The Dopamine Receptor D4 Gene 7-Repeat Allele Interacts with Parenting Quality to Predict Effortful Control in Four-Year-Old Children

<table>Gene by environment interaction showing EC ratings as a function of quality of parenting and the presence or absence of the 7-repeat allele of the DRD4 gene. Parenting quality is a continuous variable in the analyses. The shape of this interaction is illustrated here using the overall mean, parenting below the 25th percentile (lower-quality parenting) and parenting above the 75th percentile (higher-quality parenting). </table>
