No full textNumerical cognition in birds
No full textAvian species are one of the most diverse and adaptable groups of animals: there are far more species of birds than of mammals, and they occupy a broad range of habitats. Birds and mammals split from a common ancestor over 300 million years ago. Yet certain bird species can perform complex mental tasks, including numerical problems, at levels similar to — and in some cases surpassing — primates, including great apes. Birds thus offer a privileged perspective on the cognitive functions underlying numerical abilities and their evolution. Moreover, birds provide excellent models for studying the ontogenetic development and neural mechanisms underlying numerical computations. In this Review, we provide a comprehensive picture of the contribution of avian studies to understanding numerical cognition, including behavioural laboratory studies, field studies and neurobiological investigations. We also critically examine the methodologies, interpretations and limitations of selected key studies. By synthesizing current knowledge and situating it within the broader field of cognitive research, we highlight the importance of a comparative perspective in understanding the role of evolutionary convergence in the emergence of cognitive functions
Young children's understanding of the context-relativity of normative rules in conventional games
No full textWe investigated young children's awareness of the context-relative rule structure of simple games. Two contexts were established in the form of spatial locations. Familiar objects were used in their conventional way at location 1, but acquired specific functions in a rule game at location 2. A third party then performed the conventional act at either of the two locations, constituting a mistake at location 2 (experimental condition), but appropriate at location 1 (control condition). Three-year-olds (but not 2-year-olds) systematically distinguished the two conditions, spontaneously intervening with normative protest against the third party act in the experimental, but not in the control condition. Young children thus understand context-specific rules even when the context marking is non-linguistic. These results are discussed in the broader context of the development of social cognition and cultural learning

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
