Question 41
What is synaptic pruning?
a) Strengthening of unnecessary synapses
b) Elimination of unnecessary synapses
c) Growth of additional neurons
d) Halting of brain development
Correct Answer: b) Elimination of unnecessary synapses
Explanation: Synaptic pruning is the process where unnecessary or weak synapses in the brain are eliminated, which improves the efficiency of neural networks.
Question 42
What are teratogens?
a) Environmental agents that cause developmental malformations (birth defects)
b) Genetic mutations that alter brain structure
c) Natural chemicals promoting growth
d) Essential nutrients for brain development
Correct Answer: a) Environmental agents that cause developmental malformations (birth defects)
Explanation: Teratogens are harmful environmental factors such as alcohol, drugs, or infections that can lead to birth defects during fetal development.
Question 43
What is the role of neurotransmitters in the brain?
a) They store information in memory cells
b) They transmit signals between neurons
c) They process visual and auditory stimuli
d) They develop synaptic connections
Correct Answer: b) They transmit signals between neurons
Explanation: Neurotransmitters are chemicals that allow neurons to communicate with each other by transmitting signals across synapses.
Question 44
What is the sensorimotor stage in Piaget’s theory of cognitive development?
a) A stage of logical thinking in adolescence
b) The stage when infants learn through their senses and actions
c) The stage when children develop language
d) A stage of abstract reasoning
Correct Answer: b) The stage when infants learn through their senses and actions
Explanation: In Piaget's sensorimotor stage, infants explore the world through their senses and motor actions, forming the basis for cognitive development.
Question 45
How can parents positively influence a child’s attachment style?
a) By limiting all interactions
b) By responding consistently and sensitively to their child’s needs
c) By focusing solely on discipline
d) By allowing the child complete independence from birth
Correct Answer: b) By responding consistently and sensitively to their child’s needs
Explanation: A positive attachment style is fostered when parents are responsive, consistent, and sensitive to their child’s emotional and physical needs.
Question 46
What is postpartum depression?
a) A period of unusual sadness after childbirth
b) A time of heightened excitement after childbirth
c) A period of anger directed at the infant
d) A temporary lack of sleep due to newborn care
Correct Answer: a) A period of unusual sadness after childbirth
Explanation: Postpartum depression is a period of intense sadness that can occur after childbirth, affecting the mother’s ability to care for her newborn and herself.
Question 47
What is cephalocaudal development?
a) Development from the midline outward
b) Development from head to tail
c) Growth of extremities before the torso
d) Motor development focused on leg muscles
Correct Answer: b) Development from head to tail
Explanation: Cephalocaudal development refers to the pattern of physical growth and motor control that begins at the head and progresses down to the feet.
Question 48
What is the APGAR score?
a) An evaluation of the mother’s health after birth
b) An assessment of newborns’ physical health, including heart rate and muscle tone
c) A test of cognitive abilities in infants
d) A measurement of the baby’s weight and height
Correct Answer: b) An assessment of newborns’ physical health, including heart rate and muscle tone
Explanation: The APGAR score is used to assess the physical health of a newborn immediately after birth by measuring factors such as heart rate, muscle tone, and reflexes.
Question 49
What is neuroplasticity?
a) The brain’s ability to change and adapt
b) A decline in brain function due to aging
c) The loss of neurons over time
d) The permanent wiring of neural pathways
Correct Answer: a) The brain’s ability to change and adapt
Explanation: Neuroplasticity refers to the brain’s capacity to reorganize itself by forming new neural connections in response to learning or injury.
Question 50
What is infantile amnesia?
a) The inability to remember anything from adolescence
b) The inability to recall memories from the first few years of life
c) The loss of memory due to brain injury
d) A condition that affects only adults
Correct Answer: b) The inability to recall memories from the first few years of life
Explanation: Infantile amnesia is the phenomenon where individuals cannot recall memories from their early childhood, typically before the age of 3-4 years.
