Study Notes
Human Development Basics
- Focus of human development study centers on change, description, and relationships.
- Life-span studies emphasize the influence of earlier life events on later development.
- Child development gained momentum with child protection laws, scientific discussions, and studies on social contact importance.
Key Concepts in Development
- Qualitative Change: Refers to development characterized by new skills or strategies, like language acquisition or improved memory.
- Quantitative Change: Involves measurable increases, such as weight gain or height growth during development.
Developmental Periods and Influences
- Infancy: Basic needs for food, clothing, and social bonding are crucial.
- Adolescence: Characterized by identity exploration and transition from childhood.
- Young Adulthood: Most individuals complete education, gain independence, and start families.
Social and Environmental Impact
- Socioeconomic status affects development through factors like income, education, and ethnicity.
- Cultural context shapes individual development experiences; children born in different countries will have unique developmental paths.
- Events occurring at typical or atypical times significantly influence life experiences.
Terms to Know
- Normative Influences: Events that affect individuals in similar ways based on age (e.g., starting school).
- Nonnormative Influences: Unusual events impacting personal development.
- Critical Periods: Specific times when certain experiences have heightened effects on development (e.g., language acquisition in early childhood).
Research and Development
- Findings from various studies on aging and child development provide insights into longer-term developmental changes.
- Early strategies influencing development can lead to significant changes later in life.
- Understanding cross-cultural research helps establish norms and recognize cultural impacts on development.
Baltes Principles of Development
- Lifelong Development: Development is a continuous process.
- Historical Context: Development is shaped by the era one lives in.
- Plasticity: Individuals can adapt and change over time in response to experiences.
Conclusion
- Development has numerous interacting factors, including genetic, environmental, and social influences.
- Parenting practices, community resources, and experiences contribute significantly to shaping individual life courses.### Cohorts and Generational Studies
- A generation refers to all members of a cohort sharing similar experiences or historical contexts.
- Cohort differences stem from shared experiences affecting a generation rather than geographical separation or family history.
- Personal cohorts include individuals with whom one shares significant life experiences, such as schoolmates.
Family and Socioeconomic Influences
- In the Oakland Growth Study, factors such as parents' economic stress were found not to significantly impact children's lives during the Great Depression.
- The study indicated that while adolescent children experienced developmental difficulties, alcohol use by fathers during this time remained negligible.
Genetics and Reproductive Biology
- A zygote forms when a sperm and an egg unite, officially termed fertilization.
- Ovulation is the process of releasing an ovum from the ovary, essential for reproduction.
- The chances of fraternal twins arise from factors like age and ethnicity, with variations among groups, such as African-American women having higher probabilities.
Growth and Development
- The human genome project aimed to map gene expression and provide critical DNA data for medical research.
- Genetic scientists study interactions between environmental influences and genetic predispositions impacting development.
- Chromosomes unrelated to sex are referred to as autosomes, while sex cells are designated gametes, and their fertilized form is known as a zygote.
Heredity and Genetic Traits
- Genetic characteristics can be dominant or recessive, with recessive traits appearing only when two copies are present.
- Polygenic inheritance plays a significant role in complex traits influenced by multiple genes.
- Environmental conditions can lead to mutations in genetic material, altering inherited characteristics.
Genetic Disorders and Health Implications
- Disorders such as Huntington’s disease follow dominant inheritance patterns, whereas conditions like Tay-Sachs and sickle-cell anemia result from multifactorial influences.
- Chromosomal abnormalities such as Klinefelter’s and Turner’s syndromes cause specific health issues based on structural differences in chromosomes.
- Most individuals with Down syndrome function to some extent in society, though they may require varying levels of support throughout life.
Prenatal Development and Differentiation
- Sexual differentiation occurs in embryos during the early weeks of pregnancy, which is more complex than previously understood.
- Traits like albinism can manifest when recessive alleles are present without being expressed in parents.
Birth Defects and Maternal Influence
- Infants may be born with sex-linked disorders predominantly affecting males, as they are typically inherited from carrier mothers.
- Genetic counseling is vital for parents with a history of hereditary conditions to assess risks for future children.### Genetic Concepts and Disorders
- Phenotype refers to observable physical traits influenced by genetics and environment.
- Down Syndrome is often a result of an extra chromosome, leading to moderate-to-severe mental retardation. It can be influenced by increased parental age.
- Turner Syndrome in girls arises from a missing X chromosome. Outcomes may vary depending on whether the X is inherited from the mother or father, demonstrating genetic imprinting.
- Karyotype analysis reveals chromosomal abnormalities often associated with disorders like Down syndrome and Turner syndrome.
Genetic Counseling and Family History
- Families with a history of genetic defects have greater needs for genetic counseling (e.g., those with children who have genetic disorders).
- Adoption studies assess the role of environment versus genetics in traits like intelligence, revealing that both significantly contribute to traits.
Heritability and Environmental Influences
- Heritability estimates the genetic contribution to traits. Traits with high heritability are less affected by environment.
- Niche-picking reflects how individuals may select environments that reinforce their genetic tendencies.
- Canalization describes how certain traits are strongly influenced by genetics and resistant to environmental variations.
Intelligence and Developmental Traits
- Intelligence is influenced by both genetic factors and environmental conditions, with studies showing varying degrees of effects at different ages.
- Traits such as eye color exhibit clear heritability, while complex traits like intelligence show interactions between heredity and environment.
Prenatal Development and Inheritance
- The zygote is the fertilized egg, which undergoes cell division and implants in the uterus during the germinal stage.
- Cephalocaudal development describes growth that occurs from head to toe, affecting physical development in utero.
- Prenatal exposure to substances like alcohol poses risks, particularly during the embryonic stage when major systems develop.
Psychological and Behavioral Traits
- Boldness and shyness in children appear to have both genetic and environmental influences.
- Temperament can be identified early in life, suggesting genetic underpinnings.
Miscellaneous Genetic Insights
- Certain psychopathologies, such as schizophrenia, show high concordance rates in monozygotic twins, indicating a strong genetic component.
- The placenta plays a critical role in pregnancy, but it does not directly affect lactation.
Risks and Health During Pregnancy
- Factors such as maternal age and health can influence the risk of miscarriage or stillbirth.
- Miscarriage is commonly caused by chromosomal abnormalities, emphasizing the importance of genetic health prior to conception.
These notes encapsulate key genetic concepts and their implications for development, health, and counseling related to hereditary traits.
