Details of the 2-factor ANOVA (Viewing condition × Age) performed on the Δpd, Δacc and Δverg data obtained in Experiment I. The Viewing condition and Age columns describe the main effect of these factors on Δpd, Δacc and Δverg while the Viewing condition × Age column denotes interaction between the two factors. The result of post-hoc Games–Howell testing (with no assumption of equal variance) for Age for Δpd is noted in the text. Post-hoc testing for Age for Δacc and Δverg was not done because the main effect of age was not significant.

	Viewing condition	Age	Viewing condition × Age
Δpd	F(1, 117) = 11.9 p = 0.001	F(2, 117) = 15.4 p < 0.001	F(2, 117) = 0.7 p = 0.51
Δacc	F(1, 117) = 36.1 p < 0.001	F(2, 117) = 0.4 p = 0.23	F(2, 117) = 5.5 p = 0.005
Δverg	F(1, 117) = 22.9 p < 0.001	F(2, 117) = 2.5 p = 0.09	F(2, 117) = 8.3 p < 0.001
