    Study Notes

    The Evolutionary Perspective

    • Natural selection promotes survival and reproduction among the best-adapted individuals of a species.
    • Adaptive behavior enhances an organism's chance of survival in its natural environment.
    • Evolutionary psychology focuses on adaptation, reproduction, and the concept of "survival of the fittest" as fundamental to shaping behavior.
    • Emotional and behavioral traits have emerged with underlying biological potentialities, not strictly dictated by genetics.

    Genetic Foundations of Development

    • Human life initiates from a single cell, with the nucleus containing chromosomes.
    • Gene-linked abnormalities can lead to conditions such as cystic fibrosis, diabetes, hemophilia, Huntington disease, spina bifida, and Tay-Sachs disease.

    Heredity and Environment: Nature vs Nurture Debate

    • Behavior genetics aims to understand how heredity and environment contribute to human traits and development.
    • Twin studies compare behavioral similarities of identical and fraternal twins to assess genetic influence.
    • Adoption studies examine whether adopted children reflect traits of biological or adoptive parents.

    Heredity-Environment Correlations

    • Passive genotype-environment correlation: Biological parents provide a nurturing environment for their genetically related child.
    • Evocative genotype-environment correlation: Children's traits trigger specific environmental reactions.
    • Active or niche-picking genotype-environment correlation: Children seek environments that align with their personal strengths and abilities.

    Epigenetic View and Gene x Environment Interaction

    • Development results from a continuous interplay between heredity and environment, highlighting the bidirectional nature of influence.
    • Gene x environment interaction refers to how specific genetic variations correlate with particular environmental factors.

    Prenatal Development

    • Germinal period lasts from conception to two weeks, leading to zygote formation and attachment to the uterine wall.
    • Embryonic period, occurring from two to eight weeks post-conception, focuses on intense cell differentiation and organogenesis.
    • Fetal period extends from two months after conception to birth, characterized by significant growth and development.

    Prenatal Tests and Reproductive Technology

    • Common prenatal tests include ultrasound sonography, chorionic villus sampling, amniocentesis, maternal blood screening, fetal MRI, and noninvasive prenatal diagnosis (NIPD).
    • Infertility is defined as the inability to conceive after 12 months of unprotected intercourse, often addressed through technologies like in vitro fertilization (IVF).

    Hazards to Prenatal Development

    • Teratogens are agents capable of causing birth defects, impacting cognitive and behavioral outcomes.
    • Psychoactive drugs such as caffeine, alcohol (leading to fetal alcohol spectrum disorders), nicotine, cocaine, methamphetamine, marijuana, and heroin pose significant risks during pregnancy.
    • Other risks include incompatible blood types, environmental hazards, maternal diseases, age, nutrition, and stress levels.

    Prenatal Care

    • Prenatal care varies among women, typically involving scheduled medical visits to monitor manageable conditions and treat diseases affecting mother and baby.
    • Educational, social, and nutritional support services are often included.

    Birth and Postpartum Period

    • The birth process occurs in three stages: dilation of the cervix, delivery of the baby, and expulsion of the placenta.
    • Childbirth assistance varies across cultures, including midwives and doulas who provide support before, during, and after delivery.
    • Medication options for childbirth include analgesia for pain relief, anesthesia for blocking sensations, and oxytocin to induce contractions.
