Only a small handful of perceptual experiments have directly looked at how listeners identify and categorize where talkers are from based on actual speech samples. Our fi...

Furthermore, we have recently demonstrated that in the extrapersonal space, our categorization also depends on the movement potential of other agents. When we have to categorize the space as "Near" or "Far" between a refe...

The aim of this study was to investigate whether chimpanzees (n = 5), our closest living relatives, detect and categorize faces on the basis of first-order information, and whether this sensitiv...
