Measures of child behavior from parent-report utilizing the Child Behavior Checklist and the impact of gender and infant sensory gating ability. Nonparametric analyses of covariance were applied to each 40-month-old behavior score after a rank transformation^{38, 39} to estimate the association with gender and infant P50 sensory gating. All analyses of covariance have the same degrees of freedom: ndf=1, ddf=46.
