Impairment caused by lazy eye (amblyopia) or crossed eyes (strabismus) may affect the speed with which a child can mark answers with a pencil on a multiple-choice answer form.
In a new study, children with eye conditions commonly referred to as lazy eye and crossed eyes were slower at marking answers on multiple-choice answer forms typically used in timed, standardized tests.
85 school-age children (average age 10): 47 children with lazy eye, 18 children who had been treated for crossed eyes, and 20 children without these conditions for comparison; study conducted from May 2014 to November 2017.
Children were asked to transfer the pre-marked correct answers from a standardized reading achievement test booklet to a multiple-choice answer form as quickly as possible without making mistakes or reading the text (exposures); time to complete the task (outcome).
Children with lazy eye or crossed eyes required approximately 28 percent more time to complete a 40 question multiple-choice answer sheet than children without eye conditions.
