The Effect of Social Parameters in Determining Prototypes

In this research, we were looking for the effect of three factors including; social class, geographical difference and sex in determining prototypes. Using field research, we gave one questionnaire including 7 questions to 400 students boys and girls at the fourth grade of elementary schools from both north and south of Tehran; accordingly, the social class was determined. The research findings show that People with different social classes, sexes and geographical environment have different prototypes for each category in their minds and these variables, even in the area of one city, can have noticeable effect on children's categorization of different phenomena. On this basis, the educational system needs to be considerate about these differences represented in text books and basic level vocabularies.
