Biography 
Liben earned her Bachelors of Arts degree in Psychology at Cornell University in 1968. She then completed her PhD at the University of Michigan in Developmental Psychology in 1972 under the supervision of Scott Miller. Liben began her career as an assistant professor at the University of Rochester before moving to Pennsylvania State University in 1976. She held terms as Editor of the Monographs of the Society for Research in Child Development, Child Development, and the Journal of Experimental Child Psychology. Liben's research has been funded through grants from the National Science Foundation. Research 
Liben worked with Margaret L. Signorella on research examining how children's gender attitudes influence memory. They devised a memory test for first and second graders that involved showing them pictures of women and men in traditional, non-traditional, and neutral occupations. Children were then given a recognition memory test using some the original photos intermixed with foils in which the gender of the person holding the occupation changed. Results suggested that children's memory for the pictures was affected by the extent to which their own gender attitudes were stereotypical and reflected prevailing gender roles. Liben and her student Rebecca Bigler conducted influential research on gender and racial stereotyping and prejudice. The researchers proposed a developmental intergroup theory to explain how biases towards different social groups are shaped by environmental factors, including educational, social, and legal policies. Some of Liben's other research has focused on gender differentiation, i.e., the process of assigning social significance to biological differences between the sexes. One of their studies, which involved 11- to 13-year-olds, aimed to establish the reliability of measures of this construct. The researchers explored relations between children's sex typing of others and sex typing of themselves, and found evidence supporting theoretical distinctions relating to individuals' gender attitudes toward others, the feminine self, and the masculine self.
