The term 'development' refers to a progressive series of changes that occur in an orderly, predictable pattern as a result of maturation and experience. There is a natural arrangement of changes in the individuals, and each change is dependent upon the preceding ones, and also affects the following ones. The changes within the development are called 'progressive' because they enable an individual to adapt to and adjust to his/her environment - physical, social, emotional, etc. Characteristics of development are:Development is a continuous process, it occurs throughout life, and the pace of development may be varying at different ages.Development is sometimes predictable as it follows a similar pattern of development as Cephelocaudal and Proximodistal.Developments depended on both heredity and environment, according to Woodworth development is a product of heredity and environment.Example: Color of eyes, hairs of the child is same as their parents because of inheritance.Children can learn much from their environment as such, from school culture, their society, their peer groups, etc.Development is not linear in shape it is spiral and it can be back and forth throughout life.In the given question, Sunita's parents encourage her to dance by clapping, which shows that her parents also have an interest in dancing, so she is also familiar with dancing, and they provide her with the environment of dancing by clapping, by encouraging her.So, Option (1) is the correct answer.Important Points Development is Life-Long?/Principle of continuity:This principle defines development as a life-long process as it does not stop at maturation and continues gradually until reaching its maximum growth. Development is modifiable?: Development may be explained as the series of overall changes in an individual due to the emergence of modified structures and functions that are the outcome of the interactions and exchanges between the organism and its environment. The development follows a pattern: Prenatal (before birth) and postnatal (after birth) development of human beings follow a pattern or a predictable sequence. Physical development, motor or language development and intellectual development take place in definite sequences.
