What drives the geeks? Linking computer enthusiasm to achievement goals

The personality construct of geekism is introduced as the tendency to act out one's need for cognition in the domain of computing technology. Achievement goal theory is introduced, and we ask, what drives geeks in terms of achievement. In a questionnaire study, it is shown that geekism is related to achievement motivation in imagined situations with technology. Need for cognition showed strong association with self-oriented achievement goals. A newly created scale for computer enthusiasm seems to reflect performance oriented achievement goal

Optimizing Usability Studies by Complementary Evaluation Methods

This paper examines combinations of complementary evaluation methods as a strategy for efficient usability problem discovery. A data set from an earlier study is re-analyzed, involving three evaluation methods applied to two virtual environment applications. Results of a mixed-effects logistic regression suggest that usability testing and inspection discover rather disjunctive sets of problems. A resampling analysis reveals that mixing inspection and usability testing sessions in equal parts finds 20% more problems with the same number of session

The impact of culture and recipient perspective on direction giving in the service of wayfinding

We examined how culture and recipient perspective affect direction giving during wayfinding. Participants from the United States and the Netherlands provided directions from starting locations to destinations for fictional recipients driving through a town (route perspective) or looking at a map of the town (survey perspective). US participants provided street names more frequently than did Dutch participants, whereas Dutch participants provided landmarks more frequently than did US participants. Moreover, US participants provided more cardinal descriptors when addressing listeners adopting a survey perspective relative to a route perspective but more landmarks and left-right descriptors when addressing listeners adopting a route perspective relative to a survey perspective. Participants from the Netherlands evinced a similar pattern with the important distinction that they mostly ignored cardinal terms, unless explicitly primed to do so and in a survey condition. In addition, this very low usage of cardinal terms seemed to be replaced by using more landmark descriptions. This study revealed remarkable flexibility in people's spatial descriptions but also stressed major differences in the use of spatial terms between US and Dutch participants

A Semantic Map for Evaluating Creativity

We present a semantic map of words related with creativity. The aim is to empirically derive terms which can be used to rate processes or products of computational creativity. The words in the map are based on association studies performed by human subjects and augmented with words derived from the literature (based on human raters). The words are used in a card sorting study to investigate the way they are categorized by human subjects. The results are arranged in a heat map of word relations based on a hierarchical cluster analysis. The cluster analysis and a principal component analysis provide a set of five to six clusters of items related to each other, and as clusters related to creativity. These clusters could form a basis for scales used to rate aspects of computational creativity
