Incomplete information is a commonly cited barrier to the adoption of new innovations. We present a decision-making experiment, conducted with farmers in the field, that explores the extent to which information which reduces ambiguity may be provided as a public good. In the experiment, participants make a series of decisions between a risky gamble and an ambiguous gamble. An initial private decision is followed by second choice in which participants know that their chosen gambles and outcomes will be publicly but (...) anonymously revealed. Selection of the ambiguous option in this decision thus provide public good information which can be used to update beliefs about the ambiguous gamble. After the public revelation, participants make one final choice between the two options which we use to assess learning. We also test communication as a mechanism to increase provision of the public good. We find evidence that people with preference to avoid ambiguity contribute to public good information while risk averse people free ride. Communication does not affect the overall public good provision, either in a positive or negative direction. Finally, we find that people draw appropriate inference from the information that the public good provides. We relate our findings to the issue of new technology adoption in agriculture which is of particular importance for our participants. (shrink)

ABSTRACT Previous research has consistently highlighted the importance of stakeholder engagement in identifying and developing solutions to ethical challenges in genomic research, especially in Africa where such research is relatively new. In this paper, we examine what constitutes good ethical practice in research, from the perspectives of genomic research participants in Uganda. Our study was part of a multi-site qualitative study exploring these issues in Uganda, Ghana and Zambia. We purposively sampled various stakeholders including genomic research participants, researchers, research ethics (...) committee members, policy makers and community members. This paper presents the findings from in-depth interviews with 27 people with diabetes who had participated in a diabetes genomic study. Data were collected using semi-structured interviews. Manual thematic content analysis was conducted using a framework approach. Findings indicate three key requirements that research participants see as vital for genomic research to be more responsive to research participants’ needs and contextual realities: (1) de-emphasising the role of experts and institutions in the consenting process, (2) clarity about the timing and nature of feedback both of findings relevant to the health of individuals and about the broad progress of the study, and (3) more effective support for research participants during and after the study.

Artists, art critics, art historians, and cognitive psychologists have asserted that visual artists perceive the world differently than nonartists and that these perceptual abilities are the product of knowledge of techniques for working in an artistic medium. In support of these claims, Kozbelt (2001) found that artists outperform nonartists in visual analysis tasks and that these perceptual advantages are statistically correlated with drawing skill. We propose a model to explain these results that is derived from a diagnostic framework for object (...) recognition and recent research in cognitive neuroscience on selective visual attention. This research demonstrates that endogenous shifts of visual attention enhance the encoding of expected features in the visual field and inhibit the perception of potential distracters. Moreover, it demonstrates complementary roles for spatial schemata and motor plans in visual attention. We argue that artists develop novel spatial schemata, which enable them to recognize and reproduce stimulus features sufficient for adequate artistic production in a medium, and that these schemata become encoded as motor plans as artists develop technical proficiency in a medium. We hypothesize that artists' perceptual advantages can therefore, be explained by the role spatial schemata and motor plans play in selective attention. (shrink)

Condorcet's classic jury theorem shows that when the members of a group have noisy but independent information about what is best for the group as a whole, majority decisions tend to outperform dictatorial ones. When voting is supplemented by communication, however, the resulting interdependencies between decision-makers can strengthen or undermine this effect: they can facilitate information pooling, but also amplify errors. We consider an intriguing non-human case of independent information pooling combined with communication: the case of nest-site choice by honey (...) bee swarms. It is empirically well-documented that when there are different nest sites that vary in quality, the bees usually choose the best one. We develop a new agent-based model of the bees’ decision process and show that its remarkable reliability stems from a particular interplay of independence and interdependence between the bees.

To analyze the relations between art and science, philosophers and historians have developed different lines of inquiry. A first type of inquiry considers how artistic and scientific practices have interacted over human history. Another project aims to determine the contributions that scientific research can make to our understanding of art, including the contributions that cognitive science can make to philosophical questions about the nature of art. We rely on contributions made to these projects in order to demonstrate that art and (...) science are codependent phenomena. Specifically, we explore the codependence of art and science in the context of a historical analysis of their interactions and in the context of contemporary debates on the cognitive science of art.

In the philosophy of perception, olfaction is the perennial problem child, presenting a range of difficulties to those seeking to define its proper referents, and its phenomenological content. Here, we argue that many of these difficulties can be resolved by recognizing the object-like representation of odors in the brain, and by postulating that the basic objects of olfaction are best defined by their biological value to the organism, rather than physico-chemical dimensions of stimuli. Building on this organism-centered account, we speculate (...) that the phenomenological space of olfaction is organized into a number of coarse affective dimensions that apply categorically. This organization may be especially useful for coupling sensation to decision-making and instrumental action in a sensory modality where the stimulus space is especially complex and high-dimensional.

Neuroscience of art might give us traction with aesthetic issues. However it can be seen to have trouble modeling the artistically salient semantic properties of artworks. So if meaning really matters, and it does, even in aesthetic contexts, the prospects for this nascent field are dim. The issue boils down to a question of whether or not we can get a grip on the kinds of constraints present and available to guide interpretive behavior in our engagement with works of fine (...) art. I argue that biased competition models of selective attention can be used to solve this problem, generalize to the affective content of our responses to artworks, and so show that research in cognitive neuroscience is germane to the types of problems of interest within the philosophy of art.

A broad range of behavior is associated with crossmodal perception in the arts. Philosophical explanations of crossmodal perception often make reference to neuroscientific discussions of multisensory integration in selective attention. This research demonstrates that superior colliculus plays a regulative role in attention, integrating unique modality specific visual, auditory, and somatosensory spatial maps into a common spatial framework for action, and that motor skill, emotional salience, and semantic salience contribute to the integration of auditory, visual, and somatosensory information in ordinary perceptual (...) contexts. I present a model for multisensory integration in our engagement with artworks derived from a diagnostic recognition framework for object recognition and a biased competition model for selective attention. The proposed model attributes a role to superior colliculus in a broader fronto-parietal attentional network that integrates sensory information, primes perceptual systems to the expectation of stimulus features salient to particular sensorimotor or cognitive tasks at particular locations, and inhibits the perception of task irrelevant distracters. I argue that this model demonstrates that crossmodal effects are the rule not the exception in perception and discuss ways in which it explains a range of crossmodal effects in our engagement with pictures, dance, and musical performances.

Philosophical accounts of narrative fiction can be loosely divided into two types. Participant accounts argue that some sort of simulation, or 1st person perspective taking plays a critical role in our engagement with narratives. Observer accounts argue to the contrary that we primarily engage narrative fictions from a 3rd person point of view, as either side participants or outside observers. Recent psychological research suggests a means to evaluate this debate. The perception of distance and slope is influenced by the energetic (...) (e.g., task difficulty) and emotional (e.g., anxiety) costs of actions. These effects are limited to increases in the costs of actions agents intend to perform themselves, generalize to cases where participants imagine acting, and demonstrate a role for tacit motor simulation in action planning. If participant accounts are sound, one should, therefore, find similar effects across changes in the interpretation of the costs of actions depicted in static images. We asked people to copy the rough spatial layout of two paintings across different interpretations of the costs of the actions they depicted. We predicted that increasing costs would cause participants to draw distances as longer and hills as steeper. Our results confirm this prediction for the energetic, but not the emotional, costs of actions. (shrink)

What is it about art that can be so captivating? How is it that we find value in the often odd and abstract objects and events we call artworks? William P. Seeley proposes that artworks are attentional engines. They are artifacts that have been intentionally designed to direct attention to critical stylistic features that reveal their point, purpose, or meaning. In developing this view, Seeley argues that there is a lot we can learn about the value of art (...) from interdisciplinary research focused on our perceptual engagement with artworks. Recent breakthroughs in cognitive science and behavioral science can explain how we recognize artworks and how we differentiate them from more quotidian artifacts. Seeley pushes this line of reasoning, showing how cognitive science can help reveal the way artworks function as a unique source of value. Cognitive systems integrate this information into our experience of art, guiding attention and shaping what we perceive. Our understanding and appreciation of artworks is therefore carried in our perceptual experience of them. -/- Attentional Engines explores the pitfalls and potential of this interdisciplinary strategy for understanding art. It articulates a cognitivist theory of art grounded in perceptual psychology and neuroscience and demonstrates its application to a range of puzzles in the philosophy of the arts. This includes questions about the nature of depiction, the role played by metakinesis in dance appreciation, the nature of musical expression, and the power of movies. The provocative interdisciplinary theories Seeley presents will appeal to scholars and students interested in aesthetics, philosophy of mind, philosophy of art, cognitive science, and anyone with a burning curiosity about how artworks work.

Nurses practising in mental health are faced with challenging decisions concerning confidentiality if a patient is deemed a potential risk to self or others, because releasing pertinent information pertaining to the patient may be necessary to circumvent harm. However, decisions to withhold or disclose confidential information that are inappropriately made may lead to adverse outcomes for stakeholders, including nurses and their patients. Nonetheless, there is a dearth of contemporary research literature to advise nurses in these circumstances. Cognitive Continuum Theory presents (...) a single‐system intuitive‐analytical approach to examining and understanding nurse cognition, analogous to the recommended single‐system approach to decision‐making in mental health known as structured clinical judgement. Both approaches incorporate cognitive poles of wholly intuition and analysis and a dynamic continuum characterised by a ‘common sense’ blending of intuitive and analytical cognition, whereby cues presented to a decision‐maker for judgement tasks are weighed and assessed for relevance. Furthermore, Cognitive Continuum Theory promotes the importance of determining pattern recognition and functional relations strategies, which can be used to understand the operationalisation of nurse cognition.

BackgroundInformed consent as stipulated in regulatory human research guidelines requires that a volunteer is well-informed about what will happen to them in a trial. However researchers are faced with a challenge of how to ensure that a volunteer agreeing to take part in a clinical trial is truly informed. We conducted a qualitative study among volunteers taking part in two HIV clinical trials in Uganda to find out how they defined informed consent and their perceptions of the trial procedures, study (...) information and interactions with the research team.MethodsBetween January and December 2012, 23 volunteers who had been in the two trials for over 6 months, consented to be interviewed about their experience in the trial three times over a period of nine months. They also took part in focus group discussions. Themes informed by study research questions and emerging findings were used for content analysis.ResultsVolunteers defined the informed consent process in terms of their individual welfare. Only two of the volunteers reported having referred during the trial to the participant information sheets given at the start of the trial. Volunteers remembered the information they had been given at the start of the trial on procedures that involved drawing blood and urine samples but not information about study design and randomisation. Volunteers said that they had understood the purpose of the trial. They said that signing a consent form showed that they had consented to take part in the trial but they also described it as being done to protect the researcher in case a volunteer later experienced side effects.ConclusionVolunteers pay more attention during the consent process to procedures requiring biological tests than to study design issues. Trust built between volunteers and the research team could enhance the successful conduct of clinical trials by allowing for informal discussions to identify and review volunteers’ perceptions. These results point to the need for researchers to view informed consent as a process rather than an event. (shrink)

BackgroundMedical researchers in resource-constrained settings must make difficult moral decisions about the provision of ancillary care to participants where additional healthcare needs fall outside the scope of the research and are not provided for by the local healthcare system. We examined research stakeholder perceptions and experiences of ancillary care in biomedical research projects in Malawi. MethodsWe conducted 45 qualitative in-depth interviews with key research stakeholders: researchers, health officials, research ethics committee members, research participants and grants officers from international research funding (...) organisations. Thematic analysis was used to analyse and interpret the findings. FindingsAll stakeholders perceived the provision of ancillary care to have potential health benefits to study participants in biomedical research. However, they also had concerns, particularly related to the absence of guidance to support it. Some suggested that consideration for ancillary care provision could be possible on a case-by-case basis but that most of the support from research projects should be directed towards strengthening the public health system, emphasising public good above individual or personal benefits. Some researchers and ethics committee members raised concerns about potential tensions in terms of funding, for example balancing study demands with addressing participants’ additional health needs.ConclusionOur findings highlight the complexities and gaps in the guidance around the provision of ancillary care in Malawi and other resource-constrained settings more generally. To promote the provision of ancillary care, we recommend that national and international guidelines for research ethics include specific recommendations for resource-constrained settings and specific types of research.

BackgroundLimited research has been conducted on explanations and understandings of biobanking for future genomic research in African contexts with low literacy and limited healthcare access. We report on the findings of a sub-study on participant understanding embedded in a multi-disease community health screening and biobank platform study known as ‘Vukuzazi’ in rural KwaZulu-Natal, South Africa.MethodsSemi-structured interviews were conducted with research participants who had been invited to take part in the Vukuzazi study, including both participants and non-participants, and research staff that (...) worked on the study. The interviews were transcribed, and themes were identified from the interview transcripts, manually coded, and thematically analysed.ResultsThirty-nine individuals were interviewed. We found that the research team explained biobanking and future genomic research by describing how hereditary characteristics create similarities among individuals. However, recollection and understanding of this explanation seven months after participation was variable. The large volume of information about the Vukuzazi study objectives and procedures presented a challenge to participant recall. By the time of interviews, some participants recalled rudimentary facts about the genetic aspects of the study, but many expressed little to no interest in genetics and biobanking.ConclusionParticipant’s understanding of information related to genetics and biobanking provided during the consent process is affected by the volume of information as well as participant’s interest in the subject matter being discussed. We recommend that future studies undertaking biobanking and genomic research treat explanations of this kind of research to participants as an on-going process of communication between researchers, participants and the community and that explanatory imagery and video graphic storytelling should be incorporated into theses explanations as these have previously been found to facilitate understanding among those with low literacy levels. Studies should also avoid having broader research objectives as this can divert participant’s interest and therefore understanding of why their samples are being collected. (shrink)

Psychological studies (Proffitt, 2006) have demonstrated that what one sees is influenced by one's goals, physiological state, and emotions. These studies demonstrate that there is a positive correlation between the physical demands (energetic cost) and perceived valence (emotional cost) of a task and the appearance of slant and egocentric distance in the environment. The studies are compelling. However, one can question whether their results are due to changes in the way participants perceived the orientation and extent of their environment or (...) are instead artifacts of the way they judged the difficulty of expected tasks in particular contexts. We asked participants to sketch the rough spatial layout of several paintings as accurately as possible. In this type of task participants continuously compare what they have drawn against what they perceive. Therefore, participants performance can be interpreted as a means to directly measure of the spatial metric of perception. We chose two paintings by Andrew Wyeth as target images: “Christina's World” and “Winter, 1946.” Participants were asked to draw the spatial arrangement of the key features of the scene depicted in the target painting twice: prior to being presented with biographical information about the subject of the painting condition; and then again after being told the biographical information that altered the perceived task demands or emotional valence of the events they depicted. We predicted that participants' drawings would differ in the two conditions indicating that: change in the energetic or emotional costs of the depicted action would cause them to perceive the depicted orientation of hills as steeper and distance between key landmarks as longer. Results from the energetic cost condition support this prediction. We will discuss our results and the suggestion that these types of effects reflect a role for motor simulation in perception (Witt, 2005). (shrink)

BackgroundLiterature on issues relating to comprehension during the process of obtaining informed consent (IC) has largely focused on the challenges potential participants can face in understanding the IC documents, and the strategies used to enhance comprehension of those documents. In this review, we set out to describe the factors that have an impact on comprehension and the strategies used to enhance the IC process in sub-Saharan African countries.MethodsFrom November 2021 to January 2022, we conducted a literature search using a PRISMA (...) tool. We searched electronic databases (PubMed, EMBASE, EBSCOHOST) to identify relevant peer reviewed studies. We then reviewed the references of these articles to find additional literature that might have been missed through the initial search. We were particularly interested in full text articles in English that focused on the IC process in SSA published between 2006 and 2020. We included systematic reviews, and studies from Western and Asian countries that included data about SSA. We excluded articles that focused on medical interventions and studies that did not require IC.ResultsOut of the 50 studies included most were multi-country (n = 13) followed by single country studies in South Africa (n = 12); Kenya, Tanzania, Uganda (n = 5) each; Gambia, Ghana and Nigeria (n = 2)each ; and one each for Botswana, Malawi, Mali, Mozambique. We identified three areas of focus: (1) socio-cultural factors affecting IC; (2) gaps in the ethical and legal frameworks guiding the IC process; and (3) strategies used to improve participants’ understanding of IC.ConclusionOur review showed wide recognition that the process of achieving IC in SSA is inherently challenging, and there are limitations in the strategies aimed at improving comprehension in IC. We suggest that there is a need for greater flexibility and negotiation with communities to ensure that the approach to IC is suited to the diverse socio-cultural contexts. We propose moving beyond the literal translations and technical language to understanding IC comprehension from the participants’ perspectives and the researchers’ views, while examining contextual factors that impact the IC process.

Increasing attention is being paid to the potential of anti-retroviral treatment for HIV prevention. The possibility of eliminating HIV from a population through a universal test and treat intervention, where all people within a population are tested for HIV and all positive people immediately initiated on ART, as part of a wider prevention intervention, was first proposed in 2009. Several clinical trials testing this idea are now in inception phase. An intervention which relies on universally testing the entire population for (...) HIV will pose challenges to human rights, including obtaining genuine consent to testing and treatment. It also requires a context in which people can live free from fear of stigma, discrimination and violence, and can access services they require. These challenges are distinct from the field of medical ethics which has traditionally governed clinical trials and focuses primarily on patient researcher relationship. This paper sets out the potential impact of a population wide treatment as prevention intervention on human rights. It identifies five human right principles of particular relevance: participation, accountability, the right to health, non-discrimination and equality, and consent and confidentiality. The paper proposes that explicit attention to human rights can strengthen a treatment as prevention intervention, contribute to mediating likely health systems challenges and offer insights on how to reach all sections of the population.

To improve the value of pharmaceutical spending, some manufacturers and payers have introduced outcomes-based contracts, where rebates are tied to specified outcomes. We reviewed the literature and interviewed key experts to assess these contracts' potential to slow pharmaceutical spending. We found that while outcomes-based contracts are increasingly common in the US, they are still limited by multiple factors — including the lack of meaningful outcomes data. Moreover, there is no evidence to date that they slow pharmaceutical spending or increase access. (...)

Artworks are attentional engines, or artifacts intentionally designed to direct attention to formal features that are diagnostic for their artistically salient aesthetic, expressive, and semantic content. This is nowhere more true than the movies. Moving pictures are constructed from a suite of formal and narrative devices carefully developed to capture, hold, and direct our attention. These devices are tools for developing content by controlling the way information is presented throughout the duration of our engagement with a movie. In this respect (...) moving pictures are analogous to visual routines used to direct and bias attention in natural behavior - they are artifacts used to deliver information on the fly as it is needed for the development of the narrative. This article reviews some of the fundamental devices movie makers use to discharge this function - such as variable framing and criterial prefocusing – and discusses their relation to our underlying cognitive, affective, and neurological architecture. These formal devices are designed to guide and control salient aspects of viewers behavioral responses to mass market movies. Therefore, we argue that it is no surprise to discover that that they are fine tuned to the architecture of emotion, perception, and cognition. (shrink)

Empirical aesthetics and philosophy of art are often framed as disciplines in conflict with one another. Psychologists working in empirical aesthetics argue that philosophical theories of art reflect the evaluative biases of critics and experts and so fail as objective accounts of artistic practice. Philosophers argue that the causal-psychological explanations appealed to in empirical aesthetics can not account for the role normative conventions play in appreciative judgements, and so fail to differentiate artworks and artistic practices from ordinary artifacts and behaviors. (...) I argue that this putative conflict can be dissolved by paying attention to the productive role shared normative conventions play in our perceptual engagement with works of fine art. I sketch a hierarchical theory derived from a biased competition account of selective attention that can be used to model these cognitive influences in our engagement with artworks. (shrink)

It has been argued that motion picture theory, or as we prefer to call it theory of the moving image, is too abstract, generalized , or theoretical to be of use for movie makers and critics interested in the production and analysis of particular films. We apply the framework and resources of Cognitivist Film Theory to explain some of the particular ways that Alfred Hitchcock's Rear Window works to engage audiences with an eye to allaying the skeptics doubts.
