The concurrent presentation of multiple stimuli in the visual field may trigger mutually suppressive interactions throughout the ventral visual stream. While several studies have been performed on sensory competition effects among non-face stimuli relatively little is known about the interactions in the human brain for multiple face stimuli. In the present study we analyzed the neuronal basis o...

Recent magneto-encephalographic and electro-encephalographic studies provide evidence for cross-modal integration during audio-visual and audio-haptic speech perception, with speech gestures viewed or felt from manual tactile contact with the speaker's face. Given the temporal precedence of the haptic and visual signals on the acoustic signal in these studies, the observed modulation of N1/P2 a...

This paper aims to understand some of the mechanisms which dominate the phenomenon of knowledge diffusion in the process that is called ‘social learning’. We examine how knowledge spreads in a network in which agents interact by word of mouth. The social network is structured as a network graph consisting of agents (vertices) and connections (edges) and is situated on a wrapped cellular automat...

Social interaction patterns have long been a subject of great interest. Several recent studies (e.g., [3, 2]) have examined the influence of face-to-face and mediated (e.g., phone, text and online social networks) communication channels on employees’ mood, but since their motivation stemmed from professional productivity, they did not include interactions that occurred outside the working envir...

"You are invited to the Bauer mansion for dinner and to help solve a murder." Invitations like this one have been sent out by the millions, inviting friends and family to a multiplayer murder mystery party, often from the best-selling "How to Host a Murder" series of games. At these parties the players gather at a friend's house for dinner imagining it to be a mansion in the 1930's. The party g...

Organizing in groups does not represent an objective definition, but rather a way to better understand the meaning of plurality. At the same time modern technologies modify perceptive and cognitive transformation. This research shows that on-line groups develop objective dynamics in face-to-face groups; it evaluates the quality of the University student services and studies the dynamics of the ...

We describe an application used to share context and build common ground between nearby users. Our application runs on mobile devices and allows users securely to exchange the contents of their address books. This exchange reveals only which entries are common to the two users. We explore the use of our application using both Bluetooth and NFC as an underlying technology. Finally, we present th...
