Elana M. Norman, M.A.

Groups: Previous MA, PHD, and Honor’s Thesis Students

Elana Norman defended her Master’s thesis in 2022. She graduated with a B.A. in Psychology from Emory University. While at Emory, Elana conducted cross-cultural development research in Samoa and continued this work in the Cognitive Development lab with children from the Atlanta area. She went on to research trauma in women and children at the University of Memphis and later worked to understand pre-school children’s narrative development in conjunction with Rhodes College. Elana has worked in a wide range of clinical settings with typical and non-typical developing children, which have provided her with a desire to study the development of coping skills. She is particularly interested in exploring emotion-regulation strategies and looking at how these skills can moderate maladaptive behaviors, increase resilience, and improve an individual’s well-being. Elana strives to conduct research with individuals diverse in ability, race, ethnicity, and socioeconomic status for findings to be most applicable and beneficial.

Sedona Whitmore, M.A.

Groups: Previous MA, PHD, and Honor’s Thesis Students

Sedona defended her Master’s thesis and completed M.A. in ADP at GMU in 2021 and joined an M.A. program in School Psychology at GMU. She graduated with a B.S. in Psychology and a minor in Biology from Virginia Tech in 2018. As an undergraduate, she studied how incremental and entity themes in parent-child discourse correlate with children’s healthy habits and snack choices, and was able to present her findings at both an undergraduate research symposium and the Society for Personality and Social Psychology’s annual convention. After graduating with her B.A., Sedona interned for a family services company in Richmond, VA where she helped counsel elementary-aged, inner city children with behavioral issues. Overall, her research interests include how and to what extent social and emotional experiences in one’s childhood contribute to the development of various internalizing and externalizing mental disorders.

Marissa Davila, Ph.D.

Marissa’s research interests include examining associations between adolescent peer relationships and internalizing behaviors (social anxiety, depressive symptoms) and externalizing behaviors (aggression, risk-taking behaviors, and substance use); associations between discrimination and ethnic-racial identity development and peer relationships; using social network analysis methods to understand how adolescent development is shaped by peer network position, structure, and dynamics, friendships, and antipathies in racially diverse settings.
