1. Voluntary and automatic orienting of attention during childhood development
Selective attention directs cognitive resources to relevant objects or events through either voluntary (top-down) or automatic (bottom-up) control. This paper analyzes voluntary and automatic orienting of attention during childhood development. Seventy-four children (6 to 10 years old) were asked to press a key in response to a visual target presented in a p

2. 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

3. Lateral asymmetry of voluntary attention orienting
We recently demonstrated that automatic attention favors the right side of space and, in the present study, we investigated whether voluntary attention also favors this side. Six reaction time experiments were conducted. In each experiment, 12 new 18-25-year-old male right-handed individuals were tested. In Experiments 1, 2, 3 (a, b) and 4 (a, b), tasks with

4. 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

5. 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

6. Evidence for divided automatic attention
A long-standing debate in the literature is whether attention can form two or more independent spatial foci in addition to the well-known unique spatial focus. There is evidence that voluntary visual attention divides in space. The possibility that this also occurs for automatic visual attention was investigated here. Thirty-six female volunteers were tested

7. Priming effects of a peripheral visual stimulus in simple and go/no-go tasks
The early facilitatory effect of a peripheral spatially visual prime stimulus described in the literature for simple reaction time tasks has been usually smaller than that described for complex (go/no-go, choice) reaction time tasks. In the present study we investigated the reason for this difference. In a first and a second experiment we tested the particip

8. NEURAL AND COGNITIVE STUDIES OF THOUGHT DISORDER IN SCHIZOPHRENIA
Thought Disorder (TD) is one of the most striking features of schizophrenia and is manifested clinically as abnormal speech. Despite being a core feature of the illness very little is known of its pathophysiology. One model based on a series of word-pair priming studies formulates TD as a consequence of hyper activation of the semantic network. However, as w

9. Residual rightward attentional bias after apparent recovery from right hemisphere damage: implications for a multicomponent model of neglect.
Unilateral neglect may be a multicomponent attentional disorder consisting of an initial automatic orienting of attention toward the ipsilesional side and a subsequent impairment in contralesionally reorienting attention, both of which are superimposed on a generalised reduction in attention resources. It has been hypothesised that patients' ability to reori

10. Speech–sound-selective auditory impairment in children with autism: They can perceive but do not attend
In autism, severe abnormalities in social behavior coexist with aberrant attention and deficient language. In the attentional domain, attention to people and socially relevant stimuli is impaired the most. Because socially meaningful stimulus events are physically complex, a deficiency in sensory processing of complex stimuli has been suggested to contribute
