Computational and Statistical Modeling of the Virtual Reality Stroop Task

Description: The purpose of this research was two-fold: (1) further validate the Virtual Reality Stroop Task HMMWV [VRST; Stroop stimuli embedded within a virtual high mobility multipurpose wheeled vehicle] via a comparison of the 3-dimensional VRST factor structure to that of a 2-dimensional computerized version of the Stroop task; and (2) model the performance of machine learning [ML] classifiers and hyper-parameters for an adaptive version of the VRST. Both the 3-D VRST and 2-D computerized Stroop tasks … more

Neurociencia Bicultural: Testing the Effects of Culture on Recognition Memory in Bicultural Latinxs

Description: Past research has provided evidence for cultural differences in episodic memory when comparing European American and East Asian samples. However, cultural cognitive neuroscience has become over-dependent on European American vs. East Asian samples, which has left very little research into groups outside of this dichotomy. The aim of this dissertation was to address the need of more diverse samples in cultural cognitive neuroscience and to address the lack of research on Latinx biculturals. In t… more

However, findings on the specific effects of emotional expression have been inconsistent based on the emotions investigated, women's identity characteristics, and workplace contexts. The present project investigated the contributions o… more

Simultaneous Effects of Sleep Disturbances and Negative Emotions on PTSD Symptom Trajectories: From Early to Chronic Trauma Response

Description: The present study aimed to investigate sleep disturbances and negative emotions as predictors of posttraumatic stress disorder (PTSD) symptom trajectories in a publicly available longitudinal dataset of patients (N = 1127; mean age = 36.53; SD = 13.29; 65.5% women) who presented to a U.S. emergency department (ED) in the early aftermath of a trauma exposure. Latent growth curve models were fitted iteratively to characterize PTSD symptom trajectories over 1-year. Models then examined the simulta… more

"Vine of the Soul": The Potential of Ayahuasca for Reducing Depression, Anxiety, and Stress among Ceremony Participants and the Role of Rumination

Description: Rumination is a well-established risk factor for the onset and maintenance of depression and anxiety and has been identified as a transdiagnostic factor due to its association with multiple forms of psychopathology. A renaissance of psychedelic research shows promise in treating psychopathology with potential for acting on ruminative processes. Despite the growing interest and developments in legality, very few research studies have investigated the psychological consequences of participating i… more
