The Relationship Between Auditory Working Memory And Statistical Learning In Infancy, Mckenzie Mullins Sheets

Masters Theses

Although previous research indicates that there is a strong relationship between auditory working memory and language skills in children and adults, no studies have explored this relationship in infancy. Working memory develops shortly before the onset of many language abilities in infancy, including the ability to use statistical information to segment words from speech. To track frequent syllable co-occurrences within a speech stream to locate word boundaries, infants must hold auditory information in their mind as one syllable quickly displaces another. Thus, it seems likely that auditory working memory plays a role in statistical learning. In the current study, I …

Investigating The Transfer Of Learning, Psychological, And Neural Effects In Immersive Virtual Reality, Logan Taylor Markwell

Doctoral Dissertations

Achieving mastery or expertise requires a substantial amount of quality practice. Recent technological developments have introduced a novel approach to practice, virtual reality. Specifically, virtual reality offers a low-cost, customizable opportunity to practice while minimizing the risk of the individual. Given that some types of practice may not lead to the acquisition of a motor skill, or worse, lead to detriments of that skill, understanding the developing science of motor behavior in relation to virtual reality is imperative. The following literature review will begin with a brief historical account of the evolution of virtual reality. Next, some terms of virtual …

Investigating The Proposed Mechanisms Guiding Negative Attentional Templates, Michael Kevin Mugno

Masters Theses

To complete goal-directed visual search, information that is gathered in working memory must be sorted by relevancy to the current task. In order to bias search, attentional templates are created within the construct of visual working memory (VWM) using both endogenous and exogenous information. While most attentional templates are built around positive information, which is directly relevant to the target of search, there are cases where negative information, which is directly relevant to the search but not necessarily the target itself, may be more efficient. However, the mechanisms behind how these negative templates direct search is debated. The goal of …

Visual Working Memory Encoding And Action: An Investigation Using Fnirs And Mouse-Tracking, Kaleb Thomas Kinder

Doctoral Dissertations

Visual working memory (VWM) guides the motor system by temporarily keeping relevant information in mind. As an interface between perception and action, VWM plays a critical role in supporting goal-directed behavior. Research on the relationship between VWM and action has primarily focused on the effect of VWM on motor output. Traditional approaches index outcome responses, such as accuracy, but this practice provides limited information on underlying VWM processes. Conversely, the influence of action on VWM processes has received less attention and its neural correlates are not well understood. In this thesis, I examined VWM-action links using functional near-infrared spectroscopy (fNIRS) …

Neural Correlates Of Individuation And Subordinate-Level Categorization Of Other-Race Faces In Infancy, Kelly Roth

Doctoral Dissertations

Perceptual narrowing is a domain-general process in which infants move from a broad sensitivity to a wide range of stimuli to developing expertise within often experienced native stimuli (Maurer & Werker, 2014). One outcome of this is the own-race bias, characterized by an increasing difficulty in discriminating other-race faces with age and experience for those raised in a racially homogenous environment (Anzures, Quinn, Pascalis, Slater, Tanaka, & Lee, 2013). Recent theorists have proposed that this is due to a categorization-individuation process, wherein infants begin to categorize non-native stimuli, such as other-species’ faces, but individuate native stimuli, such as often-experienced human …

Tracking Flanker Task Dynamics: Evidence For Continuous Attentional Selectivity, Cody A. Levi, Katherine Peterson, Kaleb Kinder, Caglar Tas, Aaron Buss

Psychology Publications and Other Works

A central research goal in the cognitive sciences has been to understand the processes that underlie selective attention, or the ability to focus on goal-relevant information. Two opposing theories have been proposed in an effort to explain how selective attention emerges: one suggests that attention improves continuously over time, whereas the other proposes that attention improves at a discrete time point. While outcome-based data (e.g., reaction time) have successfully provided evidence for both accounts, there has been no empirical evidence to differentiate them. In this study, we used mouse-tracking in a flanker task that provided time sensitive measures associated with …

The Effects Of Relationships On Ans Function And Wellness, Olivia M. Maples

EURēCA: Exhibition of Undergraduate Research and Creative Achievement

The quality of relationships and social networks plays a vital role on well-being (Feeney & Collins, 2015). Social support is linked to positive biological profiles in that social support protects against the negative effects of changes in cardiovascular, neuroendocrine, and immune function. Furthermore, when exploring Autonomic Nervous System (ANS) function, higher heart rate variability has been shown to reflect a psychophysiological state compatible with social interaction (Quintana, Guastella, Outhred, Hickie, & Kemp, 2012). Social support has been shown to buffer against the negative effects of life stressors (Cohen & Wills, 1985), and ultimately, mortality (Holt-Lunstad, Smith, & Layton, 2010). In …

The Effects Of Stress And Anxiety On A Cued Attention Task, Catalina L. Gonzalez

EURēCA: Exhibition of Undergraduate Research and Creative Achievement

Previous research has shown visual attention tasks like the Infant Orienting With Attention (IOWA) Task are effective in identifying individual differences in spatial attention (Ross-Sheehy et al., 2015). Given visual attention is influenced by factors like stress/anxiety (Grillon et al, 2016) it may be possible to use attention tasks to identify participants high in stress and/or anxiety. Fifty-four adults completed a modified version of the IOWA task. Participants then completed the Perceived Stress Scale and Beck Anxiety Inventory, and were divided into three groups: Low_Stress/Low_Anxiety (LSLA), High_Stress/Low_Anxiety (HSLA), and High_Stress/High_Anxiety (HSHA). A Condition x Stress Group ANOVA revealed only a …

The Effect Of Familiarity On Learning With Video Clips Containing Seductive Details, Jonah Lee Ruddy

Doctoral Dissertations

Seductive information included in educational lessons can arouse students’ emotional and situational interest. However, research on seductive details across instructional modalities shows both helpful and harmful effects on learning. The seductive details effect describes the negative influence of interesting, but irrelevant, information on achieving learning goals. Results from studies of videos with relevant and seductive details in multimedia lessons are inconclusive. Prior knowledge of target information has been shown to moderate the seductive details effect. In this study, the moderating effect of prior exposure to, or familiarity with, seductive, rather than target, information was explored using a multifactorial design. The …

Executive Functioning Abilities And Social Competence In Undergraduates, Megan Carl

Doctoral Dissertations

Despite separate literatures linking attention-deficit/hyperactivity disorder (ADHD) symptoms and executive functions to social competence, no study has examined the simultaneous relationship of these two processes in adults. Beauchamp and Anderson (2010) propose the Socio-Cognitive Integration of Abilities (SOCIAL) model a biopsychosocial model as an explanation for the development of social competence. Given the patterns of social and neurological development in ADHD, it may be consistent with the SOCIAL model. Subcomponents of Beauchamp and Anderson’s (2010) SOCIAL model were utilized to examine the extent to which attention-deficit/hyperactivity disorder (ADHD) symptom severity moderated the relationship between executive function (EF) and social competence …

Generalizing Across Speaker And Gender During Early Word Learning: Evidence From A Statistical Learning Paradigm, Madison Newsom

EURēCA: Exhibition of Undergraduate Research and Creative Achievement

Before children can speak, they can track the likelihood that two syllables co-occur to pull words out of a continuous stream of speech. Previous research with 17-month-olds has suggested that words that have high co-occurrence statistics (i.e., high transitional probability, HTP) make better object labels than words with low transitional probability (LTP). Here we test whether infants can generalize the patterns tracked in a continuous stream of speech to a novel speaker and gender. Infants are familiarized with an Italian corpus produced by a female speaker, that contains both HTP and LTP words. Following familiarization, infants are trained to pair …

Infant Object Recognition: Two- And Three-Dimensional Visual Processing, Alexandra Chelsea Romano

Masters Theses

Visual attention and recognition memory in infancy are highly dependent on the type of stimulus the infant is familiarized to and the conditions of familiarization. For example, in studies that initially exposed infants to test stimuli in laboratory settings (e.g., Courchesne, Ganz, & Norcia, 1981; Reynolds & Richards, 2005), the Negative Central (Nc) event-related potential (ERP) component associated with infant visual attention has shown greater amplitude for novel compared to familiar stimuli. Conversely, when initial stimulus exposure occured outside of the laboratory and the stimulus was highly familiar, studies have shown greater amplitude Nc to familiar compared to novel stimuli …

Examining The Effects Of Frustration On Working Memory Capacity In An Emerging Adult Sample, Jonathan Parks Fillauer

Masters Theses

Attention-Deficit/Hyperactivity Disorder (ADHD) is associated with numerous pejorative outcomes in adults such as low frustration tolerance and deficits in central executive functioning. The present study aims to examine (1) the effect of induced frustration on working memory capacity (WMC) and (2) the unique contribution of ADHD symptoms and other commonly comorbid disorders (i.e., anxiety/depression and alcohol use) to frustration. Participants (N=66) were randomly assigned to either the control group (n=32) or the experimental group (n=34). The Frustration Induction Procedure (FIP) was administered to participants in the experimental group and a neutral, non-frustrating task was administered to a control group. A …

How Short Term Mindfulness Training Affects Emotion Regulation On College Students, Holly E. Flatt, Andrea Benadives, Kriston Ramsey

EURēCA: Exhibition of Undergraduate Research and Creative Achievement

Emotion regulation (ER) is the experience and expression of emotions which aids in the balancing of positive emotions and emotional processing (Gross, 2001; Hölzel, 2011). An important advancement in the field of psychology is greater understanding of how treatments can positively influence ER. One promising intervention to improve emotion regulation is mindfulness training—the practice of being aware of one’s current internal state and thoughts to provide a greater attentiveness and acknowledgement to one’s current environment (Hoffman et. al., 2010; Langer 2000). The current study examined the effect of brief mindfulness training on emotion regulation after a sad mood induction via …

Testing A Model Based Approach To Selective And Flexible Attention, Anastasia Nicole Kerr-German

Masters Theses

A recent neural-process approach using dynamic field theory (DFT), put forth by Buss and Spencer (2014), demonstrated how a simple dimensional attention mechanism can explain the behavioral and neural data associated with the development of flexible attention and performance in the Dimensional Change Card Sorting task (DCCS). Taking a dynamical systems approach to the development of attention in executive functioning is critical as it allows us to further probe the underlying processes and mechanisms that give rise to later life success.

The goal of the current proposal is to generalize DFT in order to explain the development of selective attention …

The On-Screen Water Cooler: Effects Of Televised User-Generated Comments On Cognitive Processing, Social Presence, And Viewing Experience., Jaclyn Ann Cameron

Doctoral Dissertations

Social television combines traditional television viewing and interactions with social media to create a phenomenon that connects otherwise autonomous viewers through a shared viewing experience. This dissertation explores one type of social television: on-screen user-generated comments. Although the practice spans multiple television genres, little is known about its effect on viewers’ cognitive processing of the media, perceptions of the social presence of other viewers, or the viewers’ experience of the media. Two experimental studies explored the effects of on-screen user-generated comments on cognitive processing of the media message, the effect of manipulating the content of on-screen user-generated comments and individual …

Influences On Self-Regulated Learning In Low-Income Children: Examining The Role Of Private And Social Speech As Self-Regulation Tools, Lisa Ann Connor

Doctoral Dissertations

Self-regulated learning (SRL) allows children to become autonomous learners through facilitating their active planning, monitoring, and evaluation of their performance in the classroom. Low-income children have been found to exhibit lower SRL abilities compared to middle-class children. SRL is linked to a number of long-term academic outcomes, and thus, understanding what contributes to this ability is essential for intervention. One potential mediator of children’s emerging SRL abilities is language. Social Constructivist Theory provides a lens to view this relationship between language and SRL, denoting the importance of both the physical and social dimensions of the classroom when examining cognitive development. …

The Relationship Between Demands And Resources And Teacher Burnout: A Fifteen-Year Meta-Analysis, Tammy Marie Stewart

Doctoral Dissertations

This meta-analysis explored the phenomenon of teacher burnout— the biggest contributor to teacher attrition (Owens, 2013; Unterbrink, 2014; Yu, 2015). The focus of this study was to use meta-analytical procedures to explore the relationship between burnout dimensions (i.e., emotional exhaustion, depersonalization, and feelings of personal accomplishment) and specific demand and resource correlates. Demand correlates included work overload, role conflict, role ambiguity, and student misbehavior. Resource correlates included peer support, supervisory support, and decision-making. This meta-analytical research method encompassed fifteen years of published and unpublished studies from January 2000 through January 2015. A total of 116 studies met the following inclusion …

Central Executive Functioning And Electrodermal Levels In Adults With And Without Clinically Significant Attention-Deficit/Hyperactivity Symptoms, Megan Carl

Masters Theses

Adults diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD) demonstrate impaired performance on central executive (CE) functioning tasks (Alderson, Hudec, Patros, & Kasper, 2013a; Boonstra, Oosterlaan, Sergeant, & Buitelaar, 2005; Nigg et al., 2005) and underarousal of the sympathetic nervous system as measured by the electrodermal levels (EDLs) during resting state paradigms (Hermens et al., 2004). CE functioning and arousal are linked in three theoretical models of ADHD. No study to date has examined the degree to which EDLs (arousal) are related to ADHD-related cognitive impairments. This study examined (1) performance associated with central executive functioning and (2) EDLs while increasing CE processing …

The Association Of Gender, Rumination, And Depression On The Wais-Iv Working Memory Index, Audrey Ashton File

Masters Theses

Due to the prevalence of depression in college students and associated functional and cognitive impairment, a developing body of research is exploring factors that may negatively impact cognitive efficiency. Recent research has highlighted rumination as one variable that may reduce cognitive efficiency and exacerbate depression. This study examined the impact of rumination and gender on working memory in depressed (n = 29) and non-depressed undergraduates, (n =68) by examining performance on the Working Memory Index (WMI) of the WAIS-IV. Prior to WMI subtests, participants were randomly assigned to a rumination or distraction condition. After controlling for pre-experimental rumination, …

"The Natural History Of Truth: The Neurobiology Of Belief", Neil Greenberg

Faculty Publications and Other Works -- Ecology and Evolutionary Biology

The pursuit of truth is woven into the fabric of every organism*. Any estimate of how best to survive and thrive in the reality in which we are immersed requires a sense of self, of the world, and of their relationship to each other. I wish to explore the idea that this pursuit has at its heart two complementary modes of reality testing utilizing separate cerebral systems which deal, respectively with the correspondence of experience with the world and the coherence of the experience with previous experiences: “is it real” and “does it fit?” At multiple levels of the nervous …

The Psychology Of Memory, James Ernest Jackson

Masters Theses

Throughout all the ages man has had some faint realization of the tremendous importance of memory. Even today we realize its full importance only faintly. Memory is undoubtedly one of the most important functions of the mind. Without memory the mind is nothing. Memory is one of the basic and fundamental elements of the mind.
