Visual Modulation Of Resting State Α Oscillations, Kelly Webster, Tony Ro

Publications and Research

Once thought to simply reflect passive cortical idling, recent studies have demonstrated that α oscillations play a causal role in cognition and perception. However, whether and how cognitive or sensory processes modulate various components of the α rhythm is poorly understood. Sensory input and resting states were manipulated in human subjects while electroencephalography (EEG) activity was recorded in three conditions: eyes-open fixating on a visual stimulus, eyes-open without visual input (darkness), and eyes-closed without visual input (darkness). We show that α power and peak frequency increase when visual input is reduced compared to the eyes open, fixating condition. These results …

Visual Illusion Susceptibility In Dogs Using The Ebbinghaus-Titchener Illusion In A Spontaneous Choice Task, Nicolette Becker

Theses and Dissertations

In recent years, dogs have been a popular test subject when studying visual illusion susceptibility. Multiple studies have investigated whether animals perceive illusions as humans do, but few studies have evaluated dogs’ perception of illusory stimuli. In this thesis, we studied if dogs are visually susceptible to the Ebbinghaus-Titchener illusion when presented in a spontaneous choice task. Subjects were presented two visual images on a board, which had bologna pieces embedded in the stimuli. In control trials, two different sized bologna pieces were placed in the center of the images. In these control conditions, dogs were expected to choose the …

Examining Relations Between Executive Functions And Decoding: A Meta-Analytic Investigation, Teresa Ober

Dissertations, Theses, and Capstone Projects

Introduction: The Simple View of Reading (SVR) is one of several established models of reading that present decoding and linguistic comprehension as critical skills in the development of reading competencies. Previous research has highlighted the connection between reading comprehension and cognitive skills, including those which fall under the term of executive functions (EF; for a review, see Follmer, 2018). EF may also be critical in the development of decoding. According to the dual route model of word recognition (Coltheart, 2006), decoding involves two separable processes; the phonological route, involving encoding and retrieval of letter-sound associations (also called phoneme-to-grapheme correspondence rules), …

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 Use Of Infographics To Assess Context Processing, Beliz Hazan

Dissertations, Theses, and Capstone Projects

Among high-order cognitive functions is the use of context to enhance comprehension of language or visual scenes. Although use of context is known to be impaired in certain clinical populations (e.g., schizophrenia), no existing test adequately assesses this construct. To fill this gap, we developed and attempted to validate a test of context use that employed Infographics (information graphics), which requires the use of context to interpret visual displays. The primary hypothesis was that interpreting Infographics would be sensitive to context processing. We further hypothesized that different levels of cognitive processing (requiring basic perceptual, real-world application, or verbal reasoning), as …

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 …

Getting The Benefit Of The Doubt: The Effect Of Randomization Ratio On The Placebo Response, Taiki Matsuura

Dissertations, Theses, and Capstone Projects

Placebos are commonly employed in clinical trials as inactive treatments to which experimental treatments are compared against in order to control for psychological “noise.” Randomized double-blind placebo control studies are considered the “gold standard” in epidemiologic research because they can provide the strongest possible evidence of causation if designed correctly (Hulley, Cummings, Browner, & Grady, 2007). One phenomenon that poses a threat to the integrity of this evidence is the placebo response (PR), or referred to as the “placebo effect.” Expectancy is considered a central PR mechanism and boasts the most empirical support among all proposed mechanisms. Expectancy is not …

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 …

The Role Of Eyewitness Confidence And Prosecution/Defense Presentation In How Facial Composites Shape Juror Decision-Making, Rebecca E. Singh

Student Theses

Eyewitness testimony has been found to be an unreliable form of evidence (Loftus, Miller & Burns, 1978; Oswald & Coleman, 2007; Wells & Hasel, 2007; Loftus & Greenspan, 2017; Jaross, 2018; Wade, Nash, & Lindsay, 2018; Wixted, Mickes, & Fisher, 2018). Yet, this evidence is still used in the courts today, and, in fact, is perceived by jurors as important and compelling in comparison to other case factors (e.g., character evidence, physical evidence; Topp-Manriquez, McQuiston, & Malpass, 2014; Kabzińska, 2015). Additionally, eyewitnesses are sometimes requested to help create a facial composite of the suspect and, critically, these composites are then …

Exploring Innovation And Behavioral Flexibility In African Lions (Panthera Leo) And Snow Leopards (Panthera Uncia), Victoria L. O'Connor

Theses and Dissertations

Intelligence may have evolved to help animals problem-solve in their physical and/or social environments, which enables them to cope with changes in their environments. Humans can reduce wildlife conflict by understanding how species that face harsh environments assess a situation and alter their behavior. Tests for cognitive behavior aim to formulate clear behavioral criteria for inferring an animal’s mental processes. We designed a custom multi-access puzzle box (MAB) to present a simple and effective behavioral test for exploring innovation in two species, African lions (Panthera leo) and snow leopards (Panthera uncia). Despite being vastly underrepresented in …

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.

Language Access In Early And Late Spanish-English Bilinguals: An Erp Study, Lissete Gimenez-Arce

Student Theses

Research suggests that code-switching between two languages is possible because there is nonselective access to both languages, i.e., both languages are interdependent and stored in a shared lexicon. In this study, we used event-related brain potentials (ERPs) to measure the neural processes associated with language access, in particular, the ERP components: N200 and N400. Although previous studies have utilized these ERPs to investigate language access using interlingual homographs, i.e., words that look the same in two languages but have different meanings, these have focused on comparisons of monolingual and bilinguals. In contrast, we used a design that looked at Spanish …

Do Psychopathic Traits Influence Distractibility By Empathy-Eliciting Pictures?, Priya M. Reji

Student Theses

Empathy is a crucial component in forming interpersonal connections, and reflects the ability to share and understand the feelings of others. Psychopathy is often associated with a reduced ability to feel and display empathetic concern towards other people. The Response Modulation Hypothesis argues that such individuals have an attentional deficit, which makes it difficult for them to shift focus between stimuli, thus individuals who have high scores on the interpersonal-affective factor of psychopathy have an increased ability to ignore emotional stimuli that are goal-irrelevant. The current study investigated whether psychopathic traits would influence distractibility on an emotional Stroop (eStroop) task. …

Alpha Oscillations And Feedback Processing In Visual Cortex For Conscious Perception, Tony Ro

Publications and Research

Variability in perception between individuals may be a consequence of different inherent neural processing speeds. To assess whether alpha oscillations systematically reflect a feedback pacing mechanism for cortical processing during visual perception, comparisons were made between alpha oscillations, visual suppression from TMS, visual evoked responses, and metacontrast masking. Peak alpha oscillation frequencies, measured through scalp EEG recordings, significantly correlated with the optimum latencies for visual suppression from TMS of early visual cortex. Individuals with shorter alpha periods (i.e., higher peak alpha frequencies) processed visual information faster than those with longer alpha periods (i.e., lower peak alpha frequencies). Moreover, peak alpha …

Competitive Frontoparietal Interactions Mediate Implicit Inferences, Martijn E. Wokke, Tony Ro

Publications and Research

Frequent experience with regularities in our environment allows us to use predictive information to guide our decision process. However, contingencies in our environment are not always explicitly present and sometimes need to be inferred. Heretofore, it remained unknown how predictive information guides decision-making when explicit knowledge is absent and how the brain shapes such implicit inferences. In the present experiment, 17 human participants (9 females) performed a discrimination task in which a target stimulus was preceded by a predictive cue. Critically, participants had no explicit knowledge that some of the cues signaled an upcoming target, allowing us to investigate how …

“A” For Effort: Rewarding Effortful Retrieval Attempts Improves Learning From General Knowledge Errors In Women, Damon Abraham, Kateri Mcrae, Jennifer A. Mangels

Publications and Research

Previous research has shown that the prospect of attaining a reward can promote task engagement, up-regulate attention toward reward-relevant information, and facilitate enhanced encoding of new information into declarative memory. However, past research on reward-based enhancement of declarative memory has focused primarily on paradigms in which rewards are contingent upon accurate responses. Yet, findings from test-enhanced learning show that making errors can also be useful for learning if those errors represent effortful retrieval attempts and are followed by corrective feedback. Here, we used a challenging general knowledge task to examine the effects of explicitly rewarding retrieval effort, defined as a …

What Influences Language Impairement In Bilingual Aphasia? A Meta-Analytic Review, Ekaterina Kuzmina, Mira Goral, Monica Norvik, Brendan S. Weekes

Publications and Research

Patterns of language impairment in multilingual speakers with post-stroke aphasia are diverse: in some cases the language deficits are parallel, that is, all languages are impaired relatively equally, whereas in other cases deficits are differential, that is, one language is more impaired than the other(s). This diversity stems from the intricate structure of the multilingual language system, which is shaped by a complex interplay of influencing factors, such as age of language acquisition, frequency of language use, premorbid proficiency, and linguistic similarity between one’s languages. Previous theoretical reviews and empirical studies shed some light on these factors, however no clear …

A Defense Of Pure Connectionism, Alex B. Kiefer

Dissertations, Theses, and Capstone Projects

Connectionism is an approach to neural-networks-based cognitive modeling that encompasses the recent deep learning movement in artificial intelligence. It came of age in the 1980s, with its roots in cybernetics and earlier attempts to model the brain as a system of simple parallel processors. Connectionist models center on statistical inference within neural networks with empirically learnable parameters, which can be represented as graphical models. More recent approaches focus on learning and inference within hierarchical generative models. Contra influential and ongoing critiques, I argue in this dissertation that the connectionist approach to cognitive science possesses in principle (and, as is becoming …

Cognitive, Behavioral, And Situational Influences On Relapse To Smoking After Group Treatment For Tobacco Dependence, Sara E. Lunden, Jami C. Pittman, Neelam Prashad, Ria Malhotra, Christine Sheffer

Publications and Research

Socioeconomic disparities in treatment failure rates for evidence-based tobacco dependence treatment are well-established. Adapted cognitive behavioral treatments are extensively tailored to meet the needs of lower socioeconomic status (SES) smokers and dramatically improve early treatment success, but there is little understanding of why treatment failure occurs after a longer period of abstinence than with standard treatment, why early treatment success is not sustained, and why long-term treatment failure rates are no different from standard treatments. We sought to understand the causes of treatment failure from the perspective of diverse participants who relapsed after receiving standard or adapted treatment in a …

Exploring Obesity, Adhd Severity, And Disordered Eating Behavior Among College Students, Carolina Rozario

Dissertations and Theses

Obesity is a global epidemic because of the potential health risks. There is evidence that many obese individuals manifest persistent ADHD symptoms, and that both disorders increase risk for binge eating. Nevertheless, how obesity and ADHD may increase risk for binge eating work is unclear. Neuropsychological deficits are common to all disorders and may help to explain the relations observed. The aim of this study was to explore whether neuropsychological dysfunction, especially inhibitory control weaknesses, moderate the association between greater BMI and more severe ADHD and disordered eating behaviors. Thirty-nine undergraduate college students (27 females; Mean age = 20.77, SD …
