The discovery of mirror neurons (e.g., Gallese et al., 1996) has reignited interest in theories that postulate a tight functional link between perception and action. According to these theories, perception and action share a common representational code, with actions coded in terms of the distal perceptual effects that they produce (Prinz, 1997). Accordingly, action representations should be ac...

This paper investigates the challenges of inter-organizational cooperation, understood here as the fulfillment of joint tasks. The focus is on challenges or constraints influencing the quality of actions, the performance and, in consequence, the outcome of efforts for the organizations involved. Findings suggest shortcomings on the organizational and the individual level and in different domain...

We describe a model for task-driven, naturallanguage-based human-robot interaction where the roles of the two participants are fully interchangeable, both at the conversational level and at the task level. This model provides a general treatment of joint-action dialogue, and also allows models based on the analysis of human-human joint-action dialogues easily to be implemented and evaluated. I....

Traditionally, communication has been defined as the intentional exchange of symbolic information between individuals. In contrast, the mirror system provides a basis for nonsymbolic and nonintentional information exchange between individuals. We believe that understanding the role of the mirror system in joint action has the potential to serve as a bridge between these two domains. The present...

The ability to coordinate our actions with those of others is crucial for our success as individuals and as a species. Progress in understanding the cognitive and neural processes involved in joint action has been slow and sparse, because cognitive neuroscientists have predominantly studied individual minds and brains in isolation. However, in recent years, major advances have been made by inve...

Recent work suggests that social interaction modulates the sensorimotor simulation of an observed action. Recording electroencephalograms during a triadic social interaction, we investigated the effects of two specific aspects of social interaction on action simulation: the recent history of interaction and the distribution of individual parts of a simple joint task between actors. Activation o...

An emerging branch of social cognitive neuroscience attempts to unravel the critical cognitive mechanisms that enable humans to engage in joint action. In the current experiment, differences in brain activity in participants engaging in solitary action and joint action were identified using whole brain fMRI while participants performed a virtual bar-balancing task either alone (S), or with the ...

Patellar tendon moment arm length (PTma) changes at different knee flexion angles have not been determined in invivo studies. We aimed to determine PTma in four different knee angles using Magnetic Resonance Imaging (MRI) topredict in vivo changes in the moment arm length from different knee angles during running.PTma was measured as the perpendicular distance from muscle–tend...
