Cochlear implants electrically stimulate surviving auditory neurons in the cochlea to provide severely or profoundly deaf people with access to hearing. Signal processing strategies derive frequency-specific information from the acoustic signal and code amplitude changes in frequency bands onto amplitude changes of current pulses emitted by the tonotopically arranged intracochlear electrodes. This article first describes how parameters of the electrical stimulation influence the loudness evoked and then summarizes two different phenomenological models developed by McKay and colleagues that have been (...) used to explain psychophysical effects of stimulus parameters on loudness, detection, and modulation detection. The Temporal Model is applied to single-electrode stimuli and integrates cochlear neural excitation using a central temporal integration window analogous to that used in models of normal hearing. Perceptual decisions are made using decision criteria applied to the output of the integrator. By fitting the model parameters to a variety of psychophysical data, inferences can be made about how electrical stimulus parameters influence neural excitation in the cochlea. The Detailed Model is applied to multi-electrode stimuli, and includes effects of electrode interaction at a cochlear level and a transform between integrated excitation and specific loudness. The Practical Method of loudness estimation is a simplification of the Detailed Model and can be used to estimate the relative loudness of any multi-electrode pulsatile stimuli without the need to model excitation at the cochlear level. Clinical applications of these models to novel sound processing strategies are described. (shrink)

In his 2012 book Jussim argues that the self-fulfilling prophecy and expectancy effects of descriptive stereotypes are not potent shapers of social reality. However, his conclusion that descriptive stereotypesper sedo not shape social reality is premature and overly reductionist. We review evidence that suggests descriptive stereotypes do have a substantial influence on social reality, by virtue of their influence on collective action.

Inducing religious thoughts increases prosocial behavior among strangers in anonymous contexts. These effects can be explained both by behavioral priming processes as well as by reputational mechanisms. We examine whether belief in moralizing supernatural agents supplies a case for what McKay & Dennett (M&D) call evolved misbelief, concluding that they might be more persuasively seen as an example of culturally evolved misbelief.

We review scholarship that examines relationships - and distinctions - between religion and delusion. We begin by outlining and endorsing the position that both involve belief. Next, we present the prevailing psychiatric view that religious beliefs are not delusional if they are culturally accepted. While this cultural exemption has controversial implications, we argue it is clinically valuable and consistent with a growing awareness of the social - as opposed to purely epistemic - function of belief formation. Finally, we review research (...) on continuities between religious and delusional cognition, which reveals that religious content is quite common in delusions and which provides tentative evidence for a positive relationship between religious belief and delusion-like belief in the general population.

Repetitive thinking predicts and maintains depression and anxiety, yet the role of RT in the perinatal context has been under-researched. Further, the content and themes that emerge during RT in the perinatal period have been minimally investigated. We recruited an online community sample of women who had their first baby within the past 12 months. Participants completed a battery of self-report questionnaires which included four open-ended questions about the content of their RT. Responses to the latter were analyzed using an (...) inductive thematic analysis approach. Participants reported RT about a range of unexpected emotional responses to becoming a new mother, impact on their sleep and cognitive functioning, as well as the impact on their identity, sense of self, lifestyle, achievements, and ability to function. RT was commonly experienced in first-time mothers, and the themes that emerged conveyed an overall sense of discrepancy between expectations and reality, as well as adjustment to profound change. By providing insight into the content of RT in new mothers, the findings of our study have scope to inform the content of interventions that seek to prevent and treat postnatal mental health problems, particularly those which target key psychological processes such as RT.

In this introduction to part 4 of the Common Knowledge symposium “Peace by Other Means,” the journal's editor assesses the argument made by Peace, the spokesperson of Erasmus in his Querela Pacis, that the desire to impute and avenge wrongs against oneself is insatiable and at the root of both individual and social enmities. He notes that, in a symposium about how to resolve and prevent enmity, most contributions have to date expressed caveats about how justice and truth must take (...) precedence over peace, how recovery from ill treatment may be impossible, how quietism is not a moral option, and how realism demands a national policy and a personal strategy of, at best, contingent forgiveness. He concedes that the attitudes of those opposed to quietism are healthy but suggests that there may be goods worthier than health of human devotion. This essay concludes that the main differences between what it terms “judgmental” and “irenic” regimes are disagreements over anthropology and metaphysics. The presumptions that truths are objectively knowable and that human beings are moral and rational agents characterize judgmental regimes; irenic regimes are characterized by disillusionment with those assumptions.

Boyer & Petersen argue that folk-economic beliefs are widespread – shaped by evolved cognitive systems – and they offer exemplar beliefs to illustrate their thesis. In this commentary, we highlight evidence of substantial variation in one of these exemplars: beliefs about immigration. Contra claims by B&P, we argue that the balance of this evidence suggests the “folk” may actually holdpositivebeliefs about the economic impact of immigration.

Competent patients have considerable legal authority to control life‐and‐death care. They may refuse medical life support, including medically delivered food and fluids. Even when they are not in need of any life‐saving care, they may expedite death by refusing food and water by mouth—voluntarily stopping eating and drinking, or VSED. Neither right is limited to terminal illness. In addition, in four U.S. states, competent patients, if terminally ill, may obtain lethal drugs for aid‐in‐dying.For people who have dementia and are no (...) longer competent, however, control over the end of life is much less extensive. They may have written a clear advance directive for refusing life‐saving care in specified circumstances yet subsequently find themselves living for years in severe dementia with no need for life‐saving care that could be refused. Chronic progressive dementia is not itself life threatening until its very final stage. Even in jurisdictions that permit active aid‐in‐dying, individuals with advanced dementia are not eligible; they lack the required current competence, and they are seldom deemed terminally ill. As for the right to VSED, its very name—voluntarily stopping eating and drinking—is seen as excluding noncompetent persons.One option for ensuring that one does not live years in severe dementia is to use advance directives to withhold food and water by mouth. The driving element behind VSED is that forcing people to ingest food is as objectionable an intrusion on bodily integrity, privacy, and liberty as imposing unwanted medical treatment. Thus, if incompetent people do not lose their rights to refuse life‐saving treatment, and if people when competent have just as strong a right to VSED as they do to refuse life‐saving treatment, then people do not lose their right to VSED when incompetent either. They only have to exercise it by AD. (shrink)

Most human beliefs are acquired through communication, and so are most misbeliefs. Just like the misbeliefs discussed by McKay & Dennett (M&D), culturally transmitted misbeliefs tend to result from limitations rather than malfunctions of the mechanisms that produce them, and few if any can be argued to be adaptations. However, the mechanisms involved, the contents, and the hypothetical adaptive value tend to be specific to the cultural case.

McKay & Dennett (M&D) suggest that some positive illusions are adaptive. But there is a bidirectional link between memory and positive illusions: Biased autobiographical memories filter incoming information, and self-enhancing information is preferentially attended and used to update memory. Extending M&D's approach, I ask if certain false memories might be adaptive, defending a broad view of the psychosocial functions of remembering.

McKay & Dennett's (M&D's) description of beliefs, and misbeliefs in particular, is a commendable contribution to the literature; but we argue that referring to beliefs as adaptive or maladaptive can cause conceptual confusion. “Adaptive” is inconsistently defined in the article, which adds to confusion and renders it difficult to evaluate the claims, particularly the possibility of “adaptive misbelief.”.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Aquinas and the Infused Moral Virtues by Angela McKay KnobelThomas M. Osborne Jr.KNOBEL, Angela McKay. Aquinas and the Infused Moral Virtues. Notre Dame, Ind.: University of Notre Dame Press, 2021. 214 pp. Cloth, $65.00This book is the first substantial English monograph on Aquinas's account of the infused virtues in many years, and the most significant treatment of the issue since Gabriel Bullet, Vertus morales infuses et (...) vertus morales acquises selon Saint Thomas d'Aquin (Fribourg: Éditions Universitaires, 1958). The infused virtues are about, or they are intrinsically ordered to, the supernatural end of human beings. Aquinas was among the first to argue that the infused virtues include not only the three theological virtues of faith, hope, and charity, but also supernatural counterparts to the acquired virtues, which are proportionate to the natural end of humans. These infused moral virtues are infused with charity and lost with mortal sin. Aquinas never addressed at length the relationship between acquired [End Page 144] and infused moral virtues, and many theologians rejected Aquinas's position that there are infused moral virtues.Knobel's book has two parts. The first part of the book consists of three chapters about Aquinas's own views. Chapter 1 is on natural virtue, which can be acquired through the agent's own efforts. Knobel emphasizes the way in which this virtue is proportionate to the natural end and abilities of humans. She correctly notes that Aquinas thinks that humans can perform such virtuous acts without grace. However, since she does not distinguish between morally good acts and morally good agents, she does not adequately address Aquinas's view of how sinners without grace might possess acquired virtue. Additionally, although she correctly notes the way in which moral virtue orders the agent to the end, it is often unclear whether she is discussing the proximate end of the will (which is an object), a further end (as when someone steals to commit adultery), or the ultimate end (which is God as the object of charity or the self as an object of disordered love). For example, she writes, "[I]f an act is not sinful, it cannot be ordered to an evil end." She might be making the uncontroversial claim that good acts are made evil when directed to a bad end, but in her argument she seems to be making the stronger claim that someone with a disordered ultimate end cannot habitually order good acts to such an end.Chapter 2 is on the infused virtues. Knobel notes that for Aquinas synderesis, which is a habit of grasping first practical principles, is a seed of the natural virtues, and that faith, which grasps revealed principles, plays this role in infused virtue. She shows how infused moral virtues, which share the same matter as the acquired moral virtues, have different ends and rules than the acquired virtues. Chapter 3 concerns Aquinas's account of the relationship between the acquired and infused virtues, and in particular the infused moral virtues. Knobel draws attention to texts in which Aquinas argues that the two coexist in someone who has grace, but she states that this coexistence is contradicted in the discussion of Macrobius's fourfold division of virtue in the Summa Theologiae (I-II, q. 61, a. 5). In this article, she thinks, acquired virtue is political virtue, and a stage toward infused virtue. She does not address how Aquinas uses the term "political virtue" differently in different texts, and how the schema of four virtues in this text might be read as describing both four stages of acquired virtue and four stages of infused virtue. Knobel supports her view—that those with grace lack acquired virtue—by claiming that Aquinas consistently states that there is no acquired virtue in heaven. This view only tenuously (at best) supports her point that acquired virtue does not exist in this life among those in a state of grace. Moreover, Aquinas seems to suggest that acquired virtue persists in the next life in ST I-II, q. 67, a. 1-2.The second part of the book is a criticism of contemporary interpretations of Aquinas, and an exposition of...

The patient-doctor relationship has recently come under intense scrutiny, resulting in a re-evaluation of the basis of that relationship. The papers by Glannon and Ross, and McKay seek to identify the sources of authority in the patient-doctor relationship by evaluating it in terms of the concept of altruism. In this paper I argue that the analysis of Glannon and Ross, and of McKay is unnecessary and that the analysis offered by the latter is also flawed. I do acknowledge, (...) however, that Glannon and Ross's description of doctors' responsibilities and patients' roles has much to commend it. (shrink)

We propose another positive illusion that fits with McKay & Dennett's (M&D's) criteria for adaptive misbeliefs. This illusion is pervasive in adult reasoning but we focus on its prevalence in children's developing theories. It is a strongly held conviction arising from normal functioning of the doxastic system that confers adaptive advantage on the individual.

Rupturing along part the Hope Fault during a large earthquake in 1888, North Canterbury region, South Island of New Zealand, caused fence lines that crossed the fault to be laterally displaced by 1.5–2.6 m. The offset fence lines were documented (photographed, mapped, and published on) by the Government geologist, Alexander McKay, and forgotten. In the same year, observations of another fault line, the Awatere Fault, in the Marlborough area, South Island, led McKay to propose large-scale lateral displacement of (...) ∼ 29–33 km of geological formations along the fault, the result of cumulative movement of many earthquakes over millions of years (ca. 7 Ma). This ‘revolutionary’ idea was never published. The significance of McKay’s observations/deductions of small- and large-scale lateral displacement on faults was not fully appreciated in New Zealand until 1955 when aerial photography revealed that displacement of geomorphic features intersecting fault lines is dominantly horizontal rather than vertical. The idea of large-scale horizontal movement of the Earth’s crust, for example 483 km of lateral displacement of geological formations along the Alpine Fault in New Zealand first proposed in 1949, is now an integral part of the reigning paradigm of plate tectonics theory that explains the dynamics of movement of the Earth’s crust.

In the light of increasing public mistrust, there is an urgent need to clarify the moral status of the medical profession and of the relationship of the clinician to his/her patients. In addressing this question, I first establish the coherence, within moral philosophy generally, of the concept of supererogation . I adopt the notion of an act of “unqualified” supererogation as one that is non-derivatively good, praiseworthy, and freely undertaken for others' benefit at the risk of some cost to the (...) agent. I then argue that committing oneself to the profession of clinical medicine is an act of this kind. This is the case, not because the aim of medicine is to help patients, but because of the open ended commitment of time and the vulnerability to the consequences of failure that the clinician must accept.

To meet the luck objection to incompatibilism, philosophers such as Timothy O’Connor, Randolph Clark, and William Rowe resurrected the Reidian notion of agent causation, which implies the “Substance-Causal Thesis” (SCT): some causes are fundamentally substances, not events. I examine an objection to SCT by C. D. Broad, developed by Carl Ginet, that substances cannot cause events because substances cannot explain why events happen when they do. The objection fails as it rests on a demand for contrastive explanations of free actions. (...) However, I show that a slightly different objection succeeds in showing SCT false. (shrink)

Young and colleagues . Betwixt life and death: case studies of the Cotard delusion. In P. W. Halligan & J. C. Marshall , Method in madness: Case studies in cognitive neuropsychiatry. Mahway, NJ: Lawrence Erlbaum Associates.) have suggested that cases of the Cotard delusion result when a particular perceptual anomaly occurs in the context of an internalising attributional style. This hypothesis has not previously been tested directly. We report here an investigation of attributional style in a 24-year-old woman with Cotard (...) delusion . LU’s attributional style was assessed using the Internal, Personal and Situational Attributions Questionnaire . A new measure of causal locus: the internal, personal and situational attributions questionnaire. Personality and Individual Differences, 20, 261–264.). LU showed a significantly greater proportion of internalising attributions than the control group, both overall and for negative events specifically. The results obtained thus support an association of Cotard delusion with an internalising attributional style, and are therefore consistent with the account of Young and colleagues. The potential brain basis of Cotard delusion is discussed. (shrink)

Cet article expose, à partir de deux cas, certaines difficultés de l’adoption. Il vise à montrer le décalage entre le désir des adoptants et la réalité parfois très dure qu’ils vont devoir affronter. Surtout lorsqu’il s’agit d’enfants de plus de cinq ans, porteurs d’un passé traumatique qui reste non dit. La création de liens forts se fait cependant au milieu de ce vécu difficile et, dans le meilleur des cas, les parents y jouent alors un rôle de soignants.

As the new Cell-free DNA (Cf-DNA) prenatal screening test for Down syndrome was being introduced into the UK’s fetal anomaly screening program, Down syndrome charities had an opportunity to participate. An experience of co-production where we were the minority voice then followed. This paper explores that process and our experience as a charity. Institutional and societal structures meant that it was difficult to be heard and a significant amount of bias was noted within the program. Consequently, our viewpoints were often (...) considered and then dismissed. However, at times we were listened to, and feel that there were some valuable changes made resulting from our involvement. The end product was far from reflective of all that we stand for, and there are still lessons to be learned in England about the need to place a higher value on minority voices of lived experience in a co-production exercise.

I argue that, all else being equal, theism is more probable than naturalism on the assumption that human beings are able to arrive at a body of moral knowledge that is largely accurate and complete. I put forth this thesis on grounds that, if naturalism is true, the explanation of the content of our moral intuitions terminates either in biological-evolutionary processes or in social conventions adopted for pragmatic reasons; that, if this is so, our moral intuitions were selected for their (...) utility, not their truth; and that, if our moral intuitions were so selected, they are probably false. I defend the argument against three objections: first, that the argument amounts to a generic skeptical challenge; second, that ethical naturalism explains how our moral intuitions could have been selected for their truth; and third, that there is a pre-established harmony between the utility of moral beliefs and their truth-values.

The impact of our desires and preferences upon our ordinary, everyday beliefs is well-documented [Gilovich, T. . How we know what isn’t so: The fallibility of human reason in everyday life. New York: The Free Press.]. The influence of such motivational factors on delusions, which are instances of pathological misbelief, has tended however to be neglected by certain prevailing models of delusion formation and maintenance. This paper explores a distinction between two general classes of theoretical explanation for delusions; the motivational (...) and the deficit. Motivational approaches view delusions as extreme instances of self-deception; as defensive attempts to relieve pain and distress. Deficit approaches, in contrast, view delusions as the consequence of defects in the normal functioning of belief mechanisms, underpinned by neuroanatomical or neurophysiological abnormalities. It is argued that although there are good reasons to be sceptical of motivational theories , recent experiments confirm that motives are important causal forces where delusions are concerned. It is therefore concluded that the most comprehensive account of delusions will involve a theoretical unification of both motivational and deficit approaches. (shrink)

An ethic of care acknowledges the centrality of the role of caring relationships in moral education. Care ethics requires a conception of ?care? that differs from the quotidian use of the word. In order to teach care ethics more effectively, this article discusses four interrelated ways that teachers? understandings of care differ from care ethics: (1) conflating the term of reference ?care? with its quotidian use; (2) overlooking the challenge of developing caring relationships; (3) tending toward monocultural understandings of care; (...) and (4) separating affect and intellect. Awareness of these conceptions of care supports teacher educators to teach care ethics in more meaningful and relevant ways. We explore stories and their dramatization as a medium to facilitate effective and in-depth teaching of care ethics. (shrink)

Despite the successes, and the considerable and continuing ethical disputes regarding wolf reintroduction in the United States, no clear, cogent, theoretically based ethical examination of the wolf reintroductions has yet been completed. Ecological feminist thought, particularly as articulated by Karen J. Warren, presents one way to create such an ethical assessment. Applying ecological feminist theories to wolf reintroduction also generates an intriguing instance of theoretical application in the “real world” and sheds insight on the pragmatic value of ecological feminist thought. (...) While ecofeminism does not give a definitive and decisively defensible position concerning wolf reintroduction, it does offer a repeatable framework and set of conditions by which one can assess environmental practice and policy, evidencing yet another example of the relevance of environmental ethics for the assessment of environmental policy.
