Question

The Focus on Neuroscience: Vision, Experience, and the Brain box describes the visual experience of Mike May, who regained partial sight in one eye after 40 years of blindness. The text described the fact that Mike was able to quickly identify moving objects, but had trouble identifying complex objects that were stationery, including faces. As your text explains, neuroscientists who worked with Mike believe that Mike's experience reflects the fact that:
(A) motion perception pathways develop later than face and object recognition.
(B) motion perception pathways develop earlier than face and object recognition.
(C) the ability to perceive moving objects requires more cognitive effort than the ability to perceive complex but stationary objects.
(D) Mike was able to combine visual signals from both eyes to identify moving objects

Answer 1

Answer:

(B) motion perception pathways develop earlier than face and object recognition.

Explanation:

In determining how motion visual perception occur in the human brain, it is known that the Perception of spatial aspects of stimuli such as the direction and speed of motion is processed via the dorsal visual stream, with the ventral visual stream primarily suggested to be involved in object recognition.

The light signal from the retina is converted to images which is interpreted in the brain, Mike had troubles identifying complex objects that were stationary because he had no functioning retina to transmit the light signal to the brain for interpretation, this shows that the motion perception pathways is developed earlier than face and object recognition
