TQM AS A TOOL TO INQUIRE INTO CYCLIC STRUCTURES IN MENTAL TIMING
The taxonomic Time-quantum Model, TQM (Geissler, 1987), is part of a long history of attempts to locate elementary constituents of mental timing. Yet in several respects it diverges from its precedents: Most importantly, it relies on a net of taxonomic relations among facets of mental time as different as temporal thresholds, processing epochs, and perceived durations; it comprises constructs deliberately treated as provisional and subject to updating in a continual forth and back between theory and experiment; its primitives allow composition of second-order constructs yielding strictly testable predictions. Thus TQM is not a model in the usual sense, but resembles open conceptual systems that have proved to be vital for the formation of coherent fields in natural sciences. While previous contributions focused on fundamental methodological issues, the present paper provides an easy introduction intended to catalyze a broader use of TQM as a heuristic instrument for both experimental scrutiny and modeling. To encourage a fresh attack, care has been taken to include illustrating evidence from sources widely scattered in the literature.
