Rebecca Bigler is a developmental psychologist known for research on social stereotyping (based on gender or race), prejudice, and children's perceptions of discrimination.

They attended graduate school at Pennsylvania State University where they began conducting research on gender schemata and internalized sexualization under the supervision of Lynn Liben.

[9] With Liben, Bigler conducted widely cited research on gender differentiation in development, social stereotyping and prejudice.

"[16] Their research has shown that adolescent girls who internalize beliefs about the importance of being sexually attractive to boys show increased rates of body surveillance and body shaming[17] and perform worse in school and on standardized test scores than girls who score low on such beliefs.

[23] In a widely cited study,[19] Bigler examined gender stereotyping in relation to classroom practices.

Teachers may unknowingly impose gender stereotypes upon their pupils when they refer children as boys and girls.
