When parallel processing in visual word recognition is not enough: new evidence from naming

Low-frequency irregular words are named more slowly and are more error prone than low-frequency regular words (the regularity effect). Rastle and Coltheart (1999) reported that this irregularity cost is modulated by the serial position of the irregular grapheme-phoneme correspondence, such that words with early irregularities exhibit a larger cost than words with late ones. They argued that these data implicate rule-based serial processing, and they also reported a successful simulation with a model that has a rule-based serial component—the DRC model of reading aloud (Coltheart, Rastle, Perry, Langdon, & Ziegler, 2001). However, Zorzi (2000) also simulated these data with a model that operates solely in parallel. Furthermore, Kwantes and Mewhort (1999) simulated these data with a serial processing model that has no rules for converting orthography to phonology. The human data reported by Rastle and Coltheart therefore neither require a serial processing account, nor successfully discriminate among a number of computational models of reading aloud. New data are presented wherein an interaction between the effects of regularity and serial position of irregularity is again reported for human readers. The DRC model simulated this interaction; no other implemented computational model does so. The present results are thus consistent with rule-based serial processing in reading aloud.     

Individual Differences in Attachment and Reproductive Strategies: Commentary on Buss & Greiling

Buss and Greiling cite individual differences in attachment as a principal illustration of adaptive individual differences. This particular example, however, is a highly controversial one: Many if not most relationship researchers assume (implicitly or explicitly) that insecure attachment patterns reflect some kind of malfunction of the attachment system in modern environments rather than evolved facultative strategies. I therefore review some of the arguments and evidence on both sides of this issue, along with the closely related topics of mating/reproductive strategies and parental investment. In the end I support the Buss-Greiling position, but for reasons not discussed in their article.     

Maternal parenting as a mediator of the relationship between intimate partner violence and effortful control

The current study examined the relationship between intimate partner violence (IPV), maternal parenting behaviors, and child effortful control in a diverse sample of 705 families living in predominantly low-income, rural communities. Using structural equation modeling, the authors simultaneously tested whether observed sensitive parenting and/or harsh-intrusive parenting over the toddler years mediated the relationship between early IPV and later effortful control. Results suggest that parenting behaviors fully mediate this relationship. Although higher levels of IPV were associated with both higher levels of harsh-intrusive parenting and lower levels of sensitive supportive parenting, only sensitive supportive parenting was associated with later effortful control when both parenting indices were considered in the same model.     

Bridging a yawning chasm: EEG investigations into the debate concerning the role of the human mirror neuron system in contagious yawning

Ongoing debate in the literature concerns whether there is a link between contagious yawning and the human mirror neuron system (hMNS). One way of examining this issue is with the use of the electroencephalogram (EEG) to measure changes in mu activation during the observation of yawns. Mu oscillations are seen in the alpha bandwidth of the EEG (8–12 Hz) over sensorimotor areas. Previous work has shown that mu suppression is a useful index of hMNS activation and is sensitive to individual differences in empathy. In two experiments, we presented participants with videos of either people yawning or control stimuli. We found greater mu suppression for yawns than for controls over right motor and premotor areas, particularly for those scoring higher on traits of empathy. In a third experiment, auditory recordings of yawns were compared against electronically scrambled versions of the same yawns. We observed greater mu suppression for yawns than for the controls over right lateral premotor areas. Again, these findings were driven by those scoring highly on empathy. The results from these experiments support the notion that the hMNS is involved in contagious yawning, emphasise the link between contagious yawning and empathy, and stress the importance of good control stimuli.     

Acquisition of social referencing via discrimination training in infants

This experiment investigated social referencing as a form of discriminative learning in which maternal facial expressions signaled the consequences of the infant's behavior in an ambiguous context. Eleven 4- and 5-month-old infants and their mothers participated in a discrimination-training procedure using an ABAB design. Different consequences followed infants' reaching toward an unfamiliar object depending on the particular maternal facial expression. During the training phases, a joyful facial expression signaled positive reinforcement for the infant reaching for an ambiguous object, whereas a fearful expression signaled aversive stimulation for the same response. Baseline and extinction conditions were implemented as controls. Mothers' expressions acquired control over infants' approach behavior for all participants. All participants ceased to show discriminated responding during the extinction phase. The results suggest that 4- and 5-month-old infants can learn social referencing via discrimination training.     

‘Too black or not black enough’: Social identity complexity in the political rhetoric of Barack Obama

The election of the first African‐American President of the United States, Barack Obama, has been widely recognised as an extraordinary milestone in the history of the United States and indeed the world. With the use of a discursive psychological approach combined with central theoretical principles derived from social identity and self‐categorisation theories, this paper analyses a corpus of speeches Obama delivered during his candidacy for president to examine how he attended to and managed his social identity in his political discourse. Building on a social identity model of leadership, we examine specifically how Obama mobilises political support and social identification by building an identity for himself as a prototypical representative of the American people, notwithstanding the protracted public debate within both the White and Black American communities that had questioned and contested Obama's identity. Moreover, we demonstrate how Obama managed the dilemmas around his identity by actively crafting an in‐group identity that was oriented to an increasingly socially diverse America—a diversity that he himself exemplified and embodied as a leader. As an ‘entrepreneur’ of identity, Obama's rhetorical project was to position himself as an exceptional leader, whose very difference was represented as ‘living proof’ of the widely shared collective values that constitute the ‘American Dream’. Drawing on social identity complexity theory, we suggest that by providing more inclusive and complex categories of civic and national identity, Obama's presidency has the potential to radically transform what it means to be a prototypical in‐group member in America.

Using a Training-of-Trainers Approach and Proactive Technical Assistance to Bring Evidence Based Programs to Scale: An Operationalization of the Interactive Systems Framework’s Support System

Bringing evidence based programs to scale was a major initial impetus for the development of the Interactive Systems Framework for Dissemination and Implementation (ISF). The ISF demonstrates the importance of the Support System in facilitating the uptake of innovations in the community (the Delivery System). Two strategies that members of the Support System commonly use are training‐of‐trainers (TOT) models and technical assistance (TA). In this article, we focus on the role of the Support System in bringing evidence‐based programs (EBPs) to scale in the Delivery System using a case example, with special attention on two strategies employed by Support Systems—training‐of‐trainers (TOT) and proactive technical assistance. We then report on findings from a case example from the Promoting Science Based Approaches to Teen Pregnancy Prevention project that furthers our conceptualization of these strategies and the evidence base for them. We also report on the limitations in the literature regarding research on TOTs and proactive TA and provide suggestions for future research on TOTs and proactive TA that will enhance the science and practice of support in the ISF.

An integrated approach to delivering exposure-based treatment for symptoms of PTSD and depression in OIF/OEF veterans: preliminary findings

Combat-exposed military personnel from the wars in Iraq and Afghanistan report high rates of PTSD and associated psychiatric problems. A formidable body of research supports exposure therapy as a front-line intervention for PTSD; however, relative to studies of civilians, fewer investigations have evaluated the effectiveness of exposure therapy using military samples. Specifically, barriers to care (e.g., stigma associated with receiving mental health services ) may compromise utilization of evidence-based psychotherapy. As such, researchers have argued that veterans with PTSD may require an integrated and innovative approach to the delivery of exposure techniques. This paper presents the rationale for and preliminary data from an ongoing clinical trial that compares the home-based telehealth (HBT) application of a brief, behavioral treatment (Behavioral Activation and Therapeutic Exposure; BA-TE) for veterans with PTSD to the standard, in-person application of the same treatment. Forty OIF/OEF veterans with PTSD and MDD were consented, enrolled, and randomized to condition (BA-TE in-person, or BA-TE HBT) and symptoms of anxiety and depression were assessed at pre- and posttreatment. Participants in both conditions experienced reductions in depression, anxiety, and PTSD symptoms between pre- and posttreatment, suggesting that HBT application of an integrated PTSD treatment may be feasible and effective.     

Rudd's Apology to the Stolen Generations: Challenging Self‐Sufficient Arguments in “Race” Discourse

While the public debate on whether to apologise to the Stolen Generations ended on 13 February, 2008, public opinion was still divided, reflected particularly in the arguments against apologising that were common in political and public discourse. We examine the ways in which differing arguments can be flexibly deployed and combined within a political context to not just resist, but also to support, an act of reparation for historical injustice. In particular, we consider how Rudd makes use of specific rhetorically self‐sufficient arguments to justify offering the apology; precisely the same arguments that had previously been used by political leaders and members of the public to oppose the apology. It is the use of such arguments in combination with each other and additional common tropes drawn from egalitarian and liberal discourse that allow for the building of a rhetorically powerful case for offering the apology. Rather than the traditional focus of such research on the ways in which racism is accomplished in talk, we suggest that Rudd's apology to the Stolen Generations can be seen as a practical tool‐kit for building an “anti‐racist” rhetoric in the context of Indigenous and non‐Indigenous relations in Australia.
