In the information age, where all answers are just a click away, curiosity, the intrinsic drive to learn, becomes of paramount importance. How easy is it to prime for curiosity and what are its effects? What simple interventions can be used to enable curiosity-driven behaviors? We have conducted a large-scale study to address these questions,…

This article analyzes latent variable models from a cognitive psychology perspective. We start by discussing work by Tuerlinckx and De Boeck (2005), who proved that a diffusion model for 2-choice response processes entails a 2-parameter logistic item response theory (IRT) model for individual differences in the response data. Following this line…

In this reply the authors address comments by C. R. Cloninger (2008) related to their report (R. F. Farmer & L. R. Goldberg, 2008) on the psychometric properties of the revised Temperament and Character Inventory (TCI-R) and a short inventory derivative, the TCI-140. Even though Cloninger's psychobiological model has undergone substantial…

This article describes a general item response theory model for personality items that allows the information provided by the item response times to be used to estimate the individual trait levels. The submodel describing the item response times is a modification of Thissen's log-linear model and is based on the distance-difficulty hypothesis in…

We introduce a personality inventory designed to measure six major dimensions of personality derived from lexical studies of personality structure. The HEXACO Personality Inventory (HEXACO-PI) consists of 24 facet-level personality trait scales that define the six personality factors named Honesty-Humility (H), Emotionality (E), Extraversion (X),…

Following an introductory definition of "scientific ability and creativity", product-oriented, personality and social psychological approaches to studying scientific ability are examined with reference to competence and performance. Studies in the psychometric versus cognitive psychological paradigms are dealt with in more detail. These two…

Creative leadership calls for leaders to make full use of the analytical as well as the intuitive mind.

The paper describes a pilot program implemented by the Department of Educational Leadership and Cultural…

This chapter addresses the role of character development in the college experience, the dimensions that constitute it, and various methods to assess its outcomes.

The purpose of this article is to provide a foundation for the development of evidence-based guidelines for the assessment of personality disorders, focusing in particular on integrated assessment strategies. The general strategy recommended herein is to first administer a self-report inventory to alert oneself to the potential presence of…

With the increasing globalization of human resources practices, a commensurate increase in demand has occurred for multi-language ("global") personality norms for use in selection and development efforts. The combination of data from multiple translations of a personality assessment into a single norm engenders error from multiple sources. This…

In this overview of his research in personality theory, Cattell describes the play of people, situations, and, ideas enacted over 30 years in his University of Illinois laboratory. Establishing meaningful empirical measurement methods was the foundation for further research into many aspects of personality development. (BS)
