An experiment is reported where we explore whether people can effectively integrate quantitatively vague information. Subjects were first asked to assign numerical values to the terms much, slightly, larger, and smaller. In a separate session 1 week later, they were asked to solve linear syllogism problems such as A is slightly larger than B, C is...

Web usability is a somewhat elusive concept. We think most people would agree that there is no magic "formula" or set of rules to follow that will guarantee a usable web site in all circumstances. Consequently, it's critical to have a comprehensive "bag of tricks" for evaluating the usability of any given web site. The purposes of this SIG are to s...

The readability of twelve different fonts and sizes in the Microsoft Windows environment was studied. The specific fonts were Arial, MS Sans Serif, MS Serif, and Small Fonts. Their sizes ranged from 6.0 to 9.75 points. These were presented using black text on either a white or gray background and either bold or non-bold style. There were significan...

An electronic mail system (EMS) has been in operation within Digital Equipment Corporation now for several years. The function of the system is to help serve the internal communication needs of this geographically distributed corporation. In particular, the system was intended to increase the effectiveness of managers, although secretaries, enginee...

In order to provide a reliable measure of the similarity of uppercase English letters, a confusion matrix based on 1,200 presentations of each letter was established. To facilitate an analysis of the perceived structural characteristics, the confusion matrix was decomposed according to Luce’s choice model into a symmetrical similarity matrix and a...

Reports an error in the original article by Hersh and Caramazza (Journal of Experimental Psychology: General. Vol 105(3) Sep 1976, 254-276). On page 261, Equation 10 is written incorrectly. The correct equation is presented here. Tested the proposition that natural language concepts are represented as fuzzy sets of meaning components and that langu...

Tested the proposition that natural language concepts are represented as fuzzy sets of meaning components and that language operators (adverbs, negative markers, and adjectives) can be considered as operators on fuzzy sets. The application of fuzzy set theory to the meaning of phrases such as very small, sort of large, etc., was examined in 4 exper...

Relations of semantic distance to response latencies in similarity judgments, to reaction times in a same-different classification task, and to proximity of recall in a free recall task were investigated. A multidimensional analysis of the similarity judgments was used to determine semantic structure and distances for pairs of animal words chosen f...

Letter series completion problems varying along location of irrelevant relations (beginning, end, none) were presented to 24 Ss. A repeated-measures analysis of solution times and errors revealed that irrelevant relations at the beginning of series produced the longest latencies and the most errors. Using a pattern induction/sequence production mod...
