Several studies have reported that transcranial direct current stimulation (tDCS), a non-invasive method of neuromodulation, enhances some aspects of working memory in healthy and Parkinson disease subjects. The aim of this study was to investigate the impact of anodal tDCS on recognition memory, working memory and selective attention in Alzheimer disease(More)
Food craving can be defined as the "urge to eat a specific food". Previous findings suggest impairment of inhibitory control, specifically a regulatory deficit in the lateral prefrontal circuitry that is associated with a compulsion for food. As demonstrated by three previous studies, bilateral transcranial direct current stimulation (tDCS) of the(More)
The analysis of cognitive processes underpinning reading and writing skills may help to distinguish different reading ability profiles. The present study used a Brazilian reading and writing battery to compare performance of students with dyslexia with two individually matched control groups: one contrasting on reading competence but not age and the other(More)
traditional paper-and-pencil versions have been standardized with a sample of 1158 deaf students. This study provides preliminary validation of three out of the six computerized battery tests with hearing children. By comparing data obtained with the computerized tests to data obtained with the paper-and-pencil tests, the study found out that they are(More)
UNLABELLED Individuals with Down syndrome (DS) tend to have impaired verbal short-term memory (STM), which persists even when visual support is provided for carrying out verbal tasks. OBJECTIVE The current study aims to investigate whether visuospatial support, rather than just visual, can compensate for verbal STM deficits in these individuals. The(More)
BACKGROUND the working memory is a cognitive skill that contributes to adequate development of language and to the acquisition of reading and writing. A consistent evaluation of the working memory in pre-school and basic school children demonstrates to be important for the early identification of possible learning impairments. AIM to evaluate the(More)
OBJECTIVE The aim of this study was to assess the frequency of depressive symptoms and to evaluate cognitive performance of institutionalized versus non-institutionalized elderly subjects and to compare the effect of institutionalization and participation in the institution's activity programs on their cognitive performance. METHOD A group of 120 elderly(More)
PURPOSE To analyze eye movements in asymmetric visual search using the task of normal and mirrored position letters. To evaluate the effect of familiarity and stimulus features. METHODS Eighty-three university students with normal or corrected-to-normal vision were asked to search for a letter in inverted position to the letters in a group of either(More)
