Does scotopic sensitivity correction enhance parsing and, thus, comprehension? Twenty-two readers with scotopic sensitivity (X age = 20.3 yrs.; 40.9% male) parsed sentences under scotopic correction and control conditions. Measures included eye-movement indices of parsing and comprehension questions. Although eye movements suggested enhanced parsing, comprehension scores were not significantly improved with correction.
