Educating Spouses May Be Key To Helping Veterans, Shawn J. Gourley

Montview Journal of Research & Scholarship

Veterans’ and family members are facing great difficulties when the veteran returns home to transition into civilian life. Marriages are struggling, and families are being torn apart when the veteran returns home with Post Traumatic Stress Disorder (PTSD). Although there are many programs that have been created to educate spouses about PTSD, however, they often fall short of being able to prepare a family for the actual experience of transition. The Department of Veterans Affairs (VA) is starting to come up with programs to help couples and research is starting to gain empirical support; there are still many couples left …

Parents And Teachers’ Perceptions And Clinical Diagnosis Of Autism Among White And Non-White Groups, Margaret Gopaul

School of Psychology Publications

The pervasiveness of autism has significantly increased over the past 2 decades with the 2014 Center for Disease Control and Prevention report indicating 1 in 68 children are diagnosed with Autism Spectrum Disorder (ASD). Early intervention is recommended as the most effective treatment approach. Nevertheless, previous research has indicated that White children are diagnosed with ASD about 1.5 years earlier than are Non-White children. A current gap remains in literature regarding ASD and different racial groups, and evidence has been inconclusive regarding disparities in identifying and diagnosing ASD. To fill this gap, this study investigated the relationship between child race, …

Perception Of Facial Expressions In Social Anxiety And Gaze Anxiety, Aaron Necaise

Honors Undergraduate Theses

This study explored the relationship between gaze anxiety and the perception of facial expressions. The literature suggests that individuals experiencing Social Anxiety Disorder (SAD) might have a fear of making direct eye contact, and that these individuals also demonstrate a hypervigilance towards the eye region. It was thought that this increased anxiety concerning eye contact might be related to the tendency of socially anxious individuals to mislabel emotion in the faces of onlookers. A better understanding of the cognitive biases common to SAD could lead to more efficient intervention and assessment methods. In the present study, the Depression Anxiety Stress …

Age-Related Differences In Vehicle Control And Eye Movement Patterns At Intersections: Older And Middle-Aged Drivers, Yusuke Yamani, William J. Horrey, Yulan Liang, Donald L. Fisher

Psychology Faculty Publications

Older drivers are at increased risk of intersection crashes. Previous work found that older drivers execute less frequent glances for detecting potential threats at intersections than middle-aged drivers. Yet, earlier work has also shown that an active training program doubled the frequency of these glances among older drivers, suggesting that these effects are not necessarily due to age-related functional declines. In light of findings, the current study sought to explore the ability of older drivers to coordinate their head and eye movements while simultaneously steering the vehicle as well as their glance behavior at intersections. In a driving simulator, older …

Nurses’ Perceptions Of Self As Role Models Of Health, Shelia Hurley

Electronic Theses and Dissertations

Given the sad state of obesity and lifestyle-related illnesses in the US, nurses, as the largest and most trusted health profession, must take the cause of health promotion seriously and personally. This study seeks to close the gap in knowledge of nurses’ perception of self as a role model of health and personal healthy lifestyle behaviors. This study focuses on four specific behaviors that lead to a healthy lifestyle: limit alcohol, avoid tobacco, improve nutrition, and engage in physical activity. The purpose of this study is to determine the relationship between nurses’ health practices and their perceptions of self as …

Dynamic Tactile Information Is Sufficient For Precise Curvature Discrimination, Jacob R. Cheeseman

Masters Theses & Specialist Projects

Our tactile perceptual experiences occur when we interact, actively and passively, with environmental objects and surfaces. Previous research has demonstrated that active manual exploration enhances the tactile perception of object shape. Nevertheless, the factors that contribute to this enhancement are not well understood. The present study evaluated the ability of 14 older adults to discriminate curved surfaces by actively feeling objects with a single index finger and by passively feeling objects that moved relative to a restrained finger. The curvature discrimination thresholds obtained for passive-dynamic touch were significantly lower than those that occurred during active-dynamic touch. This result demonstrates that …

How To Go Beyond The Body: An Introduction, Guy Dove

Faculty and Staff Scholarship

Embodied cognition represents one of most important theoretical developments in contemporary cognitive science. Many cognitive processes appear to be influenced by body morphology, emotions, and sensorimotor systems. This perspective is supported by an ever increasing collection of empirical studies that fall into two broad classes: one consisting of experiments that implicate action, emotion, and perception systems in seemingly abstract cognitive tasks and the other consisting of experiments that demonstrate the contribution of bodily interaction with the external environment to the performance of such tasks.

Now that embodied cognition is fairly well established, the time seems right for assessing its further …

The Perception Of Symmetry In Depth: Effect Of Symmetry Plane Orientation, Bart Farell

Biomedical and Chemical Engineering - All Scholarship

The visual system is sensitive to symmetries in the frontoparallel plane, and bilateral symmetry about a vertical axis has a particular salience. However, these symmetries represent only a subset of the symmetries realizable in three-dimensional space. The retinal image symmetries formed when viewing natural objects are typically the projections of three-dimensional objects—animals, for example—that have a symmetry in depth. To characterize human sensitivity to depth symmetry, experiments measured observers’ ability to discriminate stereo displays that were symmetrically distributed in depth and those that were asymmetrically distributed. Disparity values were distributed about one of four planes passing through the z-axis and …

Editorial: Neural Implementation Of Expertise, Merim Bilalic, Robert Langner, Guillermo J. Campitelli, Luca Turella, Wolfgang Grodd

Research outputs 2014 to 2021

How the brain enables humans to reach an outstanding level of performance typical of expertise is of great interest to cognitive neuroscience, as demonstrated by the number and diversity of the articles in this Research Topic (RT). The RT presents a collection of 23 articles written by 80 authors on traditional expertise topics such as sport, board games, and music, but also on the expertise aspects of everyday skills, such as language and the perception of faces and objects. Just as the topics in the RT are diverse, so are the neuroimaging techniques employed and the article formats. Here we …

Change Detection In Rhesus Monkeys And Humans, Deepna T. Devkar, Deepna T. Devkar

Dissertations and Theses (Open Access)

Visual working memory (VWM) is the temporary retention of visual information and a key component of cognitive processing. The classical paradigm for studying VWM and its encoding limitations has been change detection. Early work focused on how many items could be stored in VWM, leading to the popular theory that humans could remember no more than 4±1 items. More recently, proposals have suggested that VWM is a noisy, continuous resource distributed across virtually all items in the visual field, resulting in diminished memory quality rather than limited quantity. This debate about the nature of VWM has predominantly been studied with …

Short-Term Visual Deprivation, Tactile Acuity, And Haptic Solid Shape Discrimination, Charles E. Crabtree

Masters Theses & Specialist Projects

The visual cortex of human observers changes its functionality in response to visual deprivation (Boroojerdi et al., 2000). Behavioral studies have recently documented enhanced tactile abilities following a short period of visual deprivation (Facchini & Aglioti, 2003; Weisser, Stilla, Peltier, Hu, & Sathian, 2005). The current study investigated the effects of visual deprivation on two unique tactile tasks. While Facchini and Aglioti observed significant effects of visual deprivation, neither Wong, Hackeman, Hurd, and Goldreich (2011) nor Merabet et al. (2008) observed these effects. Corroborating these more recent results, no difference in grating orientation discrimination performance was observed between the sighted …

Human Centered Design Applied To Perceptual Paradigms, Jonathan T. Fancher

All NMU Master's Theses

This thesis gives three examples of projects that apply knowledge from areas such as human centered design, computer science, and psychology to study sensation and perception. All three of these projects were created to gather information on how humans interact with their surrounding environment and the world. For instance the first area of discovery included the way humans interact within their perceptual and personal space through an interactive table. The second project looks at exploring the neural mechanisms that affect Haptic Hallucinations by creating a device that can give the feeling of bugs crawling on or below the surface of …

Anger In The Courtroom: The Effects Of Attorney Gender And Emotion On Juror Perceptions, Christian B. May

Honors College Theses

This study sought to examine the effects of gender stereotypes of emotional expression on jurors’ perceptions of an attorney’s competence. Participants watched a video of a closing statement of a male or female attorney expressing either anger or neutral emotions and were asked to give a verdict and rate the attorney’s competence. Participants rated an angry male attorney highest in competence and an angry female attorney lowest in competence. Results also showed that participants who viewed a male attorney were more likely to attribute the attorney’s emotions to the situation compared to participants who viewed a female attorney. The implications …

Effects Of Perceptual Fluency On Reasoning And Pupil Dilation, Juan Diego Guevara Pinto

Honors College Theses

Research on perceptual disfluency has examined the effects of perceptually demanding stimuli on information processing and reasoning, suggesting that disfluent stimuli elicit slower and more effortful processing. Recent criticism of perceptual disfluency, however, suggests that the effects disfluent stimuli have on processing are marginal, and that they are mediated by individual differences. Participants completed a computerized reasoning task presented in either a fluent (i.e., easy-to-read font) or disfluent format (i.e., hard-to-read font) while pupil diameter was measured by an eye-tracker system. Pupillometry is an established reliable measure of mental activity that reflects differences in cognitive load. Results showed no performance …

Examining The Relationship Between Familiarity And Reliability Of Automation In The Cockpit, Rian Mehta, Steven Rice, Scott Winter

Publications

This study sought to determine the correlation between familiarity and perceptions of reliability, as associated to specific aviation-related automated devices. Participants’ experience levels ranged from non-pilots to novice pilots to certified flight instructors. It was hypothesized that familiarity has a direct correlation with ratings of reliability for various aviation-related automated devices and that the correlation across devices for each participant would be positive. The researchers expected to find a difference in the familiarity-reliability relationship as a function of experience. Findings showed that there was a significant positive correlation between familiarity and reliability for every single automated device. A positive correlation …

The Influence Of Spatial Distance Priming On Test Anxiety And Judgments, Eric R Raap

Masters Theses & Specialist Projects

This paper examined the effects of distance priming on test anxiety and judgment. Research suggests that individuals’ perceived distance can impact their affect and judgments, which sheds light on the principle of “distance equals safety” (Williams & Bargh, 2008). Taking an exam invokes both cognitive and emotional anxiety, such as worry, panic, and tension. It is hypothesized that the distance priming may reduce test anxiety—particularly, the emotionality aspect—as well as perceived test difficulty. The results showed that, counter to the hypotheses, there was no significant difference among the three priming groups in their emotional test anxiety or perceived test difficulty. …

Evaluating The Convergent Validity Of The Measure Of Emotional Connotations, Daniel N. Erosa

McNair Poster Presentations

The Measure of Emotional Connotations (MEC; Barchard, Kirsch, Anderson, Grob, & Anderson, 2012) is a new test that has been developed to measure the ability to perceive the emotional connotations of written language. To examine its convergent validity, the MEC will be correlated with the two emotion perception tasks on the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT; Mayer, Salovey, Caruso, & Sitarenious, 2003). These MSCEIT tasks are valid tests of emotion perception; thus, strong correlations would provide support for the MEC as a valid test of emotion perception.

Stereoscopic Vision's Impact On Spatial Ability Testing, George Takahashi

Purdue Polytechnic Masters Theses

A look into spatial ability testing tools and the variations that past researchers made to focus on key factors that affect test scores, will demonstrate the need for tuning traditional testing methods to accommodate a wider demographic and provide more accurate results. Due to technological limitations of the time, a large variety of past spatial tests were developed by hand-drawings. Within this research, the addition of stereoscopic vision is analyzed to determine the value of said changes on human perception of spatial entities.

Effect Of Anchoring On Perceived Amniocentesis Related Miscarriage Risk Within A Latina Population, Laura E. Panos

Dissertations and Theses (Open Access)

Most recognized pregnancies are completed without difficulty, yet there is always a 3-5% background risk to have a child with a birth defect. Amniocentesis, the most common type of prenatal diagnostic test, is used to detect chromosomal abnormalities, such as Down syndrome. Amniocentesis is associated with a risk of complications that can lead to a miscarriage, which is typically quoted to be between 1 in 300 and 1 in 500. Amniocentesis uptake rates are typically lowest within the Latina community, and although the factors related to this have been studied before, no specific conclusions have been reached.

Knowledge And Perception Of The Role Of Targeted Ultrasound In Detecting Down Syndrome Among A High Risk Population, Ashley M. Henriksen

Dissertations and Theses (Open Access)

The purpose of this study was to determine the perception and knowledge of targeted ultrasound in women who screen positive for Down syndrome in the first or second trimester, and to assess the perceived detection rate of Down syndrome by targeted ultrasound in this population.  While several studies have reported patient perceptions’ of routine ultrasound, no study has specifically examined knowledge regarding the targeted ultrasound and its role in detecting Down syndrome.  A targeted ultrasound is a special ultrasound during the second trimester offered to women who may be at a higher-than-average risk of having a baby with some type …

Investigating Intrinsic And Extrinsic Variables During Simulated Internet Search, Molly M. Liechty, Poornima Madhaven

Psychology Faculty Publications

Using an eye tracker we examined decision-making processes during an internet search task. Twenty experienced homebuyers and twenty-five undergraduates from Old Dominion University viewed homes on a simulated real estate website. Several of the homes included physical properties that had the potential to negatively impact individual perceptions. These negative externalities were either easy to change (Level 1) or impossible to change (Level 2). Eye movements were analyzed to examine the relationship between participants' "stated preferences"[verbalized preferences], "revealed preferences" [actual decisions[, and experience. Dwell times, fixation durations/counts, and saccade counts/amplitudes were analyzed. Results revealed that experienced homebuyers demonstrated a more refined …

Effects Of Embodiment On Perceptual And Affective Responses To Infant Crying, Jennifer B. Bisson

Master's Theses

Three experiments were conducted to investigate how changes in bodily states might be related to perceptions of infant vocalizations. In Study 1, participants were asked to hold a pencil between their lips, mimicking a smile, while listening to infant crying. Although there were no embodied effects for perceptual ratings, results indicated that this manipulation decreased participants’ self-reported, negative affect. In Study 2, participants were played both infant crying and birdsong while exposed to similar embodied manipulations, including activation of muscles related to approach and withdrawal behavior. There were no embodied effects for ratings of crying or for affect. Comparing Study …

The Visual Perception Of Elasticity, Elizabeth Y. Wiesemann

Masters Theses & Specialist Projects

Two experiments were designed to evaluate human sensitivity to elasticity. Elastic objects bend when a force is applied to them. Observers saw two computer-generated bending rods (defined by the motions of 50 dots) on any given trial and were required to judge which rod was more flexible. Elasticity difference thresholds were calculated for each observer for each of three bending conditions. The rods bent in a plane that was either frontoparallel or oriented 42.5 or 85 degrees from frontoparallel. The results showed that observers could precisely discriminate between bending rods of different elasticities, independent of whether the bendings occurred in …
