We have to take into consideration the fact that each child is a unique personality and their social, emotional, intellectual, physical and language development is formed by individual, internal and external factors. These influencing factors can be categorised in different ways. We can regard positive, or protective factors, that enable the child to have a normal or even faster than normal development without any serious hindrances; and negative or risk factors that increase the possibility of developmental delays.
Personal factors influencing child development include motivation and characteristics, disabilities and illnesses and learning difficulties that a child can suffer from.
Children have an innate curiosity to learn and discover and a motivation to find pleasurable activities. When they start school, however, their internal motivation is replaced by a wish to perform well in the eyes of the teacher and to fit in amongst their peers. If their only motivation for learning is to receive good grades and not to be embarrassed in front of their peers, failing a test despite their efforts in learning can lead to a loss of interest and a regression of development.
