Study Notes

Development and Learning Concepts

Development is a pattern of change starting at conception and continuing throughout life, involving both growth and decline.
Plasticity refers to the capacity for change in response to experiences throughout the lifespan.
Development is multidimensional, influenced by biological, social, and cultural factors, and involves simultaneous changes across various dimensions.
Contextual factors such as historical, economic, social, and cultural elements play crucial roles in shaping development.
Normative age-graded influences, like puberty and retirement, impact individuals similarly within specific age groups.
Normative history-graded influences affect generations based on common historical events (e.g., the Great Depression, COVID-19).

Objectives of Developmental Psychology

Describe changes in individuals at different ages and how they evolve due to aging.
Explain the causes of developmental changes.
Predict future developmental outcomes for individuals.
Intervene and utilize knowledge to enhance individual life quality.

Lifespan Perspective Characteristics

Development is lifelong, with no single period dominating.
Development is multidirectional, comprising gains and losses across various dimensions.
Maintenance and regulation of loss become prominent in middle and late adulthood.

Factors Influencing Development

Biological processes encompass physical changes, including genetic inheritance, brain development, and overall health.
Cognitive processes involve thought, intelligence, and language evolution (e.g., vocabulary acquisition, problem-solving).
Socioemotional processes pertain to relationships, emotions, and personality development.

Contemporary Issues in Development

Health and well-being are heavily influenced by lifestyle choices and psychological factors.
Parenting and education are crucial considerations for child development.
Technology impacts developmental processes and societal behaviors.

Theoretical Frameworks

Psychoanalytical theories focus on unconscious factors and emotional development, notably Freud's psychosexual theory and Erikson's psychosocial stages.
Behavioral and social cognitive theories emphasize the role of environment and cognition in behavioral changes (Skinner, Bandura).
Cognitive theories explore the stages of cognitive development and processes like organization and adaptation (Piaget, Vygotsky).
Ethological theory connects behavior with biological influences and evolution, recognizing sensitive periods in development.

Research Methods in Developmental Psychology

Employ various research designs including case studies, correlational studies, and experiments.
Longitudinal research examines changes over time, while cross-sectional studies compare different age groups.
Cohort effects can influence findings, necessitating designs like accelerated longitudinal studies to better understand developmental trajectories.

Research Ethics

Ethical considerations in developmental psychology research encompass confidentiality, informed consent, and minimizing harm to participants.### Germinal Period
Occurs in the first two weeks after conception.
Involves creation of the zygote, continued cell division, and attachment to the uterine wall.
Epigenetic View emphasizes bidirectional interaction between heredity and environment in development.
Gene x Environment (G x E) Interaction highlights how genetic and environmental factors combine to influence well-being and abilities.

Blastocyst and Trophoblast

Blastocyst: Inner cell layer that develops into the embryo.
Trophoblast: Outer cell layer that provides nutrition and support for the embryo.

Embryonic Period

Occurs from 2 to 8 weeks after conception; rate of cell differentiation significantly increases.
Mass of cells is termed an embryo, consisting of three layers:
- Endoderm: Forms digestive and respiratory systems.
- Mesoderm: Develops muscular, circulatory, reproductive, and excretory systems.
- Ectoderm: Creates nervous system and sensory organs.

Support Systems and Organ Development

Amnion: Fluid-filled sac in which the embryo floats.
Umbilical cord: Contains two arteries and one vein; connects the embryo to the placenta.
Placenta: Disk-shaped tissue facilitating nutrient and waste exchange between mother and embryo.
Organogenesis: Organ formation occurs within the first two months of prenatal development.

Key Developments and Milestones

Detectable fetal heartbeat and limb movement starts at around 12 weeks.
By 12 weeks, the fetus is approximately 3 inches long, weighs about 1 ounce, and can perform reflexive actions like sucking and swallowing.
Distinguishable sex and presence of fingerprints occur by this stage.

Second Trimester Developments

At 16 weeks, the fetus is about 6 inches long and weighs 4 to 7 ounces.
Heartbeat is strong, skin is thin and transparent, and downy hair (lanugo) covers the body.
Fingernails and toenails begin to form, and the fetus exhibits coordinated movements, being able to roll over in amniotic fluid.
