It is unclear how children learn labels for multiple overlapping categories such as “Labrador,” “dog,” and “animal.” Xu and Tenenbaum suggested that learners infer correct meanings with the help of Bayesian inference. They instantiated these claims in a Bayesian model, which they tested with preschoolers and adults. Here, we report data testing a developmental prediction of the Bayesian model—that more knowledge should lead to narrower category inferences when presented with multiple subordinate exemplars. Two experiments did not support this prediction. Children (...) with more category knowledge showed broader generalization when presented with multiple subordinate exemplars, compared to less knowledgeable children and adults. This implies a U-shaped developmental trend. The Bayesian model was not able to account for these data, even with inputs that reflected the similarity judgments of children. We discuss implications for the Bayesian model, including a combined Bayesian/morphological knowledge account that could explain the demonstrated U-shaped trend. (shrink)

In this year of bicentennial celebration, there will no doubt take place several cultural analyses of the American tradition. This is only as it should be, for without an extensive, broad-based inquiry into where we have come from, we shall surely not foresee where we might go. Nonetheless, most cultural analyses of the American context suffer from a common fault - the lack of a different context to use for purposes of comparison. True, American values and ideals were partly inherited (...) from the European tradition. But that tradition is in many ways an inadequate mode of comparison. Without going too far afield, let us note two points: first, European culture was the proud inheritor of the Renaissance tradition, and, going back still further, of classical culture; second, the European countries are compact. Their land masses are such that the notion of "frontier" simply would not have arisen in the same way as it did in America. On the other side of the globe, however, there does exist a country capable of serving as a suitable mirror. We speak, of course, of Russia. That country also came relatively late onto the cultural horizon, and was not privy to the Renaissance tradition. Furthermore, her land mass is such as to be "experi mentally infmite" in character - not unlike the American frontier. It is hoped that much can be leamed about the present cultural context by com paring the two countries in their youthful stages. (shrink)

According to Jones & Love (J&L), Bayesian theories are too often isolated from other theories and behavioral processes. Here, we highlight examples of two types of isolation from the field of word learning. Specifically, Bayesian theories ignore emergence, critical to development theory, and have not probed the behavioral details of several key phenomena, such as the effect.

To make behavioral choices that are in line with our goals and our moral beliefs, we need to gather and consider information about our current situation. Most information present in our environment is not relevant to the choices we need or would want to make and thus could interfere with our ability to behave in ways that reflect our underlying values. Certain sources of information could even lead us to make choices we later regret, and thus it would be beneficial (...) to be able to ignore that information. Our ability to exert successful self-governance depends on our ability to attend to sources of information that we deem important to our decision-making processes. We generally assume that, at any moment, we have the ability to choose what we pay attention to. However, recent research indicates that what we pay attention to is influenced by our prior experiences, including reward history and past successes and failures, even when we are not aware of this history. Even momentary distractions can cause us to miss or discount information that should have a greater influence on our decisions given our values. Such biases in attention thus raise questions about the degree to which the choices that we make may be poorly informed and not truly reflect our ability to otherwise exert self-governance. (shrink)

Marr's seminal work laid out a program of research by specifying key questions for cognitive science at different levels of analysis. Because dynamic systems theory focuses on time and interdependence of components, DST research programs come to very different conclusions regarding the nature of cognitive change. We review a specific DST approach to cognitive-level processes: dynamic field theory. We review research applying DFT to several cognitive-level processes: object permanence, naming hierarchical categories, and inferring intent, that demonstrate the difference in understanding (...) of behavior and cognition that results from a DST perspective. These point to a central challenge for cognitive science research as defined by Marr—emergence. We argue that appreciating emergence raises questions about the utility of computational-level analyses and opens the door to insights concerning the origin of novel forms of behavior and thought. We contend this is one of the most fundamental questions about cognition and behavior. (shrink)

Heyes's literature review of deception, imitation, and self-recognition is inadequate, misleading, and erroneous. The anaesthetic artifact hypothesis of self-recognition is unsupported by the data she herself examines. Her proposed experiment is tantalizing, indicating that theory of mind is simply a Turing test.

Peter Winch's The Idea of a Social Science has been the subject of repeated misunderstanding. This discussion takes one recent example and shows how Winch's argument is gravely distorted. What is at issue is not, as is usually supposed, whether we can accept or endorse another society's explanations of its activities, but whether we have to look for an explanatory connection between concepts and action. Winch's argument is that before we can try to explain actions, we have to identify them (...) correctly. This can only be done by seeing how they, and the concepts they are associated with, fit within a way of life. Grasping its rule?following character is understanding action. Once the difficulties in making such identifications are appreciated, we will be less inclined to accept facile explanations why people in other societies do the things they do. (shrink)

In this article, we defend the view that problematic epistemological extremism, which presents puzzles for many learners new to philosophy, is a result of earlier learning at the K–12 level. Confirming this hunch serves as a way of locating the problem and suggesting that recent learning interventions proposed by Christopher Edelman (2021) and Galen Barry (2022) are on the right track. Further, we offer that this extremism is plausibly described as what Miranda Fricker (2007) calls an epistemic injustice. This suggests (...) that disrupting the problem is a boon for learners, the discipline, and good citizenship. In our discussion we introduce work by Derek Muller suggesting that it is important to address the misconceptions involved in epistemological extremism (and its precursors) lest we simply reinforce these problematic misconceptions for the worse—inhibiting student learning, reproducing challenges to good citizenship, and leading to a discounting of many ways of knowing.

Everyone agrees that testing hypotheses is important, but Bowers et al. provide scant details about where hypotheses about perception and brain function should come from. We suggest that the answer lies in considering how information about the outside world could be acquired – that is, learned – over the course of evolution and development. Deep neural networks (DNNs) provide one tool to address this question.

This textbook offers a unique and accessible approach to ethical decision-making for practicing pharmacists and student pharmacists. Unlike other texts, it gives clear guidance based on the fundamental principles of moral philosophy, explaining them in simple language and illustrating them with abundant clinical examples and case studies. The strength of this text is in its emphasis on normative ethics and critical thinking, and that there is truly a best answer in the vast majority of cases, no matter how complex. The (...) authors place high trust in a pharmacist’s moral judgment. This teaches the reader how to think, based on ethical principles, not necessarily what to think. This means navigating between the two extremes of overly theoretical and excessively prescriptive. The cogent framework given in this text uses the language of competing duties, identifying the moral principles at stake that create duties for the pharmacist. This is the balancing act of normative ethics, and of deciding which duties should prevail in a given clinical situation. This work presents a clear-cut pathway for resolving ethical dilemmas encountered by pharmacists, based on foundational principles and critical thinking.

A major new source for research of the 19th century and history of ideas, this dictionary covers all of the major, and a range of the less well-known, thinkers and writers of the time.

Focusing on a discussion by Ruddich and Stassen of the ?Remarks on Frazer's Golden Bough?, this paper shows that some of the usual criticisms made by sociologists of Wittgenstein are misplaced. He does not reject causal explanations of beliefs and actions and replace them with some other form of explanation, but dismisses the idea that any explanation is called for here. His argument that the origin of the desire to explain beliefs is to be found in a misconceived parallel between (...) science and magic is explained and discussed. (shrink)
