How do we perceive time? 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
signals, feeling states as well as to self-consciousness, are constitutive mechanisms for the creation of subjective time.
Next to fundamental research on the relationship between the experience of time with cognitive processes and affect, we study how the sense
of time is modulated in altered states of consciousness such as in meditation or in drug-induced states as well as in neurological and
Related to conceptualizations of an intricate relationship between self-consciousness, mindfulness and
subjective time, we are conducting a series of experiments probing for changes in the duration of the subjective present
through mindfulness meditation experience. We are employing a battery of psychophysical tasks related to perception of sequence,
to the integration of metronome beats, and the perception of alternations in an ambiguous figure and we are investigating
whether effects of meditation on the subjective present are modulated through heart-rate variability and breathing rate as bodily parameters.
