We survey a variety of experimental paradigms for studying animal abilities to count, to understand numerical information and to perform simple arithmetic operations. There is a huge body of evidence that different forms and elements of quantitative judgement and numerical competence are spread across a wide range of species, both vertebrate and invertebrate. Here we pay particular attention to...

This article aims to provide an inventory of the communicative gestures used by bonobos (Pan paniscus), based on observations of subadult bonobos and descriptions of gestural signals and similar behaviors in wild and captive bonobo groups. In addition, we focus on the underlying processes of social cognition, including learning mechanisms and flexibility of gesture use (such as adjustment to th...

non-verbal communication (nvc) plays a major role in various aspects of human life (andersen, 2004; cameron, 2001; johnstone, 2008). children learning their first language come to realize non-verbal communication as their socialization process takes place (fletcher & german, 1990; ingram, 1996; owens, 2001). however, most efl learners may have little exposure to these non-verbal aspects of ...

In the framework of fully cooperative multi-agent systems, independent (non-communicative) agents that learn by reinforcement must overcome several difficulties to manage to coordinate. This paper identifies several challenges responsible for the non-coordination of independent agents: Pareto-selection, nonstationarity, stochasticity, alter-exploration and shadowed equilibria. A selection of mu...

From an investigation about the factors influencing the trilingual education in Chinese ethnic minority regions, the author find out that the minority students are incompetent in English learning. Inappropriate teaching strategies, learning materials as well as language policy hinder the development of teaching and learning progress in those areas, which still causes the minority students’ lack...
