Two experiments examined similarities and differences in the effects of consciously and unconsciously perceived rewards on the active maintenance of goal-relevant information. Participants could gain high and low monetary rewards for performance on a word span task. The reward value was presented supraliminally or subliminally at different stages during the task. In Experiment 1, rewards were presented before participants processed the target words. Enhanced performance was found in response to higher rewards, regardless whether they were presented supraliminally or subliminally. In (...) Experiment 2, rewards were presented after participants processed the target words, i.e., during maintenance. Performance increased in response to relatively high rewards when they were presented subliminally, but decreased when they were presented supraliminally. We conclude that both consciously and unconsciously perceived rewards boost resources supporting the maintenance of task-relevant information. Conscious processing of rewards can, however, heavily interfere with an ongoing maintenance process and impair performance. (shrink)

Recently, we showed that conscious and unconscious rewards affect the active maintenance of goal-relevant information differently. Here, we elaborate on the mechanisms enabling the boosting or disrupting effects of consciously processed high rewards, and discuss a few methodological and theoretical implications that may be worth considering in future research on the role of reward processing in working memory performance.

The Middle English Partonope of Blois possesses two characteristics which are more in keeping with twelfth-century French romance than with fifteenth-century English literature: a strong focus on place and the forceful presence of the heroine. Both Melior and her city undergo a substantial shift in identity: Melior is transformed from a dominating woman who seeks to control the hero into a more passive figure; Chef d'Oire changes both in character — from being an otherworldly magical place with its own independent (...) sense of time to a tournament venue more grounded in reality — and in the terminology which is used to describe it. Throughout the work Melior and her city are portrayed as interdependent and inseparable, and in order to convert the initially subversive and powerful Melior into a more conventional romance heroine it is also necessary to adapt the image of her city.

The conscientious refusal to dispense emergency contraception is legally protected in fourteen states. While the ethical dimensions of these objections have been explored within moral and feminist philosophy, conscientious refusal to the over-the-counter sale of EC has not been significantly studied through an egalitarian lens, especially with attention to the existing reproductive healthcare landscape in which these refusals occur. This article argues, through Amartya Sen’s capability approach, that conscientious refusal to EC creates a burdensome inequality for people wishing to prevent (...) pregnancy that manifests within a background of historical injustices, elevating its importance in our weighing of capabilities.

In our commentary we ask whether we should ultimately endeavour to find the deep causes of behaviours? Then we discuss two extensions of the proposed framework: (1) Mendelian randomisation and (2) hypothesis-free gene–environment interaction (leveraging heterogeneity in genetic associations). These complementary methods help move us towards second-generation causal knowledge, ultimately understanding mechanistic pathways and identifying more effective intervention targets.

Two aspects of dynamic systems approaches that are pertinent to developmental models of reading are the emergence of a system with self-organizing characteristics, and its evolution over time to a stable state that is not easily modified or perturbed. The effects of dynamic stability may be seen in the differences obtained in the processing of print by beginner readers taught by different approaches to reading (phonics and text-centered), and more long-term effects on adults, consistent with these differences. However, there is (...) little direct evidence collected over time for the same participants. In this study, lexicalized (implicit) phonological processing, and explicit phonological and letter-sound skills are further examined in a precocious reader whose early development at 3 and 5 years has been extensively described (Cognition, 2000, 2004). At ages 10 and 14 years, comparisons were made with these earlier reports and skilled adult readers, using the same tasks for evidence of changes in reading processes. The results showed that along with an increase of reading accuracy and speed, her pattern of lexicalized phonological responses for reading did not change over time. Neither did her pattern of explicit phonological and letter-sound skills, aspects of which were inferior to her lexicalized phonological processing, and word reading. These results suggest dynamic stability of the word reading system. The early emergence of this system with minimal explicit skill development calls into question developmental reading theories that require such skills for learning to read. Currently, only the Knowledge Sources theory of reading acquisition can account for such findings. Consideration of these aspects of dynamic systems raise theoretical issues that could result in a paradigm shift with regard to best practice and intervention. (shrink)

This paper explores the relationship between individual work values and unethical decision-making and actual behavior at work through two complementary studies. Specifically, we use a robust and comprehensive model of individual work values to predict unethical decision-making in a sample of working professionals and accounting students enrolled in ethics courses, and IT employees working in sales and customer service. Study 1 demonstrates that young professionals who rate power as a relatively important value are more likely to violate professional conduct guidelines (...) despite receiving training regarding ethical professional principles. Study 2, which examines a group of employees from an IT firm, demonstrates that those rating power as an important value are more likely to engage in non-work-related computing even when they are aware of a monitoring software that tracks their computer usage and an explicit policy prohibiting the use of these computers for personal reasons.

During the past decade teamwork in manufacturing, as in other sectors, has become the organisational form of choice. In contrast to earlier manifestations such as autonomous workgroups some 30 years earlier, this appears to have been largely for business and production reasons rather than being directly aimed at improving the quality of work life. Taken from part of a larger study of teamworking in several different manufacturing companies this paper draws upon a retrospective analysis of cases of self-managed team implementation (...) in UK manufacturing. Examples of good and bad practice and consequent guidance have been identified where the weight of evidence gives confidence in their general applicability. A basis for benchmarking is provided, related to preparation, implementation and maintenance of self-managed teams in manufacturing. Key gaps identified are for tools to assist in early functional analysis, leadership decisions and boundary setting, and appropriate team performance measurement and reward systems. (shrink)

Nearly $2 trillion is spent annually in the U.S. treating chronic illness — yet accessibility to quality health care services in rural communities for the chronically ill and dying remains problematic. Unique barriers present special challenges to a meaningful discussion of and subsequent strategies for addressing these issues in the context of increasingly scarce resources.

The Institute of Medicine reporting on the quality of health care in America recommends six aims for achieving the health care system we could have. Together with the Institute for Healthcare Improvement Triple Aim initiative, a framework has emerged to challenge providers, educators, and policymakers to remake the health care system according to specific objectives: to provide care that is safe, effective, patient-centered, timely, efficient, and equitable to more people at a price we can afford. Complicating this mission of better (...) prevention and better care at a lower cost is a daunting demographic: January of 2011 marked the month and year that the first of the baby boomers turned 65. The U.S. Census Bureau in May 2010 projected the number of Americans of this age and over to reach 88 million by 2050, more than double the current figure of 40.2 million. Parekh and Barton forecast in stark detail what it will be like to address these burgeoning numbers of older Americans with comorbidities, including the fact that over 20% of the population currently experiences at least two chronic medical conditions.

Research using the intermodal preferential looking paradigm (IPLP) has consistently shown that English‐learning children aged 2 can associate transitive argument structure with causal events. However, studies using the same methodology investigating 2‐year‐old children’s knowledge of the conjoined agent intransitive and semantic role assignment have reported inconsistent findings. The aim of the present study was to establish at what age English‐learning children have verb‐general knowledge of both transitive and intransitive argument structure using a new method: the forced‐choice pointing paradigm. The results (...) suggest that young 2‐year‐olds can associate transitive structures with causal (or externally caused) events and can use transitive structure to assign agent and patient roles correctly. However, the children were unable to associate the conjoined agent intransitive with noncausal events until aged 3;4. The results confirm the pattern from previous IPLP studies and indicate that children may develop the ability to comprehend different aspects of argument structure at different ages. The implications for theories of language acquisition and the nature of the language acquisition mechanism are discussed. (shrink)

Comparing mortuary rituals across 57 representative cultures extracted from the Human Relations Area Files, this paper demonstrates that kin of the deceased engage in behaviours to prepare the deceased for disposal that entail close and often prolonged contact with the contaminating corpse. At first glance, such practices are costly and lack obvious payoffs. Building on prior functionalist approaches, we present an explanation of corpse treatment that takes account of the unique adaptive challenges entailed by the death of a loved one. (...) We propose that intimate contact with the corpse provides the bereaved with extensive veridical cues of death, thereby facilitating acceleration of a grieving process that serves to recategorize the deceased as no longer a relationship partner, opening the door to relationship replacement and a return to social functioning. The benefits of exposure to such cues are tempered by the costs of exposure to cues of disease risk, a balance that in part explains the relative rarity of highly invasive mortuary practices that exacerbate the latter factor. We conclude by discussing implications of our model for contemporary mortuary practices in the developed world. (shrink)

The aim of this chapter is to address the role of memory in past-life convictions. Although it is commonly accepted in the modern media - and popular western culture more generally - that people believe they have lived before because the memory contains detailed verifiable facts, little is known about how people actually reason about the veracity of their previous existence. To our knowledge, the current project is the most extensive research that probes the role of memory in past life (...) convictions. More specifically, we explore two questions. First, to what extent does memory lead to past-life belief, and is this conviction based on external validation or via the episodic sense of personal identity contained in the memory? Second, what is the conception of self on which one's current self is taken to be the same as the past-life self? -/- In what follows, we propose that memory plays an important role in convincing people that they have lived before. Fundamentally, this memory is episodic insofar as it represents the event as happened to the encoder. This memory contrasts with semantic memory - memory of facts...Further, we contend that it is the episodic sense of personal identity (rather than external validation) that typically contributes to the belief in a past life. Finally, we argue that the conception of self implicated in past-life belief is the non-trait conception. Of course, this fits naturally with the idea that the belief in a past life issues partly from the episodic sense of identity, since it is the non-trait conception of self that is implicated in the episodic sense of identity... -/- Our proposal in this chapter can be construed as a psychological extension of Reid's point in the context of past-life belief. People assume that they are the same person as someone in earlier times, despite large variations in the traits between those individuals, and they think this partly because of the testimony of their episodic memory. If our account is correct, then it makes the belief in a past life less bizarre, at least psychologically. For we are suggesting that the episodic sense of personal identity that led to your conviction that you existed at the time of your sixteenth birthday celebrations some decades ago, is also involved in other people's convictions that they existed 200 years ago. This proposal is also situated in recent cognitive approaches to the study of religion and religious experiences, which suggests that extraordinary convictions are often underpinned by the ordinary processes of social cognition (e.g. see Barrett 2000; Barrett 2007; Boyer 2001; Lawson and McCauley 1990; for reincarnation, see White Forthcoming-a,-b).

There is considerable evidence that beliefs in supernatural punishment decrease self-interested behavior and increase cooperation amongst group members. To date, research has largely focused on beliefs concerning omniscient moralistic gods in large-scale societies. While there is an abundance of ethnographic accounts documenting fear of supernatural punishment, there is a dearth of systematic cross-cultural comparative quantitative evidence as to whether belief in supernatural agents with limited powers in small-scale societies also exert these effects. Here, we examine information extracted from the Human (...) Relations Area Files on cultural discourse about the recently deceased, local ancestor spirits, and mortuary practices across 57 representative cultures. We find evidence that in traditional small-scale societies ancestor spirits are commonly believed to be capable of inflicting harm, with many attendant practices aimed at mitigating this danger. However, such beliefs do not appear to promote cooperation, as ancestor spirits seem to be concerned with interactions between themselves and the living, and to prioritize their own welfare. Many attendant practices are inconsistent even with bipartite cooperation with ancestors that could be viewed as a model for other relationships. The broader implications of this research for the cultural evolution of religion are discussed. (shrink)
