The Influence Of Negative Mood On Mind Wandering As Observed Through Reach Tracking Techniques, Sydney Tran
The Influence Of Negative Mood On Mind Wandering As Observed Through Reach Tracking Techniques, Sydney Tran
Behavioral Neuroscience Honors Papers
In two experiments, the influence of inducing negative mood on cognitive performance was explored by analyzing physical arm reaching movements as indicators of mind wandering. Mood was induced by viewing a series of six photos per mood condition that were previously established for their emotionally valenced and arousal ratings. A reach tracking device recorded three metrics of arm movement that were expected to reflect instances of mind wandering: initiation latency, movement time, and arm curvature. In the first experiment, 29 participants were randomly assigned into one of two induced-mood groups, negative mood (n = 15) or neutral mood (n = …
Anxiety-Like Behavior In Adolescent Rats Following Maternal Separation And Chronic Cocaine Exposure, Jonathan Handy
Anxiety-Like Behavior In Adolescent Rats Following Maternal Separation And Chronic Cocaine Exposure, Jonathan Handy
Behavioral Neuroscience Honors Papers
Cocaine is one of the most widely used illicit substances in the world and has an addiction rate comparable to opioids. Early Life Stress (ELS) has been shown to have a profound influence on the development of an individual, showing strong correlations to the development of psychiatric disorders and psychostimulant abuse. Adolescents in particular are at a high risk for the abuse of psychostimulants such as cocaine. Previous studies have individually described the correlation between cocaine addiction and anxiety, and the correlation between ELS and cocaine addiction. Rats who have experienced some form of ELS have shown a higher levels …
The Impact Of A Naturalistic Stressor On Spontaneous Alternation Behavior: A New Animal Model Of Ocd, Christina Finch
The Impact Of A Naturalistic Stressor On Spontaneous Alternation Behavior: A New Animal Model Of Ocd, Christina Finch
Behavioral Neuroscience Honors Papers
Over the past few decades, various animal models of obsessive compulsive disorder (OCD) have been developed. Similarly, various stressors have been used throughout animal research. The Spontaneous Alternation Behavioral (SAB) model is a well-established model of OCD while 2,5-dihydro-2,4,5-trimethylthiazoline (TMT) has recently become a popular naturalistic stressor. This study linked the two together, thus modeling the effect of stress on OCD behaviors. After living in an enriched or standard environment for 3 weeks, male Sprague-Dawley rats were exposed to either TMT or no odor, and then were examined in the SAB task. Unlike what was hypothesized, the enriched environment proved …
