Recent advances in the field of statistical learning have established that learners are able to track regularities of multimodal stimuli, yet it is unknown whether the statistical computations are performed on integrated representations or on separate, unimodal representations. In the present study, we investigated the ability of adults to integrate audio and visual input during statistical learning. We presented learners with a speech stream synchronized with a video of a speaker’s face. In the critical condition, the visual (e.g. /gi/) and (...) auditory (e.g. /mi/) signals were occasionally incongruent, which we predicted would produce the McGurk illusion, resulting in the perception of an audiovisual syllable (e.g. /ni/). In this way, we used the McGurk illusion to manipulate the underlying statistical structure of the speech streams, such that perception of these illusory syllables facilitated participants’ ability to segment the speech stream. Our results therefore demonstrate that participants can integrate audio and visual input to perceive the McGurk illusion during statistical learning. We interpret our findings as support for modality-interactive accounts of statistical learning. (shrink)

Ample research links mothers’ postpartum depression (PPD) to adverse interactions with their infants. However, most studies relied on general population samples, whereas a substantial number of women are at elevated depression risk. The purpose of this study was to describe mothers’ interactions with their 6- and 12-month-old infants among women at elevated risk, although with a range of symptom severity. We also identified higher-order factors that best characterized the interactions and tested longitudinal consistency of these factors from 6 to 12 (...) months of infant age. We leveraged data from eight projects across the United States (n = 647), using standardized depression measures and an adaptation of the NICHD Mother-Infant Interaction Scales. Overall, these depression-vulnerable mothers showed high levels of sensitivity and positive regard and low levels of intrusiveness, detachment, and negative regard with their infants. Factor analyses of maternal behaviors identified two overarching factors—“positive engagement” and “negative intrusiveness” that were comparable at 6 and 12 months of infant age. Mothers’ ability to regulate depressed mood was a key behavior that defined “positive engagement” in factor loadings. An exceptionally strong loading of intrusiveness on the second factor suggested its central importance for women at elevated depression risk. Mothers with severe depressive symptoms had significantly more “negative intrusiveness” and less “positive engagement” with their 6-month-old infants than women with moderate or fewer depressive symptoms, suggesting a potential tipping point at which symptoms may interfere with the quality of care. Results provide the foundation for further research into predictors and moderators of women’s interactions with their infant among women at elevated risk for PPD. They also indicate a need for evidence-based interventions that can support more severely depressed women in providing optimal care. (shrink)

Selection on grandparental investment is more complex than Coall & Hertwig (C&H) propose. Patterns of investment are subject to an intergenerational conflict over how resources should be distributed to maximize fitness. Grandparents may be selected to distribute resources unevenly, while their descendants will be selected to manipulate investment in their own favor. Here we outline the evolutionary basis of this conflict.

Celebrations of the second centenary of Hegel's birth have already begun, and more are planned. The Sixteenth Annual Wheaton College Philosophy Conference, "The Philosophy of Hegel on the 200th Anniversary of His Birth", was held November 6th and 7th at Wheaton, Illinois. Errol Harris of Northwestern delivered the Keynote lecture titled "The Importance of Hegel Today". Other papers read included "Hegel's Dialectic" by William Young of the University of Rhode Island; "Hegel and Contemporary Theology" by Merold Westphal of Yale; "Hegel (...) and the Existentialists on the Nature of the Self" by John C. Pageler of Wheaton College, and "Hegel, Marcuse, and the New Left" by Bernard Zylstra, Institute of Christian Studies, Toronto. * * * The Toronto Chapter of the Conference on Political Thought will sponsor a Symposium on "Hegel's Social and Political Thought" early next May. Interested persons are advised to contact Professor H.S. Harris, Department of Philosophy, Glendon College, York University, Toronto 12, Ontario, Canada. * * *Marquette University will conduct a major international symposium early in June, 1970, devoted to the intellectual legacy of Hegel. Preliminary plans call for a four day conference covering Hegel's influence in social and political philosophy and theory, his influence in philosophy of religion end theology, his influence in philosophy and theory of history, and current and projected efforts in editing and translating his writings. Principal participants include Shlomo Avineri of the Hebrew University, Jerusalem; Jean-Yves Calvez of L'Institut d'Etudes politiques de Paris; Emile Fackenheim of the University of Toronto; J.N. Findlay and Kenley Dove of Yale; Eric Well of L'Universite de Lille; Otto Pöggeler, Director of the Hegel-Archiv; James Doull of Dalhousie University ; Kenneth Schmitz of the Catholic University, and others. The unique format for the program is designed to permit maximum participation and discussion, and the Proceedings will be published. The Owl will give full details in the Winter or Spring issue. Interested persons should contact either Professor Joseph O'Malley or Professor Lee C. Rice, Co-Directors, Department of Philosophy. Marquette University, 62/north 13th Street, Milwaukee, Wisconsin 53233, * * * A World Hegel Congress is to be held in Berlin in August, 1970, under the auspices of the Internationale Hegel Gesellschaft. More on this will also be provided in forthcoming issues of The 0wl of Minerva. (shrink)

This article explores Presocratic epistemology, arguing that divine revelation is replaced as a warrant for knowledge with naturalistic accounts of how and what we humans can know; thus replacing earlier Greek pessimism about knowledge with a more optimistic outlook that allows for human discovery of the truth. A review of the relevant fragments and testimonia shows that Xenophanes, Alcmaeon, Heraclitus, and Parmenides—even Pythagoras and Empedocles—all moved some distance away from the older “god-oriented” view of knowledge toward a more secular and (...) optimistic outlook. But to get some sense of the dynamics at work in this transition this article begins, as virtually every account of early Greek thought must begin, with Homer and Hesiod. (shrink)

The contributions to this special collection concern issues and problems discussed in or related to the work of Wesley C. Salmon. Salmon has long been noted for his important work in the philosophy of science, which has included research on the interpretation of probability, the nature of explanation, the character of reasoning, the justification of induction, the structure of space/time and the paradoxes of Zeno, to mention only some of the most prominent. During a time of increasing preoccupation with historical (...) and sociological approaches to under standing science (which characterize scientific developments as though they could be adequately analysed from the perspective of political movements, even mistaking the phenomena of conversion for the rational appraisal of scientific theories), Salmon has remained stead fastly devoted to isolating and justifying those normative standards distinguishing science from non-science - especially through the vindi cation of general principles of scientific procedure and the validation of specific examples of scientific theories - without which science itself cannot be (even remotely) adequately understood. In this respect, Salmon exemplifies and strengthens a splendid tradi tion whose most remarkable representatives include Hans Reichenbach, Rudolf Carnap and Carl G. Hempel, all of whom exerted a profound influence upon his own development. (shrink)

This collection of essays is the definitive version of a widely discussed debate over the origins of the New Theory of Reference. In new articles, written especially for this volume, Quentin Smith and Scott Soames, the original participants in the debate, elaborate their positions on who was responsible for the ideas that Saul Kripke presented in his Naming and Necessity. They are joined by John Burgess, who weighs in on the side of Soames, while Smith adds a further dimension in (...) discussing the contributions of philosophers such as Follesdal, Geach, Hintikka, and Plantinga. Also included are lengthy excerpts from Follesdal's 1961 Harvard dissertation and a careful examination by Sten Lindstrom of the respective contributions of Kripke and Stig Kanger to the development of modal semantics. The collection will be essential reading for anyone acquainted with these influential ideas. (shrink)

This additional volume offers a revised edition of Lingua , Erasmus’ work on language, its possibilities and the dangers in its use, ending in a praise of the Word of God. Since it deals with the moral implications of language, Erasmus placed it in Ordo IV that comprises works on moral issues.

In many theories in contemporary philosophy of mind, attention is constitutively linked to phenomenal consciousness. Ned Block has recently argued that ‘identity crowding’ provides an example of subjects consciously seeing something to which they are unable to attend. Here I examine the reasons that Block gives for thinking that this is a case of a consciously perceived item that we are unable to attend to, and I offer a different interpretation.

By the death, last summer, of Jack Robson, the world of utilitarian studies and a wider world of scholarship on both sides of the Atlantic lost one of their most distinguished figures. It would not be appropriate here, even if it were possible now, to attempt a full and measured assessment of his work. Writing only a few months after the news of his death, while the sense of loss is still so sharp for all his many friends, two things (...) are possible. Something can and should be said to acknowledge and celebrate Robson's achievement as a scholar; and to this can be added some personal recollections of one whose human qualities were as outstanding as his scholarship.
