			The main topics of time and timing in psychology, cognitive  neuroscience and biology have been formulated already in the nineteenth  century. Unfortunately, time and timing as a challenging topic has been put to  rest for quite some time, but has become a central issue again during the last  years. It has become clear, that perceptual or cognitive processes can only be  understood if the dimension of time is taken more seriously. The reduction of  complexity in neuronal systems is for instance, achieved by temporal  integration mechanisms which are independent of the content of a percept or a  cognitive act but are presemantical operations. It is essential to distinguish  between content functions and logistical functions that provide  presemantically defined temporal frames for mental activity.
