Unit 3 AP PYSCH- Developmental

Developmental Psychology

What are the fundamental differences between continuous and discontinuous development?

Continuous development suggests that growth happens gradually and steadily over time, like a tree slowly growing taller. Discontinuous development, on the other hand, proposes that development occurs in distinct stages, with sudden leaps forward, similar to a caterpillar transforming into a butterfly.

How do Piaget's stages of cognitive development explain changes in thinking throughout childhood?

Jean Piaget proposed four stages:

  • Sensorimotor (birth-2 years): Infants learn through senses and motor actions. They develop object permanence, understanding objects exist even when unseen.

  • Preoperational (2-7 years): Children use symbols and language but struggle with logic. They exhibit egocentrism, difficulty seeing others' perspectives.

  • Concrete Operational (7-11 years): Logical thinking develops, but abstract thought is limited. Children grasp conservation, understanding quantity remains constant despite changes in appearance.

  • Formal Operational (12+ years): Abstract and hypothetical thinking emerge, enabling complex reasoning and problem-solving.

What is Vygotsky's Zone of Proximal Development, and how does scaffolding support learning?

The Zone of Proximal Development (ZPD) is the gap between what a child can do independently and what they can achieve with guidance. Scaffolding is the support provided by a more knowledgeable person, like a teacher or parent, to help the child learn within their ZPD. This support gradually decreases as the child's competence grows.

What are the key milestones in language development during infancy and early childhood?

  • Babbling Stage (4 months): Infants experiment with sounds, producing a wide range of babbles unrelated to their native language.

  • One-Word Stage (1-2 years): Children begin using single words to express desires and label objects.

  • Telegraphic Speech (2+ years): Two-word phrases emerge, resembling telegrams with essential nouns and verbs, like "go car".

  • Overgeneralization: Children apply grammatical rules too broadly, such as saying "goed" instead of "went."

How does secure attachment in infancy influence social and emotional development later in life?

  • Secure attachment, fostered by responsive and consistent caregiving, provides a foundation for healthy social and emotional development. Securely attached individuals tend to:

  • Form trusting and stable relationships: They feel safe and secure in close relationships, allowing for open communication and emotional intimacy.

  • Thrive in relationships: They do not fear being alone but generally enjoy and benefit from close, meaningful connections.

  • Set healthy boundaries: They can establish appropriate boundaries, respecting their own needs and the needs of others.

What are the characteristics of authoritarian, permissive, and authoritative parenting styles, and how do they impact children?

  • Authoritarian: High demands, low responsiveness. Strict rules, harsh punishments, limited communication. Children may be obedient but less happy and socially competent.

  • Permissive: Low demands, high responsiveness. Few rules, indulgent, avoids confrontation. Children may lack self-discipline and have difficulty with authority.

  • Authoritative: High demands, high responsiveness. Clear expectations, supportive, encourages independence. Children tend to be well-adjusted, happy, and successful.

How do Erik Erikson's stages of psychosocial development explain the challenges individuals face throughout their lives?

Erikson proposed eight stages, each with a psychosocial crisis to resolve:

  • Trust vs. Mistrust (infancy): Developing a sense of trust in caregivers and the world.

  • Autonomy vs. Shame and Doubt (toddlerhood): Gaining independence and self-sufficiency.

  • Initiative vs. Guilt (preschool): Taking initiative, exploring, and developing a sense of purpose.

  • Industry vs. Inferiority (elementary school): Mastering skills and feeling competent.

  • Identity vs. Role Confusion (adolescence): Forming a strong sense of self and identity.

  • Intimacy vs. Isolation (young adulthood): Developing close, loving relationships.

  • Generativity vs. Stagnation (middle adulthood): Contributing to society and leaving a legacy.

  • Integrity vs. Despair (late adulthood): Reflecting on life with a sense of fulfillment.

What are Adverse Childhood Experiences (ACEs), and how can they impact individuals later in life?

ACEs are traumatic events experienced during childhood, such as abuse, neglect, or household dysfunction. They can have long-term negative impacts on:

  • Physical health: Increased risk of chronic diseases like heart disease, diabetes, and cancer.

  • Mental health: Higher likelihood of depression, anxiety, PTSD, and substance abuse.

  • Social and behavioral problems: Difficulty forming relationships, lower educational attainment, and increased risk of criminal behavior.




Enduring Themes in Developmental Psychology

  • Stability and Change: This theme explores which traits remain consistent and which are subject to change throughout life.

  • Continuous and Discontinuous Stages of Development: This debate centers around whether development happens gradually or in distinct stages.

  • Nature and Nurture: This examines the relative influence of genetics (nature) versus environment and experience (nurture) on development.

Research Design Methods

  • Longitudinal Study: This method follows a person or group over a long period to observe developmental changes.

  • Cross-sectional Study: This method compares individuals of different ages at a single point in time.

Physical Development Across the Lifespan

Prenatal Development:

  • Teratogens: Exposure to harmful substances (e.g., alcohol, drugs, viruses) during pregnancy can impact fetal development.

  • Maternal Illness: Illnesses contracted by the mother can be transmitted to the newborn.

  • Genetic Mutation: Changes in genetic material can lead to developmental variations.

Infancy and Childhood:

  • Developmental Norms: These provide a general timeline for expected physical and mental growth.

  • Reflexes: Infants are born with automatic responses like the rooting reflex.

  • Visual Cliff: This experiment tests depth perception in infants.

  • Critical Period: Specific time windows in early life where certain stimuli or experiences are crucial for normal development.

  • Imprinting: Observed in some animals, this is a rapid and strong attachment formed during a critical period.

Adolescence:

  • Puberty: This period marks the physical beginnings of sexual maturity.

  • Primary Sex Characteristics: Organs necessary for reproduction.

  • Secondary Sex Characteristics: Non-reproductive traits that develop during puberty.

  • Menarche: A female's first menstrual period.

  • Spermarche: A male's first ejaculation.

Adulthood:

  • Physical Changes: Adulthood sees a gradual decline in reproductive ability, mobility, flexibility, reaction time, and sensory acuity.

  • Menopause: The cessation of menstrual cycles in women.

Gender and Sexual Orientation

  • Sex: Biological categorization as male or female.

  • Gender: Socially constructed roles, behaviors, expressions, and identities associated with being male, female, or other gender identities.

Cognitive Development Across the Lifespan

Jean Piaget's Theory:

  • Four Stages of Cognitive Development:

    • Sensorimotor (birth to 2 years): Object permanence develops.

    • Preoperational (2 to 7 years): Characterized by egocentrism and symbolic thought.

    • Concrete Operational (7 to 11 years): Logical reasoning and conservation develop.

    • Formal Operational (12 years and up): Abstract and hypothetical thinking emerges.
