Question 1

The integration and coordination of sensory information is called __________.

Accepted Answer

Intermodal perception is the integration and coordination of sensory information from different modalities, such as vision, hearing, and touch. This allows individuals to make sense of their environment and identify objects and events. Binocular vision refers to the ability to see with both eyes and perceive depth, while depth perception is specifically related to the ability to perceive distance and three-dimensional space. Gross motor skills involve the coordination and control of large muscles to perform activities such as walking, jumping, and throwing.

Question 2

Coverage for major infant vaccines is approximately __________ worldwide, but in some African countries the rates are below __________.

Accepted Answer

The answer of Coverage for major infant vaccines is approximately...

Question 3

The key to depth perception is __________, the ability to combine the images of each eye into one image.

Accepted Answer

Depth perception is dependent upon binocular vision, the ability to combine the images from each eye to perceive a single image with depth. The other choices, retinal disparity, myopic vision, and monocular vision, are all related to vision but are not specific to depth perception.

Question 4

__________ in infants was first demonstrated in a classic experiment by Eleanor Gibson and James Walk (1960) with their use of a table called the "visual cliff."

Accepted Answer

The visual cliff experiment by Eleanor Gibson and James Walk was used to demonstrate depth perception in infants. The experiment involved a table with a glass surface that had a checkerboard pattern on the bottom, creating an illusion of a cliff. Infants who have developed depth perception would not crawl off the "cliff" because they perceive it as a drop-off.

Question 5

Relative to the development of intermodal perception, which of the following is the most complex task an 8-month-old infant can perform?

Accepted Answer

An infant can match an unfamiliar person's face with the correct voice when the faces and voices vary on the basis of age and gender. This task requires the infant to integrate information from two different modalities (vision and audition) and to make a cross-modal match. This is a complex task that requires a high level of cognitive development.

Question 6

One of the evolutionary developments that make humans anatomically distinctive among animals is the __________.

Accepted Answer

An opposable thumb is a unique evolutionary development that allows humans to grip and manipulate objects with great dexterity, making them distinctive among animals. It is the thumb that makes humans better toolmakers and users.

Question 7

From research that compares gross motor development of infants from various cultures, it is clear that environment has __________.

Accepted Answer

Research has shown that environment has a relatively small effect on gross motor development by age 6. This is because genetics play a significant role in the development of gross motor skills. However, cultural practices and expectations may influence the opportunities and experiences infants have to practice and develop these skills.

Question 8

__________ is a treatment for diarrhea in which infants are fed a solution of salt and glucose mixed with clean water.

Accepted Answer

Oral rehydration therapy is a specific treatment for diarrhea in which a solution of salt and glucose mixed with clean water is given to infants to replace the fluids and electrolytes lost due to diarrhea. This therapy is a simple, effective way to manage dehydration caused by diarrhea and has been shown to significantly reduce the risk of death in infants and young children with diarrhea. The other choices, Hydro replacement therapy, Saline-based hydration, and Electrolyte replenishment, may be similar in concept but are not the specific treatment used for diarrhea in infants.

Question 9

You have an infant who is 11 months old.She can hold small objects between her thumb and forefinger, such as marbles, coins, and crayons.You are amazed at this ability and believe that she is highly advanced.What is your pediatrician likely to say?

Accepted Answer

The pincer grasp, where a child can pick up small objects between their thumb and forefinger, is a developmental milestone that typically occurs around 9-12 months of age. Therefore, it is not necessarily an indication of being highly advanced, but rather a common stage in early motor development.

Question 10

__________ is the ability to discern the relative distance of objects in the environment.

Accepted Answer

Depth perception is the ability to perceive the relative distance of objects in the environment, allowing us to perceive the world in three dimensions. This ability is achieved through a combination of visual cues such as binocular vision, texture gradients, relative size, and motion parallax.

Question 11

Throughout history, various cultural groups have attempted to protect infants from disease and illness; however, they know very little of the true causes.As a common practice, many cultural groups developed __________.

Accepted Answer

The sentence mentions that cultural groups attempted to protect infants from disease and illness, but they didn't know the true causes. Therefore, they would have relied on practices that likely included specific rituals or customs believed to ward off illness, rather than modern medical interventions like vaccinations or safety devices.

Question 12

Young Claudia reaches out to grasp her blocks and turns them from side to side, often stacking one atop another.It appears Claudia is using her __________ skills to play with the blocks.

Accepted Answer

Claudia is using her small muscle groups, specifically her fingers and hands, to manipulate the blocks. This is an example of fine motor skill development.

Question 13

By 9 to 12 months of age, infants can hold a small object between the thumb and forefinger, such as marbles, coins, and crayons.This is called __________.

Accepted Answer

The ability to hold a small object between the thumb and forefinger is called the pincer grasp. The other options, such as the plantar grasp (grasping with the toes), the drawing grasp (used for holding and manipulating a writing instrument), and the palmar grasp (used for grasping larger objects using the whole hand) do not describe the specific ability mentioned in the question.

Question 14

__________ development includes balance and posture as well as whole-body movements.

Accepted Answer

Gross motor development involves the development of whole-body movements, balance, and posture, such as crawling, standing, and walking. Cephalocaudal motor development involves the development of motor skills from the head to the feet, while fine motor development involves the development of small muscle movements, such as those used in hand-eye coordination and grasping objects.

Question 15

__________ is the basis of fine motor development, the deft movements of our hands that enable us to make a tool, pick up a small object, throw a weapon, or thread a needle.

Accepted Answer

The opposable thumb is crucial for fine motor development and allows us to grasp and manipulate objects with precision. Binocular vision and bipedal motion are important adaptations for primates, but they are not specifically related to fine motor development. The vertical stance may have played a role in freeing up the hands for tool use, but it is not the basis of fine motor development itself.

Question 16

Ache babies are carried nearly every minute of the day and do not walk until around the age of 2 years.This is partly because Ache children prefer to be carried.What are the differences in gross motor development at the age of 6 years between Ache children and children who are not carried exclusively for so long?

Accepted Answer

There is no evidence to suggest that Ache children who are carried exclusively for so long have any significant differences in gross motor development compared to children who are not carried as often. Research actually suggests that infants who are constantly held and carried by caregivers may actually have better motor skills, such as balance and coordination, due to the constant stimulation and movement they receive while being carried. Therefore, it can be assumed that there are no differences in gross motor development between Ache children and children who are not carried exclusively for so long at the age of 6 years.

Question 17

Benton is concerned about reports of a link between autism spectrum disorder and vaccines.His son Gideon is due for his next series of vaccines.Although rumors have circulated on the internet that some immunizations may actually cause harm to children-for example, by triggering autism spectrum disorder or SIDS-scientific studies have found __________.

Accepted Answer

Multiple scientific studies have found no evidence of a link between vaccines and autism spectrum disorder or SIDS. Despite rumors and fearmongering on the internet, the overwhelming consensus among medical professionals and researchers is that vaccines are safe and effective.

Question 18

What is the term that describes the actions that neonates take when they extend their arms awkwardly toward an interesting object?

Accepted Answer

The term that describes the actions that neonates take when they extend their arms awkwardly toward an interesting object is called prereaching. This is one of the earliest motor behaviors seen in infants, and it is not a deliberate attempt to grasp objects, but rather a reflexive action. Primordial grasping refers to the reflexive grip that occurs when an object is placed in an infant's palm, while plantar reflex refers to the reflexive curling of an infant's toes when the sole of their foot is stimulated. Palmar reflex refers to the grasp reflex in which an infant's fingers will close around an object placed in their palm.

Question 19

The ability to combine the images of each eye into one image is called __________.

Accepted Answer

Binocular vision is the ability to combine the images of each eye into one image, allowing for depth perception. Distance vision and far-sightedness refer to the ability to see objects at a distance, while depth perception specifically refers to the ability to judge distance and spatial relationships between objects.

Question 20

The Fulani people of West Africa believe a sharp knife should be kept near the baby to ward off evil witches who might wish to take its soul.Compliments to the baby should be avoided so that the evil spirits will consider the infant invaluable and unattractive.The Fulani people believe unattractive infant nicknames such as "Cow Dung" will keep the evil spirits at bay.This describes how cultures developed __________.

Accepted Answer

The passage describes cultural practices developed by the Fulani people to protect their infants from evil spirits.
