A STRUCTURE-MAPPING APPROACH TO COGNITIVE DEVELOPMENT

Several contemporary theories of cognitive development appear to agree that children progress through a hierarchy of increasingly powerful cognitive organizations, and that higher-level organizations impose greater information-processing loads. Although theories differ in their method of defining both the levels and the information-processing loads they impose, it is possible to find considerable common ground. In this paper it is argued that the different levels of cognitive organization can be attributed to a hierarchy of structure-mapping rules. Structure mapping is part of the process by which children represent and understand concepts. Four levels of structure mapping are defined. The levels, from lowest to highest, are based on element mappings, relational mappings, system mappings and multiple-system mappings. The higher-level rules are more ‘abstract’ in the sense of being less dependent on specific properties of each task, and are more transferable. However, they also impose higher information-processing demands. Children who lack the information-processing capacity for a particular level of structure mapping will be able to attain concepts that belong to that level. The theory is used to predict the characteristic age of attainment of cognitive tasks including transitivity, classification, interpretation of algebraic expressions, analogies, logical reasoning, and hypothesis testing. It is argued that the four-structure mapping levels can subsume the four main stages of cognitive development.     

Induction of Relational Schemas: Common Processes in Reasoning and Complex Learning

Five experiments were performed to test whether participants induced a coherent representation of the structure of a task, called a relational schema, from specific instances. Properties of a relational schema include: An explicit symbol for a relation, a binding that preserves the truth of a relation, potential for higher-order relations, omnidirectional access, potential for transfer between isomorphs, and ability to predict unseen items in isomorphic problems. However relational schemas are not necessarily coded in abstract form. Predictions from relational schema theory were contrasted with predictions from configural learning and other nonstructural theories in five experiments in which participants were taught a structure comprised of a set of initial-state,operator → end-state instances. The initial-state,operator pairs were presented and participants had to predict the correct end-state. Induction of a relational schema was achieved efficiently by adult participants as indicated by ability to predict items of a new isomorphic problem. The relational schemas induced showed the omnidirectional access property, there was efficient transfer to isomorphs, and structural coherence had a powerful effect on learning. The “learning to learn” effect traditionally associated with the learning set literature was observed, and the long-standing enigma of learning set acquisition is explained by a model composed of relational schema induction and structure mapping. Performance was better after reversal of operators than after shift to an alternate structure, even though the latter entailed more overlap with previously learned tasks in terms of the number of configural associations that were preserved. An explanation for the reversal shift phenomenon in terms of induction and mapping of a relational schema is proposed. The five experiments provided evidence supporting predictions from relational schema theory, and no evidence was found for configural or nonstructural learning theories.     

The Problem of Religious Language ‘Look at it this way’ (Wittgenstein)*

This essay is critical of some of the attempts made to solve problems of meaning in religious languages, but remains open-minded about them and accepts the Wittgensteinian invitation to look at their dissolution by way of the experiences of meaning and the aspects of language on which they rely. I have argued that there were and are no lasting problems with religious language per se and that the force and meaning of what is said in using religious language over time and circumstance may vary even to the point of having to retrieve concepts feared lost. We may in addition give ourselves our own personal interpretations by which we want to live and discuss with those in our space of reasons where good conversation is ever an inexhaustible provision on the way to enlightened understanding. Furthermore, we are not merely passive recipients of the meanings and significance of the languages we know. Finally, much of the meaning of religious language comes with the experience of being struck again by what has always been loved and by new aspects of, or different ways of taking, what is presented.     

Relational processing following stroke

The research examined relational processing following stroke. Stroke patients (14 with frontal, 30 with non-frontal lesions) and 41 matched controls completed four relational processing tasks: sentence comprehension, Latin square matrix completion, modified Dimensional Change Card Sorting, and n-back. Each task included items at two or three levels of relational complexity. Relational processing was impaired in the stroke groups. This was due mainly to items at the intermediate ternary-relational level of complexity. Less complex binary-relational items and more complex quaternary-relational items (the latter are difficult for adults generally) were less sensitive to stroke status. Impairment was greater in frontal than non-frontal stroke patients. Positive inter-correlations among measures supported the domain-general nature of relational processing. Implications for assessment and intervention are discussed.

Attention and Executive Function Deficits in Adolescent Sex Offenders

Thirty male adolescent sex offenders and 20 age-matched male adolescents completed an extensive battery of attention and executive function tests. Controls were obtained from adolescents from a socially and economically deprived background, typical of the offending group. The attention battery was based on Mirksy, Anthony, Duncan, Ahearn, and Kellam (1991) and the executive function battery on Kelly (2000a). Successful matching for IQ was not achieved and therefore ANCOVA comparisons were made between the groups, with IQ as the covariate. In attention a highly significant difference was found on the focus-execute factor and a significant difference on the shift factor. In executive function there was a highly significant difference only on the response speed factor. In all cases better abilities were demonstrated by the control group. The importance of thorough neuropsychological investigation in the clinical assessment of this forensic group is supported. The clinical implications of neuropsychological deficits in terms of risk assessment and clinical management are discussed.     

THE AMAZING PLACENTA: EVOLUTION AND LIFELINE TO HUMANNESS

The placenta arose during mammalian evolution, which is recent in evolutionary terms. Genetic changes underlying placental development remain identifiable by the new science of comparative genomics (approximately post-2000). Randomly arising features of genomes including endogenous retroviruses and transposable elements have provided structural genes and gene-regulatory motifs responsible for innovations in placental biology. Stochastic genetic events indeed contribute to new functionality. Theologically, random mutations are part of the strategy by which the divine purpose for humanity is attained. Placental function critically underlies human brain development, and suboptimal function, associated with environmental conditions and maternal distress, contributes to mental health deficits in the offspring. Many enter life with handicaps arising from contingent events in utero, mandating understanding, compassion, and socioemotional support, imperatives native to moral including biblical values. The extended period of development afforded by placentation enables prenatal parenting, with implications for sensitive and devoted parental commitment.     

MARGARET THATCHER'S CHRISTIAN FAITH: A Case Study in Political Theology

Throughout the 1980s Margaret Thatcher dominated British and global politics. At the same time she maintained an active Christian faith, which she understood as shaping and informing her political choices and policies. In this article I argue that we can construct from Thatcher's key speeches, her memoirs, and her book on public policy a cultural “theo‐political” identity which guided her political decisions. Thatcher's identity was as an Anglo‐Saxon Nonconformist. This consisted of her belief in values such as thrift and hard work, care for the family and local neighbor, and charitable generosity; her belief in the renewal of the national British Christian spirit; and her notion of morality as the opportunity for free choice. Without a recognition of the centrality of her theo‐political identity, it is difficult to understand the values and beliefs which were central to her political life. The methodological issues raised by the construction of this theo‐political identity are examined in this article. The aim of the proposed methodology is to develop theological insights into a political phenomenon like Thatcher rather than make policy judgments or recommendations.
