The Divided Self: Internal Conflict In Literature, Philosophy, Psychology, And Neuroscience, Yulia Greyman
The Divided Self: Internal Conflict In Literature, Philosophy, Psychology, And Neuroscience, Yulia Greyman
Dissertations, Theses, and Capstone Projects
This thematic project examines the notion of self-division, particularly in terms of the conflict between cognition and metacognition, across the fields of philosophy, psychology, and, most recently, the cognitive and neurosciences. The project offers a historic overview of models of self-division, as well as analyses of the various problems presented in theoretical models to date. This work explores how self-division has been depicted in the literary works of Edgar Allan Poe, Don DeLillo, and Mary Shelley. It examines the ways in which artistic renderings alternately assimilate, resist, and/or critique dominant philosophical, psychological, and scientific discourses about the self and its …
An Implementation Of Integrated Information Theory In Resting-State Fmri, Idan E. Nemirovsky
An Implementation Of Integrated Information Theory In Resting-State Fmri, Idan E. Nemirovsky
Electronic Thesis and Dissertation Repository
Integrated Information Theory (IIT) is a framework developed to explain consciousness, arguing that conscious systems consist of interacting elements that are integrated through their causal properties. In this study, we present the first application of IIT to functional magnetic resonance imaging (fMRI) data and investigate whether its principal metric, Phi, can meaningfully quantify resting-state cortical activity patterns. Data was acquired from 17 healthy subjects who underwent sedation with propofol, a short acting anesthetic. Using PyPhi, a software package developed for IIT, we thoroughly analyze how Phi varies across different networks and throughout sedation. Our findings indicate that variations in Phi …
Coupled Correlates Of Attention And Consciousness, Ravi Varkki Chacko
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 …

Global Consciousness: A Functionalist Neurophilosophical Perspective, Connor C. Bowen
Global Consciousness: A Functionalist Neurophilosophical Perspective, Connor C. Bowen
CMC Senior Theses
The purpose of this thesis is to explore a thought-provoking consequence of the functionalist theory of mind. Given the current organizational structure of Earth and field theories of consciousness in neuroscience, Earth is probably conscious. The argument is explored through an examination of the current organizational structure of Earth and field theories of consciousness in neuroscience, which leads to the conclusion that Earth is conscious. Various theories of mind have been proposed by neuroscientists and philosophers alike in an attempt to qualify what consciousness is and what provides the basis for consciousness to occur. Support, in the form of data …
The Fragmented Mind: Working Memory Cannot Implement Consciousness, Javier Gomez-Lavin
The Fragmented Mind: Working Memory Cannot Implement Consciousness, Javier Gomez-Lavin
Dissertations, Theses, and Capstone Projects
In both philosophy and the sciences of the mind there is a shared commitment to the idea that there is a center—the seat of consciousness, the source of deliberation and reflection, and the core of personal identity—in the mind. My dissertation challenges this deeply entrenched view. I review the empirical literature on working memory, psychology’s best candidate for the workspace of the mind, and argue that it is not a natural kind and cannot inform these central cognitive processes. This deflationary view directly imperils many naturalistic theories of consciousness that rely on working memory, which are reviewed in this project. …
Preserved Consciousness In The Absence Of A Cerebral Cortex, The Legal And Ethical Implications Of Redefining Consciousness And Its Neural Correlates: A Case For A Subcortical System Generating Affective Consciousness, Shadia Kawkabani
Williams Honors College, Honors Research Projects
Historically, the scientific and medical communities have taken a corticocentric view on consciousness, emphasizing the need for a cortex in producing the conscious experience. The preserved consciousness observed in hydranencephalic children and decorticated rats suggests that some form of consciousness may be produced by a subcortical network. The brainstem, a phylogenetically ancient and conserved brain structure, could serve as the major integrative machinery to produce this form of consciousness, which is called affective consciousness—the evolutionary antecedent to the reflective consciousness that allows humans to reflect on their experiences. The functional convergence of the brainstem with the amygdala, motor system, and …
A Realization Of Modernity: Case Studies In Connectivity And Time, Mari Gorman
A Realization Of Modernity: Case Studies In Connectivity And Time, Mari Gorman
Dissertations, Theses, and Capstone Projects
My stated goal in applying to The Graduate Center was to explore my previous research in diverse fields of study. This research, the result of a formal investigation of acting, was and still is centrally focused on the subject of relationship itself, relationships being what actors create. In pursuit of a greater understanding of the essential nature of relationship in practical terms, a self-organizing complex system that constitutes universal relationship was unexpectedly discovered. As such, this system has been shown to offer solutions to many outstanding problems in diverse areas of study. The Liberal Studies program track, Approaches to Modernity …
Reducing Subjectivity: Meditation And Implicit Bias, Diana M. Ciuca
Reducing Subjectivity: Meditation And Implicit Bias, Diana M. Ciuca
CMC Senior Theses
Implicit association of racial stereotypes is brought about by social conditioning (Greenwald & Krieger, 2006). This conditioning can be explained by attractor networks (Sharp, 2011). Reducing implicit bias through meditation can show the effectiveness of reducing the rigidity of attractor networks, thereby reducing subjectivity. Mindfulness meditation has shown to reduce bias from the use of one single guided session conducted before performing an Implicit Association Test (Lueke & Gibson, 2015). Attachment to socially conditioned racial bias should become less prevalent through practicing meditation over time. An experimental model is proposed to test this claim along with a reconceptualization of consciousness …
The Structure Of Consciousness, Lowell Keith Friesen
The Structure Of Consciousness, Lowell Keith Friesen
Open Access Dissertations
In this dissertation, I examine the nature and structure of consciousness. Conscious experience is often said to be phenomenally unified, and subjects of consciousness are often self-conscious. I ask whether these features necessarily accompany conscious experience. Is it necessarily the case, for instance, that all of a conscious subject's experiences at a time are phenomenally unified? And is it necessarily the case that subjects of consciousness are self-conscious whenever they are conscious? I argue that the answer to the former is affirmative and the latter negative.
In the first chapter, I set the stage by distinguishing phenomenal unity from other …
Quintessence Of Dust: Cognitive Neuroscience And An Actor's Process, Jason Christopher Davis
Quintessence Of Dust: Cognitive Neuroscience And An Actor's Process, Jason Christopher Davis
Dissertations, Masters Theses, Capstones, and Culminating Projects
This thesis examines theories provided by cognitive neuroscience and applies them to an actor’s process. In particular, this research addresses the subjectivity and intentionality of our consciousness and special as-if states of consciousness, supported by the work of John Searle and Antonio Damasio. The phenomenal feeling of character-model control is discussed and supported by the work of Thomas Metzinger. The paper also considers our relative understanding of mirror neurons and specifically their function in relation to intersubjectivity and their use for an actor’s creation and conveyance of character in rehearsal and performance. It examines Stanislavsky’s notion of emotional memory and …
