The interplay of emotional development, social development, and academic performance is complex. C. Cybele Raver's 2002 research has established a strong link between social/emotional development and behavior and school success, particularly in the first few years of schooling. If a child's academic tasks are interrupted by problems with peers, following directions, or controlling negative emotions, the child will have trouble learning to read or staying on task in other educational activities. Research also has linked antisocial behavior with decreased academic performance.
