New insights on sensorimotor integration: from hand action to speech perception

In the last two decades the integrative role of the frontal premotor cortex (a mosaic of agranular/disgranular areas lying in front of the primary motor cortex) have been more and more elucidated. Among its various functions, sensorimotor transformation, and action representation storage, also for nonstrictly motor purposes, are the most intriguing properties of this region, as shown by several researches. In this article we will mainly focus on the ventro-rostral part of the monkey premotor cortex (area F5) in which visual information describing objects and others' acting hands are associated with goal-directed motor representations of hand movements. We will describe the main characteristics of F5 premotor neurons and we will provide evidence in favor of a parallelism between monkeys and humans on the basis of new experimental observations. Finally, we will present some data indicating that, both in humans and in monkeys, action-related sensorimotor transformations are not restricted to visual information but concern also acoustic information.     

Same kinematics but different objects during action observation: Detection times and motor evoked potentials

Motor resonance refers to the fact that an observed action is online subliminally reenacted. The aim of the present paper was to verify if, on equal terms of kinematics, the to-be-grasped object's intrinsic properties are influencing the observers' motor behaviour. A detection time and a single pulse transcranial magnetic stimulation experiment were performed to verify the effects of a change of object's intrinsic properties artificially made on a video showing a grasping action. In particular, the object substituting the original one was not graspable by the showed movement. Results indicated an influence of object's intrinsic properties: Detection times were delayed and motor evoked potentials were reduced when the movement shown was not suitable to grasp the object. These results are interpreted as an evidence that during grasping action observation the motor system of the observer is influenced not only by the seen movements but also by the to-be-grasped object.     

From victimhood to empowerment: Muslim women's narratives in the Shari'a courts of Jerusalem and Taibe

This study features the voices of women who sued their husbands in the Shari'a courts, revealing the empowerment that resulted from learning their legal rights. The stories of some two hundred Palestinian Muslim women who appealed to the Shari'a courts in Jerusalem and Taibe during the years 2000–2003 formed the basis of this study. The women came to the courts to claim material support (nafaqa) from their husbands and to demand child support (hadane). Four major reasons why these women sued their husbands in court emerged from their stories, revealing familial, social, economic and even political circumstances that impinged on their lives.     

Fertility Behavior and Psychological Stress: The Mediating Influence of Gender Norm Beliefs Among Egyptian Women

The influence of gender norms on women's family planning experiences is a finding that cuts across numerous studies included in Family Health International's multi-country Women's Studies Project. This paper explores findings from one of these studies on the mediating influence of beliefs about gender norms on the relationship between fertility behavior and psychological well-being. Using cross-sectional survey data from 4,908 Egyptian women, hierarchical multiple regression models were tested with depression and anxiety as the dependent variables. Independent variables included three demographic variables, two measures of beliefs about gender norms developed from survey items using exploratory factor analytic techniques, and two fertility behavior variables—use of family planning and number of children. Gender norm beliefs predicted both anxiety and depression. The statistical analyses demonstrated a separate effect of family planning use on anxiety, independent of gender norm beliefs, but the effect of family planning behaviors on depression disappeared when gender norms beliefs were included in the regression model, which indicates a mediating effect of gender norm beliefs. Although cross-sectional data do not allow for the determination of causality among the three types of variables, a conceptual framework is offered for the possible causal mechanisms for the identified relationships.     

The influence of dimensionality on eye fixations.

Eye fixation patterns were explored for sixty adult subjects, each of whom viewed one of three stimuli, either in a three-dimensional model format or in a two-dimensional photographic format. The stimuli consisted of one symmetrical and two asymmetrical color representational drawings displayed in the form of a photograph or of a model. Total fixation times (in ms) were computed for seven portions of each stimulus: top, bottom, left, right, foreground, middle ground, and background. Results indicated that for all stimuli, subjects viewing the 3-D model spent significantly more time fixating the foreground and significantly less time fixating the background than subjects viewing the 2-D photograph. For the two asymmetrical stimuli subjects in the two groups differed significantly in their fixation patterns for the left/right variables. It was concluded that eye fixation patterns vary as a function of dimensionality.
