Many phenomena of preference construction demonstrate a violation of the rationality premise in classical economic theories. One of the most well-known examples of preference construction is the compromise effect. This puzzling anomaly can be rationalized by contextual deliberation (i.e., endogenous information retrieval/acquisition that can partially resolve utility uncertainty before choice). In this research, we investigate the empirical validity of this explanation by performing falsification tests for its necessary predictions and identifying it from other potential accounts. We conduct five experiments with more than 1,000 participants and show that the compromise effect can be positively mediated by response time and cannot be eliminated by context information, but it can be moderated by manipulating the level of deliberation (i.e., time constraint, preference articulation, task order). These findings are consistent with the predictions of the theory of contextual deliberation. We also show that, on average, contextual deliberation (as proxied by response time) can uniquely account for about half of the total compromise effect.

Xml Documents

XML is a widely used general-purpose annotation formalism for creating custom markup languages. XML annotations give structure to plain documents to interpret their content. To extract information from XML documents XPath and XQuery languages can be used. However, the learning of these dialects requires a considerable effort. In this context, the traditional Query-By-Example methodology (for Relational Databases) can be an important contribution to leverage this learning process, freeing the user from knowing the specific query language details or even the document structure. This chapter describes how to apply the Query-By-Example concept in a Web-application for information retrieval from XML documents, the GuessXQ system. This engine is capable of deducing, from an example, the respective XQuery statement. The example consists of marking the desired components directly on a sample document, picked-up from a collection. After inferring the corresponding query, GuessXQ applies it to the collection to obtain the desired result.

The Relationship

We investigated the relationship between familiarity, perceived ease of use, and attractiveness of graph designs in two target groups: experts and laymen in design. In the first study, we presented them with a variety of more or less common graph designs and asked them without any additional task to evaluate their familiarity, attractiveness, and perceived ease of use. They judged the familiarity and ease of use of the graphs similarly, but they differed in their attractiveness judgments. Familiarity and perceived ease of use appeared to predict attractiveness, but stronger for laymen than for designers. Laymen are attracted to designs they perceive as familiar and easy to use. Designers are attracted to designs between familiar and novel. In the second study, we asked designers and laymen to first perform an information retrieval task with the same graphs and then rate their attractiveness. Laymen’s appreciations remained the same, but the designers’ judgments of attractiveness were different from those in study 1. Correlational analyses suggest that their attractiveness judgments after use were affected not by actual usability but by perceived ease of use of the graphs.
