The Role Of Gamma Oscillations And Cortical Inhibition In The Development Of Working Memory In Adolescence, Christopher P. Walker

Dissertations and Theses (Open Access)

Adolescence is a dynamic period of social, cognitive, and biological changes. In particular, working memory, the ability to actively encode and maintain information over a short period of time, develops early in childhood and gradually increases in capacity and stability during adolescence. The precise neurophysiological mechanism by which working memory capacity increases during adolescence is unclear. The objective of this investigation was to evaluate the role of cortical gamma-band (> 30 Hz) oscillations—which are associated with working memory in adults—for the development of working memory capacity in adolescents, and to identify the extent to which the temporal profile of gamma-aminobutyric …

Person-Level Sources Of Continued Influence Effect: The Roles Of Attention Control, Intolerance Of Ambiguity And Conservatism, Jinhao Chi

Dissertations

People continually rely on disinformation to make judgments after it is corrected or discredited. This phenomenon is termed the continued influence effect (CIE). Using a sample of 152 participants, the current study examined whether the CIE can be explained by a person’s political orientation, attention control (AC) levels, intolerance of ambiguity (IA) and need for specific closure (NSC). It was found that when political orientation was based on self-reports, the overall political conservatism did not predict the CIE (r = .13, p = .09) but economic conservatism did (r = .19, p < .05), suggesting that those with higher self-reported fiscally conservative attitudes may show more prolonged influence of disinformation. In addition, the overall AC levels did not predict the CIE (r = .08, p = .30), but the antisaccade scores reflecting the ability to inhibit automatic responses were a significant positive predictor of the CIE (r = .18, p < .05). Lastly, neither IA nor NSC significantly predicted the CIE (ps > .05). These findings were obtained with only one …

Implicit Memory And Online Advertisement Priming, Matthew L. Custard

Electronic Theses and Dissertations

Implicit Memory research has been investigating the attentional requirements needed for something to be encoded and accessible through implicit memory. So far, previous research has produced mixed results on attentional requirements for perceptual implicit memory, some studies citing evidence for the need of attention, others citing the opposite. As well, research has been consistent in producing results showing that conceptual implicit memory has higher attentional demands than that of its perceptual counterpart. Adopting Transfer-Appropriate Processing framework, the current paper investigates attention requirements for both a perceptual task (picture identification) and a conceptual task (category exemplar generation). Participants examine webpages with …

Individual Differences In Executive Function And Reappraisal: A Latent-Variable Analysis, Wei Xing Toh

Dissertations and Theses Collection (Open Access)

Cognitive reappraisal is an adaptive emotion regulation strategy that positively impacts various facets of adaptive functioning (e.g., interpersonal relations, subjective well-being). Although reappraisal implicates cognitive processing, a clear consensus concerning the cognitive underpinnings of reappraisal has not yet been reached. Therefore, we examined how executive function (EF)—i.e., three general-purpose control abilities comprising working memory, inhibition, and shifting—are associated with performance-based reappraisal ability and self-reported reappraisal frequency. Using a latent-variable approach, we found that the shared variance among EF tasks (i.e., common EF)—a general goal-management ability that facilitates the active maintenance of task goals—significantly predicted reappraisal ability, but not reappraisal frequency. …

Exploratory Learning Activities In The Physics Classroom: Contrasting Cases Versus A Rich Dataset., Campbell Rightmyer Bego

Electronic Theses and Dissertations

In exploratory learning, students engage in an exploration activity on a new topic prior to instruction. This inversion of the traditional tell-then-practice order has been shown to benefit learning outcomes, especially conceptual knowledge and preparation for future learning, but not always. In three studies, the current work examines whether the type of exploration activity impacts learning mechanisms and outcomes, on the topic of gravitational field in undergraduate physics classrooms. Activities using either contrasting cases (CC) or a rich dataset (RD) are compared in two instructional orders, explore-first (EF) and instruct-first (IF). Learning outcomes measured procedural knowledge, conceptual knowledge, and performance …

The Feedback-Related Negativity Is A Time-Dependent Brain Mechanism That Facilitates Aversive Learning: Implications For The Reinforcement Learning Frn Hypothesis, Eric Rawls

Graduate Theses and Dissertations

Organisms encode rewarding and aversive experiences through reinforcement learning, capitalizing on prediction errors (PEs), which adapt action strategies over time. Computational theories are explicit that PE signals should update action weights continuously over the course of a behavioral task, an important time-dependent variation that is eschewed in traditional neuroscience studies that average over large numbers of trials. I examined variation in reaction times and feedback-locked cortical activity over time as a function of PE to critically examine theories indicating that PE signals drive time-dependent learning. We recorded EEG while participants completed a novel reinforcement task that varied prediction error on …

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 …

Humor Improves Women’S But Impairs Men’S Iowa Gambling Task Performance, Jorge Flores‑Torres, Lydia Gómez‑Pérez, Kateri Mcrae, Vladimir López, Ivan Rubio, Eugenio Rodriguez

Psychology: Faculty Scholarship

The Iowa Gambling Task (IGT) is a popular method for examining real-life decision-making. Research has shown gender related differences in performance, in that men consistently outperform women. It has been suggested that these performance differences are related to decreased emotional control in women compared to men. Given the likely role of emotion in these gender differences, in the present study, we examine the effect of a humor induction on IGT performance and whether the effect of humor is moderated by gender. IGT performance and parameters from the Expectancy Valence Model (EVM) were measured in 68 university students (34 men; mean …

Self-Concept Clarity And The Bodily Self: Malleability Across Modalities, Sonia A. Krol, Rémi Thériault, Jay A. Olson, Amir Raz, Jennifer A. Bartz

Psychology Faculty Articles and Research

The self has fascinated scholars for centuries. Although theory suggests that the self-concept (cognitive self-understanding) and bodily self (pre-reflective awareness of one’s body) are related, little work has examined this notion. To this end, in Study 1, participants reported on self-concept clarity (SCC) and completed the rubber hand illusion (RHI), a paradigm in which synchronous (vs. asynchronous) stimulation between a prosthetic hand and one’s own hand leads one to “embody” the prosthetic hand. Whereas participants were equally susceptible to the RHI during synchronous stroking, low-SCC individuals were more vulnerable to the illusion during asynchronous stroking, when the effect is unwarranted. …

The Effect Of Task Interruptions And Reliable Cues On Detection Changes Within Dynamic Scenes, Kimberly N. Perry

Psychology Theses & Dissertations

Interruptions are a common problem for attention and pose a threat to visual task performance. The Memory for Goals (MFG) theory suggests that strongly and accurately encoded cues can assist the ability to resume a primary task after an interruption (Altmann & Trafton, 2002). Encoded cues can undergo an activation decay during an interruption and become forgotten. Currently, there has been limited research on how visual interruptions affect cued recall within a dynamic environment. Thus, the goal of the present study was to examine the effect of cuing and task interruptions on change detection within dynamic scenes. Undergraduate students watched …

The present study aimed to determine the effects of alcohol abuse and dependence in long term functioning of older adults who have experienced a moderate to severe traumatic brain injury. The research question being answered in the current study was if a history of alcohol abuse or dependence would worsen neuropsychological functioning in older adults who experienced at least one moderate to severe traumatic brain injury. Participants of the study were selected from the more extensive database provided by the Brain Aging in Vietnam War Veterans (DOD-ADNI) database. All participants were Vietnam War veterans between the ages of 61 and …

Heroic Consciousness, Scott T. Allison

Heroism Science

This article describes heroic consciousness – how heroes perceive, experience, and think about the world. I describe the transformation of consciousness from its pre-heroic state to its heroic state. Pre-heroic consciousness is characterized by nescient and maladaptive thinking, dualism, separation, mono-rationality, and a naïve sense of empowerment. Heroic consciousness is exemplified by nondualism, unity, transrationality, and the wisdom of tempered empowerment. Heroic consciousness is achieved via three routes: (1) traversing the hero’s journey, (2) effective use of specific spiritual practices, and/or (3) participation in hero training programs. I discuss the implications of heroic consciousness for individual and global well-being.

Derivational Development: Derivational Word Processing In Three English-Speaking Populations, Lisa Suzanne Kemp

LSU Doctoral Dissertations

Native-English speaking adults use morphological decomposition to understand complex words (e.g. farmer becomes farm-er). Whether decomposition is driven by semantic organization is still unclear. It is also unclear whether ESL adults and elementary age children use the same word processing strategies as native speaking adults. This study tested an identical experimental procedure across three English-speaking populations: native speaking adults, non-native speaking adults and elementary age children. The first task tested how readers use base and suffix information in complex words and nonwords when the word featured only a base word, only a suffix, both a base and …
