Cognitive Development Stages

Cognitive Development

• Refers to the process by which children acquire, process, and use knowledge to adapt to their environment
• Key theorists:
  • Jean Piaget: proposed that children progress through four stages of cognitive development, each characterized by a unique way of thinking and understanding the world
  • Lev Vygotsky: emphasized the role of social interaction and culture in shaping cognitive development
• Stages of cognitive development:
  1. Sensorimotor (0-2 years): infants learn through sensory experiences and motor activities
  2. Preoperational (2-7 years): children develop symbolic thinking and use language to represent the world
  3. Concrete operational (7-11 years): children can think logically and solve problems using concrete objects
  4. Formal operational (11-15 years): adolescents develop abstract thinking and can reason logically about abstract concepts

Social-emotional Development

• Refers to the process by which children develop emotional regulation, empathy, and social skills
• Key theorists:
  • Erik Erikson: proposed that children progress through eight stages of psychosocial development, each characterized by a unique social-emotional challenge
  • Urie Bronfenbrenner: emphasized the role of the environment and social relationships in shaping social-emotional development
• Stages of social-emotional development:
  1. Trust vs. Mistrust (0-1 year): infants develop a sense of trust or mistrust based on caregiver responsiveness
  2. Autonomy vs. Shame and Doubt (1-3 years): children develop a sense of independence and self-control
  3. Initiative vs. Guilt (3-6 years): children take on more responsibility and develop a sense of purpose
  4. Industry vs. Inferiority (6-12 years): children develop a sense of competence and self-worth

Language Development

• Refers to the process by which children acquire language and communication skills
• Key theorists:
  • Noam Chomsky: proposed that children are born with an innate ability to acquire language
  • B.F. Skinner: emphasized the role of environmental factors and reinforcement in shaping language development
• Stages of language development:
  1. Babbling (6-9 months): infants make cooing sounds and experiment with vocalizations
  2. Holophrastic stage (9-12 months): infants use single words to communicate
  3. Telegraphic stage (12-18 months): children use short sentences and omit grammatical markers
  4. Early sentence stage (18-24 months): children use simple sentences and begin to understand grammar

Moral Development

• Refers to the process by which children develop moral principles and values
• Key theorists:
  • Lawrence Kohlberg: proposed that children progress through six stages of moral development, each characterized by a unique moral perspective
  • Carol Gilligan: emphasized the role of care and empathy in shaping moral development
• Stages of moral development:
  1. Obedience and punishment (pre-conventional): children obey rules to avoid punishment
  2. Instrumental relativism (pre-conventional): children pursue their own interests and ignore rules
  3. Interpersonal concordance (conventional): children conform to social norms and expectations
  4. Social contract (post-conventional): children develop a sense of moral principles and justify their actions

Attachment Theory

• Refers to the process by which children form emotional bonds with caregivers
• Key theorists:
  • John Bowlby: proposed that children's attachment styles are shaped by their early relationships with caregivers
  • Mary Ainsworth: developed the "strange situation" test to assess attachment security
• Types of attachment:
  • Secure: children feel comfortable and secure in their relationships
  • Anxious-ambivalent: children are anxious and uncertain in their relationships
  • Avoidant: children avoid intimacy and emotional connection
  • Disorganized-disoriented: children exhibit a mix of anxious and avoidant behaviors

Psychoanalytic Theory

• Refers to the theory that children's behavior and development are influenced by unconscious thoughts, feelings, and memories
• Key theorists:
  • Sigmund Freud: proposed that children's development is shaped by the interaction between the id, ego, and superego
  • Erik Erikson: applied psychoanalytic theory to the study of child development and proposed the eight stages of psychosocial development
• Concepts:
  • Id: the primitive, instinctual part of the personality
  • Ego: the rational, logical part of the personality
  • Superego: the moral component of the personality
  • Defense mechanisms: unconscious strategies used to cope with stress and anxiety
