Neurochemistry, Physiology, And Behavior In A Model Of Gulf War Illness, Victoria A. Macht

Theses and Dissertations

Upon returning from the first Gulf War, soldiers cited a plethora of unexplained physical and cognitive deficits which have since been termed Gulf War Illness (GWI). Presentation of GWI is positively correlated with pyridostigmine bromide (PB) use, which was prophylactically administered to soldiers in response to threats of chemical warfare. To test the overarching hypothesis that PB interacted with stress of deployment to alter neural, endocrine, and immune systems, the following studies used a 2×2 rodent model with 14 days of drug treatment (vehicle; PB) and 10 days of repeated restraint stress (stressed) or non-stressed-control conditions. Results indicate that PB …

How Do Angry Drivers Respond To Emotional Music? A Comprehensive Perspective On Assessing Emotion, Seyedeh Maryam Fakhr Hosseini

Dissertations, Master's Theses and Master's Reports

Driving is a complicated task that requires the coordination of visual and sensory-motor skills. Unsafe driving behavior and accidents can happen regardless of the level of drivers’ experience. The main cause of the most of these accidents is human error. Emotions influence the way drivers process and react to internal or environmental factors. Specifically, anger elicited either from traffic or personal issues, is a serious threat on the road. Therefore, having an affective intelligent system in the car that can estimate drivers’ anger and respond to it appropriately can help drivers adapt to moment to-moment changes in driving situations. To …

Narcissistic Intolerance: Verbal Hostility And Dismissiveness In Response To Subjective Disagreement, Wan Wang

Theses and Dissertations (Comprehensive)

We examine the novel proposition that disagreement on matters of opinion may threaten narcissists’ self-esteem and cause them to express dismissiveness of differing opinions and hostility toward the dissenter, a phenomenon we refer to as narcissistic intolerance. In three studies, participants ostensibly read about an earlier participant’s opinion on a painting (Studies 1 & 2, MTurk samples) or TV show (Study 3, undergraduate sample) that agreed or disagreed with the participant’s own opinion. Participants then wrote a response to the opinion, as though they were responding on an anonymous Internet message board. We coded participants’ responses, finding that participants higher …

Investigating The Roles Of Mechanoreceptive Channels In Tactile Apparent Motion Perception: A Vibrotactile Study, Phill Kim, Philip Servos Dr.

Theses and Dissertations (Comprehensive)

Tactile apparent motion (TAM) is a perceptual phenomenon in which consecutive presentation of multiple tactile stimuli creates an illusion of motion. Employing a novel tactile display device, the Latero, allowed us to investigate this. The current study focused on the Rapidly Adapting (RA) channel and Slowly Adapting I (SAI) channel on the index finger. The experiment implemented vibrotactile masking stimuli to target the mechanoreceptive channels with the goal of gaining better insight into the involvement of mechanoreceptive channels in the perception of TAM. Masking stimuli were used because previous studies have used them to differentiate between different channels; a …

Delay Discounting And Cannabinoid Enzyme Inhibitors, Devin Andrew Galdieri

Graduate Theses, Dissertations, and Problem Reports (ETD)

Delay discounting is a measure of impulsive choice that is correlated with maladaptive behavior and psychological disorders. Disruptions to serotonin and dopamine pathways can cause changes in delay discounting, as can lesions to the prefrontal cortex and nucleus accumbens. The endocannabinoid system modulates other neurotransmitter systems, including dopamine and serotonin pathways. Cannabinoid receptors type 1 are found in relatively high concentrations in the nucleus accumbens and the prefrontal cortex. These receptors are activated by endogenous cannabinoids, which are synthesized on demand and broken down by catabolic enzymes. The action of these enzymes can be inhibited by a class of drugs …

Effects Of Reinforcement Rate On The Aversive Function Of Timeout From Positive Reinforcement, Cory Whirtley

Graduate Theses, Dissertations, and Problem Reports (ETD)

Although the use of timeout from positive reinforcement is widespread and has been shown to be an effective punisher in clinical settings, the factors responsible for its effectiveness are not fully understood. The present experiment was designed to evaluate one of these factors, the reinforcement rate underway during periods of time-in. Rats’ lever pressing was maintained on variable-interval schedules of food reinforcement in a multiple schedule with two components. In one component, no timeouts were delivered. In the other component, when a variable-ratio schedule was met, lever presses were followed by a 30-s timeout during which a tone sounded, the …

The Effects Of Automation Transparency And Ethical Outcomes On User Trust And Blame Towards Fully Autonomous Vehicles, Nathan Andrew Hatfield

Psychology Theses & Dissertations

The current study examined the effect of automation transparency on user trust and blame during forced moral outcomes. Participants read through moral scenarios in which an autonomous vehicle did or did not convey information about its decision prior to making a utilitarian or non-utilitarian decision. Participants also provided moral acceptance ratings for autonomous vehicles and humans when making identical moral decisions.

It was expected that trust would be highest for utilitarian outcomes and blame would be highest for non-utilitarian outcomes. When the vehicle provided information about its decision, trust and blame were expected to increase. Results showed that moral outcome …
