Accessing semantic knowledge in dementia: evidence from a word definition task

We examine production of word definitions by people with probable Alzheimer's disease (pAD). In the first experiment, healthy young adults defined concrete, imageable nouns to provide a baseline of definitional ability. Analysis of these definitions identified the key defining features of each target item. In the second experiment, pAD participants and elderly controls produced definitions of the same items. In the third experiment, healthy young participants rated the adequacies of these definitions. Although as expected the pAD participants produced fewer good definitions than the other two groups, most of their responses still contained some relevant information. pAD definitions contained fewer pieces of information and the information they produced was more tangential to the primary concept than that provided by the young or elderly participants. We identify two possible explanations in semantic loss and metalinguistic impairment. We consider metalinguistic impairment to provide the more plausible explanation of pAD patients' definitional performance.     

Knowing full well: the normativity of beliefs as performances

Belief is considered a kind of performance, which attains one level of success if it is true (or accurate), a second level if competent (or adroit), and a third if true because competent (or apt). Knowledge on one level (the animal level) is apt belief. The epistemic normativity constitutive of such knowledge is thus a kind of performance normativity. A problem is posed for this account by the fact that suspension of belief seems to fall under the same sort of epistemic normativity as does belief itself, yet to suspend is of course precisely not to perform, certainly not with the aim of truth. The paper takes up this problem, and proposes a solution that distinguishes levels of performance norrmativity, including a first order where execution competence is in play, and a second order where the performer must assess the risks attendant on issuing a first-order performance. This imports a level of reflective knowledge that ascends above the animal level.

Differences from somewhere: the normativity of whiteness in bioethics in the United States

I argue that there has been inadequate attention to and questioning of the dominance and normativity of whiteness in the cultural construction of bioethics in the United States. Therefore we risk reproducing white privilege and white supremacy in its theory, method, and practices. To make my argument, I define whiteness and trace its broader social and legal history in the United States. I then begin to mark whiteness in U.S. bioethics, recasting Renee Fox's sociological marking of its American-ness as an important initial marking of its whiteness/WASP ethos. Furthermore, I consider the attempts of social scientists to highlight sociocultural diversity as a corrective in U.S. bioethics. I argue that because they fail to problematize white dominance and normativity and the white-other dualism when they describe the standpoints of African-American, Asian-American, and Native-American others, their work merely inoculates difference and creates or maintains minoritized spaces. Accordingly, the dominant white center of mainstream U.S. bioethics must be problematized and displaced for diversity research to make a difference. In conclusion, I give several examples of how we might advance the recommended endeavor of exploring our own ethnicity, class, and other social positioning and norms operating in U.S. bioethics, briefly highlighting "white talk" as one challenge.     

Kant on the normativity of taste: The role of aesthetic ideas

For Kant, the form of a subject's experience of an object provides the normative basis for an aesthetic judgement about it. In other words, if the subject's experience of an object has certain structural properties, then Kant thinks she can legitimately judge that the object is beautiful—and that it is beautiful for everyone. My goal in this paper is to provide a new account of how this ‘subjective universalism’ is supposed to work. In doing so, I appeal to Kant's notions of an aesthetic idea and an aesthetic attribute, and the connection that Kant makes between an object's expression of rational and the normativity of aesthetic judgements about it.     

The nature and normativity of anger types: A response to critics

My commentators have brought a set of claims and questions to bear on my analytical distinctions and normative arguments. Alice MacLachlan is interested in the relationship between Lordean rage and the other, more negative anger types that I describe, as well as the limits of the anger of rage renegades. Lidal Dror wonders if we should have Lordean rage, to what extent my account of resssentiment rage is in fact Lordean, and whether it is enough to only experience Lordean rage. And Nic Bommarito wonders if my other anger types could be good in certain ways and if there are other “Lordean emotions.” So, in my replies, I will address each of these in turn. And I end with a brief note about love and Lordean rage.     

Framing gender differences: Linguistic normativity affects perceptions of power and gender stereotypes

When unknown groups and equal status groups are compared by contrasting one group (“the effect to be explained”) against another (“the linguistic norm”), the group positioned as the norm is sometimes perceived as more powerful, more agentic, and as less communal. Such perceptions may contribute to status‐linked stereotypes, as group differences are spontaneously described by positioning higher‐status groups as the linguistic norm. Here, 103 participants considered gender differences in status to be larger and more legitimate and applied gender stereotypes more readily upon reading about gender differences in leadership that were framed around a male rather than a female linguistic norm. These effects did not generalize to 113 participants who read about gender differences in leisure time preferences framed around either norm. Jointly, these results suggest that the effects of linguistic framing on perceived group status and power and on group stereotypes generalize to domains where there are real differences in status, and contexts in which higher‐status groups are the default standard for comparison.

Improving the quality of medical care: the normativity of evidence-based performance standards

Poor quality medical care is sometimes attributed to physicians?? unwillingness to act on evidence about what works best. Evidence-based performance standards (EBPSs) are one response to this problem, and they are increasingly employed by health care regulators and payers. Evidence in this instance is judged according to the precepts of evidence-based medicine (EBM); it is probabilistic, and the randomized controlled trial (RCT) is the gold standard. This means that EBPSs suffer all the infirmities of EBM generally??well rehearsed problems with the external validity of research findings as well as the inferential leap from study results in the aggregate to individual patient care. These theoretical weaknesses promise to have a practical impact on the care of patients. To avoid this, EBPSs should be understood as guidelines indicative of average effectiveness rather than standards to be applied in every case.

The effect of prayer on physical health: Experimental evidence

There has been enough published scientific work on the direct effects of prayer upon physical health in the past thirty years to merit review. While experimental evidence has yet to reveal large direct effects of prayer on physical health, the effects which have been found are notable and encourage further study. In this article the authors review the major studies, discuss problems in their interpretation, and suggest considerations for future experimental study of prayer.     

The sources of normativity: young children's awareness of the normative structure of games

In two studies, the authors investigated 2- and 3-year-old children's awareness of the normative structure of conventional games. In the target conditions, an experimenter showed a child how to play a simple rule game. After the child and the experimenter had played for a while, a puppet came (controlled by a 2nd experimenter), asked to join in, and then performed an action that constituted a mistake in the game. In control conditions, the puppet performed the exact same action as in the experimental conditions, but the context was different such that this act did not constitute a mistake. Children's normative responses to the puppet's acts (e.g., protest, critique, or teaching) were scored. Both age groups performed more normative responses in the target than in the control conditions, but the 3-year-olds did so on a more explicit level. These studies demonstrate in a particularly strong way that even very young children have some grasp of the normative structure of conventional activities.     

On the spatiotemporal extensiveness of sense-making: ultrafast cognition and the historicity of normativity

The enactive approach conceives of cognition as acts of sense-making. A requirement of sense-making is adaptivity, i.e., the agent’s capacity to actively monitor and regulate its own trajectories with respect to its viability constraints. However, there are examples of sense-making, known as ultrafast cognition, that occur faster than the time physiologically required for the organism to centrally monitor and regulate movements, for example, via long-range neural feedback mechanisms. These examples open a clarificatory challenge for the enactive approach with respect to how to operationalize monitoring and regulation, and with respect to the temporal scale of sense-making, which has traditionally been limited to the here-and-now in accordance with the axiom of structural determinism. We explore possible responses to this challenge and suggest that this axiom should be explicitly rejected, in particular, we suggest that adaptivity is a property of organism–environment interactions over a time span that includes both present and past conditions. Ultrafast performances are thus no longer a challenge for the enactive approach, because the constitutive basis of their normativity is spatiotemporally extensive. This is in agreement with recent developments in different varieties of enactivism, which all converge toward assigning a constitutive role to an agent’s history of interactions.

     

Conceptualizations of respect: qualitative and quantitative evidence of four (five) themes

Respect is a term used frequently in the vernacular and psychological literature. However, frequency of use has not yielded a coherent body of psychological research on the topic, perhaps because of its elusive and contextual nature. Examining the divergent literature on respect yields 4 general themes in how it is conceptualized: (a) social rules, (b) equality, (c) caring, and (d) social power. In this study, the author used qualitative and quantitative assessment to explore the soundness of these themes. The 4 themes emerged in each of the different methods, and there was evidence of convergence of the themes across methods. A 5th unexpected theme, personal attributes, was revealed in the qualitative measures. This study provides an empirical foundation for acknowledging the complexity and potential importance of respect. Understanding the thematic variability in how respect is conceptualized will improve research, theory, and application.
