We present a novel way of accounting for similarity judgments. Our approach posits that similarity stems from three main sources—familiarity, priming, and inherent perceptual likeness. Here, we explore each of these constructs and demonstrate their individual and combined effectiveness in explaining similarity judgments. Using these three measures, our account of similarity explains ratings of simple, color-based perceptual stimuli that display asymmetry effects, as well as more complicated perceptual stimuli with structural properties; more traditional approaches to similarity solve one or the (...) other and have difficulty accounting for both. Overall, our work demonstrates the importance of each of these components of similarity in explaining similarity judgments, both individually and together, and suggests important implications for other similarity approaches.

We describe a new approach for developing and validating cognitive process models. In our methodology, graphical models (specifically, hidden Markov models) are developed both from human empirical data on a task and synthetic data traces generated by a cognitive process model of human behavior on the task. Differences between the two graphical models can then be used to drive model refinement. We show that iteratively using this methodology can unveil substantive and nuanced imperfections of cognitive process models that can then (...) be addressed to increase their fidelity to empirical data.

Associative learning is an essential feature of human cognition, accounting for the influence of priming and interference effects on memory recall. Here, we extend our account of associative learning that learns asymmetric item-to-item associations over time via experience by including link maturation to balance associations between longer-term stability while still accounting for short-term variability. This account, combined with an existing account of activation strengthening and decay, predicts both human response times and error rates for the fan effect for both target (...) and foil stimuli.

Consumption--the flow of physical materials in human lives--is an important ethical issue. Be it fair trade coffee or foreign oil, North Americans' consumption choices affect the well-being of humans around the globe, in addition to impacting the natural world and consumers themselves. In this book, Laura Hartman seeks to formulate a coherent Christian ethic of consumption.
Data documenting poor understanding among research participants and real-time efforts to assess comprehension in large-scale studies are focusing new attention on informed consent comprehension. Within the context of biobanking consent, we previously convened a multidisciplinary panel to reach consensus about what information must be understood for a prospective participant’s consent to be considered valid. Subsequently, we presented them with data from another study showing that many U.S. adults would fail to comprehend the information the panel had deemed essential. When asked (...) to evaluate the importance of the information again, panelists’ opinions shifted dramatically in the direction of requiring that less information be understood. Follow-up interviews indicated significant uncertainty about defining a threshold of understanding and what should happen when prospective participants are unable to grasp key information. These findings have important implications for urgently needed discussion of whether... (shrink)
This commentary questions the target article’s claim that enactivism and representationalism, even in an allegedly weak form, are compatible. We argue that, for a viable enactivism, it is the notion of contentless interaction that must be turned to in order to account for basic cognition, including basic color perception. Enactivism so construed can provide all the benefits the authors want: it can question exaggerated forms of objectivism, without incurring the costs that holding on to contentful representation as a naturalistically unexplained (...) ingredient in basic cognition implies.

Recruiting research participants based on genetic information generated about them in a prior study is a potentially powerful way to study the functional significance of human genetic variation, but it also presents ethical challenges. To inform policy development on this issue, we conducted a survey of U.S. institutional review board chairs concerning the acceptability of recontacting genetic research participants about additional research and their views on the disclosure of individual genetic results as part of recruitment. Our findings suggest there is (...) unlikely to be a “one-size-fits-all” solution, but rather several ethically acceptable approaches to genotype-driven recruitment, depending on context. Disclosures made during the consent process for the original study and the clinical validity of the results are key considerations. Researchers must be prepared to communicate and answer questions in clear lay language about what is known and not known regarding the role of genetics in their proposed area of research. (shrink)
Ecological restoration and native landscaping are increasing, particularly in the American Midwest, where they form part of the area's history and culture of conservation. But practitioners rarely pause to ask philosophical questions related to categories of native and invasive or human control and harmony with nature. This article brings philosophy into conversation with practice, using members of Wild Ones Native Landscaping, a non-profit headquartered in Neenah, WI, as a case study. Philosophers and ethicists who are studying Ecological Restoration and Native (...) Landscaping can learn valuable lessons - in practicality, aesthetics and flexibility - from practitioners such as the Wild Ones. (shrink)
In qualitative interviews with a diverse group of experts, the vast majority believed unregulated researchers should seek out independent oversight. Reasons included the need for objectivity, protecting app users from research risks, and consistency in standards for the ethical conduct of research. Concerns included burdening minimal risk research and limitations in current systems of oversight. Literature and analysis supports the use of IRBs even when not required by regulations, and the need for evidence-based improvements in IRB processes.
Health policymakers employ utility measures to inform resource allocation decisions. They often rely on a conceptual tool called the quality-adjusted life year that discounts the value of years lived in a state of disability relative to years lived in full health. A representative sample of the general public is asked to place values on hypothetical health states as part of a standard gamble or time trade-off task. Policymakers use the resulting values to calculate the number of QALYs gained through particular (...) interventions. Utilitarian reasoning mandates that policymakers maximize QALYs gained per unit cost.Although many scholars have explored the problems of distributive justice that arise from this system... (shrink)
Climate engineering is subject to the “playing God” critique, which charges that humans should not undertake to control nature in ways that seem to overstep the proper scope of human agency. This argument is easily discredited, and in fact the opposite—that we should “play God”—may be equally valid in some circumstances. To revive the playing God critique, I argue that it functions not on a logical but on a symbolic and emotional level to highlight nostalgia for functional dualisms in the (...) face of the bewildering problem of climate change. It also raises significant questions about the virtue of those who might engineer the climate. These two concerns point to questions about the proper role of human agency. I use the scholarship of Aldo Leopold and H. Richard Niebuhr to argue for a model of human agency based on contextual awareness and responsive, communal responsibility. I conclude with some implications of this view for decision-makers engaging the topic of climate engineering. (shrink)
For the last eighteen months, I have worked with a group of disability and health policy researchers. I began this interview-based project trying to learn how these researchers’ disability identities shaped their work. How did their disability standpoint contribute to the liberatory nature of their research? I found that the disability standpoint of these researchers was in fact hard-won and grew not just out of their own disability experiences but out of their connections with the larger disability community. These connections, (...) for the most part, helped researchers come to “claim crip,” and that later influenced their research. (shrink)
Feminist criticism of health care and ofbioethics has become increasingly rich andsophisticated in the last years of thetwentieth century. Nonetheless, this body ofwork remains quite marginalized. I believe thatthere are (at least) two reasons for this.First, many people are still confused aboutfeminism. Second, many people are unconvincedthat significant sexism still exists and aretherefore unreceptive to arguments that itshould be remedied if there is no largerbenefit. In this essay I argue for a thin,``core'' conception of feminism that is easy tounderstand and (...) difficult to reject. Corefeminism would render debate within feminismmore fruitful, clear the way for appropriaterecognition of differences among women andtheir circumstances, provide intellectuallycompelling reasons for current non-feminists toadopt a feminist outlook, and facilitatemutually beneficial cooperation betweenfeminism and other progressive socialmovements. This conception of feminism alsomakes it clear that feminism is part of alarger egalitarian moral and political agenda,and adopting it would help bioethics focus onthe most urgent moral priorities. In addition,integrating core feminism into bioethics wouldopen a gateway to the more speculative parts offeminist work where a wealth of creativethinking is occurring. Engaging with thisfeminist work would challenge and strengthenmainstream approaches; it should also motivatemainstream bioethicists to explore othercurrently marginalized parts of bioethics. (shrink)
The informed consent process for genetic testing does not commonly address preferences regarding disclosure of results in the event of the patient's death. Adults being tested for familial colorectal cancer were asked whether they want their exome sequencing results disclosed to another person in the event of their death prior to receiving the results. Of 78 participants, 92% designated an individual and 8% declined to. Further research will help refine practices for informed consent.
This article draws on in-depth case studies of 61 women and men of diverse sexual identities to show how gender, while apparently diminishing in significance, continues to shape interpretations and experiences of virginity loss in complex ways. Although women and men tended to assign different meanings to virginity, those who shared an interpretation reported similar virginity-loss encounters. Each interpretation of virginity—as a gift, stigma, or process—featured unequal roles for virgin and partner, which interacted with gender differences in power to produce (...) interpretation-specific patterns of gender subordination, only one of which consistently gave men power over women.

An audiovisual correspondence (AVC) refers to an observer’s seemingly arbitrary yet consistent matching of sensory features across the two modalities; for example, between an auditory pitch and visual size. Research on AVCs has frequently used a speeded classification procedure in which participants are asked to rapidly classify an image when it is either accompanied by a congruent or an incongruent sound (or vice versa). When, as is typically the case, classification is faster in the presence of a congruent stimulus, researchers (...) have inferred that the AVC is automatic and bottom-up. Such an inference is incomplete because the procedure does not show that the AVC is not subject to top-down influences. To remedy this problem, we devised a procedure that allows us to assess the degree of “bottom-up-ness” and “top-down-ness” in the processing of an AVC. We did this in studies of AVCs between pitch and five visual features: size, height, spatial frequency, brightness, and angularity. We find that all the AVCs we studied involve both bottom-up and top-down processing, thus undermining the prevalent generalization that AVCs are automatic. (shrink)
I examine the dynamics of measure development using two case studies: temperature, and health-related quality of life. I argue, following Bas van Fraassen and Leah McClimans that in each case these dynamics have a hermeneutic structure. Measure development is plagued by epistemic circularity, as is the task of interpreting a text, and similar strategies can be used in both measure development and hermeneutics to overcome that circularity. I show that Hans Georg Gadamer’s philosophical hermeneutics in particular are an effective lens (...) through which to examine the development of the temperature standard as described by Hasok Chang. Despite similar grounding in hermeneutics, I note an important difference between measure development for temperature and for health-related quality of life. Namely, while the meaning of temperature can be standardized, the meaning of health-related quality of life cannot. This standardization of meaning for the temperature concept represents a limit to the analogy with hermeneutics. Finally, I argue that the indeterminacy we find in health-related quality of life measurement is a result not only of analogy with the hermeneutic task, but of full-fledged participation in it.

We surveyed IRB chairs' perspectives on offering individual genetic research results to participants and families, including family members of deceased participants, and the IRB's role in addressing these issues. Given a particular hypothetical scenario, respondents favored offering results to participants but not family members, giving choices at the time of initial consent, and honoring elicited choices. They felt IRBs should have authority regarding the process issues, but a more limited role in medical and scientific issues.
: In APo II 3-7 Aristotle discusses a series of difficulties concerning definition, deduction, and demonstration. In this paper I focus on two interrelated but distinct questions: firstly, what are exactly the difficulties emerging from or alluded to in the discussion in II 3-7; secondly, whether and in what sense the discussion in II 3-7 can be considered an aporetic discussion with a specific role to play in the development of the argument in APo II.
Despite this virtue's history as an instrument of women's oppression, modesty, at its most basic, means voluntary restraint of one's power, undertaken for the sake of others. It is a mechanism that modifies unequal power relationships and encourages greater compassion and fairness. I use a Christian perspective with influences from Jewish and Muslim sources to examine modesty. The modest person, I argue, must be in relationship with others, must be honestly aware of her impacts on others, must be sensitive to (...) those impacts, compassionate toward others, and willing to hold back for others' sakes. Moreover, modesty is not only a virtue that pertains to sexuality and clothing, but it also can promote virtuous environmental behavior, particularly as it leads to awareness of, and sensitivity to, the effects of everyday behaviors on vulnerable others.
