Martha Bernal was the first Latina to receive a PhD in psychology in the US. She experienced discrimination growing up which influenced her later work researching minority health and multicultural issues. One of her studies from 1968 involved using behavior modification techniques to treat an 8-year-old boy exhibiting behavioral problems. The treatment successfully reduced his negative behaviors and improved his relationship with his mother. Bernal mentored Melba Vasquez, who later became the first Latina president of the APA.
