Population binocular rivalry and genetic modeling data. (A) MZ and DZ twin maximum likelihood correlations for binocular rivalry measures (error bars indicate 95% CI). BR, binocular rivalry; Predom, predominance. (B) The variance in binocular rivalry rate, estimated from the AEU (best-fitting) model, was accounted for by a substantial additive genetic component; plus unique environmental influences and measurement unreliability over a period of 2 years. The 30% unreliable variance splits 7% within tests and 23% between occasions. (C) Scatterplot showing very high within-test reliability of binocular rivalry rate (95% CI, 0.92–0.94; n = 722) in 14-year-old twins. (D) Scatterplot showing high retest reliability of binocular rivalry rate (95% CI, 0.58–0.78; n = 97) in twins retested at 16 years of age.
