Question 1

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

Accepted Answer

There are no differences in gross motor development at age 6 years between Ache children and children who are not carried exclusively for so long, according to the information given.

Question 2

____ 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 the basis of fine motor development as it allows for precise movements and grasping of small objects. The other options, while important for human evolution and development, do not directly contribute to fine motor skills.

Question 3

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 from each eye into one image, which is important for depth perception and judging distances accurately. Distance vision is the ability to see objects clearly at a specific distance, and far-sightedness is a refractive error of the eye that makes it difficult to see objects up close.

Question 4

The integration and coordination of sensory information is called ____.

Accepted Answer

Intermodal perception refers to the ability to integrate sensory information from multiple modalities, such as sight and sound. It is an important aspect of cognitive development, particularly during infancy and early childhood when infants are learning to make sense of the world around them through their senses. Binocular vision and depth perception are both related to visual perception, while gross motor skills refer to the development of large muscle movements.

Question 5

A childless couple interviewed on TV is just about to pick up their three-year-old toddler from an orphanage in Romania known for its terrible conditions.They comment that "love conquers all" and go on to say that "by the time he goes to kindergarten,people will think he has grown up here all his life." Based on the research,is this an accurate prediction? Explain.

Accepted Answer

The answer of A childless couple interviewed on TV is...

Question 6

The ability to discern the relative distance of objects in the environment is called ____.

Accepted Answer

Depth perception is the ability to perceive the relative distance of objects in the environment. Binocular vision refers to the ability of having two eyes that work together to perceive depth, but it is not the same as depth perception. Distance vision refers to the ability to see objects clearly at a certain distance, but it does not necessarily involve depth perception. Far-sightedness is a visual condition that affects the ability to see objects clearly at close distances, and it is not related to depth perception.

Question 7

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

Accepted Answer

Depth perception is dependent on the ability to combine the images from both eyes, which is referred to as binocular vision. This allows the brain to calculate retinal disparity, the slight difference in the image received by each eye, and perceive depth and distance accurately. Monocular vision, on the other hand, is the ability to perceive depth with one eye only and is limited in its ability to gauge distance accurately. Myopic vision refers to nearsightedness and is not directly related to depth perception.

Question 8

____ 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 conducted by Gibson and Walk in 1960 was designed to test depth perception in infants. The experiment involved creating a visual illusion of a cliff by placing a glass surface over a checkerboard patterned surface. Infants between the ages of 6 months to 14 months were placed on the checkered surface, and their behavior and reactions were observed. The results of the study showed that infants who were old enough to crawl perceived the visual cliff as a drop-off and were hesitant to cross it, indicating that they have developed depth perception by this age.

Question 9

By 9 to 12 months of age,infants can hold a small object between their thumb and forefinger,such as marbles,coins,and crayons.What is the name of this ability?

Accepted Answer

The ability to hold a small object between the thumb and forefinger is called the pincer grasp. The plantar grasp refers to the ability of infants to curl their toes around objects, the drawing grasp is a more advanced fine motor skill involving the use of the wrist and fingers to make controlled marks on paper, and the palmar grasp refers to the use of the whole hand to grasp objects.

Question 10

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

Accepted Answer

The opposable thumb is a key evolutionary development that sets humans apart from other animals. It allows for fine motor skills and dexterity, enabling humans to make and use tools, write, and perform other intricate tasks.

Question 11

Describe 3 risk factors for SIDS.

Accepted Answer

The answer of Describe 3 risk factors for SIDS....

Question 12

____ describes a genetically based timetable that individuals are born with.

Accepted Answer

Ontogenetic refers to the development of an organism over its lifetime, including the genetically determined timetable of development. This is often referred to as "ontogenetic programming," which includes the timing of events such as puberty, growth spurts, and cognitive development.

Question 13

The answer of What is meant by plasticity? Give an...

Question 14

Describe the cephalocaudal principle of growth.Is this unique to babies born in developed countries?

Accepted Answer

Question 15

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, which allows infants to hold small objects between their thumb and forefinger, typically develops around 11-12 months of age. Therefore, it is a normal and expected developmental milestone at this age and not necessarily a sign of exceptional advancement.

Question 16

Which of the following is the basis of fine motor development?

Accepted Answer

Opposable thumb allows for the development of fine motor skills as it enables individuals to have better control over their fingers and hands, which is essential for performing tasks that require precision and dexterity.

Question 17

Are there sex differences in length and / or weight at birth? Does this pattern continue? Explain.

Accepted Answer

The answer of Are there sex differences in length and...

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

Prereaching refers to the reflexive action of neonates extending their arms awkwardly toward an interesting object, even though they are not yet capable of purposeful reaching and grasping. The other options, such as primordial grasping or reflexes like plantar and palmar, do not specifically describe this behavior.

Question 19

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

Accepted Answer

Research indicates that while environment can influence gross motor development, genetic factors play a more significant role, leading to the conclusion that the environment has a relatively small effect.

Question 20

In regards 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 (visual and auditory) and to make a cross-modal match. This is a complex task that requires a high level of cognitive development.
