Define sexism,and differentiate between hostile sexism,benevolent sexism,and ambivalent sexism.

Sexism refers to any bias against an individual or a group of individuals based on the individual's or group member's sex.That bias does not necessarily have to be expressed in the form of negative attitudes or behaviors.Negative expressions or behaviors that reflect negative attitudes toward women are referred to specifically as hostile sexism.Some forms of sexism,however,involve the attribution of typically positive traits or qualities.This is referred to as benevolent sexism.Although this might seem to be a contradiction in terms,the problem (according to Glick and Fiske)is that the attributions associated with benevolent sexism,even though they sound positive,are derived from stereotypes that see women in limited ways and often stem from a male­centered perspective.According to Glick and Fiske,not only can people hold both hostile and benevolent sexist attitudes,but also,these attitudes and beliefs can be held simultaneously.They named this ambivalent sexism.
