About Natasha


Natasha graduated from Lamar University in Beaumont, TX with a B.A. in Psychology. She joined Dr. Eastwick's lab while he was at Texas A&M, where she is currently a 5th year graduate student in the Social Psychology department. Broadly, Natasha's research interests revolve around the factors that predict initial romantic attraction and the adaptive benefits of being in a committed relationship with a partner. More specifically, her current research centers around the following topics:

  • Ovulation and attraction: Many researchers have found that women's ovulatory cycle phase predicts mating behavior and attraction preferences both for men and women. My research examines how these effects occur and whether the timeline of human evolution can generate predictions about when moderators of these effects will emerge (e.g., inter-group aggression, pair-bonding).
  • Self-regulation in romantic contexts: Men tend to engage in sexual behavior that is "off-limits" more often than women do. Is this because men have worse control abilities in this domain than women or because they have stronger sexual impulses to overcome? I am interested in how men's and women's responses to sexual temptation differ at the processing level.
  • Adaptive benefits of attachment bonds: Close relationships are linked to well-being and good health, but are attachment bonds adaptive in other ways as well? Currently, I am examining this question by testing whether inducing thoughts of a romantic partner can enable people to perform better on difficult tasks or acquire new skills.
