The explainability of robotic systems depends on people’s ability to reliably attribute perceptual beliefs robots, i.e., what robots know (or believe) about objects and events in the world based their perception. However, are not necessarily well understood by majority people interacting with them. In this article, we explain why is a significant, difficult, unique problem social robotics. inab...

Perceptual time is a critical aspect of how humans (and probably animals too) perceive the world. It underlies general intelligence, particularly where that general intelligence is about interacting with the world on an everyday basis. We discuss what is meant by the perceptual instant, and how this may be important for (artificial and real) general intelligence. Lastly, we briefly discuss how ...

The flourishing of studies on the neural correlates of decision-making calls for an appraisal of the relation between perceptual decisions and conscious perception. By exploiting the long integration time of noisy motion stimuli, and by forcing human observers to make difficult speeded decisions--sometimes a blind guess--about stimulus direction, we traced the temporal buildup of motion discrim...

Perceptual linearization has been advocated for medical image presentation, both for the faithful reproduction of images, and for standardizing the appearance across different display devices. At this time, few studies have attempted to evaluate the effectiveness of a post-processing perceptual linearization step. We have recently analyzed the methods for computing perceptual linearization rema...
