The Role Of Prediction Error In Episodic Memory, Kevin D. Mohawk

UNLV Theses, Dissertations, Professional Papers, and Capstones

Predictions play an important role in our everyday lives. We make predictions (whether conscious or unconscious) about what we will encounter. However, we will also experience discrepancies between predictions and observed outcomes (i.e., prediction error; PE). There are inconsistencies in the literature regarding how PE affects memory. Several studies find that PE facilitates memory (e.g., Greve et al., 2019), while others find that it harms memory (Kim et al., 2013). The aim of the present study was to determine which conditions may lead to PE facilitating memory and which conditions may lead to worse memory. We tested two PE models, …

Misidentified Bodies And Missing Data: Exploring Forensic Disempowerment And Skeletal Narratives Of Transgender And Gender-Diverse Individuals In The United States, Taylor M. Flaherty

UNLV Theses, Dissertations, Professional Papers, and Capstones

The bodies of transgender and gender-diverse (TGD) individuals represent a physical nexus of contempt and scrutiny. In the United States (U.S.), TGD people experience disproportionate levels of violence and premature death, contributing to a persistent epidemic of harm. Institutionalized anti-TGD biases have reinforced systemic neglect, leading to the routine exclusion of TGD individuals from research, data collection, and historical archives. The absence of state or federal initiatives to track mortality trends and risk factors among this population further exacerbates their systematic erasure. In particular, forensic scientists have traditionally relied on dichotomous indicators of sexual expression which may fail to account …

Effects Of Altered Somatosensory Input On Gait Kinetics And Kinematics Via Different Footwear In Individuals With Chronic Post-Stroke Hemiparesis, Daniela Casillas, Lesley Ruiz

UNLV Theses, Dissertations, Professional Papers, and Capstones

Purpose/Hypothesis: Individuals with post-stroke hemiparesis walk with significant asymmetries, leading to slow, effortful walking, and a high risk of falls. One contributing factor is altered sensation on the plantar surface. Studies examining altered somatosensory input via insoles, vibration and other tactile stimuli observed improvements in hemiparesis gait. This study investigates whether altering somatosensory input through different footwear can affect kinetics, kinematics and muscle activity during walking post-stroke. We hypothesized the barefoot conditions would have increased dorsiflexion (heel-strike, swing), increased plantarflexion during toe-off, increased muscle activity and kinetics, compared to memory foam conditions.

Participants: 13 individuals with chronic post-stroke hemiparesis (4F/9M, …
