Internal (neuronal) representations in the brain are modified by our experiences, and this phenomenon is not unique to sensory and motor systems. Here, we show that different impressions obtained through social interaction with a variety of agents uniquely modulate activity of dorsal and ventral pathways of the brain network that mediates human social(More)
In Arabidopsis, three genes (AHK2, AHK3 and AHK4/CRE1) encode histidine kinases (His-kinases), which serve as cytokinin receptors. To understand how the external cytokinin signal activates the His-kinase across the cell membrane, we exploited the power of microbial genetics to isolate several AHK4 mutants that function independently of cytokinin in both(More)
In the present study, we investigated whether a robot is able to deceive a human by producing a behavior against him/her prediction. A feeling of being deceived by a robot would be a strong indicator that the human treat the robot as an intentional entity. We conducted a psychological experiment in which a subject played Darumasan ga Koronda, a Japanese(More)
SUMMARY We describe attempts to have robots behave as embodied knowledge media that will permit knowledge to be communicated through embodied interactions in the real world. The key issue here is to give robots the ability to associate interactions with information content while interacting with a communication partner. Toward this end, we present two(More)
Although product recommendation virtual agents (PRVAs) are used in a large number of online shopping websites, the optimal types of agents in this context remain unclear. In the present study, we tested whether agent appearance affects people's buying motivations and analyzed the key factors in persuading people to buy products. The experimental results(More)
