1. The effect of noise on attention and performance in reading and writing tasks
RESUMO Objetivo Investigar os efeitos de dois níveis de ruído sobre tarefas de atenção e de escrita e leitura em estudantes de três níveis de escolaridade. Método 162 sujeitos entre o 3º, 4º e 5º ano do Ensino Fundamental foram alocadas em três grupos conforme a escolaridade: controle (GC), experimental A (GEA) e experimental B (GEB). Todos os g

2. Inhibitory and attentional control: the interaction between “professional activity” and bilingualism
Abstract This study investigates the consequences of bilingualism on inhibitory and attentional control. Findings garnered from studies about the so-called bilingual advantage in such executive functions are still controversial. This investigation tested 40 (20 monolinguals and 20 bilinguals) highly-educated middle-aged (ranging from 36–58 years old) busin

3. Looming motion and visual attention
Motion perception is essential to adapt behavior in a dynamic environment. Many studies have suggested that looming motion captures attention, whereas receding motion does not, highlighting the behavioral urgency of motion perception. The present study examined whether attentional resources can be attracted by a specific directed flow in the presence of mult

4. Attentional bias modulation by reappraisal in patients with generalized anxiety disorder: an event-related potential study
Affective states influence subsequent attention allocation. We evaluated emotional negativity bias modulation by reappraisal in patients with generalized anxiety disorder (GAD) relative to normal controls. Event-related potential (ERP) recordings were obtained, and changes in P200 and P300 amplitudes in response to negative or neutral words were noted after

5. Lesions of the orbitofrontal cortex do not affect the reinforcement omission effect in rats
The reinforcement omission effect (ROE), reflected by response rates that are higher after reinforcement omission than after reinforcement delivery, has been attributed to both motivational and attentional consequences of the surprising reinforcement omission. These processes depend on the operation of separate amygdala areas and their connections with other

6. Modulation of spatial attention to visual targets by emotional environmental sounds
Previous research has shown that visual spatial attention can be modulated by emotional prosody cues, but it is not known whether such crossmodal modulation of visual attention is associated with the engagement or disengagement of attentional resources. To test this, we employed a modified spatial cueing task, where participants indicated whether a visual ta

7. Role of the amygdala in the reinforcement omission effect
The reinforcement omission effect (ROE) has been attributed to both motivational and attentional consequences of surprising reinforcement omission. Recent evidence suggests that the basolateral complex of the amygdala is involved in motivational components related to reinforcement value, whereas the central nucleus of the amygdala is involved in the processi

8. Por que locais demarcados são importantes para o aparecimento do efeito atencional automático? / Why are placeholders important to the manifestation of the automatic attentional effect?
Investigamos, no Experimento, se o estímulo precedente, que captura a atenção quando existem demarcações, deixa de capturar a atenção na ausência de demarcações por ter seu processamento filtrado precocemente. Além disso, investigamos, nos experimentos 2, 3 e 4, se alterações no fundo da tela, que gerassem maior competição no processamento dos

9. Fatores que influenciam a ocorrência do efeito atencional automático em uma tarefa de tempo de reação vai/não-vai. / Factors that influence the automatic attentional effect in a reaction time go/no-go task.
O trabalho objetivou analisar os fatores que influenciam a mobilização da atenção automática visual. Nas tarefas diárias, o Sistema Nervoso Central seleciona os estímulos mais relevantes para as tarefas. Para entender o quê influencia a mobilização atencional, conduzimos três experimentos com análise do tempo de reação a um estímulo vai em rel

10. The effects of aging and Alzheimers disease on the attencional modulation of time perception. / Modulação atencional da percepção de tempo e suas relações com o envelhecimento e a doença de Alzheimer.
Our work focused on the attentional modulation of the perception of time. Additionally, other objective was to study the effect of aging and Alzheimers disease (DA) on temporal perception. We have performed four experiments. The first and the second experiments evaluated time perception in young volunteers, by means of the reproduction and discrimination of

11. Alterações atencionais na distrofia muscular de duchenne / Attentional disturbance in Duchenne Muscular Dystrophy
OBJECTIVE: Considering the divergence in the literature regarding the base of the cognitive deficits in Duchenne Muscular Dystrophy (DMD) patients, the objective of this work was to investigate their attention performance using psychophysical tests. METHODS: 25 boys with DMD (GD) and 25 healthy boys (GC), which were 10 to 16 years old, were tested in a choic

12. Neuropsychological assessment of executive functions: developmental tends and instruments validity evidences / Avaliação neuropsicológica das funções executivas: tendências desenvolvimentais e evidências de validade de instrumentos
Executive functions (EF) are an abilities set, including selective attention, cognitive flexibility, inhibitory control, planning, monitoring and working memory, among others, whose function is to regulate and control goals oriented behaviors. There are evidences that these abilities follow distinct developmental paths, and some of them still are in full dev
