Investigating The Ichthus (Fish) Christianity Symbol On Perceived Source Credibility Of Service Providers Under Different Service Evaluation Contexts, Jeri L. Jones, Mahmood T. Shandiz

Atlantic Marketing Association Proceedings

Combining religious practices with commercial pursuits for profit is neither a novel nor an insignificant trend (Belk, Wallendorf, and Sherry 1989; McDannell 1995). Today, marketplace use of Christian symbols in secular advertising is becoming more common, especially in certain geographic locations within the United States. Christian religion-based messages and symbols regularly appear in a wide range of advertisements. The Christian elements in these ads often include Bible verses, crosses, doves, and often, the Christian fish symbol (Ichthus). Similar Christian messages are often observed in outdoor advertising, retail store signage, product packaging, and even the daily newspaper. These examples illustrate that …

Evaluating The Sandcastles Program: A Group Intervention For Children Of Divorce, Lauren A. Shure Phd, Alvaro Domenech Lcsw, Linda Fieldstone M.Ed., Isadore Newman Phd, Gerene Starratt Phd, Tori Burgess

South Florida Education Research Conference

The Sandcastles program has been utilized nationwide as a one-time group intervention to assist children of divorcing parents. For several years Miami-Dade family court services mandated participation in the program for divorcing or separating families. Currently, there is a paucity of research and evaluation to ascertain the efficacy of the program. This symposium will provide details and discussion regarding the planning and process used to establish an evaluation plan to assess the effectiveness of the Sandcastles program for families in MiamiDade County. Any preliminary outcomes available at the time of the symposium will also be shared.

How Can Fredrickson’S Broaden-And-Build Theory Enhance Personal Resources?, Jennifer Danilowski

South Florida Education Research Conference

Abstract: Positive psychology has garnered great attention towards understanding how individuals develop personal resources to enhance wellbeing and flow. Barbara Fredrickson’s broaden and build theory suggests when individuals imbue various personal resources with more positive affect, individuals are more likely able to develop greater resilient assets as a result.

Maternal Prenatal Depression And Anxiety Affect Neonatal Neurobehavior, Shelby Siddall, Jason Gibbs, Aimee Martin, Nicki Aubuchon-Endsley (Mentor)

Idaho Conference on Undergraduate Research

Prenatal depression and anxiety have been linked to impaired infant neurobehavior including altered attention, responsivity, and quality of movement. No known studies have assessed individual and joint effects of prenatal depressive and anxiety on neonatal neurobehavioral outcomes. The current study compared these outcomes among (1) mothers diagnosed with comorbid Depressive and Anxiety Disorders, (2) mothers diagnosed with only Depressive Disorders, (3) mothers diagnosed with only Anxiety Disorders, and (4) mothers with no prenatal diagnosis.

Maternal prenatal diagnoses were assessed by the SCID-I. Offspring neurobehavior was assessed from 1-2 to 30 days using the NNNS. There was a between-subject's effect ( …

A Descriptive Analysis Of The Appropriate Use Of Cognitive Bias Terminology In Forensic Science Literature, Courtney A. Winters, Evelyn M. Buday, Trevor I. Stamper

The Summer Undergraduate Research Fellowship (SURF) Symposium

Cognitive bias occurs without a person’s awareness and can affect decision-making abilities. In forensic science, bias can be especially detrimental to making accurate decisions about the evidence in a criminal investigation. There are many academic studies in identifying, describing, and suggesting ways to mitigate cognitive biases in forensic science. Many authors will give a known cognitive science concept a new name or create their own bias. This is a problem in the literature because nobody knows for sure how many published studies are referring to or testing the same phenomena since authors are using different definitions or terminology to describe …

Interactions Between Maternal Prenatal Obesity And Physiological Stress: Predictors Of Offspring Adult Obesity, Jennifer L. Hambleton, Jared Vineyard, Nicki L. Aubuchon-Endsley (Mentor)

Idaho Conference on Undergraduate Research

Over half of US women of childbearing age are overweight or obese. This is significant because excessive gestational maternal weight may program offspring for greater risk of lifetime obesity. Preliminary research suggests this effect may be moderated by fetal exposure to stress hormones, known to be dysregulated in obese individuals. However, long-term longitudinal research of these constructs is needed.

Therefore, this study used archival data from the NEFS/CPP Studies to examine interactions between maternal pre-pregnancy BMI/gestational weight gain and fetal cortisol exposure as predictors of offspring growth trajectories from birth-7 years and adult BMI via growth curve modeling and ANOVAs. …

Sex Differences In Placental Epigenetic Regulation Of Leptin Hormone Are Associated With Elevated Maternal Gestational Weight Gain, Nicole E. Douthit, Nicki Aubuchon-Endsley Ph.D. (Mentor)

Idaho Conference on Undergraduate Research

In utero epigenetic factors affect health and development, though sex differences in epigenetic effects of prenatal maternal health may exist for placental hormones. Specifically, maternal prenatal obesity affects expression of placental leptin hormone genes, which play a unique role in metabolism and appetite. However, the effects of such expression on infant neurobehavioral development differ by offspring sex.

Therefore, we examined sex differences in the effects of maternal gestational weight on placental leptin gene methylation. Data (n=155) were taken from the Behavior and Mood in Mothers and Behavior in Infants Study. Maternal pre-pregnancy weight was self-reported, while delivery weight …

Electrophysiological And Behavioral Working Memory Differences Between Musicians And Non-Musicians, Benjamin Richardson, Zach Felke, Grace Whorley, Marisha Medrano, Hannah Williams

Symposium Of University Research and Creative Expression (SOURCE)

The current study is an examination of P300 differences between musicians and non-musician groups during a visual oddball task, in addition to behavioral subtests of the TOMAL-2 measuring visual and auditory working memory. Previous research has demonstrated higher amplitude P300 waveforms with shorter latencies of P300 onset in musician groups, indicating a more sensitive and accurate stimulus detection system. Fluctuations of P300 amplitude and latency activity near parietal areas have been used to quantify differences in updating processes of working memory possibly associated with differences in amounts of music experience. The current study is designed to partially replicate a method …

Student Usage And Perceptions Of Digital Devices In The Classroom And While Driving, Elena Larrabee, Hannah Williams

Symposium Of University Research and Creative Expression (SOURCE)

The purpose of this study is to examine Central Washington University students’ use of electronic devices for non-class related purposes and while driving. For the purposes of the study, electronic devices are defined as cellphones, tablets, laptops, and any other devices that are non-essential to the classroom environment, and non-classroom purposes are defined as any non-course specific activities performed on an electronic device during lecture. The survey has two parts, the first focusing on electronic device usage in the classroom, and the second focusing on electronic device usage while operating a vehicle. The survey is administered online, and focuses on …

Auditory Reaction Time And Behavioral Working Memory Differences Between Musicians And Non-Musicians, Benjamin Richardson, Zach Felke, Marisha Medrano, Grace Whorley, Hannah Williams

Symposium Of University Research and Creative Expression (SOURCE)

Previous research investigating working memory functioning between musicians and non-musicians has demonstrated differences related to music experience in auditory reaction tasks. This body of research suggests music experience may be related to faster reaction times to auditory stimuli. In addition to reaction times recorded by clicking a mouse while listening to a tonal oddball, participants in the current study performed six subtests of the TOMAL-2, a standardized measure of working memory ability, documenting participants visual, auditory, and executive functioning modules of working memory. Our hypotheses are that means of performance on all three subtests of the TOMAL-2 will be higher …

The Influence Of Family Upbringing On The Facial Inference Process, Kara Pellegrini, Christopher Benner-Kenagy, Meghan Gilbert, Jacqueline Licea, Jonathan Ojeda, Jordan Segura-Mitchell

Symposium Of University Research and Creative Expression (SOURCE)

This study examined personality trait inferences on the basis of facial expressions by showing participants multiple photographs of either one young female face or one young male face, exhibiting three distinct facial expressions. Participants from two parent homes were asked to indicate which parent was more nurturing, and which parent enacted more disciplinary measures. Results demonstrated that responses to these two questions influenced participant trait responses to the angry and sad facial expressions. Results were discussed in terms of overall environmental influence on the inference causal attribution process.

The Relationship Between Gender And Perceived Stress Levels In College Students, Meghan Gilbert

Symposium Of University Research and Creative Expression (SOURCE)

Previous research on stress in adults demonstrates that stress, even perceived stress, can take a toll on an individual’s health. Research also indicates that the severity of stress in college students has been rapidly increasing, which indicates a need for more investigation in this area. The purpose of this study was to determine if there was a difference between the stress levels of male and female college students and, if so, whether there is another factor involved that can account for this difference. The participants consisted of students attending Brigham Young University who were also active members of The Church …

Image Segmentation Using Fuzzy-Spatial Taxon Cut, Lauren Barghout

MODVIS Workshop

Images convey multiple meanings that depend on the context in which the viewer perceptually organizes the scene. This presents a problem for automated image segmentation, because it adds uncertainty to the process of selecting which objects to include or not include within a segment. I’ll discuss the implementation of a fuzzy-logic-natural-vision-processing engine that solves this problem by assuming the scene architecture prior to processing. The scene architecture, a standardized natural-scene-perception-taxonomy comprised of a hierarchy of nested spatial-taxons. Spatial-taxons are regions (pixel-sets) that are figure-like, in that they are perceived as having a contour, are either `thing-like', or a `group of …

‘Edge’ Integration Explains Contrast And Assimilation In A Gradient Lightness Illusion, Michael E. Rudd

MODVIS Workshop

In the ‘phantom’ illusion (Galmonte, Soranzo, Rudd, & Agostini, submitted), either an incremental or a decremental target, when surrounded by a luminance gradient, can to be made to appear as an increment or a decrement, depending on the gradient width. For wide gradients, incremental targets appear as increments and decremental targets appear as decrements. For narrow gradients, the reverse is true. Here, I model these phenomena with a two-stage neural lightness theory (Rudd, 2013, 2014) in which local steps in log luminance are first encoded by oriented spatial filters operating on a log-transformed version of the image; then the filter …

A Linearized Model For Flicker And Contrast Thresholds At Various Retinal Illuminances, Albert Ahumada, Andrew B. Watson

MODVIS Workshop

Watson and Ahumada (1992 SID) predicted flicker thresholds for bright displays using a temporal contrast sensitivity function (TCSF). Under the assumptions that the falling limb of the TCSF is linear at all retinal illuminations and that the Ferry-Porter law can be extended to supra-threshold levels, the thresholds for any of the three variables (frequency in Hz, log10 contrast, and retinal illuminance in log Trolands) can be predicted from the other two from a linear model with four parameters.

A Signal Detection Experiment With Limited Number Of Trials, Tadamasa Sawada

MODVIS Workshop

Signal detection theory has been well accepted in vision science to measure human sensitivity to stimuli in a Psychophysical experiment. The theory is formulated so that the measured sensitivity is independent from a response bias (criterion). The formulation is based on an assumption that number of trials in the experiment is infinite but this assumption cannot be satisfied in practice. The assumption came from two normal distributions used in the formulation. The distributions respectively represent a set of signal trial and that of noise trials in the experiment. In this study, I will show how the violation of the assumption …

Testing The Bayesian Confidence Hypothesis, Wei Ji Ma, Ronald Van Den Berg

MODVIS Workshop

Asking subjects to rate their confidence is one of the oldest procedures in psychophysics. Remarkably, quantitative models of confidence ratings have been scarce. The Bayesian confidence hypothesis (BCH) states that an observer’s confidence rating is monotonically related to the posterior probability of their choice. I will report tests of this hypothesis in two visual categorization tasks: one requiring rapid categorization of a single oriented stimulus, the other a deliberative judgment typically made by scientists, namely interpreting scatterplots. We find evidence against the Bayesian confidence hypothesis in both tasks.

A Conceptual Framework Of Computations In Mid-Level Vision, Jonas Kubilius, Johan Wagemans, Hans P. Op De Beeck

MODVIS Workshop

The goal of visual processing is to extract information necessary for a variety of tasks, such as grasping objects, navigating in scenes, and recognizing them. While ultimately these tasks might be carried out by separate processing pathways, they nonetheless share a common root in the early and intermediate visual areas. What representations should these areas develop in order to facilitate all of these higher-level tasks? Several distinct ideas have received empirical support in the literature so far: (i) boundary feature detection, such as edge, corner, and curved segment extraction; (ii) second-order feature detection, such as the difference in orientation or …

Metacognition: Using Confidence Ratings For Type 2 And Type 1 Roc Curves, S A. Klein

MODVIS Workshop

In the past five years there has been a surge of renewed interest in metacognition ("thinking about thinking"). The typical experiment involves a binary judgment followed by a multilevel confidence rating. It is a confusing topic because the rating could be made either on one's confidence in the binary response (standard rating Type 1 ROC) or on one's confidence sorted by whether the response was correct (Type 2 ROC). Both are metacognition. After a few remarks on challenging aspects of the Type 2 approach, I will present some interesting results for Type 1 ROC for both memory and vision research. …

Two Correspondence Problems Easier Than One, Aaron Michaux, Zygmunt Pizlo

MODVIS Workshop

Computer vision research rarely makes use of symmetry in stereo reconstruction despite its established importance in perceptual psychology. Such stereo reconstructions produce visually satisfying figures with precisely located points and lines, even when input images have low or moderate resolution. However, because few invariants exist, there are no known general approaches to solving symmetry correspondence on real images. The problem is significantly easier when combined with the binocular correspondence problem, because each correspondence problem provides strong non-overlapping constraints on the solution space. We demonstrate a system that leverages these constraints to produce accurate stereo models from pairs of binocular images …

Binocular 3d Motion Perception As Bayesian Inference, Martin Lages, Suzanne Heron

MODVIS Workshop

The human visual system encodes monocular motion and binocular disparity input before it is integrated into a single 3D percept. Here we propose a geometric-statistical model of human 3D motion perception that solves the aperture problem in 3D by assuming that (i) velocity constraints arise from inverse projection of local 2D velocity constraints in a binocular viewing geometry, (ii) noise from monocular motion and binocular disparity processing is independent, and (iii) slower motions are more likely to occur than faster ones. In two experiments we found that instantiation of this Bayesian model can explain perceived 3D line motion direction under …

Effects Of Medial Prefrontal Cortex Nmda Nr-1 Subunit Deletion In Adult Mice On Spatial Reference And Working Memory, Melissa Gorham, Dane Dewees

Scholars Week

Dysfunction of glutamate NMDA receptors may contribute to cognitive deficits in schizophrenia. In the present study, we examined the effects of chronic NMDA receptor dysfunction in the ventral medial prefrontal cortex (mPFC) on the acquisition of a spatial reference memory (SRM) and spatial working memory (SWM) radial maze task as employed by Niewoehner et al (2007). Localized NR1 gene deletions were induced in the ventral mPFC of floxed NR1 mice (DEL, n=10) using an AAV-Cre vector; control mice (CON, n=10) received sham deletions. In the SRM task, food was placed in 3 of 6 arms of an automated radial maze …

Identifying And Developing More Culturally Sensitive Diverse Leadership Measurement Prototypes, Joshua Thompson

Scholars Week

Chin and Trimble (2014) describe the need for a new culturally resonant model of leadership. A new model should present a more diverse and globally based perspective. Sixty-four characteristics of leadership were derived from both the current literature on leadership and from structured interviews and focus groups obtained from Western and non-Western samples. The current research is part of an ongoing study regarding cultural differences in what are believed to be the necessary characteristics of outstanding leadership. Participants included 90 students enrolled in a leadership courses at Western Washington University and Adelphi University. Participants completed an online survey in which …

Computational Modeling Of Depth-Ordering In Occlusion 
Through Accretion Or Deletion Of Texture, Harald Ruda, Gennady Livitz, Guillaume Riesen, Ennio Mingolla

MODVIS Workshop

Understanding the depth-ordering of surfaces in the natural world is one of the most fundamental operations of the primate visual system. Surfaces that undergo accretion or deletion (AD) of texture are always perceived to behind an adjacent surface.

An updated ForMotionOcclusion (FMO) model (Barnes & Mingolla, 2013) includes two streams for computing motion signals and boundary signals. The two streams generate depth percepts such that AD signals together with boundary signals generate a farther depth on the occluded side of the boundary. The model fits the classical data (Kaplan, 1969) as well as the observation that moving surfaces tend to …

Bayesian Modeling Of 3d Shape Inference From Line Drawings, Seha Kim, Jacob Feldman, Manish Singh

MODVIS Workshop

Human depth comparisons in line drawings reflect the underlying uncertainty of perceived 3D shape. We propose a Bayesian model that estimates the 3D shape from line drawings based on the local and non-local contour cues. This model estimates the posterior distribution over depth differences at two points on a line drawing. The likelihood is numerically computed by assuming a generative model, which generates random 3D surfaces and, via projection, random line drawings. The 3D surfaces are inflated from random skeletons and projected into line drawings. Given a novel line drawing, the model samples probable local surfaces based on the relations …

Formal Aspects Of Non-Rigid-Shape-From-Motion Perception, Vicky Froyen, Qasim Zaidi

MODVIS Workshop

Our world is full of objects that deform over time, for example animals, trees and clouds. Yet, the human visual system seems to readily disentangle object motions from non-rigid deformations, in order to categorize objects, recognize the nature of actions such as running or jumping, and even to infer intentions. A large body of experimental work has been devoted to extracting rigid structure from motion, but there is little experimental work on the perception of non-rigid 3-D shapes from motion (e.g. Jain, 2011). Similarly, until recently, almost all formal work had concentrated on the rigid case. In the last fifteen …

Appearance Controls Interpretation Of Orientation Flows For 3d Shape Estimation, Steven A. Cholewiak, Romain Vergne, Benjamin Kunsberg, Steven W. Zucker, Roland W. Fleming

MODVIS Workshop

The visual system can infer 3D shape from orientation flows arising from both texture and shading patterns. However, these two types of flows provide fundamentally different information about surface structure. Texture flows, when derived from distinct elements, mainly signal first-order features (surface slant), whereas shading flow orientations primarily relate to second-order surface properties (the change in surface slant).

The source of an image's structure is inherently ambiguous, it is therefore crucial for the brain to identify whether flow patterns originate from texture or shading to correctly infer shape from a 2D image. One possible approach would be to use 'surface …

Can Computational Models Of Shape Explain Object Perception?, Sp Arun, Rt Pramod

MODVIS Workshop

Despite advances in computation and machine learning, computers are still far behind humans in vision. This is most likely because humans use a sophisticated object representation which is very different from that used in computers today. Another challenge is that object representations in computer vision and human vision have not been systematically compared on the same objects. To address this issue, we measured perceptual dissimilarity between objects in humans in a visual search (taking search difficulty as an index of target-distracter similarity). We then compared these observed dissimilarities against the dissimilarity predicted by a large number of state-of-the-art computational models …
