Microstructural integrity of the corpus callosum linked with neuropsychological performance in adolescents

Background: Diffusion tensor imaging (DTI) has revealed microstructural aspects of adolescent brain development, the cognitive correlates of which remain relatively uncharacterized. Methods: DTI was used to assess white matter microstructure in 18 typically developing adolescents (ages 16–18). Fractional anisotropy (FA) and mean diffusion (MD) were evaluated within the splenium and body of the corpus callosum in relation to cognitive performance. Results: Visuospatial construction abilities were associated with white matter integrity in both the splenium and body of the corpus callosum, while only splenium integrity was associated with language and psychomotor function. Conclusion: Results suggest that, for typically developing adolescents, white matter coherence positively relates to visuospatial, psychomotor, and language skills. These findings may have implications for the cognitive functioning of clinical populations in which typical white matter development is altered.     

Through Thick and Thin with Ned Block: How <Emphasis Type="Italic">Not</Emphasis> to Rebut the Property Dualism Argument

In “Max Black’s Objection to Mind–Body Identity,” Ned Block seeks to offer a definitive treatment of property dualism arguments that exploit modes of presentation. I will argue that Block’s central response to property dualism is confused. The property dualist can happily grant that mental modes of presentation have a hidden physical nature. What matters for the property dualist is not the hidden physical side of the property, but the apparent mental side. Once that ‘thin’ side is granted, the property dualist has won. I conclude that although Block is wrong to think that the property dualist must argue for so-called thin mental properties, Block, and the physicalist, are able to resist property dualism. But any attempt to bolster this resistance and do more than dogmatically assert the crucial identity runs a serious risk of undermining the physicalism it is meant to save.

Event-related potentials and the decision to shoot: The role of threat perception and cognitive control

Participants played a videogame in which they were required to make speeded shoot/don’t-shoot decisions in response to armed and unarmed targets, half of whom were Black, half of whom were White. Event-related brain potentials (ERPs), recorded during the game, assessed attentional processes related to target race and object type. Early ERP components (i.e., the P200 and N200) differentiated between Black and White targets, as well as between armed and unarmed targets. Explicitly measured cultural stereotypes predicted both this racial ERP differentiation and racial bias in the game. Most importantly, the degree of racial differentiation in the early ERP components predicted behavioral bias in the videogame and mediated the relationship between cultural stereotypes and bias.     

Anorexia and the Trojan Horse: a reflexive review of written psychoanalytic encounters with anorexic patients

A selective and limited sample of clinical case studies of psychoanalytic psychotherapy with anorexic patients, focussing on the author/therapist’s experience of working with such patients, is examined. Patients’ depressive and often angry states of withdrawal, and projections, are frequently noted. A summary of more hopeful interactions, as selected from the literature reviewed, is offered. An understanding of anorexic defences is explored in relation to the ‘Trojan Horse’ mythology, in the sense that that which purports to be emotionally nourishing and sublime can be suspiciously viewed as seeking to enter and conquer, through subterfuge. Some existing challenges to traditional tenets of psychoanalytic clinical practice with anorexic patients are presented.     

Les gestes en autoconfrontation croisée : enjeux et pratiques

This article aims to show how the relationship between gestures and speech can help understand mechanisms of activity's development. In situation of self-confrontation work analysis between two workers, we study more precisely the repetition of a sweep gesture made by one of the two professionals and repeated by the other one. We argue that this type of repetition highlights development of activities mechanisms. From two extracts from a cross self-confrontation, we analyze the coordination between speech and gestures. We finally show that mismatches between gestures and speech make possible to understand development of activity of these professionals in this particular context. As a conclusion, the hypothesis that this development may be one of the origins of the transformation of action in ordinary work situations is advanced.     

Racial allyship: Novel measurement and new insights

Allies are members of an ingroup who work toward fairness for people in an outgroup. Ally behaviors include calling out discrimination and fighting for inclusion of outgroup members, and it includes public and private behaviors. As such, White allies can be an important means of reducing racism against people of color. There are few means of assessing and quantifying allyship in ingroup members, and as such, there is a need for methods for assessing allyship that can be used to better understand characteristics of allies and determine if interventions designed to reduce prejudice can improve allyship. To that end we describe an innovative scenario-based measurement technique to quantify interpersonal allyship, with White students as ingroup members (N = 987) and Black students as outgroup members (N = 61). Measurement of allyship is conducted based on participant responses to hypothetical racially-sensitive scenarios where microaggressions are occurring or likely to occur. Items were developed based focus group input, and rated by diversity experts for relevance. The factor structure of allyship items was examined by exploratory and confirmatory factor analyses. The final 10-item Interpersonal Racial Allyship Scale (IRAS) was negatively correlated to 3 measures of racist attitudes and 1 measure of microaggressive behaviors, and it was positively correlated to 2 measures of outgroup liking. It also predicted making racially supportive statements in a laboratory task. We report on characteristics of allies, noting that allied behaviors are correlated with less prejudice, stronger positive feelings toward outgroup members, and a greater likelihood of having other marginalized identities. Implications of findings and applications of the scale are discussed.     

Supremacist thinking,epistemological despair,and Christian hope

This article looks at the connection between white supremacist cults and an epistemology of despair—a view that knowledge cannot be shared or communicated between diverse people. The theology of Augustine, the fourth century African bishop, undermines the power of this epistemology by inspiring hope in dialogue as an avenue towards ending white supremacist thinking.     

Black–White mean differences in job satisfaction: A meta-analysis

Studies examining Black–White mean differences in job satisfaction have provided little clarity regarding whether there are meaningful differences between the two racial/ethnic groups on this job attitude. The present study sought to reconcile prior inconsistent findings via a meta-analytic synthesis of this literature (N = 753,791; K = 63 independent samples from 55 studies) and examined whether moderators explained the observed variability in effects. Using Hedges and Vevea's (1998) random-effects meta-analytic approach, we found that, on average, White workers were slightly more satisfied with their jobs than Black workers (g_corrected = .09; 95% credibility interval = −.21 to .39) and this effect was larger in more nationally representative samples (g_corrected = .24). The substantial true variability around this effect suggests the presence of moderators and the need for caution in interpreting the overall effect as it likely does not generalize across all work settings. Data collection year, geographic location within the U.S., job sector, and measure type were not found to moderate Black–White mean differences in job satisfaction. However, job complexity and sample demographic composition did significantly moderate this relationship. Our results show that the magnitude and direction of Black–White mean differences in job satisfaction are influenced by the context.     

Critical Approaches to Education in the Work of Lorenzo Milani and Paulo Freire

Paulo Freire and Lorenzo Milani are considered as key figures in a number of Southern European countries for providing signposts for a critical approach to education. In this paper I will view their ideas and biographical trajectories comparatively to glean some important insights for a critical pedagogy. The common theme throughout this comparative analysis is that of education for social justice based on critical literacy. The paper also deals with such themes as the relationship between education and politics, the relationship between education and life, the collective dimension of learning and the ability to read as well as write the word and the world.
