Grasping Type Affects Configural Encoding In Visual Working Memory, Shinhae Ahn Dec 2023

Grasping Type Affects Configural Encoding In Visual Working Memory, Shinhae Ahn

Arts & Sciences Electronic Theses and Dissertations

Previous research has shown that different grasping actions selectively influence the processing of simple visual features based on their relevance to the specific action. However, it remains uncertain if this interaction extends to abstract and higher-order information, such as global configuration extracted from an array of visual objects. The present study aimed to investigate the impact of different grasping types on the processing of configural shape information in visual working memory (VWM). In Experiment 1, participants engaged in a VWM change detection task while adopting either power- or precision-grasping postures. The availability of configural shape information was manipulated through the …


Exploring The Use Of Time Delay As A Pragmatic Cue In Text Messaging, Nicklas Phillips Dec 2023

Exploring The Use Of Time Delay As A Pragmatic Cue In Text Messaging, Nicklas Phillips

Masters Theses, 2020-current

Text messaging is often used as a stand-in for face to face communication. While texting mimics the rapid back and forth, turn taking nature of oral conversation, it lacks many of the pragmatic cues conversationalists ordinarily rely on to establish common ground and inform their understanding of sometimes nonliteral meaning conveyed to them. To get around this hurdle, texters have developed sets of textisms. These are specific cues that can be used to make up for the lack of pragmatic information in the texting environment. Examples include emoji, emoticons, and punctuation. This is an experimental study exploring whether time can …


Spontaneous Simulation Of Future And Past Events, Mackenzie Bain Dec 2023

Spontaneous Simulation Of Future And Past Events, Mackenzie Bain

Electronic Thesis and Dissertation Repository

Spontaneous future and past events come to mind unintentionally. Previous research supports that environmental cues prompt spontaneous simulation, although the role of specific cues remains unaddressed. Previous work has found that involuntary autobiographical memories are generated in chained-event sequences, which refers to multiple, related events being generated consecutively. We addressed how event and location cues influence spontaneous future and past events, and whether future events occur in chains. In a boring vigilance task, 132 participants located a left-facing arrow amongst right-facing arrows. On 49 of 350 trials, participants encountered event or location cues. Ten times, participants audio-recorded off-task thoughts they …


Mrs. Dalloway As A Window For Understanding Life, Kristen Venegas Dec 2023

Mrs. Dalloway As A Window For Understanding Life, Kristen Venegas

English (MA) Theses

Virginia Woolf’s Mrs. Dalloway may be dismissed as fiction, and fiction consequently is dismissed as fantasy. However, the novel enables readers to practice an intellectual exercise of meta-awareness that extends beyond the pages and onto real world phenomena. Under a cognitive neuroscience perspective, Mrs. Dalloway is a literary masterpiece due to its hyper- realistic execution of the intimacies of life. Through the narrative style of free-indirect discourse, Woolf illustrates what occurs in the minds of characters as they develop their own perceptions of reality and identity, exposes the fear and inadequacies of mankind’s distress in times of chaos and disorder …


Diminishing Creative Returns: Predicting Optimal Creative Performance Via Individual Differences In Executive Functioning, Kent F. Hubert Dec 2023

Diminishing Creative Returns: Predicting Optimal Creative Performance Via Individual Differences In Executive Functioning, Kent F. Hubert

Graduate Theses and Dissertations

A robust finding in creativity research is that during idea generation, later (vs. earlier) responses on a divergent thinking task tend to be more creative, while the number of responses start off quickly, and then slow down over time, termed the serial order effect. Divergent thinking and time may follow a diminishing returns curve, where there is an optimal amount of time that should be spent while generating ideas. Executive functions (inhibition, updating, and shifting) have been associated with divergent thinking, specifically with the idea generation phase, but the effect of individual differences on the temporal dynamics of divergent thinking …


Examining Task-Related Differences In The Error-Related Negativity (Ern) As A Function Of Cognitive Control Strategy And Trait Anxiety, Russell Mach Dec 2023

Examining Task-Related Differences In The Error-Related Negativity (Ern) As A Function Of Cognitive Control Strategy And Trait Anxiety, Russell Mach

Graduate Theses and Dissertations

Anxiety disorders pose a significant challenge to daily living, workplace productivity, and healthcare systems. Extant research supports empirical links between anxiety and brain-level error monitoring. The ERN – or error-related negativity – is one widely studied correlate of anxious symptomatology. Relatively stable individual differences in the ERN are inferred from electroencephalogram (EEG) recordings time-locked to the commission of mistakes. However, the assumed interchangeability of ERNs elicited under different experimental conditions has not been thoroughly evaluated. Canonical tasks for measuring the ERN may cue specific strategies for cognitive control, possibly producing divergent findings across studies. In a sample of 108 undergraduate …


Formalizing The Faustian Bargain Within The Healthcare Domain: An End-Of-Life Approach., Rachel Appel Dec 2023

Formalizing The Faustian Bargain Within The Healthcare Domain: An End-Of-Life Approach., Rachel Appel

Electronic Theses and Dissertations

A Faustian Bargain refers to an individual making a “deal with the devil,” exchanging something moral or sacred for an unattainable earthly good. The Faustian Bargain has been used to describe a ubiquitous social dilemma inherent to human civilization: exchanging individual liberty for public goods (e.g., security) provided by societal leaders and governments (Ostrom, 1980). Research on Faustian Bargains often examines tradeoffs between outcome utility (i.e., value derived from the outcomes of a decision) and procedural utility (i.e., value derived from being involved in the decision process (e.g., Frey et al., 2004). Much of the research on Faustian Bargains has …


Biomarkers Of Objective Criteria For Subtle Cognitive Decline In Parkinson’S Disease, Mary Ellen Garcia Dec 2023

Biomarkers Of Objective Criteria For Subtle Cognitive Decline In Parkinson’S Disease, Mary Ellen Garcia

Electronic Theses, Projects, and Dissertations

Mild cognitive impairment in Parkinson’s disease (PD-MCI) is the continuum from normal cognitive function to dementia. Recent studies suggest that objectively defined subtle cognitive decline (Obj-SCD), which uses non-traditional “process” neuropsychological scores, may be a better pathway to earlier detection of cognitive impairment. Obj-SCD has been defined as the stage where cognition is not impaired, but biomarkers are present or cognitive impairment is minimal but not sufficient to meet MCI or dementia criteria. We examined the longitudinal trajectories of neurodegenerative markers among individuals who are classified as cognitive normal (CN), Obj-SCD, and PD-MCI. Past literature has been inconsistent about the …


The Relationship Between Auditory Working Memory And Statistical Learning In Infancy, Mckenzie Mullins Sheets Dec 2023

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 …


Discounting Of Delayed And Probabilistic Outcomes Across The Adult Lifespan, Haoran Wan Dec 2023

Discounting Of Delayed And Probabilistic Outcomes Across The Adult Lifespan, Haoran Wan

Arts & Sciences Electronic Theses and Dissertations

Intertemporal and risky decision-making predicts many problem behaviors that also decline with age, raising the question: Do intertemporal and risky decisions change with age? Despite the theoretical and empirical importance, the literature under both rubrics reveals inconsistent findings. Some studies suggest that these inconsistencies may be due to the presence of unassessed demographic differences. The present study examined age differences, evaluating the role of demographic variables in intertemporal and risky choice of gains and losses using the discounting framework. Four experiments were conducted, each with one of the four types of discounting: discounting of delayed gains, discounting of delayed losses, …


Diagnostic Feature Detection And Sequential Eyewitness Lineups, Jerome D. Hoover Nov 2023

Diagnostic Feature Detection And Sequential Eyewitness Lineups, Jerome D. Hoover

Masters Theses

Prior work has demonstrated that the sequential presentation of lineup members in eyewitness lineups can result in undesirable position effects. For example, some studies have shown that placing the suspect in later positions increases discriminability. However, the evidence for this late-position discriminability advantage is mixed and the processes by which the discriminability increase occurs are unclear. However, one theory in particular, diagnostic feature detection theory (DFDT) explicitly predicts a late-position discriminability increase. According to DFDT, because shared features across lineup members cannot be used as reliable recognition cues to guide identification, discounting these features from consideration improves recognition. In sequential …


Not All Numbers Were Created Equal: Evidence The Number One Is Unique, Jenna L. Croteau Nov 2023

Not All Numbers Were Created Equal: Evidence The Number One Is Unique, Jenna L. Croteau

Masters Theses

Universally across modern cultures children acquire the meaning of the words one, two, and three in order. While much research has focused on how children acquire this knowledge and what this knowledge represents, the question of why children learn numbers in order has been comparatively neglected. To address this question, a non-verbal anticipatory looking task was implemented. In this task, 35 14- to 23-month-old infants were assessed on their ability to form implicit category structures for the numbers one, two, and three. We hypothesized that children would be able to form the implicit category structure for the number one …


Do I Listen To You, Or Do I Listen To Me? An Individual Difference Investigation Into Advice Utilization, Danielle Nicole Sanchez-Combs Nov 2023

Do I Listen To You, Or Do I Listen To Me? An Individual Difference Investigation Into Advice Utilization, Danielle Nicole Sanchez-Combs

Psychology ETDs

This work addresses three fundamental questions. First, can the source of the advice (crowd or single advisor) be leveraged to enhance advice use? Second, does high skill and high metacognitive ability predict greater advice use or are these individuals also blind to the need for advice? Finally, can personality, performance, and pre-advice confidence factors be used to profile those most likely to benefit from advice? Results indicated surprisingly low advice taking rates (~25% to ~26%) from both advisors, despite the advice being 100% accurate. Advice taking was even lower when individuals were in a high-confidence state, with high-skilled …


Diet And The Role It Plays In Cognition, Ryan S. Lavrisa Oct 2023

Diet And The Role It Plays In Cognition, Ryan S. Lavrisa

Honors College Theses

The Food and Agricultural Organization of the United Nations have calculated the effects of animal agriculture and factory farming to be responsible for generating 14.5-16.5% of global greenhouse gas emissions as well as using 70% of all agricultural land to sustain itself. Plant-based diets such as veganism and vegetarianism have been on the rise as many seek to find diets that mitigate the animal suffering and environmental impact for which animal agriculture is responsible. With the rise of these diets, it is important to understand the cognitive effects adhering to such diets can have on the body and mind, as …


Quantifying Neuromelanin Content Across Varying Magnetic Field Strengths: A Comparative Analysis, Laiba Rizwan Oct 2023

Quantifying Neuromelanin Content Across Varying Magnetic Field Strengths: A Comparative Analysis, Laiba Rizwan

Electronic Thesis and Dissertation Repository

Neuromelanin (NM) is an insoluble dark pigment molecule that is found in the substantia nigra of the human brain. Due to its paramagnetic nature, NM can be imaged using MRI in the form of neuromelanin sensitive contrast. This method, known as Neuromelanin Sensitive Magnetic Resonance Imaging (NM-MRI) allows non-invasive imaging of the human substantia nigra through its by-product, NM. NM-MRI research has been mostly done using lower field strength (3 or 1.5 Tesla) MRI scans. The advent of high field strength imaging, e.g., 7 Tesla (7T) provides the opportunity to study neuromelanin production sites with higher spatial resolution and enhanced …


Exploring The Effectiveness Of Mood Induction In Virtual Reality, Julia V. Ignaszewski Oct 2023

Exploring The Effectiveness Of Mood Induction In Virtual Reality, Julia V. Ignaszewski

Electronic Thesis and Dissertation Repository

Mood induction procedures (MIPs) are commonly used by researchers who seek to examine affective states and their effects on other outcomes of interest. Despite their popularity, MIPs do not generate the same type of intense and influential emotions that are caused by life events, creating an empirical gap between naturalistic and experimentally manipulated emotion. Researchers have begun exploring the use of virtual reality (VR) to address these flaws, as its engaging and immersive nature could confer higher ecological validity for laboratory-induced emotions. This study compared the effectiveness of fear-elicitation via a VR cinema MIP to that of a standard film …


Investigating The Language Of Time: Evaluating The Use And Comprehension Of Before And After, Kimberley R. Henderson Oct 2023

Investigating The Language Of Time: Evaluating The Use And Comprehension Of Before And After, Kimberley R. Henderson

Electronic Thesis and Dissertation Repository

Before-initial sentences are thought to be more difficult to comprehend than after-initial sentences because they structurally mismatch the temporal order of real-world events (Münte et al., 1998). Although event knowledge is known to affect how people understand before/after-initial sentences, little is known about the role of language knowledge in comprehending these sentences. A corpus analysis of before/after-initial sentences revealed that before typically is paired with a pronoun (Before he…) whereas after is paired with verb-ing (After leaving…). Participants' eyes were tracked while they read Before/After-pronoun/verbing sentences. Reading times did not match the …


Resting-State Functional Connectivity Correlates Of Attentional Bias In An Emotional Free Viewing Paradigm: An Eye-Tracking Investigation, Andrew Hauler Oct 2023

Resting-State Functional Connectivity Correlates Of Attentional Bias In An Emotional Free Viewing Paradigm: An Eye-Tracking Investigation, Andrew Hauler

All NMU Master's Theses

Threat detection, the process of searching complex environments for harmful stimuli, represents a vastly important job that promotes the biological fitness of the organism. Decades of experimental evidence suggests individuals either diagnosed, or at risk for, affective disorders display altered patterns of attentional engagement (hypervigilance or maintenance) with external stimuli; referred to as attentional biases. To date, the extent to which underlying neural mechanisms drive attentional biases, both in affective disorders as well as unselected populations, remain to be resolved. Thus, using eye-tracking and a passive emotional free viewing task, this study set to clarify resting-state network contributions from three …


The Self-Reference Effect On Memory Among 4- To 6-Year-Olds: The Role Of Active Encoding And Cognitive Abilities, Alicia Nicole Bartlett Sep 2023

The Self-Reference Effect On Memory Among 4- To 6-Year-Olds: The Role Of Active Encoding And Cognitive Abilities, Alicia Nicole Bartlett

Electronic Theses and Dissertations

The self-reference effect (SRE) is the enhanced memory for information encoded with reference to oneself relative to information encoded with reference to another non-intimate person or the linguistic properties of a word (Rogers et al., 1977). This effect is measured with an encoding task and a surprise recall and/or recognition task. An important distinction among encoding tasks is whether they involve active or passive engagement with the to-be-remembered information. Tasks with active engagement require the participant to identify the relation between the referent and target object and then to perform a mental (e.g., evaluate desirability of objects) or physical (e.g., …


Exploring The Relationship Between Of Subjective And Objective Cognition Among Older Adults Living In Canada, Astrid Dawn Coleman Sep 2023

Exploring The Relationship Between Of Subjective And Objective Cognition Among Older Adults Living In Canada, Astrid Dawn Coleman

Electronic Theses and Dissertations

The older adult population in Canada is growing rapidly, increasing the prevalence and burden of conditions that impact these individuals, such as dementia. Given that early detection and intervention are strongly associated with better disease outcomes, understanding the progression from healthy aging to dementia is critical. Two factors contributing to disease progression are cognitive impairment on objective neuropsychological measures and subjective cognitive complaints. However, the association between individuals’ perceptions of their cognitive abilities and their performance on cognitive tests remains unclear. Therefore, the goal of this project was to gain insight into the relationship between subjective and objective cognitive functioning …


Investigating Visual Vigilance Following Chronic Behavioural Immune System Activation, Jessica Hurtubise Sep 2023

Investigating Visual Vigilance Following Chronic Behavioural Immune System Activation, Jessica Hurtubise

Electronic Theses and Dissertations

The behavioural immune system (BIS) is a coordinated set of cognitive, affective, and behavioural responses that minimize pathogen contact. Prior to the COVID-19 pandemic, the majority of research on the BIS was limited to situations of acute pathogen threat. These studies identified that personal predispositions and environmental stimuli interact and lead to cognitive changes, including perceptual enhancements and attentional biases, as well as sensations of disgust. The cognitive and affective changes that follow pathogen exposure motivate pathogen avoidance behaviours and reduce the risk of infection. The BIS is highly adaptive in the context of acute pathogen threat, but less is …


The Neural Correlates Of Bodily Self-Consciousness In Virtual Worlds, Evan A. Owens Sep 2023

The Neural Correlates Of Bodily Self-Consciousness In Virtual Worlds, Evan A. Owens

Dissertations, Theses, and Capstone Projects

Bodily Self-Consciousness (BSC) is the cumulative integration of multiple sensory modalities that contribute to our sense of self. Sensory modalities, which include proprioception, vestibulation, vision, and touch are updated dynamically to map the specific, local representation of ourselves in space. BSC is closely associated with bottom-up and top-down aspects of consciousness. Recently, virtual- and augmented-reality technology have been used to explore perceptions of BSC. These recent achievements are partly attributed to advances in modern technology, and partly due to the rise of virtual and augmented reality markets. Virtual reality head-mounted displays can alter aspects of perception and consciousness unlike ever …


Brainwaves, Memory, And Reward, Rebecca Mccune Sep 2023

Brainwaves, Memory, And Reward, Rebecca Mccune

Dissertations, Theses, and Capstone Projects

The development of effective educational curricula for enhancing learning involves the crucial consideration of effort and rewards. In the realm of education, teachers commonly employ rewards as motivational tools. Traditionally, these rewards are given to students as a recognition of their successful performance. However, a thought-provoking idea emerges: What if we were to extend rewards to students not solely based on accurate answers, but also on the effort they invest, even in cases where their actual response might be incorrect? Our study explores the potential impact of this approach on the way information is absorbed and subsequently retained, specifically focusing …


The Effects Of Isolated Affordances On Preschool Counting Improvement When Using A Digital Coloring App, Katherine Papazian Sep 2023

The Effects Of Isolated Affordances On Preschool Counting Improvement When Using A Digital Coloring App, Katherine Papazian

Dissertations, Theses, and Capstone Projects

Counting is an important preschool math skill that is necessary for building a strong foundation in mathematics. Previous research has demonstrated that guided counting activities can improve counting ability in preschoolers and that drawing on paper while learning can deepen processing, but research has not included digital drawing as a potential means of deepening processing while children count. This study developed a novel touch-screen app, which used a guided coloring activity to encourage effective counting skills and serve as a home numeracy tool that could be employed by all parents, including those with math anxiety. To evaluate the benefits of …

Investigating Neural Mechanisms Associated With The Double Empathy Problem Using Fnirs Hyperscanning, Kate E. Turner Aug 2023

Investigating Neural Mechanisms Associated With The Double Empathy Problem Using Fnirs Hyperscanning, Kate E. Turner

Electronic Thesis and Dissertation Repository

The Double Empathy Problem posits that autistic social difficulties are due to differences in communication styles rather than an autistic deficit in theory of mind (ToM). We used fNIRS hyperscanning to examine whether neural synchrony in pairs with varying levels of autistic traits during social interactions supports the Double Empathy Problem. Participants with low and high autistic trait expression were paired creating High-High, Low-High, and Low-Low groups. Pairs completed two trials where they 1) listened to and 2) discussed stories that contained or lacked theory of mind elements, while brain activity was recorded within the ToM network. During conversation, High-High …


Nutrition As A Modifiable Risk Factor For Cognitive Decline: Associated Cognitive And Physical Health Changes, Taylor Mcmillan Aug 2023

Nutrition As A Modifiable Risk Factor For Cognitive Decline: Associated Cognitive And Physical Health Changes, Taylor Mcmillan

Electronic Theses and Dissertations

Dementia is defined as gradual, progressive loss of cognitive functioning, greater than what is expected of normal aging, resulting in functional impairment. There are several types of dementia clinical syndromes that are accompanied by unique patterns of cognitive dysfunction and neuropathological changes. Alzheimer’s disease (AD) is the most common type of clinical dementia syndrome, accounting for approximately 60-70% of cases. Neuropathological mechanisms associated with AD include the disruption of the cholinergic system, accumulation of amyloid-beta plaques and hyperphosphorylated tau, as well as vascular pathology. Vascular pathology complicates the characterization of clinical and neuropathic changes in AD, as there becomes significant …


Oral Contraception And Cognition, Kathleen Gerencer Aug 2023

Oral Contraception And Cognition, Kathleen Gerencer

Electronic Theses and Dissertations

Oral contraception is currently used by over 100 million women worldwide. Women utilize contraception not only to prevent pregnancy but also to manage a wide range of health concerns, such as acne and polycystic ovarian syndrome. Although this medication has granted women bodily autonomy, helped them attain higher levels of education, and helped them enter the workforce in greater numbers, little is known about the consequences outside of the intended contraceptive effects, specifically the cognitive and behavioral consequences. Moreover, because doctors can prescribe contraception after the first menstrual cycle and during puberty, it’s possible that this critical window of development …


Spontaneous Intrapersonal Synchrony And The Effect Of Cognitive Load, Ramkumar Jagadeesan Aug 2023

Spontaneous Intrapersonal Synchrony And The Effect Of Cognitive Load, Ramkumar Jagadeesan

Electronic Thesis and Dissertation Repository

Spontaneous intrapersonal synchronization is the spontaneous synchronization of periodic behaviors within an individual. It is less investigated than spontaneous interpersonal synchronization, the synchronization of periodic behaviors that occurs spontaneously between individuals integrated into a single system through coupling, caused by the exchange of sensory feedback between them. It was therefore hypothesized that periodic behaviors produced by an individual, a single system by default, would spontaneously be more synchronous through exchange of sensory feedback, coupling and integration within the individual, when the behaviors are produced simultaneously, compared to separately. Based on a postulate that explains spontaneous interpersonal synchronization as a strategy …


Fraction Magnitude Understanding Across Learning Formats: An Fmri Study, Chloe A. Henry Aug 2023

Fraction Magnitude Understanding Across Learning Formats: An Fmri Study, Chloe A. Henry

Electronic Thesis and Dissertation Repository

Knowledge of fraction magnitudes are an important, but notoriously difficult mathematical concept to master. Behavioural work has begun to explore and compare the instructional tools used for fraction learning. However, how fraction instructional tools are processed in the brain remains an underexplored question. Therefore, in the present thesis, we used functional brain MRI methodology to examine the neural activity of adult participants while completing a fraction verification task using the number line and area model, two common methods of fraction learning. We found that both models commonly recruited fronto-parietal activity, the neural regions typically implicated in number processing. However, we …
