The Roles Of Biophilic Attitudes And Auditory Stimuli Within Attention Restoration Theory, Jason B. Boggs
The Roles Of Biophilic Attitudes And Auditory Stimuli Within Attention Restoration Theory, Jason B. Boggs
UNLV Theses, Dissertations, Professional Papers, and Capstones
Attention Restoration Theory indicates that interacting with nature allows one’s fatigued, directed attention to be restored. This effect has been documented and produced through directed interaction with nature, such as a walk in the park, as well as through indirect interactions (e.g., photographs). The current dissertation was designed to: 1) investigate whether and how biophilic attitudes affect the attention-restoring effects incurred from interactions with nature, and 2) extend the research on ART by assessing the impact of nature-related audio stimuli. A total of 184 participants completed an assessment of biophilic attitudes, engaged in attention fatiguing exercises, and participated in one …
The Consequences Of Processing Of Goal-Irrelevant Information During The Stroop Task In Younger And Older Adults, Jessica Nicosia
The Consequences Of Processing Of Goal-Irrelevant Information During The Stroop Task In Younger And Older Adults, Jessica Nicosia
Arts & Sciences Electronic Theses and Dissertations
Recent evidence from memory paradigms indicates that older adults can sometimes benefit more from processing goal-irrelevant information than younger adults, however these studies have often failed to simultaneously provide evidence of age-related control deficits. In the present experiments, participants initially studied a list of words. They then received a color-naming Stroop task where neutral words were either previously studied or new words. Across three experiments, participants were given different types of memory tests to examine the lingering effects of the neutral words during color-naming in younger and older adults. The results from all three experiments (including an attempted replication study) …
Rumination And Rebound From Failure: Investigating How Trait And State Forms Of Ruminative Thought Influence Attention To Errors And The Ability To Correct Them In A Challenging Academic Environment, Ronald C. Whiteman
Dissertations, Theses, and Capstone Projects
Rumination is a recurrent and repetitive manner of thinking that can be triggered by blockage of personally-relevant goals, creating a temporary state of abstract and evaluative self-focus that can also become a chronic trait-like style of responding to personal challenges. Despite claims that rumination helps down-regulate unwanted emotion, cope with problems, and lead to goal attainment, it often increases negative affect, interferes with problem solving, and exacerbates goal-state discrepancies, particularly for women. Given the pervasiveness of rumination and its potential impact on cognitive processes and emotional states, one important yet untested question is how it might impact individuals’ ability to …
Long-Term Focus Of Attentional Biases, Garrett Pollert
Long-Term Focus Of Attentional Biases, Garrett Pollert
Graduate Theses and Dissertations
Prior research regarding attentional biases, or patterns of visual attention, have focused on attention over the initial second when exposed to pictoral food stimuli. This manuscript reviews the literature regarding attentional biases in overweight/obese individuals over this timeframe for the two previously defined components of attentional bias (attentional orientation and attentional maintenance). A new component is proposed, called “attentional re-engagement,” defined as the pattern of attentional shifts towards target stimulus types over longer periods of time. Overweight/Obese and Normal-weighted participants were recruited and engaged in an Extended Dot Probe task, wherein attentional orientation, maintenance, and re-engagement were assessed using the …
Examining The Influence Of Executive Resources And Mathematical Abilities On Framing Biases, Gabriel Allred
Examining The Influence Of Executive Resources And Mathematical Abilities On Framing Biases, Gabriel Allred
UNLV Theses, Dissertations, Professional Papers, and Capstones
The finding that the presentation of a choice (i.e., either as a loss or a gain) can affect and bias our willingness to engage in risk is one of the paramount findings of behavioral economics. First discussed by Tversky and Kahneman (1981), the framing effect demonstrates that when given two choices framed as a loss, we tend to become risk seeking. However, when the exact same outcome is presented as a gain, we become risk averse, choosing the more conservative option, regardless of the actual expected value. The effect is not limited to general research samples but has been demonstrated …
Change Deafness: A Comprehensive Examinations, Vanessa Claire Irsik
Change Deafness: A Comprehensive Examinations, Vanessa Claire Irsik
UNLV Theses, Dissertations, Professional Papers, and Capstones
Environmental changes are a vital source of information which can drive advantageous behavioral responses. For example, detecting visual changes can be critical when driving a vehicle or when simply walking down a busy street. Auditory perception is an essential complement to vision as it can allow awareness of changes in and out of sight. While subjective perception would suggest that our sensory representation of the world is complete, research on change deafness indicates that quite often the opposite is true. Healthy listeners often miss salient, suprathreshold auditory changes. Three separate manuscripts will be presented, each of which aims to advance …
A Comparison Of Function- And Nonfunction-Based Extinction For Inappropriate Mealtime Behavior, Caitlin Kirkwood
A Comparison Of Function- And Nonfunction-Based Extinction For Inappropriate Mealtime Behavior, Caitlin Kirkwood
Theses & Dissertations
Previous literature supports the use of a functional analysis to prescribe treatment for children with feeding disorders (Bachmeyer et al., 2009; Piazza, Fisher, et al., 2003). Nevertheless, clinicians often train caregivers to use healthy contingencies, independent of whether those contingencies are function based. We do not know, however, whether including nonfunction-based contingencies differentially affects inappropriate mealtime behavior. In the current study, we observed that caregivers of 3 children with feeding disorders provided escape from bites and drinks and attention following inappropriate mealtime behavior. Results of a functional analysis showed escape from bites or drinks, but not attention, reinforced inappropriate mealtime …
Electrophysiological Biomarkers Of Chemotherapy-Related Cognitive Impairment In Hematological Malignancy Patients, David E. Anderson
Electrophysiological Biomarkers Of Chemotherapy-Related Cognitive Impairment In Hematological Malignancy Patients, David E. Anderson
Theses & Dissertations
Multiple cancer populations frequently report cognitive impairment following treatment with chemotherapy agents (“chemo-brain”). Impaired neuropsychological performance is commonly reported in cognitive domains of attention and executive function. Understanding neural mechanisms underlying cognitive impairments is essential to developing prevention and rehabilitation strategies. Brain imaging studies frequently show chemotherapy-related impairments within the attentional control network, which is comprised of a constellation of cortical regions that govern reportedly impaired cognitive functions. In the current dissertation research, I developed a novel electrophysiology battery aimed at recording near-instantaneous neural activity within the attentional control network during cognitive task performance. Cancer patients diagnosed with hematological malignancy …
The Effects Anxiety Has On Attentional Bias And Working Memory, Breana Mcswain
The Effects Anxiety Has On Attentional Bias And Working Memory, Breana Mcswain
USC Aiken Psychology Theses
Research has shown that anxiety impairs attention and working memory, especially when it comes to completing a mentally demanding cognitive task such as the emotional Stroop paradigm or the n-back task. The purpose of this study was to investigate whether state anxiety affects behavioral performance on executive function tasks. State anxiety was induced using negatively valenced images from the International Affective Picture System, while neutral images served as the control. We compared behavioral performance between individuals in the negative mood induction against those in the neutral mood induction. Trait anxiety was used as a covariate for both groups. This allowed …
Childhood Lead Exposure And Attention-Deficit/Hyperactivity Disorder Symptoms: A Meta-Analysis, Megan Glenn Brown
Childhood Lead Exposure And Attention-Deficit/Hyperactivity Disorder Symptoms: A Meta-Analysis, Megan Glenn Brown
Walden Dissertations and Doctoral Studies
Lead exposure during childhood is a significant global public health concern as the potential effects of exposure can result in the need for long-term treatment, diminished productivity in society, and financial strain on the health care system. There is strong evidence of a relationship between lead exposure and attention-deficit/hyperactivity disorder (ADHD); however, there is a gap in the current literature regarding the relationship between lead exposure and specific symptoms of ADHD and the strength of that relationship. The purpose of this meta-analysis was to examine and help quantify this relationship. Cohen's d was used as the standardized mean effect size …
Towards Improving Learning With Consumer-Grade, Closed-Loop, Electroencephalographic Neurofeedback, Zall Soren Hirschstein
Towards Improving Learning With Consumer-Grade, Closed-Loop, Electroencephalographic Neurofeedback, Zall Soren Hirschstein
Senior Projects Spring 2018
Learning is an enigmatic process composed of a multitude of cognitive systems that are functionally and neuroanatomically distinct. Nevertheless, two undeniable pillars which underpin learning are attention and memory; to learn, one must attend, and maintain a representation of, an event. Psychological and neuroscientific technologies that permit researchers to “mind-read” have revealed much about the dynamics of these distinct processes that contribute to learning. This investigation first outlines the cognitive pillars which support learning and the technologies that permit such an understanding. It then employs a novel task—the amSMART paradigm—with the goal of building a real-time, closed-loop, electroencephalographic (EEG) neurofeedback …
An Analysis Of The Ego-Depletion Effects Of Emotion Versus Attention Draining Tasks: Even Emotionally Arousing Depletion Tasks Do Not Show An Ego-Depletion Effect, Savannah Binion
Senior Independent Study Theses
The theory of ego-depletion has come under intense scrutiny within the past few years. Beginning around 2010, researchers conducted meta-analyses and large replication studies that have investigated this topic, and found a wide range of evidence for and against the existence of an ego-depletion effect. Although the goal has been to determine whether this effect exists or not, the research has proved that the answer may be more complicated than that. The purpose of the current research was to examine the different theories about self-control, and to test two specific depleting tasks against a control group. The depleting tasks were …
Visual Search In Naturalistic Imagery, Dave Schreifels
Visual Search In Naturalistic Imagery, Dave Schreifels
Dissertations, Master's Theses and Master's Reports
Visual search has been extensively studied in the laboratory, yielding broad insights into how we search through and attend to the world around us. In order to know if these insights are valid, however, this research must not be confined to the sanitized imagery typically found within the lab. Comparatively little research has been conducted on visual search within naturalistic settings, and this gap must therefore be bridged in order to further our understanding of visual search. Based on the results of Experiment 1, Experiment 2 was conducted to test three common effects observed in previous studies of visual search: …
The Influence Of Television Pacing On Attention And Executive Functioning, Timothy Lavigne
The Influence Of Television Pacing On Attention And Executive Functioning, Timothy Lavigne
Graduate College Dissertations and Theses
Television shows, especially cartoons, are one of the most common types of media in children’s lives. Although there is a well-established connection between television exposure and difficulties with attention, it is unclear if all types of television are equally impactful. Given the amount of time children are exposed to television, there is a need to better understand which components of shows may or may not impact one’s attentional and executive functioning abilities. One such factor is the pace of the content. The current study expands on this limited area of the literature by utilizing a 9-minute 30-second long cartoon video, …
