Final answer:
Constructional apraxia is a neurological disorder that affects a person's ability to carry out skilled movements. The posterior parietal cortex is the parietal region most associated with this type of apraxia.
Step-by-step explanation:
Constructional apraxia is a neurological disorder that affects a person's ability to carry out skilled movements, such as drawing or building objects. It is characterized by difficulty in visually organizing and assembling parts into a whole, resulting in impaired constructional abilities. Symptoms of constructional apraxia may include difficulty copying drawings, inability to assemble puzzles or objects, and trouble with spatial orientation and alignment.
The parietal region most associated with constructional apraxia is the posterior parietal cortex, which lies between the somatosensory cortex and visual cortex regions. This region is responsible for coordinating visual and motor functions, such as reaching and grasping objects. Damage to this area can disrupt the integration of sensory and motor information, leading to impairments in constructional abilities.
