[10] In 1987, Den received the first APA Award for Distinguished Contributions to Education and Training in Psychology.

[10] In 2002, Denmark was given the Distinguished Faculty Achievement Award from Dyson College of Pace University.

Denmark has made significant strides for the field of psychology in the areas of gender differences and feminism.

While she has spoken on behalf of women and the feminism movement, she also worked towards defeating the gender bias toward participants in psychological studies.

In this work, Denmark and her colleagues lay out a series of problems that emerge as a result of sexism in experimental psychology.

When sexism plays a part in these processes, there is a high likelihood that sex differences are not included in the results, which could greatly affect treatment options.
