Exploring Age-Related Metamemory Differences Using Modified Brier Scores And Hierarchical Clustering, Chelsea Parlett

Computational and Data Sciences (MS) Theses

Older adults (OAs) typically experience memory failures as they age. However, with some exceptions, studies of OAs’ ability to assess their own memory functions– Metamemory (MM)– find little evidence that this function is susceptible to age-related decline. Our study examines OAs’ and young adults’ (YAs) MM performance and strategy use. Groups of YAs (N = 138) and OAs (N = 79) performed a MM task that required participants to place bets on how likely they were to remember words in a list. Our analytical approach includes hierarchical clustering, and we introduce a new measure of MM—the modified Brier—in order to …

Quantitative Reasoning: Individual Differences In Heart Rate And Response Latency, Abigail L. Van Nuland

Graduate Theses/Dissertations

Math is something that all students are required to use at some point during their academic careers. Then they must use it again in the real world. Unfortunately, many students struggle with quantitative processing. In the current study, participants answered first grade level math problems in order to assess cognitive effort when solving math problem. Participants were then assigned randomly to one of two conditions; Answer or Equation. In the Answer Condition participants were asked to solve a series of math problems, whereby they were given a math equation and then they were asked to choose an answer. In the …

Can Goal-Setting Improve Hospital Volunteers’ Intrinsic Motivation?, Genesis Orellana

Ursidae: The Undergraduate Research Journal at the University of Northern Colorado

With the objective of increasing volunteer retention, hospital administrators are interested in fostering volunteers’ motivation to continue working in the departments in which they have been placed. However, there is limited research on hospital volunteers’ motivation and whether setting goals affect their motivation. The purpose of my research was to examine whether hospital volunteers who set personal goals would increase their intrinsic motivation and tenure at a particular site. My research questions were: “Is there an effect on intrinsic motivation from a goal-setting intervention in hospital volunteers?” and “Will a goal-setting intervention help hospital volunteers set stronger goals?” Eight volunteer …

Recovering Depth From Stereo Without Using Any Oculomotor Information, Tadamasa Sawada

MODVIS Workshop

The human visual system uses binocular disparity to perceive depth within 3D scenes. It is commonly assumed that the visual system needs oculomotor information about the relative orientation of the two eyes to perceive depth on the basis of binocular disparity. The necessary oculomotor information can be obtained from an efference copy of the oculomotor signals, or from a 2D distribution of the vertical disparity, specifically, from the vertical component of binocular disparity. It is known that oculomotor information from the efference copy and from the vertical disparity distribution can affect the perception of depth based on binocular disparity. But, …

Coupled Correlates Of Attention And Consciousness, Ravi Varkki Chacko

McKelvey School of Engineering Graduate Student Theses & Dissertations

Introduction: Brain Computer Interfaces (BCIs) have been shown to restore lost motor function that occurs in stroke using electrophysiological signals. However, little evidence exists for the use of BCIs to restore non-motor stroke deficits, such as the attention deficits seen in hemineglect. Attention is a cognitive function that selects objects or ideas for further neural processing, presumably to facilitate optimal behavior. Developing BCIs for attention is different from developing motor BCIs because attention networks in the brain are more distributed and associative than motor networks. For example, hemineglect patients have reduced levels of arousal, which exacerbates their attentional deficits. More …

It Is In The Cards: An Analysis Of Greeting Card Selection Through Identity And Personality, Emily Topilow

Honors Projects

In this exploratory study, personal and social identity were analyzed for their effect on how consumers choose greeting cards. Factors, including personality, relationships, and identity will be qualitatively analyzed to understand people’s buying habits. Certain factors, including gender, personality, relationships, type of card, and frequency of receiving and giving cards, will be qualitatively analyzed for frequency. The two theories analyzed were the Social Identity Theory (SIT) and the Identity Theory (IT).

525 college-aged students were surveyed to examine their purchasing habits of greeting cards. The results showed that the identity of the card giver and the identity of the card …

An Erp Investigation Of Reward Signals For Differing Classes Of Reinforcing Stimuli, Darin R. Brown

Psychology ETDs

In order to successfully traverse an actively complex environment, an agent is required to learn from the consequences of their actions. For over a century, models of behavior have been developed demonstrating these consequence-based learning systems. More recently, underlying biological systems have been found to adhere to these constructs of learning. The electroencephalographic signal known as the Reward Positivity (RewP) is thought to reflect a dopamine-dependent cortical signal specific to reward receipt. Importantly, this signal has been shown to adhere to an axiomatic (rule-like) positive reward prediction error, whereby it is evoked following outcomes that are better than expected. These …

Effects Of Perceived Audiences On Discrimination Learning In Pigeons ( Columbia Livia ), Peyton M. Mueller, Matthew Murphy

Honors Theses

The social facilitation effect is a phenomenon frequently discussed in the subfield of social psychology. Some studies have examined the social facilitation or inhibition effects in nonhuman animals, though few have examined the effect of perceived audiences on their cognitive functioning. In order to study this effect, three different video stimuli were presented to one subject while solving a memorization discrimination task. It was hypothesized that the pigeon would learn a task at different rates based on the type of perceived audience presented. No significant results were found due to the fact that the subject was unable to learn the …

The Mechanism Of Directed Forgetting In Visual Working Memory, Katherine Camille Moen

LSU Doctoral Dissertations

The goal of the current study was to determine if forgetting in visual working memory (VWM) depends on the strength of the memory representations, and to examine different potential mechanisms of directed forgetting in VWM. The strength of memory representations varies depending on factors during encoding and maintenance, which may impact the likelihood of successful forgetting. Experiment 1 manipulated encoding time and cue onset, and utilized eye tracking in order to determine the extent of directed forgetting in VWM. Results support evidence for partial forgetting, and revealed that the strength of memory representations does not impact the likelihood of successful …

The Unfolding Argument: Why Iit And Other Causal Structure Theories Cannot Explain Consciousness, Adrian Doerig, Aaron Schurger, Kathryn Hess, Michael H. Herzog

Psychology Faculty Articles and Research

How can we explain consciousness? This question has become a vibrant topic of neuroscience research in recent decades. A large body of empirical results has been accumulated, and many theories have been proposed. Certain theories suggest that consciousness should be explained in terms of brain functions, such as accessing information in a global workspace, applying higher order to lower order representations, or predictive coding. These functions could be realized by a variety of patterns of brain connectivity. Other theories, such as Information Integration Theory (IIT) and Recurrent Processing Theory (RPT), identify causal structure with consciousness. For example, according to …

Imagining A Memory Palace: Method Of Loci And The Effect Of Object And Spatial Imagery Skill, Louis Varilias

Seton Hall University Dissertations and Theses (ETDs)

The method of loci is an ancient mnemonic technique. It involves imagining information to be remembered in a visual form, mentally placing those items into an imagined environment, and then mentally traveling within this environment to recall the information. Numerous studies have found that this method is robust and powerful, especially when compared to other mnemonic techniques like verbal rehearsal. Neuroimaging studies have found that using the method of loci recruits regions of the brain that involve spatial processing and episodic memory. However, little research has been done to examine the effects of individual imagery skill when using the method …

The Effects Of Counterfactual Priming On Belief In Fake News, Sean Bogart

Seton Hall University Dissertations and Theses (ETDs)

Fake news overwhelmed social media platforms, like Twitter and Facebook, during the 2016 U.S. presidential election. This new, digital brand of fake news that can be spread much more rapidly than older forms, is coupled with a lack of academic research into its effects, the reasons that certain individuals trust its veracity, and methods of decreasing overall belief in fake news. Confirmation bias is one of several reasons why individuals fall victim to fake news; although there are a few strategies that can be used to combat the negative effects of confirmation bias; counterfactual reasoning is one that has demonstrated …

The Effects Of Timbre On Perceptual Grouping In A Melodic Sequence, Thomas Rohaly

Masters Theses, 2010-2019

The current investigation sought to examine the effects of timbre on perceptual grouping in melodic sequences. While past research has shown that timbre shifts influence listeners’ pitch perception on a note-to-note basis (e.g., see Pitt, 2004; Russo & Thompson, 2005, & Creel, Newport, & Aslin, 2004), the current investigation extended this to timbre’s influence on pitch perception in the context of a melodic phrase. In Experiment 1, participants were presented with melodic sequences, made of sawtooth-like waves. Sequences, consisting of 6 tones, were followed by a target tone that had a static, dull, or bright timbre shift through the use …

Increasing Adult's Awareness Of The Importance Of End-Of-Life Care Discussions, Taylor Gardner

Capstone Projects and Master's Theses

For many American families, end-of-life care is often not discussed, until advanced illness or injury has fully disrupted everyday life. There are many benefits to discussing end-of-life care prior to any medical complications. Research has shown that individuals who plan their end-of-life processes with a hospice service provider and family members report a higher quality of death than individuals receiving common health care during their final six months of life. In order to make families and friends more comfortable with end-of-life discussions, I will conduct two one-hour educational sessions to students at California State University, Monterey Bay.

Contagious Or Not Contagious: Is That The Question? Evaluating The Effects Of Disease Contagion On Memory For Word Lists, Laura Pazos

Honors Theses

Researchers have suggested that individuals possess a disease-avoidance system designed to detect and remember potential sources of harmful pathogens, a system termed the behavioral immune system. Recently, Fernandes, Pandeirada, Soares, and Nairne (2017) reported an increase in memory for objects associated with individuals that are contaminated with a disease. My thesis extends this finding by examining whether disease-related memory benefits are due to the mere presence of a disease or whether the disease needs to be perceived as contagious and thereby threatening to facilitate memory. Two experiments, one between- and one within-subjects, were designed to test memory performance in the …

Music, Language, And Rhythmic Timing, Rhimmon Simchy-Gross

Graduate Theses and Dissertations

Neural, perceptual, and cognitive oscillations synchronize with rhythmic events in both speech (Luo & Poeppel, 2007) and music (Snyder & Large, 2005). This synchronization decreases perceptual thresholds to temporally predictable events (Lawrance et al., 2014), improves task performance (Ellis & Jones, 2010), and enables speech intelligibility (Peelle & Davis, 2012). Despite implications of music-language transfer effects for improving language outcomes (Gordon et al., 2015), proposals that shared neural and cognitive resources underlie music and speech rhythm perception (e.g., Tierney & Kraus, 2014) are not yet substantiated. The present research aimed to explore this potential overlap by testing whether music-induced oscillations …

Familiarization Through Ambient Images Alone, Nia Imani Gipson

Graduate Theses and Dissertations

The term “ambient images” has begun to show up in much of the current literature on facial recognition. Ambient images refer to naturally occurring views of a face that captures the idiosyncratic ways in which a target face may vary (Ritchie & Burton, 2017). Much of the literature on ambient images have concluded that exposing people to ambient images of a target face can lead to improved facial recognition for that target face. Some studies have even suggested that familiarity is the result of increased exposure to ambient images of a target face (Burton, Kramer, Ritchie, & Jenkins, 2016). The …

Differentiating Cognitive Deficits Between Adhd And In Utero Polysubstance Exposure, Dylan J. Seitz

Doctor of Psychology (PsyD)

ADHD is the most prevalent psychiatric disorder in children, affecting their executive and overall well-being as a result (Barkley, 2014; Shaw, Gogtay, & Rapoport, 2010). A rampant increase in new diagnoses of ADHD suggests the potential for misdiagnosis. Stimulants are the first line of treatment and associated with a number of deleterious long-term consequences for those misdiagnosed (Urban & Gao, 2014a). This is of particular concern for children prenatally exposed to substances as in utero use acts on similar neural mechanisms impacted by ADHD – leaving the children vulnerable to misdiagnosis and contraindicated intervention (Derauf, Kekatpure, Neyzi, Lester, & Kosofsky, …

Serial Neuropsychological Assessment Toward A Reliable Concussion Protocol, Daniel J. Soden

Doctor of Psychology (PsyD)

With more than 10,000 Sports Related Concussions (SRCs) per year at the collegiate level, interdisciplinary teams are often tasked with determining when an athlete may return to activity (Zuckerman et al., 2015). Due to neurochemical changes following an SRC, athletes are vulnerable to further injury if they suffer another head injury before given appropriate time to heal (Giza & Hovda, 2014). Cognitive testing is routinely utilized to detect the presence of cognitive dysfunction and aid in individualized treatment planning. Because athletes often demonstrate practice effects when retested, it is difficult to distinguish if the athlete is demonstrating cognitive dysfunction. Reliable …
