Physically salient stimuli, such as uniquely colored objects, seem to have an inherent power to capture our attention, but formal research on this topic has produced conflicting results and theories. Here, we review evidence that the attentional capture debate can be resolved by positing a new suppressive process. This suppressive process can occur before attentional shifting to prevent salient items from attracting attention. In the current article, we review converging evidence that salient items are suppressed to avoid attentional capture comes from studies of psychophysics, eye movements, single-unit recordings, and event-related potentials (ERPs). Crucially, the ability to inhibit salient distractors seems to be learned as participants gain experience with the simple features of the to-be-ignored stimuli.

The N2pc is routinely used as an electrophysiological index of attentional shifting. Its absence is thus taken as evidence that no shift of attention occurred. We provide evidence in contrast to this ...
Stimuli associated with reward acquire the ability to automatically capture attention. It is also the case that, with sufficient training, former targets can acquire the ability to capture attention i...
What we direct our attention to is strongly influenced by both bottom-up and top-down processes. Moreover, the control of attention is biased by prior learning, such that attention is automatically ca...
A salient, but task-irrelevant stimulus has long been known to capture attention in an automatic, involuntary manner. However, the automaticity of involuntary attention has recently been challenged. W...
Multisensory stimuli are argued to capture attention more effectively than unisensory stimuli due to their ability to elicit a super-additive neuronal response. However, behavioural evidence for enhan...
The investigators are interested in how attentional filter training/ distractor inhibition training could influence cognitive functions like working memory, executive control, problem solv...
Cognitive disorders are a major problem in patients with epilepsy. One hypothesis is that the anomalies EEGs (AIC) may be responsible for short periods of attentional fluctuations causing ...
Randomized, placebo-controlled trial of 9 sessions of computerized attentional bias training on attentional bias and on symptoms of Posttraumatic Stress Disorder.
This study is designed to investigate effects on attentional performance and motoric activity of the dietary supplement 100 mg microencapsulated glycine (Bidicin® from Biotiki®) compared...
Formal education and cognitively stimulating hobbies and profession have a protective effect against age-related cognitive decline and Alzheimer's disease. It is therefore possible that pr...
Temporary visual deficit or impaired visual processing occurring in a rapid serial visual presentation task. After a person identifies the first of two visual targets, the ability to detect the second target is impaired for the next few hundred milliseconds. This phenomenon is called attentional blink.
A pyrazine compound inhibiting SODIUM reabsorption through SODIUM CHANNELS in renal EPITHELIAL CELLS. This inhibition creates a negative potential in the luminal membranes of principal cells, located in the distal convoluted tubule and collecting duct. Negative potential reduces secretion of potassium and hydrogen ions. Amiloride is used in conjunction with DIURETICS to spare POTASSIUM loss.

An increased focus or awareness of certain stimuli over others, which influence behavior.
Solution titration in which the end point is read from the electrode-potential variations with the concentrations of potential determining ions. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
Opportunity to attain full health potential and no one is disadvantaged from achieving this potential because of their social position or other socially determined circumstance.
