BACKGROUND Nocturnal leg cramps are a common health problem in the ambulatory setting. Our objective was to evaluate the efficacy of magnesium in the treatment of nocturnal leg cramps. METHODS Our study was a crossover randomized double-blind placebo-controlled trial. We included patients from a large university-based ambulatory clinic in Buenos Aires,(More)
We report one study investigating how persons are categorized when the targets are presented with contextual cues. Using photos of either persons in occupational clothing and in occupational contexts or photos of college students and without distracting stimuli, the response times to verify various group memberships were tested, with the underlying interest(More)
A model of social perception is presented and tested. The model is based on cognitive neuroscience models and proposes that the right cerebral hemisphere is more efficient at processing combinations of features whereas the left hemisphere is superior at identifying single features. These processes are hypothesized to produce person and group-based(More)
Two experiments tested the hypothesis that social perception recruits distinct limited-capacity processing resources that are distinguished by the cerebral hemispheres. To test this hypothesis, social perception efficiency was assessed after relevant hemispheric processing resources were depleted. In Experiment 1 prime faces were unilaterally presented for(More)
The limited capacity of face perception resources in the left cerebral hemisphere was examined using a sex categorization task. One study tested the hypothesis that sex categorization is impeded whenever feature extraction resources in the left hemisphere are simultaneously being utilized by another task. This hypothesis was tested by presenting prime faces(More)
Natural language interfaces to databases are considered one of the best alternatives for final users who wish to make complex, uncommon and frequent queries, which is a very common need in organizations. The use of this type of interfaces has been very limited, due to their limited publicizing and the complexity to adapt them to users' needs, and because(More)
The revised hierarchical model (RHM) of bilingual language processing posits independent word form representations for the dominant language (L1) and the nondominant language (L2), facilitated translation from L2 words to L1 words, access to common concepts for L1 and L2, and stronger activation of concepts for L1 than for L2. Spanish-English and(More)
Predictions derived from models of cultural pluralism and cultural assimilation were tested. Previous research has shown that highlighting differences between ethnic groups, in conjunction with self-focus, can reduce prejudice. The presented research tested the following questions: (a) does highlighting differences function to reduce prejudice between(More)
Prejudice is generally thought to derive from learned, emotion-laden experiences. The mechanisms underlying the formation of prejudice over time, however, remain unknown. In the present research, we proposed and tested hypotheses regarding prejudice formation derived from research on memory consolidation and social perception. We hypothesized that(More)
We investigated the effect of how one might expect one's group to be viewed by a dominant outgroup (i.e., metastereotypes) on employability beliefs of members of disadvantaged groups. Based on the extensive literature on stereotype threat, we hypothesized that activating negative metastereotypes would undermine employability beliefs of members of(More)
