The Role Of Eyewitness Confidence And Prosecution/Defense Presentation In How Facial Composites Shape Juror Decision-Making, Rebecca E. Singh

Student Theses

Eyewitness testimony has been found to be an unreliable form of evidence (Loftus, Miller & Burns, 1978; Oswald & Coleman, 2007; Wells & Hasel, 2007; Loftus & Greenspan, 2017; Jaross, 2018; Wade, Nash, & Lindsay, 2018; Wixted, Mickes, & Fisher, 2018). Yet, this evidence is still used in the courts today, and, in fact, is perceived by jurors as important and compelling in comparison to other case factors (e.g., character evidence, physical evidence; Topp-Manriquez, McQuiston, & Malpass, 2014; Kabzińska, 2015). Additionally, eyewitnesses are sometimes requested to help create a facial composite of the suspect and, critically, these composites are then …

The Effect Of Peer Collaboration On Kinematic Problem Solving, Alyssa Deronda

Seton Hall University Dissertations and Theses (ETDs)

Kinematic problems, a type of physics problem that involves object motion, pose a challenge for adults (Caramazza, McCloskey, & Green, 1981; Kozhevnikov, Motes, & Hegarty, 2007; McCloskey, 1983b; McCloskey, Washburn, & Felch, 1983). Adults often incorrectly predict the path of a moving object despite having prior experience with moving objects or formal physics education (Caramazza et al., 1981; Kaiser, Jonides, & Alexander, 1986). One way to improve kinematic problem solving may be through peer collaboration. Working together with a partner to solve a problem allows both people to help each other remember important parts of a complex problem and discuss …

Firearm Availability And Storage Practices Among Military Personnel Who Have Thought About Suicide, Craig J. Bryan, Annabelle O. Bryan, Michael D. Anestis, Lauren Khazem, Julia Harris, Alexis May, Cynthia Thomsen

Faculty Publications

More than 60% of US military suicides occur at home and involve a firearm. Nearly all military firearm suicides (95%) involve a personally owned firearm. Nonmilitary data indicate that the risk of suicide is 6 times higher in households with a firearm, although this risk may be reduced if the firearms are kept unloaded and/or locked. Because attempts using firearms have very high fatality rates, safe firearm storage practices could be an important component of comprehensive suicide prevention in the military. This study examined associations of firearm ownership and storage practices with suicidal thoughts and behaviors among military personnel.

Impact Baseline Composite Score Differences Among Student Athletes, Kerry Schutte

Electronic Theses and Dissertations

The ImPACT aims to measure neurocognitive functioning in student athletes. Many schools administer preseason ImPACT assessments to determine athletes’ baseline functioning. Follow-up ImPACT assessments are administered to athletes who sustain concussions to compare their pre- and post-injury functioning. Normative data may be used in place of individualized baseline scores if athletes were not administered baseline assessments. At the inception of this study, normative datasets consisted of scores from typically developing athletes. However, research suggests athletes of varying gender and exceptionality statuses perform differently on baseline ImPACT assessments. In particular, differences were found among male and female athletes as well as …

Exploring Innovation And Behavioral Flexibility In African Lions (Panthera Leo) And Snow Leopards (Panthera Uncia), Victoria L. O'Connor

Theses and Dissertations

Intelligence may have evolved to help animals problem-solve in their physical and/or social environments, which enables them to cope with changes in their environments. Humans can reduce wildlife conflict by understanding how species that face harsh environments assess a situation and alter their behavior. Tests for cognitive behavior aim to formulate clear behavioral criteria for inferring an animal’s mental processes. We designed a custom multi-access puzzle box (MAB) to present a simple and effective behavioral test for exploring innovation in two species, African lions (Panthera leo) and snow leopards (Panthera uncia). Despite being vastly underrepresented in …

Behavioral Hypervigilance In A Normative Population, Karly Weinreb

Theses and Dissertations

Hypervigilance is conceptualized as a symptom of trauma-related disorders, however it can also occur in a normative population. To distinguish normative hypervigilance from trauma-related hypervigilance, 372 participants (123 trauma-exposed and 249 non-trauma-exposed) completed a questionnaire assessing hypervigilance in contexts. Trauma-exposed participants reported greater levels of hypervigilance in 3 contexts.

Arousal And Anxiety Level Influences On Golf Putting Performance, Chloe Paulsen, Ryan M. Yoder

Honors Theses

Arousal levels can help and hinder performance in various sports and many athletes manipulate arousal levels during practice or competitions. Professional golfers typically putt in complete silence but studies have shown that stimulus can help performance. Twelve participants completed general and sport anxiety questionnaires before completing 3 golf putts at a target under 30 seconds with a music stimulus for each group. Music stimulus had an affect on the moderate arousal level groups showing the best performance with the slowest time to complete the putting task. This shows that putting may be performed better with moderate auditory arousal to produce …

Context And Regulation Of Homeschooling: Issues, Evidence, And Assessment Practices, Janet F. Carlson

Buros Center: Professional Staff Publications

The article discusses salient factors that influence the current context within which homeschooling occurs. Individual states have applied various approaches to establish regulations that both preserve the rights of homeschooling parents and fulfill the state’s obligation to ensure that its residents receive the education to which they are constitutionally entitled. Case and ethnographic studies or research involving small and selected samples often appear in outlets associated with homeschool advocacy groups or in outlets that are not mainstream. The paucity of empirical evidence derived from methodologically strong research paradigms has led to little certainty about many aspects of homeschooling including its …

Like Me, Do What I Say, & Think About My Influence: The Effects On Witness Choosing And Metacognition, Brittany Race

Graduate Theses and Dissertations

Confidence can be a strong predictor of accuracy if circumstances are ideal (Wixted & Wells, 2017), but ideal circumstances are not always present. As such it is important to understand ways to ameliorate potentially negative effects on eyewitness metacognition. Rapport building, though seen as an important element of police/witness interaction (Vallano et al., 2015), can lead to some potentially negative memory effects (Wright et al., 2015). Additionally steering, or the process of directing a witness toward a particular suspect, can increase false identifications. Recently the researcher has developed a paradigm meant to better calibrate confidence by reinstating the context of …

Functional Opponency In Working Memory Capacity Predicts Cognitive Flexibility In Problem Solving., Charles A. Van Stockum Jr.

Electronic Theses and Dissertations

Cognitive flexibility is a hallmark of individuals with higher working memory capacity (WMC). Yet, research demonstrates that higher WMC individuals are sometimes more likely to adopt rigid problem-solving approaches. The present research examines a novel account for these contradictory findings—that different WMC mechanisms interact in ways that both support and constrain cognitive flexibility. Across three studies, participants completed the water jug task—a problem-solving task requiring them to first establish and then break mental set using a complex strategy. Participants then completed measures targeting three WMC mechanisms: attention control, primary memory, and secondary memory. Study 1 demonstrated that primary memory and …

Disordered Eating, Depression, And Cognitive Vulnerabilities In College Women., Kelsea Visalli

Electronic Theses and Dissertations

This study tests a path model of disordered eating and symptoms of depression derived from the Hopelessness Theory of Depression (Abramson, Metalsky, & Alloy, 1989). The model proposes that cognitive vulnerabilities to depression will be associated with disordered eating behaviors and symptoms of depression in college women. A sample of undergraduate women (n = 181) completed self-report measures assessing disordered eating symptoms and symptoms of depression. Findings revealed that one, but not all, cognitive vulnerability was associated with disordered eating behavior, and that disordered eating behaviors and symptoms of depression are bi-directionally associated. Implications and future research directions are discussed.

Do Psychopathic Traits Influence Distractibility By Empathy-Eliciting Pictures?, Priya M. Reji

Student Theses

Empathy is a crucial component in forming interpersonal connections, and reflects the ability to share and understand the feelings of others. Psychopathy is often associated with a reduced ability to feel and display empathetic concern towards other people. The Response Modulation Hypothesis argues that such individuals have an attentional deficit, which makes it difficult for them to shift focus between stimuli, thus individuals who have high scores on the interpersonal-affective factor of psychopathy have an increased ability to ignore emotional stimuli that are goal-irrelevant. The current study investigated whether psychopathic traits would influence distractibility on an emotional Stroop (eStroop) task. …

Multiple Species Of Distinctiveness In Memory: Separating Task Distinctiveness From Statistical Distinctiveness, Matthew Robert Gretz

Master's Theses

Distinctiveness refers to the memorial benefit of processing unique or item-specific features of a memory set relative to a non-distinctive control. Traditional distinctiveness effects are accounted for based on qualitative differences in how distinctive items are encoded at the time of study. This thesis project aims to evaluate whether a different species of distinctiveness—statistical distinctiveness—may provide a separate contribution to memory beyond traditional encoding-based processes. Statistical distinctiveness refers to the relative frequency with which a specific memory item or set is processed. The current study evaluated statistical distinctiveness through a series of mixed groups in which DRM lists were studied …

Exploring The Moderating Effect Of Maternal Scaffolding On The Temperament - Language Development Relationship, Chelsea L. Robertson

Electronic Theses and Dissertations

Many studies have examined the relationship between a child’s temperament and its effect on his or her early language development. However, few studies have investigated the detrimental effects a child’s negative affectivity may have on their language development and potential ways these effects may be limited through parental behaviors. The current study aimed to investigate if physical or verbal maternal scaffolding behaviors moderated the effect negative affect has on language development. Although it was expected that maternal encouragement of physical activity would play a moderating role in the relationship between temperament and language development, no such relationship was found. One …

Understanding The Effect Of Font Type On Reading Comprehension/Memory Under Time-Constraints, Elizabeth Dressler

Theses/Capstones/Creative Projects

This research study investigated the effects that font type and amount of time had on the reading comprehension. It was predicted that students restricted with time and given difficult-to-read font (Haettenschweiler) would perform more poorly because more cognitive resources are being utilized to decode the typography compared to an easy-to-read font (Times New Roman). Consequently, there would be fewer cognitive resources available to comprehend and remember the material. Previous research has consistently shown that subjects perform better from reading or memorizing words in difficult-to-read font. However, almost all previous research has consisted of short passages, thereby limiting ecological validity. Results …

Language Access In Early And Late Spanish-English Bilinguals: An Erp Study, Lissete Gimenez-Arce

Student Theses

Research suggests that code-switching between two languages is possible because there is nonselective access to both languages, i.e., both languages are interdependent and stored in a shared lexicon. In this study, we used event-related brain potentials (ERPs) to measure the neural processes associated with language access, in particular, the ERP components: N200 and N400. Although previous studies have utilized these ERPs to investigate language access using interlingual homographs, i.e., words that look the same in two languages but have different meanings, these have focused on comparisons of monolingual and bilinguals. In contrast, we used a design that looked at Spanish …

How Does Alcohol Intoxication Impair Risk Detection Of Sexual Assault? Testing An Integration Of Alcohol Myopia And Social Information Processing Theories, Alexander James Melkonian

Graduate Theses and Dissertations

Sexual assault among young adults is a highly prevalent public health concern. Alcohol is often implicated as a risk factor for sexual assault through its impairing effects on an individual’s ability to process and respond to social cues in the environment. The effect of alcohol myopia can result in greater focus of attention on salient environmental cues. The relationship between alcohol intoxication and resulting behavior may depend on what type of information is most salient. The current study examined the effects of alcohol on social information processing as it relates to sexual assault risk detection. Method: Participants were 48 young …

Implicit Bias And The Boundaries Of Belief: A Single-Representational Dual-Attitude Account Of Implicit Attitudes, Austin Dakota Synoground

Graduate Theses and Dissertations

Since their inception, implicit attitudes have been defined as associative mental states, separate from beliefs, which are considered to be propositional in nature. Recently, several philosophers have challenged this distinction, arguing that implicit attitudes are actually unconscious beliefs. In turn, I argue that the attitudes detected by current experimental paradigms are blind to distinctions between implicit attitudes, which I define as the products of an associative learning mechanism, and unconscious beliefs, which are the products of a propositional learning mechanism. Specifically, I argue for a single-representational dual-attitude account of implicit bias.

Across Continents And Demographics, Unpredictable Maternal Signals Are Associated With Children's Cognitive Function, Elyssia Poggi Davis, Riikka Korja, Linnea Karlsson, Laura Glynn, Curt A. Sandman, Brian Vegetabile, Eeva-Leena Kataja, Saara Nolvi, Eija Sinervä, Juho Pelto, Hasse Karlsson, Hal S. Stern, Tallie Z. Baram

Psychology Faculty Articles and Research

Background

Early life experiences have persisting influence on brain function throughout life. Maternal signals constitute a primary source of early life experiences, and their quantity and quality during sensitive developmental periods exert enduring effects on cognitive function and emotional and social behaviors. Here we examined if, in addition to established qualitative dimensions of maternal behavior during her interactions with her infant and child, patterns of maternal signals may contribute to the maturation of children's executive functions. We focused primarily on effortful control, a potent predictor of mental health outcomes later in life.

The Influence Of Tropical Climate On Cognitive Task Performance And Aiming Accuracy In Young International Fencers, Nicolas Robin, Aurelie Collado, Stephane Sinnapah, Elisabeth Rosnet, Olivier Hue, Guillaume R. Coudevylle

Journal of Human Performance in Extreme Environments

This study examined how a tropical climate (TC) influences the cognitive and aiming task performances of young international fencers. The participants performed the tasks in TC and an air-conditioned room. In each session, they completed questionnaires evaluating affective states, fatigue, and comfort and thermal sensations. They also carried out cognitive tasks (simple and choice reaction time, attention, and vigilance tasks) and a motor task testing aiming accuracy with a sword while wearing protective clothing and a mask. TC, which was observed to decrease thermal discomfort, was revealed to decrease aiming accuracy and positive affective states. There was no deleterious effect …
