Means and standard errors of PII, and PI and CI for each plane (PIy, PIx, CIy and CIx, respectively) for each frequency band (0.05–0.50 Hz, 0.50–1.50 Hz, 1.50–10.00 Hz) and for each condition, i.e. normal viewing (NV), accommodation with a negative spherical lens of −1 diopter in front of each eye (ACCOM1), accommodation with a negative spherical lens of −3 three diopters in front of each eye (ACCOM3), and with convergent prisms of 8 diopters in front of each eye (PRISM); data from 14 dyslexics and 11 non dyslexic adolescents.
