Absence of placeholders abolishes exogenous attention effect in a peripheral cueing procedure
(Scientific & Academic Publishing CoRosemead, 2013)
Most studies of exogenous visuospatial attention use placeholders indicating the regions where the stimuli appear on the screen. Preliminary results from our laboratory provided evidence that the attentional effect is more ...
An Attentional Model for Autonomous Mobile Robots
The increase of applications that use autonomous robots has endowed them with a high number of sensors and actuators that are sometimes redundant. This new highly complex systems and the type of environment where they are ...
The reward-attention circuit model: nicotine's influence on attentional focus and consequences on attention deficit hyperactivity disorder
(Elsevier Science Bv, 2017-06-14)
In this work we investigate the influence that nicotine exerts on attention focusing, modeling the coupling of reward and thalamocortical circuits. Each neuron in the neural networks that replicate such circuits is described ...
Effect of phychostimulants on distinct attentional parameters in attentional deficit/hyperactivity disorder
Although there is extensive literature about the effects of stimulants on sustained attention tasks in attentional deficit/hyperactivity disorder (ADHD), little is known about the effect of these drugs on other attentional ...
Effect of Psychostimulants on Distinct Attentional Parameters in Attentional Deficit/Hyperactivity Disorder
(Sociedad de Biología de Chile, 2004)
Irrelevant stimulus processing in ADHD: catecholamine dynamics and attentional networks
(Frontiers Media, 2014)
A cardinal symptom of attention deficit and hyperactivity disorder (ADHD) is a general distractibility where children and adults shift their attentional focus to stimuli that are irrelevant to the ongoing behavior. This ...
Endogenous-like orienting of visual attention in rats
(SPRINGER HEIDELBERG, 2011)
This study investigated the orienting of visual attention in rats using a 3-hole nose-poke task analogous to Posner, Information processing in cognition: the Loyola Symposium, Erlbaum, Hillsdale, (1980) covert attention ...
Which factors are important for crossmodal attentional effect?
Some results in the literature suggest that crossmodal attention is very sensitive to the features of the experimental protocol. The current work examined the possible contribution of the asynchrony between the onset of ...
Evidence for divided automatic attention
(Associação Brasileira de Divulgação Científica, 2008)
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 ...
A study on language, attention and school practices: inattention or cycling focus attention
(Editora UnisinosSao LeopoldoBrasil, 2011)
