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.

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.

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)
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)
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.
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)
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)
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.

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.
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)
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.

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.
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.
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.

: 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.
A worldwidemental health crisis is expected, as millions worldwide fear death and disease while being forced into repeated isolation. Thus, there is a need for new proactive approaches to improve mental resilience and prevent mental health conditions. Since the 1990s, art has emerged as an alternative mental health therapy in the United States and Europe, becoming part of the social care agenda. This article focuses on how visual esthetic experiences can create similar patterns of neuronal activity as those observed when (...) the reward system is activated. The activation of the reward structures could have a stress buffering effect, given the interdependence observed between the reward and stress systems. Therefore, could visual esthetic experiences stimulate mental resilience? And if this were the case, could art-based interventions be offered for mental health in the context of COVID-19 and beyond?

Neither the range of potential results from genomic research that might be returned to participants nor future uses of stored data and biospecimens can be fully predicted at the outset of a study. Informed consent procedures require clear explanations about how and by whom decisions are made and what principles and criteria apply. To ensure trustworthy research governance, there is also a need for empirical studies incorporating public input to evaluate and strengthen these processes.
Following press disclosures in 1993 that U.S. government agencies had been using human subjects in tests and trials involving radioactive isotopes since the mid-1940s, a major national initiative to locate and declassify records concerning these tests was initiated. The U.S. Department of Energy, which led the declassification effort, pledged that a new “culture of openness” would attend the management of classified documents in the future. Following the attacks on the United States in September 2001, this momentum was reversed. Declassification initiatives (...) were delayed or terminated, and a significant portion of the many thousands of records about “human radiation experiments” during the 1940s and 1950s were removed from both online access, which had been in place since the mid-1990s, and from the public domain altogether.

GraphicalThe need to encourage individuals as active change agents for sustainability transitions has led researchers across disciplines to conceptualize over 70 constructs to assess relevant dispositions to environmental protection and green consumption behaviors. The generated knowledge is, however, fragmented by an unconsolidated set of constructs developed within parallel literature streams. We, hence, use an integrative review method to capture conceptual and operational similarities and distinctiveness of constructs across disciplines in the literature, attempting to unify the knowledge base. Thereby, we identify (...) 34 conceptually distinct constructs relevant for the thematic synthesis on individual-level constructs framing contributions to environmental measures and issues. We followingly propose a taxonomy, systemizing constructs based on their concept type and contextual scope of the environmental challenge addressed. We capture these dimensions in critically assessing relevant and salient conceptual and operational features. We thus create a consolidated picture of extant constructs capturing individual-level environmental sustainability by which we intend a three-fold contribution to the interdisciplinary field. First, the taxonomy and guiding framework for the choice of constructs should assist substantive researchers in identifying appropriate constructs of interest. Second, the systematic integration of similar concepts available in parallel literature streams should assist future endeavors aiming at integrating substantive findings with regard to antecedents, consequences, and other relevant variables. Finally, the taxonomy revealed that conceptualizations mainly scatter around specific combinations of types and scopes while others remain unaddressed. Based on our critical assessment of the relevant features and resulting taxonomy, we identify avenues for future research dedicated to enhancing conceptual rigor and measurement quality in the field and introducing concepts addressing missing but potentially valuable combinations of types and scopes. We conclude that researchers engaging in the proposed avenues with conceptual, methodological, or empirical contributions should consider four critical aspects to advance knowledge accumulation and prevent fragmentation in the interdisciplinary field. We thereby hope to pave the way for a collective, interdisciplinary knowledge base of concepts used to describe and assess individual’s pro-environmental dispositions and practices of green consumption.
