A legal document outlining an individual's preferences for future medical or mental health treatment. It may also include a health care proxy.

Living Will

A legal written document used as a tool that allows individuals to outline their preferences and instructions for future healthcare in case they become incapable of making decisions themselves. 

Advance Directive

Refers to the sorrow felt after a major loss, such as the death of a loved one. Severe grief can become life-threatening by weakening the immune system, leading to self-neglect, and causing suicidal thoughts.

Grief

Sudden Infant Death Syndrome (SIDS) is a condition where an infant dies unexpectedly during sleep after ceasing to breathe. The highest risk is observed in infants under one year old, with a higher incidence in boys. Several risk factors are associated with SIDS, such as premature birth, exposure to smoke in the household, and hyperthermia (overheating). Additionally, studies suggest that infants who succumb to SIDS may have underlying differences in brain structure and function.

Coping refers to the conscious, deliberate, and purposeful regulation of emotions, especially in situations perceived as threatening or stressful.

Coping

The implementation of end-of-life directives, including living wills and Do Not Resuscitate (DNR) orders, along with the provision of hospice care, raises significant ethical, legal, and practical challenges. These issues often involve debates over patient autonomy, the potential for misinterpretation of a patient's wishes, conflicts between family members and healthcare providers, and the emotional burden placed on all parties involved.

Critiques of End-of-Life Directives and Care

How death is viewed is heavily influenced by one's cultural and personal background. Some cultures embrace death as a natural part of life. In contrast, the historical approach in the United States, until about 50 years ago, often involved dying in a hospital without being explicitly informed of one's terminal condition.

Cultural Perspectives on Death

Hospice care is a program designed to provide a dignified death for terminally ill individuals, focusing on pain management and comfort in a humane setting, often at home rather than in a hospital. The modern hospice movement was initiated by Cicely Saunders in England in 1967, and the first hospice in the United States was founded by Florence Wald in 1974. Currently, hospice care serves approximately 1.65 million Americans and their families, enabling many to spend their final days in a familiar environment.

Hospice Care

A psychologist who collaborated with the pioneers of hospice care and introduced the influential five-stage model of grief to explain the process of an individual accepting their own mortality.

Elizabeth Kübler-Ross

Death is the final event in the human lifespan, signifying the conclusion of an individual's life.

Death as the Endpoint of the Lifespan

The five-stage model of grief, developed by Elisabeth Kübler-Ross, is a theoretical framework used to explain the psychological process individuals may experience when confronting death.

This refers to the idea that families and parental relationships with children can have a lasting impact on adolescent development due to these often being the first interactions a child experiences in life. 

Family Influences

Language development refers to the process by which humans come to understand and communicate language. This field of study examines the stages of language acquisition from infancy through adulthood, including the development of phonology, morphology, syntax, semantics, and pragmatics.

Language Development

Cognitive development refers to the changes in an individual's mental processes. This domain includes the development of learning, attention, memory, language abilities, thinking, reasoning skills, and creativity.

Cognitive Development

The process of finding or categorizing one's own identity within or outside of the gender binary. This involves multiple factors, including consolidating one's identity with one's biological sex, one's role in the immediate microsystem, or even the stereotypes one faces. This process often occurs in childhood through adolescence, but can be a lifelong journey.

Gender Development

Death-Related Topics in Psychology

Attachment is defined as a long-standing connection or bond with others. In the context of developmental psychology, it specifically refers to the crucial bond formed between an infant and a caregiver, which is considered the major social milestone of infancy. The study of attachment also extends to adulthood, examining the tendency to seek and maintain emotionally supportive relationships.

Attachment in Developmental Psychology

The normative approach in developmental psychology seeks to understand and define "normal" development by establishing norms, or average ages, for achieving specific developmental milestones. Originating in the early 20th century, this method involves studying large groups of children across various ages to determine these benchmarks. These norms are applied across the three developmental domains (physical, cognitive, and psychosocial) and are used by psychologists as general guidelines to identify when a child might need additional support. However, there is a contemporary awareness that the term "normal" should be used with consideration, with some practitioners preferring alternative terminology.

Normative Approach to Development

From infancy to childhood, individuals develop:
- Reflexes
- Motor Skills

Physical Development from Infancy to Childhood

The contrast between a newborn sea turtle's instinctual journey to the ocean and a human learning to surf or swim illustrates the difference between innate and learned behaviors. Sea turtles are born with the knowledge to find the ocean and swim without parental guidance. In contrast, humans are not born with complex skills like swimming or surfing; these abilities must be acquired through practice, observation, and instruction.

Developmental psychology grapples with several fundamental questions about human growth. Three of the most significant debates are: 1) Continuity vs. Discontinuity, which questions if development is a smooth, gradual process or occurs in distinct stages; 2) One Course vs. Many Courses, which explores whether development follows a universal path for all individuals or varies based on unique sociocultural contexts; and 3) Nature vs. Nurture, which examines the interplay between genetic inheritance and environmental influences in shaping development.

Major Issues in Developmental Psychology

The nature versus nurture debate is a foundational question in psychology that investigates the relative influence of genetics and biology (nature) versus environment and culture (nurture) in shaping an individual. This debate explores how our personalities and traits are determined by our genetic inheritance and biological factors, and how they are molded by our surroundings, including our family, peers, and cultural context. The core of this debate is captured by questions such as why children often resemble their biological parents, whether adopted children are more similar to their biological or adoptive families, and what accounts for the differences between siblings raised in the same household.

The Nature vs. Nurture Debate in Developmental Psychology

To study the human lifespan, developmental psychologists often segment it into distinct, age-based periods. This approach, which is similar to the structure of theories like Erikson's, allows for a focused examination of development. The primary stages include prenatal development, infancy, childhood, adolescence, and adulthood.

Age-Based Stages of Lifespan Development

Two developmental psychologists are observing a child's progress in learning to walk. Psychologist A argues, 'The child's ability is improving bit by bit each day; yesterday they could barely stand, and today they took a wobbly step. It's a slow, steady process.' Psychologist B counters, 'I disagree. The child is not just getting 'better' at standing. They have now moved into a completely new phase of mobility, which is fundamentally different from the crawling phase.' What is the fundamental disagreement between these two psychologists?

Theories of social development provide theoretical frameworks for understanding how individuals develop social and emotional skills, form attachments, and interact with their environments over time. The primary perspectives include psychoanalytic theories, learning theories, theories of social cognition, and ecological theories of development.
