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 …

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 …

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 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 …

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 …

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 …

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 …

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 …

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 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 …

The Effect Of A Mindfulness-Based Intervention On Attention And Cognitive Control As A Function Of Smartphone Notifications., Joshua D. Upshaw

Graduate Theses and Dissertations

Barriers to accessing mobile technology, particularly smartphones, have decreased substantially since the iPhone’s release in 2007, resulting in increased ownership and usage across all ages, genders, and races. Despite their ubiquity in our society, relatively little empirical work has investigated the influence of smartphones on our higher order executive functioning. Prior work has linked smartphone use with impaired cognitive control during cognitively demanding tasks, especially in heavier smartphone users. The goals of the current study were twofold. First, the study aimed to examine the effects of smartphone notifications on cognitive control and attention. And second, to determine the effects of …

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 …

Examining The Transient Neural Dynamics Underlying Working Memory Maintenance For Complex Visual Stimuli, Chelsea Reichert Plaska

Dissertations, Theses, and Capstone Projects

Working memory (WM) is the temporary storage of information to accomplish a future goal. The WM delay period is the time after encoding but before retrieval when information is being maintained, typically in the absence of relevant stimuli. Understanding how the brain supports maintenance during the delay period, and how neural activity and connectivity are related to memory is critical for advancing both basic knowledge as well as informing declines in memory and cognition related to neurodegenerative diseases and healthy aging. An open question in the field of WM research is how information is stored during this delay period. One …

Mental Imagery In The Regulation Of Differential Fear Conditioning: A Multimodal Investigation Involving Self-Report, Psychophysiology, And Brain Imaging, Tyler Daniel Robinson

LSU Doctoral Dissertations

Mental imagery is a common component in a range of emotion regulation techniques. However, the effectiveness and neural mechanisms of regulation via mental imagery are underexplored due to a lack of studies targeting mental imagery specifically. This discrepancy results in uncertainty regarding the mechanism of regulation in existing paradigms. Biased competition for attentional resources presents a plausible model by which a mental imagery-based distracter can downregulate response to an emotional stimulus. If visualizing an imagined distracter effectively regulates emotional response, the inclusion of mental imagery components in other techniques represents a potential confound. To address this discrepancy, this dissertation investigates …

The Effects Of Interactivity On Memory Relating To Presence In Virtual Environments, Jenny Wong

Psychological Science Undergraduate Honors Theses

The overall effectiveness of virtual environments is often linked to and measured by degrees of presence, commonly defined as the psychological sensation of “being there” (Schubert et al., 1999). Psychologists agree that attention and involvement through interactivity play a role in presence (Hartmann et al., 2015; Schubert et al., 1999; Witmer and Singer, 1998). Because attention is critical in encoding information into memory storage, looking at how memory relates to presence is another topic of interest. In this study, participants (N = 30) played through a 3D virtual reconstruction of a Pompeian house under one of two conditions: free-roam …

Mental Fatigue: Examining Cognitive Performance And Driving Behavior In Young Adults, Abigail F. Helm

Doctoral Dissertations

Mental fatigue causes an increase in task-based EEG theta and alpha power and a decrease in performance (for a review, see Tran et al., 2020). However, little is known about the emergence of mental fatigue in resting state EEG recordings and whether the progression of mental fatigue over time is influenced by individual differences. The current dissertation examined the utility of resting state EEG as a measure of mental fatigue by testing whether EEG power changed in young adults over the course of a cognitively demanding battery of tasks. The current dissertation also tested how this measure of mental fatigue …

Learned But Not Distracting: Low-Value Stimuli And Value-Driven Attentional Capture, John Albanese

Senior Theses and Projects

Stimuli previously associated with reward slow response times (RTs) when presented as irrelevant distractors in subsequent, unrewarded tasks (value driven attentional capture, VDAC). Typical VDAC training requires search for one of two experimentally-determined, colored circles and an orientation judgement of a line inside the color-defined target. Reward follows correct responses, associating high- or low-value with specific colors. Distractors rendered in high-value colors consistently slow RTs in an unrewarded test phase, an outcome that is rarely observed for low-value colors. Might this be due to a failure to adequately learn the reward contingencies during training? 22 observers underwent a modified training …

Effect Of Short-Storage Hrgcs On Driver Decision Behavior And Safety Concerns: Real-World Analysis And Experimental Evidence, Anne Linja

Dissertations, Master's Theses and Master's Reports

Vehicle-train collisions at highway-rail grade crossings (HRGCs) continue to be a safety concern, and despite improvements in warnings, many of these incidents are attributed to human error. In some cases, distractions other than railroad traffic, such as HRGCs with limited space between the railroad tracks and the highway intersection, may create additional cognitive burdens for drivers. We investigated the effect of HRGC type (short-storage vs. non-short storage) on driver attention and decision-making in two studies. In Study 1, we systematically analyzed 996 incidents from 2017-2019 from the Federal Railroad Administration’s Safety database. Driver decision making and outcomes were different depending …

Effects Of Spatial Language Cues On Attention And The Perception Of Ambiguous Images, Aaron Foster

Cal Poly Humboldt theses and projects

It’s a bird! It’s a plane! It’s superman!? Sometimes there are things in our world that are ambiguous. An ambiguous object, for the purposes of this thesis is any object that has more than one interpretation to it. The brain is designed to “fill in the blanks” and make sense of the world. Thus it will use anything available, like language, to help in resolving the ambiguity. Language can change how we perceive information in the world (Dils & Boroditsky, 2010) and where we direct our attention (Ostarek & Vigliocco, 2017; Estes et. al. 2008; Estes, Verges, Adelman, 2015). Language …

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 …

Attention Capture By Episodic Long-Term Memories: Evidence From Eye Movement Data, Allison Eleanor Nickel

Theses and Dissertations

Successfully navigating the world on a moment-to-moment basis requires the interaction of multiple cognitive processes. Therefore, studies that examine when and how these fundamental processes interact can provide important insights into how we behave. Many studies indicate that long-term memory can facilitate search for a target object (e.g., contextual cueing), however, the ways in which long-term memory might capture attention and disrupt goal-directed behavior have not been well studied. In five experiments, questions about whether encoded objects might capture attention, even when they are task-irrelevant, were addressed. Each experiment began with an encoding phase, where participants were instructed to commit …

The Effects Of Interruption Relevance And Complexity On Primary Task Resumption And Mental Demand, Brandon Allan Fluegel

Psychology Theses & Dissertations

In the present study, undergraduate students viewed patient charts and entered numerical values from these charts into a medical record database. They were unexpectedly interrupted by secondary tasks that differed in relevance and complexity. The secondary tasks varied by whether they facilitated or inhibited (i.e., relevant or irrelevant) rehearsal of the suspended task and whether they placed a demand on working memory (i.e., high complexity or low complexity). The primary measures of interest were the duration of time needed to resume the primary task and perceived mental demand. The Memory for Goals model (Altmann & Trafton, 2002) predicts that task …

The Process Of Therapeutic Change In The Attention Training Technique, Benjamin J. Laman-Maharg

Graduate Research Theses & Dissertations

Background: An unacceptably large proportion of individuals remain symptomatic after receiving first-line interventions. The attention training technique (ATT) is a potentially effective treatment augmentation and standalone treatment that may help improve the treatment of psychological disorders. The machanisms of therapuetic change of ATT remain understudied. This study is a randomized controlled trial of ATT compared to progressive muscle relaxation (PMR) that examined mindfulness and attentional control as potential mechisms of therapeutic change.

Method: A convenience sample of 64 participants (Mage = 20.13, SD = 3.65; 42.2% Male; 64.1% non-Hispanic White; 23.4% Black; 9.4% Hispanic/Latino; 3.1% Other) were randomly assigned to …

The Differences In Visuospatial Attentional Distribution Between Synesthetes And Non-Synesthetes, Identified Through Covert Visual Search, Kirsten Helena Ostbirk

Senior Projects Fall 2020

Synesthesia is a condition whereby sensory stimuli evoke unusual additional sensory perceptions and experiences, and can be identified through a visual search task. Grapheme-colour synesthetes have shown increased efficiency in visual search tasks, which some have hypothesized is a result of synesthetic colours drawing attention to the target stimulus, and have likened it to a weakened “pop-out” effect. Visual search has also been used to measure visuospatial attentional distribution, and findings from this method have supported the gradient model of attention, which proposes that cognitive resources are the most concentrated centrally in our visual field, and taper off, such that …

Do Distractor Suppression And Learning Intentionality Contribute To The Attentional Boost Effect?, Stephanie C. Crocco

Legacy Theses & Dissertations (2009 - 2024)

In the Attentional Boost Effect (ABE), a target-detection response enhances memory for simultaneously presented unrelated stimuli (Swallow & Jiang, 2010; see Swallow & Jiang, 2013 for a review). In two experiments, participants read aloud words simultaneously presented with a dot. Trials were presented every 1150 ms (Experiment 1) or every 2200 ms (Experiment 2). In a divided attention (DA) task, participants made a key-press to dots of a specific color. In a full attention (FA) task, they only read the words aloud while ignoring all dots. Under either intentional or incidental learning instructions, the DA task included Target words, and …

Components Of Mindfulness Training: Impacts On Attention And Affect, Maximilian Fey

Graduate Theses and Dissertations

The literature on mindfulness supports a distinction between two components of non-judgmental acceptance and directed attention. The present research analyzed whether there are distinct differences in attentional capabilities or affect between mindfulness inductions which differed in either including only directed attention or directed attention and non-judgmental acceptance. I hypothesized that the acceptance component of mindfulness would increase participants sustained attentional capabilities relative to a control condition; furthermore, I hypothesized that the non-judgmental acceptance component of mindfulness would lead to significant increases in positive affect and decreases in negative affect relative to control. Lastly, I hypothesized that an individual difference measure …
