Parental socioeconomic status and the neural basis of arithmetic: differential relations to verbal and visuo‐spatial representations

We examined the relation of parental socioeconomic status (SES) to the neural bases of subtraction in school‐age children (9‐ to 12‐year‐olds). We independently localized brain regions subserving verbal versus visuo‐spatial representations to determine whether the parental SES‐related differences in children's reliance on these neural representations vary as a function of math skill. At higher SES levels, higher skill was associated with greater recruitment of the left temporal cortex, identified by the verbal localizer. At lower SES levels, higher skill was associated with greater recruitment of right parietal cortex, identified by the visuo‐spatial localizer. This suggests that depending on parental SES, children engage different neural systems to solve subtraction problems. Furthermore, SES was related to the activation in the left temporal and frontal cortex during the independent verbal localizer task, but it was not related to activation during the independent visuo‐spatial localizer task. Differences in activation during the verbal localizer task in turn were related to differences in activation during the subtraction task in right parietal cortex. The relation was stronger at lower SES levels. This result suggests that SES‐related differences in the visuo‐spatial regions during subtraction might be based in SES‐related verbal differences.     

Amygdala or hippocampus inactivation after retrieval induces temporary memory deficit

The hypothesis that memory is stored through a single stage of consolidation that results in a stable and lasting long-term memory has been challenged by the proposition that reactivation of a memory induces reconsolidation of the memory. The reconsolidation hypothesis is supported by evidence that, under some conditions, post-retrieval treatments affecting amygdala and hippocampus functioning impair subsequent retention performance. We now report that repeated retention testing attenuates the performance impairment induced by post-retrieval reversible inactivation of the amygdala and hippocampus of rats induced by tetrodotoxin. These findings challenge the reconsolidation hypothesis and suggest that the post-retrieval retention performance impairment is best explained as due to temporary retrieval failure.     

Evaluation of school-based child sexual abuse prevention program

The aim of the present work is to evaluate the efficacy of a program entitled "Prevention of child sexual abuse" the first structured program in Spain designed to prevent such risks. With this purpose, we carried out a study of 382 minors with ages ranging between 8 and 12 years. The result s show that the program has a very positive impact, increasing the awareness of the minors about this type of risk and improving their skills for coping with a possible event of sexual abuse. The efficacy of the program is also apparent, at the level of secondary prevention, in that it increased the likelihood that the children would reveal such events. Finally, exploration of the possible adverse effects of the program showed that the negative effects observed by parents and educators are negligible.     

Theme Articles: Mujerismo and The Two Kin‐doms: Distinction and Reconciliation

Abstract : The theological ethics underlining mujeristas' theological praxis and Luther's Two Kingdoms doctrine may seem to be contradictory to some. Mujerista theology calls for active engagement in the public sphere. Despite its utilization to the contrary, Luther's Two Kingdoms doctrine calls for that same active engagement of the Christian in civic matters. As a Lutheran Latina, I posit that the theological ethics of mujeristas and Luther's Two Kingdoms are distinct but reconcilable.     

Theory and research in Mexican social psychology

Social psychology in Mexico has its roots in the early 20th century as a field with the objective of recognizing the ethnic character of its people. Influences from the United States and Europe, combined with indigenous thinkers gave way to the growth of a psychological, a sociological and a cultural perspective. In addition, as it occurs in spaces were smooth and amiable interpersonal relationships are paramount, and social, economic and political problems thrive, a unique applied tradition has emerged. In order to offer a concise but at the same time broad view of Mexican social psychology, theory and research trends, both classical and contemporary are reviewed, offering examples of prevailing methodologies and findings.     

Estructura morfológica y recuperación léxica

Resumen

El objetivo principal de esta investigación es el de contribuir a un mayor conocimiento del papel que desempeña la estructura morfológica de las palabras en la organización del léxico interno y, por consiguiente, en las estrategias que emplean los sujetos para acceder a la representación mental de las palabras. Más en concreto, se trata de ver cuál es la relación existente entre la representación de la forma base de una palabra (por ej., flor) y la de formas derivadas de la misma (por ej., florero, florecer, florido) de cara a una posible simplificación del inventario mental de entradas léxicas.

Se han realizado tres experimentos, basados en una tarea de decisión léxica y en la utilización de la técnica de «priming» o presentación previa de un supuesto elemento facilitador del reconocimiento de cada estímulo. Se midió la latencia de respuesta para clasificar los estímulos como palabras o no-palabras del idioma. Los dos primeros experimentos se efectuaron bajo la modalidad visual de reconocimiento y el tercero, bajo la modalidad auditiva. En todos los casos, las comparaciones relevantes se establecen entre los TRs correspondientes a una misma palabra en condiciones experimentales diferentes: según vaya precedida por sí misma, o por una relacionada morfológicamente, o cuando no vaya precedida ni por sí misma ni por otra relacionada (condición de control).

Los resultados obtenidos bajo las dos modalidades perceptivas son coincidentes y ponen de manifiesto que: 1) se da un efecto de facilitación en el reconocimiento, tanto al presentar una palabra precedida por sí misma (repetición) como al presentarla precedida por otra relacionada morfológicamente; 2) el efecto de facilitación por repetición es significativamente superior al de facilitación por relación morfológica; y 3) dentro de este último no aparecen diferencias significativas entre la facilitación de la forma base por la derivada y la de ésta por aquélla.

Estos resultados se interpretan a la luz de los distintos modelos propuestos acerca de la representación léxica. Sin que sean cruciales para decidirse por uno de ellos en contra de los otros, sí que parecen apoyar la existencia de un código de representación abstracto que aglutina familias de palabras relacionadas morfológicamente en torno a una misma entrada léxica. En cualquier caso, y aun suponiendo que hubiera entradas léxicas distintas para cada forma particular, sería preciso postular algún mecanismo adicional que diera cuenta del papel que desempeña la información morfológica en la organización general del léxico interno.     

Perversion from the medical-legal perspective

Abstract

The medical-legal view of perversion is strictly concerned with the sexual aspect. This is the result of a controversial historical process full of moralism with respect to sexuality. Psychoanalysis questions this reductionist view, offering itself as instrument of special importance in the characterization of perversion as a complex of structures in human beings.

Alves KC und Prado de Sousa S. Perversion aus der medizin-rechtlichen Perspektive

Die medizin-rechtliche Sicht der Perversion ist strikt mit dem sexuellen Aspekt befaßt. Dies ist das Ergebnis eines kontrovers historischen Prozesses, der ganz mit Moralismus im Hinblick auf Sexualität angefüllt ist. Psychoanalyse stellt diese reduktionistische Sicht in Frage und bietet sich selbst als Instrument von besonderer Bedeutung an, die Perversion als einen Komplex von Strukturen bei Menschen zu charakterisieren.

A Comparison of Modalities in Modeling

Organizational display rules (e.g., “service with a smile”) have had mixed relationships with employee emotional labor—either in the form of “bad faith” surface acting (suppressing or faking expressions) or “good faith” deep acting (modifying inner feelings). We draw on the motivational perspective of emotional labor to argue that individual differences in customer orientation will directly and indirectly relate to these acting strategies in response to display rules. With a survey of more than 500 working adults in customer contact positions, and controlling for affective disposition, we find that customer orientation directly increases “good faith” acting while it moderates the relationship of display rules with “bad faith” acting.     

Examining Spouse/Partner Presence as a Moderator in the Relationship Between Mental Health Symptoms and Alcohol Use in OEF/OIF Veterans

Veterans from the conflicts in Afghanistan (Operation Enduring Freedom; OEF) and Iraq (Operation Iraqi Freedom; OIF) have reported elevated rates of alcohol consumption, and greater depression and posttraumatic stress disorder (PTSD) symptoms are associated with increased alcohol use. Presence of a spouse/partner, which has been associated with reduced drinking, may buffer the relationship between mental health symptoms and alcohol consumption. To examine this hypothesis, the current study utilized baseline survey data from OEF/OIF veterans (N = 325) enrolled in a brief alcohol intervention. Spouse/partner presence moderated the relationship between depression symptoms and alcohol consumption such that depression was positively associated with drinking for veterans without a spouse/partner. Exploratory analyses indicated that the relationship between depression and alcohol use may be particularly salient for veterans without a spouse/partner and a lower number of deployments. Spouse/partner presence did not moderate the relationship between PTSD symptoms and alcohol consumption. Implications of the findings are discussed.     

Against libertarianism

The so-called Mind argument aims at the conclusion that agents act freely only if determinism is true. The soundness of this argument entails the falsity of libertarianism, the two-part thesis that agents act freely, and free action and determinism are incompatible. In this paper, I offer a new formulation of the Mind argument. I argue that it is true by definition that if an agent acts freely, either (i) nothing nomologically grounds an agent’s acting freely, or (ii) the consequence argument for incompatibilism is unsound. I define the notion of nomological grounding, and argue that unless an agent’s acting freely is nomologically grounded, unacceptable consequences follow. I then argue that if agents act freely and the consequence argument is sound, a vicious regress ensues. I conclude by considering the libertarian’s dialectical options.
