Final answer:
A selective loss of motion perception is called akinetopsia, a neurological condition where a person can't perceive motion properly while other vision aspects may remain unaffected.
Step-by-step explanation:
The condition known as a selective loss of motion perception is referred to as akinetopsia. This neurological disorder occurs when a person cannot perceive motion correctly, even if other aspects of vision, such as color and shape recognition, remain intact. It is different from other visual disorders like agnosia, which is the inability to recognize objects, faces, voices, or places, or achromatopsia, which is a condition characterized by a lack of color vision. Anomia is the inability to recall the names of everyday objects. Therefore, the correct answer to the question is option b) akinetopsia.
