Cognitive Performance as a Function of Sleep Disturbance in the Postpartum Period

Description: New mothers often complain of impaired cognitive functioning, and it is well documented that women experience a significant increase in sleep disturbance after the birth of a child. Sleep disturbance has been linked to impaired cognitive performance in several populations, including commercial truck drivers, airline pilots, and medical residents, though this relationship has rarely been studied in postpartum women. In the present study 13 pregnant women and a group of 22 non-pregnant controls c… more

Social Anxiety and Non-Medical Prescription Stimulant Use Among College Students

Description: Current evidence suggests that non-medical prescription stimulant (NMPS) use is on the rise, particularly among college students. Identifying individuals at risk for regular and problematic use is a critical step towards the development of effective intervention efforts. A growing body of work has noted that individuals with elevated levels of social anxiety (SA) or social anxiety disorder are at an enhanced risk for developing substance use problems, including NMPS use disorder. Despite the re… more

Real Time Assessment of a Video Game Player's State of Mind Using Off-the-Shelf Electroencephalography

Description: The focus of this research is on the development of a real time application that uses a low cost EEG headset to measure a player's state of mind while they play a video game. Using data collected using the Emotiv EPOC headset, various EEG processing techniques are tested to find ways of measuring a person's engagement and arousal levels. The ability to measure a person's engagement and arousal levels provide an opportunity to develop a model that monitor a person's flow while playing video game… more

The Virtual Classroom As a Tool for the Assessment of Automatic and Controlled Processing in Autism Spectrum Disorders

Description: Assessment of executive functioning in neurodevelopmental disorders (e.g., autism) is a crucial aspect of neuropsychological evaluations. The executive functions are accomplished by the supervisory attentional system (SAS) and include such processes as inhibition, switching, and planning. Autism spectrum disorder (ASD) tends to present similarly to other neurodevelopmental disorders (e.g., ADHD). For example, ASD and ADHD may share similar etiological underpinnings in the frontostriatal system… more

An Initial Validation of the Virtual Reality Stroop Task (VRST) in a Sample of OEF/OIF Veterans

Description: Currently, neuropsychologists rely on assessment instruments rooted in century old theory and technology to make evaluations of military personnel’s readiness to return-to-duty or return to their community. The present study sought to explore an alternative by evaluating the validity of a neuropsychological assessment presented within a virtual reality platform. The integration of a neuropsychological assessment into a cognitively and emotionally demanding virtual environment – reminiscent of a… more

Combining Select Blood-Based Biomarkers with Neuropsychological Assessment to Detect Mild Cognitive Impairment among Mexican Americans: A Molecular Neuropsychology Approach

Description: Mexican Americans face a significant health disparity related to the development of Mild Cognitive Impairment (MCI) when compared to other ethnic groups. Recent work has documented the utility of utilizing blood-based biomarkers in the detection of amnestic MCI among this population. Efforts to enhance the utility of biomarkers in detecting disease through the inclusion of select neuropsychological measures, an approach termed Molecular Neuropsychology, has shown promise. The present study soug… more

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

Prevalence and Predictors of Perinatal Mental Health Outcomes

Description: Prior research has identified risk factors that may contribute to the development of maternal stress reactions following childbirth. Specifically, situational factors (e.g., factors associated with childbirth), individual factors, and personality factors, have been explored in a multitude of prior studies. The current study sought to build upon this literature by examining both risk and resilience in a sample of both mothers and fathers via a prospective longitudinal investigation. Baseline ass… more

Life Beyond Betrayal: the Influence of Self-as-context on Self-complexity and Posttraumatic Stress

Description: While current research indicates that traumas high in social betrayal are more closely associated with symptoms of posttraumatic stress and identity disturbances than are traumas low in betrayal, the psychological mechanisms by which identity problems occur are less understood. The current project explored the relationships between traumas high and low in betrayal and their influence on self-complexity, through the RFT and ACT conceptualization of three types of self-experiencing: self-as-conte… more

Complex PTSD As a Less Pejorative Label: Is the Proposed Diagnosis Less Stigmatizing Than BPD?

Description: Clinicians’ attitudes and behaviors toward patients with borderline personality disorder (BPD) are affected by the label’s stigma. Complex posttraumatic stress disorder (CPTSD) was proposed as a comprehensive and less stigmatizing diagnostic category for clients with BPD and a history of complex trauma. Given considerable similarities across both disorders’ diagnostic criteria, the CPTSD framework holds promise as a means to improve therapists’ attitudes towards clients with BPD and a history … more

An ecological measure to screen executive functioning in Multiple Sclerosis: the Picture Interpretation Test (PIT) 360°

Description: This article's aim was to compare the efficiency of the Picture Interpretation Test 360° (PIT 360°) with traditional measures on executive dysfunction in Persons with Multiple Sclerosis (PwMS) and Healthy Controls (HC). Overall, the PIT 360° was concluded to be a quick, sensitive, and ecological tool that captures real-world executive dysfunction in PwMS. This engaging measure is sensitive for the detection of executive deficits since the early phases of the disease.
