abstract="Parent- and lab-based observer ratings were employed to examine genetic and environmental influences on continuity and change in inhibitory control (IC) in over 300 twin-pairs assessed longitudinally at 2 and 3 years of age. Genetic influences accounted for approximately 60% of the variance in parent-rated IC at both ages. Although many of the same genetic effects on parent-rated IC were stable across age, there were also novel genetic effects that emerged at age 3 (i.e., genetic factors contributed to both continuity and change in parent ratings of IC). Observed IC displayed a different developmental pattern. Genetic influences were moderate at age 2 (38%) and nonsignificant at age 3 (6%). Change in observed IC across early childhood was due to shared and nonshared environmental factors. <br><br>FINDINGS indicate that it is important to consider the measurement of IC when interpreting developmental and etiological findings.<br><br>(c) 2016 APA, all rights reserved).<p /> <p>Language: en</p>",
