    Psychophysics as a Science of Primary Experience.Jiří Wackermann - 2010 - Philosophical Psychology 23 (2):189 – 206.
    In Fechner's psychophysics, the 'mental' and the 'physical' were conceived as two phenomenal domains, connected by functional relations, not as two ontologically different realms. We follow the path from Fechner's foundational ideas and Mach's radical programme of a unitary science to later approaches to primary, psychophysically neutral experience (phenomenology, protophysics). We propose an 'integral psychophysics' as a mathematical study of law-like, invariant structures of primary experience. This approach is illustrated by a reinterpretation of psychophysical experiments in terms of perceptual situations (...)

    Dyadic Correlations Between Brain Functional States: Present Facts and Future Perspectives.J. Wackermann - 2004 - Mind and Matter 2 (1):105-122.
    For about four decades data suggestive of correlations between functional states of two separated brains, not mediated by sensory or other known mechanisms, were reported, but the experimental evidence is still scarce and controversial. In this paper we briefly review studies in which one member of a pair of human subjects was physically stimulated and synchronous correlates were searched for in the brain electrical activity of the other, non-stimulated subject. We give a comprehensive account of our study of dyadic EEG (...)

    Measure of Time: A Meeting Point of Psychophysics and Fundamental Physics.J. Wackermann - 2008 - Mind and Matter 6 (1):9-50.
    In the present paper the relation between objective and subjective time is studied from a neutral non-dualist perspective Adoption of the relational concept of time leads to fundamental problems of time measurement of the uniformity of time measures, and of a native measure of duration in subjective experience. Experimental data on discrimination and reproduction of time intervals are reviewed and relevant models of internal time representations are discussed. Special attention is given to the 'dual klepsydra model' (DKM)and to the outstanding (...)

    Flicker-Light Induced Visual Phenomena: Frequency Dependence and Specificity of Whole Percepts and Percept Features.Carsten Allefeld, Peter Pütz, Kristina Kastner & Jiří Wackermann - 2011 - Consciousness and Cognition 20 (4):1344-1362.
    Flickering light induces visual hallucinations in human observers. Despite a long history of the phenomenon, little is known about the dependence of flicker-induced subjective impressions on the flicker frequency. We investigate this question using Ganzfeld stimulation and an experimental paradigm combining a continuous frequency scan with a focus on re-occurring, whole percepts. On the single-subject level, we find a high degree of frequency stability of percepts. To generalize across subjects, we apply two rating systems, a set of complex percept classes (...)
