Which statement best describes FPCL testing in infancy?

• A. It is a card-based, forced-choice looking method
• B. It relies on objective electrophysiology
• C. It uses full-field stimuli
• D. It is a patient-report test

Answer: (A)

FPCL testing in infancy is a behavioral, two-alternative forced-choice method that uses acuity cards. An infant is presented with two options, typically a patterned card on one side and a neutral or blank card on the other. The tester observes which side the infant looks toward. If the infant consistently follows the patterned side, it indicates discrimination of the stimulus and helps establish an acuity threshold. This approach relies on the infant’s gaze behavior rather than any physiological recording or verbal report, and it uses localized card-based stimuli rather than full-field illumination.
