Semester 2 psychology: Developmental psychology - Prenatal until preschool Flashcards
Prenatal until preschool
What are the various developmental stages:
Prenatal Development
Early and Middle Childhood
Adolescence
Adulthood
Explain conception in the germinal stage
When a single sperm cell successfully
penetrates the ovum (egg), uniting their genetic material to create a unique zygote.
This marks the beginning of a new life.
Explain cell division in the germinal stage
The process is called cleavage. The zygote divides into a cluster of cells known as a morula, which then forms a hollow ball of cells called a blastocyst.
Explain implantation in the germinal stage
During implantation, the blastocyst embeds itself into the thickened lining of the uterus (the endometrium). This process establishes the foundation for the developing embryo and placenta and begins complex interactions between the mother and offspring.
How does genetic Disorders affect prenatal development?
Inherited genetic mutations or chromosomal abnormalities can lead to congenital disorders, such as Down syndrome, cystic fibrosis, or sickle cell disease, impacting the fetus’s physical, cognitive, and developmental aspects.
How does maternal nutrition affect prenatal development?
Adequate maternal nutrition is crucial for the proper growth and development of the fetus. Deficiencies in essential nutrients like folic acid, iron, or iodine can increase the risk of neural tube defects, anemia, or impaired brain development. Additionally, maternal obesity or malnutrition can negatively impact fetal growth and development.
How can high levels of maternal stress affect the developing fetus?
High levels of maternal stress—whether physical, emotional, or psychological—can trigger the release of stress hormones like cortisol, which may disrupt fetal brain development and increase the risk of preterm birth or low birth weight. Chronic stress during pregnancy is also linked to developmental delays, behavioral issues, and cognitive impairments in the child.
How do the cultural, socioeconomic, and family environments affect prenatal development?
The cultural, socioeconomic, and family environments significantly influence prenatal development. Access to quality healthcare, educational resources, and supportive social networks can positively impact fetal growth and development. In contrast, poverty, discrimination, or exposure to environmental toxins can have detrimental effects on the developing fetus.
What are the potential effects of using recreational drugs, alcohol, or certain prescription medications during pregnancy?
The use of recreational drugs, alcohol, or certain prescription medications during pregnancy can lead to serious consequences for the developing fetus, including birth defects, growth restrictions, preterm birth, and various developmental and behavioral issues in the child.
hat is the neonatal period, and why is it significant?
The neonatal period covers the first 28 days of life, a crucial time when the newborn makes rapid physiological and behavioral adjustments from the uterine environment to independent life.
Explain the establishment of respiration during the Neonatal period.
The new-born’s lungs inflate for the first time, and the circulatory system undergoes significant changes.
Explain the Thermoregulation during the Neonatal Period
The new-born must adapt to external temperatures and
maintain a stable body temperature.
Explain the Digestive system during the Neonatal Period
The new-born’s digestive system adjusts to oral feeding and
the breakdown of nutrients.
Explain sensory development: Vision.
Initially blurry, vision gradually improves over the first few weeks.
Explain sensory development: Hearing
New-borns respond to sounds, particularly high-pitched voices
