Question 1

Toddlerhood lasts from about 12 to 16 months.

Accepted Answer

Toddlerhood typically lasts from about 12 months (1 year) to 36 months (3 years) of age.

Question 2

The American Academy of Pediatrics [AAP] Section on Breastfeeding (2005) recommends that babies be breast-fed for 6 months and that additional nutritional food supplements be also given during this period.

Accepted Answer

The American Academy of Pediatrics recommends exclusive breastfeeding for about the first 6 months, followed by continued breastfeeding as complementary foods are introduced, with continuation of breastfeeding for 1 year or longer as mutually desired by mother and infant.

Question 3

Breast-feeding is inadvisable if a mother has been exposed to radiation.

Accepted Answer

Exposure to radiation can lead to the presence of radioactive materials in breast milk, which can be harmful to the infant.

Question 4

Pediatric experts recommend that iron-enriched solid foods-usually beginning with cereal-be introduced gradually from the age of 3 months.

Accepted Answer

Pediatric experts recommend introducing iron-enriched solid foods, usually starting with cereal, at about 6 months of age, not 3 months, to complement breast milk or formula feeding.

Question 5

The cerebellum, the part of the human brain that controls the senses, grows the slowest during the first year of life.

Accepted Answer

The cerebellum primarily controls balance, coordination, and fine motor skills, not the senses. Additionally, it is one of the fastest-growing brain regions during the first year of life.

Question 6

Most of the early reflexes disappear after 2 years of age.

Accepted Answer

Most early reflexes in infants, such as the Moro reflex and the rooting reflex, typically disappear by around 6 months of age, not 2 years.

Question 7

Early experiences can have lasting effects on the capacity of the brain to learn and store information because of brain plasticity.

Accepted Answer

Brain plasticity, also known as neuroplasticity, allows the brain to change and adapt as a result of experience. Early experiences can significantly influence the development of neural connections, thereby affecting the brain's capacity to learn and store information throughout life.

Question 8

Long-term institutional care in severely deprived settings has a profound negative effect on many areas of development, including physical growth, cognitive development, and social-emotional functioning.

Accepted Answer

Long-term institutional care, especially in severely deprived settings, can lead to significant deficits in physical growth, cognitive development, and social-emotional functioning due to lack of individual attention, stimulation, and emotional support.

Question 9

The senses of smell and taste begin to develop in the womb, and certain taste preferences may be largely innate.

Accepted Answer

Babies can taste and smell in the womb, and these senses develop early on. Studies have shown that infants can develop taste preferences based on their mother's diet during pregnancy, indicating that some taste preferences may indeed be innate or influenced by early exposure.

Question 10

Auditory discrimination develops rapidly after 2 years of age.

Accepted Answer

Auditory discrimination, the ability to recognize differences in phonemes, actually develops significantly within the first year of life, not after 2 years of age.

Question 11

Binocular vision, which enables people to perceive depth and distance, usually does not develop until 4 or 5 months.

Accepted Answer

Binocular vision develops as the visual cortex and the eye muscles mature, allowing the eyes to work together to perceive depth and distance, typically around 4 to 5 months of age in infants.

Question 12

The Denver Developmental Screening Test measures a baby's motor development on the sole criterion of gross motor skills.

Accepted Answer

The Denver Developmental Screening Test assesses children from birth through 6 years of age on four domains: personal-social, fine motor-adaptive, language, and gross motor skills, not solely on gross motor skills.

Question 13

The pace of motor development in babies is independent of cultural factors.

Accepted Answer

Cultural factors, such as parenting practices and societal norms, can influence the pace of motor development in babies. For example, in cultures where babies are encouraged to be more physically active or are given more opportunities for motor skill practice, they may reach motor milestones earlier.

Question 14

By 2 months, almost all infants can keep their heads erect while being held or supported in a sitting position.

Accepted Answer

The answer of By 2 months, almost all infants can...

Question 15

Depth perception refers to the ability to perceive objects and surfaces in three dimensions and depends on cues that affect the image of an object on the retina of the eye where the sensory receptors cells are located.

Accepted Answer

Depth perception is indeed the ability to perceive the world in three dimensions (3D) and to judge the distance of objects. It relies on various visual cues that can be either binocular (involving both eyes, such as stereopsis) or monocular (involving one eye, such as size and perspective cues), which affect how objects are perceived on the retina, where the sensory receptor cells (rods and cones) are located. These cues help the brain to interpret the size, shape, and distance of objects in our environment.

Question 16

The dynamic systems theory refers to Esther Thelen's theory that holds that motor development is a dynamic process of active coordination of multiple systems within the infant in relation to the environment.

Accepted Answer

Dynamic systems theory, as proposed by Esther Thelen, indeed posits that motor development is a dynamic process involving the active coordination of multiple systems within the infant in relation to the environment, emphasizing the interplay between the infant and their surroundings in development.

Question 17

Shaken baby syndrome is also known as crib death.

Accepted Answer

Shaken baby syndrome is a form of abusive head trauma caused by violently shaking an infant, while crib death is more commonly referred to as Sudden Infant Death Syndrome (SIDS) and involves the unexplained death of a seemingly healthy baby during sleep.

Question 18

Foster care is the safest option for children as it does not have any harmful impact on them.

Accepted Answer

While foster care aims to provide a safe environment for children who cannot live with their biological families, it can have various impacts, including emotional, psychological, and sometimes physical harm, due to instability, attachment issues, and potential mistreatment.

Question 19

Children are abused and neglected at all ages, but the highest rates of victimization and of death from maltreatment are for infants and toddlers age 3 and younger.

Accepted Answer

Infants and toddlers are the most vulnerable to abuse and neglect due to their dependency, inability to defend themselves, and the stresses they can place on caregivers who may lack coping mechanisms, leading to higher rates of victimization and fatalities in this age group.

Question 20

Which of the following statements best illustrates the cephalocaudal principle of infant development?

Accepted Answer

The cephalocaudal principle of development states that growth follows a pattern that begins with the head and upper body parts and then proceeds to the rest of the body. Therefore, gaining control over head movements before controlling the arms illustrates this principle.
