3.6 Social-Emotional Development

Example of Overgeneralization: Two-year-old Jia uses "sweeped" instead of "swept". This reflects children’s tendency to apply grammatical rules incorrectly, known as overgeneralization.
Key Concepts in Language Acquisition:
- Operant Conditioning: Learning through reinforcement and punishment.
- Modeling: Children imitate the language used by adults.
- Overgeneralization: Applying regular grammar rules incorrectly (e.g. "goose" to "gooses").

Comparison Between Age Groups: A 40-year-old man vs. his 7-year-old son learning a new language.
Key Differences:
- The child will have an easier time producing unfamiliar phonemes.
- Adults may learn grammar more slowly but eventually acquire it better due to experience.

Developmental Milestone: By age six months, infants can distinguish phonemic differences.
Cross-Cultural Study Findings:
- Japanese infants do not distinguish between certain sounds that are not present in their language by age 12 months.
Key Term Studied: Phoneme - the smallest unit of sound in a language.

Theory Overview: Child development is influenced by a series of nested social systems.
Systems Defined:
- Microsystem: Immediate environments (family, school).
- Mesosystem: Interactions between microsystems (e.g. parent-teacher relationships).
- Exosystem: Indirect environments (workplaces, mass media).
- Macrosystem: Wider societal and cultural values.
- Chronosystem: Changes over time affecting development (historical events, life transitions).

Types of Parenting Styles:
- Authoritarian: High demands, low emotional support.
- Authoritative: High demands and high emotional support.
- Permissive: Low demands, high emotional support.
Impact on Development: Authoritative parentings are linked with the development of self-reliance and confidence in children.

Attachment Bond: Emotional connection between caregiver and child, influencing later relationships.
Types of Attachment Styles:
- Secure: Trusting relationships, leads to healthier adult relationships.
- Insecure Avoidant: Detached and unconcerned about separation.
- Anxious/Preoccupied: Anxious or clingy behaviors.
- Disorganized: Inconsistent behaviors during separation.

Overview of Stages:
- Trust vs. Mistrust: Infants learn if the world is safe or unpredictable.
- Autonomy vs. Shame: Toddlers learn independence or doubt their abilities.
- Initiative vs. Guilt: Preschoolers learn to initiate tasks.
- Industry vs. Inferiority: Early school years, comparison against peers.
- Identity vs. Role Confusion: Adolescents explore and refine their personal identities.
- Intimacy vs. Isolation: Young adults form intimate relationships.
- Generativity vs. Stagnation: Middle-aged individuals consider contributions to society.
- Integrity vs. Despair: Reflection on life quality during late adulthood.

Definition: Potentially traumatic events occurring before age 18, leading to long-term effects on health and development.
Types of ACEs: Physical, emotional abuse, household dysfunction, neglect.
Impact of ACEs: Correlated with a higher risk of mental and physical health issues later in life, emphasizing the importance of protective factors such as stable relationships and supportive environments.
