Some changes over time af fect different groups of people dif ferently. Sex differences are one type of group dif ferences. In the realm of physical development, for example, females go through puberty, on average, two years earlier than males. At the other end of life, men in the United States tend to die seven years earlier than women. These are sex dif ferences in development.
Analogous sex dif ferences can occur in the realm of personality development. As a group, men and women suddenly develop dif ferently from one another during adolescence in their average levels of risk taking (men become more risk taking). Men and women also develop differently in the degree to which they show empathy toward others (women develop a stronger awareness and understanding of others' feelings). These forms of personality development are properly located at the group dif ferences level of personality analysis.
Some changes affect different groups of people differently. For example, European American women tend to be, as a group, much less satisfied with their bodies than are African American women with theirs. Consequently, European American women have a higher risk for developing eating disorders, such as anorexia or bulimia, compared with women in other groups.
Other group dif ferences include cultural or ethnic group dif ferences. For example, in the United States, there is a lar ge difference in body image satisfaction between European American women and African American women. European American women tend to be, as a group, much less satisfied with their bodies tha are African American women with theirs. Consequently, European American women are much more at risk for developing eating disturbances, such as anorexia or bulimia, compared with women in other groups. This group dif ference emerges primarily around puberty, when a larger proportion of white women develop feelings of dissatisfaction with their physical appearance, compared with African American women.
