Document Summary
Branch of psychology that deals with the relationships between physical stimuli and mental phenomena. How the properties of the physical world map to experience . The mapping is: not one-to-one, not linear, not homogeneous over the whole dynamic range of a physical continuum . Due to the limitations of nervous system elements . Brightness # of quanta per unit time/space. Loudness amplitude of waveform (colour, brightness, pitch, loudness are all psycho experienced from consciousness) (spectral energy distribution, quanta per unit time/space, frequency of fundamental, amplitude of waveform are all physical) The non-linear nature of the relationship between the physical world and experience was first written about by the mathematician gabriel cramer. Diminishing marginal return function first described by gabriel cramer. When the amount you have is low, a low amount is needed to make a difference. When the amount you have is high, a higher amount is needed to make a difference.
