Cortical memory mechanisms and language origins

We have previously proposed that cortical auditory-vocal networks of the monkey brain can be partly homologized with language networks that participate in the phonological loop. In this paper, we suggest that other linguistic phenomena like semantic and syntactic processing also rely on the activation of transient memory networks, which can be compared to active memory networks in the primate. Consequently, short-term cortical memory ensembles that participate in language processing can be phylogenetically tracked to more simple networks present in the primate brain, which became increasingly complex in hominid evolution. This perspective is discussed in the context of two current interpretations of language origins, the "mirror-system hypothesis" and generativist grammar.     

The Effect of Perspective‐Giving on Postconflict Reconciliation. An Experimental Approach

Discussion groups are a promising tool for bridging the divide between former conflict antagonists. However, such groups do not always produce the desired outcome of improved attitudes, even when they meet the conditions generally seen as favoring positive interaction. In this article, we examine specific discussion protocols that mitigate polarization risks while fostering reconciliation. Using a randomized, controlled design, we formed a pool of 429 ex‐combatants and members of conflict‐affected communities in Colombia. Participants were asked to join heterogeneous groups and discuss their proposals for the future of Colombia. Overall, community members improved their attitudes towards ex‐combatants significantly, while ex‐combatants’ attitudes toward community members do not tend to polarize. Those participants who were randomly assigned to a perspective‐giving treatment protocol (where they were asked to refer to their personal experience and perspective) consistently improved their intergroup attitudes towards ex‐combatants, and by a proportionally higher percentage than those taking part under argumentation and no‐treatment control conditions.     

The Exemption that Confirms the Rule: Reflections on Proceduralism and the UK Hybrid Embryos Controversy

This paper provides an interpretation of the licensing provisions envisaged under the Human Fertilisation and Embryology Act 1990 as a model for a rule and exemption-based procedural strategy for the adjudication of potential ethical controversies, and it offers an account of the liberal-democratic legitimacy of the procedure’s outcomes as well as of the legal procedure itself. Drawing on a novel articulation of the distinction between exceptions and exemptions, the paper argues that such a rule and exemption mechanism, while not devoid of attractions, is not immune from the criticisms often levied against procedural approaches to the management of pluralism: it either has to fall back on substantive justification in ways that are not helpful when trying to arbitrate a moral controversy, or it appears justificatorily groundless.     

Legitimacy, Democracy and Public Justification: Rawls’ Political Liberalism Versus Gaus’ Justificatory Liberalism

Public justification-based accounts of liberal legitimacy rely on the idea that a polity’s basic structure should, in some sense, be acceptable to its citizens. In this paper I discuss the prospects of that approach through the lens of Gerald Gaus’ critique of John Rawls’ paradigmatic account of democratic public justification. I argue that Gaus does succeed in pointing out some significant problems for Rawls’ political liberalism; yet his alternative, justificatory liberalism, is not voluntaristic enough to satisfy the desiderata of a genuinely democratic theory of public justification. So I contend that—pace Gaus, but also Rawls—rather than simply amending political liberalism, the claims of justificatory liberalism bring out fatal tensions between the desiderata of any theory of liberal-democratic legitimacy through public justification.     

Motor imagery effectiveness for mirror reversed movements

Physical practice is known to enhance motor adaptation skills, which refer to the individual ability to compensate for environmental changes. So far, it is still unknown whether a similar effect can be observed following motor imagery (MI). Thirty-nine participants were tested during a joystick tracking task under both normal and mirror conditions (i.e., the inductive direction of the joystick was reversed), before and after a physical practice or MI training phase. Eye movements and electromyographic activity were recorded during MI. Motor performance was also evaluated after a 6 h interval during daytime. As compared to the control group, the results revealed that both MI and physical practice improved motor performance in the mirror condition, during the post-training test. Furthermore, the time to complete the task was further reduced after 6 hours, both in the normal and mirror conditions. These results demonstrate the effectiveness of MI for learning mirror-reversed movements, and for the consolidation process that follows motor adaptation.
