Target Selection And Enhancement During Attentional Tracking, Marvin R. Maechler

Dartmouth College Ph.D Dissertations

At any waking moment, we are bombarded with more sensory information than we can fully process. Attention is necessary to deal with the dynamic world we live in. One fundamental function of vision and attention is to keep track of moving objects, but what are the targets of attention during tracking?

One of the first theories of attentional tracking predicted that targets would be selected at early processing stages. By employing the double-drift illusion, which dissociates physical and perceived positions of moving objects, we investigated which of these positions is selected for tracking. Contrary to earlier theories and in line …

Attention Bias To Climate Change Images Following Emotional Inducements Of Pride And Guilt, Caleb W. Coughtry-Carpenter

All NMU Master's Theses

Climate change is the most important issue facing modern day humans, and the solutions are not developing at a quick enough rate. In many cases, human-derived climate effects have crossed the threshold to becoming irreversible, and, as we remain inactive, are continuing to worsen as mitigating steps are not taken. Some of the most devastating effects facing humans include rising sea levels that threaten to flood coastal regions, and heatwaves of heightened intensity which threaten access to potable water and loss of food crops. Humans are not the only victims of climate change. Ecosystems are also greatly threatened by climate …

Examining The Moderating Effects Of Noncognitive Factors On College Students With And Without Attentional Difficulties: A Pilot Study, Faye Domokos

Masters Theses

Individuals diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD) are less likely to pursue higher education and more likely to face numerous challenges, such as increased rates of academic probation, withdrawal from classes, lower GPAs, and decreased graduation rates (Advokat et al., 2011; Heiligenstein et al., 1999; Wolf, 2001). Based on Farrington’s conceptual model of noncognitive factors that predict academic performance (2012), this study utilized a hierarchical multiple regression framework to evaluate whether the strength of the relation between inattention symptom severity and academic functioning is moderated by academic motivation. Additionally, moderated moderation analyses were conducted to assess whether the moderating effect of …

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 …

Rethinking Attention Control: An Individual Differences Approach, Vincent A. Medina

LSU Doctoral Dissertations

While there is extensive literature on visual spatial attention, less is known about auditory spatial attention, especially in terms of attention control. There is also a growing literature highlighting the importance of considering individual differences in attention control ability. Given these points, the purpose of this study was twofold. The first was to understand how auditory attention control is influenced by spatial location as well as vision. The second was to examine whether individual differences in attention control ability can predict task performance in that context. We utilized two tasks for these purposes. Experiment 1a consisted of a cross-modal Stroop …

Assessing How Bilingual Experience Impacts Performance In Stimulus-Stimulus And Stimulus-Response Conflict Tasks, Christian Ruiz-Ortiz

Open Access Theses & Dissertations

Numerous studies have revealed that bilingual individuals outperform monolinguals in tasks requiring executive control. However, the exact impact of bilingualism on executive functions remains unclear due to inconsistent findings in the literature. These discrepancies may stem from factors such as participant demographics, variations in definitions and operationalizations of bilingualism, and task selection. To address these issues, we investigated the link between degree of balance and contextual use with the ability to address conflict across sensory modalities (auditory and visual) at different stages of processing. Rather than focusing on mean performance, this study investigated performance stability (coefficient of variation) over time …

Evaluating The Attention Training Technique As A Transdiagnostic Intervention For Fear-Based Psychopathological Symptoms: A Randomized Controlled Trial, Benjamin John Ellem

Graduate Research Theses & Dissertations

Recent research indicates that fear-related psychological disorders are a distinguished class of psychopathology, all of which share the underlying endophenotype of maladaptive acute fear responding. The relationship between maladaptive fear responding and psychopathology has been found to be moderated by executive functioning capacity—most notably attentional control. However, the current psychopathological nosology does not link fear-based disorders together. As a result, many fear-based disorders are treated separately with different evidence-based psychotherapies. These psychotherapies tend to focus on reducing phenotypic behaviors or self-reported experience of symptoms. Individuals with fear-based disorders may be better served by treatments that focus on the aforementioned endophenotypes …

Prenatal Ethanol Exposure Impairs Performance On Spatial And Tactile Sequential Discrimination Task In Juvenile Rats, Caleb S. Bailey

Theses and Dissertations--Psychology

Fetal alcohol spectrum disorders (FASDs) are a set of cognitive and behavioral abnormalities that arise in ~5% of children who have been prenatally-exposed to alcohol. Prenatal alcohol exposure (PAE) can cause impairments in learning acquisition, working memory, response inhibition, and attentional-set shifting that result in exaggerated deficits in executive function and impairments in goal-seeking behavior. There are standard procedures used in rodent research to address some components of these deficits, but few procedures are sensitive enough to comprehensively assess such deficits. To address this issue in FASDs research techniques, we developed a procedure that requires prolonged executive function in a …

The Structure Of Working Memory: A Review And New View Of Psychometric Models, Kevin Pablo Rosales

CGU Theses & Dissertations

Beginning in the 1970s, a great deal of research in cognitive psychology, developmental psychology, psychometrics, and cognitive neuroscience has investigated the structure and function of working memory (WM), defined as the ability to actively maintain and manipulate information in the service of complex cognition (Baddeley & Hitch, 1974). It is well established that WM is a limited capacity system and individual differences in WM capacity are strongly associated with important cognitive abilities and outcomes, such as general intelligence (Engle et al., 1999) and academic achievement (Swanson & Berninger, 1996; Ramirez et al., 2013). For this reason, WM is a central …

Attention, Working Memory, And Adaptive Functioning In Emerging Young Adults With Psychometrically-Defined Schizotypy, Parth Nakirikanti

Honors Undergraduate Theses

Schizotypy, a complex construct linked to schizophrenia-related traits, encompasses positive, negative, and disorganized symptoms. This study offers a review of the concept of schizotypy, including its historical evolution, tracing it from Bleuler's early mention in 1911 to Meehl's continuum model. Embracing a dimensional perspective, this research underscores the interplay of biological, psychological, and social factors in understanding schizotypy. Deficits in sustained attention and working memory within schizotypy remain underexplored, with prior studies yielding inconsistent results. Adaptive functioning deficits in individuals with schizotypy are also inadequately understood. Examining a college student population, this investigation utilized scores on the Schizotypal Personality Questionnaire …

Adhd Symptoms And Inattentional Blindness In An Undergraduate Sample, Katherine Rose Matchett

Electronic Theses and Dissertations

The relationship between Attention-Deficit/Hyperactivity Disorder (ADHD) and the phenomenon of inattentional blindness has received little empirical attention, with only a single published study on the topic. The purpose of the present study was to investigate individual differences in ADHD symptom severity in a non-clinical, undergraduate sample as they relate to susceptibility to inattentional blindness. Because research conducted in an individual differences framework requires the use of reliable measurement instruments, the present study also set out to develop and pilot a task that could induce inattentional blindness repeatedly and reliably in the same participants. The results showed that a) the measure …

Differences In Attentional Processing Of Sexual Stimuli For Men With Varying Degrees Of Sexual Arousal Function, Robert Brandon Wyatt

Graduate College Dissertations and Theses

Sexual arousal problems remain prevalent for many men despite the availability of medications such as phosphodiesterase type 5 (PED5) inhibitors used to treat sexual dysfunction. Theoretical models that attempt to explain the underlying psychological mechanisms of sexual dysfunction highlight the important role of attention during sexual arousal (e.g., Barlow, 1986; Janssen, Everaerd, Spiering, & Janssen, 2000), but fail to integrate a contemporary understanding of attentional processes (i.e., preattentive and selective; Broadbent, 1958, Driver, 2007; Triesman, 1969) to explain why individuals with and without sexual arousal problems direct their attention toward or away from a given stimuli during sex. Moreover, these …

The Long-Term Effects Of Cannabis On Attention To Motion, Rachel Mccaig

Theses and Dissertations (Comprehensive)

The purpose of the following study was to investigate the long-term effects of cannabis use on attention to motion.

Methods: Cannabis users, who varied in age of onset of use, were compared to control participants after abstaining from cannabis for at least 24 hours. One-hundred and ninety-seven participants engaged in a cognitive assessment followed by a motion discrimination task and an attention to motion task. The assessment consisted of a series of standard tasks that measured a range of cognitive processes such as attention, memory, and executive functioning. The motion discrimination task assessed the participants’ abilities in discriminating between various …

A Novel Test Of Emotion Recognition Bias Using Dynamic Facial Morphing, Michael R. Gallagher

Theses and Dissertations

Depressed persons have demonstrated emotion based cognitive biases, specifically surrounding vigilance of negative information and avoidance of positivity. These biases are sometimes operationalized through emotion recognition tasks. However, previous emotion recognition tasks lack in their ability to accurately measure and decompose positivity avoidance with enhanced negativity, while accounting for basic cognitive processes that can drive the results. Therefore, we developed a novel emotion recognition task that examines emotional intensity thresholds, while accounting for general response bias. Linear mixed effects modeling revealed substantial individual differences on all conditions in the task, using both frequentist and Bayesian approaches. Additionally, the findings suggest …

Effects Of Top-Down Attention And Individual Differences On Recognition Memory And Recollective Experience., Anna Kelley

Electronic Theses and Dissertations

Memory accuracy and detail hold practical importance, and psychology has studied means to improve memory. One such means is performing visually guided saccades immediately before a memory test. Previous work has found this intervention to improve memory performance, an effect dubbed Saccade-Induced Retrieval Enhancement or SIRE. The top-down attentional control account posits that SIRE occurs because saccades activate attentional control regions in the brain, which contributes to executing top-down attentional control when searching memory. The current experiment tested this account of SIRE by attempting to replicate previous results and investigating whether a different attentional task, the Revised Attention Network Test …

The Neurotic Wandering Mind And Self-Efficacy During Training, Mario L. Arredondo

Legacy Theses & Dissertations (2009 - 2024)

AbstractPersonality is complex and dynamic, and because this attribute consists of a cluster of different distinctive traits, successfully predicting how personality predisposes individuals to different reactions and feelings during a learning activity is an equally complex and challenging task. For this thesis I will focus on the personality trait of low emotional stability, or neuroticism. Previous research has shown that people with lower emotional stability have a predisposition to be more stringent with self-perceptions across different domains of behaviors and feelings. Self-efficacy influences people’s confidence in their ability to exert control over their own behavior and impact their environment, all …

So I Was, 'Like', Totally Buggin’ – Evidence For The Role Of Attention On Entrainment From Discourse Particles, Rachel L. Williams

Open Access Theses & Dissertations

In this study, we investigated the role of attention for entrainment during production and comprehension using the discourse particle like. We tested two main hypotheses – that entrainment to discourse particles, even if relatively implicit, requires some attentional resources, versus that it requires little (if any) attention. In two experiments, participants read a short story and retold it (baseline retelling phase), then read another short story and listened to a recording of it (priming phase), and then read and retold a third story (target retelling phase). In Experiment 1, half of the participants simultaneously navigated a busy pedestrian zone in …

Classical Conditioning Of Cognitive States, Arthur Burns

Neuroscience Honors Papers

Classical conditioning has been a fundamental concept and practice throughout the history of psychology. While classical conditioning traditionally seeks to elicit target behaviors in correlation to specific stimuli, we sought to do the same with cognitive states in place of behaviors. Specifically, we wanted to determine the effectiveness of conditioning states of cognitive arousal in human participants in conjunction with cues presented in a designed learning task. We designed a cognitive task specifically for this research, referred to as “the Tone Pitching Task”, which utilized a combination of working memory and mental processing in order to elicit cognitive arousal and …

Divided Attention And Its Effect On Forward Testing, Nicholas H. Garcia

UNF Graduate Theses and Dissertations

The testing effect is a well-studied and robust phenomenon. The forward testing effect is a relatively new phenomenon that has been observed in robust settings with a diverse population. The testing effect (also coined the backwards testing effect) and the forward testing effect share similar benefits and are applicable in similar settings. Research on the forward testing effect has demonstrated underlying mechanisms that differ from the backwards testing effect, illuminating the differences between these two phenomena. Dividing attention during study periods has been revealed to negatively affect the backwards testing effect, significantly reducing its efficacy. The forward testing effect, operating …

The Role Of Caregiver-Reported Emerging Social Attention In Predicting Duration Of Orienting And Social Communication, Casey E. Swick

Master's Theses and Doctoral Dissertations

Early identification of atypical development could lead to opportunities for earlier intervention, ultimately improving developmental outcomes. Early signs of atypical attention, social attention, and social communication development emerge in infancy, yet age at diagnosis of neurodevelopmental difficulties does not typically occur until well after the first year of life. In order to achieve this goal of early identification, sensitive and accessible tools are needed to identify infants at risk for atypical development. This study examined whether caregivers could report on emerging social attention behaviors in the first days to weeks of life with a novel, experimental scale (PediaTrac SSIP). This …

An Examination Of Working Memory, Spatial Awareness And Expertise In Athletes, Non-Athletes And Sports-Fans, Camilia Rios

Electronic Theses and Dissertations

Sport-specific practice of movement techniques is undoubtedly important in young athletes' sport performance. However, in sports that are more heavily reliant on open skills, cognitive factors, such as working memory (WM), attention, and spatial awareness, are more likely to become a barrier for proficiency than form or physical prowess. Nevertheless, the intricacies of the relationships that exist between these cognitive factors has gone relatively unexplored, particularly in the context of sport. The present research explored the impact of sport-specific experience on measures of WM, attentional control, and spatial awareness, and their interactions, through the lens of athletic expertise. Participants consisted …

The Effect Of School-Based Mindfulness Intervention On Student Attention And Executive Function: A Meta-Analysis, Sarah E. Rea

Electronic Theses and Dissertations

Schools are facing increasing responsibility to foster the social-emotional development of students. One way in which schools can improve student functioning is through school-based mindfulness interventions. Using mindfulness practices, in particular, can teach students to increase their attention of surroundings and internal experiences, and awareness of their thoughts and behaviors. While the evidence-base for mindfulness interventions in schools continues to grow, there are several studies that show promising outcomes. The purpose of this study was to determine how large the effect sizes for school-based mindfulness studies are in regard to increasing student attention, cognitive flexibility, and working memory. Results indicate …

The Role Of Emotional Attention Regulation In High Psychopathy Incarcerated Males, Michael K. Webb

Dissertations and Theses

This study examined the role of emotional attention regulation in men (N = 60) currently incarcerated in a Midwestern prison. Modern conceptualizations define psychopathy as a multifaceted and dimensional construct that includes atypical experience of affect, interpersonal problems, and remarkable social deviance. Attentional differences and deficient emotional experience have been shown to predict psychopathy and other outcomes related to the construct. However, attentional and emotional functioning in individuals high in psychopathy is complex and results have been shown to vary across discrete emotion states and experimental paradigms. The negative preception hypothesis (Kosson et al. 2018) suggests that these differences may …

An Erp Study Of The Effects Of Iconic And Nonsense Gestures On Memory Formation, Brianna E. Cairney

LSU Master's Theses

Co-speech gesture is an important part of human communication and aids in comprehension, learning, and memory. The addition of iconic gestures to speech has been shown in prior work to enhance memory for the speech. However, it remains unclear as to whether this benefit requires gestures to be meaningful, or, conversely, if any attentionally-engaging gesture will enhance memory. In the current study, we tested two theories to explain the mnemonic benefits of co-speech gesture: Dual Coding Theory, which attributes these benefits to multimodal encoding and enhanced imageability, and Attentional Highlighting Theory, which posits that gestures draw more attention to concurrent …

The Utility Of The Test Of Everyday Attention For Children (Tea-Ch) For Attention-Related Referrals, Ewelina Lakomy

Dissertations

The Test of Everyday Attention for Children (TEA-Ch) is a commonly used, UK-normed test to assess diverse attentional capacities in children and adolescents. Currently, there is insufficient evidence for the diagnostic utility of the TEA-Ch with ADHD in a U.S. population. The focus in this study was to investigate the relationship between the TEA-Ch scores test authors found to be most sensitive to ADHD in UK samples as well as the relationship of TEA-Ch scores to other measures typically used in the diagnosis of ADHD, including rating scales. Archival and prospective analyses of 121 subjects with mixed-clinical/ADHD diagnoses (ages 6–16; …

The Role Of Top-Down Attention In Statistical Learning Of Speech, Stacey Reyes

Electronic Thesis and Dissertation Repository

Statistical learning (SL) refers to the ability to extract regularities in the environment and has been well-documented to play a key role in speech segmentation and language acquisition. Whether SL is automatic or requires top-down attention is an unresolved question, with conflicting results in the literature. The current proposal tests whether SL can occur outside the focus of attention. Participants either focused towards, or diverted their attention away from an auditory speech stream made of repeating nonsense trisyllabic words. Divided-attention participants either performed a concurrent visual task or a language-related task during exposure to the nonsense speech stream, while control …

Binge-Watching And The Spacing Effect, Michael R. Austin

Masters Theses, 2020-current

Binge-watching, defined as consuming at least three episodes or three hours of video media in one sitting, is an increasingly prevalent behavior in the digital age. But scant research exists investigating how binge-watching affects memory for what was watched. Literature surrounding the spacing effect, defined as superior memory for information presented repeatedly across longer spans of time, would predict a memory deficit for binged material. However, findings from previous unpublished research by Fogler and colleagues do not align with this prediction. To investigate the dissonance, the aim of this research is to replicate and extend the work of Fogler and …

Mentally Restorative Areas For Students: Impacts Of Nature On Psychophysiological State, Jesse Moore

Honors Theses

Situated in the top outdoor ranking city of Chattanooga, the campus of the University of Tennessee at Chattanooga (UTC) includes diverse areas available for student rest and recreation. This study aims to introduce UTC students into the collection of studies on the effects of natural environments on Attention Restoration Theory (ART) by using the Stroop cognitive test and portable electroencephalograph (EEG) headsets. Participants completed the Stroop test after ten-minute mental restoration sessions in environments of varying natural exposure included on campus. Through analysis of variance, location was found to significantly influence performance on Stroop testing and measures of relaxation (p=0.030). …

The Influence Of Human Attentional State And Familiarity On Bengal Tiger (Panthera Tigris Tigris) And Siberian Tiger (Panthera Tigris Altaica) Sociability, Jenna J. Dail

MSU Graduate Theses

An essential element of an animal’s character is sociability (Gosling and John, 1999) and is demonstrated through interactions with other individuals (Capitanio, 2002). Although it is common to believe that domestic cats are not social beings, they have exhibited variance in solitary and social behavior, contingent on their environment and history (Turner, 2014). Much of the research on sociable behavior of animals has been completed between conspecifics. There has been less examination into interspecies sociability, and that which has been reviewed is focused on the relationship between humans and the domestic dog (Udell et al., 2010). Following this work, Vitale …

Cerebellum-Seeded Functional Connectivity Changes In Trait-Anxious Individuals Undergoing Attention Bias Modification Training, Katherine Elwell

All NMU Master's Theses

Anxiety and anxiety related disorders are increasing at a drastic rate in the past decade, with the NIMH reporting that 31.1% of U.S. adults will experience an anxiety disorder at some point in their lives. Anxiety is commonly characterized by increased attention bias to threat. Attention Bias Modification (ABM) is a new treatment used to reduce individual’s attention bias towards threat. The extent to which ABM leads to underlying neural changes is still unknown. The cerebellum is a neglected brain structure, with new research provides evidence that cerebellum’s functional connectivity and shared networks with threat processing regions has a direct …
