My Blog "Sense of Time" on Psychology Today

Time perception

Altered states of consciousness

Self-consciousness

Drug effects and drug dependence


How do we perceive time? How is the subjective experience of time related to cognition, emotion, and body states?

Findings on the relationship between affect and time, together with recent conceptualizations on self- and body processes have connected time perception with emotional and bodily states. Neural processes in the insular cortex, which are related to body sensations, feeling states as well as to self-consciousness, are constitutive for the creation of subjective time.

Next to fundamental research on time perception I study how the sense of time is modulated in altered states of consciousness as well as in neurological and psychiatric conditions.

Zeitwahrnehmung

Außergewöhnliche Bewusstseinszustände

Selbst-Bewusstsein

Drogenwirkung und Drogensucht


Wie nehmen wir Zeit wahr? Wie ist das Bewusstsein von Zeit mit dem Denken, unseren Gefühlen und Körperzuständen verbunden?

Befunde einer Beziehung von Emotionen und Zeit, sowie Konzepte der Selbstwahrnehmung und von Körpervorgängen binden das Zeitbewusstsein an emotionale und körperliche Zustände. Neuronale Prozesse im insularen Kortex, verbunden mit Gefühlen, Körperzuständen und Selbstbewusstsein, sind konstitutiv für die Erfahrung von Zeit.

Neben der Grundlagenforschung zur Zeitwahrnehmung wird die subjektive Zeit in außergewöhnlichen Bewusstseinszuständen sowie in psychopathologischen Zuständen untersucht.
