Recent years have seen a renewed interest in the philosophical study of information. In this paper a two-part analysis of information gain—objective and subjective—in the context of doxastic change is presented and discussed. Objective information gain is analyzed in terms of doxastic movement towards true belief, while subjective information gain is analyzed as an agent’s expectation value of her objective information gain for a given doxastic change. The resulting expression for subjective (...) information gain turns out to be a familiar one with well-known formal properties: the Kullback–Leibler divergence. The two notions of information are discussed and the suggested measure of subjective information gain is then compared with the widely held view that information gain equals uncertainty reduction.

Current theories propose that our sense of curiosity is determined by the learning progress or information gain that our cognitive system expects to make. However, few studies have explicitly tried to quantify subjective information gain and link it to measures of curiosity. Here, we asked people to report their curiosity about the intrinsically engaging perceptual ‘puzzles’ known as Mooney images, and to report on the strength of their aha experience upon revealing the solution image (curiosity relief). (...) We also asked our participants (279) to make a guess concerning the solution of the image, and used the distribution of these guesses to compute the crowdsourced semantic entropy (or ambiguity) of the images, as a measure of the potential for information gain. Our results confirm that curiosity and, even more so, aha experience is substantially associated with this semantic information gain measure. These findings support the expected information gain theory of curiosity and suggest that the aha experience or intrinsic reward is driven by the actual information gain. In an unannounced memory part, we also established that the often reported influence of curiosity on memory is fully mediated by the aha experience or curiosity relief. We discuss the implications of our results for the burgeoning fields of curiosity and psychoaesthetics. (shrink)

This article considers an asymmetric contest with incomplete information. There are two types of players: informed and uninformed. Each player has a different ability to translate effort into performance in terms of the contest success function. While one player’s type is known to both players, the other is private information and known only to the player himself. We compare the Bayesian Nash equilibrium outcome of a one-sided private information contest to the Nash equilibrium with no private (...) class='Hi'>information, in which both players know the type of the other player. We show conditions under which uncertainty increases the investment of the uninformed player and the rent dissipation of the contest, while decreasing the expected net payoff of the informed player. In addition, we consider conditions under which the informed player—before knowing his own type—prefers that the uninformed player knows his type. Moreover, we show conditions for the existence/non-existence of equilibrium in a two-stage contest in which the informed player declares his type (or does not declare) in the first stage and in the second stage the two players play according to the information available to them.

Semantic networks were developed in cognitive science and artificial intelligence studies as graphical knowledge representation and inference tools emulating human thought processes. Formal analysis of the representation and inference capabilities of the networks modeled them as subsets of standard first-order logic (FOL), restricted in the operations allowed in order to ensure the tractability that seemed to characterize human reasoning capabilities. The graphical network representations were modeled as providing a visual language for the logic. Sub-sets of FOL targeted on knowledge representation (...) came to be called description logics, and research on these logics has focused on issues of tractability of subsets with differing representation capabilities, and on the implementation of practical inference systems achieving the best possible performance. Semantic network research has kept pace with these developments, providing visual languages for knowledge entry, editing, and presenting the results of inference, that translate unambiguously to the underlying description logics. This paper discusses the design issues for such semantic network formalisms, and illustrates them through detailed examples of significant generic knowledge structures analyzed in the literature, including determinables, contrast sets, genus/differentiae, taxonomies, faceted taxonomies, cluster concepts, family resemblances, graded concepts, frames, definitions, rules, rules with exceptions, essence and state assertions, opposites and contraries, relevance, and so on. Such examples provide important test material for any visual language formalism for logic. (shrink)

We examined affection-giving, affection-denying, respect-giving, and respect-denying behaviors among men and women in heterosexual relationships. In a pilot study, although we had expected the latent variables of affectionate and respectful behaviors to emerge from exploratory factor analyses, we obtained the latent variables of socioemotional rewards and costs instead. In the main study, we replicated the factor patterns of socioemotional rewards and costs in confirmatory factor analyses. Moreover, we entered men’s and women’s self-reported narcissism alongside men’s and women’s socioemotional rewards (...) and costs, as reported by partners, into a dyadic model that we tested via covariance structure analyses. Results revealed that, although men and women reciprocated rewards as well as costs, narcissism was not reflected in the patterns of reciprocity We discuss implications for studies of relationship processes as two-person group dynamics.

It is widely assumed by scholars that Christ was in error on such matters as an expectation that the final judgement and its accompanying events would occur within the timeframe of a generation. While accepting that Christ did indeed prophesy his return within this timeframe, a recent co-authored work When the Son of Man Didn't Come aims to defend the veracity of his prophecy by drawing on the same historical-critical method that has given rise to doubts about it. The authors (...) propose a distinction between Mosaic and Jeremianic prophecy, arguing that Christ's was of the latter kind, which was present in the Ancient Near East, the Old and New Testaments, and other Jewish and Christian authors. Their argument, however, is at risk of reducing the truthfulness of a prophecy to its success. Hence this article explores a further distinction between two kinds of prophecy made in Thomas Aquinas's account of the truthfulness of prophecy, mapping it onto the Mosaic-Jeremianic distinction, and arguing that, in view of this linking of Aquinas's understanding of prophecy to the argument of the book, the book certainly adds to the set of proposed theological explanations of how Christ's prophecy of his return was true.

Gain-of-function research involves experimentation that aims or is expected to increase the transmissibility and/or virulence of pathogens. Such research, when conducted by responsible scientists, usually aims to improve understanding of disease causing agents, their interaction with human hosts, and/or their potential to cause pandemics. The ultimate objective of such research is to better inform public health and preparedness efforts and/or development of medical countermeasures. Despite these important potential benefits, GOF research can pose risks regarding biosecurity and biosafety. In (...) 2014 the administration of US President Barack Obama called for a “pause” on funding of GOF experiments involving influenza, SARS, and MERS viruses in particular. With announcement of this pause, the US Government launched a “deliberative process” regarding risks and benefits of GOFR to inform future funding decisions—and the US National Science Advisory Board for Biosecurity was tasked with making recommendations to the US Government on this matter. As part of this deliberative process the National Institutes of Health commissioned this Ethical Analysis White Paper, requesting that it provide review and summary of ethical literature on GOFR, identification and analysis of existing ethical and decision-making frameworks relevant to the evaluation of risks and benefits of GOFR, decision-making about the conduct of GOF studies, and the development of US policy regarding GOFR, and development of an ethical and decision-making framework that may be considered by NSABB when analyzing information provided by GOFR risk-benefit assessment, and when crafting its final recommendations. The ethical and decision-making framework ultimately developed is based on the idea that there are numerous ethically relevant dimensions upon which any given case of GOFR can fare better or worse : research imperative, proportionality, minimization of risks, manageability of risks, justice, good governance, evidence, and international outlook and engagement. Rather than drawing a sharp bright line between GOFR studies that are ethically acceptable and those that are ethically unacceptable, this framework is designed to indicate where any given study would fall on an ethical spectrum—where imaginable cases of GOFR might range from those that are most ethically acceptable, at one end of the spectrum, to those that are most ethically problematic or unacceptable, at the other. The aim should be that any GOFR pursued should be as far as possible towards the former end of the spectrum. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Living Organ Donors’ Stories: (Unmet) Expectations about Informed Consent, Outcomes, and CareElisa J. Gordon, Symposium EditorKeywordsEthics, informed consent, kidney, liver, living donor, narrative, transplantationLiving donor organ transplantation has become standard treatment for patients with end-stage kidney or end-stage liver disease. Live donors comprised approximately 5,769 (34%) and 247 (4%) of all kidney and liver transplants in 2011, respectively (OPTN/UNOS). The reasons why people donate, the perception that donating does (...) not entail a decision per se, and the attendant fears and anxieties living donors feel about donating, have all been previously well investigated (Lennerling, Forsberg, Meyer, & Nyberg, 2004; Papachristou, Walter, Frommer, & Klapp, 2010). But much less is known about how donors experienced the overall donation process including the donor evaluation, preparation, appreciation of risks, decision-making, informed consent, post-operative, recovery processes, and the impact of donating on all aspects of their life, from their point of view. Thus, a narrative approach is essential for gaining insights into these less well known phenomena.There is good reason to remain concerned about the safety and ethical basis of living donation considering that living donors undergo serious health risks for no direct medical benefit to themselves (Ethics Committee of the Transplantation Society, 2004; Laird, 2012; Neergaard, 2011; Ratner & Sandoval, 2010; Shelton, 2011). The situation raises serious ethical questions specifically about nonmaleficence and informed consent, and more broadly about using people as a means to an end. The absence of long-term information may not undermine a willing donor’s commitment to save a loved one’s life, but is certainly cause for concern among transplant clinicians who want to be sure to disclose information that may be material for donors in order to provide adequate informed consent. In other words, the disjuncture between what transplant clinicians find important to disclose to donors and what prospective donors need to know—which follows along the lines of what Elliot Mishler referred to as the ‘voice of medicine’ versus the ‘voice of the lifeworld’(1984)—seems to complicate donors’ preparation for donation. Donors’ stories are important for addressing these concerns by identifying risks that typically do not get reported in the scientific literature—perhaps owing to a different [End Page 1] conceptualization of what should be construed as noteworthy risks—as well as by demonstrating how personal situations can enhance or detract from the experience overall.This issue of Narrative Inquiry in Bioethics (NIB) affords a unique entrée into both the often heard and unheard stories of living organ donors. A set of topical areas were presented for the authors’ consideration that relate to the donation process in general and the informed consent process more specifically: whether donors were prepared to donate; comprehended what they were told; could have understood the process better, as well as, the impact of donation on health, employment, finances, and personal relationships (Table 1). When soliciting donors’ stories, every effort was made to include a full range of experiences—both good and bad—from a variety of donors: kidney donation, liver donation, adult-to-adult and adult-to-child donation, related, unrelated, directed and anonymous (also known as ‘altruistic’ or ‘good Samaritan’ donors), paired chain exchange, and list exchange (Table 2)—in order to present a balanced perspective on live donation. Additionally, this issue includes a full breadth of stories about the donor experience, ranging from positive to mixed to negative (Table 3). While donors were given tremendous leeway in what stories they told, they were asked to focus their narratives on the lesser known dimensions of donation—the experience of it. While additional stories from liver donors would have helped to underscore common concerns among liver donors, we only received a few. Some of the donors are themselves health care professionals, active in the United Network for Organ Sharing (UNOS) or their local OPO, or have leveraged their experiences to help others by becoming a donor buddy or donor advocate.

In lieu of an abstract, here is a brief excerpt of the content:Gaining a Heart But Missing MyselfLeilani R. GrahamI gathered it in my hands as it fell from my hair-brush, too saturated to hold anymore. It felt as if I were inside a movie and waiting for someone to yell “Cut!” but no call came. It continued to fall, feather-like onto the ground, individual strands glinting in the light of the bathroom window. My hair, nearly all of it, was (...) gone.Between the time of my heart transplant and the moment my hair began to fall out, I arguably had suffered enough. Transplant brought four open-heart surgeries, ten days on ECMO, an intra-aortic balloon pump, delirium, necrotizing pneumonia, and so much muscular atrophy that I had to re-learn how to walk. CPR, broken ribs, and the scar of a tricuspid clip from a botched biopsy: it was not the miracle I was hoping for.The internal trauma had certainly taken its toll. I no longer knew how I really felt, thanks to copious pain meds that altered my mind and body. Each limb was foreign as I re-acclimated to how one grabs hold of a cup, signs their name, touches their legs. Externally, I was a mess: covered in deep purple bruises across my torso from the diabetes treatments, dead skin pooling in unwashed pores, my ankles swollen and indiscernible from my legs. But lacking a good mirror (or the desire to find one), I still felt like “myself” during my forty-five day hospital stay. I could feel my cheekbones protruding from thinning skin, saw through unfocused eyes from the tempestuous blood sugars, and my hair sat in a rat’s nest atop my head; but I was still me.Arriving home, I felt like a newborn being brought into the real world for the first time. I needed help with everything—showers, sitting up, putting on shoes, even going to the bathroom. At age twenty-four, I felt I had regressed to the point of no return as I relied on others to do the simplest tasks. In addition, I was quarantined inside for three months, due to the risk of obtaining a fungal infection from the outside. Caged, and alone in my body, I a trapped and wounded tiger: angry, hurting, and scared. [End Page 109]When I had been prepared for transplant—and I use “prepared” loosely because the information packet I was handed was insulting at best—I knew to expect the scars. I had no issue with that, having been cut open at my throat and chest for previous surgeries. I knew to expect a 12-inch line from neck to navel: the most evident sign I would now carry that I was disabled.What I did not expect were the bullet holes— the sealed entrances of thick chest tubes that now dotted my lower torso. I did not anticipate the bruises on my arms and groin from arterial pokes. I felt violated as if I had walked into some kind of abduction and was rolled out, beaten, bruised, and, worst, touched.But it wasn’t the physical trauma that hurt the most. It was that no one seemed surprised.Immediately after transplant, the team’s focus is purely on survival. Survive the 30 days post-surgery. Survive the year. Metrics, uncomfortably tied to transplant center success statistics, funding, and clout have little to do with the patients themselves. What did I care to only survive a year? I wanted years. I wanted decades. It felt I wanted more than anyone was willing to pay attention to.The conversation was narrowed to high-risk issues: infection, rejection, or other life-threatening conditions. While this makes sense on a clinical level, what constitutes a major event for a clinician may not be of the same emotional value to the patient. In my case, I was less occupied by how the steroids were working and more obsessed with their side effects, such as how much weight I was rapidly gaining. I walked into the clinic one day with the beginnings of stretch marks and a week later had claw-like ripples down my sides. My mood swings were explosive... (shrink)

In recent years, a multitude of datasets of human–human conversations has been released for the main purpose of training conversational agents based on data‐hungry artificial neural networks. In this paper, we argue that datasets of this sort represent a useful and underexplored source to validate, complement, and enhance cognitive studies on human behavior and language use. We present a method that leverages the recent development of powerful computational models to obtain the fine‐grained annotation required to apply metrics and techniques from (...) Cognitive Science to large datasets. Previous work in Cognitive Science has investigated the question‐asking strategies of human participants by employing different variants of the so‐called 20‐question‐game setting and proposing several evaluation methods. In our work, we focus on GuessWhat, a task proposed within the Computer Vision and Natural Language Processing communities that is similar in structure to the 20‐question‐game setting. Crucially, the GuessWhat dataset contains tens of thousands of dialogues based on real‐world images, making it a suitable setting to investigate the question‐asking strategies of human players on a large scale and in a natural setting. Our results demonstrate the effectiveness of computational tools to automatically code how the hypothesis space changes throughout the dialogue in complex visual scenes. On the one hand, we confirm findings from previous work on smaller and more controlled settings. On the other hand, our analyses allow us to highlight the presence of “uninformative” questions (in terms of Expected Information Gain) at specific rounds of the dialogue. We hypothesize that these questions fulfill pragmatic constraints that are exploited by human players to solve visual tasks in complex scenes successfully. Our work illustrates a method that brings together efforts and findings from different disciplines to gain a better understanding of human question‐asking strategies on large‐scale datasets, while at the same time posing new questions about the development of conversational systems.

This article addresses the value of information that affects the ambiguity faced by a decision maker. Our analysis is applied to the case of a farmer whose production can be damaged by a pest attack with unknown probability, this damage being reduced if the farmer decides to use a pesticide. Early warning systems have precisely been implemented in many countries to help farmers avoid inappropriate decisions in terms of pesticide use. We investigate, both theoretically and experimentally, how farmers value (...) these systems.

Her decision to self-insure or not depends on risk and ambiguity attitudes. We compile and compare the value of two types of information leading to a reduction of ambiguity and analyze their properties with respect to ambiguity attitude. Both types of information are valued positively if the farmer is ambiguity averse. We conduct a framed field experiment in which farmers and agricultural students have to decide whether or not to apply pesticides depending on risk, ambiguity and the associated monetary gains resulting from pesticide cost. The experimental findings support the theory. The average value of information among all participants is between €0.9/ha and €3.3/ha depending on the information gain. (shrink)

In recent decades scholars have acknowledged that transactions in the informal economy have not vanished with modernization and industrialization as expected but rather remain an important contemporary aspect of overall production and consumption across the world, in both developing and developed countries. Yet little is known about the profile of the consumers in this realm or what drives them to purchase from the informal economy. A systematic review of the literature investigating consumption in the informal economy reveals a severely (...) underdeveloped area of consumer studies with significant gaps in terms of its theoretical approaches, methods and regional coverage. The findings of the existing literature is that multiple motives are used by consumers for justifying their purchases in the informal economy beyond the dominant simplistic view that they do simply for financial gain or for a lower price. The outcome is a recognition that responsibility to reducing this phenomenon with negative effects on governments, businesses, workers and consumers lies not just with public authorities but also practitioners who need to correct the failures in formal market provision. The significant gaps identified in the literature are then used to highlight a comprehensive future research agenda, which includes the need for the development of an institutionalist theoretical perspective when explaining consumers‘ participation in the informal economy and social marketing interventions.

Informed consent is one of the most important ethical and legal principles in the United States, including Texas, and reflects a profound respect for individuals and their ability to make decisions in their own best interest. It is also a critical underpinning of medical practice, although how it is actually carried out has not been well studied. A survey was conducted in the private practices and a hospital in the Texas Medical Center in Houston, Texas to ascertain how physicians, patients (...) and patient's family members perceive and demonstrate the elements of informed consent. In-depth interviews of twelve physicians, three patients and three family members were carried out. For physicians, consent was an explicit and implicit aspect of virtually all medical practice. Physicians would seek patient input concerning medical decisions whenever possible and might also discuss care choices with families. However, they often made decisions based upon what they perceived as the patient's best interests. Patients expected the physician to involve them in the decision process, but whether they turned to family members, or even others to assist them, varied considerably. Although Texas physicians respect the competent patient as the primary decision maker, they may bypass a formal surrogate decision maker to gain input from others, including their own view of what is in the patient's best interest.

Recently, the outsourcing of Information Technology activities to offshore locations has been gaining significant momentum, with some associated backlash by the workforce in the United States. Based on their 2005 survey [6], Global Insight, a private consulting firm, estimated that U.S. companies will spend about $38.2 billion in offshore IT services by 2010, compared with about $15.2 billion in 2005, primarily because the expected cost savings will grow by $11.7 billion in the same time period. Binder writing in (...) "Foreign Affairs" [2] states that offshoring expenditures will continue to increase dramatically, and the changes the offshoring phenomenon will bring will transform society. This paper focuses on the social impact of offshoring and the effects of the weighing of costs and benefits as a result of offshoring activities. (shrink)

The diffusion of digital information and communication technologies is strongly supported by many countries of the world. Today, as well as in the past, new technologies are charged with high expectations, but at a closer look one can see that these expectations then are very different from now. Today they depend on the various interests of different groups of people. Globally acting enterprises see DICT as essential stra-tegic instruments in gaining competitive power; some governments hope to reach military hegemony, (...) others to control terrorism and crime, while grass root movements expect to become more influential on some aspects of society. The paper identifies and analyses basic tendencies which promote the various hopes: the effects of DICT on reducing production and transaction costs, and the possibility to transform information goods into marketable services or commodities. The final part of the paper is devoted to a few examples of how the potential of DICT can be used for social improvements. (shrink)

Capacity of conscious agents to perform genuine choices among future alternatives is a prerequisite for moral responsibility. Determinism that pervades classical physics, however, forbids free will, undermines the foundations of ethics, and precludes meaningful quantification of personal biases. To resolve that impasse, we utilize the characteristic indeterminism of quantum physics and derive a quantitative measure for the amount of free will manifested by the brain cortical network. The interaction between the central nervous system and the surrounding environment is shown to (...) perform a quantum measurement upon the neural constituents, which actualize a single measurement outcome selected from the resulting quantum probability distribution. Inherent biases in the quantum propensities for alternative physical outcomes provide varying amounts of free will, which can be quantified with the expected information gain from learning the actual course of action chosen by the nervous system. For example, neuronal electric spikes evoke deterministic synaptic vesicle release in the synapses of sensory or somatomotor pathways, with no free will manifested. In cortical synapses, however, vesicle release is triggered indeterministically with probability of 0.35 per spike. This grants the brain cortex, with its over 100 trillion synapses, an amount of free will exceeding 96 terabytes per second. Although reliable deterministic transmission of sensory or somatomotor information ensures robust adaptation of animals to their physical environment, unpredictability of behavioral responses initiated by decisions made by the brain cortex is evolutionary advantageous for avoiding predators. Thus, free will may have a survival value and could be optimized through natural selection. (shrink)

To date, technology has become so integral to our lives that it is almost impossible to imagine a day without using it. The digitization of society is gaining speed every day, affecting all areas of life: communication with people and the management of entire governments. To one degree or another, the use of digital technologies can be observed in every social institution on which society is built. The process includes social changes associated with introducing modern technologies into society and social (...) control. Since the second half of the XX century, the introduction of digital technologies has been seen as a means of overcoming temporal and spatial restrictions, the negatives of subjectivity that hinder the development of modern society. In the XXI century, the influence of digital technologies has grown significantly, which calls into question the sovereignty of the person himself as a social object. Undoubtedly, technology makes our lives much more accessible, with benefits such as saving time, accessing new information, and simplifying everyday life. However, the more social space is captured by objective digitalization, the more this space undergoes subjective influence. Digital technologies do not liberate the person from subjective control but, on the contrary, contribute to it. In the article, we consider how this happens in the field of the major social institutions of society, and possible vital consequences of this impact. (shrink)

Categorical loudness scaling (CLS) measures provide useful information about an individual’s loudness perception across the dynamic range of hearing. A probability model of CLS categories has previously been described as a multi-category psychometric function (MCPF). In the study, a representative “catalog” of potential listener MCPFs was used in conjunction with maximum-likelihood estimation to derive CLS functions for participants with normal hearing and with hearing loss. The approach of estimating MCPFs for each listener has the potential to improve the accuracy (...) of the CLS measurements, particularly when a relatively low number of data points are available. The present study extends the MCPF approach by using Bayesian inference to select stimulus parameters that are predicted to yield maximum expected information (MEI) during data collection. The accuracy and reliability of the MCPF-MEI approach were compared to the standardized CLS measurement procedure (ISO16832:2006). A non-adaptive, fixed-level, paradigm served as a “gold-standard” for this comparison. The test time required to obtain measurements in the standard procedure is a major barrier to its clinical uptake. Test time was reduced from approximately 15 minutes to approximately 3 minutes with the MEI-adaptive procedure. Results indicated that the test-retest reliability and accuracy of the MCPF-MEI adaptive procedures were similar to the standardized CLS procedure. Computer simulations suggest that the reliability and accuracy of the MEI procedure were limited by intrinsic uncertainty of the listeners represented in the MCPF catalog. In other words, the MCPF provided insufficient predictive power to significantly improve adaptive-tracking efficiency under practical conditions. Concurrent optimization of both the MCPF catalog and the MEI-adaptive procedure have the potential to produce better results. Regardless of the adaptive-tracking method used in the CLS procedure, the MCPF catalog remains clinically useful for enabling maximum-likelihood determination of loudness categories. (shrink)

This article will address the issue of using understandings of psychodynamic interrelations as a means to grasp how social and cultural dynamics are processed individually and collectively in narratives. I apply the two theoretically distinct concepts of inter- and intrasubjectivity to gain insight into how social and cultural dynamics are processed as subjective experiences and reflected in the interrelational space created in narrative interviews with trainee social educators. By using a combination of interactionist theory and psychosocial theory in the (...) analysis of an interview with a student of social education, I demonstrate how the often conflicting demands and expectations are being played out in the interrelational tension between the researcher (myself) and the interviewee or narrator. In a confrontation with "inner" expectations and concerns regarding a future profession and one's ability to cope, and the "outer" socially and culturally embedded discourses as they are played out in the objectives of self-development and education, the narrative about a forthcoming internship is filled with tension and contradiction. In this article I will demonstrate how such tensions and contradictions are valuable sources of information in understanding the process of becoming a social educator. (shrink)

The tendency to test outcomes that are predicted by our current theory (the confirmation bias) is one of the best-known biases of human decision making. We prove that the confirmation bias is an optimal strategy for testing hypotheses when those hypotheses are deterministic, each making a single prediction about the next event in a sequence. Our proof applies for two normative standards commonly used for evaluating hypothesis testing: maximizing expected information gain and maximizing the probability of falsifying (...) the current hypothesis. This analysis rests on two assumptions: (a) that people predict the next event in a sequence in a way that is consistent with Bayesian inference; and (b) when testing hypotheses, people test the hypothesis to which they assign highest posterior probability. We present four behavioral experiments that support these assumptions, showing that a simple Bayesian model can capture people's predictions about numerical sequences (Experiments 1 and 2), and that we can alter the hypotheses that people choose to test by manipulating the prior probability of those hypotheses (Experiments 3 and 4).

Armed conflict in Darfur, west Sudan since 2003 has led to the influx of about 100 international humanitarian UN and non-governmental organizations to help the affected population. Many of their humanitarian interventions included the collection of human personal data and/or biosamples, and these activities are often associated with ethical issues. A systematic review was conducted to assess the proportion of publicly available online reports of the research activities undertaken on humans in Darfur between 2004 and 2012 that mention obtaining ethical (...) approval and/or informed consent. This systematic review is based on a systematic literature search of Complex Emergency Database, ReliefWeb, PubMed), followed by a hand search for the hardcopies of the eligible reports archived in the Centre for Research on the Epidemiology of Disasters in Brussels. The online search showed that out of the 68 eligible studies, 13.2% reported gaining ethical approval and 42.6% that an informed consent was obtained from the participants. The CRED search included 138 eligible reports. None of these reports mentioned gaining ethical approval and 17 mentioned obtaining informed consent from their participants. The proportion of studies reporting ethical review and informed consent was smaller than might be expected, so we suggest five possible explanations for these findings. This review provides empirical evidence that can help in planning ethical conduct of research in humanitarian settings. (shrink)

M. Oaksford and N. Chater presented a Bayesian analysis of the Wason selection task in which they proposed that people choose cards in order to maximize expected information gain as measured by reduction in uncertainty in the Shannon-Weaver information theory sense. It is argued that the EIG measure is both psychologically implausible and normatively inadequate as a measure of epistemic utility. The article is also concerned with the descriptive account of findings in the selection task literature (...) offered by Oaksford and Chater. First, it is shown that their analysis data reported in the recent article of K. N. Kirby is unsound; second, an EIG analysis is presented of the experiments of P. Pollard and J. St. B. T. Evans that provides a strong empirical disconfirmation of the theory. (shrink)

The Adaptive Toolbox framework specifies heuristics for choice and categorisation that search through cues in previously learned orders (Gigerenzer & Todd, 1999). We examined the learning of three cue parameters defining different orders: discrimination rate (DR) (the probability that a cue points to a unique choice), validity (the probability of correct choice given that a cue discriminates), and success (the probability of correct choice). Success orderings are identical to those by expected information gain (Klayman & Ha, 1987). (...) In two experiments, participants made choices in real-world environments with objective outcome criteria. Participant ratings indicated some appropriate parameter learning when the relevant cue parameter values were highly dispersed. Rated orders of cue validity and DR were less distinct than the objective orders—learning one parameter may be biased towards success by variation in the other. Success ratings capture the variation in validity and DR as well as participants' perception of these parameters. (shrink)

Oaksford and Chater (1994) proposed to analyse the Wason selection task as an inductive instead of a deductive task. Applying Bayesian statistics, they concluded that the cards that participants tend to select are those with the highest expected information gain. Therefore, their choices seem rational from the perspective of optimal data selection. We tested a central prediction from the theory in three experiments: card selection frequencies should be sensitive to the subjective probability of occurrence for individual cards. (...) In Experiment 1, expected frequencies of the p- and the q-card were manipulated independently by concepts referring to large vs. small sets. Although the manipulation had an effect on card selection frequencies, there was only a weak correlation between the predicted and the observed patterns. In the second experiment, relative frequencies of individual cards were manipulated more directly by explicit frequency information. In addition, participants estimated probabilities for the four logical cases and of the conditional statement itself. The experimental manipulations strongly affected the probability estimates, but were completely unrelated to card selections. This result was replicated in a third experiment. We conclude that our data provide little support for optimal data selection theory. (shrink)

Information about the environment is captured in human biological systems on a variety of interacting levels – in distributions of genes, linguistic particulars, concepts, methods, theories, preferences, and overt behaviors. I investigate some of the basic principles which govern such a hierarchy by constructing a comparatively simple three-level selection model of bee foraging preferences and behaviors. The information-theoretic notion of ''''mutual information'''' is employed as a measure of efficiency in tracking a changing environment, and its appropriateness in (...) epistemological applications is discussed at some length. In particular, information accumulated in mid-level preference distributions exhibits suggestive properties for the purposes of naturalistic epistemology. It also appears that the novelty of scientific objects and representations and the rapidity of scientific change relative to genetic change need present no obstacle to the use of such models in explanations of scientific progress and the reliability of scientific judgement.

Scholars and policy makers often refer to the “information society”. And yet, it is more accurate to speak of societies, each different, some of which may qualify as information ones at different levels of maturity. Through exploration of the concepts of expectations, education and innovation, this paper explores what it means for an information society to be more or less mature than others, and the impact of this on the ongoing digital revolution.

A basic function of cognition is to detect regularities in sensory input to facilitate the prediction and recognition of future events. It has been proposed that these implicit expectations arise from an internal predictive coding model, based on knowledge acquired through processes such as statistical learning, but it is unclear how different types of statistical information affect listeners’ memory for auditory stimuli. We used a combination of behavioral and computational methods to investigate memory for non-linguistic auditory sequences. Participants repeatedly (...) heard tone sequences varying systematically in their information-theoretic properties. Expectedness ratings of tones were collected during three listening sessions, and a recognition memory test was given after each session. Information-theoretic measures of sequential predictability significantly influenced listeners’ expectedness ratings, and variations in these properties had a significant impact on memory performance. Predictable sequences yielded increasingly better memory performance with increasing exposure. Computational simulations using a probabilistic model of auditory expectation suggest that listeners dynamically formed a new, and increasingly accurate, implicit cognitive model of the information-theoretic structure of the sequences throughout the experimental session.

Following in a psychological and musicological tradition beginning with Leonard Meyer, and continuing through David Huron, we present a functional, cognitive account of the phenomenon of expectation in music, grounded in computational, probabilistic modeling. We summarize a range of evidence for this approach, from psychology, neuroscience, musicology, linguistics, and creativity studies, and argue that simulating expectation is an important part of understanding a broad range of human faculties, in music and beyond.

Discovering the meaning of novel communicative cues is challenging and amounts to navigating an unbounded hypothesis space. Several theories posit that this problem can be simplified by relying on positive expectations about the cognitive utility of communicated information. These theories imply that learners should assume that novel communicative cues tend to have low processing costs and high cognitive benefits. We tested this hypothesis in three studies in which toddlers (N = 90) searched for a reward hidden in one of (...) several containers. In all studies, an adult communicated the reward's location with an unfamiliar and ambiguous cue. We manipulated the processing costs (operationalized as inferential chain length) and cognitive benefits (operationalized as informativeness) of the possible interpretations of the cues. Toddlers processing of novel communicative cues were guided by expectations of low processing costs (Study 1) and high cognitive benefits (Studies 2 and 3). More specifically, toddlers treated novel cues as if they were easy to process, informative, and accurate, even when provided with repeated evidence to the contrary. These results indicate that, from toddlerhood onward, expectations of cognitive utility shape the processing of novel communicative cues. These data also reveal that toddlers, who are in the process of learning the language and communicative conventions of people around them, exert a pressure favoring cognitive efficiency in communicative systems.

BackgroundLack of proper understanding on the part of researchers about public understanding of research and informed consent will increase the potential for malpractice. As a part of a larger study on ethics and informed consent in Sri Lanka, this study aimed to ascertain the level of understanding of 'research' by exploring the views of the public and professionals.MethodsConvenience sampling and snow ball technique were used for recruitment with an emphasis on balanced age and gender representation, diverse educational, socio-cultural and professional (...) backgrounds, and previous research experience, either as researchers or participants. Content analysis of the data was carried out.Results66 persons (37 males, 29 females) participated. Although fundamentally a qualitative study, themes were also quantitatively analysed for informative results. Most participants thought that the word 'research' meant searching, looking, inquiring while some others thought it meant gathering information, gaining knowledge and learning.A third of participants did not offer an alternative word for research. Others suggested the words survey, exploration, search, experiment, discovery, invention and study as being synonymous. Doctors, health professionals, health institutions, scientists, professionals, businessmen, pharmaceutical companies, students, teachers were identified as people who conduct research.Participants indicated that crucial information on deciding to participate in research included objectives of the research, project importance and relevance, potential benefits to individuals and society, credibility & legitimacy of researchers, what is expected of participant, reason for selection, expected outcome, confidentiality and ability to withdraw at any time. A majority (89%) expressed their willingness to participate in future research.ConclusionsThe results show that with or without prior experience in research, participants in this study had a reasonable understanding of research. The findings show that a decision about taking part in research is dependent on knowledge, education and also on social networks.The results demonstrate that the majority were supportive of health research and believe that research is beneficial to the welfare of society.

What is considered to be fair depends on context-dependent expectations. Using a modified version of the Ultimatum Game, we demonstrate that both fair behavior and perceptions of fairness depend upon beliefs about what one ought to do in a situation—that is, upon normative expectations. We manipulate such expectations by creating informational asymmetries about the offer choices available to the Proposer, and find that behavior varies accordingly. Proposers and Responders show a remarkable degree of agreement in their beliefs about which choices (...) are considered fair. We discuss how these results fit into a theory of social norms.

Some decisions result in cognitive consequences such as information gained and information lost. The focus of this study, however, is decisions with consequences that are partly or completely noncognitive. These decisions are typically referred to as ‘real-life decisions’. According to a common complaint, the challenges of real-life decision making cannot be met by decision theory. This complaint has at least two principal motives. One is the maximizing objection that to require agents to determine the optimal act under real-world (...) constraints is unrealistic. The other is the precision objection that the numeric requirements for applying decision theory are overly demanding for real-life decisions. Responses to both objections are aired in the History section of this chapter. The maximizing objection is addressed with reference to work by Weirich and Pollock, while the precision objection is countered via a proposal by Kyburg and another by Gärdenfors and Sahlin. However, the Current Research section urges a different response to the precision objection by introducing a comparative version of decision theory. Drawing on Chu and Halpern’s notion of generalized expected utility, this version of decision theory permits many choices to be based on merely comparative plausibilities and utilities. Finally, the Further Research section undertakes an open-ended exploration of three of the assumptions upon which this form of decision theory (and many others) is based: transitivity, independence, and plausibilistic decision rules.

Background Obtaining informed consent in the clinical setting is an important yet challenging aspect of providing safe and collaborative care to patients. While the medical profession has defined best practices for obtaining informed consent, it is unclear whether these standards meet the expressed needs of patients, their families as well as healthcare providers. The authors sought to address this gap by comparing the responses of these three groups with a standardised informed consent paradigm. Methods Piloting a web-based ‘reverse’ simulation paradigm, (...) participants viewed a video showing a standardised doctor engaging in an informed consent discussion. The scenario depicted a simulated patient with psychotic symptoms who is prescribed an atypical antipsychotic medication. 107 participants accessed the simulation online and completed a web-based debriefing survey. Results Survey responses from patients, family members and healthcare providers indicated disparities in information retention, perception of the doctor's performance and priorities for required elements of the consent process. Conclusions To enhance existing informed consent best practices, steps should be taken to improve patient retention of critical information. Adverse events should be described in the short-term and long-term along with preventative measures, and alternative psychosocial and pharmacological treatment options should be reviewed. Information about treatment should include when the medication takes therapeutic effect and how to safely maintain the treatment. The reverse simulation design is a model that can discern gaps in clinical practice, which can be used to improve patient care. (shrink)

Especially in recent works, Raymond Geuss has expressed an unabashedly bleak view of the practice of philosophy and what we can expect to gain from it. In his latest collection of essays, A World Without Why, Geuss continues to write in this vein. Although he characteristically addresses an impressive variety of topics, the book is held together by a general engagement with the question of authority and by Geuss’s ongoing effort to philosophize outside the bounds of contemporary philosophy. Indeed, (...) one of the forms of authority with which he most takes issue is that of philosophy itself. Nonetheless, Geuss has a favorite cast of philosophers who he frequently enlists in his unique brand of philosophically informed... (shrink)

Parametric cognitive models are increasingly popular tools for analyzing data obtained from psychological experiments. One of the main goals of such models is to formalize psychological theories using parameters that represent distinct psychological processes. We argue that systematic quantitative reviews of parameter estimates can make an important contribution to robust and cumulative cognitive modeling. Parameter reviews can benefit model development and model assessment by providing valuable information about the expected parameter space, and can facilitate the more efficient design (...) of experiments. Importantly, parameter reviews provide crucial—if not indispensable—information for the specification of informative prior distributions in Bayesian cognitive modeling. From the Bayesian perspective, prior distributions are an integral part of a model, reflecting cumulative theoretical knowledge about plausible values of the model's parameters (Lee,2018). In this paper we illustrate how systematic parameter reviews can be implemented to generate informed prior distributions for the Diffusion Decision Model (DDM; Ratcliff and McKoon,2008), the most widely used model of speeded decision making. We surveyed the published literature on empirical applications of the DDM, extracted the reported parameter estimates, and synthesized this information in the form of prior distributions. Our parameter review establishes a comprehensive reference resource for plausible DDM parameter values in various experimental paradigms that can guide future applications of the model. Based on the challenges we faced during the parameter review, we formulate a set of general and DDM-specific suggestions aiming to increase reproducibility and the information gained from the review process.
