Individual differences in executive function partially explain the socioeconomic gradient in middle‐school academic achievement

Children from families with low socioeconomic status (SES) earn lower grades, perform worse on achievement tests, and attain less education on average than their peers from higher‐SES families. We evaluated neurocognitive mediators of SES disparities in achievement in a diverse sample of youth whose data were linked to administrative records of performance on school‐administered tests of 7th grade reading and math proficiency (N = 203). We used structural equation modeling to evaluate whether associations between SES (measured at ages 8–9) and achievement (measured at age 13) are mediated by verbal ability and executive function (measured at age 10), a suite of top‐down mental processes that facilitate control of thinking and behavior. Children from relatively higher‐SES families performed better than their lower‐SES peers on all neurocognitive and achievement measures, and SES disparities in both reading and math achievement were partially mediated by variation in executive function, but not verbal ability. SES disparities in executive function explained approximately 37% of the SES gap in math achievement and 17% of the SES gap in reading achievement. Exploratory modeling suggests that SES‐related variation in working memory may play a particularly prominent role in mediation. We discuss potential implications of these findings for research, intervention programming, and classroom practice.     

L’adhésion des populations immigrantes à la valeur de l’autonomie véhiculée en santé publique

Autonomy, a basic ethical value in public health, is regularly put under pressure by the demands of empowerment, rights of individuals and healthy communities. This article describes the results of a study about the support of non-immigrants and immigrants subjects (n?=?137) from the Montreal area on the value of autonomy conveyed in six public health programs. The results indicate that non-immigrants Quebecers and longstanding immigrants differ from recent immigrants concerning activities about commitment of fathers, poverty families, screening for sexually transmitted diseases and treatment of tuberculosis.     

“Hearts with one purpose alone”? Thinking personal sustainability in social movements

While attention is now being paid to emotions and personal sustainability in social movements, relatively little attention has been paid to difference between social movement situations or broader cultural contexts. This paper locates the question in the broader history of thinking about ordinary people's political engagement since the French Revolution. It explores various literatures relating to the topic, arguing that emotional sustainability is only one aspect of personal sustainability in social movements. Using the example of WB Yeats' response to the 1916 Easter Rising, it highlights the importance of locating this in place, time and culture. The paper offers a typological approach as a counter-strategy to the assumption of uniformity, focussing on difference in social situation, organising contexts and background cultures.     

Interpreting claims in offender profiles: the role of probability phrases,base‐rates and perceived dangerousness

Offender profilers use verbal and numerical probability expressions to convey uncertainty surrounding claims made about offender's characteristics. No previous research has examined how these expressions might affect the recipient's interpretation of the information. Seventy participants completed an online questionnaire and results showed a diverse range of interpretations of these uncertainty expressions. Moreover, characteristic base‐rates and dangerousness affected the perceived likelihood of the profiling claim, such that increased base‐rates and perceived dangerousness resulted in an increased perception of the claim being likely. Perceived likelihoods also depended on the framing of characteristics as well as the framing of the claim itself. Finally, where claims involved presenting a characteristic qualified by a low probability these claims were interpreted as more likely than not to be present. These findings have practical implications for profilers and more general theoretical implications for the study of risk perception. Copyright © 2008 John Wiley & Sons, Ltd.     

Impact of Behavioral Inhibition and Parenting Style on Internalizing and Externalizing Problems from Early Childhood through Adolescence

Behavioral inhibition (BI) is characterized by a pattern of extreme social reticence, risk for internalizing behavior problems, and possible protection against externalizing behavior problems. Parenting style may also contribute to these associations between BI and behavior problems (BP). A sample of 113 children was assessed for BI in the laboratory at 14 and 24 months of age, self-report of maternal parenting style at 7 years of age, and maternal report of child internalizing and externalizing BP at 4, 7, and 15 years. Internalizing problems at age 4 were greatest among behaviorally inhibited children who also were exposed to permissive parenting. Furthermore, greater authoritative parenting was associated with less of an increase in internalizing behavior problems over time and greater authoritarian parenting was associated with a steeper decline in externalizing problems. Results highlight the importance of considering child and environmental factors in longitudinal patterns of BP across childhood and adolescence.     

A consistent way with paradox

Consideration of a paradox originally discovered by John Buridan provides a springboard for a general solution to paradoxes within the Liar family. The solution rests on a philosophical defence of truth-value-gaps and is consistent (non-dialetheist), avoids ‘revenge’ problems, imports no ad hoc assumptions, is not applicable to only a proper subset of the semantic paradoxes and implies no restriction of the expressive capacities of language.

Speech perception engages a general timer: Evidence from a divided attention word identification task

Time is essential to speech. The duration of speech segments plays a critical role in the perceptual identification of these segments, and therefore in that of spoken words. Here, using a French word identification task, we show that vowels are perceived as shorter when attention is divided between two tasks, as compared to a single task control condition. This temporal underestimation pattern is consistent with attentional models of timing and hence demonstrates that vowel duration is explicitly estimated using a central general-purpose timer.     

Medical ethics' appropriation of moral philosophy: the case of the sympathetic and the unsympathetic physician

Philosophy textbooks typically treat bioethics as a form of "applied ethics"-i.e., an attempt to apply a moral theory, like utilitarianism, to controversial ethical issues in biology and medicine. Historians, however, can find virtually no cases in which applied philosophical moral theory influenced ethical practice in biology or medicine. In light of the absence of historical evidence, the authors of this paper advance an alternative model of the historical relationship between philosophical ethics and medical ethics, the appropriation model. They offer two historical case studies to illustrate the ways in which physicians have "appropriated" concepts and theory fragments from philosophers, and demonstrate how appropriated moral philosophy profoundly influenced the way medical morality was conceived and practiced.
