Nested Structure Of Time Consciousness And Its Dependence On Mental Time Travel Competence And Episodic Memory

Dural Ozer, Ozge 01 January 2013 (has links) (PDF)
The main objective of this master thesis is to clarify the nested structure in time consciousness, depending on mental time travel and episodic memory. Time consciousness, mental time travel and episodic memory are connected, and function depending on each other. Mental time travel ability enables us to imagine personal future events. Episodic memory allows us to travel mentally into both past and future. Similarity between remembering the past and imagining the future indicates that episodic memory system contribute to future-directed personal mental time travel competence, and justifies the relation between episodic memory and mental time travel into both past and future. Episodic memory requires autonoetic consciousness, which can be applied to mental time travel competence, and mental time travel is a function of episodic memory. Distinguishing humans and non-humans is a method to understand the role of episodic memory and mental time travel in time consciousness. Episodic memory and mental time travel indicate to a higher-level time consciousness in humans, because mental time travel, episodic memory, autonoetic consciousness and recursive language are unique to humans, while non-humans show future-directed acts, possess episodic-like memory, and communicate with limited ways. Time consciousness is derived from the notion of autonoetic consciousness and it is a sort of temporal consciousness which enables us to be conscious of ourselves who travels in time and aware of ourselves along the temporal line. Non-humans have a rudimentary form of time consciousness, even they are deprived of autonoetic consciousness.

Verbal Information Hinders Young Children's Ability to Gain Modality Specific Knowledge

Waters, Gillian M., Beck, S.R. 30 January 2015 (has links)
No / In two experiments, we investigated whether having prior experience of objects influenced young children's ability to solve a metacognitive search task, based on the objects' perceptual properties. In Experiment 1, 100 children (mean age 77months) chose whether to look or feel to locate one of two hidden balls (identifiable by sight or touch). Before choosing, children were told about the balls' perceptual properties (i.e. their colour and feel'), and/or saw and touched them, or had no pre-trial experience of them at all. Children who only had self-directed contact with the balls performed best, but children who heard the objects described by an adult performed relatively poorly. In Experiment 2, 116 children (mean age 72months) either heard only relevant, relevant and irrelevant, or no information about the objects before completing the task. Verbal descriptions of the balls (whether or not they contained irrelevant information) caused children difficulties.

Evaluation et développement d'un modèle de la mémoire épisodique reposant sur un processus de mise à jour égocentrée / Assessment and development of an episodic memory model based on the egocentric updating with self-motion process

Cerles, Mélanie 27 April 2015 (has links)
La mémoire épisodique donne la capacité de voyager mentalement dans son propre passé. En cela,elle permet de faire fi du temps qui passe pour pouvoir revivre des événements passés. Ce travail dethèse évalue l’hypothèse selon laquelle la mémoire épisodique et la sensation de revivre un événementpassé (i.e., conscience autonoëtique) sont basées sur une fluence dans la reconstruction de l’épisode,reconstruction impliquant une mise à jour égocentrée. Cette proposition est développée dans le modèlede Gomez et collaborateurs (Gomez, Rousset & Baciu, 2009) qui propose que la mise à jourégocentrée permette de ré-instancier un point de vue spatialisé égocentré sur l’évènement remémoré.Ce travail de thèse a amené de nouveaux arguments en faveur de ce modèle, en évaluant à la foisl’approche attributionnelle de la mémoire épisodique et le lien fonctionnel entre la mise à jourégocentrée en ligne et la mémoire épisodique. Une première série d’études met en évidence uneinfluence de la fluence du processus de mise à jour égocentrée sur la conscience autonoëtique.L’augmentation artificielle de la fluence de mise à jour égocentrée, lors de la reconnaissance,augmente le sentiment de conscience autonoëtique et ce uniquement lorsque la reconnaissanceimplique une reconstruction. Une seconde série d’études permet de mettre en évidence un effetd’interférence du processus de mise à jour égocentrée en ligne sur la récupération épisodique.Actualiser sa position dans l’espace lors d’un déplacement a beau être un processus automatique, celaralentit spécifiquement le rappel de source. Enfin, une étude impliquant des patients atteints de lamaladie d’Alzheimer, met en évidence une dissociation entre les compétences en mise à jourégocentrée chez ces patients. Ces résultats sont discutés dans le cadre du modèle de Gomez etcollaborateurs et en regard d’une conception incarnée et située de la cognition. / Episodic memory makes it possible to mentally travel back in our own past; it breaks the law of theunidirectionality of time, and allows us to mentally relive past events. The main goal of this work wasto investigate whether episodic memory and the subjective feeling of reliving a past event (i.e.,autonoetic consciousness) arise from the fluency of the reconstruction process of the event. Thisreconstruction would involve the process of egocentric spatial updating with self-motion. Thishypothesis was first developed in Gomez and colleagues' model (Gomez, Rousset, & Baciu, 2009) thatsuggests that egocentric updating re-instances an egocentric spatial point of view on the rememberedevent. The present work brings additional behavioral evidences to this model by assessing both theconception of attributional episodic memory and the functional link between online egocentricupdating with self-motion and episodic memory. A first set of studies showed that enhancingartificially the fluency of the egocentric updating process, during the recognition phase, increasedautonoetic consciousness. Moreover, such phenomenon only happened when recognition involved areconstruction process. A second set of studies showed that performing an online egocentric updatingwith self-motion interfered with remembering. Although the updating of its own position though selfmotionis automatic, it specifically slows down source recall. Finally, a last study showed adissociation between preservations of and deficits of egocentric spatial updating abilities in patientssuffering from Alzheimer's disease. The results of these studies are discussed in the context of Gomezand colleagues' model, and in terms of embodied and situated cognition.

An actual house

Gaard, Trina January 2022 (has links)
When having travelled one returns to, or revisits, a place. Unaware of the personal transformation that has occurred, one realizes the change when confronted with familiar things. In a desire to understand what objects and places mean to people, the project An actual house looks at three objects from a childhood home: a staircase, a window and a curtain and their relation to memory and autonomic consciousness. It reflects upon the importance of memory and imagination in art, architecture, and design - memory as well as imagination as a tool to create a different future. This art-practice-based work uses a hybrid form method. Exploring phenomenology trough writing, creating objects from memory and conveying the work to a perceptible form in a curated exhibition. It wants to contribute to a discussion on the relation between humans, objects and places in time.
