Self-regulation is a highly adaptive, distinctively human trait that enables people to override and alter their responses, including changing themselves so as to live up to social and other standards. Recent evidence indicates that self-regulation often consumes a limited resource, akin to energy or strength, thereby creating a temporary state of ego depletion. This article summarizes recent ev...

It is my pleasure to comment on Otto Laske's paper (Leonardo 23, No. 1, 53-66, 1990). I had the opportunity to read several published papers and preprints by Laske when preparing a one-day discussion on composition theory, which he recently was invited to chair at the Laboratoire Musique et Infonnatique de Marseille (MIM). As a computer scientist, I have been involved in research work with ethn...

Can gestures alter thought? Thinking about time is deeply interlinked with actions in space, and gestures are abstracted actions. Four experiments showed that gestures alter thinking about time. Participants heard the same speech accompanied by different gestures. The viewed gestures biased listeners toward circular or linear thinking, toward parallel or sequential thinking, toward moving-ego o...

The interaction between the use of Information and Communication Technology (ICT) and travel and transportation has been an important issue in transportation research. ICT may substitute work trips and enhances non-work travel. Particularly for social activity and travel behaviour existing studies suggest that ICT has complementary effects: ICT enhances social travel or increases efficiency in ...

Longitudinal relations among ego-resiliency (ER), effortful control (EC), and observed intrusive parenting were examined at 18, 30, and 42 months of age (Ns = 256, 230, and 210) using structural equation modeling. Intrusive parenting at 18 and 30 months negatively predicted EC a year later, over and above earlier levels. EC at 30 months mediated the negative relation between 18-month intrusive ...

Many behaviors that lead to worsened health outcomes are modifiable, social, and visible. Social influence has thus the potential to foster adoption of habits that promote health and improve disease management. In this study, we consider the evolution of the physical activity of 44.5 thousand Fitbit users as they interact on the Fitbit social network, in relation to their health status. The use...
