We aimed to assess whether modulation of the dorsolateral prefrontal cortex (DLFPC) with noninvasive brain stimulation, namely transcranial direct current stimulation (tDCS), modifies food craving in healthy subjects. We performed a randomized sham-controlled cross-over study in which 23 subjects received sham and active tDCS (anode left/cathode right and(More)
BACKGROUND Rett syndrome (RS) is a pervasive developmental disorder with cognitive and neuromotor impairments (including loss of handiness and loss of communicative skills). OBJECTIVE To verify whether girls with RS use their gaze intentionally, by observing their performance in three cognitive tasks: (1) verbal instruction condition (look at picture X),(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)
OBJECTIVE To verify differences in the visual scanning strategies between pervasive developmental disorders (PDD) and controls when they are observing social and non-social pictures. METHOD PDD group (PDDG) comprised by 10 non-retarded subjects (age from 4 to 41) and age-matched control group (CG). Nine social pictures with human beings (including two(More)
The cognitive model of reading comprehension (RC) posits that RC is a result of the interaction between decoding and linguistic comprehension. Recently, the notion of decoding skill was expanded to include word recognition. In addition, some studies suggest that other skills could be integrated into this model, like processing speed, and have consistently(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)
Analysis of eye movement patterns during tracking tasks represents a potential way to identify differences in the cognitive processing and motor mechanisms underlying reading in dyslexic children before the occurrence of school failure. The current study aimed to evaluate the pattern of eye movements in antisaccades, predictive saccades and visually guided(More)
Eye movements and scan patterns in mental rotation tasks Abstract The purpose of this paper is to identify the strategies used on mental rotation tasks by analyzing ocular movements. The performance of 40 participants on comparison of pairs of three-dimensional objects, rotated on the y-axis, from 0 o to 180 o was analyzed. An eye-tracking computerized(More)
The aim of this study was to verify which stages of language processing are impaired in individuals with dyslexia. For this, a visual-auditory crossmodal task with semantic judgment was used. The P100 potentials were chosen, related to visual processing and initial integration, and N400 potentials related to semantic processing. Based on visual-auditory(More)
Cognitive profiles on the WAIS-III intelligence test in Brazilian adults with dyslexia Abstract The present study investigated the cognitive profiles of dyslexic adults on the Wechsler Adult Intelligence Scale (WAIS-III, Brazilian version). A total of 31 adults with dyslexia and 31 control readers who were matched by age and education level performed a(More)
