preference judgments of sounde intensities : a comparison between sensory and preferential types of judgment (English)
Abstract [en]

Preference as a motivational concept was considered as an organismic disposition and a model which contained a region with three distinct points of preference was tested according to correspondence with.sensory data. The preference region was limited by an upper and a lower limit and in between there was a maximum point of preference. The experimental subjects were instructed to produce the three categories when stimuli consisted of simple sinusoidals.The experimental studies started with an exploratory experiment where the preference level was registered by a threshold technique and was followed by an experiment where the metric properties of the region were tested. The three categories were found to form an equidistant scale. The two following experiments could mostly be characterized as invariance studies över minor procedural changes. In the four experiments which followed,-changes in preference region were predicted from sensory laws e. g. temporal integration, equal loudnesscontours and adaptation. The predictions were all supported with minor exceptions.Finally, the independence assumption between the two ears was tested and the assumption was verified. The experimen-talresults showed that the preference region can bs considered as a limited part on the loudness continuum and that this region follows sensory or psychophysical principles of judgment.
