Threshold- and signal-detection-based models have dominated theorizing about recognition memory. Building upon these theoretical frameworks, we have argued for a dual-process model in which conscious recollection and familiarity contribute to memory performance. In the current paper we assessed several memory models by examining the effects of levels of processing and the number of presentations on recognition memory receiver operating characteristics . In general, when the ROCs were plotted in probability space they exhibited an inverted U shape; however, when they were (...) plotted inzspace they exhibited a U shape. An examination of the ROCs showed that the dual-process model could account for the observed ROCs, but that models based solely on either threshold or signal-detection processes failed to provide a sufficient account of the data. Furthermore, an examination of subjects' introspective reports using the remember/know procedure showed that subjects were aware of recollection and familiarity and were able to consistently report on their occurrence. The remember/know data were used to accurately predict the shapes of the ROCs, and estimates of recollection and familiarity derived from the ROC data mirrored the subjective reports of these processes.

Recollection is sometimes automatic in that details of a prior encounter with an item come to mind although those details are irrelevant to a current task. For example, when asked about the size of the type in which an item was earlier presented, one might automatically recollect the location in which it was presented. We used the process dissociation procedure to show that such noncriterial recollection can function as familiarity—its effects were independent of intended recollection.

Although death statutes permitting physicians to declare brain death are relatively uniform throughout the United States, academic debate persists over the equivalency of human death and brain death. Alan Shewmon showed that the formerly accepted integration rationale was conceptually incomplete by showing that brain-dead patients demonstrated a degree of integration. We provide a more complete rationale for the equivalency of human death and brain death by defending a deeper understanding of the organism as a whole and by using a novel (...) strategy with shared objectives to justify death determination criteria. Our OaaW account describes different types of OaaW, defining human death as the loss of status as a human OaaW. We defend human death as similar to nonhuman death in terms of wakefulness, but also distinct in terms of the sui generis properties, particularly conscious awareness. We thereby defend the equivalency of brain death and human death using a resulting neurocentric rationale. (shrink)

This study in cross-cultural hermeneutics examines the role that modern, Western philosophy has played in the interpretation of Nagarjuna's Madhyamikakarika, a second-century Indian-Buddhist text. Tuck locates a structure of distinct phases or "styles" in modern, philosophical history. These phases, Tuck shows, exhibit discontinuous interpretive biases, as well as continuity of hermeneutic intention. Discovering in each philosophical era a chaacteristic attitude towards the text--whether privilege, objectivity, or neutrality--Tuck argues that the continual reinterpretation of earlier scholarly readings is in fact at the (...) core of fruitful hermeneutic pursuit.

Jonathan Quong Ethics, 119, 507–537 has recently argued that the permissibility of killing innocent threats turns on a distinction between eliminative and opportunistic agency. When we kill bystanders we view them under the guise of opportunism by using them as mere survival tools, but when we kill threats we simply eliminate them. According to Quong, the distinction between opportunistic and eliminative agency reveals that there are two different ways of killing someone as a means to save your own life. Call (...) this the Means Distinction. In this note, I argue that although the Means Distinction seems prima facie plausible it is not a sufficient explanation for the permissibility of killing threats. My argument against the Means Distinction is two-fold. Most non-consequentialists accept that the Means Distinction carries some moral significance, but I argue that this is a mistake: we do not have any reason to believe that opportunistic killings are, in general, worse than eliminative killings. Following this, I argue that even if we accept the Means Distinction, there are threat-type scenarios in which there is no intuitive difference between killing a threat opportunistically and killing a threat eliminatively.

Sweeping denials of the story's capacity to accurately reflect the past are ever catalyzing equally misleading global affirmations. The impositionalists, such as theorist Hayden White, view historical narratives as imposing a falsifying narrative structure on the past, and conclude that narratives cannot be true. Plot-reifiers, such as Alasdair MacIntyre, David Carr, and Frederick Olafson, posit that the past is already narratively structured; historical plots are reified in order for there to be something in the world to which narrative structures can (...) correspond in being true. The antireferentialists such as JeanFrançois Lyotard and Roland Barthes deny that narrative histories even claim truth. Escaping this trilemma of theoretical interpretation involves accepting the idea that construction of a history does not entail its falsification. Historical narrative need to be allowed to function both figurally, in the sense of generating new discursive figures, and at the same time literally, in the sense of asking to be understood literally. Narratives need to be understood on their own terms, and not treated as an approximation to some foreign ideal. (shrink)

Aggleton & Brown argue that a hippocampal-anterior thalamic system supports the “recollection” of contextual information about previous events, and that a separate perirhinal-medial dorsal thalamic system supports detection of stimulus “familiarity.” Although there is a growing body of human literature that is in agreement with these claims, when recollection and familiarity have been examined in amnesics using the process dissociation or the remember/know procedures, the results do not seem to provide consistent support. We reexamine these studies and describe the results (...) of an additional experiment using a receiver operating characteristic (ROC) technique. The results of the reanalysis and the ROC experiment are consistent with Aggleton & Brown's proposal. Patients with damage to both regions exhibit severe deficits in recollection and smaller, but consistent, deficits in familiarity. (shrink)

First responders to chemical, biological, radiological, or nuclear (CBRN) events face decisions having significant human consequences. Some operational decisions are supported by standard operating procedures, yet these may not suffice for ethical decisions. Responders will be forced to weigh their options, factoring-in contextual peculiarities; they will require guidance on how they can approach novel (indeed unique) ethical problems: they need strategies for “on the spot” ethical decision making. The primary aim of this paper is to examine how first responders should (...) approach on the spot ethical decision-making amid the stress and uncertainty of a CBRN event. Drawing on the long-term professional CBRN experience of one of the authors, this paper sets out a series of practical ethical dilemmas potentially arising in the context of a large-scale chemical incident. We propose a broadly consequentialist approach to on the spot ethical decision-making, but one which incorporates ethical values and rights as “side-constraints”. (shrink)

Observing averted eye gaze results in the automatic allocation of attention to the gazed-at location. The role of the orientation of the face that produces the gaze cue was investigated. The eyes in the face could look left or right in a head-centred frame, but the face itself could be oriented 90 degrees clockwise or anticlockwise such that the eyes were gazing up or down. Significant cueing effects to targets presented to the left or right of the screen were found (...) in these head orientation conditions. This suggests that attention was directed to the side to which the eyes would have been looking towards, had the face been presented upright. This finding provides evidence that head orientation can affect gaze following, even when the head orientation alone is not a social cue. It also shows that the mechanism responsible for the allocation of attention following a gaze cue can be influenced by intrinsic object-based (i.e. head-centred) properties of the task-irrelevant cue.

Husserl's proposed method for knowing the essences of universals, which he calls “free variation,” has been widely criticized for involving viciously circular reasoning. In this paper, I review existing attempts to resolve this problem, and I argue that they all fail. I then show that extant accounts are all guilty of a common mistake: they assume that circularity is inevitable as long as the exercise of free variation presupposes the ability to identify the universal whose essence is in question, that (...) is, the ability to recognize entities as instances of it. I reject this assumption: I argue on both Husserlian and independent philosophical grounds that knowledge of a universal's essence is not required for identifying it, but only for re‐identifying it at every possible world in which it is instantiated. I then defend a reading on which free variation's purpose is to move its practitioner from non‐essentialistic knowledge of a universal's identity (its actual instantiation‐pattern) to essentialistic knowledge of its transworld identity (its instantiation‐pattern in every possible world in which it is present). And I show that such a transformation is a non‐circular progression from non‐modal to modal knowledge. (shrink)

The two authors of this paper have diametrically opposed views of the prevalence and strength of adaptation in nature. Hendry believes that adaptation can be seen almost everywhere and that evidence for it is overwhelming and ubiquitous. Gonzalez believes that adaptation is uncommon and that evidence for it is ambiguous at best. Neither author is certifiable to the knowledge of the other, leaving each to wonder where the other has his head buried. Extensive argument has revealed that each author thinks (...) his own view is amply supported by both theory and empirical evidence. Further reflection has revealed that the differences in opinion may start with the different disciplines in which we work: evolutionary ecology for Hendry and community ecology for Gonzalez. In the present paper, we each present devastating evidence supporting our own position and thus refuting that of the other. We then identify the critical differences that led to such opposing views. We close by combining our two perspectives into a common framework based on the adaptive landscape, and thereby suggest means by which to assess the prevalence and strength of adaptation. (shrink)

This paper examines the use of “literature” in research projects in Sociology and Library & Information Science and proposes that there are some limits to the programme of interdisciplinarity. The loci of considerations are found in literature review sections of published articles. “The literature” is an arbitrary term that refers to recognized and relevant collections of work according to context. Associating aspects of disciplinary work such as concepts, methods and writings, with Wes Sharrock’s ethnomethodological notion of “ownership”, affords analysis of (...) interdisciplinary research strategies. This in turn facilitates examination of how discipline or field-specific terms are put to use. This paper suggests that the use of sociological and ethnomethodological approaches within some disciplinary and interdisciplinary studies is questionable. The equivocal nature of “literature” use arises from attempts to fit “literature” to research projects, and from misunderstanding the internal logic of research app... (shrink)

This article takes a conceptual approach to an issue of pedagogical relevance—the presence of teaching and learning moments within educational environments. We suggest sources of philosophical confusions that design patterns for the classification and creation of typologies of classroom events. We identify three foundational assumptions with the way in which classroom events are analyzed: Describing a classroom event ; Devising a procedure for co-classifying events ; Repurposing decontextualized events to fit a preferred analytic model. Hitherto these assumptions have obscured the (...) phenomenal integrity of the learning environment; since the topic sought is based on critical incidents according to analysts’ interests, but not on the actual identifying details of the setting as made available by the participants. While teaching and learning moments are generic issues, in methodological terms these matters have to be explored in their details. In our article, we align ourselves with particular research approaches, namely ethnomethodology and conversation analysis, that facilitate close analysis of ‘perspicuous settings’, such as classroom interactions, through which phenomena such as teaching and learning moments are made visible as collaborative accomplishments.

Social scientists using one or another concept of process have paid little attention to underlying issues of methodology and explanation. Commonly, the concept used is a loose one. When it is not, there often are other problems, such as errors of reification and of assuming that events sometimes connected in a sequence are invariably thus connected. While it may be useful to retain the term " process" for some sequences of intelligibly connected actions and events, causal explanation must be sought (...) with respect to the events constituting processes rather than with respect to processes regarded as unitary entities.

One approach to validating simulation models is to formally compare model outputs with independent data. We consider such model validation from the point of view of Frequentist statistics. A range of estimates and tests of goodness of fit have been advanced. We review these approaches, and demonstrate that some of the tests suffer from difficulties in interpretation because they rely on the null hypothesisHypothesis that the model is similar to the observationsObservations. This reliance creates two unpleasant possibilities, namely, a model (...) could be spuriously validated when dataData are too few, or inappropriately rejected when data are too many. Finally, these tests do not allow a principled declaration of what a reasonable level of difference would be considering the purposes to which the model will be put. We consider equivalence tests, and demonstrate that they do not suffer from the previously identified shortcomings. We provide two case studies to illustrate the claims of the chapter. (shrink)

Introduction Non-consequentialists often attempt to capture a familiar, if slightly elusive, sense of moral wrongness. In particular, many non-consequentialists give a central role to the idea that there is a distinction to be made between acting wrongly and wronging someone. To explain, consider the difference between my duty not to trample sunflowers and my duty not to trample you. In the case of sunflowers, I might act wrongly in trampling them without good reason, but it does not seem that I (...) can wrong them by doing so. In juxtaposition, if I trample you it does not seem that I have merely acted wrongly, but that I have wronged you in particular because I owe it to you not to do so. Call this the Wronging Distinction.Arguably, the Wronging Distinction is important because it offers one possible way of explaining the intuitive authority of moral reasons. Deontic constraints, for example, seem to carry an unusual normative stringency insofar as they seem to be non-optional. Ted, for i .. (shrink)

Reflective journals are characterized by their expressive freedom and their intent that students explicitly connect course material to their own life experiences, emotions, beliefs, and feelings. Drawing on research on the use of reflective journals and on the reflections of students in my philosophy courses, I demonstrate how philosophy professors can use reflective journals as a tool to help their students achieve important learning outcomes. By making philosophy personal for students, reflective journals allow students to practice philosophy as a way (...) of life, achieve important metacognitive outcomes, and (drawing on constructivism in learning theory) increase their knowledge and understanding of course content.

This paper addresses the problem of ‘premature consent’. The term ‘premature consent’ denotes patient decisions that are: formulated prior to discussion with the appropriate healthcare professional ; based on information from unreliable sources ; and resolutely maintained despite the HCP having provided alternative reliable information. HCPs are not obliged to respect premature consent patients’ demands for unindicated treatments. But why? What is it that premature consent patients do or get wrong? Davis has argued that premature consent patients are incompetent and (...) misinformed. We argue that this view is not sustainable. A more plausible position asserts that premature consent threatens the integrity of the medical profession. We argue that this gives rise to a negative patient duty which premature consent patients fail to honour. We argue for a further positive duty of good faith engagement in shared decision-making. This implies willingness to potentially revise or justify one’s evaluative bases. Fundamentally, the problem with premature consent patients is that certain of their evaluative bases are not open to revision. They therefore fail in their duty to participate faithfully in the shared decision-making process. (shrink)

Biometric identification is thought to be less vulnerable to fraud and forgery than are traditional forms of identification. However biometric identification is not without vulnerabilities. In a ‘spoofing attack’ an artificial replica of an individual’s biometric trait is used to induce a system to falsely infer that individual’s presence. Techniques such as liveness-detection and multi-modality, as well as the development of new and emerging modalities, are intended to secure biometric identification systems against such threats. Unlike biometrics in general, the societal (...) and ethical issues raised by spoofing and anti-spoofing techniques have not received much attention. This paper examines these issues. (shrink)

I have admitted different kinds of power but the admission does not make it objectionable--in spite of Dr. Beardsley's point and Mr. Grünbaum's opening statement--to use the same word in order to indicate that all these kinds are under the same category--Mr. Williams' rejection of the category notwithstanding--of latent but directed tendencies or dispositions. Let my critics envisage power by analogy with, and including, the physical vector of force. i.e. as something which we represent by an arrow, to induce them (...) to reconsider Dr. Beardsley's point and to concede that the Gestalt forces of cohesion and personal dispositions belong to the category under consideration since both are directed agencies. The directedness of power--let me add with reference to Mr. Feigl's point and to one of Mr. Krikorian's questions --enables me to account for the so-called teleological situations without assuming a metaphysics of teleology. In particular, I can mention a "feed-back" mechanism in order to give an example of the transformation of directed into directing, or controlling, power. (shrink)

2. An explicit sense datum appears enframed within the present at a definite place. By contrast a tendency is to be described as an agency that bears upon something other than itself. It tends toward something. Accordingly, power is distinguished not only by its magnitude or intensity but also by directedness. And, since directedness takes the form of cross-references within the field of tension, power is a factor of integration.
