Covariation and temporal contiguity as principles of causal inference in young children

Four- to seven-year-old children observed a simple physical effect which could be attributed to either a consistent but noncontiguous covariate or a contiguous but inconsistent covariate. When there was a physical rationale for the temporal delay between covariate and effect, children attributed the effect to the consistent but noncontiguous covariate. In the absence of such a rationale, they attributed the effect to the contiguous but inconsistent covariate. It was concluded that neither consistent covariation nor strict temporal contiguity were essential aspects of causal inference for these children.     

Using conjoint-measurement models to investigate a theory about probabilistic information processing

A theory of how opinions are formed and revised on the basis of probabilistic evidence is presented. The decision maker is viewed as a limited information processor who attends to the dimensions of a sample of equivocal information in a sequential fashion, beginning with the most salient dimension and continuing in decreasing order of salience. The contribution of each dimension level to the final opinion depends on the strength of association between that level and each of the two hypotheses under consideration. This theory is represented formally as an additive-difference model, various special cases of which correspond to other algebraic models in the literature. Two of the special cases were empirically investigated under varying levels of experience and payoffs, using the techniques of conjoint-measurement theory and ordinal data from individual subjects. The data provided reasonably good support for the models under all conditions investigated, and in addition showed interesting effects on salience and on processing of the independent variables.     

Renegotiating Aquinas

While Roman Catholic feminist ethicists typically endorse moral realism and crosscultural standards of justice, they also have been influenced by the postmodern interrogation of abstract reason and moral universalism. As theologians writing after the Second Vatican Council, they are increasingly sensitive to the communal and ecclesial dimensions of morality and of Christian ethics, and to the integral relation of Christian faith and ethics. This essay will consider two approaches to Catholic feminist ethics that differ in the relative weight they give to constructive work for social justice (realist gender justice ethics), or to the grounding of ethics in prayer and mysticism (postmodern gendered faith ethics). Using critical feminist reappropriations of the theology and ethics of Aquinas as examples, this essay will argue that the two approaches are overlapping and interdependent.     

Paradigm shift in religious education: a reply to Jackson,or why religious education goes to war

This article provides a defence of my theoretical analysis of paradigm shift in contemporary religious education, particularly in light of Robert Jackson’s (2015) article published in this journal: ‘Misrepresenting religious education’s past and present in looking forward: Gearon using Kuhn’s concepts of paradigm, paradigm shift and incommensurability’. The core of Jackson’s concerns is my adaptation of Kuhn’s concepts of paradigm, paradigm shift and incommensurability to religious education. Defending in turn my use of these concepts – of paradigm, paradigm shift and incommensurability – I conclude that Jackson’s critique is in and of itself an apt demonstration of the position he seeks to attack. Drawing wider parallels with the methodological ‘paradigm wars’ in the social sciences I argue that the paradigms are why religious education too goes to ‘war’.     

Introduction: Law and Disobedience

This essay considers some major questions raised by civil and other forms of conscientious disobedience. What distinguishes that form of dissent? Can we recognise the legitimacy of a political system yet defy its laws? Is disobeying a democratic decision especially or entirely unacceptable, or can disobedience be an instrument of democracy? If a regime recognises rights, how should we regard disobedience that appeals to those rights in challenging the regime’s laws? How should reasons for obedience figure in our thinking about justified disobedience? The essay locates the contributions that make up this special issue of Res Publica within these debates about disobedience. It questions whether any general theory of justified disobedience can command agreement: the conditions that give rise to conscientious disobedience -- conflicting values and judgements -- seem to preclude consensus on when its use is justified.     

The logical and empirical bases of conservation judgements

It is argued that conservation judgements are based on a particular combination of logical necessity and empirical belief. The empirical belief is that a given transformation will not alter a particular quantity (Elkind's conservation of identity). The logical aspect is a transitive deductive argument containing an initial equivalence of two quantities and the conservation of identity belief as premises which lead to the conclusion of maintained equivalence (Elkind's conservation of equivalence). In two experiments, it is shown that conservation of identity beliefs can be manipulated in subjects who have long since developed the capacity for transitive deductive inference. Untrained 10 year olds were unaware of how sublimation acts to alter certain quantities over particular transformations of shape. And untrained adults incorrectly believed that both the area and perimeter of a closed figure would be conserved over transformations which elongated the figure. Both groups of subjects could be trained in the correct conservation of identity beliefs and this affected their conservation of equivalence judgements in predicted ways. It is suggested that the locical aspect of conservation is developmentally stable and that the empirical aspect varies widely across problems and individuals because of its dependence on relevant experience.
