Chapter 11: Physical and Cognitive Development in Adolescence 1. Conceptions of Adolescence: ○ Adolescence as a transitional period between childhood and adulthood. ○ Social and psychological changes mark it as distinct from both childhood and adulthood. 2. Puberty: ○ Hormonal Changes: Increase in sex hormones (estrogen, testosterone), triggering physical changes. ○ Growth Spurts: Rapid increases in height and weight; females generally start earlier than males. ○ Motor Development: Improved physical strength, speed, and coordination. ○ Sexual Maturation: Primary Sexual Characteristics: Development of reproductive organs (ovaries, testes). Secondary Sexual Characteristics: Visible changes (breast development, voice deepening, body hair). Menarche (first menstrual period in females) and Spermarche (first ejaculation in males). ○ Secular Trend: Shift toward earlier puberty onset over recent generations, possibly due to nutrition and health factors. 3. Adolescent Brain Development: ○ Changes in the prefrontal cortex (planning, impulse control) and limbic system (emotional responses). ○ Synaptic pruning and myelination improve processing speed but leave room for risk-taking. 4. Eating Disorders: ○ Anorexia Nervosa: Self-starvation, extreme fear of gaining weight. ○ Bulimia Nervosa: Binge eating followed by purging. ○ Causes include social pressure, genetics, and psychological factors. 5. Sexual Health: ○ STIs: Adolescents are at high risk for STIs due to lack of protection or education. ○ Teen Pregnancy: Risks include lack of prenatal care, socioeconomic challenges. 6. Piaget’s Formal Operations: ○ Hypothetical-Deductive Reasoning: Ability to develop hypotheses and test them systematically. ○ Propositional Thought: Logical reasoning about hypothetical or abstract propositions. ○ Adolescent Egocentrism: Imaginary audience (self-consciousness) and personal fable (belief in uniqueness and invulnerability). 7.

Chapter 11: Emotional and Social Development in Adolescence Key Concepts: 1. Adolescent Developmental Period: ○ Adolescence spans from approximately ages 12–18, marked by rapid physical, cognitive, and emotional changes. 2. Emotional Development: ○ Adolescents experience heightened emotional intensity due to hormonal changes and the development of the limbic system (emotion regulation). ○ Emotional Self-Regulation: Development of the ability to manage intense emotions, such as anger or frustration, increases with age. ○ Identity and Self-Esteem: Adolescents are exploring their identities and roles, which can lead to fluctuations in self-esteem and emotional well-being. ○ Parent-Child Relationships: As adolescents seek independence, relationships with parents may become more conflictual but are crucial for emotional development. 3. Social Development: ○ Peer Relationships: Friendships become more intimate, and peer acceptance is a significant factor in self-esteem. Peer pressure can influence behavior, both positively and negatively. ○ Romantic Relationships: Romantic involvement can play an important role in adolescent emotional growth. Adolescents explore different attachment styles and emotional intimacy. ○ Cultural and Gender Influences: Cultural context can shape how adolescents experience and express emotions. Gender differences may impact the way adolescents handle emotions and relationships. 4. Erikson’s Psychosocial Theory: ○ Identity vs. Role Confusion: Adolescents struggle to form a coherent sense of identity, influenced by experimentation with different roles, behaviors, and values. ○ Social Comparison: Adolescents evaluate themselves against peers to form their identity and self-concept. 5. Identity Statuses (James Marcia): ○ Identity Achievement: Commitment to values, beliefs, and goals following exploration. ○ Identity Moratorium: Exploration without commitment. ○ Identity Foreclosure: Commitment without exploration.  ○ Identity Diffusion: No exploration or commitment. Chapter 12: Physical and Cognitive Development in Adolescence Key Concepts: 1. Physical Development: ○ Puberty: Puberty marks the transition from childhood to adolescence, characterized by hormonal changes and the development of secondary sexual characteristics. Early vs. Late Puberty: Early maturation can result in both advantages and challenges for adolescents, including greater attention from peers but also higher risk for mental health issues. ○ Sexual Maturation: The development of sexual characteristics (e.g., menarche in girls and spermarche in boys) leads to sexual identity formation. 2. Cognitive Development: ○ Piaget’s Formal Operational Stage: Adolescents develop the ability to think abstractly, reason logically, and plan systematically. ○ Hypothetico-Deductive Reasoning: The ability to think through a problem systematically, considering multiple possibilities. ○ Adolescent Egocentrism: The belief that others are preoccupied with one’s own behavior, leading to the imaginary audience (feeling as though one is constantly being observed) and personal fable (belief in one’s uniqueness and invulnerability). 3. Decision-Making and Risk-Taking: ○ Adolescents are more likely to engage in risky behaviors due to underdeveloped prefrontal cortex (responsible for impulse control and reasoning) and the influence of peer dynamics. ○ Adolescent Brain Development: Changes in the brain, particularly in the prefrontal cortex, contribute to increased impulsivity and risk-taking behavior. 4. School and Achievement: ○ Academic Performance: Adolescents’ motivation, self-esteem, and cognitive abilities strongly influence academic performance. School engagement is tied to identity formation and future success. ○ Influences of Socioeconomic Status: SES can influence the opportunities available to adolescents, impacting academic achievement and cognitive development. Chapter 13: Emotional and Social Development in Emerging Adulthood Key Concepts: 1. Emerging Adulthood (18–25 years): ○ This developmental stage represents the transition from adolescence to full adulthood, marked by exploration of identity, instability, self-focus, and a feeling of being "in-between." 2. Intimacy vs. Isolation (Erikson): ○ Intimacy: The ability to form deep, committed relationships with others is crucial in early adulthood. ○ Isolation: The inability to connect with others emotionally, which can lead to loneliness and difficulty with long-term relationships. 3. Cognitive Development: ○ Postformal Thought: Reflective, relativistic thinking emerges, allowing individuals to view problems in more complex ways, understanding that there are often multiple solutions to issues. ○ Cognitive Flexibility: Increased ability to switch between different ideas and viewpoints. 4. Social and Emotional Relationships: ○ Friendships and Romantic Relationships: These are central to the development of intimacy in adulthood. Romantic relationships and marriage offer both support and challenges. ○ Parenthood: The transition to becoming a parent can influence identity and emotional development. 5. Career Development: ○ Emerging adults often go through a series of career explorations and changes before settling into a stable job. ○ Vocational Identity: The development of a clear sense of career and work role is a key part of emerging adulthood. Chapter 14: Physical and Cognitive Development in Middle Adulthood Key Concepts: 1. Physical Development:  ○ Changes in Physical Health: Middle adulthood (ages 40–65) is marked by gradual changes in physical health, including slower metabolism, reduced muscle mass, and changes in vision and hearing. ○ Menopause and Andropause: For women, menopause marks the end of reproductive ability, while men may experience reduced testosterone levels. ○ Chronic Illnesses: Common health issues like hypertension, arthritis, and heart disease often arise during this stage. 2. Cognitive Development: ○ Fluid vs. Crystallized Intelligence: Fluid intelligence (problem-solving and reasoning) declines with age, while crystallized intelligence (knowledge and experience) remains stable or increases. ○ Memory Changes: There is often a decline in memory performance in middle adulthood, but strategies like experience and organization can offset some of the cognitive decline. 3. Career and Work: ○ Midlife Career Transition: Individuals often reevaluate their careers and may make changes, such as switching professions, taking on new roles, or pursuing passions. ○ Generativity vs. Stagnation (Erikson): The desire to contribute to the next generation, either through work, family, or social causes, is central in middle adulthood. 4. Social Development: ○ Empty Nest Syndrome: Parents experience psychological adjustment when children leave home. ○ Friendships and Social Networks: Social relationships become increasingly important for emotional well-being in middle adulthood. Chapter 15: Emotional and Social Development in Late Adulthood Key Concepts: 1. Late Adulthood (65+ years): ○ This stage involves physical and cognitive decline, but also a focus on reflection, meaning-making, and social connectedness. 2. Erikson’s Integrity vs. Despair: ○ Integrity: The ability to look back on life with a sense of satisfaction. ○ Despair: A sense of regret and dissatisfaction with one's life achievements. 3. Physical and Cognitive Aging: ○ Physical Decline: Reduced mobility, sensory changes, and chronic conditions become more prominent.  ○ Cognitive Decline: Some cognitive functions, such as processing speed and memory, may decline, but others, like wisdom and life experience, may remain intact. 4. Social Relationships in Late Adulthood: ○ Social Support Networks: Relationships with family, friends, and caregivers are crucial for emotional well-being. ○ Grandparenthood: Becoming a grandparent can enhance feelings of generativity and social connectedness. 5. Living Arrangements and Long-Term Care: ○ Decisions around living independently, in assisted living, or with family members affect quality of life in late adulthood. Chapter 16: Death and Dying Key Concepts: 1. Theoretical Models of Dying: ○ Kubler-Ross’s Five Stages of Grief: Denial, Anger, Bargaining, Depression, and Acceptance. ○ Individual Differences in Dying: Not everyone experiences these stages in the same order, and some may skip stages entirely. 2. End-of-Life Care: ○ Hospice Care: Focused on improving quality of life for terminally ill patients by managing symptoms rather than curing the illness. ○ Palliative Care: Comfort care that focuses on relieving pain and improving the quality of life for those nearing death. 3. Grief and Bereavement: ○ Grief Process: Grieving is a highly individual process that can involve shock, sadness, and anger. ○ Complicated Grief: Prolonged and intense grief that interferes with normal functioning. 4.
