Mans interst in human brain clock long standing

Time is an essential component of our mental life. Hence, it is not surprising that for many years, philoso-phers and psychologists have been intrigued by the ques-tion of how time enters into our experiences and thus shapes our cognitions (Roeckelein, 2000). For example, the great philosopher Immanuel Kant (1787/1998) ar-gued that space and time are basic intuitions (“a priori Anschauungen”) that structure our cognition. In addition, he believed that time involves a more subjective intuition than does space (see Boring, 1957). Thus, among other things, the study of time perception derives from Kant' s proposal about time. The perception of time also attracted early psychophysicists (e.g., Mach, 1865; Vierordt, 1868) and has remained an active field of research in psychology up to the present day (see Grondin, 2001; Meck, 2003). More recently, time perception has become a major object of research in the field of the cognitive neurosciences (see Lewis & Miall, 2003; Nobre & O'Reilly, 2004)
