A)lateralization.
B)dominance.
C)ambidexterity.
D)asymmetry.

Accepted Answer

Lateralization refers to the specialization of function in one hemisphere of the cerebral cortex or the other, meaning that certain tasks or abilities are localized to one side of the brain or the other. Dominance typically refers to which hemisphere is dominant for language processing, which is typically the left hemisphere for most individuals. Ambidexterity refers to the ability to use both hands equally well. Asymmetry refers to differences in size or shape between the two hemispheres of the brain.

Question 8

The electroencephalogram (EEG)is used to study
A)the levels of blood sugar in newborn infants.
B)hormonal fluctuations in new mothers.
C)the brain's electrical activity.
D)paternal responses to postpartum depression.

Accepted Answer

The electroencephalogram (EEG) is a technique used to study the electrical activity of the brain. It involves placing electrodes on the scalp to measure the patterns of brainwaves produced by neurons in the brain. EEG is commonly used in neuroscience research to study brain function and activity, as well as in clinical settings to diagnose and monitor various neurological conditions. Options A, B, and D are not related to the EEG.

Question 9

Magnetoencephalogy,or MEG,has been used by researchers to study brain development in infants.Researchers have used this technology to study
A)perceptual processes in infants.
B)maternal nutrition habits.
C)paternal influences on the home environment.
D)the effect of having a doula present during delivery.

Accepted Answer

Magnetoencephalogy (MEG) has been used to study perceptual processes in infants, such as their ability to perceive and differentiate between different sounds and speech patterns. It has also been used to study other aspects of brain development in infants, such as how they process visual information and how this changes over time. Maternal nutrition habits, paternal influences on the home environment, and the effects of having a doula present during delivery are not typically studied using MEG.

Question 10

Which lobe of the cerebral cortex has an active role in hearing,language processing,and memory?
A)Frontal lobe
B)Temporal lobe
C)Occipital lobe
D)Parietal lobe

Accepted Answer

The temporal lobe is responsible for processing auditory information and is therefore involved in hearing. It is also involved in language processing, specifically in understanding and producing spoken language. The temporal lobe is also important for memory consolidation and retrieval.

Question 11

During pregnancy,the size of the head is half the size of the total body length when the fetus is ______ old.
A)two-months
B)six-months
C)eight-months
D)nine-months

Accepted Answer

The answer of During pregnancy,the size of the head is...

Question 12

The _____ lobes of the cerebral cortex function in vision.
A)parietal
B)frontal
C)occipital
D)temporal

Accepted Answer

The occipital lobes are primarily responsible for processing and interpreting visual information.

Question 13

Natalie had random hand movements when she was two months old.When she was six months old,she used to grab a block with her whole hand.Now at the age of ten months,she can grasp the same block with her thumb and forefinger.This sequence of growth in her hand and finger movements is according to the _____ pattern.
A)lateralization
B)proximodistal
C)endarch
D)cephalocaudal

Accepted Answer

The sequence of growth in Natalie's hand movements from random hand movements at two months old to being able to grasp a block with her whole hand at six months old and then with her thumb and forefinger at ten months old follows the proximodistal pattern. This pattern describes the sequence of growth starting from the center of the body and moving outwards towards the extremities, such as the hands and fingers.

Question 14

Which of the following is a syndrome that affects a large number of babies in the United States,causes severe brain damage,and includes symptoms such as brain swelling and hemorrhaging?
A)Tay-Sachs syndrome
B)Shaken baby syndrome
C)Shy Drager syndrome
D)Down syndrome

Accepted Answer

Shaken baby syndrome is a type of abusive head trauma that occurs when a caregiver violently shakes a baby, causing brain damage, brain swelling, and hemorrhaging. It is a serious and potentially deadly form of child abuse that can result in long-term disabilities and developmental delays. Tay-Sachs syndrome, Shy Drager syndrome, and Down syndrome are different conditions with distinct symptoms and causes.

Question 15

Which of the following is an example of proximodistal pattern of growth?
A)Abbey learning to sit first before learning to stand or crawl
B)Alex learning to move his eyes before learning his first words
C)Colin learning to stare at moving objects before trying to touch them with his hands
D)Polly learning to grab the objects with her whole hands before learning to pick them up with her fingers

Accepted Answer

The proximodistal pattern of growth refers to the development that occurs from the center of the body outward. Polly learning to grab objects with her whole hands before using her fingers illustrates this pattern, as control develops from the larger, central parts of the body to the smaller, distal parts.

Question 16

Proximodistal pattern of growth refers to the sequence in which
A)the growth and development occurs in a way that parts that are being used more frequently grow faster than parts being used less frequently.
B)the earliest growth always occurs at the top-the head-with physical growth and differentiation of features gradually working their way down from top to bottom.
C)growth starts at the center of the body and moves toward the extremities.
D)growth and development occurs in a way that certain parts are more developed and highly specialized compared to other parts of the body.

Accepted Answer

Proximodistal pattern of growth means growth starts from the center of the body and moves towards the extremities. This means that the trunk and head grow before the limbs and hands. The longest parts of the body, like arms and legs, grow last.

Question 17

The parietal lobes play an important role in
A)hearing,language processing,and memory.
B)vision.
C)voluntary movement,thinking,personality,emotion,memory,sustained attention,and intentionality or purpose.
D)registering spatial location,maintaining attention,and administering motor control.
