متن کاملMultidimensional Fechnerian Scaling: Probability-Distance Hypothesis
This research has been supported by NSF Grant SES-0001925. I am indebted to Hans Colonius for many helpful discussions and for critically reading the earlier version of this paper. I am grateful to Robin Thomas, Jean-Claude Falmagne, and three anonymous reviewers for helpful suggestions. In particular, Falmagne and one reviewer pointed out flaws in my initial treatment of the relationship betwe...
متن کاملThe intrinsic constraint model and Fechnerian sensory scaling.
The Intrinsic Constraint (IC) model of depth-cue integration (F. Domini, C. Caudek, & H. Tassinari, 2006) posits a strong link between perceived depth and depth discrimination, much like some Fechnerian theories of sensory scaling. K. J. MacKenzie, R. F. Murray, and L. M. Wilcox (2008) tested the IC model by examining whether two depth-matched pairs of stimuli are separated by equal numbers of ...
متن کاملThe Fechnerian idea.
From the principle that subjective dissimilarity between 2 stimuli is determined by their ratio, Fechner derives his logarithmic law in 2 ways. In one derivation, ignored and forgotten in modern accounts of Fechner's theory, he formulates the principle in question as a functional equation and reduces it to one with a known solution. In the other derivation, well known and often criticized, he s...
متن کاملA measure of auditory-visual integration efficiency based on fechnerian scaling
Auditory-visual integration efficiency (IE) is a presumed skill employed by subjects independently from their ability to extract information from auditory and visual speech inputs. Currently there are no established methods for determining a subject’s IE. Here we present a novel measurement technique to address this issue without requiring explicit assumptions about the underlying audiovisual p...
