Distinct contributions of the fornix and inferior longitudinal fasciculus to episodic and semantic autobiographical memory

Autobiographical memory (AM) is multifaceted, incorporating the vivid retrieval of contextual detail (episodic AM), together with semantic knowledge that infuses meaning and coherence into past events (semantic AM). While neuropsychological evidence highlights a role for the hippocampus and anterior temporal lobe (ATL) in episodic and semantic AM, respectively, it is unclear whether these constitute dissociable large-scale AM networks. We used high angular resolution diffusion-weighted imaging and constrained spherical deconvolution-based tractography to assess white matter microstructure in 27 healthy young adult participants who were asked to recall past experiences using word cues. Inter-individual variation in the microstructure of the fornix (the main hippocampal input/output pathway) related to the amount of episodic, but not semantic, detail in AMs e independent of memory age. Conversely, microstructure of the inferior longitudinal fasciculus, linking occipitotemporal regions with ATL, correlated with semantic, but not episodic, AMs. Further, these significant correlations remained when controlling for hippocampal and ATL grey matter volume, respectively. This striking correlational double dissociation supports the view that distinct, large-scale distributed brain circuits underpin context and concepts in AM

Apperceptive patterning: Artefaction, extensional beliefs and cognitive scaffolding

In “Psychopower and Ordinary Madness” my ambition, as it relates to Bernard Stiegler’s recent literature, was twofold: 1) critiquing Stiegler’s work on exosomatization and artefactual posthumanism—or, more specifically, nonhumanism—to problematize approaches to media archaeology that rely upon technical exteriorization; 2) challenging how Stiegler engages with Giuseppe Longo and Francis Bailly’s conception of negative entropy. These efforts were directed by a prevalent techno-cultural qualifier: the rise of Synthetic Intelligence (including neural nets, deep learning, predictive processing and Bayesian models of cognition). This paper continues this project but first directs a critical analytic lens at the Derridean practice of the ontologization of grammatization from which Stiegler emerges while also distinguishing how metalanguages operate in relation to object-oriented environmental interaction by way of inferentialism. Stalking continental (Kapp, Simondon, Leroi-Gourhan, etc.) and analytic traditions (e.g., Carnap, Chalmers, Clark, Sutton, Novaes, etc.), we move from artefacts to AI and Predictive Processing so as to link theories related to technicity with philosophy of mind. Simultaneously drawing forth Robert Brandom’s conceptualization of the roles that commitments play in retrospectively reconstructing the social experiences that lead to our endorsement(s) of norms, we compliment this account with Reza Negarestani’s deprivatized account of intelligence while analyzing the equipollent role between language and media (both digital and analog)

On the Phases of Reism

Kotarbiński is one of the leading figures in the Lvov-Warsaw school of Polish philosophy. We summarize the development of Kotarbiński’s thought from his early nominalism and ‘pansomatistic reism’ to the later doctrine of ‘temporal phases’. We show that the surface clarity and simplicity of Kotarbiński’s writings mask a number of profound philosophical difficulties, connected above all with the problem of giving an adequate account of the truth of contingent (tensed) predications. The paper will examine in particular the attempts to resolve these difficulties on the part of Leśniewski. It will continue with an account of the relations of Kotarbińskian reism to the ontology of things or entia realia defended by the later Brentano. Kotarbiński’s identification of Brentano as a precursor of reism is, it will be suggested, at least questionable, and the paper will conclude with a more careful attempt to situate the Brentanian and Kotarbińskian ontologies within the spectrum of competing ontological views

Spectators’ aesthetic experiences of sound and movement in dance performance

In this paper we present a study of spectators’ aesthetic experiences of sound and movement in live dance performance. A multidisciplinary team comprising a choreographer, neuroscientists and qualitative researchers investigated the effects of different sound scores on dance spectators. What would be the impact of auditory stimulation on kinesthetic experience and/or aesthetic appreciation of the dance? What would be the effect of removing music altogether, so that spectators watched dance while hearing only the performers’ breathing and footfalls? We investigated audience experience through qualitative research, using post-performance focus groups, while a separately conducted functional brain imaging (fMRI) study measured the synchrony in brain activity across spectators when they watched dance with sound or breathing only. When audiences watched dance accompanied by music the fMRI data revealed evidence of greater intersubject synchronisation in a brain region consistent with complex auditory processing. The audience research found that some spectators derived pleasure from finding convergences between two complex stimuli (dance and music). The removal of music and the resulting audibility of the performers’ breathing had a significant impact on spectators’ aesthetic experience. The fMRI analysis showed increased synchronisation among observers, suggesting greater influence of the body when interpreting the dance stimuli. The audience research found evidence of similar corporeally focused experience. The paper discusses possible connections between the findings of our different approaches, and considers the implications of this study for interdisciplinary research collaborations between arts and sciences

On the Subject of Autism: Lacan, First-Person Writing, and Research

In his essay, Don’t Mourn for Us, Jim Sinclair describes autism as a “way of being.” He maintains there is “no normal child hidden behind the autism” and that “it colors every experience, every sensation, perception, thought, emotion, and encounter, every aspect of existence.” In an attempt to appreciate the depth of Sinclair’s statements, this thesis approaches autism as a “way of being” through the psychoanalytic theory of Jacques Lacan. By applying Lacan’s conceptual framework to first-person writing and scientific research, I lay an interdisciplinary foundation for the case I make. Although this project requires significant conceptual scaffolding across different epistemological systems, I consider how Lacanian theory possesses a unique capacity to conceive of autism as a way of being and to open new ways of approaching the source material. Implicitly, Sinclair asks that we consider the question of what it means “to be” – autistic, neurotypical, or otherwise. I approach this from the premise that an individual exists as a thinking being, or a “subject.” Because psychoanalysis is concerned with the constitutive role of the unconscious in structuring consciousness, this thesis invests substantial space in consideration of how the Lacanian subject is oriented around a fundamental lack. To this end, I return frequently to Lacan’s concept of objet a, understood as a representative of the subject’s lack in the perceptual realm that is itself lacking. Further, Lacan’s unique interpretation of Freud consists in placing language as the ultimate mediating structure of subjectivity; it both generates lack and establishes a system for mitigating it. One’s way of being is always a way of being in language.1 Given the predominant roles of language and social communication impairments in the DSM-V diagnostic criteria for autism, a main goal of this project is to consider how an autistic way of being entails a unique structuration of lack.2 Autism and psychoanalysis share a history that extends back to the origins of the diagnosis. I explore this history with a focus on how different psychoanalytic theories conceptualize the autistic subject and to what extent they honor or undermine Sinclair’s position. Contemporary Lacanian thinkers of autism do both. Unique to Lacan’s structural approach, the concept of the Other is inclusive of a radical alterity, yet also the system of language, the body, and certain aspects of the maternal and paternal functions. The subject is unthinkable apart from the Other. I suggest an autistic way of being is discernible in the autistic subject’s relation to each aspect of the Other. I find support for this claim in recent sensorimotor research. Referred to loosely as the movement perspective, this research suggests that differences in how autistic individuals move and perceive others is a “unifying characteristic” of autism.3 Importantly, the movement perspective is proactively inclusive of first-person knowledge. Read through Lacan’s conceptual framework, movement differences address the underlying mechanism of the autistic subject’s relation to the Other, and thus its way of being. Most fundamentally, this thesis is a work of theory that attempts to articulate something universal about being a subject, without simultaneously eliding what is unique about being an autistic subjec

A dialogue of traditions on the reality of mind: Thomas Nagel and Bernard Lonergan

The scientific picture of the world is one of invisible particles and empty space, but this is not the world of our everyday experience. How can we reconcile the scientific view of the world with the view from our ordinary perspective? This thesis puts Thomas Nagel and Bernard Lonergan into dialogue on the question of the mind’s place in the world. Coming from different philosophical traditions, both thinkers provide a bigger picture in which to place materialism and to assess its errors. Thomas Nagel criticises modern forms of materialism because they try to explain away the reality of our perspective by reducing it to physical events in a perspectiveless scientific picture. He criticises the fundamental conception of the physical world upon which these reductionist theories depend, a conception that had its origins in the seventeenth century scientific revolution and one which conceived of the physical world as having no place for subjects’ perspectives. In Lonergan’s opinion, the reduction of the human consciousness to mere physical events is the result of a truncated conception of objectivity. The reason for this mistaken conception is that we confuse two distinct kinds of knowing, which in turn is because of a mistaken cognitional theory. This thesis argues that Nagel makes some insightful contributions to the place of mind in the cosmos, but that he, like the reductive materialists that he criticises, is limited by a truncated conception of objectivity that prevents him grasping the nature of the mind. This suggests that future philosophies of mind need to examine their presuppositions more deeply and be open to dialogue with one of the less well-known traditions of philosophy in contemporary scholarship – the Aristotelian-Thomistic tradition, in which Lonergan worked

Beyond Media Borders, Volume 1

This open access book promotes the idea that all media types are multimodal and that comparing media types, through an intermedial lens, necessarily involves analysing these multimodal traits. The collection includes a series of interconnected articles that illustrate and clarify how the concepts developed in Elleström’s influential article The Modalities of Media: A Model for Understanding Intermedial Relations (Palgrave Macmillan, 2010) can be used for methodical investigation and interpretation of media traits and media interrelations. The authors work with a wide range of old and new media types that are traditionally investigated through limited, media-specific concepts. The publication is a significant contribution to interdisciplinary research, advancing the frontiers of conceptual as well as practical understanding of media interrelations. This is the first of two volumes. It contains Elleström’s revised article and six other contributions focusing especially on media integration: how media products and media types are combined and merged in various ways

Conservation GIS: Ontology and spatial reasoning for commonsense knowledge.

Dissertation submitted in partial fulfilment of the requirements for the Degree of Master of Science in Geospatial Technologies.Geographic information available from multiple sources are moving beyond their local context and widening the semantic difference. The major challenge emerged with ubiquity of geographic information, evolving geospatial technology and location-aware service is to deal with the semantic interoperability. Although the use of ontology aims at capturing shared conceptualization of geospatial information, human perception of world view is not adequately addressed in geospatial ontology. This study proposes ‘Conservation GIS Ontology’ that comprises spatial knowledge of non-expert conservationists in the context of Chitwan National Park, Nepal. The discussion is presented in four parts: exploration of commonsense spatial knowledge about conservation; development of conceptual ontology to conceptualize domain knowledge; formal representation of conceptualization in Web Ontology Language (OWL); and quality assessment of the ontology development tasks. Elicitation of commonsense spatial knowledge is performed with the notion of cognitive view of semantic. Emphasis is given to investigate the observation of wildlife movement and habitat change scenarios. Conceptualization is carried out by providing the foundation of the top-level ontology- ‘DOLCE’ and geospatial ontologies. Protégé 4.1 ontology editor is employed for ontology engineering tasks. Quality assessment is accomplished based on the intrinsic approach of ontology evaluation.(...

The Translocal Event and the Polyrhythmic Diagram

This thesis identifies and analyses the key creative protocols in translocal performance practice, and ends with suggestions for new forms of transversal live and mediated performance practice, informed by theory. It argues that ontologies of emergence in dynamic systems nourish contemporary practice in the digital arts. Feedback in self-organised, recursive systems and organisms elicit change, and change transforms. The arguments trace concepts from chaos and complexity theory to virtual multiplicity, relationality, intuition and individuation (in the work of Bergson, Deleuze, Guattari, Simondon, Massumi, and other process theorists). It then examines the intersection of methodologies in philosophy, science and art and the radical contingencies implicit in the technicity of real-time, collaborative composition. Simultaneous forces or tendencies such as perception/memory, content/ expression and instinct/intellect produce composites (experience, meaning, and intuition- respectively) that affect the sensation of interplay. The translocal event is itself a diagram - an interstice between the forces of the local and the global, between the tendencies of the individual and the collective. The translocal is a point of reference for exploring the distribution of affect, parameters of control and emergent aesthetics. Translocal interplay, enabled by digital technologies and network protocols, is ontogenetic and autopoietic; diagrammatic and synaesthetic; intuitive and transductive. KeyWorx is a software application developed for realtime, distributed, multimodal media processing. As a technological tool created by artists, KeyWorx supports this intuitive type of creative experience: a real-time, translocal “jamming” that transduces the lived experience of a “biogram,” a synaesthetic hinge-dimension. The emerging aesthetics are processual – intuitive, diagrammatic and transversal
