Final answer:
Executive function is a better predictor of later learning in kindergarten.
Step-by-step explanation:
The preschool factor that is a better predictor of later learning in kindergarten is executive function. Executive function refers to a set of cognitive skills that enable individuals to plan, organize, and control their own behavior. It includes skills like self-control, working memory, and cognitive flexibility. Research has shown that a child's executive function abilities in preschool are strongly associated with their academic and social success in kindergarten and beyond. For example, children with strong executive function skills are more likely to pay attention in class, follow instructions, and manage their emotions effectively. These skills are essential for learning and problem-solving in the classroom.
