The ideas upon which public education was founded in the last half of the nineteenth century were wrong. And despite their continued dominance in educational thinking for a century and a half, these ideas are no more right today. So argues one of the most original and highly regarded educational theorists of our time in 'Getting It Wrong from the Beginning'. Kieran Egan explains how we have come to take mistaken concepts about education for granted and why this dooms our (...) attempts at educational reform. (shrink)
Looking is a fundamental exploratory behavior by which infants acquire knowledge about the world. In theories of infant habituation, however, looking as an exploratory behavior has been deemphasized relative to the reliable nature with which looking indexes active cognitive processing. We present a new theory that connects looking to the dynamics of memory formation and formally implement this theory in a Dynamic Neural Field model that learns autonomously as it actively looks and looks away from a stimulus. We situate this (...) model in a habituation task and illustrate the mechanisms by which looking, encoding, working memory formation, and long-term memory formation give rise to habituation across multiple stimulus and task contexts. We also illustrate how the act of looking and the temporal dynamics of learning affect each other. Finally, we test a new hypothesis about the sources of developmental differences in looking.

What responsibilities, if any, do we have towards our genetic offspring, before or after birth and perhaps even before creation, merely by virtue of the genetic link? What claims, if any, arise from the mere genetic parental relation? Should society through its legal arrangements allow 'fatherless' or 'motherless' children to be born, as the current law on medically assisted reproduction involving gamete donation in some legal systems does? Does the possibility of establishing genetic parentage with practical certainty necessitate reform of (...) current legal regimes of parenthood? And what limits, if any, should we set on parental procreative choices in the interests of future children, particularly with regard to genetic engineering and related techniques? These are the questions explored in this book by some of the foremost legal, bioethical and biomedical thinkers. Assembled with a view to assisting the reader to reflect critically on the ongoing social experiment which medically assisted reproduction is today, the essays in this collection highlight what are - and what else might in the nearby future become - possible reproductive options and respond to the difficulties we encounter in assessing these practices and possibilities from our traditional ethical vantage points.

Psychologists have long debated the underlying cause of infants' perseverative reaching. Thelen et al. explain the error in terms of general processes that make goal-directed actions to remembered locations. The context- and experience-dependent nature of their model implies that there is no single cause of the A-not-B error, and, more generally, no core essence to cognitive development.
The main goal of this paper is to argue against Karl Rogers's attacks on realism in physics. Rogers argues that electrons do not exist independently of the relevant socio-technological process, but I show that such an assumption would make our best scientific theories incomprehensible. While the paper supports Rogers's attempts to refute positivism, it demonstrates that his own position is positivistic, and it corrects his overemphasis on the roles of technology and the experimenter. Rogers assumes that the founders of modern (...) science were simply mechanists, but I show how they were actually Platonic realists. Contrary to Rogers, realist faith in the fundamental unifying power of the laws of physics is shown to be reasonable, and any denial of this belief would imply that science is impossible. (shrink)

Theories of cognitive development must address both the issue of how children bring their knowledge to bear on behavior in-the-moment, and how knowledge changes over time. We argue that seeking answers to these questions requires an appreciation of the dynamic nature of the developing system in its full, reciprocal complexity. We illustrate this dynamic complexity with results from two lines of research on early word learning. The first demonstrates how the child's active engagement with objects and people supports referent selection (...) via memories for what objects were previously seen in a cued location. The second set of results highlights changes in the role of novelty and attentional processes in referent selection and retention as children's knowledge of words and objects grows. Together this work suggests that understanding systems for perception, action, attention, and memory, and their complex interaction, is critical to understand word learning. We review recent literature that highlights the complex interactions between these processes in cognitive development and point to critical issues for future work. (shrink)
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)
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)
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.

In this paper we will argue that the ontology implicit in John Buridan’s modal octagon commits him to a form of contingentism. In particular, we will argue that Buridan is committed to denying the validity of the Barcan and converse Barcan formulae.

Using data from a survey of certified organic or in-transition to organic vegetable and dairy producers in Canada, we seek to understand a farmer’s decision to convert to organic production by exploring the motives, problems and challenges, and benefits of transition to organic. Results suggest that health and safety concerns and environmental issues are the predominant motives for conversion, while economic motives are of lesser importance. In contrast to the extant literature, results suggest that the motives underlying transition have not (...) changed overtime in Canada. Problems experienced during transition relate to lack of governmental and institutional support, negative pressure from other farmers and farm groups, and lack of physical and financial capital. Reduced exposure to chemicals and improved food quality were highly ranked benefits, while economic related benefits were scored among the lowest of the listed benefits. To prosper, the Canadian organic sector must overcome fundamental marketing problems and challenges. Promulgation of the Canada Organic standard may help address some marketing issues by providing more information to consumers. (shrink)
John Searle’s Chinese Room Argument purports to demonstrate that syntax is not sufficient for semantics, and, hence, because computation cannot yield understanding, the computational theory of mind, which equates the mind to an information processing system based on formal computations, fails. In this paper, we use the CRA, and the debate that emerged from it, to develop a philosophical critique of recent advances in robotics and neuroscience. We describe results from a body of work that contributes to blurring the (...) divide between biological and artificial systems; so-called animats, autonomous robots that are controlled by biological neural tissue and what may be described as remote-controlled rodents, living animals endowed with augmented abilities provided by external controllers. We argue that, even though at first sight, these chimeric systems may seem to escape the CRA, on closer analysis, they do not. We conclude by discussing the role of the body–brain dynamics in the processes that give rise to genuine understanding of the world, in line with recent proposals from enactive cognitive science.

In this study, a decision modeling approach is used to measure the relative importances of four social responsibility components. When given information concerning the economic, legal, ethical and philanthropic activities of 16 hypothetical organizations, 159 junior and senior management students judged the social responsibility of these firms. The study used two types of analysis: first, a within-subject regression, then a between-subject ANOVA. Results showed ethical behavior to be most important in judging social responsibility; legal behavior was second, discretionary behavior third, (...) and economic behavior was least important. In addition, all but one rater consistently applied the social responsibility components. The implications of these results and suggestions for future research are discussed. (shrink)
