Language is a cognitively demanding human trait, but it is also a fundamentally cooperative enterprise that rests on the motivation to share information. Great apes possess many of the cognitive prerequisites for language, but largely lack the motivation to share information. Callitrichids (including marmosets and tamarins) are highly vocal monkeys that are more distantly related to humans than great apes are, but like humans, they are cooperative breeders and all group members help raising offspring. Among primates, this rearing system is (...) correlated with proactive prosociality, which can be expressed as motivation to share information. We therefore propose that the unique coincidence of these two components in humans set the stage for language evolution: The cognitive component inherited from our great ape-like ancestors, and the motivational one added convergently as a result of cooperative breeding. We evaluate this scenario based on a review of callitrichd vocal communication and show that furthermore, they possess many of the mechanistic elements emphasized by the mirror system hypothesis of language evolution. We end by highlighting how more systematic phylogenetic comparisons will enable us to further promote our understanding of the role of cooperative breeding during language evolution. (shrink)

ABSTRACTGeneralisation in learning means that learning with one particular stimulus influences responding to other novel stimuli. Such generalisation effects have largely been overlooked within res...

Infants initiate joint attentional exchanges by pointing relevant referents out to addressees. Over the second year of life, the functional meaning of the pointing gesture develops from declarative (sharing a referent) to informational (giving some information that is new to the addressee). This chapter analyzes this transition in the development of pointing based on experimental evidence about its production contexts and, in particular, of variables concerning the visibility of referents for infant and addressee. Further evidence is reported concerning the association (...) of pointing with vocalizations and visual checking towards the addressee in different temporal sequencing. It is argued that shared attention initiated by pointing plays a pivotal role in the intersection between social cognition and language development. (shrink)

This study investigated person perception in respect of variables associated with affect in music following motor synchronization to music. Participants were tested in a task involving stepping with a researcher to the beat of slow or fast music in major or minor mode, following which measures concerning the synchronised partner were collected. Significant effects were found only for the ‘likeability’ measure, modulated by gender, suggesting that variables associated with affect perception in music, such as mode and tempo appear relevant for (...) person perception in a synchronization task in ways that differ for men and women. The results of this ‘proof of concept’ study indicate the need for further research on the effect of motor synchronization based on ecologically valid musical interaction tasks. (shrink)

Conception has a prominent role to play in Thomas Reid’s philosophy of mind, as is apparent from his Essays on the Intellectual Powers of Man (EIP henceforth). The present investigation concerns Reid’s explanation of how objects (be they real or nonexistent) are conceived. According to him, conception functions in two different ways: it is either an ingredient in another act of thinking, such as perception or memory, or it is exercised by itself, sometimes about objects that do not (and will (...) never) exist. Fictional objects can be remembered, but to do so the mind needs an initial, independent grip on them, which can only be achieved by an exercise of “bare conception”. (shrink)

Cet article propose une voie d’issue pour sortir de l’antinomie dans laquelle se trouvent souvent les défenseurs de la liberté académique, celle du libéralisme ou du « républicanisme » d’État, et donc de la penser autrement que comme un cas particulier de la liberté d’expression tout en évitant d’en faire le privilège d’un corps social (les universitaires) dont le peuple serait exclu. La philosophie de Spinoza nous permet de redéfinir la liberté académique comme une modalité de la liberté de penser, (...) et plus précisément de la liberté de philosopher, et nous offre un cadre utile pour comprendre le rôle des universités publiques dans le développement de la puissance de penser des masses citoyennes et leur centralité dans la conservation d’un État démocratique.

It is commonly believed that people become selfish and turn to looting, price gouging, and other immoral behaviour in emergencies. This has been the basis for an argument justifying extraordinary measures in emergencies. It states that if emergencies are not curtailed, breakdown of moral norms threaten (‘the moral black hole’). Using the example of natural disasters, we argue that the validity of this argument in non-antagonistic situations, i.e. situations other than war and armed conflict, is highly questionable. Available evidence suggests (...) that people in such emergencies typically do not display panic reactions or exaggerated selfishness, and that phenomena such as looting and price gouging are rare. Furthermore, a version of the moral-black-hole argument based on the mere possibility of a moral black hole occurring runs into problems similar to those of Pascal’s Wager. We conclude that we should be wary against applying the moral-black-hole argument to non-antagonistic cases. (shrink)

Occupational health remains neglected in developing countries because of competing social, economic and political challenges. Ethical issues in the workplace related to the hazards and risks of becoming infected by Leishmania (Leishmania) mexicana, through the bite of naturally infected sand flies, is another area of concern that has been neglected as well. We report here the results of reviewing two entomological field studies carried out in our research center from 2003 to 2006. Eight students from our School of Biology were (...) invited to catch sand flies. A total of six of the eight (75%) developed a typical clinical picture of Localized Cutaneous Leishmaniasis (LCL) caused by L. (L.) mexicana. In this article we identify the ethical issues related to these kinds of studies and propose some guidelines for conducting them. (shrink)

This paper explores the evolution of the Universal Declaration on Bioethics and Human Rights , which was adopted by the United Nations Educational, Scientific and Cultural Organization in 2005. While the draft UDBHR generated controversy among bioethicists, the process through which it evolved excluded mainstream bioethicists. The absence of peer review affects the declaration’s content and significance. This paper critically analyses its content, commenting on the failure to acknowledge socioeconomic and other factors that impede its implementation. The UDBHR outlines ideal (...) standards but fails to provide guidance that can be readily applied in different settings. It strives for universality but does not contribute to understanding of universal or global bioethics.The Universal Declaration on Bioethics and Human Rights was developed through multinational consultation over several years. It was officially adopted by the United Nations Educational, Scientific and Cultural Organization in October 2005.1 This paper explores the process of drafting the UDBHR, critically analyses its content and considers its status in the context of global bioethics. It comments on the UDBHR’s failure to acknowledge or respond to socioeconomic and other factors that impede attempts to implement it. The paper concludes that the process of drafting the declaration excluded a necessary group of stakeholders and that the UDBHR therefore fails to provide the guidance it aims to offer.Identifying a need to develop universally applicable ethical guidelines within a context of cultural pluralism, Unesco began developing a draft Declaration on Universal Norms on Bioethics. A near final draft was posted on Unesco’s website in February 2005 and replaced in June 2005 with the version subsequently adopted as the UDBHR. Stakeholder consultation on the draft involved hundreds of people in many diverse nations. These were seemingly limited to consultations with Unesco affiliates, however, and public comment was not solicited. …. (shrink)

That memory reconsolidation is the process underlying decisive, lasting therapeutic change has long been our proposal, and the recognition of its critical role by Lane et al. is a welcome development. However, in our view their account has significant errors due to neglect of research findings and neglect of previous work on the clinical application of those findings.
