Despite significant scholarly debate about knowledge production in the management discipline through the peer-review journal processes, there is minimal discussion about the ethical treatment of the research subject in these publication processes. In contrast, the ethical scrutiny of management research processes within research institutions is often highly formalized and very focused on the protection of research participants. Hence, the question arises of how management publication processes should best account for the interests of the research subject, both in the narrow sense (...) of specific research participants and in the broader understanding of the subject of the research. This question is particularly pertinent in light of significant codification of research ethics within academic institutions, and increasing self-reflection within the management discipline about the “good” of management research and education. Findings from a survey and interviews with management journal editors reveal a complex scenario; many editors believe that a formalized requirement within the journal publication process may have detrimental outcomes and, in fact, diminish the ethical integrity of management scholarship. Building on these findings, this paper argues that ethical concern for the research subject merely in terms of institutional rule compliance and avoidance of harm to individual participants is insufficient, and calls for explicitly positive engagement with both the individual and the collective subject of management research should receive due ethical consideration. An alternative model involving reflexive ethical consideration of research subjects across the publication process—with implications for role of authors, reviewers, editors, and research subjects—is outlined.

Launch of clinical investigation represents a substantial escalation in commitment to a particular clinical translation trajectory; it also exposes human subjects to poorly understood interventions. Despite these high stakes, there is little to guide decision-makers on the scientific and ethical evaluation of early phase trials. In this article, we review policies and consensus statements on human protections, drug regulation, and research design surrounding trial launch, and conclude that decision-making is largely left to the discretion of research teams and sponsors. We (...) then review what is currently understood about how research teams exercise this discretion, and close by laying out a research agenda for characterizing the way investigators, sponsors, and reviewers approach decision-making in early phase research.

The rapid growth of next-generation genetic sequencing has prompted debate about the responsibilities of researchers toward genetic incidental findings. Assuming there is a duty to disclose significant incidental findings, might there be an obligation for researchers to actively look for these findings? We present an ethical framework for analyzing whether there is a positive duty to look for genetic incidental findings. Using the ancillary care framework as a guide, we identify three main criteria that must be present to give rise (...) to an obligation to look: high benefit to participants, lack of alternative access for participants, and reasonable burden on researchers. Our analysis indicates that there is no obligation to look for incidental findings today, but during the ongoing translation of genomic analysis from research to clinical care, this obligation may arise.

Background:Ideas of patient involvement are related to notions of self-determination and autonomy, which are not always in alignment with complex interactions and communication in clinical practice.Aim:To illuminate and discuss patient involvement in routine clinical care situations in nursing practice from an ethical perspective.Method:A case study based on an anthropological field study among patients with advanced cancer in Denmark.Ethical considerations:Followed the principles of the Helsinki Declaration.Findings:Two cases illustrated situations where nurses refused patient involvement in their own case.Discussion:Focus on two ethical issues, (...) namely ‘including patients’ experiences in palliative nursing care’ and ‘relational distribution of power and knowledge’, inspired primarily by Hannah Arendt’s concept of thoughtlessness and a Foucauldian perspective on the medical clinic and power. The article discusses how patients’ palliative care needs and preferences, knowledge and statements become part of the less significant background of nursing practice, when nurses have a predefined agenda for acting with and involvement of patients. Both structurally conditioned ‘thoughtlessness’ of the nurses and distribution of power and knowledge between patients and nurses condition nurses to set the agenda and assess when and at what level it is relevant to take up patients’ invitations to involve them in their own case.Conclusion:The medical and institutional logic of the healthcare service sets the framework for the exchange between professional and patient, which has an embedded risk that ‘thoughtlessness’ appears among nurses. The consequences of neglecting the spontaneous nature of human action and refusing the invitations of the patients to be involved in their life situation call for ethical and practical reflection among nurses. The conditions for interaction with humans as unpredictable and variable challenge nurses’ ways of being ethically attentive to ensure that patients receive good palliative care, despite the structurally conditioned logic of healthcare.

‘Client involvement’ has been a mantra within health policies, education curricula and healthcare institutions over many years, yet very little is known about how ‘client involvement’ is practised in home‐care services. The aim of this article is to analyse ‘client involvement’ in practise seen from the positions of healthcare professionals, an elderly person and his relative in a home‐care setting. A sociologically inspired single case study was conducted, consisting of three weeks of observations and interviews. The study has a focus (...) on the relational aspects of home care and the structural, political and administrative frames that rule home‐ care practice. Client involvement is shown within four constructed analytical categories: ‘Structural conditions of providing and receiving home care’; ‘Client involvement inside the home: performing a professional task and living an everyday life’; ‘Client involvement outside the home: liberal business and mutual goal setting’; and ‘Converting a home to a working place: refurnishing a life’. The meaning of involvement is depending on which position it is viewed from. On the basis of this analysis, we raise the question of the extent to which involvement of the client in public home‐care practice remains limited. (shrink)

In their article published in Nanoethics, “Ethical, Legal and Social Aspects of Brain-Implants Using Nano-Scale Materials and Techniques”, Berger et al. suggest that there may be a prima facie moral obligation to improve neuro implants with nanotechnology given their possible therapeutic advantages for patients [Nanoethics, 2:241–249]. Although we agree with Berger et al. that developments in nanomedicine hold the potential to render brain implant technologies less invasive and to better target neural stimulation to respond to brain impairments in the near (...) future, we argue against presenting the development of nanobionic clinical devices in terms of a moral obligation to conduct this research. In the first part of the paper, we consider what a duty to pursue new technologies might mean, and in the second we explore some of the negative consequences of defending such development as a moral obligation based on potential benefit. We argue that promoting the advances available to brain implants through developments in nanotechnology and bionics could contribute to medical rhetoric that indirectly increases the risk of exposing patients to harm when participating in clinical trials. We argue that rather than there being a moral obligation to improve nanobionics implants because of their potential benefit, the pursuit of improved neuro implants must be balanced against the prima facie obligations to protect patients against harm and to promote and protect patient autonomy.

Pediatric biobanking is considered important for generating biomedical knowledge and improving health care. However, the inclusion of children’s samples in biobanks involves specific ethical issues. One of the main concerns is how to appropriately engage children in the consent procedure. We suggest that children should be involved through a personalized assent procedure, which means that both the content and the process of assent are adjusted to the individual child. In this paper we provide guidance on how to put personalized assent (...) into pediatric biobanking practice and consider both the content and process of personalized assent. In the discussion we argue that the assent procedure itself is formative. Investing in the procedure should be a requirement for pediatric biobank research. Although personalized assent will require certain efforts, the pediatric community must be aware of its importance. The investment and trust earned can result in ongoing engagement, important longitudinal information, and stability in/for the research infrastructure, as well as increased knowledge among its participants about research activity. Implementing personalized assent will both respect the child and support biobank research. (shrink)

The exportation of unethical practices to low- and middle-income countries has been conceived as a prevalent practice which needs to be examined more closely. Such a practice might point towards the exploitation of vulnerable population groups. We conducted a survey among Mexican research ethics committee members to explore the issue of ethics dumping in Mexico by understanding how its existence and contributing factors and norms are perceived by these ethics committee members. We designed an exploratory survey based on a five-point (...) Likert scale, following an established, validated and published methodology. The questionnaire included both open close-ended questions. The aspects covered in the questionnaire were introductory questions on the existence of ethical issues; general perception on ethics dumping in Mexico; lack of voluntariness, undue inducement, and therapeutic misconception as exploitation risks; existence of exploitative practices; norms facilitating ethics dumping; acceptable levels of benefit to Mexico; boundaries of ethics dumping. The survey was administered to a sample of research ethics committee members from public and private Mexican hospitals in 2016. Most of the ethics committee members believed clinical trials are generally ethically sound, though almost a majority think that ethics dumping is a common occurrence and that it is a serious issue. Most agree that ethics dumping needs to be addressed. They also identified other issues such as ethical issues related to patient participation and ethics committees. Further, most committee members agree that undue inducement and therapeutic misconception affect voluntariness, and that both individuals and communities receive appropriate benefits. From the perspective of Mexican research ethics committee members, ethics dumping commonly exists in Mexican clinical trials, as well as several related issues such as ethical issues on patient participation and ethics committees, as well as voluntariness issues. Further, most members believed these issues need to be addressed. However, most were also of the opinion that clinical trials are generally ethically compliant. This points to the need for further studies on the reasons for these perspectives. (shrink)

This paper explores some key discrepancies between two sets of normative requirements applicable to the research use of personal data and human biological materials: the data protection regime which follows the application of the European Union General Data Protection Regulation, and the Declaration of Helsinki, CIOMS guidelines and other research ethics regulations. One source of this controversy is that the GDPR requires consent to process personal data to be clear, concise, specific and granular, freely given and revocable and therefore has (...) challenged the concept of ‘broad consent’, which has been widely applied in the context of biobanking. Another source of controversy is the interplay between regulations of research ethics and protection of personal data related to the secondary use of personal data and biological materials. In this case, the GDPR ‘research condition’ provides an alternative to re-consent for the use of previously collected personal data and biological materials. Although the mentioned controversies have been raised in the legal literature, they have not been explicitly addressed from the research ethics perspective. Should consent be regarded as a priority legal basis for personal data processing in health data research? Can broad consent still be a suitable legal ground for biobanking? What should be the role of research ethics provisions that differ from the GDPR standards, and what should be the role and function of research ethics committees in the changing environment of health data research? These are the ongoing controversies to be explored in the paper. (shrink)

Hilden and Gammelgaard's comments on the evaluation and application of statistical trials and on informed consent lead to the same conclusion that there are special circumstances when clinical trials are performed in emergency situations.The decision to comment on the work that H&G responded to was motivated by the wish to manifest the need to reach a consensus on modifying the conditions in which clinical trials should be performed in special circumstances.One unquestionable fact must first be addressed: clinical trials are necessary (...) for acquiring new knowledge and consequent improvements in health care services. At the same time, patient participation should be encouraged under conditions that respect patients' decision making capability.Are these conditions being met at present?

German medical schools have not yet sufficiently introduced students to the field of good scientific practice. In order to prevent scientific misconduct and to foster scientific integrity, courses on GSP must be an integral part of the curriculum of medical students. Based on a review of the literature, teaching units and materials for two courses on GSP were developed and tested in a pilot course. The pilot course was accompanied by a pre-post evaluation that assessed students’ knowledge and attitudes towards (...) scientific integrity and scientific misconduct. A syllabus was designed that comprised the following six topics: theoretical foundations of GSP; scientific publishing; empirical data; scientific supervision and teamwork; clinical research; personal interests. The comparison pre versus post-intervention yielded statistically significant changes in regard to the participants’ knowledge and attitude toward all forms of scientific misconduct treated in the course. As the majority of participants was not familiar with the fundamental regulations or guidelines of GSP, it seems crucial to train students in actively applying such norms to real-world conflicts. Students’ unfamiliarity with the fundamentals of GSP can be linked to the fact that many students have already experienced forms of scientific misconduct. Thus, GSP syllabi should be closely adjusted to a student’s realm of experience. All in all, courses on GSP can be seen as a potential means to increase the number of young scholars. (shrink)

This paper offers a critical analysis of several accounts of the placebo effect that have been put forward. While the placebo effect is most often thought of as a control in research and as a deceptive tool in practice, a growing body of research suggests that it ought to be thought of as a powerful phenomenon in its own right. Several accounts that aim to draw boundaries around the placebo effect are evaluated in relation to current evidence and it is (...) argued that none of them adequately capture the variability and potency of the phenomenon. Two accounts, however, that point towards the underlying mechanisms of the placebo effect, are shown to offer promise in terms of developing a more comprehensive account of the placebo effect.

The rapid growth of pharmaceutical markets in the 20th century has increased the demand for human research participants in clinical trials. However, with the globalization of clinical research, most clinical trials are conducted in low-income countries (LICs) with political and economic instability, and lack of basic healthcare, but easy access to human subjects. This paper explores the unique ethical challenges faced during the pre-enrollment phase of cross-cultural research in a country like Pakistan, and how these challenges make the Pakistani population (...) vulnerable to exploitation. It also outlines recommendations regarding conducting research in Pakistan within ethical parameters adopted according to local culture. This discussion is important because researchers must focus on the pre-enrollment phase of the research process for it’s cultural suitability and acceptability so that the research conducted is credible and valid and has social value for the research population.

Software plays an important role in contemporary research. Aside from its use for administering traditional instruments like surveys and in data analysis, the widespread use of mobile and web apps for social, medical and lifestyle engagement has led to software becoming a research intervention in its own right. For example, it is not unusual to find apps being studied for their utility as interventions in health and social life. Since the software may persist in use beyond the life of an (...) investigation, this raises questions as to the extent of ethical duties for researchers involved in its production and/or study towards the participants involved. Key factors identified include the extent of affect created by the software, the effect it has on a participant’s life, the length of investigation, cost of maintenance and participant agency. In this article we discuss the issues raised in such situations, considering them in the context of post-research duties of care and suggesting strategies to balance the burden on researchers with the need for ongoing participant support.

The feasibility of alternate ethical models is discussed and found wanting.

Consequently, the question is not whether (...) this system of ethics should be applied but rather how it can be applied most sensitively, appropriately, and wisely. The remainder of this article discusses of how the authors have attempted to do so in each stage of their own research with Hispanic immigrants to the United States. (shrink)

Background Despite recent developments aimed at creating international guidelines for ethical global health research, critical disconnections remain between how global health research is conducted in the field and the institutional ethics frameworks intended to guide research practice. Discussion In this paper we attempt to map out the ethical tensions likely to arise in global health fieldwork as researchers negotiate the challenges of balancing ethics committees’ rules and bureaucracies with actual fieldwork processes in local contexts. Drawing from our research experiences with (...) an implementation and evaluation project in Jamaica, we argue that ethical research is produced through negotiated spaces and reflexivity practices that are centred on relationships between researchers and study participants and which critically examine issues of positionality and power that emerge at multiple levels. In doing so, we position ethical research practice in global health as a dialectical movement between the spoken and unspoken, or, more generally, between operationalized rules and the embodied relational understanding of persons. Summary Global health research ethics should be premised not upon passive accordance with existing guidelines on ethical conduct, but on tactile modes of knowing that rely upon being engaged with, and responsive to, research participants. Rather than focusing on the operationalization of ethical practice through forms and procedures, it is crucial that researchers recognize that each ethical dilemma encountered during fieldwork is unique and rooted in social contexts, interpersonal relationships, and personal narratives.

Large prospective biobanks are being established containing DNA, lifestyle and health information in order to study the relationship between diseases, genes and environment. Informed consent is a central component of research ethics protection. Disclosure of information about the research is an essential element of seeking informed consent. Within biobanks, it is not possible at recruitment to describe in detail the information that will subsequently be collected because people will not know which disease they will develop. It will also be difficult (...) to describe the specific research that will be performed using the biobank, other than to stipulate categories of research or diseases that are not included. Potential subjects can only be given information about the sorts of research that will be performed and by whom. Organisations responsible for biobanks usually argue that this disclosure of information is adequate when seeking informed consent, especially if coupled with a right to withdraw, as it would not be feasible or it would be too expensive to seek consent renewal on a regular basis. However, there are concerns about this ‘blanket consent’ approach’. Consent waivers have also been proposed in which research subjects entrust their consent with an independent third party to decide whether subsequent research using the biobank is consistent with the original consent provided by the subject.

Men often make riskier decisions than women across a wide range of real-life behaviors. Whether this sex difference is accentuated, diminished, or stable under stressful conditions is, however, contested in the scientific literature. A critical blind spot lies amid this contestation: Most studies use standardized, laboratory-based, cognitive measures of decision making rather than complex real-life social simulation tasks to assess risk-related behavior. To address this blind spot, we investigated the effects of acute psychosocial stress on risk decision making in men (...) and women using a standardized cognitive measure and a novel task that simulated a real-life social situation. Participants were exposed to either an acute psychosocial stressor or an equivalent control condition. Stressor-exposed participants were further characterized as high- or low-cortisol responders. Results confirmed that the experimental manipulation was effective. On the IGT, participants characterized as low-cortisol responders made significantly riskier decisions than those characterized as high-cortisol responders. Similarly, in the online chatroom, participants characterized as low-cortisol responders were, relative to those in the Non-Stress group, significantly more likely to make risky decisions. Together, these results suggest that at lower levels of cortisol both men and women tend to make riskier decisions in both economic and social spheres. (shrink)

BackgroundGenome-wide association studies (GWAS) provide a powerful means of identifying genetic variants that play a role in common diseases. Such studies present important ethical challenges. An increasing number of GWAS is taking place in lower income countries and there is a pressing need to identify the particular ethical challenges arising in such contexts. In this paper, we draw upon the experiences of the MalariaGEN Consortium to identify specific ethical issues raised by such research in Africa, Asia and Oceania.DiscussionWe explore ethical (...) issues in three key areas: protecting the interests of research participants, regulation of international collaborative genomics research and protecting the interests of scientists in low income countries. With regard to participants, important challenges are raised about community consultation and consent. Genomics research raises ethical and governance issues about sample export and ownership, about the use of archived samples and about the complexity of reviewing such large international projects. In the context of protecting the interests of researchers in low income countries, we discuss aspects of data sharing and capacity building that need to be considered for sustainable and mutually beneficial collaborations.SummaryMany ethical issues are raised when genomics research is conducted on populations that are characterised by lower average income and literacy levels, such as the populations included in MalariaGEN. It is important that such issues are appropriately addressed in such research. Our experience suggests that the ethical issues in genomics research can best be identified, analysed and addressed where ethics is embedded in the design and implementation of such research projects.

Considerations of justice and concern for well-being support conducting mental health research and addressing ethical concerns specific to mental health research are critical. We discuss these concerns, provide recommendations to enable the ethical conduct of mental health research, and argue that participants’ interests should be given primary weight in resolving apparent dilemmas. We also comment on provisions of two legislative actions in India relevant to mental health research: Rights of Persons with Disability Act 2016 and the Mental Health Care Act (...) 2017. Both conform to the 2006 United Nations Convention on Rights of Persons with Disabilities of which India is a signatory. Both provide protections and enumerate rights relevant to people with mental health conditions but with differing focus. The commonalities and differences between the three are discussed in the background of international literature on research in mental health conditions. Studies involving deception and future directions for ethical requirements regarding genetic research are discussed. (shrink)

The main question explored by the book is: How can cross-border access to human genetic resources, such as blood or DNA samples, be governed in such a way as to achieve equity for vulnerable populations in developing countries? The book situates the field of genomic and genetic research within global health and research frameworks, describing the concerns that have been raised about the potential unfairness in exchanges during recent decades. Access to and sharing in the benefits of human biological resources (...) are aspects not regulated by any international legal framework such as the Convention on Biological Diversity, which applies only to the exchange of plants, animals and microorganisms, as well as to associated traditional knowledge. Examples of genetic research perceived as exploitative are provided in order to illustrate the legal vacuum concerning the global governance of human genetic resources. The main conclusions drawn from the legal and ethical analysis are: - Benefit sharing is crucial in order to avoid the exploitation of developing countries in human genetic research. - With functioning research ethics committees, undue inducement is less of a concern in genetic research than in other areas of medical research (e.g. clinical trials). - Concerns remain over research involving indigenous populations; accordingly, recommendations are provided. In drawing these conclusions, the book addresses in detail a highly pressing topic in global bioethics and international law. In this regard, it combines bioethical arguments with jurisprudence, in particular with reference to the law of equity and the legal concepts of duress (coercion), unconscionable dealing, and undue inducement.

Experimental design is one aspect of a scientific method. A well-designed, properly conducted experiment aims to control variables in order to isolate and manipulate causal effects and thereby maximize internal validity, support causal inferences, and guarantee reliable results. Traditionally employed in the natural sciences, experimental design has become an important part of research in the social and behavioral sciences. Experimental methods are also endorsed as the most reliable guides to policy effectiveness. Through a discussion of some of the central concepts (...) associated with experimental design, including controlled variation and randomization, this chapter will provide a summary of key ethical issues that tend to arise in experimental contexts. In addition, by exploring assumptions about the nature of causation and by analyzing features of causal relationships, systems, and inferences in social contexts, this chapter will summarize the ways in which experimental design can undermine the integrity of not only social and behavioral research but policies implemented on the basis of such research.

The purpose of this dissertation is to identify some of the most pressing problems in the dominant contemporary approach to research ethics, and to devise an alternative approach that avoids these problems. I contend that the fundamental ethical values invoked in human research are often appealed to in contradictory or ambiguous ways, or in ways that do not adequately capture or do not show an adequate understanding of the specific ethical concerns of human research. One significant problem in this domain (...) is that values for ethical research are often unreflectively imported from medical therapy, producing ill-suited guidelines that cannot capture the different ethical situations that arise in the context of research. Furthermore, ethical guidelines in this area are often not developed with a sufficient understanding of the deep philosophical issues that they invoke. I suggest that we can address these problems through examining the fundamental ethical concerns of research on a philosophical level. This method will reveal severe problems with the approach to two of the ethical values underlying research; beneficence and respect for autonomy (or respect for persons). Once the nature of these problems has been revealed, and with reference to ethical problems that typically arise in the domain of research, I construct a coherent philosophical foundation for research ethics, which both avoids these deep-seated problems and better captures the ethical issues that arise in the domain of human research. I argue that we need to radically depart from the values of beneficence and autonomy/respect for persons as they are currently understood in the guidelines. We need an idea of beneficence that is clearly distinct from that which is used in the therapeutic medical context from which this notion is currently drawn. I also contend that we need to move away from autonomy as a central value in research ethics. I posit an alternative choice-based approach to informed consent which is concerned both with respecting agents’ freedom of choice, and also with their wellbeing, as providing a good means of protecting and promoting the interests of the individual research subject. Although these two imperatives are often thought to clash on a fundamental level, I will show that, in research ethics, they can be reconciled with minimal conflict. Though this represents a departure from the ethics of medical therapy, this approach is far more suited to the context of research. This theoretical basis for informed consent can help to clarify the ethical problems that are specific to this domain and provide us with relevant ethical guidance in research ethics. (shrink)

In the first half of this dissertation, I develop a heuristic methodology for analyzing scientific solutions to the problem of underdetermination. Heuristics are rough-and-ready procedures used by scientists to construct models, design experiments, interpret evidence, etc. But as powerful as they are, heuristics are also error-prone. Therefore, I argue that they key to prudently using a heuristic is the articulation of meta-heuristics---guidelines to the kinds of problems for which a heuristic is well- or ill-suited. Given that heuristics will introduce certain (...) errors into our scientific investigations, I emphasize the importance of a particular category of meta-heuristics involving the search for robust evidence. Robustness is understood to be the epistemic virtue bestowed by agreement amongst multiple modes of determination. The more modes we have at our disposal, and the more these confirm the same result, the more confident can we be that a result is not a mere artifact of some heuristic simplification. Through an analysis of case-studies in the philosophy of biology and clinical trials, I develop a principled method for modeling and evaluating heuristics and robustness claims in a qualitative problem space. The second half of the dissertation deploys the heuristic methodology to address ethical and epistemological issues in the science of clinical trials. To that end, I develop a network model for the problem space of clinical research, capable of representing the various kinds of experiments, epistemic relationships, and ethical justifications intrinsic to the domain. I then apply this model to ongoing research with the antibacterial agent, moxifloxacin, for the treatment of tuberculosis, tracking its development from initially successful and promising in vitro and animal studies to its disappointing and discordant performance across five human efficacy trials. Given this failure to find a robust result with moxifloxacin across animal and human studies, what should researchers now do? While my final analysis of this case does not definitively answer that question, I demonstrate how my methodology, unlike a statistical meta-analysis, helps to clarify the directions for further research.

The present work is concerned with a phenomenon referred to as contextual cueing. In visual search, if a searched-for target object is consistently encountered within a stable spatial arrangement of distractor objects, detecting the target becomes more efficient over time, relative to non-repeated, random arrangements. This effect is attributed to learned target-distractor spatial associations stored in long-term memory, which expedite visual search. This Thesis investigates four aspects of contextual cueing: Study 1 tackled the implicit-explicit debate of contextual cueing from a (...) new perspective. Previous studies tested explicit access to learned displays by applying a recognition test, asking observers whether they have seen a given display in the previous search task. These tests, however, typically yield mixed findings and there is an on-going controversy whether contextual cueing can be described as an implicit or an explicit effect. The current study applied the new perspective of metacognition to contextual cueing and combined a contextual cueing task with metacognitive ratings about the clarity of the visual experience, either of the display configuration or the target stimulus. Bayesian analysis revealed that there was an effect of repeated context on metacognitive sensitivity for configuration, but not target, ratings. It was concluded that effects of contextual memory on metacognition are content-specific and lead to increased metacognitive access to the display configuration, but not to the target stimulus. The more general implication is that from the perspective of metacognition, contextual cueing can be considered as an explicit effect. Study 2 aimed at testing how explicit knowledge affects memory-guided visual search. Two sets of search displays were shown to participants: explicit and implicit displays. Explicit displays were introduced prior to the search experiment, in a dedicated learning session, and observers should deliberately learn these displays. Implicit displays, on the other hand, were first shown in the search experiment and learning was incidental through repeated exposure to these displays. Contextual cueing arising from explicit and implicit displays was assessed relative to a baseline condition of non-repeated displays. The results showed a standard contextual cueing effect for explicit displays and, interestingly, a negative cueing effect for implicit displays. Recognition performance was above chance for both types of repeated displays; however, it was higher for explicit displays. This pattern of results confirmed – in part – the predictions of a single memory model of attention-moderated associative learning, in which different display types compete for behavior and explicit representations block the retrieval of implicit representations. Study 3 investigates interactions between long-term contextual memory with short-term perceptual hypotheses. Both types of perceptual memory share high similarities with respect to their content, therefore the hypothesis was formulated that they share a common memory resource. In three experiments of interrupted search with repeated and non-repeated displays, it was shown that contextual cueing expedites performance in interrupted search; however, there was no interaction of contextual cueing with the generation or the confirmation of perceptual hypotheses. Rather, the analysis of fixational eye movements showed that long-term memory exerts its influence on search performance upon the first glance of a given display, essentially affecting the starting point of the search process. The behavior of approaching the target stimulus is then a product of generating and confirming perceptual hypotheses with these processes being unaffected by long-term contextual memory. It was concluded that long-term and short-term memory representations of the same search display are independent and exhibit additive effects on search performance. Study 4 is concerned with the effects of reward on perceptual learning. It was argued that rewarding repeated displays in a contextual cueing paradigm leads to an acceleration of the learning effect; however, it was not considered whether reward also has an effect in non-repeated displays. In these displays, at least the target position is kept constant while distractor configurations are random across repetitions. Usually this is done in order to account for target position-specific probability learning in contextual cueing. However, it is possible that probability learning itself is modulated by reward. The current experiment introduced high or low reward to repeated and importantly, also non-repeated displays. It was shown that reward had a huge effect on non-repeated displays, indicating that rewarding certain target positions, irrespective of the distractor layout, facilitates RT performance. Interestingly, reward effects were even larger for non-repeated compared to repeated displays. It was concluded that reward has a strong effect on probability-, and not context learning. (shrink)

The fourth amendment to the German Medicinal Products Act (Arzneimittelgesetz) states that nontherapeutic research in incompetent populations is permissible under the condition that potential research participants expressly declare their wish to participate in scientific research in an advance research directive. This article explores the implementation of advance research directives in Germany against the background of the international legal and ethical framework for biomedical research. In particular, it addresses a practical problem that arises from the disclosure requirement for advance research directives. (...) We show that, if the disclosure standard for advance research directives is set at a token level, nontherapeutic research in incompetent populations becomes practically impossible. To resolve this issue, we suggest the disclosure standard be set at a type level. (shrink)

This collection presents six case studies on the ethics of mental health research, written by scientific researchers and ethicists from around the world. We publish them here as a resource for teachers of research ethics and as a contribution to several ongoing ethical debates. Each consists of a description of a research study that was proposed or carried out and an in-depth analysis of the ethics of the study.
