What term describes the application of generalizations about one individual to all individuals within that same group?

The correct answer is stereotyping, which refers to the oversimplified and generalized beliefs or assumptions about a group of people based on their membership in that group. This can involve attributing certain characteristics or behaviors to all individuals of that group, regardless of their unique traits or circumstances. Stereotyping often leads to misconceptions and can harm interpersonal relationships by preventing people from recognizing the individuality of others.

Understanding stereotyping is crucial in gerontology and healthcare, as it impacts how various groups, especially older adults, are perceived and treated. When healthcare professionals rely on stereotypes, they may overlook the diverse needs and experiences of their patients, leading to inadequate care and support.

The other terms presented do not convey the same meaning. Ethnicity refers to shared cultural or national characteristics and identities, which does not inherently imply generalizations about individuals. Ethnocentrism involves evaluating other cultures based on the standards of one's own culture, which is a different concept focused on cultural bias rather than individual characterization. Health disparities highlight differences in health status or outcomes between different population groups, and this term does not address the act of generalization about individuals within a group.
