Question 1

__________is the turning of an infant's head toward a touch.

Accepted Answer

Rooting is the natural reflex in infants where they turn their head toward a touch or a stimulus near the mouth area, which helps them in finding the source of food. Sucking is another reflex that helps babies feed but is not related to head movement. Grasping is a reflex where babies close their fingers around an object that touches their palm. Assimilating is a cognitive process, not a physical reflex.

Question 2

In the context of perceptual development, which of the following is true of newborns?

Accepted Answer

Newborns are nearsighted when they are born because their eyes are not fully developed. They can only see objects near their face clearly. It takes some time for their visual system to develop and for them to be able to see distant objects clearly.

Question 3

Nadine has a newborn baby boy. The first time her husband turned on the television, the baby drew up his legs and arched his back in response to the sudden noise. In this scenario, the baby exhibited the _____.

Accepted Answer

The description of the baby drawing up his legs and arching his back in response to sudden noise suggests the Moro reflex, which is a startle reflex in newborns characterized by spreading their arms and legs, then bringing them back in as if embracing something, followed by crying. The withdrawal reflex involves pulling away from painful or uncomfortable stimuli, the Babinski reflex involves the fanning out and curling of the toes in response to stroking the sole of the foot, and the palmar reflex involves grasping objects that touch the palm.

Question 4

In the context of the social and emotional development of children, which of the following statements is true?

Accepted Answer

Attachment formed in infancy tends to endure and is important for a child's social and emotional development. Attachment provides children with a secure base from which to explore their environment, regulate their emotions, and form relationships with others. Long-term studies have shown that the quality of early attachment relationships can impact children's development well into adulthood.

B and D are incorrect because attachment is vital for the survival of an infant and separation anxiety is a normal and expected developmental response in babies.

C is incorrect because babies do typically like to maintain eye contact with their caregivers as it helps to establish and strengthen the attachment relationship.

Question 5

Which of the following is true of the placenta?

Accepted Answer

The placenta is a specialized organ that forms in the uterus during pregnancy and is connected to the mother by blood vessels in the uterine wall. It allows for the exchange of nutrients, oxygen, and waste products between the mother and fetus, but does not allow the bloodstreams to mix. Its primary purpose is not to produce androgens, and it is not the same as the amniotic sac.
