Infant Motor Developement

At what age can most babies sit unsupported?

• 3 months

• 6 months

• 9 months

• 12 months

Answer explanation

Most babies can sit unsupported around 6 months of age. At this stage, they develop the necessary muscle strength and coordination to maintain balance while sitting.

When do most babies start crawling?

• 3 months

• 6 months

• 8 months

• 10 months

Answer explanation

Most babies start crawling around 8 months. At this age, they typically develop the necessary muscle strength and coordination to move on their hands and knees.

The thumb and index finger grasp typically around __ months

Walking typically starts around?

• 12 months

• 1 1/2 year

• 2 years

Gross motor skills involve _____ movements, while fine motor skills involve ____

Answer explanation

Gross motor skills involve large movements, such as running or jumping, while fine motor skills involve small movements, like writing or buttoning a shirt. Thus, the correct answer is 'Large small'.

What are the factors that influence motor developement

• Nutrition and sleep

• Weight and enviroment

• Patience, practice and social interaction

• A Muscle strength, brain maturation, practice

• Hair growth, eye color and appetite

Answer explanation

Answer A) Muscle strength, brain maturation, practice is correct because these three factors directly influence motor development:

Muscle strength: Babies need muscle strength for movements like sitting, crawling, and walking. Stronger muscles allow for more stable and coordinated movements.

Brain maturation: The brain controls movements, and as it matures, movements become more deliberate and coordinated.

Practice: Repeated practice improves motor skills. The more a baby practices, the better their movements (like walking) become.

The other options are not fully correct:

B) Nutrition, sleep, brain maturation: Nutrition and sleep are important for overall health but don’t directly influence motor skills. Muscle strength and practice are key.

C) Weight, nutrition, environment: A baby’s weight may affect development, but not as much as muscle strength and brain maturation.

D) Patience, practice, social interaction: Patience and social interaction support development but don’t directly influence the biological and neurological processes that drive motor skills. Muscle strength, brain maturation, and practice are essential.

Which of the following is an example of a gross motor skill

• 
• 
• 

When can babies usually transfer objects from one hand to the other?

• 3 months

• 6 months

• 8 months

Which statement about muscle strength in babies is correct?

• Lighter babies develop muscle strength faster

• Babies who crawl don’t develop muscle strength

• Muscle strength doesn’t play a role in motor development

• Heavier babies develop muscle strength faster

Answer explanation

Because they have less body weight to support, making it easier for them to move and build muscle

What does brain maturation refer to in motor development ?

• Babies learn faster through social interaction

• Movements become more deliberate and planned over time

• Babies need brain maturation to start crawling

Answer explanation

Brain maturation in motor development means that as children grow, their movements become more deliberate and planned. This reflects the increasing complexity and coordination of their motor skills over time.
