A Comparison of the Factorial Structure of DSM-IV Criteria for Generalized Anxiety Disorder Between Younger and Older Adults

The controversy concerning the validity and reliability of generalized anxiety disorder (GAD) appears to be particularly relevant in the elderly, since physical symptoms associated with GAD can readily be considered as the consequences of normal aging. This study aims to analyze the structure invariance of a questionnaire assessing the DSM-IV diagnostic criteria across samples of older adults and college students. Ninety-seven adults aged 65 or over and 130 college students completed the Worry and Anxiety Questionnaire (WAQ). The results revealed that factorial invariance could be assumed and, in addition, that scores for severity of GAD symptoms were higher in younger subjects than in older ones. The results support the applicability of DSM-IV criteria for GAD in elderly people, as the factorial structure of the WAQ was the same for this age group as for younger adults. A higher degree of GAD severity was found in the younger sample.

Cathodal tDCS of the Left Posterior Parietal Cortex Increases Proprioceptive Drift

In aiming movements the limb position drifts away from the defined target after some trials without visual feedback, a phenomenon defined as proprioceptive drift (PD). There are no studies investigating the association between the posterior parietal cortex (PPC) and PD in aiming movements. Therefore, cathodal and sham transcranial direct current stimulation (tDCS) were applied to the left PPC concomitantly with the performance of movements with or without vision. Cathodal tDCS applied without vision produced a higher level of PD and higher rates of drift accumulation while it decreased peak velocity and maintained the number of error corrections, not affecting movement amplitude. The proprioceptive information seems to produce an effective reference to movement, but with PPC stimulation it causes a negative impact on position.     

The Implementation of Mindfulness‐Based,Trauma‐Informed Parent Education in an Underserved Latino Community: The Emergence of a Community Workforce

In this practice‐oriented program review, a mindfulness‐based, trauma‐informed parent intervention, called Safe, Secure and Loved? (SSL), designed to strengthen nurturing parenting and children's resilience, was implemented in an underserved Latino community. Across 5 years, a volunteer community workforce of promotoras transformed an academic–community research partnership into a community‐led program partnership and established sustainable agency parent education programming. To better understand this transformation, we used a modified implementation science (IS) framework to structure interviews from members of the academic–community research partnership. Findings suggest that the commitment and cultural expertise of the volunteer community workforce acted as the major leadership drivers to create the community‐led program partnership. Employing mindfulness‐based, trauma‐informed parent education designed to promote nurturing parenting and children's resilience may be an effective training model to engage and mobilize a volunteer community workforce from an underserved community.     

Pre-training to find a hidden platform in the Morris water maze can compensate for a deficit to find a cued platform in a rat model of Parkinson's disease

The bilateral intranigral infusion of 1 micromol 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) in adult male Wistar rats caused a specific and partial loss of substantia nigra pars compacta (SNc) dopamine neurons, a partial depletion of striatal dopamine, and a deficit to learn the intra-maze cued version of the Morris water maze. Pre-training the SNc rats in the spatial version of the water maze or simply maintaining the animals on the water maze platform reversed this deficit. This improvement was even observed when the order of the extra-maze cues presented to the rats during pre-training of the spatial version was changed during training of the intra-maze cued version. However, this deficit was not reversed either by maintaining the animals on the platform if the spatial cues were surrounded and covered with a curtain or by swimming sessions in the maze without the escape platform and the curtain. These findings suggest that none of the following elements alone, learned during the spatial task pre-training, could help SNc rats learn the intra-maze cued task: improvement of swimming skills or knowledge of the existence of the escape platform; distance between the platform and the border of the pool; location of a particular extra-maze cue; relations among extra-maze cues. However, the simultaneous presence of the escape platform and extra-maze cues (irrespective of their relational configuration) during the pre-training sessions proved to be necessary for this improving effect to occur.     

Friendships of older men and women: exchange patterns and satisfaction

In this study we examined the relation between perceived equity of exchanges and friendship satisfaction for a sample of 110 older men and women. Respondents were interviewed concerning their relationship with their best friend and one other friend in their support network. Perceived equity was a significant predictor of friendship satisfaction only in the case of the other friend. In addition, results showed that men were involved in more equitable friendships than were women. Discussion focuses on the importance of equity consideration and gender differences in the friendships of older adults.     

Focusing attention on overlapping and non-overlapping figures with subjective contours

In a series of five experiments we investigated whether observers could focus attention on a restricted visual area that was demarcated by Kanizsa-like subjective contours, and whether this effect also occurred in the case of overlapping figures. The task was a simple reaction time to a luminance increment and the basic finding was that reaction time was faster when the imperative stimulus fell inside the focus of attention than when it fell outside. The first two experiments showed that the extent of the attentional focus could be adapted to a region that was demarcated by subjective contours, thus extending the results of previous studies that used regions demarcated by real contours. The last three experiments showed that, regardless of the type of margins, focusing was more efficient for the figure that was perceived as lying in front in a pair of overlapping figures.

Teaching and Cultural Otherness

This work focuses on the relational dimension of the encounter between teacher and students meant as a structural element for teaching practice. By using theoretical group-analytical and anthropo-analytical coordinates, the authors psychodynamically problematize some relational conditions that may influence learning. This research concentrates on the circumstances that limit and allow the birth of a group arrangement capable to learn from experience, rather than on a perspective to teach-learn in a perfect agreement with planning. Intercultural education is pointed out and located as a horizon and ideal term to guide educational practice.
