1. A program of physical activity improves gait impairment in people with Alzheimer's disease
Abstract AIM This study aimed to identify the effects of aging and Alzheimer’s disease (AD) on gait parameters after a four-month period and to investigate the effects of a four-month program of physical activity, with emphasis on the cognitive components of gait during single and dual task, in people with AD. METHODS Twenty-three people with AD, divided

2. Attentional blink in children with attention deficit hyperactivity disorder
Objective:To explore the temporal mechanism of attention in children with attention deficit hyperactivity disorder (ADHD) and controls using a rapid serial visual presentation (RSVP) task in which two letters (T1 and T2) were presented in close temporal proximity among distractors (attentional blink [AB]).Method:Thirty children aged between 9 and 13 years (1

3. Aprendizagem em tarefas duais: variação de desempenho e demanda atencional / Dual task learning: variation of performance and attention demand.
O presente estudo teve como objetivo avaliar a aprendizagem em uma tarefa dual em comparação à aprendizagem de tarefas singulares e a respectiva variação de demanda atencional em função da prática. Participaram do estudo 27 estudantes universitários destros, divididos em três grupos de acordo com a tarefa praticada: prática da tarefa singular de t

4. Binding faces and names in working memory requires additional attentional resources
In this study we used the dual-task paradigm to investigate the involvement of attention in the binding of verbal and visual information in working memory. A secondary task, backward counting by threes (BCT), was performed during the retention interval of the primary recognition task based on either visual or verbal information or the binding of both. The BC

5. Acute exercise improves cognition in the depressed elderly: the effect of dual-tasks
OBJECTIVE: The goal of this study was to assess the acute effect of physical exercise on the cognitive function of depressed elderly patients in a dual-task experiment. INTRODUCTION: Physical exercise has a positive effect on the brain and may even act as a treatment for major depressive disorder. However, the effects of acute cardiovascular exercise on cogn

6. Integration of visual and verbal information in working memory / Integração de informações visuais e verbais na memória de trabalho
O paradigma de tarefas duplas foi utilizado para investigar o envolvimento da atenção na conjunção da informação verbal e visual na memória de trabalho, e o papel específico desses componentes quando integrados. Em dois experimentos os sujeitos (33) memorizaram seqüências de Faces, Nomes, ou Conjunções face-nome. No experimento 1 essas condiçõe

7. Efeitos de um treinamento em condições de dupla-tarefa sobre o desempenho motor e habilidade de dividir a atenção em pacientes com doença de Parkinson. / Effects of training in dual-task situations on the motor performance and the abillity to divide attention in subjects with Parkinsons Disease
The Parkinsons Disease (PD) is one of the degenerative disorders of the Central Nervous System (CNS) that has been greatly discussed both in clinical and experimental researches. Its major motor symptoms are tremors, rigidity or muscle stiffness, bradykinesia and postural instability. Not less important, subjects with PD may suffer from emotional changes and

8. Comparação entre os efeitos do treino motor isolado e do treino motor em condição de tarefa dupla, sobre a marcha e a atenção, em idosos saudáveis e pacientes com doença de Parkinson / Comparison of the effects of single task and the dual-task condition motor training on the gait and on the attention in healthy elderly and Parkinsons disease patients.
A doença de Parkinson (DP) idiopática é uma patologia neurodegenerativa progressiva, caracterizada por sintomas motores como bradicinesia, rigidez muscular, tremor de repouso e instabilidade postural e sintomas não motores como alterações atentivas que influenciam o gerenciamento entre tarefas simultâneas. Mesmo no processo de envelhecimento saudável

9. Some experimental contributions to the study of the negative priming effect in selective attention tasks. / Algumas contribuições experimentais ao estudo do efeito de priming negativo em tarefas de atenção seletiva.
The development of sensitive and simple tests for the assessment of the negative priming effect has theoretical relevance to the elucidation of selective attention models, and also practical and potential clinical implications. The negative priming effect has been regarded as an index of inhibitory attentional processing and was proposed for the detection of

10. Letter recognition reveals pathways of second-order and third-order motion
How are second-order (texture-defined) and third-order (pattern-tracking) motions processed in our brains? As shown here in the context of an ambiguous motion task involving a nominal second-order stimuli first devised by Werkhoven et al., [Werkhoven, P., Sperling, G. & Chubb, C. (1993) Vision Res. 33, 463–485.], the observers fell into two distinct g

11. Evidence for Processing Stages in Skill Acquisition: A Dual-Task Study
We investigated the changes of resource demand during the acquisition of a sensorimotor skill, namely the tracking of a visual target under reversed visual feedback. This acquisition task was performed alone or concurrently with one of four manual reaction-time tasks as loading tasks, designed to tap different computational resources. As expected, we found t

12. Modulation of long-range neural synchrony reflects temporal limitations of visual attention in humans
Because of attentional limitations, the human visual system can process for awareness and response only a fraction of the input received. Lesion and functional imaging studies have identified frontal, temporal, and parietal areas as playing a major role in the attentional control of visual processing, but very little is known about how these areas interact t
