Question 1

Research suggests that the age at which toilet training takes place has risen over the years.In 1999, what percentage of children had been toilet trained by 18 months of age?

Accepted Answer

According to the information given in the question, it suggests that toilet training has been happening at a later age, which means less children would have been trained by 18 months of age. Therefore, the best choice would be A) 25%, as it is the lowest percentage option given.

Question 2

In 1999, what percentage of 36-month-old toddlers had been toilet trained?

Accepted Answer

In 1999, approximately 60% of 36-month-old toddlers had been toilet trained. This reflects practices and norms around toilet training at the time, which have evolved and varied over the years.

Question 3

The left hemisphere of the brain becomes more specialized during the preschool years in which of the following areas?

Accepted Answer

During the preschool years, the left hemisphere of the brain becomes more specialized in tasks that involve thinking and reasoning. This hemisphere is generally associated with analytical and language tasks, which include reasoning skills.

Question 4

By what age would a child be expected to jump, hop on one foot, skip, and run?

Accepted Answer

By the age of 3, a child is usually able to jump with both feet, hop on one foot, skip, and run with coordination.

Question 5

During the preschool years, which part of the brain demonstrates a growth in nerve connections and is responsible for sophisticated information processing?

Accepted Answer

The cerebral cortex is responsible for sophisticated information processing and demonstrates a growth in nerve connections during the preschool years.

Question 6

Neuroscientists have discovered growth spurts in the brains of children who are _________ years of age, a time associated with the development of language abilities.

Accepted Answer

Neuroscientists have identified significant brain growth spurts in children aged 1½ to 2 years, a critical period for the rapid development of language skills. This growth is believed to support and facilitate the acquisition and expansion of language abilities during this pivotal developmental stage.

Question 7

Research suggests that the age at which toilet training takes place has risen over the years.In 1957, what percentage of children had been toilet trained by 18 months of age?

Accepted Answer

In 1957, research indicates that 92% of children had been toilet trained by the age of 18 months. This high percentage reflects the toilet training practices and societal expectations of that era, which have since evolved, leading to a shift in the age at which children are typically toilet trained today.

Question 8

What is the name of the protective insulation that surrounds parts of neurons and speeds the transmission of electrical impulses along brain cells but also adds to brain weight?

Accepted Answer

Myelin is the protective insulation that surrounds parts of neurons and speeds up the transmission of electrical impulses along brain cells. However, myelin also adds to brain weight. The other options, such as reticular formation, corpus callosum, and cerebellum, serve different functions in the brain.

Question 9

By the end of the preschool period, the ________ part of the brain has grown significantly because it becomes considerably thicker with individual fibers that help coordinate brain functioning between the two hemispheres.

Accepted Answer

The corpus callosum connects the two hemispheres of the brain and helps coordinate communication between them. It is known to grow significantly during the preschool period, becoming thicker with individual fibers that aid in its functioning.

Question 10

What is the process in which certain cognitive functions are located more in one hemisphere of the brain than in the other?

Accepted Answer

The process in which certain cognitive functions are located more in one hemisphere of the brain than in the other is called lateralization.

Question 11

The Wilson family went to their family reunion picnic, and their two children were allowed to participate in different games.Which of the following is a game that the 4-year-old would likely have enough fine motor skills to play?

Accepted Answer

The answer of The Wilson family went to their family...

Question 12

During the preschool years, which part of the brain demonstrates a growth in nerve connections and is responsible for balance and movement?

Accepted Answer

The cerebellum is responsible for balance and movement and experiences significant growth in nerve connections during the preschool years. The cerebral cortex is responsible for higher-level cognitive processes and does not experience significant growth during this time. The corpus callosum is responsible for connecting the two hemispheres of the brain and also does not experience significant growth during this time. The hippocampus is responsible for memory and also does not experience significant growth during this time.

Question 13

During early childhood, boys typically _______________, while girls _______________.

Accepted Answer

During early childhood, boys typically have greater muscle strength, while girls typically have greater limb coordination. This reflects general trends in physical development differences between genders during early childhood.

Question 14

Which of the following stages is a period during which the general level of activity is extraordinarily high?

Accepted Answer

The answer of Which of the following stages is a...

Question 15

Which of the following fine motor skills can a 3-year-old preschooler perform?

Accepted Answer

The answer of Which of the following fine motor skills...

Question 16

The left hemisphere of the brain processes information _________, while the right hemisphere of the brain processes information ________.

Accepted Answer

The left hemisphere of the brain is known for processing information in a sequential, logical, and analytical manner, focusing on details and the components of a task. In contrast, the right hemisphere processes information more globally, focusing on spatial perception, visual imagery, and the overall context or pattern.

Question 17

The right hemisphere of the brain becomes more specialized during the preschool years in which of the following areas?

Accepted Answer

During the preschool years, the right hemisphere of the brain becomes more specialized in spatial abilities such as comprehending patterns and drawings, rather than in verbal activities like reading or speaking, or in logical reasoning.

Question 18

What area of the brain that is associated with memory is completely myelinated in the preschool years?

Accepted Answer

The answer of What area of the brain that is...

Question 19

Considering the hemispheric differences in lateralization related to gender and culture, boys show a greater lateralization of language in the ____________ hemisphere; while girls develop language in _______.

Accepted Answer

Boys show a greater lateralization of language in the left hemisphere, while girls tend to develop language abilities in both hemispheres, indicating a less pronounced lateralization in females compared to males.

Question 20

What area of the brain associated with attention and concentration is completely myelinated by the time a child is 5 years of age?

Accepted Answer

The reticular formation, a network of neurons in the brainstem, is completely myelinated by the time a child is 5 years of age. This area is involved in regulating attention and arousal.
