Human Vision Inspires Cortisol And Immune Behaviors, J. Forrest Olsen
Departmental Honors Projects
Ten-minute slideshows of disease stimuli were presented to human participants who donated saliva samples before and after its completion. Much to our surprise, this research found cortisol decreased upon the visual perception of a disease threat, a response depicting the physiological consequences of Behavior Immune System activation. Even subliminal exposure to disease stimuli, totaling only 0.5 seconds over the ten-minute slideshow, was found to elicit a cortisol response.

The Influence Of Emotion On Memory For A Crime, Taylor Langley
College of Graduate Studies: Theses & Dissertations
Researchers have reported errors in recall or recognition of witnessed events, accounting for the most common cause of false convictions of innocent people. Tiwari (2010) indicated that 25% of suspects who were identified in a line-up were actually innocent. Jurors are strongly influenced by eyewitness testimony and this can lead to false convictions. The validity of eyewitness identification is critical in cases in which it is used as evidence. In the current study we examined specific emotion states by inducing fear, surprise, and neutral moods. We hypothesized that participants in the Fear group would be least susceptible to the effects …

An Analysis Of Stakeholders Communication In Collaborative Software Development Projects, Wei Zhang
Dissertations, Master's Theses and Master's Reports
Software development is a multidisciplinary collaboration involving many stakeholders. However, existing software development processes exhibit many issues related to that collaboration. Because prior research on stakeholder analysis and teamwork revealed the importance of communication, this study analyzed stakeholder communication with reference to team activities as a social and cognitive process. The study’s goal was to understand the collaboration process during software development and to delineate factors that influence this process. We focused on communication between the software developers and their clients during the requirements gathering phase, the team process, and the inter-team and interdisciplinary collaboration, in particular between software engineers …

Effects Of Priming The Concept Of Luck On Task Persistence, Koryn R. Haight
Undergraduate Theses, Professional Papers, and Capstone Artifacts
Does feeling lucky influence the way we perform? Do we try harder and persist at tasks if we think luck is involved, or are we more prone to give up? To help answer these questions, this research examines the effect of priming the concept of luck on persistence. In particular, some participants completed a word descramble task designed to prime luck; others completed a neutral word descramble task. All participants then completed a set of reasoning puzzles, one of which they were told was ‘difficult’ but in reality was unsolvable. Persistence was measured by (a) the amount of time participants …

Electronic Cigarette User Plasma Nicotine Concentration And Puff Topography: Influence Of Liquid Nicotine Concentration And User Experience, Marzena M. Hiler
Theses and Dissertations
Electronic cigarettes (ECIGs) aerosolize an often nicotine-containing solution for user inhalation. ECIG nicotine delivery may depend on liquid nicotine concentration and user puffing behavior (topography). This study examined the relationship among liquid nicotine concentration, puff topography, and plasma nicotine concentration. Thirty-three ECIG-experienced and 31 ECIG-naïve individuals completed four laboratory sessions that differed by ECIG liquid nicotine concentration (0, 8, 18, or 36 mg/ml). A 3.3 volt “eGo” ECIG battery attached to a 1.5 Ohm dual coil “cartomizer” filled with 1 ml of 70% propylene glycol/30% vegetable glycerin nicotine liquid was used in two ECIG-bouts (10 puffs; 30 s IPI). Plasma …

The Influence Of Real-Time Visual Feedback Training On Vocal Control, Justeena N. Zaki-Azat
Theses and Dissertations (Comprehensive)
Trained singers have better vocal control when compared to singers without vocal training. The development of precise vocal control, like any motor skill, requires practice with some form of feedback, such as auditory feedback. In addition to auditory feedback, singing training programs use online visual feedback to improve performance accuracy. The purpose of this thesis is to investigate the recent body of literature concerning the cognitive processing of vocal control, and apply this knowledge practically to develop an effective real-time visual feedback training program that enhances vocal control. In the first of two studies, non-singers and singers were randomly assigned …

Measuring Self-Reported Exercise, Motivation To Exercise, And Sexism In Women, Sydney C. Jensen
All Master's Theses
The harmfulness and pervasiveness of benevolent sexism is not a well disseminated issue, despite the belief that women are treated with equality in today’s society. The current study was designed to investigate whether exercise type and motivation to exercise would predict participants’ self-reported benevolent and hostile sexism, particularly in light of gender-related stereotypes about physical activity. A sample of 79 females completed an online survey that included questions about demographic characteristics, primary exercise type (i.e., cardiovascular exercise, weight-lifting, or hobbies), average number hours spent engaging in their primary exercise weekly, exercise motivations, and finally the Ambivalent Sexism Inventory which served …

Anger Maintenance And The Impact Of Shame, Attachment, And Experiential Avoidance, Ahva R. Mozafari
EWU Masters Thesis Collection
Prior to the present study, the relationships between attachment, shame, experiential avoidance, and anger had not been empirically evaluated. This study investigated the influence of shame and attachment style on anger and experiential avoidance. Additionally, this study also explored the differences between those with anxious and avoidant attachment styles and their experiences of anger, as well as their ability to confront emotions. It was hypothesized that the combination of attachment, shame, and experiential avoidance would be predictors of anger. Finally, it was hypothesized that shame experiences would mediate the relationships between attachment and anger as well as attachment and experiential …

The Impact Of Multiple Opportunities For Aggression On Aggressive Thoughts, Behaviors, And Motivations, Kristen Nicole Hull
UNF Graduate Theses and Dissertations
Opportunities for aggression occur frequently and unpredictably, but little research to our knowledge has investigated the impact of the mere presence of multiple opportunities on aggression over time. Two studies, one with a Canadian sample (163 participants) and one with an American sample (103 participants) were conducted to analyze the impact of the number of opportunities for aggression on justified and unjustified aggressive thoughts, behaviors, and motivations. Individually, these studies yielded the result that justified aggression remains stable over time, but that unjustified aggression decreases when an individual is given multiple opportunities. Combined, they indicated that justified aggression increased when …

Early Visual Perception Potentiated By Object Affordances: Evidence From A Temporal Order Judgment Task, Atsunori Ariga, Yuki Yamada, Yusuke Yamani
Psychology Faculty Publications
Perceived objects automatically potentiate afforded action. Object affordances also facilitate perception of such objects, and this occurrence is known as the affordance effect. This study examined whether object affordances facilitate the initial visual processing stage, or perceptual entry processes, using the temporal order judgment task. The onset of the graspable (righthandled) coffee cup was perceived earlier than that of the less graspable (left-handled) cup for right-handed participants. The affordance effect was eliminated when the coffee cups were inverted, which presumably conveyed less affordance information. These results suggest that objects preattentively potentiate the perceptual entry processes in response to their affordances.

The Neural Representation Of Duration In Event Concepts, Christopher Todd Hackett
Theses and Dissertations
Little is known about the neural basis of temporal concepts. Some have suggested that temporal concepts are grounded in spatial or temporal processes. Here we aimed to examine the representation of duration of event concepts, and compare them with judgments of object size, which may entail spatial processing. A 2x2 block design used event and object nouns as stimuli that were presented during functional imaging. Participants made judgments about event duration, object size, and event and object valence. In addition to whole-brain analyses, we examined activations in areas known to be involved in temporal processing and spatial processing. Knowledge of …

Performance Of Individuals And Teams On Cryptographic Tasks: Factors That Affect The Consideration Of Alternative Strategies, Joseph Bihary
Dissertations
The two studies presented here examined factors that might affect teams’ and individuals’ tendency to follow outside advice when attempting to solve a complex problem known as letters-to-numbers. Past research on group dynamics suggests that a lack of group consensus or homogeneity reduces group members’ confidence in their group’s abilities, and may lead members both to seek and accept advice from outside the group. Study 1 experimentally manipulated group diversity in task performance strategies in order to investigate whether dyads whose members have divergent perspectives are more likely than homogeneous dyads to consider and use a problem-solving strategy presented from …

Theses and Dissertations
Maternal smoke exposure produces long-term adverse cognitive and behavioral outcomes in offspring, including an increased likelihood of attention problems (e.g., attention deficit hyperactivity disorder; ADHD) and drug abuse. Preclinical research shows that gestational exposure to nicotine, the primary psychoactive compound in tobacco smoke, influences the neurodevelopment of attention and reward neuronal circuits. This study investigated hypotheses about five brain regions, to determine if prenatal nicotine (PN) exposure altered expression of nicotinic acetylcholine receptors (nAChRs). A low dose, intravenous nicotine (IV) exposure method was used to administer nicotine (0.05 mg/kg/injection) or saline, 3x/day on gestational days 8–21 (Treatment). Brain tissue was …

Self-Efficacy Matters More Than Interruptions In A Sequential Multitasking Experiment, Maureen A. Conard, Robert F. Marsh
Psychology Faculty Publications
Interruptions and multitasking have received a great deal of attention from researchers. The present study is the first to examine task self-efficacy along with interruptions in an experimental multitasking framework. Perceptions of resumption lag times and task rehearsal were also examined. Participants (N= 110) completed a primary task (puzzle) with some being interrupted to pursue a secondary task (a word search) either once or four times. Uninterrupted participants completed the puzzle 26% faster than those interrupted once and 30% faster than those interrupted four times. However, self-efficacy predicted performance much more strongly than did interruptions, and therefore should receive more …

Research shows that heavier alcohol use is associated with physical aggression. Scant research has examined the way in which alcohol relates to other forms of aggression, such as indirect aggression (e.g., malicious humor, social exclusion). Given the possible negative consequences of indirect aggression and the limited evidence suggesting alcohol use can elicit indirectly aggressive responses, research is needed to further investigate the association between drinking behavior and indirect aggression. Additionally, specific alcoholic beverages, such as caffeinated alcoholic beverages (CABs; e.g., Red Bull and vodka), may potentiate aggression above the influence of typical use, and thus warrant examination with regard to …

Authority users often play important roles in a social system. They are expected to write good reviews at product review sites; provide high quality answers in question answering systems; and share interesting content in social networks. In the context of marketing and advertising, knowing how users react to (quails and messages from authority senders is important, given the prevalence of email in our everyday life. Using a real-life academic event, we designed and conducted an online controlled experiment to determine how email senders of different types of authority (department head, event organizer and a general email account) affect the range …

Incentive Contrast As A Relative Reward, Alexandra Schmidt
Honors Projects
This study examines the relationship between rapid relative reward comparisons and incentive contrast among rats (n=5). Animals were trained to lever-press in order to obtain access to a sucrose solution (concentration used: 1%, 10% or 20% in tap water). These rewards were placed outside an operant box which could be reached through a small hole displaying sessions with mixed comparisons (1v20%, 20v1%) or single sessions (1v1%, 10v10%, 20v20%) that rotated between two spouts containing the pre-randomized order of paired blocks; allowing for comparative analysis between two spouts/concentrations and blocks of responses. Throughout weekly testing each animal experienced a …

Color Me, Please: How Color-Emotion Pairs Affect Our Perceptions, Russell T. Rogers
Honors College Theses
Color-emotion pairings are part of everyday experience, and they develop in early childhood. Emotional experiences are typically much stronger when emotional stimuli (e.g., pictures or videos) are paired with sensory stimuli (e.g., sights or sounds). Since the presence of these sensory stimuli seems to heighten the emotional experience of emotion-evoking visual stimuli, it should be the case that such pairings will allow the manipulation of color-emotion pairings through the presence of a color (a visual stimulus) during an emotional situation (such as watching a video). In this study (N = 44), we paired both a positive and negative video …
