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 …

Naturalistic Clinical Decision Making By Emergency Department Staff And The Assignment Of Suicide Risk Categories Within An Urban Veteran Population., Gerd Naycock

Research Day

The ability to comprehensively and effectively identify those individuals who are at greatest risk to engage in self-directed violence (SDV) forms the cornerstone for all professional suicide prevention activities. To that end, mental health professionals have come to rely on the use of risk stratification to identify at-risk individuals as a way to inform and guide risk management and treatment, without having the benefit of empirical evidence to support such practices. The current program evaluation examined archival data comprised of suicide risk assessments conducted by mental health professionals on suicidal veterans (N = 1,560) in the emergency department of a …

Object Recognition And Visual Search With A Physiologically Grounded Model Of Visual Attention, Frederik Beuth, Fred H. Hamker

MODVIS Workshop

Visual attention models can explain a rich set of physiological data (Reynolds & Heeger, 2009, Neuron), but can rarely link these findings to real-world tasks. Here, we would like to narrow this gap with a novel, physiologically grounded model of visual attention by demonstrating its objects recognition abilities in noisy scenes.

To base the model on physiological data, we used a recently developed microcircuit model of visual attention (Beuth & Hamker, in revision, Vision Res) which explains a large set of attention experiments, e.g. biased competition, modulation of contrast response functions, tuning curves, and surround suppression. Objects are represented by …

Locke, Figure, And Judgement: A Consistent Answer To The Molyneux Problem, Jamale Nagi

Student Research Symposium

Ever since the early modern period the Molyneux Problem has been a topic of debate both in the philosophy of perception and the psychology of perception. The problem centers on whether the senses share representational content between one another, or does each sense modality have its own stock of representational content that becomes associated with the others after some habituation. For example, if you knew a shape only by touch, could you identify that shape when seeing it for the first time without being allowed to touch the object? Typically, rationalists have held to the former claiming yes, while empiricists …

Deception Detection In Clinical Interview, Olivia Preston, Melissa Lewis

Student Research Symposium

The objective of Forensic Assessment of Client Truthfulness (FACT) measure is to detect deception in forensic psychology consultations. A statistically significant tool using verbal content analysis was created, based a synthesis of previous research in the field. This presentation reviews the research project and highlights one phase of the study where ratings true and deceptive statements in cases of accused sex offenders or insanity defense claimants were compared. Multiple ANOVAs, t-tests, and factor analyses were conducted. When FACT scores were dichotomized, 86% of the ratings characterized the true statements as true, and 81% of the ratings categorized the false statements …

Direct Versus Indirect Assessment Of Truthfulness, Lauren Bowling, Olivia Preston, Bridgette Norris, Jennifer Gill, Shawn Johnston

Student Research Symposium

This study uses a verbal content analysis measure, the Forensic Assessment of Client Truthfulness (FACT), derived from the most empirically-supported measures in deception detection, Criteria-Based Content Analysis and Reality Monitoring. This study tests the accuracy of the indirect assessment of truthfulness (i.e. consideration of the FACT criteria, which are empirically-related to truthfulness) in comparison to direct assessment of truthfulness (i.e. subjective consideration of whether a statement is true or false). The FACT, an indirect measure, is employed along with a direct assessment of truthfulness to distinguish between true and false statements. The study contains four research conditions including the true …

Attributes Of True And False Statements Of Criminal Defendants, Camilla Cummings, Olivia Preston, Nicolette Wise, Shawn A. Johnston

Student Research Symposium

The research study uses a verbal content analysis measure, the Forensic Assessment of Client Truthfulness, derived from the most empirically-supported measures in deception detection (i.e. Criterion-Based Content Analysis and Reality Monitoring). This measure is employed in the study to distinguish between true and false statements in forensic psychological evaluations. The study contains four research conditions including the true and false statements of men accused of sex offenses and of men claiming an insanity defense. Using a repeated measures design, the four statements were rated by 127 university students. Using factor analyses, ANOVA analyses, and t-tests, the results showed that the …

The Pid-5 Does Not Contain Validity Scales. Do You Care?, Carisha Kelsey, David G. Fischer

Student Research Symposium

The most recent edition of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) provides clinicians with a new personality assessment tool, the Personality Inventory for DSM-5. It is one of a number of assessments provided for use “in research and evaluation as potentially useful tools to enhance clinical decision-making…” The PID-5 does not contain validity scales to assist clinicians in assessing personality and making diagnostic decisions. This research project seeks to answer the question, “Can the PID-5 be a useful tool without a set of validity scales provided to assist in the interpretation of results?” A literature …

The Effect Of Stereoscopic (3d) Movies On Psychological And Physiological Experiences, Dawn M. Sarno

Honors Program Theses and Projects

Despite the recent rise in the popularity of 3D entertainment technology, there is surprisingly little research on the psychophysiological experience of watching 3D movies. Previous studies suggest that exposure to stereoscopic (3D) images in training environments (e.g., flight simulators) can cause discomforts including eyestrain and visually induced motion sickness. However, existing research on 3D entertainment has been mixed and has relied primarily on retrospective, non-experimental research designs, which do not allow us to draw clear causal conclusions. The purpose of this study was to examine the psychological and physiological effects of viewing 3D movies using a controlled, manipulated experiment. Eighty-two …

Stigma-By-Association: The Effect Of Parent Disengagement On Head Start Teacher Attitudes Toward Their Students, Rachael Antonette Levine

Theses and Dissertations

This study sought to examine the relationship between parents, teachers, and teacher perceptions of students in a Head Start setting. Specifically, this study explored the impact of parent engagement on teacher perceptions for student kindergarten readiness. Head Start operates under the goal of involving the entire family, suggesting that parent involvement, or engagement, is beneficial for the student. This also suggests that a lack of involvement may be detrimental. Following social psychology theories examining stigma, and stigma-by-association, this student attempted to determine whether parent disengagement from the childâ??s education is a stigmatizing factor, and if that stigma carried over to …

The Ontario Domestic Assault Risk Assessment (Odara): A Validation And Comparison Study For An Oregonian Law Enforcement Agency, Jennifer C. Ulmer

Doctor of Psychology (PsyD)

The predictive validity of intimate partner violence (IPV) risk measures continues to be a newer, but significant, area of research within the domain of violence risk assessment. This study describes local (Oregon) normative data for the ODARA (IPV risk measure) as well as investigate, for a specific law enforcement agency, which tool is a superior predictor for the agency, a general violence risk assessment tool, i.e., the LS-CMI (part one), or an IPV-specific risk tool, i.e., the ODARA. Archival data was obtained through a law enforcement agency’s research department. Descriptive and comparative analysis was done for the ODARA and LS/CMI …

The Short And Long-Term Effects Of Chronic Ketamine During Adolescence On Object Recognition Memory In Rats, William Hardin

Seton Hall University Dissertations and Theses (ETDs)

Prior research has demonstrated that ketamine causes deficits in object recognition and location memory following both acute and chronic administration (Pitsikas & Boultadakis, 2009; Venãncio et al., 2011). Although it is well established that abuse of many different kinds of drugs during the critical developmental period of adolescence can lead to impairments in cognition later in adulthood (Gilpin et al., 2012; Wagner et al., 2010), no research has investigated the effects of chronic ketamine administration during adolescence and its effects on behavior in adulthood. With recent research establishing that chronic ketamine during adolescence produces late-onset alterations in electrophysiology during adulthood …

Retention Across Pedagogies, Rachel Larkin

Senior Honors Projects, 2010-2019

When teaching, many professors try to increase their students’ retention of the information that is taught. Instructors can incorporate active learning, repeated testing, collaborative testing, and/or corrective feedback into traditional forms of teaching (e.g., lecture), or they can combine all of these components and transform their entire course, such as with Team-Based Learning (TBL). The current study compares retention of course material in TBL, lecture, reading, and control conditions in a lab setting. In the first session, students received one teaching method and learned about an article on whether having pets led to lowered blood pressure. During the second session, …

Helicopter Parenting And Parent-Child Attachment, Kaitlin S. Fitzgerald

Senior Honors Projects, 2010-2019

Helicopter parenting is the colloquial term that refers to a unique patterning of parenting dimensions that result in a style both high in behavioral control and levels of warmth and support, and low in autonomy-granting (Padilla-Walker & Nelson, 2012). Parental attachment–distinct from helicopter parenting–typically involves the initial relationship between parent and child which affects the child’s overall life satisfaction and well-being (mainly in areas associated with relationships, motivation, and health-related behaviors). Despite what areas may overlap between parent-child attachment and helicopter parenting, little research has been done on the relation among these variables. The current study examined the associations among …

The Effect Of Auditory Stimuli On Visual Time-To-Contact Perception, Chelsea L. Rugel

Senior Honors Projects, 2010-2019

Previous research has demonstrated that auditory and visual stimuli have individual effects on the accuracy of a person’s estimation of time-to-contact (TTC), the time at which two objects collide. Prior findings also suggest that there is cross-modal interference between vision and audition; however, this phenomenon has never been studied in a TTC situation. (Driver & Spence, 1998; Ichikawa & Masskura, 2006; Roseboom, Kawabe, & Nishida, 2013) In this study we attempted to fill in this research gap by examining the effect of auditory speed cues over visual speed cues in a two-dimensional TTC scenario, and by determining if an object’s …

The Effects Of X-Axis Rotation On Data Estimation Accuracy, Catherine Mathers

Senior Honors Projects, 2010-2019

Researchers, pollsters, marketers, and others use graphical displays to reduce the need for wordy, and often unclear, descriptions of their findings. Numerous studies have attempted to determine important graphical attributes that aid readers’ graphical perception. For example, does three-dimensionality (3D) of a graph help readers to accurately assess the graph’s data? The present study is the first to use eye movement data to quantify how 3D graphs, graph type, the use of gridlines, and data positioning affected readers’ perception and accuracy. Participants viewed 24 different graphs while their eye movements were recorded. Time, fixation, and accuracy were recorded for each …

Can Small Details Bring Big Success? Construal Levels As Academic Goal Strategies, Christopher R. Deitrick

Senior Honors Projects, 2010-2019

One avenue to help students reach educational goals is implementation intentions, a tool encouraging

planning the “when, where, and how” of goal-oriented actions (Gollwitzer, 1999). However,

implementation intentions need validating outside of the laboratory (Gollwitzer & Sheeran, 2006). To

help do so, they can be viewed through Construal-Level Theory (CLT), which explains why we may have

trouble setting intentions before we can fulfill them (Trope & Liberman 2010). A study was conducted

wherein 56 participants from a section of PSYC 330 either wrote about their college study habits or

completed implementation intentions preparing them to study for an upcoming exam. …

The Relation Of Service Activity To Change In Empathy, Nancy L.C. Windsor

Senior Honors Projects, 2010-2019

The purpose of this study was to explore the relationship between empathy, service, and other variables that have been seen in the past to be possible predictors of empathy and service. Undergraduate and graduate students took a survey measuring their emotional empathy, strength of religious faith, intent to engage in civic action, other predictor variables, and the amount of service each participant engaged in. Pearson’s correlations and independent t tests were run to analyze the relationships between the variables. The intent to engage in civic action measure was highly correlated with both the emotional empathy scale and strength of religious …

The Effects Of In-Class Application Questions On Academic Behaviors, Julia Ricotta

Senior Honors Projects, 2010-2019

Interteaching is a behavioral method of teaching college co urses, where students take a more active approach to learning. The current study manipulated int erteaching preparation guides and studied the effects on exam scores, attendance, duration of discussion, and ratings of the discussions. Both groups received the same materials in di fferent formats. The control group completed full prep guides at home, which included factual an d application questions. The intervention group completed revised prep guides at home, whi ch included factual questions, and application questions in class. During discussions, the control group discussed answers to the full prep guides, …

Delay And Probabilistic Discounting Of Alcoholic Beverages, Frank L. Galante

Senior Honors Projects, 2010-2019

Discounting tasks were used to determine the degree to which college undergraduates discounted delayed and probabilistic alcoholic beverages. Tasks were framed in terms of gains (i.e.,obtaining a hypothetical amount of alcohol) and losses (i.e., losing a hypothetical amount of alcohol). In all gain and loss conditions, discounting was evident and was generally well described by a hyperboloid function. Gains were discounted more steeply then losses. There were no correlations between the median delay gain discounting rates and the median delay loss discounting rates. Likewise, there were no correlations between the median probabilistic gain discounting rates and the median probabilistic loss …

The Effect Of Communication Type On Knowledge Retention Of Brain Injuries, Alyson Cregger

Senior Honors Projects, 2010-2019

Misconceptions about traumatic brain injuries have been seen in the general population since 1988. Previous research has demonstrated that the misconceptions are not limited to geographical area and have been seen in health care professionals. A possible explanation for these misconceptions could be the ineffective transmission of knowledge. The current study examined the effect of an educational intervention on eight misconceptions and their ‘real life’ applications, as well as the general knowledge surrounding traumatic brain injuries. Comparative and absolute risk were also examined. Thirty undergraduate students were given a pre-test consisting of four surveys (misconceptions, application of misconception, general knowledge, …

The Impact Of “Fearful” And “Serene” Mood On Mortality Salience, Kathryn A. Howard

Senior Honors Projects, 2010-2019

Seventy-eight participants were randomly assigned to receive either a serene, neutral, or fearful mood induction, followed by either a neutral salience or mortality salience induction. After these manipulations, participants read a political essay that opposed their world view. Participants then completed several measures examining how much they liked/did not like the author of the essay, along with a measure assessing their opinion on an ethnic out-group. It was hypothesized that participants who received the serene mood induction would derogate the author of the opposing essay and ethnic out-group members significantly less than those who received the fearful or neutral mood …

The Effect Of Global And Local Processing In The Attentional Blink, Ashley Kalavritinos

Senior Honors Projects, 2010-2019

The attentional blink (AB) is an individual’s inability to perceive the second of two targets presented in a rapid serial visual presentation (RSVP). The constructs of global and local attention have been a principle concern in modern psychology. The perception of an object as an overall form is referred to as the global aspect, while the separate parts compose the local aspect. The purpose of this study was to explore whether the following factors affect the characteristics of an individual’s AB: (1) When target one (T1) and target two (T2) were the same or different letters (2) Whether T1 was …

Judging Laura, Rebecca E. Richardson

Senior Honors Projects, 2010-2019

Laura Audax is a sixteen-year-old girl who has an interesting set of characteristics. She is a dynamic mixture of compassion, stubbornness, brilliance, recklessness, imagination, and arrogance. The way the world understands these personality traits has transformed and evolved over time. If a girl like Laura lived in four different time periods, society would react differently to her in each era, but the overall question is how different these reactions really are. Does the definition of what makes certain personality traits “good” or “bad” change over time?

The following four stories take place in 1850, 1920, 2015, and 2100 respectively, and …

Contingency Management And Alcohol Abuse, Amanda D. Walker

Senior Honors Projects, 2010-2019

This paper explores a substance abuse intervention strategy known as contingency management (CM), which has been shown to be effective in a variety of contexts (Prendergast, 2006). Specifically, it identifies the minimum hypothetical amount of money participants might be willing to exchange for their abstinence from alcohol on a given day of the week. The hypothetical amounts of money were identified using the Walker Alcohol Contingency Test (WACT), and participants’ risk level for alcohol consumption was identified using the Alcohol Use Disorders Identification Test (AUDIT), which grouped participants into one of three caregories. Additional information such as year in school …

The Effectiveness Of Social Stories On Children With Autism Spectrum Disorder: A Literature Review, Caroline E. Johnson

Senior Honors Projects, 2010-2019

The primary goal of Social Stories is to address debilitating difficulties and are written with the goal of objectively sharing important social information with individuals with ASD (Gray, 1998). The purpose of this literature review was to look at the effectiveness of Social Stories on children with autism.
