Parents alone decide how to raise the child, the cultural norms, the pressures to put on the child and the way they want to be when they grow up. For example, in China, toddlers are selected by public sports schools. The parents of these children may decide to send their only child to these sports training boarding schools, where they will undergo years of grueling training. But for these parents, it is the best way to raise their child, because they have little chance of bringing honor to their family and China and may have more opportunities for professional success (Tabu). As the oldest and most enduring source of socialization, a child's parents are the first people with whom he or she identifies and remain the greatest influence on his or her development. This primordial importance of parenting has led developmental psychologists to take a close interest in parent-child interactions (George and Rajan, 99). A study of the relationship between child inhibition and parenting styles (Canada versus China) showed that child inhibition was associated with mothers' positive attitudes toward the child, including acceptance, lack of punitiveness and encouragement for achievement among Chinese participants and with punishment and overprotection among Canadian participants. In another study by Sonia George and Amar Rajan, thirteen variables (factors) were identified as child-rearing factors, which constitute the way parents raise their children. Factors include acceptance, punishment, protection, responsibility, responsiveness, reward, understanding, non-criticism, permissiveness, encouragement, relationships, emotional stability, and patience (George Rajan 101 ). To generalize the thirteen variables, the variables include: acceptance/rejection, punishment/reward, and behavior.
