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 …

Memory-Guided Selective Attention: An Instance Theory Of Automatic Attentional Control, Nicholaus Paul Brosowsky

Dissertations, Theses, and Capstone Projects

Cognitive control enables flexible goal-directed behavior via attention and action selection processes that prioritize goal-relevant over irrelevant information. These processes allow us to behave flexibly in the face of contradicting or ambiguous information and update behavior in response to the changing environment. Furthermore, they are thought to be in direct opposition to learned, automatic processing in that they enable us to disregard learned behaviors when they are inconsistent with our current goals. The strict dichotomy between stimulus-driven and goal-driven influences, however, has downplayed the role of memory in guiding attention. The position forwarded in this thesis is that a memory-based …

Visual Entrainment Of Perception-Related Neural Oscillations As A Mechanism For Maintaining Rhythmic Temporal Expectations Across A Wide Range Of Frequencies, Michael James Gray

Dissertations, Theses, and Capstone Projects

Visual sensitivity fluctuates rhythmically, in-synch with ongoing, EEG-recorded neural oscillations across a wide range of frequencies (~1-25hz). Some recent work has suggested that these perception-related neural oscillations can be entrained by rhythmic visual stimulation. Evidence is also emerging that the entrainment of ongoing oscillations in visual and auditory cortices is involved in rhythmic temporal expectations. In the introduction chapter, I attempt to bridge these bodies of literature and hypothesize that rhythmic visual stimuli automatically entrain ongoing, perception-related neural oscillations and that this mechanism supports the maintenance of rhythmic temporal expectations. Chapters 2 and 3 address this hypothesis from different angles. …

The Interaction Of Attention And Memory On The Reorienting Negativity, John C. Moses

Dissertations, Theses, and Capstone Projects

The three-stage model of distraction asserts that when we are presented with salient but task-irrelevant information, our sensory systems first detect the distracting stimulus by way of sensory memory buffers, which is indicated electrophysiologically by the mismatch negativity (MMN). Following detection, attentional resources are involuntarily allocated towards the processing of the distraction, as represented by the P3a. Finally, attentional resources are shifted away from the distracting stimulus and returned to the task-relevant information, as indicated by the reorienting negativity (RON). A great deal of research has focused on this last step in the model, largely centering around defining the mechanisms …

Using Meditation To Improve Measures Of Attention In Older Adults, Sabrina Ford

Electronic Thesis and Dissertation Repository

Age-related cognitive decline greatly impacts quality of life for older adults. Previous research has indicated that meditation may act as a neuroprotective factor to prevent age-related cognitive decline. This thesis sought to replicate previous findings and investigate if a four-week meditation intervention would improve sustained attention. Participants 60 years and older (n=27, 17 female) were recruited and assigned to a focused-attention (FA) meditation or relaxation group which met for four weeks, three times a week. Resting-state EEG was used to collect individual alpha peak frequency (iAPF) and frontal alpha asymmetry (FAA). The Sustained Attention to Response Task (SART) was also …

Behavioral Hypervigilance In A Normative Population, Karly Weinreb

Theses and Dissertations

Hypervigilance is conceptualized as a symptom of trauma-related disorders, however it can also occur in a normative population. To distinguish normative hypervigilance from trauma-related hypervigilance, 372 participants (123 trauma-exposed and 249 non-trauma-exposed) completed a questionnaire assessing hypervigilance in contexts. Trauma-exposed participants reported greater levels of hypervigilance in 3 contexts.

Functional Opponency In Working Memory Capacity Predicts Cognitive Flexibility In Problem Solving., Charles A. Van Stockum Jr.

Electronic Theses and Dissertations

Cognitive flexibility is a hallmark of individuals with higher working memory capacity (WMC). Yet, research demonstrates that higher WMC individuals are sometimes more likely to adopt rigid problem-solving approaches. The present research examines a novel account for these contradictory findings—that different WMC mechanisms interact in ways that both support and constrain cognitive flexibility. Across three studies, participants completed the water jug task—a problem-solving task requiring them to first establish and then break mental set using a complex strategy. Participants then completed measures targeting three WMC mechanisms: attention control, primary memory, and secondary memory. Study 1 demonstrated that primary memory and …

Attention As A Mechanism For Object-Object Binding In Complex Scenes, Kacie Mennie

LSU Doctoral Dissertations

The current study attempted to determine whether direct binding between objects in complex scenes occurs as a function of directed attention at encoding. In Experiment 1, participants viewed objects in one of these different types contexts: unique scenes, similar scenes, or arrays with no contextual information. Critically, only half of the objects were attended for each encoding trial. Participants then completed an associative recognition task on pairs of items created from the previously studied scenes. Test pairs consisted of two attended or unattended objects, and were associated with a unique scene, a similar scene, or an array. Evidence of binding …

Mapping Reward Values To Cues, Locations, And Objects: The Influence Of Reward Associations On Visual Attention, Constanza De Dios

USF Tampa Graduate Theses and Dissertations

Previous work has attempted to fit reward-driven attentional selection as being exogenous (stimulus-driven) or endogenous (goal-driven). However, recent work suggests that reward’s effects on attention depend on the type of stimulus feature that the motivational information is imparted during learning (incentive salience). If true, then reward should not be limited to solely impacting early perceptual or late categorization processes attention. The current study used event-related potentials (ERPs) to test the idea that reward’s effects on attention depend on the process that the reward information is embedded – early perceptual or late categorization. Results demonstrated reward-driven effects on perceptual representation when …

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

MSU Graduate Theses

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 …

Coupled Correlates Of Attention And Consciousness, Ravi Varkki Chacko

McKelvey School of Engineering 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 …

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, …

Levels-Of-Processing Effects On "Remember" Responses In Recognition For Familiar And Unfamiliar Tunes, Esra Mungan, Zehra F. Peynircioğlu, Andrea R. Halpern

Andrea Halpern

We investigated the effect of level-of-processing manipulations on "remember" and "know" responses in episodic melody recognition (Experiments 1 and 2) and how this effect is modulated by item familiarity (Experiment 2). In Experiment 1, participants performed 2 conceptual and 2 perceptual orienting tasks while listening to familiar melodies: judging the mood, continuing the tune, tracing the pitch contour, and counting long notes. The conceptual mood task led to higher d' rates for "remember" but not "know" responses. In Experiment 2, participants either judged the mood or counted long notes of tunes with high and low familiarity. A level-of-processing effect emerged …

Speech Interfaces And Pilot Performance: A Meta-Analysis, Kenneth A. Ward

International Journal of Aviation, Aeronautics, and Aerospace

As the aviation industry modernizes, new technology and interfaces must support growing aircraft complexity without increasing pilot workload. Natural language processing presents just such a simple and intuitive interface, yet the performance implications for use by pilots remain unknown. A meta-analysis was conducted to understand performance effects of using speech and voice interfaces in a series of pilot task analogs. The inclusion criteria selected studies that involved participants performing a demanding primary task, such as driving, while interacting with a vehicle system to enter numbers, dial radios, or enter a navigation destination. Compared to manual system interfaces, voice interfaces reduced …

Storytelling Study, Samantha Irene Pepe

Honors Theses and Capstones

Expressive prosody (i.e., a manner of communication that is characterized by lively rhythm and tempo) and inexpressive prosody (i.e., monotone speech) present different environments for listening to a story during a read-aloud session. This study aims to assess whether there are visual attention differences for preschoolers in these varied prosodic environments and how this affects comprehension.

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

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) …

Hearing And Seeing A Speaker: How Perceptual And Cognitive Factors Modulate The Dynamics Of Audiovisual Speech Perception, Elina Kaplan

Doctoral Dissertations

In face-to-face conversations, listeners process and combine speech information obtained from hearing and seeing the speaker talk. Audiovisual speech typically leads to more robust recognition of speech, as it provides more information for recognition but also as it helps listeners adjust to speaker idiosyncrasies. The goal of the current thesis was to examine how certain perceptual and cognitive factors modulate how listeners use visual speech to facilitate momentary speech perception and to adjust to a speaker’s idiosyncrasies. Results showed that (older) listeners’ sensitivity to cross-modal synchrony is related to the size of the audiovisual interactions during early perceptual processing. Furthermore, …

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

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

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

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 …

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 …

Investigating The Effects Of Sensory Learning In Rats Using Intra And Extra Stimulus Modalities, Ariel M. Kershner

Faculty Curated Undergraduate Works

The purpose of this study was to see what rats learn about the elements of a compound stimulus (a stimulus composed of two different stimuli), and whether their learning differs if the compound is from the same modality (intra-modal), i.e. both visual, or from different modalities (inter-modal), i.e. visual and auditory. We hypothesized that the rats would respond more to the compound stimuli than to the single stimuli (Pearce and Wilson, 1990), more to the compound modality of inter-modal elements than to the compound modality of intra-modal elements (Miller, 1971 and Gingras, 2009), equally to the intra-modal elements (Rescorla, 1972), …

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 …
