What negative impact can occur if a child's brain does not receive adequate sensory input?

The correct choice highlights a significant consequence of inadequate sensory input in a child's development. Sensory experiences are crucial in the early stages of brain development as they stimulate neural pathways, which are essential for the brain's growth and functioning.

When a child lacks sufficient sensory experiences—such as sight, sound, touch, taste, and smell—their brain may not develop optimally. This lack of stimulation can hinder the formation of important neural connections, which are critical for various cognitive functions. As a result, the child may experience delays in overall brain development, affecting their ability to process information and engage in learning activities effectively.

In contrast, improved learning capacity, reduced problem-solving skills, and enhanced motor skills do not typically align with the consequences of inadequate sensory input. Enhanced motor skills, for instance, usually require sensory feedback and interaction with the environment to develop. Similarly, learning capacity and problem-solving skills are nurtured through a range of inputs and experiences, which would be compromised in the absence of adequate sensory stimulation.
