Q: Which equation best represents the sequence of environmental stimulus leading to sensorimotor development?

$\text{Environmental Stimulus} \rightarrow \text{Active Movement} \rightarrow \text{Sensory Feedback} \rightarrow \text{New Motor Response}$

Question 1

Which of the following best describes the principle that as higher brain centers mature, they impose control over lower brain areas during sensorimotor development?

Accepted Answer

Maturation of higher brain centers leads to increased voluntary control over primitive reflexes.

Question 2

A child who continues to exhibit the Moro reflex beyond the expected age may be showing signs of which of the following?

Accepted Answer

Delayed central nervous system (CNS) maturation

Question 3

Which sensory modality is NOT listed as essential for CNS development in early childhood?

Accepted Answer

Olfactory

Question 4

According to the sequence of motor development, which pattern describes the progression from head to toe?

Accepted Answer

Cephalo to caudal

Question 5

Margaret Rood's 4-stage sequence of movement development begins with which stage?

Accepted Answer

Mobility

Question 6

Which of the following is a correct example of Rood's stages in quadruped position?

Accepted Answer

Assume quadruped, hold quadruped, rock in quadruped, reach for a toy

Question 7

If a newborn does NOT exhibit a primitive reflex within the expected time period, what might this indicate?

Accepted Answer

Developmental delay

Question 8

Which sequence correctly describes the typical progression of motor development?

Accepted Answer

Reflexive → Voluntary → Gross → Fine

Question 9

Why is sensory stimulation particularly important between 5 months gestational age and 2 years of age?

Accepted Answer

Major nerve growth in the brain occurs during this period.

Question 10

Which of the following is a primitive reflex that typically remains throughout life?

Accepted Answer

Knee jerk reflex

Question 11

A therapist observes a child who cannot dissociate arm movement from trunk movement. Which stage of motor development is likely not fully integrated?

Accepted Answer

Disassociated movement

Question 12

Which of the following best explains the relationship between sensory feedback and motor response in sensorimotor development?

Accepted Answer

Sensory feedback modifies and refines motor responses, promoting development.

Question 13

During which stage of Rood's sequence does a child move while maintaining a position, such as rocking in quadruped?

Accepted Answer

Mobility superimposed on stability

Question 14

Which pattern of motor development describes the progression from gross motor skills to fine motor skills?

Accepted Answer

Gross → Fine

Question 15

A child who skips a stage in sensorimotor development may experience which of the following?

Accepted Answer

Possible problems associated with movement patterns

Question 16

Which of the following is NOT a reason why knowledge of primitive reflexes is important for clinicians?

Accepted Answer

Diagnosing cardiovascular disease

Question 17

Which equation best represents the sequence of environmental stimulus leading to sensorimotor development?

Accepted Answer

$	ext{Environmental Stimulus} ightarrow 	ext{Active Movement} ightarrow 	ext{Sensory Feedback} ightarrow 	ext{New Motor Response}$

Question 18

Which of the following is a protective function of primitive reflexes?

Accepted Answer

They help infants respond to potentially harmful stimuli.

Question 19

In the context of motor development, what does the pattern 'proximal → distal' refer to?

Accepted Answer

Development progresses from the center of the body outward to the limbs.

Question 20

Which of the following best describes the transition from gravity-dependent to anti-gravity movements in motor development?

Accepted Answer

Children develop gravity-dependent movements first, then progress to anti-gravity movements.
