The major aim is to determine the psychophysiological responses to stress and stress-management interventions and to examine the role of stress and stress-related psychophysiological mechanisms (e.g., cognitions, behaviors, and physiological stress responses) in both healthy and medical populations.

If idioms employed in codes of conduct could be as idiosyncratic as examples suggest, then to what extent did early modern language of vice, too, persist in this genre?

In comparing a selection of 18th-century histories to a representative sample of 19th-century histories of science, this project inquires: Which early modern vices persisted into the 19th century and to what extent were those vices embodied in anecdotes, conveyed through commonplaces, or symbolically…

To argue that people can control the relative contributions of goal-driven and stimulus-driven processes to decision-making and action selection.

This project analyzes to what extent hodegetical textbooks relied on each other in warning their readers against vicious habits, how much continuity their catalogs of vice displayed, and to what extent vices that persisted throughout the 18th and 19th centuries were associated with easy-to-remember…

Political scientists Rebekah Tromble and Michael Meffert (Leiden University) address the question why certain frames persist over time in the media while others fade away and still others disappear very quickly. They suggest an approach based in event-history methodologies for assessing the causes of…
