives (a hallmark of Piaget’s preoperational stage). Fast Mapping: Rapid vocabulary learning occurs, helping children communicate effectively. Theory of Mind: Children begin to understand that others have their own thoughts and feelings. 2. Middle Childhood (7-11 years) Concrete Operational Thought: Logical thinking develops, though limited to tangible objects (Piaget’s concrete operational stage). Working Memory Expansion: Increased ability to retain and manipulate information helps with academic tasks. Social Comparison: Children compare themselves to peers, affecting self-esteem and motivation. Bilingualism & ELL Programs: Language skills are refined, and second languages may be learned in structured programs. 3. Adolescence (12-18 years) Formal Operational Thought: Teens begin to think abstractly and hypothetically (Piaget’s formal operational stage). Deductive & Inductive Reasoning: Improved problem-solving abilities allow teens to reason from general principles or specific examples. Imaginary Audience & Personal Fable: Teens feel as if everyone is watching them (imaginary audience) and believe they are unique and invulnerable (personal fable). Moral Reasoning (Kohlberg): Adolescents progress through moral development stages, thinking about justice, fairness, and personal values. Psychosocial Development This domain focuses on emotions, relationships, self-concept, and personality development. 1. Early Childhood (2-6 years)  Initiative vs. Guilt (Erikson): Children learn to initiate activities and take on new challenges. Success builds confidence, while failure can lead to guilt. Intrinsic vs. Extrinsic Motivation: Children become motivated by either internal rewards (fun) or external rewards (praise). Parenting Styles & Sociodramatic Play: Play is critical for emotional regulation and learning social roles. 2. Middle Childhood (7-11 years) Industry vs. Inferiority (Erikson): Success in academic and social activities builds competence, while failure leads to feelings of inferiority. Bullying & Peer Relationships: Friendships deepen, but negative experiences like bullying impact social and emotional health. Resilience Development: Children learn to cope with challenges, building emotional strength. Family Structure & Parenting Practices: Family dynamics and parenting choices continue to shape behavior and school performance. 3. Adolescence (12-18 years) Identity vs. Role Confusion (Erikson): Adolescents explore different roles and beliefs to form their identity. Confusion can lead to uncertainty about their place in society. Peer Pressure & Parental Monitoring: Teens experience increased influence from friends, though parents still play a guiding role. Gender Identity & Sexual Orientation: Adolescents explore and solidify their understanding of these aspects of themselves. Coercive Joining: Teens may join problematic peer groups, leading to risky behaviors and delinquency. Need for Independence: Adolescents seek autonomy, which may cause friction with parents as they assert themselves.
