Mathematical Abilities in Elementary School Children with Autism Spectrum Disorder

Although clinical practitioners often express concerns about the mathematical functioning of children with autism spectrum disorder (ASD), the field of mathematics remains a relatively unexplored topic in individuals with ASD. Moreover, research findings are fragmentary and hold inconclusive results. The present study aimed to examine whether grade 1 (aged 6–7 years) to 4 (aged 9–10 years) elementary school children with ASD scored significantly different from age‐adequate norms on mathematics. To this end, a multi‐componential approach of mathematics was used. Four domains of mathematics were assessed in 121 children with ASD: procedural calculation, number fact retrieval, word/language problems, and time‐related competences. All children attended general education classrooms, following the standard curriculum, and were coached by integrated educational services. Children with ASD showed a strength in word/language problems in second and fourth grade. There was evidence of a weakness for procedural calculation in first grade and for time‐related competences in first and third grade. In all other cases, average scores were shown. As such, results revealed a profile of strengths, average abilities, and weaknesses in mathematics and highlighted the importance of focusing on different domains of mathematics. Because a high variability in mathematical performance could be observed, we recommend an individual assessment when considering the mathematical trajectory of children with ASD.

Retrospective and prospective metacognitive judgments in rhesus macaques (Macaca mulatta)

A growing body of research suggests that some non-human animals are capable of making accurate metacognitive judgments. In previous studies, non-human animals have made either retrospective or prospective judgments (about how they did on a test or how they will do on a test, respectively). These two types of judgments are dissociable in humans. The current study tested the abilities of two rhesus macaque monkeys to make both retrospective and prospective judgments about their performance on the same memory task. Both monkeys had been trained previously to make retrospective confidence judgments. Both monkeys successfully demonstrated transfer of retrospective metacognitive judgments to the new memory task. Furthermore, both monkeys transferred their retrospective judgments to the prospective task (one, immediately, and one, following the elimination of a response bias). This study is the first to demonstrate both retrospective and prospective monitoring abilities in the same monkeys and on the same task, suggesting a greater level of flexibility in animals’ metacognitive monitoring abilities than has been reported previously.     

Importance models of the physical self: Improved methodology supports a normative‐cultural importance model but not the individual importance model

We examine theoretical and methodological issues associated with the roles of individual and group‐normative importance in self‐esteem determination. Critical issues include multicollinearity among the physical self‐subdomains, which may have affected previous results, and the need for a multidimensional perspective on importance models. We apply state‐of‐the‐art methodologies, including exploratory structural equation modelling and the product‐of‐indicators approach to latent interactions. Positive interactions would be required to support the individually importance‐weighted average model, but none were observed in the multidimensional model estimated on the full sample. Nonetheless, some interaction effects were found in the country‐specific version of the model. Rather, we found support for the alternative group importance‐weighted average model. We conclude that domain‐specific self‐concepts are weighted differently and thus differentially affect self‐esteem, but these weights do not seem to depend on individual differences in importance. Although awaiting confirmation from further studies, our results suggest the idea that individuals use mainly normative importance processes based on cultural factors in weighting each domain‐specific component of self‐concept.

Bayes Factors Have Frequency Properties—This Should Not Be Ignored: A Rejoinder to Morey,Wagenmakers, and Rouder

Guiding trustful behavior: The role of accessible content and accessibility experiences

Trust has been identified as a key ingredient to the prosperity of close relationships, organizations, and societies. While research mainly focused on the antecedents and consequences of trust, much less is known about how individuals assess whether there are enough reasons to warrant trustful action. Two experiments explored the how and when of this assessment, suggesting that antecedents may not only be integrated as content information per se (as generally assumed), but in a feeling‐based summary form. Specifically, our results show that the ease or difficulty associated with the identification of antecedents to trust may guide trustful behavior. Furthermore, it is shown that such a feeling‐based influence is particularly likely to occur in conditions of personal certainty. Together these results extend prior research in the domains of trust and economic games, and further attest to the fundamental role cognitive feelings play in social life.

Academic self‐concept and academic achievement: Relations and causal ordering

Background. A positive self‐concept is valued as a desirable outcome in many disciplines of psychology as well as an important mediator to other outcomes. Aims. The present review examines support for the reciprocal effects model (REM) that posits academic self‐concept (ASC) and achievement are mutually reinforcing, each leading to gains in the other – and its extension to other achievement domains. Method. We review theoretical, methodological, and empirical support for the REM. Critical features in this research are a theoretical emphasis on multidimensional perspectives that focus on specific components of self‐concept and a methodological focus on a construct validity approach to evaluating the REM. Results. Consistent with these distinctions, REM research and a comprehensive meta‐analysis show that prior ASC has direct and indirect effects on subsequent achievement, whilst the effects of self‐esteem and other non‐academic components of self‐concept are negligible. We then provide an overview of subsequent support for the generality of the REM for: young children, cross‐cultural, health (physical activity), and non‐elite (gymnastics) and elite (international swimming championships) sport. Conclusion. This research is important in demonstrating that increases in ASC lead to increases in subsequent academic achievement and other desirable educational outcomes. Findings confirm that not only is self‐concept an important outcome variable in itself, it also plays a central role in affecting other desirable educational outcomes. Implications for educational practice are discussed.     

Tribute to Don S. Browning (1934–2010)

This tribute adapts words originally written to honor Don S. Browning, one of the foremost pastoral and practical theologians and ethicists of his time, on the occasion of his death on June 3, 2010. The tribute appeared in the funeral worship bulletin on June 10, 2010 at Hyde Park Union Church in Chicago and was revised for a newsletter of a major educational institution with which he had many significant relationships and responsibilities (The Disciples Divinity House of the University of Chicago Bulletin 80, no. 1 (Spring/Summer 2010); used with permission). Although we embellished the tribute slightly, we did not change its main intent: It captures the remarkable depth and breath of Browning’s scholarly achievement, the mark he made on public and academic discussion, and the extent to which he is missed by his colleagues, friends, and family.
