2 Multidimensional Signal Detection Theory
Multidimensional signal detection theory is a multivariate extension of signal detection theory that makes two fundamental assumptions, namely that every mental state is noisy and that every action requires a decision. The most widely studied version is known as general recognition theory (GRT). General recognition theory assumes that the percept on each trial can be modeled as a random sample ...
متن کاملA Note on a Multidimensional Searching Problem
Search involves deciding whether or ~_gt a given object is in a collection of objects. When repeated searches have to be made on the same collection, it is desirable to organize the collection into a structure that facilitates efkient searching. The cost !of this organ~g or prepro~~ng can be assumed to be insignificant if a large number of searches are to be performed. The binary searching meth...

15 صفحه اولSignal detection theory in the 2AFC paradigm: attention, channel uncertainty and probability summation
Neural implementation of classical High-Threshold Theory reveals fundamental flaws in its applicability to realistic neural systems and to the two-alternative forced-choice (2AFC) paradigm. For 2AFC, Signal Detection Theory provides a basis for accurate analysis of the observer's attentional strategy and effective degree of probability summation over attended neural channels. The resulting theo...
متن کاملThe Psychophysics of Sensor Fusion: a Multidimensional Signal Detection Analysis
Image fusion techniques take input from multiple single-band sensors and combine it to create a single multi-band image. While such processing offers to create imagery that is more information rich than that produced by single-band sensors, it may sometimes degrade the perceptual quality of the input content. Working within the context of Ashby and Townsend’s (1986) General Recognition Theory, ...
