Over the last few decades, comparative cognitive research has focused on the pinnacles of mental evolution, asking all-or-nothing questions such as which animals (if any) possess a theory of mind, culture, linguistic abilities, future planning, and so on. Research programs adopting this top-down perspective have often pitted one taxon against another, resulting in sharp dividing lines. Insight into the underlying mechanisms has lagged behind. A dramatic change in focus now seems to be under way, however, with increased appreciation that the basic building blocks of cognition might be shared across a wide range of species. We argue that this bottom-up perspective, which focuses on the constituent capacities underlying larger cognitive phenomena, is more in line with both neuroscience and evolutionary biology. Introduction A few decades ago, scientists focused on language -a typically human characteristic -to see how far apes could go with it. When attempts to teach apes speech failed, training moved to the gestural domain and performance exceeded expectations: symbolic communication seemed to be within the grasp of our close relatives The field of animal cognition rarely shies away from advanced faculties, leading to regular conflict regarding the human-animal divide. But what if we were to replace our obsession with complex cognition with an exploration of basic processes? Instead of asking which species can do X, the question would become how does X actually work? What are the necessary ingredients of X and how did these evolve? We pursue this bottom-up perspective in this article by reviewing recent research on future planning, imitation and altruistic behavior to demonstrate how complex capacities can often be broken down into components that humans share not just with the apes, but also with a host of other species. We argue that to document and understand these components at the neural level should be our highest priority. This approach, which has been gaining ground in the last few years, will move the field of comparative cognition towards an understanding of capacities in terms of underlying mechanisms and the

Abstract Mathematics education is complicated by issues related to cohesion and connectivity within the subject, and in its relationships to other subjects, and these issues are reflected in studies of exceptionality in mathematics. Some recent studies have argued that consideration of the connectivity of mathematics as a subject may benefit from an emphasis on broad approaches to studies of mathematics within generalist models of cognition, including approaches based in modern scientific research and recent studies of networks and complexity. This paper explores the contribution that studies in exceptionality have made in resolving the issue of connectivity in mathematics, and examines efforts being made for a more unified conceptualisation of the subject through broad approaches. A description of learning and memory, based in a novel information framework, is explored as a basis for a generalist cognitive model which may accommodate mathematics concepts within a broader educational context. This model may provide insights into the examination of the connectivity of mathematics as well as methods for teaching the subject in modern educational institutions.

================================================================= Abstract An attempt is made here to approach the origin and evolution of human language from the foundational perspective of the faculty of language as a species specific attribute, found nowhere else in the animal kingdom. The rebirth of cognitive psychology started with Noam Chomsky as a major development in attempting a scientific basis of the understanding of language with a major empirical basis in neurobiology and neuroethology. While the study of language still remains a challenging area for philosophical and methodological debate, it enlightens many new areas of cognitive psychology and sets many new neuroscientific agenda for future research. The biolinguistic, biosemiotic and neurobiological perspective focuses the origin of language problem as a working programme to find fruitful answers to many questions in neurology and attempts solutions to correct many language disorders in clinical practice.

One longstanding impediment to progress in understanding the neural basis of language is the development of model systems that retain language-relevant cognitive behaviors yet permit invasive cellular neuroscience methods. Recent experiments in songbirds suggest that this group may be developed into a powerful animal model, particularly for components of grammatical processing. It remains unknown, however, what a neuroscience of language perception may look like when instantiated at the cellular or network level. Here we deconstruct language perception into a minimal set of cognitive processes necessary to support grammatical processing. We then review the current state of our understanding about the neural mechanisms of these requisite cognitive processes in songbirds. We note where current knowledge is lacking, and suggest how these mechanisms may ultimately combine to support an emergent mechanism capable of processing grammatical structures of differing complexity.

In this paper we propose a way in which cognitive neuroscience could provide new insights on three aspects of social cognition: intersubjectivity, the human self, and language. We emphasize the crucial role of the body, conceived as the con-stitutive source of pre-reflective consciousness of the self and of the other. We provide a critical view of contemporary social cognitive neuroscience, arguing that the brain level of description is a necessary but not sufficient condition for study-ing intersubjectivity, the human self, and language; which are only properly vis-ible if coupled with a full appreciation of their intertwined relationship with the body. We introduce mirror mechanisms and embodied simulation and discuss their relevance to a new account of intersubjectivity and the human self. In this context, we focus on a specifically human modality of intersubjectivity: language. Aspects of social cognition related to language are discussed in terms of embodiment, while emphasizing the progress and limitations of this approach. We argue that a key aspect of human language consists in its decoupling from its usual denotative role, hence manifesting its power of abstraction. We discuss these features of hu-
