Correspondence to: Xiumin Hong, Beijing Normal University. Email: xiuminhong@163.com HE first few years of a child’s life witness the most rapid development in his or her entire life. Promoting the physical and mental health devel- opment of infants and toddlers at the age of 0-3 years is receiving widespread attention in China and abroad. Published in Psychological Development and Education recently, this study analyzes the mechanisms of the effects of fam- ily cognitive environment, child care experiences, and effortful control on the development of infants and toddlers at the age of 0-3 years, selecting parents of infants and toddlers aged between 0 and 3 as respondents. Effortful con- trol refers to individual-initiated self-regulation of emotional responses and behaviors, and it reflects individual differences in self-control,attention ad- justment, and behavioral inhibition and activation. Findings of the study:  Infant and toddler effortful control has a mediating effect between the family cognitive environment and infant and toddler devel- opment, that is, the family cognitive environment influences in- fant and toddler development by acting on their effortful control. High-quality family cognitive environments provide rich oppor- tunities for infants and toddlers to exercise effortful control, al- lowing them to regulate and manage their emotions and behaviors in different tasks, thus contributing to their overall development.  The first half of the mediating pathway “family cognitive envi- ronment-effort control-infant and toddler development” is moder- ated by whether or not the infant or toddler is enrolled in child care, The effect of family cognitive environment on infant and toddler effortful control is greater when they are enrolled in child care and weaker when they do not have any experience in child care. Based on the above findings, the authors suggest that parents and edu- cators should create a cognitively stimulating environment for infants and toddlers at home and in nurseries under the premise of ensuring safety and T mailto:xiuminhong@163.com Vol.10, No.2, 2022 1416 health, which facilitates high-quality parent-child interactions and provides appropriate play materials, and that effortful control should be exercised in daily life to promote infant and toddler development.
