ABSTRACT
A vector code is proposed as an operational mode in neuronal nets. It is conceived as a basis for reconstruction of perceptual space from a matrix of subjective differences. The latter are regarded as absolute values of differences between excitation vectors of a test and a background. Such differences are considered to determine reaction time: The greater the subjective difference is, the shorter the reaction time is. Measurement of reaction time is conceived to evaluate excitation vectors generated in neuronal nets. Dependence of reaction time on subjective difference in a color detection task can be explained using vector coding network. Within visual field areas occupied by figure and background in color-coding ensembles, four-dimensional excitation vectors are generated. Vector psychophysiology is a branch of psychophysiology based on a principle of vector coding in neuronal nets. A stimulus acting on an ensemble of neurons results in a particular magnitude of excitation in each member of the ensemble.
