Infancy & Toddlerhood Flashcards
(48 cards)
What is the cephalocaudal principle vs the proximodistal principle?
With the roximodistal principle, Development starts at the center of the body and moves outward toward the limbs. While, with the cephalocaudal principle, development proceeds from the head downward.
How much do newborns sleep?
Newborns sleep approximately 16-18 hours a day, though not consecutively. (50% of the day)
What is SIDS, and how can it be reduced?
Sudden Infant Death Syndrome, the unexplained death of a seemingly healthy baby during sleep. it can be reduced by placing babies on their backs to sleep, using a firm sleep surface, and keeping the sleep area free of soft bedding.
What is object permanence?
The understanding that objects continue to exist even when they cannot be seen, typically developing around 8-12 months.
What are fine motor skills?
Skills involving small muscle movements, such as grasping and writing.
What are gross motor skills?
Skills involving large muscle movements, such as crawling and walking.
Why is breast milk important for newborns?
It provides essential nutrients and antibodies that help build the baby’s immune system.
What is malnutrition?
A condition resulting from an improper balance of nutrients, leading to health issues.
What is marasmus and kwashiorkor?
Marasmus and kwashiorkor are two distinct forms of severe protein-energy malnutrition (PEM) caused by inadequate intake of calories and/or protein. Marasmus is primarily a deficiency of all macronutrients, leading to severe wasting and emaciation, while kwashiorkor is predominantly a protein deficiency
When is it recommended to introduce solid foods to an infant?
Around 4-6 months, while continuing breastfeeding until at least 6 months.
Name 3 infant reflexes and describe them.
- Rooting: Turning the head toward touch.
- Sucking: Sucking when roof of mouth is touched.
- Palmar Grasp: Grasping objects placed in hand.
- Moro Reflex: Startle response to sudden movement.
How does body growth in height and weight during the first two years compare to other periods after birth?
It is greater during the first two years than at any other time after birth.
What is the fastest-growing organ in early development?
The brain.
What are synapses and neurotransmitters in the brain?
synapses are connections between neurons; neurotransmitters are chemicals that cross synapses to communicate between neurons.
What is synaptic pruning?
The elimination of seldom-stimulated neurons and their synapses.
What is myelination and what type of brain cells are responsible for it?
The coating of nerve fibers with myelin (a fatty substance that speeds up signal transmission); glial cells are responsible.
Name two methods used to measure brain functioning in infants and
EEG/ERPs and NIRS are both non-invasive brain imaging techniques that offer valuable insights into brain activity. EEG/ERPs (Electroencephalography/Event-Related Potentials) measure electrical activity, while NIRS (Near-Infrared Spectroscopy) measures changes in blood oxygenation, reflecting metabolic activity.
What is the prefrontal cortex responsible for?
Complex thought, planning, and decision-making.
What is brain plasticity and why is it high in the first few years of life?
The brain’s ability to reorganize and adapt; it’s high because many areas are not yet committed to specific functions.
What is the difference between experience-expectant and experience-dependent brain growth?
Experience-expectant relies on ordinary experiences; experience-dependent relies on specific learning experiences.
How do infants’ sleep patterns typically change over the first two years?
Periods of sleep become fewer but longer, increasingly conforming to a night-day schedule.
What do habituation and recovery reveal about infant learning and memory?
They show that babies are attracted to novelty and can remember familiar stimuli.
What are two important environmental factors that influence motor development in the first two years?
Movement opportunities and a stimulating environment.
Describe the typical progression of grasping skills in the first year.
From a clumsy ulnar grasp to a more refined pincer grasp.
