Question

The eye movement called ________ is a tracking mechanism that occurs when a person is reading.
A) vertigo
B) nystagmus
C) saccades
D) none of the above

Accepted Answer

Saccades are rapid eye movements that allow the eyes to quickly move from one point of focus to another. When reading, saccades allow the eyes to jump from one word to the next. Vertigo is a feeling of dizziness, and nystagmus is an involuntary eye movement that can be a symptom of certain medical conditions, but neither are related to reading.
