Stereotypes about men and women in the United States are largely unchanged from 30 years ago, a new study shows, in findings that researchers said could be reflected in this year's presidential election.

Presumptions about personality traits, occupations, behavior and physical characteristics remained consistent over three decades despite women making advances in education and the workplace, said authors of the study published in Psychology of Women Quarterly, a peer-reviewed journal.

The study drew from data collected among some 190 adults in 1983 and 2014.
