Interest in the comparative study of mirror self-recognition persists because of the implications for self-awareness and the possibility of a cognitive divide among primates. Evidence from many studies carried out over 40 years shows that humans and great apes are distinguished from other nonhuman primates by their capacity for self-recognition. We review some recent developments in the field, ...

Claims based on observational studies that a treatment has certain effects are often met with counterclaims asserting that the treatment is entirely without effect, that all associations with treatment are produced by biased treatment assignment. Some counterclaims undermine themselves in the following specific sense: presuming the counterclaim to be true may strengthen the support that the ori...

By distinguishing groups of dopamine neurons that differ in their projection patterns and intrinsic properties, Lammel and colleagues report in this issue of Neuron that mesocorticolimbic dopamine neurons of the ventral tegmental area (VTA) form a distinct subclass of dopamine cells.

Some fluents (for instance, time) change even after events that are not assumed to affect them (such as the action wait). We propose a formal-ization of the "commonsense law of inertia" in the situation calculus that allows us to describe such fluents. 1 Introduction The frame problem in Artificial Intelligence is the problem of specifying formally "what doesn't change when an event occurs" in ...

Abstract Questions on the theory of cognition formed one focal points in dispute between orthodox Russian Marxists and Aleksandr Bogdanov his followers. was an adherent Mach’s theory, which abandoned Kant’s concept “things-in-themselves” ( Ding sich ) outside cognizing subject. According to Mach Bogdanov, there is no need duplicate human experience appearances given senses things behind these a...

Collaboration requires coordination, and we coordinate by anticipating our teammates’ future actions and adapting to their plan. In some cases, our teammates’ actions early on can give us a clear idea of what the remainder of their plan is, i.e. what action sequence we should expect. In others, they might leave us less confident, or even lead us to the wrong conclusion. Our goal is for robot ac...
