Zeitwahrnehmung und Zeitbewusstsein
Wie nehmen wir Zeit wahr? Die Befunde des Zusammenhangs zwischen unseren Gefühlen und subjektiver Zeit, sowie Konzepte des Selbstbewusstseins
und der Körperwahrnehmung verbinden das Zeitbewusstsein eng mit emotionalen und körperlichen Zuständen. Neuronale Prozesse im insularen Kortex,
die verbunden sind mit Gefühlen, Körperzuständen und dem Ich-Bewusstsein, sind dabei konstitutiv für die Erfahrung von Zeit.
Neben grundlegenden Studien zum Verhältnis von Zeit, Emotionen und Körperzuständen in gewöhnlichen Bewusstseinszuständen wird die
subjektive Zeit in außergewöhnlichen Bewusstseinszuständen wie in der Meditation, durch Flotation-REST oder unter Drogeneinfluss untersucht sowie in
psychopathologischen Bewusstseinszuständen bei neurologischen und psychiatrischen Erkrankungen.

Exploring and Modifying the Sense of Time in Virtual Environments (VIRTUALTIMES)
The sense of time co-constitutes our subjective experience and embodied self-consciousness. It refers to the dimensions of passage of time (time passing by) and structure of time (serial order of events). Both can be disturbed under psychopathological conditions and give rise to a variety of psychopathological symptoms. VIRTUALTIMES will for the first time (1) provide a personalized and neuroadaptive virtual reality technology enabling the systematic variation of time experience, based on (2) the rigorous study of the sense of time in different psychopathological conditions including depression, schizophrenia and autism, and (3) neuroscientific measures that describe neural mechanisms which underlie our sense of time and validate both diagnostic differences and technological interventions. For that purpose, virtual reality scenarios and games will be developed from the starting point of the everyday scenario “waiting room”. We will systematically enrich the scenery both physically (objects) and socially (interaction partners). In the realm of time-based interventions
this will allow to manipulate passage of time (varying velocity of time flow) and structure of time (varying synchronicity of events). VIRTUALTIMES (1) will provide a diagnostic tool and innovative mental health technology that works in a highly individualized, easy-access, and easy-to-use application, (2) will foster new technological developments in the field of human-computer-interaction to improve personal wellbeing and intercultural communication in a global world, and (3) will initiate a radical shift both in empirical approaches to and our understanding of the sense of time as basic constituent of human subjectivity.
07/2019 - 12/2021: Changes in the temporal width of the present moment after meditation.
FUNDAÇÃO Bial with €39,000.- Investigators: Marc Wittmann (Freiburg), Stefan Schmidt (Freiburg), Karin Meissner (Coburg, München)
Based on conceptually understood effects of mindfulness meditation on self-consciousness, bodily processes, and the present moment we aim at experimentally measuring changes in the temporal extension of the subjective present with the metronome paradigm and correlated psychophysiological variables during meditation experience.
