Description
Book SynopsisPsychophysics is by definition mappings between events in the environment and levels of human sensory responses. In this text the methods of nonlinear dynamics, employing trajectories developed for simpler sensory modelling, are extended to classes of problems which lie at the interface between sensation and perception. A diversity of topics for which extensive empirical evidence exists are reformulated by writing their dynamics in terms of complex trajectories put into coupled lattices and into cascades of such lattices. Fundamental relationships between core processes of psychophysics in time and space, and recurrent quantitative or topological distortions of the physical world which arise in perception, are given a treatment which contrasts fundamentally with traditional linear equations in use since the 19th century.
Table of ContentsFundamental assumptions of nonlinear psychophysics; nonlinear psycho-physics, response surface identification, and cross-entropy; properties of nonlinear dynamics underlying the generation of cascades and fields; unidimensional cascades and the case of perceived time estimation; phase space changes and cascaded noise in fields; more fields generated from lattices in (n x n)rk evolutions; other field and cascade representations - isosimilarities, instabilities and inductions; postscript - psychophysics or events in the real brain?
