Multiple cue probability learning studies have typically focused on stationary environments. We present three experiments investigating learning in changing environments. A fine-grained analysis of the learning dynamics shows that participants were responsive to both abrupt and gradual changes in cue-outcome relations. We found no evidence that participants adapted to these types of change in qualitatively different ways. Also, in contrast to earlier claims that these tasks are learned implicitly, participants showed good insight into what they learned. By fitting formal learning (...) models, we investigated whether participants learned global functional relationships or made localized predictions from similar experienced exemplars. Both a local (the Associative Learning Model) and a global learning model (the novel Bayesian Linear Filter) fitted the data of the first two experiments. However, the results of Experiment 3, which was specifically designed to discriminate between local and global learning models, provided more support for global learning models. Finally, we present a novel model to account for the cue competition effects found in previous research and displayed by some of our participants. (shrink)

There is a diverse group of human genetic disorders affecting growth hormone action that lead to short stature. Insights into their pathophysiology can be gained by a combination of classical and molecular genetic studies.

We consider the set of jumps below a Turing degree, given by JB={x':x≤a}, with a focus on the problem: Which recursively enumerable degrees a are uniquely determined by JB? Initially, this is motivated as a strategy to solve the rigidity problem for the partial order R of r.e. degrees. Namely, we show that if every high2 r.e. degree a is determined by JB, then R cannot have a nontrivial automorphism. We then defeat the strategy—at least in the form presented—by constructing (...) pairs a0, a1 of distinct r.e. degrees such that JB=JB within any possible jump class {x:x'=c}. We give some extensions of the construction and suggest ways to salvage the attack on rigidity. (shrink)

We present a new modeling framework for recognition memory and repetition priming based on signal detection theory. We use this framework to specify and test the predictions of 4 models: (a) a single-system (SS) model, in which one continuous memory signal drives recognition and priming; (b) a multiple-systems-1 (MS1) model, in which completely independent memory signals (such as explicit and implicit memory) drive recognition and priming; (c) a multiple-systems-2 (MS2) model, in which there are also 2 memory signals, but some (...) degree of dependence is allowed between these 2 signals (and this model subsumes the SS and MS1 models as special cases); and (d) a dual-process signal detection (DPSD1) model, 1 possible extension of a dual-process theory of recognition (Yonelinas, 1994) to priming, in which a signal detection model is augmented by an independent recollection process. The predictions of the models are tested in a continuous-identification-with-recognition paradigm in both normal adults (Experiments 1–3) and amnesic individuals (using data from Conroy, Hopkins, & Squire,2005). The SS model predicted numerous results in advance. These were not predicted by the MS1 model, though could be accommodated by the more flexible MS2 model. Importantly, measures of overall model fit favored the SS model over the others. These results illustrate a new, formal approach to testing theories of explicit and implicit memory. (shrink)

Objectives—To evaluate a departmental computer system.Design—a. Direct comparison of the time taken to use a manual system with the time taken to use a computer system for lung function evaluation, loan of equipment and production of correspondence. b. Analysis of the accuracy of data capture before and after the introduction of the computer system. c. Analysis of the comparative running costs of the manual and computer systems.Setting—Within a department of respiratory medicine serving a hospital of 1323 beds.Main Outcome Measures—a. Time (...) taken to perform functions with the assistance of computerised methods, in comparison to the manual method used alone. b. Accuracy of data capture. c. Relative running costs.Results—a. The computer system was significantly faster than the manual system for lung function evaluation, loan of equipment, and checking for overdue equipment. The production of correspondence was slightly slower with the computer. b. All outpatient episodes, but only 43 of 65 of inpatient episodes, were captured. Lung function and managerial report data were accurate using both manual and computerised methods. The manual system for equipment loans was inefficient, and use of the computer resulted in the recovery of 221 nebulisers. c. Development costs for 1988–1990 were high. Only £1200 to £1845 per year was recovered directly from staff time saved by the computer but larger savings resulted from changes in work practice. After 10 years the projected deficit is £10 000 per annum in running costs.Conclusions—In comparison with the manual methods, the computer system has shown significant advantages which provide accurate information, with significant favourable effects on working practices. In evaluating computer systems used in clinical practice it is essential to ensure that the projected work practice benefits are achieved without unacceptable costs in staff time, inaccurate data and high financial outlay.

This financial, economic, and organizational behavior literatures have been reviewed in order to evaluate three competing theories regarding ownership and management of the firm: 1) firms are not affected in terms of performance and policy by control status; 2) owner-controlled firms attempt to provide larger dividend payouts; and 3) owner-controlled firms tend to have smaller dividend payouts. No generalizations regarding either the superiority or the equality of employee-owned firms to professionally-managed firms can be drawn.

Over the past decade or so, several commentators have called for mission-driven research programs on solar geoengineering, also known as solar radiation management (SRM) or climate engineering. Building on the largely epistemic reasons offered by earlier commentators, this paper argues that a well-designed mission-driven research program that aims to evaluate solar geoengineering could promote justice and legitimacy, among other valuable ends. Specifically, an international, mission-driven research program that aims to produce knowledge to enable well-informed decision-making about solar geoengineering could (1) (...) provide a more effective way to identify and answer the questions that policymakers would need to answer; and (2) provide a venue for more efficient, effective, just, and legitimate governance of solar geoengineering research; while (3) reducing the tendency for solar geoengineering research to exacerbate international domination. Thus, despite some risks and limitations, a well-designed mission-driven research program offers one way to improve the governance of solar geoengineering research relative to the ‘investigator-driven’ status quo.

Previous research suggests that early performance of amnesic individuals in a probabilistic category learning task is relatively unimpaired. When combined with impaired declarative knowledge, this is taken as evidence for the existence of separate implicit and explicit memory systems. The present study contains a more fine-grained analysis of learning than earlier studies. Using a dynamic lens model approach with plausible learning models, we found that the learning process is indeed indistinguishable between an amnesic and control group. However, in contrast to (...) earlier findings, we found that explicit knowledge of the task structure is also good in both the amnesic and the control group. This is inconsistent with a crucial prediction from the multiple-systems account. The results can be explained from a single system account and previously found differences in later categorization performance can be accounted for by a difference in learning rate. (shrink)

This article surveys the latest research on risky-choice framing effects, focusing on the implications for rational decision-making. An influential program of psychological research suggests that people's judgements and decisions depend on the way in which information is presented, or ‘framed’. In a central choice paradigm, decision-makers seem to adopt different preferences, and different attitudes to risk, depending on whether the options specify the number of people who will be saved or the corresponding number who will die. It is standardly assumed (...) that such responses violate a foundational tenet of rational decision-making, known as the principle of description invariance. We discuss recent theoretical and empirical research that challenges the dominant ‘irrationalist’ narrative. These approaches typically pay close attention to how decision-makers represent decision problems (including their interpretation of numerical quantifiers or predicate choice) and they highlight the need for a more robust characterization of the description invariance principle. We conclude by indicating avenues for future research that could bring us closer to a complete—and potentially rationalizing—explanation of framing effects. (shrink)

This is the best overview of Foucault's work to date. A principal architect of poststructuralism, Michel Foucault reshaped the varied disciplines of history, philosophy, literary theory, and social science. David Shumway has provided, for the nonspecialist, a systematic analysis of the works of Foucault that is both thorough and accessible. Shumway connects Foucault's various conceptual and linguistic techniques to the basic critical strategies and purpose of his philosophy.

It is human nature to wonder how things might have turned out differently--either for the better or for the worse. For the past two decades psychologists have been intrigued by this phenomenon, which they call counterfactual thinking. Specifically, researchers have sought to answer the "big" questions: Why do people have such a strong propensity to generate counterfactuals, and what functions does counterfactual thinking serve? What are the determinants of counterfactual thinking, and what are its adaptive and psychological consequences? This important (...) work brings together a collection of thought-provoking papers by social and cognitive psychologists who have made important theoretical and empirical contributions to our understanding of this topic. The essays in this volume contain novel theoretical insights, and, in many cases descriptions of previously unpublished empirical studies. The Psychology of Counterfactual Thinking provides an excellent overview of this fascinating topic for researchers, as well as advanced undergraduates and graduates in psychology--particularly those with an interest in social cognition, social judgment, decision judgment, decision making, thinking and reasoning.

"Understanding Phenomenology" provides a guide to one of the most important schools of thought in modern philosophy. The book traces phenomenology's historical development, beginning with its founder, Edmund Husserl and his "pure" or "transcendental" phenomenology, and continuing with the later, "existential" phenomenology of Martin Heidegger, Jean-Paul Sartre, and Maurice Merleau-Ponty. The book also assesses later, critical responses to phenomenology - from Derrida to Dennett - as well as the continued significance of phenomenology for philosophy today. Written for anyone coming to (...) phenomenology for the first time, the book guides the reader through the often bewildering array of technical concepts and jargon associated with phenomenology and provides clear explanations and helpful examples to encourage and enhance engagement with the primary texts.

The first clear and faithful guide to the timeless, practical teachings of the Stoic philosopher Seneca. Stoicism, the most influential philosophy of the Roman Empire, offers refreshingly modern ways to strengthen our inner character in the face of an unpredictable world. Widely recognized as the most talented and humane writer of the Stoic tradition, Seneca teaches us to live with freedom and purpose. His most enduring work, over a hundred "Letters from a Stoic" written to a close friend, explains how (...) to handle adversity; overcome grief, anxiety, and anger; transform setbacks into opportunities for growth; and recognize the true nature of friendship. In Breakfast with Seneca, philosopher David Fideler mines Seneca's classic works in a series of focused chapters, clearly explaining Seneca's ideas without oversimplifying them. Best enjoyed as a daily ritual, like an energizing cup of coffee, Seneca's wisdom provides us with a steady stream of time-tested advice about the human condition-which, as it turns out, hasn't changed much over the past two thousand years.

Do dissociations imply independent systems? In the memory field, the view that there are independent implicit and explicit memory systems has been predominantly supported by dissociation evidence. Here, we argue that many of these dissociations do not necessarily imply distinct memory systems. We review recent work with a single-system computational model that extends signal-detection theory (SDT) to implicit memory. SDT has had a major influence on research in a variety of domains. The current work shows that it can be broadened (...) even further in its range of application. Indeed, the single-system model that we present does surprisingly well in accounting for some key dissociations that have been taken as evidence for independent implicit and explicit memory systems.

This philosophy of education paper describes a schizophrenic situation. A new airport is being planned in the locale of a university which is a Centre of Excellence of Education for Sustainable Development, and the university is a major partner. The airport involves an investment in jobs, resources, and will encourage further economic development. The planners have named the inter-connected developments around the airport as the ‘Aerotropolis’, including new university facilities. One could argue that the airport is a classic example of (...) the ‘Capitalocene’, where capital rushes into a new project, and environmental costs are ignored. This paper will execute a schizoanalytic critique of the process, from the perspective of a university education researcher caught up in the rushing flows of capital. Schizoanalysis has been chosen as the educational methodology to analyse this situation, because the researcher is part of what is happening, and is turned inside out by the designation in their region of the new airport. This paper is positioned in education between capital and the environment – it will describe from an insider’s perspective what it is like to be possessed, evacuated, sold out, and exploited by capital.

One central question of climate justice is how to fairly allocate the global emissions budget. Some commentators hold that the concept of fairness is hopelessly equivocal on this point. Others claim that we need a complete theory of distributive justice to answer the question. This paper argues to the contrary that, given only weak assumptions about fairness, we can show that fairness requires an allocation that is at least as prioritarian as the equal per capita view. Since even the equal (...) per capita view is more prioritarian than is politically feasible, fairness is univocal enough for all practical purposes. (shrink)

The following essay starts with a poem produced by ChatGPT after being prompted to “write a poem using combinations of words not found anywhere on the Internet as far as your data knows.” The poem includes the word “amorphigrist,” which inspired a second prompt stating, “Now write a long academic styled essay about ontology as the amorphigrist.” The essay was then edited and revised by this author to add philosophical background and complexity. Further prompts such as “Add a paragraph where (...) the duality between thought and material encounters is put into conversation with the duality between permanence and change” were given. What results is a human-nonhuman philosophy, an Amorphigrist Ontology. (shrink)

The world as perceived by human beings is full of colour. The world as described by physical scientists is composed of colourless particles and fields. Philosophical theories of colour since the scientific revolution have been primarily driven by a desire to harmonize these two apparently conflicting pictures of the world. Any adequate theory of colour has to be consistent with the characteristics of colour as perceived without contradicting the deliverances of the physical sciences. Given this conception of the aim of (...) a theory of colour, there are three possibilities for resolving the apparent conflict between the scientific and perceptual facts. The first possibility is to deny that physical objects have colours. Theories of this kind admit that objects appear coloured but maintain that these appearances are misleading. The conflict is resolved by removing colour from the external world. Second, it might be that colour is a relational property. For an object to possess a particular colour it must be related in the right way to a perceiver. One common version of this view analyzes colour as a disposition to cause particular kinds of perceptual experiences in a human being. Since the physical sciences deal only with the intrinsic properties of physical objects and their relations to other physical objects and not their relations to perceiving subjects, the possibility of conflict is removed. A third possible response to the conflict is to maintain that colour really is a property of external objects and that the conflict is merely apparent. Some theories of this form maintain that colour is identical to a physical property of objects. Others maintain that colour is a property that physical objects possess over and above all their physical <blockquote> 1 </blockquote> properties. Philosophical discussions of colour typically take the form of either elaborating on one of these three possibilities or attempting to show more generally that one of these three types of responses is to be preferred to the others..

Colour has often been supposed to be a subjective property, a property to be analysed orretly in terms of the phenomenological aspects of human expereince. In contrast with subjectivism, an objectivist analysis of color takes color to be a property objects possess in themselves, independently of the character of human perceptual expereince. David Hilbert defends a form of objectivism that identifies color with a physical property of surfaces - their spectral reflectance. This analysis of color is shown to provide (...) a more adequate account of the features of human color vision than its subjectivist rivals. The author's account of colro also recognises that the human perceptual system provides a limited and idiosyncratic picture of the world. These limitations are shown to be consistent with a realist account of colour and to provide the necessary tools for giving an analysis of common sense knowledge of color phenomena. (shrink)

The triumph of democracy has been heralded as one of the greatest achievements of the twentieth century, yet it seems to be in a relatively fragile condition in the United States, if one is to judge by the proliferation of editorials, essays, and books that focus on politics and distrust of government. Doubt and the Demands of Democratic Citizenship explores the reasons for public discontent and proposes an account of democratic citizenship appropriate for a robust democracy. David Hiley argues (...) that citizenship is more than participating in the electoral process. It requires a capacity to participate in the deliberative process with other citizens who might disagree, a capacity that combines deep convictions with a willingness to subject those convictions. Hiley develops his argument by examining the connection between doubt and democracy generally, as well as through case studies of Socrates, Montaigne, and Rousseau, interpreting them in light of contemporary issues.

In the current era patient autonomy is enormously important. However, recently there has also been some movement back to ensure that trust in the doctor's skill, knowledge and virtue is not excluded in the process. These new nuances of informed consent have been referred to by terms such as beneficent paternalism, experience-based paternalism and we would add virtuous paternalism. The purpose of this paper is to consider the history and current problematic nature of counselling and consent. Starting with the tradition (...) founded by Hippocrates we trace and seek to understand how relevant aspects of the patient-doctor relationship have evolved under the influences of subsequent moral theories. Finally we tentatively endorse certain modes of counselling in the current era in order to promote morally sound, good clinical practice. (shrink)

Experts often communicate probabilities verbally (e.g., unlikely) rather than numerically (e.g., 25% chance). Although criticism has focused on the vagueness of verbal probabilities, less attention has been given to the potential unintended, biasing effects of verbal probabilities in communicating probabilities to decision-makers. In four experiments (Ns = 201, 439, 435, 696), we showed that probability format (i.e., verbal vs. numeric) influenced participants’ inferences and decisions following a hypothetical financial expert’s forecast. We observed a format effect for low probability forecasts: verbal (...) probabilities were interpreted more pessimistically than numeric equivalents. We attributed the difference to directionality, a linguistic property that biases attention toward an outcome. In the high-probability conditions, the directionality of verbal and numeric probabilities aligned (both were positive), whereas they differed in the low-probability conditions (verbal probabilities were more negative). Participants inferred recommendations congruent with the communicated direction and these inferences mediated the effect of probability format on decisions. (shrink)

Employing three methods of assessing meaning, this book demonstrates that the thousands of human identities in English coalesce into groups that are recognizable as role sets in the contemporary social institutions of economy, kinship, religion, polity, law, education, medicine, sport, and arts. After establishing a theoretical and a methodological framework for his empirical work, David Heise presents the results obtained when meanings are assessed via dictionary definitions, collocates, and word associations. A close comparison of the results reveals that similar (...) outcomes are obtained through each of these three different approaches of defining meaning. The final chapter summarizes the study, considers the benefits and limitations of studying society via language, and applies the results to describing how individuals operate social institutions via their daily social interactions. Aspects of this book will be of interest to social psychologists, sociologists, and linguists. (shrink)

There are serious reasons for accepting each of these propositions individually but there are apparently insurmountable difficulties with accepting all three of them simultaneously if we assume that color is a single property. 1) and 2) together seem to imply that there is some property which all organisms with color vision can see and 3) seems to imply that there can be no such property. If these implications really are valid then one or more of these propositions will have to (...) be rejected in spite of whatever reasons can be given for their apparent acceptability. Before going on to discuss possible resolutions of this apparent contradiction it is worth pointing out there our three propositions are not all of a kind. Proposition 1) is a metaphysical thesis about the ontological status of color and proposition 3) is an empirical thesis about what properties organisms with color vision are capable of detecting. If you accept 1) then 2) will appear to verge on the trivial, but if 1) is denied then the status of 2) will appear more problematic. In what follows I will have more to say about why we either should or should not accept all three of these propositions. (shrink)
