Naloxone increases electrophysiological measures of selective information processing in humans.

The effects of the opiate antagonist naloxone on electrophysiological measures of human selective attention were examined utilizing a paradigm which dissociates selective information processing from any concurrent processes of general arousal that may be present. Subjects were injected with naloxone (2 mg, i.v.) or placebo prior to performing a three-channel selective listening task. The measur...

Animation and learning: selective processing of information in dynamic graphics

Animation can provide learners with explicit dynamic information that is either implicit or unavailable in static graphics. However, the inclusion of temporal change in a visual display introduces additional and qualitatively different information processing demands. For learners to be successful in building high-quality mental models from animated instruction, they must extract thematically re...

Stochastic Fuzzy Discrimination Information Measure Cost Function in Image Processing

A new cost function based on stochastic fuzzy discrimination information measure is introduced in this paper. Focusing on their significant parts, this cost function is used to find the optimal value of threshold for denoising image. It is, in fact, an extension of fuzzy entropy cost function by the present author. Multivariable normal distribution is used for creating focus on significant part...

Caffeine and selective visual processing.

This work addressed five issues: a) Does caffeine modulate electroencephalogram (EEG) background activity in a manner consistent with the idea of cortical "arousal"? b) Is performance in a simple speeded task improved under caffeine? c) Is visual processing more selective under caffeine? d) Does caffeine affect sensory discrimination? and e) Does it affect motor processes? We presented 16 subje...

Selective web information retrieval

One of the main challenges in Web information retrieval is the number of different retrieval approaches that can be used for ranking Web documents. In addition to the textual content of Web documents, evidence from the structure of Web documents, or the analysis of the hyperlink structure of the Web, can be used to enhance the retrieval effectiveness. However, not all the queries benefit equall...
