Working memory is the system responsible for maintaining and manipulating information, in the face of ongoing distraction. In turn, WM span is perceived to be an individual-differences construct reflecting the limited capacity of this system. Recently, however, there has been some evidence to suggest that WM capacity can increase through training, raising the possibility that training can functionally alter the neural structures supporting WM. To address the hypothesis that the neural substrates underlying WM are targeted by training, we conducted a (...) meta-analysis of functional magnetic resonance imaging studies of WM training using Activation Likelihood Estimation. Our results demonstrate that WM training is associated exclusively with decreases in blood oxygenation level-dependent responses in clusters within the fronto-parietal system that underlie WM, including the bilateral inferior parietal lobule, middle and superior frontal gyri, and medial frontal gyrus bordering on the cingulate gyrus. We discuss the various psychological and physiological mechanisms that could be responsible for the observed reductions in the BOLD signal in relation to WM training, and consider their implications for the construct of WM span as a limited resource.

This book explores the dynamic relationship between myth and philosophy in the Presocratics, the Sophists, and in Plato - a relationship which is found to be more extensive and programmatic than has been recognized. The story of philosophy's relationship with myth is that of its relationship with literary and social convention. The intellectuals studied here wanted to reformulate popular ideas about cultural authority and they achieved this goal by manipulating myth. Their self-conscious use of myth creates a self-reflective philosophic sensibility (...) and draws attention to problems inherent in different modes of linguistic representation. Much of the reception of Greek philosophy stigmatizes myth as 'irrational'. Such an approach ignores the important role played by myth in Greek philosophy, not just as a foil but as a mode of philosophical thought. The case studies in this book reveal myth deployed as a result of methodological reflection, and as a manifestation of philosophical concerns. (shrink)

Marketers use autobiographical advertising as a means to create nostalgia for their products. This research explores whether such referencing can cause people to believe that they had experiences as children that are mentioned in the ads. In Experiment 1, participants viewed an ad for Disney that suggested that they shook hands with Mickey Mouse as a child. Relative to controls, the ad increased their confidence that they personally had shaken hands with Mickey as a child at a Disney resort. The (...) increased confidence could be due to a revival of a true memory or the creation of a new, false one. In Experiment 2, participants viewed an ad for Disney that suggested that they shook hands with an impossible character (e.g., Bugs Bunny). Again, relative to controls, the ad increased confidence that they personally had shaken hands with the impossible character as a child at a Disney resort. The increased confidence is consistent with the notion that autobiographical referencing can lead to the creation of false or distorted memory. ᭧ 2002 John Wiley & Sons, Inc. (shrink)

Although there is evidence parent–child attachment security is associated with trait-like emotion indices, trait perspectives do not fully capture children's responses to context, an important emotion regulation component. This paper evaluates whether attachment is associated with two dynamic emotion indicators: emotion reactivity and emotion recovery. We review conceptual and empirical connections, describe the dynamic emotion perspective, discuss hypotheses, and review evidence. Our review (15 studies) shows that secure attachment was more consistently related to recovery than reactivity, avoidant attachment was related (...) to low emotion reactivity and recovery, ambivalent attachment was associated with greater emotion reactivity, and disorganized attachment was related to high reactivity and recovery difficulties. We close by comparing trait-like and dynamic emotion conclusions then propose future research directions. (shrink)

In the 1970s, two events in particular, the William Tyndale School and James Callaghan's Ruskin speech, generated extensive media coverage and political activity and became 'watersheds' along the path to political and educational reform. This has shaped the system of school and governments in the 1990s. This book revisits Tyndale and Ruskin and examines their legacy. Drawing on contemporary accounts of a number of key individuals who were involved in those watershed events, it recasts their stories in the light of (...) current changes in education. The book explores the extent to which both these events shifted assumptions about education and provided the rationale for policy changes. It argues that fundamental questions need to be asked about the nature of the reform agenda and in particular, the balance of power. It also places the reform agenda within an international context.

The target article proposes a model to explain the emergence of sex differences in attachment in middle childhood and their implications for reproductive strategies. While biological factors are prominent in the model, little is said about the social context of middle childhood and its contributions. There is also a need to clarify the fundamental nature of attachment in middle childhood.

This hypothesis proposes that increased extracellular glutamate in Amyotrophic Lateral Sclerosis (ALS) and cerebral ischemia, currently viewed as a trigger for excitotoxicity, is actually beneficial as it stimulates the utilization of glutamate as metabolic fuel. Renewed appreciation of glutamate oxidation by ischemic neurons has raised questions regarding the role of extracellular glutamate in ischemia. Is it detrimental, as suggested by excitotoxicity in early in vitro studies, or beneficial, as suggested by its oxidation in later in vivo studies? The answer may (...) depend on the activity of N‐methyl‐D‐aspartate (NMDA) glutamate receptors. Early in vitro procedures co‐activated NMDA receptors (NMDARs) containing 2A (GluN2A) and 2B (GluN2B) subunits, an event now believed to trigger excitotoxicity; however, during in vivo ischemia D‐serine and zinc molecules are released and these ensure only GluN2B receptors are stimulated. This not only prevents excitotoxicity but also initiates signaling cascades that allow ischemic neurons to import and oxidize glutamate. (shrink)

It is a commonplace of modern criticism that every text is to be located within a complex network of cultural practices and material. Students of the ancient world may sometimes feel at a disadvantage; we simply do not have as much information as we would like in order to contextualize thoroughly. This has been especially true in the study of Platonic dialogues. The meagre remains of the writings of the sophists against whom Plato measured himself and of the art to (...) which he refers entail that analysis of Plato is often confined to the structure of his philosophy. Of course, the requirements of Plato's arguments must always be assigned primary importance; the relative lack of information about Plato's cultural context has not prevented detailed exposition of his method and achievements. Occasionally, however, a kindly fate allows us to set a dialogue, or part of it, in its appropriate material and ideological context and to create an interface between literary, philosophical, and archaeological evidence. Such evidence may not alter our evaluation of Plato's arguments on the analytic level, but it can enrich our appreciation of his literary artistry and recapture for us some of the resonance that his work would have had for a contemporary audience.

There are clear associations between the overall quantity of input children are exposed to and their vocabulary acquisition. However, by uncovering specific features of the input that matter, we can better understand the mechanisms involved in vocabulary learning. We examine whether exposure to wh-questions, a challenging quality of the communicative input, is associated with toddlers' vocabulary and later verbal reasoning skills in a sample of low-income, African-American fathers and their 24-month-old children. Dyads were videotaped in free play sessions at home. (...) Videotapes were transcribed and reliably coded for sheer quantity of fathers' input as well as the number of wh-questions fathers produce. Children's productive vocabulary was measured at 24 months using the McArthur Bates Communicative Development Inventory MCDI, and children's verbal reasoning skills were measured 1 year later using the Bayley Scales of Infant Development. Results indicate that the overall quantity of father talk did not relate to children's vocabulary or reasoning skills. However, fathers' use of wh-questions related to both vocabulary and reasoning outcomes. Children's responses to wh-questions were more frequent and more syntactically complex, measured using the mean length of utterance, than their responses to other questions. Thus, posing wh-questions to 2-year-olds is a challenging type of input, which elicits a verbal response from the child that likely helps build vocabulary and foster verbal reasoning abilities.

Little is known about young children's ability to talk about absent members of their social network. We analyzed the speech of four children from 2 to 5 years. References to absent caregivers were relatively frequent, even when children were 2 years old. Such references were often generated spontaneously rather than being repetitions of a name produced by the child's interlocutor. Children's comments about absent family members occasionally expressed concern about contact with them but were predominantly neutral or reflective. By implication, (...) children can maintain a representation of the various members of their social network from an early age, despite separation. (shrink)

Attachment theory proposes that the activation of the attachment system enacts emotion regulation (ER) to maintain security or cope with insecurity. However, the effects of ER on attachment states and their bidirectional influences remain poorly understood. In this ecological momentary assessment study, we examined the dynamics between attachment and ER. We hypothesised that attachment states and ER influence each other through time. Specifically, we hypothesised bidirectional short-term cycles between state attachment security and reappraisal, state attachment anxiety and rumination, and state (...) attachment avoidance and suppression. We also tested how trait attachment is related to state attachment and ER. One hundred twenty-two participants (Mage = 26.4) completed the Experiences in Close Relationship–Revised and reported state attachment and ER seven times daily for seven days. The results were only partly consistent with our cycle hypotheses yet revealed a cycle between low state attachment security and rumination that was attenuated by reappraisal. Moreover, rumination and suppression predicted increased insecure states, and reappraisal predicted increased secure and insecure states. Finally, trait attachment showed associations with state attachment and ER. Our study suggests regulatory dynamics between attachment and ER and opens important questions about their functional relationship in maintaining attachment-related behavioural patterns and emotional well-being.

© JNCCN-Journal of the National Comprehensive Cancer Network.Background: Next-generation tumor sequencing panels, which include multiple established and novel targets across cancers, are emerging in oncology practice, but lack formal positive coverage by US payers. Lack of coverage may impact access and adoption. This study identified challenges of NGTS coverage by private payers.Methods: We conducted semi-structured interviews with 14 NGTS experts on potential NGTS benefits, and with 10 major payers, representing more than 125,000,000 enrollees, on NGTS coverage considerations. We used the (...) framework approach of qualitative research for study design and thematic analyses and simple frequencies to further describe findings.Results: All interviewed payers see potential NGTS benefits, but all noted challenges to formal coverage: 80% state that inherent features of NGTS do not fit the medical necessity definition required for coverage, 70% view NGTS as a bundle of targets versus comprehensive tumor characterization and may evaluate each target individually, and 70% express skepticism regarding new evidence methods proposed for NGTS. Fifty percent of payers expressed sufficient concerns about NGTS adoption and implementation that will preclude their ability to issue positive coverage policies.Conclusions: Payers perceive that NGTS holds significant promise but, in its current form, poses disruptive challenges to coverage policy frameworks. Proactive multidisciplinary efforts to define the direction for NGTS development, evidence generation, and incorporation into coverage policy are necessary to realize its promise and provide patient access. This study contributes to current literature, as possibly the first study to directly interview US payers on NGTS coverage and reimbursement. (shrink)

The current study examined youths’ and their parents’ perceptions concerning participation in an investigation of spontaneous and induced pain during recovery from laparoscopic appendectomy. Youth and their parents independently completed surveys about their study participation. On a scale from 0 to 10, both parents and youth rated their experience as positive. Among youth, experience ratings did not differ by pain severity and survey responses did not differ by age. Most youth reported that they would tell another youth to participate. Ethical (...) issues regarding instigation of pain in youth for research purposes are examined. (shrink)

The increasing complexity of human subjects research and its oversight has prompted researchers, as well as institutional review boards, to have a forum in which to discuss challenging or novel ethical issues not fully addressed by regulations. Research ethics consultation services provide such a forum. In this article, we rely on the experiences of a national Research Ethics Consultation Collaborative that collected more than 350 research ethics consultations in a repository and published 18 challenging cases with accompanying ethical commentaries to (...) highlight four contexts in which REC can be a valuable resource. REC assists: 1) investigators before and after the regulatory review; 2) investigators, IRBs, and other research administrators facing challenging and novel ethical issues; 3) IRBs and investigators with the increasing challenges of informed consent and risk/benefit analysis; and 4) in providing flexible and collaborative assistance to overcome study hurdles, mediate conflicts within a team, or directly engage with research participants. Institutions that have established, or plan to establish, REC services should work to raise the visibility of their service and engage in open communication with existing clinical ethics consult services as well as the IRB. While the IRB system remains the foundation for the ethical review of research, REC can be a valuable service for investigators, regulators, and research participants aligned with the goal of supporting ethical research.

Innovative, data-driven methods provide more rigorous and systematic evidence for the description and explanation of diachronic semantic processes. The volume systematises, reviews, and promotes a range of empirical research techniques and theoretical perspectives that currently inform work across the discipline of historical semantics. In addition to emphasising the use of new technology, the potential of current theoretical models (e.g. within variationist, sociolinguistic or cognitive frameworks) is explored along the way.

In recounting some of the key sociological insights offered by over 30 years of research on emotion management, or emotion regulation, we orient our discussion around sociological answers to the following questions: What is emotion management? How does emotion management occur? Why does it occur? And what are its consequences or benefits? In this review, we argue that emotion and its management are profoundly social. Through daily interactions with others, individuals learn to differentiate which emotions are appropriate when, as well (...) as the most effective ways to bring their feelings in line with culturally agreed-upon emotion norms. Emotion management is also functional, not only for the individuals who perform it, but also for the dyads, groups, institutions, and societies in which they are embedded. The social processes through which individuals learn to display culturally appropriate emotions have important implications on many levels, from interpersonal interactions to the development of social movements.

The Bermuda Principles for DNA sequence data sharing are an enduring legacy of the Human Genome Project. They were adopted by the HGP at a strategy meeting in Bermuda in February of 1996 and implemented in formal policies by early 1998, mandating daily release of HGP-funded DNA sequences into the public domain. The idea of daily sharing, we argue, emanated directly from strategies for large, goal-directed molecular biology projects first tested within the “community” of C. elegans researchers, and were introduced (...) and defended for the HGP by the nematode biologists John Sulston and Robert Waterston. In the C. elegans community, and subsequently in the HGP, daily sharing served the pragmatic goals of quality control and project coordination. Yet in the HGP human genome, we also argue, the Bermuda Principles addressed concerns about gene patents impeding scientific advancement, and were aspirational and flexible in implementation and justification. They endured as an archetype for how rapid data sharing could be realized and rationalized, and permitted adaptation to the needs of various scientific communities. Yet in addition to the support of Sulston and Waterston, their adoption also depended on the clout of administrators at the US National Institutes of Health and the UK nonprofit charity the Wellcome Trust, which together funded 90% of the HGP human sequencing effort. The other nations wishing to remain in the HGP consortium had to accommodate to the Bermuda Principles, requiring exceptions from incompatible existing or pending data access policies for publicly funded research in Germany, Japan, and France. We begin this story in 1963, with the biologist Sydney Brenner’s proposal for a nematode research program at the Laboratory of Molecular Biology at the University of Cambridge. We continue through 2003, with the completion of the HGP human reference genome, and conclude with observations about policy and the historiography of molecular biology. (shrink)

Boys and men tend to underperform in language education, and they are also underrepresented in language-related fields. Research suggests that stereotypes can affect students’ performance and sense of belonging in academic subjects and test settings via stereotype threat. For example, girls and women sometimes underperform on math tests following reminders that math is for boys. We sought to test whether stereotypes that women have better language skills than men would affect men. In a series of four experiments (N = 542), (...) we tested the effect of explicit stereotype threats on men’s performance in language-related tasks, and their sense of belonging to language-related domains. We found little evidence for stereotype threat effects on men in language. Bayesian analysis suggested that the null hypothesis was consistently more likely than the alternative, and mini-meta analyses showed effect sizes near zero. Future research should explore other explanations for gender gaps in language. (shrink)

Participant safety and data integrity, critical in trials of new investigational drugs, are achieved through honest participant report and precision in the conduct of procedures. HIV prevention post-trial access studies in middle-income countries potentially offer participants many benefits including access to proven efficacious but unlicensed technologies, ancillary care that often exceeds local standards-of-care, financial reimbursement for participation and possibly unintended benefits if participants choose to share or sell investigational drugs. This case study examines the possibility that this combination of benefits (...) may constitute an undue inducement for some participants in middle-income countries, where economic challenges are prevalent. A case study is presented of a single participant in a cohort of 382 participants who used concealment, fabrication and deception to ensure eligibility for a post-trial access study of an unlicensed HIV prevention technology at potential risk to her health and that of her fetus. A root cause analysis revealed her desire to access HIV prevention during an unplanned pregnancy with a partner whose faithfulness was in question.
