Heredity is the transmission of genetic characteristics from parents to children. Heredity characteristics also include certain aptitudes, a capacity to learn a particular skill or acquire a specific body of knowledge. Overall, heredity includes inherited characteristics, biological drives, and limits.
Birth order effects peoples personality a lot as well. Children with siblings view the world different than people without brothers or sisters. The order in which we are born also effect our personalities. For example, in one study first born children were more likely to be achievement-oriented and responsible. Later born children tended to be better in social relationships and to be more affectionate and friendly.
Parental characteristics, like age, can effect the relationship between a parent and child. Some parental characteristics that can influence a child’s personality are levels of education, religious orientation, economic status, cultural heritage, and occupational background.
Cultural environment has a very strong influence on personality development. Generally, the cultural environment determines the basic types of personality that will be found in society. Each culture gives rise to a series of traits that are typical of members of that society. For examples, in the United States competitiveness, assertiveness, and individualism are common personality traits.
Subjective Method is a technique used to rank individuals according to social class in which the individuals themselves are asked to determine their social rank. Researches found that when asked this question most people do not like to say they are in upper or lower classes. Most people place themselves in the middle class.
Objective Method is a technique used to rank individuals according to social class in which sociologists define social class in terms of factors such as income, occupation, and education. This is overall the least biased method.
