Ethnic Differences In Depressive Symptoms And Risky Behaviors Among Hispanics And Non-Hispanic Whites, Irma De Santiago May 2016

Ethnic Differences In Depressive Symptoms And Risky Behaviors Among Hispanics And Non-Hispanic Whites, Irma De Santiago

Honors College Theses

There is limited research on Hispanics in regards to experiencing depressive symptoms and the risk factors that accompany it. Understanding how these symptoms manifest in different ethnic groups can lead to the development of appropriate interventions to lower diagnoses. The purpose of this study was to examine ethnic differences in depressive symptoms, ethnic differences in risky behaviors, and to see if the association between depressive symptoms and risky behaviors differs by ethnicity. There were 401 young participants, ages 18 to 25; however, because of the goals of the study we only analyzed the data of 312 participants. Of the participants …


Modeling Hedonic Processing And Anhedonia In Depression, Kevin Mercado Nov 2014

Modeling Hedonic Processing And Anhedonia In Depression, Kevin Mercado

Honors College Theses

Depression is characterized by low positive emotion and a lack of pleasurable experiences, or anhedonia. Past studies have emphasized controlling negative affect, but there is an emerging trend in the depression literature to focus on positive emotion. The current study employed several psychophysiological tools, postauricular reflex, startle blink reflex, and event-related potential (ERP) components such as P3 and the late positive potential (LPP), to assess the dissociable components in positive emotion (consummatory and anticipatory processes). In addition, several different hypotheses of emotional dysfunction were evaluated to accurately model deficits in positive emotionality. A majority of the psychophysiological tools used supported …


Early Life Stress, Drug Abuse, Exercise Effects On Bdnf And Sex-Influenced Excercise Differences, Karissa Dold May 2013

Early Life Stress, Drug Abuse, Exercise Effects On Bdnf And Sex-Influenced Excercise Differences, Karissa Dold

Honors College Theses

In 2011, the U.S. reported 3 million child maltreatment cases, an uncomfortably high but recurring figure each year. Research shows exposure to early life stress (ELS) increases an individual’s susceptibility to substance abuse, specifically of nicotine, alcohol, and cocaine. Increased susceptibility may result from dysregulation of the HPA axis sustaining activation into adulthood after ELS. Hyperactivation of the HPA axis significantly reduces hippocampal BDNF, a neurotrophin involved in neuronal growth and plasticity. Reduced hippocampal BDNF may be a factor in substance abuse vulnerability. Additionally, research shows exercise protects hippocampal BDNF from stress induced down-regulation. To explore these relationships, this study …
