The computational value of debate in defeasible reasoning

Defeasible reasoning is concerned with the logics of non-deductive argument. As is described in the literature, the study of this type of reasoning is considerably more involved than the study of deductive argument, even so that, in realistic applications, there is often a lack of resources to perform an exhaustive analysis. It follows that, in a theory of defeasible reasoning, the order and direction in which arguments are developed, i.e. theprocedure, is important. The aim of this article is to show that debate is the most efficient procedure to argue in the presence of limited resources. To do so, there is first some general theory on defeasible argumentation, which is followed by an introduction to the problem of dialectical search. The problem of dialectical search is (or at least, should be) the essential issue in every theory on argumentation, and emerges at every occasion that involves adjudication on competing arguments. Starting with an example, it is explained that dialectical search can be best scheduled according to classical debating techniques, that work along well-tried methods. These methods (which include various forms of curtailment, interruption, and interpretation) have proven their value in keeping debating efforts within reasonable bounds. How they apply in a theory of formal argument, will be shown in this article.This research was made possible by SION, and is financed by NWO under contract number 612-316-019.

Beyond his story: from interpretation to impact of stories from different cultures

This paper deals with the history of psychoanalysis (Freud) and analytical psychology (Jung) in the light of recent developments and considers the release of new creativity in the field after its deconstruction. Cross-cultural contributions in the form of teaching stories are estimated to be of relevance, while the emphasis will be on what we, as analysts, can learn from these teachings, rather than interpreting them in the more traditional way in which such stories can be shown to fit analytical theory.
The most crucial debate in psychoanalysis of the recent era centres around stories and the deconstruction thereof. It is the debate between Lacan and Derrida on the interpretation of a crucial story (Poe's story, The Purloined Letter). The core of their views will be discussed in this paper in the light of the major differences between Freud and Jung. Whereas Freud's theoretical core-complex is closely related to Lacan's phallocentric Truth, it is Derrida who speaks of germination and dissemination as the way in which Truth manifests itself. Derrida's thought on text and words is very close to Jung's conceptions of the image and symbol, in which there is no monotheistic paradigm ruling theory     

Indexical and symbolic referencing: what role do they play in children's success on theory of mind tasks?

Numerous measures have been employed in the last 17 years to assess theory of mind (ToM). The literature reports marked variability in the age at which children succeed on these measures. To account for this variability, researchers have provided explanations ranging from cognitive shifts and voids to the inability to understand the language of the tasks or to social/pragmatic considerations, all of which tell us little if anything about the internal mechanism underlying ToM. The main purpose of this paper is to provide a comprehensive theoretical account of children's success and the discrepancies found across different ToM tasks. We test the hypothesis that children's understanding of ToM is sensitive to the basic elements of language, that is, to whether the language is indexical or symbolic. Support for this account was found in the analysis of selected test protocols in four published studies of ToM, and new data collected from 53 children (4--6 years) which showed that a higher percentage of children succeeded on tasks with a high ratio of indexical to symbolic references than on tasks with a high ratio of symbolic to indexical references. There was also a main effect of age with older children succeeding at higher rates on both tasks than younger children. Our findings suggest that indexical representation can afford ToM understanding in 4-year-olds, but is not sufficient for a more mature ToM. The latter requires symbolic representation that was demonstrated by the majority of 5--6-year-olds.     

Postpartum depression and attachment: Is anybody here?

Abstract

The paper presents a developmental and dynamic multitheoretical overview of many dimensions of attachment-related processes activated under the conditions of maternal depression. The clinical vignette (from the analytic practice of Eva D. Papiasvili) of reconstructive anaytic work with an adult patient illustrates the profound impact of maternal depression on precocious early differentiation between the attachment styles, of the depressed parent and the substitute caregiver, at the root of early “counterdependent” self-sufficiency. Through reconstructive interpretive work, first with enactments and then dreams, pertaining to not-remembered, represented, or symbolized events of earliest infancy, the patient is able to make a series of developmentally transformative symbolic leaps, restoring the capacity for intimacy, hope, trust, and pleasure. This breaks the intergenerational mother–daughter transmission of postpartum depression and related problematic attachment.

On Theoretical Edges and Exclusionary Borders: Towards a Genealogy of “Analyzability” in Jungian Psychoanalysis1

An oft-repeated and largely unexamined assumption in Jungian psychoanalysis is the notion of “analyzability”, that is, of an individual's ability or present capacity to think symbolically. It is often taught that if someone is unable to think symbolically, a depth analysis is not possible. Such an individual may be more aptly suited for supportive psychotherapy, the argument goes, an experience that may very well lead to the development of the ego's capacity for symbolic thought but is not, in and of itself, a Jungian analysis. While this sort of categorical thinking has, at times, crossed over into ontological claims about individuals and groups, the notion of analyzability encountered in psychoanalytic theory and praxis is often cloaked in facially neutral language. The impact, however, has been anything but neutral in effect. In this paper, I propose a softening of our theoretical edges through a genealogy of the category of analyzability within the broader history of psychoanalysis. Through this excavation, I explore the contingent nature of the category of analyzability, how it has constricted knowledge, perpetuated inequality, and, more broadly, obscured ways of knowing. In so doing, I recover the radically democratic potential that lies at the heart of Jungian psychoanalysis.     

Short-term memory for responses: the "choose-small" effect

Pigeons' short-term memory for fixed-ratio requirements was assessed using a delayed symbolic matching-to-sample procedure. Different choices were reinforced after fixed-ratio 10 and fixed-ratio 40 requirements, and delays of 0, 5, or 20 s were sometimes placed between sample ratios and choice. All birds made disproportionate numbers of responses to the small-ratio choice alternative when delays were interposed between ratios and choice, and this bias increased as a function of delay. Preference for the small fixed-ratio alternative was also observed on "no-sample" trials, during which the choice alternatives were presented without a prior sample ratio. This "choose-small" bias is analogous to results obtained by Spetch and Wilkie (1983) with event duration as the discriminative stimulus. The choose-small bias was attenuated when the houselight was turned on during delays, but overall accuracy was not influenced systematically by the houselight manipulation.
