A maximum likelihood hierarchical disaggregate model for predicting choices of individuals

The absence of operational disaggregate lexicographic decision models and Tversky's observation that choice behavior is often inconsistent, hierarchical, and context dependent motivate the development of a maximum likelihood hierarchical (MLH) choice model. This new disaggregate choice model requires few assumptions and accommodates the three aspects of choice behavior noted by A. Tversky (1972, Journal of Mathematical Psychology, 9, 341–367). The model has its foundation in a prototype model developed by the authors. Unlike the deterministic prototype, however, MLH is a probabilistic model which generates maximum likelihood estimators of the aggregate “cutoff values.” The model is formulated as a concave programming problem whose solutions are therefore globally optimal. Finally, the model is applied to data from three separate studies where it is demonstrated to have superior performance over the prototype model in its predictive performance.     

Towards a new philosophy of education: Extending the conversational metaphor for thinking

Recently, feminists like Jane Roland-Martin, Elizabeth Young-Bruehl, and others have advocated a conversational metaphor for thinking and rationality, and our image of the rational person. Elizabeth Young-Bruehl refers to thinking as a constant interconnecting of representations of experiences and an extension of how we hear ourselves and others. There are numerous disadvantages to thinking about thinking as a conversation.We think there are difficulties in accepting the current formulation of the conversational metaphor without question. First, there is danger that we will lose important dialectical connections like that between the self and society. Second, the conversational metaphor alone cannot fully express the way conversations are constructed. We will want to take up the notion of narrative as a metaphor for thinking advocated by Susan Bordo, Alasdair MacIntyre, Jerome Bruner, and others, including Mary Belenky and her colleagues.Eventually, we want to champion narrative and the dramatic narrative of culture as a metaphor for thinking that involves such expressions as sights, insights, silences, as well as sounds, moments of mood and poetic moments. The dramatic narrative provides the structural possibilities needed to criticize certain kinds of conversations, in order to talk about the relations of public and private, self and society and most importantly, about the drama of our lives within and without.The dramatic narrative for thinking helps dispel the dangerous dualisms of mind and body that not even conversation or narration alone can banish, and allows us to frame questions about education that do not require us to separate mind from body. The dramatic narrative metaphor for thinking lets us show who we are, act out what we think, and reconstruct rationality to reflect what many women, and some men, do.     

Peripheral information extraction: A developmental examination of reading processes

Three experiments examining the information extraction processes are presented. In Experiments I and II, adults and children were presented paragraphs to read and search for specified targets, respectively. Two types of typographical (spatial) manipulations were used: case of the letters within the paragraphs was as normally experienced, or in alternating upper and lower case letters. Spacing between words was either as normal, filled with a neutral symbol, or absent. The response measures were reading and search speed in words per minute. Sensitivity to case (word shape) and space (word boundary) increased as a function of experience and was different for reading compared with search. In Experiment III subjects were asked to judge whether briefly presented pairs of letters were the same or different. Retinal (spatial) location was varied from trial to trial; dependent measure was reaction time. Results showed a developmental progression in response time with complex interactions. Theoretical interpretations of these data are discussed in support of the initial stage of Hochberg's peripheral to cognitive search guidance model.     

CONSIDERING STANLEY HAUERWAS

After introducing the five articles that comprise this focus issue, I consider Hauerwas's claim that he is a theologian without a position. The claim has merit, I hold, since Hauerwas writes in response to what he reads, which is his way of learning it better. Moreover, he writes socially, characteristically soliciting help from his friends. As such, he purposefully makes himself accountable to those he addresses. In his later years this accountability has extended especially to the Church and to the Bible, which helps explain why Hauerwas cares so deeply about his sermons, which he takes to be his most important work.

Changes in Children's Episodic Narratives Through Long-Term Repeated Recall: Longitudinal Case Studies1

This study aimed to investigate whether a child's narrative of a particular past episode would change in repeated reporting over the long term, and if so, how it would change. To answer these questions, I conducted longitudinal case studies of episodic reports by children every 2–6 months, from their early childhood to the age of 10–15 years. Criteria for inclusion were set in advance; seven episodic narratives meeting these criteria were analyzed. Two types of changes in the narratives were observed, as expected: that of including other information, and that of an event suddenly being reported after no recall for several years. Information from the children's surroundings seemed to be substantially involved in these changes in their episodic narratives. The present results also indicate that mothers' episodic memories are not always reliable and that the schema children have can influence their episodic memories.     

The Experience of Time in Acute Psychosis and Schizophrenia

From the narrative point of view the plot of a story configures time. In psychosis, when experiences remain unnarrated, experience being-in-time is also missing. Once experiences are given narrative form, they can be left behind as a part of individual's personal history, thus enabling present experiences to be narrated. Unnarrated experiences do not accumulate. Narrative history contains, however, enough redundancy to invite you to restory your past in a new way if you need to. Hence, from the narrative point of view, early, family- and network-centered intervention is of special value in cases of acute psychosis.     

Expressed Emotion In The Narrative Context of Family Photographs

This study aims to elucidate cognitive and contextual aspects of the EE (Expressed Emotion) concept. The EE levels of both parents of two first admission psychotic patients were rated from the Five Minute Speech Sample (FMSS), and the emotional responses were further analyzed in narratives of family photographs. The attribution model was found to provide an explanatory framework for understanding relatives' expressed emotions (EE) toward a family member suffering from psychotic disturbances. Four case reports indicated that family photographs induced parents to create narratives in which emotions, attributions, and strategies for coping with stressful aspects of the illness came forward as intertwined phenomena. The method can offer more comprehensive data for intervention strategies aiming to alter the prevailing atmosphere and interaction patterns within the high EE family.     

Loving the World We Are: Anthropology and Relationality in Laudato si’

There is a tension between Laudato si's consistent emphasis on relationships and interconnectedness and its acceptance of anthropocentrism. While Laudato si’ does reject certain problematic forms of anthropocentrism, the encyclical does not assert an alternative to this traditional framework. This article contends that “relatiocentrism” provides the best avenue for developing the convictions expressed within Laudato si’ while moving beyond the limitations of the encyclical itself. In so doing, this essay explores the use of narrative as a means of shaping identity by mapping significant relationships and points of meaning. It examines the central anthropological claims of the encyclical and the tensions these create with anthropocentric narratives. And it examines relatiocentrism in light of the biblical creation accounts, the eschatological perspective of Laudato si’, and virtue ethics. The essay concludes by suggesting further theological and moral implications of this shift in perspective.     

The impact of seductive details and signaling on analogical transfer

This study tests if the seductive details effect on transfer is mitigated by signaling. Preservice teachers (N = 73) were randomly assigned on the basis of two factors, signaling and seductive details. After learning about principles of effective feedback, participants reflected on a narrative text case illustrating the instructional material that either contained or did not contain signals (highlighting key base text) and/or seductive details (interesting but extraneous details). Whereas no group differences for signaling, or signaling by seductive details interaction were found, a significant main effect for seductive details on transfer was found, Cohen's d = 0.51. These results suggest seductive details embedded in narrative cases negatively impact analogical transfer, and the effect is not mitigated by the inclusion of signaling. This lends support to the diversion hypothesis of seductive details, which suggests that seductive details damage learning by preventing meaningful encoding in appropriate schema.
