Parents have the most important and lasting impact on the overall development and socialization of their child. As children grow up, there are many factors which influence their attitudes and behaviors. It is generally learned first from their parents, then the socialization. This statement shows us that correct form different parts, which are sociological theories, the role of parents and parenting styles, care by others and the influence of society. According to two of the sociological theories are functionalism and systems theory. Functionalism attempts to explain how a society is organized to perform its required functions effectively; it focuses on how the structures function within society. Parents have their own responsibility in the families, they add the concept of reproduction to their children, because a population growth can become wealthier; to take care of the children who cannot care for themselves; they are responsibility teaching the socializing to the them; and controlling the behavior of their children. It is very important and having deeply impact on the development of their children. Systems theory is the other sociological theory that attempts to explain how groups of individuals interact as a system, a set of different parts that work together and influence one another in a relatively stable way over time. Parents have different parts of responsibilities for their children before their children grow up. Mothers have to take care of them and teaching the socializing to them. Fathers have to add the concept of reproduction to their children. Over time, children absorb the concept form their parents, so that parents have a large parts of affect for them. A long time ago, human had divided by different small villages. Both of them are independence that has not been influenced by the others. They also are self-sufficiency. Everyone has their own talent, such as hunting, waving, farming and so on. In that time, family had to provide their economic needs, which are foods and clothes, for the younger and older members. Their responsibility is teaching their children the skills, knowledge, values, and attitudes of their society, children who learn these are able to work and relate to others within appropriate adult roles. In industrial revolution was bringing an unprecedented change in the human family system; children and women were particularly in roles. In that time, the economy shifted from self-sufficiency to commerce which is based on factory production in the city or town, and someone work outside the family home to earn a wage to provide for family. Fathers were the money-earners who worked to provide for their wives and children; mothers were nurturers who worked at home and supported financially by their husbands. Nowadays, family build a close relationship, they will give all of the support to the other member. In this century, fathers are still earning money; most of the mothers are working to share the responsibility of their husbands, some of them leave their work and look after their children. They have to instill the different concept about society and reproduction to their future. When children were grown up, they have to take the responsibility that look after their parents; however, parents will concern their children about their work, and help them to solve the problems. In this days and ages, parents are all playing in important roles for their parents. Parenting styles are one of the other important sides in helping parents develop positive impacts on their children. The commonly views of the family have a direct impact on parenting and parent-child relationships. Parents who have a high value of career and work success will focus on a different value on family time and time with their children than the less. Parents who value the goals and needs of individuals over the family will have a difficult time putting their personal needs on hold to care for family members. Parents who are busy fulfilling their individual needs may not take a lot of time to parent in a democratic or nurturing manner. Instead, they may use punishment to get their children to behave themselves. Parents who spend a great deal of time with their children get to know them better and become more sensitive to their needs. Three basic styles of parenting have been considered: authoritative, authoritarian and permissive. There has been a focus on authoritative parenting, which is characterized by warm, support, acceptance and indirect positive control of the children. It is compared to authoritarian parenting, which is distinguished by more parental control and use of punishment, as well as to permissive parenting, which is typified by few rules and by the children controlling the family situations. Children raised by authoritative parents are better adjustment of psychological and have a better self-concept. In contrast, authoritarian parents use more physical punishment, which has been shown to negatively affect the childs adjustment, especially if it is severe and frequent. Children who experience this type of parenting feel rejected by their parents. They also tend to have more problems with psychological adjustment. Children raised by permissive parents who offer much warmth and encouragement tend to be more irresponsible, impulsive and immature, while children raised by permissive parents who are hostile and rejecting tend to be flighty, anxious, and emotionally impoverished. Hostile parenting practices, such as harsh discipline, unsuppressed anger, and use of negative comments, have been shown to lead to children with low scores in their ability to get along with others. Being raised by a hostile parent has a more negative influence on childs ability to form positive relationships than any other aspect of a childs family background. Positive parenting practices result in positive scores in social relationships, helping behavior, and motor and social development. Overall, the style of parenting is one of the most important and lasting impacts on the overall development and socialization of a child. In this day and age, there are a lot parents passed their children by nanny or child care centre, because of their jobs. There are a lot of cases of child abuse, most of it are not abused by their parents, is nanny or the teacher in child care centre. They will punish and corporal punishment them, because they are noisy. I have an experience on it. My friend had abused by her nanny when she was young. When she was 7, her parent is busy on their job, they are working to high value career, and they do not have any time to look after her. So they let the nanny to take care of my friend. The nanny did not look after her nicely, moreover hurt her. The nanny use the hanger to fetch her and punish her, the nanny put all the pressure on her. Did the nanny think that she just a 7 year-old girl, she might change the behavior because of this case. Finally, her parent known this case fired the nanny and compensation claims. However, my friend gets a big turning point on it. She does not trust anyone more and not contact with people. However, society also can impact on the overall development and socialization of the children. There are lots of attractive activities, such as drugs, alcohol, and cigarette and so on, in the society, children will feel curious. Children may be together with the bad guys who with affect their behavior. However, if parents discipline their children in the best ways, children cannot impacted by the other people. Therefore, parents are important and lasting impact on the overall development and socialization of their child.
