Childhood and advances in human tool use

Human life history incorporates childhood, a lengthy post-weaning period of dependency. This species-specific period provides an opportunity for extensive learning and for sophisticated cultural behaviors to develop, including crucial tool use skills. Although I agree that no individual cognitive trait singularly differentiates humans from other animals, I suggest here that without childhood, the traits that are key to human tool use would not emerge.     

Fourteen‐Month‐Olds' Imitation of Differently Aged Models

Studies comparing adult and peer imitation are rare and have to date provided mixed results. The aim of the present study was to investigate 14‐month‐olds' imitation of different actions (novel versus familiar) performed by televised models of different age groups (peers, older children or adults). In two experiments, we investigated infants' imitative performance when observing a novel action (Experiment 1) and familiar actions (Experiment 2). The results showed that the likelihood of imitating a novel action increased as the age of the model increased. The opposite was true for familiar actions where infants imitated the peer more frequently than either the older child or the adult model. These findings are discussed in relation to infants' ability to take into account a model's characteristics such as age when imitating actions. Copyright © 2011 John Wiley & Sons, Ltd.

Electrophysiological evidence for greater attention to threat when cognitive control resources are depleted

In this study, we investigated the time course of attentional bias for threat-related (angry) facial expressions under conditions of high versus low cognitive (working memory) load. Event-related potential (ERP) and reaction time (RT) data were recorded while participants viewed pairs of faces (angry paired with neutral face) displayed for 500 ms and followed by a probe. Participants were required to respond to the probe while performing a concurrent task of holding in working memory a sequence of digits that were either in the same order (low memory load) or in a random mixed order (high memory load). The ERP results revealed that higher working memory load resulted in enhanced lateralized neural responses to threatening relative to neutral faces, consistent with greater initial orienting of attention to threatening faces (early N2pc: 180–252 ms) and enhanced maintenance of processing representations of threat (late N2pc, 252–320 ms; SPCN, 320–500 ms). The ERP indices showed significant positive relationships with each other, and also with the behavioral index of attentional bias to threat (reflected by faster RTs to probes replacing angry than neutral faces at 500 ms), although the latter index was not significantly influenced by memory load. Overall, the findings indicate that depletion of cognitive control resources, using a working memory manipulation, increases the capacity of task-irrelevant threat cues to capture and hold attention.     

Opening the black box: Presenting a model for evaluating organizational-level interventions

Organizational-level occupational health interventions are often recommended when improvements in working conditions, employee health, and well-being are sought within organizations. Research has revealed that these interventions result in inconsistent effects despite being based on theoretical frameworks. This inconsistency indicates that intervention studies need to be designed to examine directly how and why such interventions bring about change and why they sometimes fail. We argue that intervention studies should include a process evaluation that includes a close examination of the psychological and organizational mechanisms that hinder and facilitate desired intervention outcomes. By drawing on existing intervention literature we present an evidence-based model containing three levels of elements that appear to be crucial in process evaluation. We describe how this model may be applied and developed in future research to identify better the mechanisms that link intervention processes to intervention outcomes.     

Quaker ideology,colonialism and American Indian education

William Penn, the Quaker who founded Pennsylvania, set out to found a ‘Holy Experiment’ based on Quaker ideals. While he regarded the Native American Indians whose land he purchased as spiritual equals, he still expected them to convert to Christianity and live under British law. Later, Quakers continued to follow this goal, eventually becoming leaders, under President Grant, in the residential school system for Native American Indian children. They supported assimilation, contributing to the destruction of native culture and society, in contradiction to their principles of equality and integrity. This paper explores the process by which Quakers came to feel it necessary to pursue such measures in spite of their egalitarian beliefs.     

Toward a liberal socialist cosmopolitan nationalism

I explicate and defend a form of liberal socialist nationalism. It is also a nationalism which is cosmopolitan. Explication and explanation are crucially in order here, for it is not unreasonable to believe that ‘cosmopolitan nationalism’ and ‘liberal socialist nationalism’ and even ‘liberal nationalism’ are oxymoronic. Against that I argue that there is a straightforward understanding of these concepts and their relations to each other that does not have inconsistencies or even paradoxes. Liberal socialism properly understood goes well with cosmopolitanism (both moral and institutional), and there are plausible and attractive forms of both liberalism and socialism that go together. Moreover, the only candidate for a nationalism that would survive careful reflective inquiry is a liberal nationalism: a nationalism which is neither ethnic nor civic. It is widely believed, however, that even a liberal nationalism is incompatible with cosmopolitanism. I contend in a series of arguments that in contexts where nationalism is rightly on the agenda the form that it should take is that of a liberal nationalism, and it is further argued that to be viable, nationalism requires cosmopolitanism.     

An un‐Rortyan defence of Rorty's pragmatism

An identification is made of the core metaphilosophical, philosophical, and intellectual history theses in Richard Rorty's pragmatism. Their rationale is displayed and it is argued that his metaphilosophical theses are very much dependent on certain of his non‐metaphilosophical philosophical theses, most centrally his anti‐representationalism. Questions emerge about the status and justification of these theses. Rorty, in his programmatic pronouncements, resists providing a vindication of them. Seeking to avoid what has been called performative contradictions, he regards it as sufficient to provide the best narrative going of what is to be said here. It is argued that a more straightforward defence can be provided that does not depart from his holism or his historicism with its setting aside of claims of necessity.
