The underlying assumptions of Fechnerian scaling are complemented by an assumption that ensures that any psychometric differential (the rise in the value of a discrimination probability function as one moves away from its minimum in a given direction) regularly varies at the origin with a positive exponent. This is equivalent to the following intuitively plausible property: any two psychometric differentials are comeasurable in the small (i.e., asymptotically proportional at the origin…

Multidimensional Fechnerian scaling: pairwise comparisons, regular minimality, and nonconstant self-similarity
Stimuli presented pairwise for same-different judgments belong to two distinct observation areas (different time intervals and/or locations). To reflect this fact the underlying assumptions of
Multidimensional fechnerian scaling: perceptual separability
A new definition of the perceptual separability of stimulus dimensions is given in terms of discrimination probabilities. Omitting technical details, stimulus dimensions are considered separable if
The Fechnerian idea.
It is argued that neither the 2 derivations of Fechner's law nor the relation of this law to thresholds constitutes the essence of FECHner's approach, and the idea of additive cumulation of sensitivity values is seen, which lends itself to sweeping generalizations ofFechnerian scaling.

Multidimensional Fechnerian Scaling: Basics.
A Fechnerian metric derived from these assumptions is an internal (or generalized Finsler) metric whose indicatrices are asymptotically similar to the horizontal cross-sections of the psychometric functions made just above their minima.
Fechnerian metrics in unidimensional and multidimensional stimulus spaces
It is argued that for unidimensional stimulus continua, the proposed theory for subjective (Fechnerian) distances among stimuli in a continuous stimulus space of arbitrary dimensionality is close to the intended meaning of Fechner’s original theory.

It is shown that in order to derive the Weibull shape for the response time distribution in the instance theory of automaticity (G. D. Logan, 1988) by an asymptotic argument from the theory of
