A small but growing neuroimaging literature has begun to examine the neural mechanisms underlying the difficulty that substance-use dependent (SUD) groups have with ignoring salient, drug-related stimuli. Drug-related attentional bias appears to implicate the countermanding forces of cognitive control and reward salience. Basic cognitive neuroscience research suggests that ignoring emotionally ...

Successful goal-directed visual behavior depends on efficient disengagement of attention. Attention must be withdrawn from its current focus before being redeployed to a new object or internal process. Previous research has demonstrated that occupying cognitive processes with a secondary cellular phone conversation impairs attentional functioning and driving behavior. For example, attentional p...

The mechanisms by which aging and other processes can affect the structure and function of brain networks are important to understanding normal age-related cognitive decline. Advancing age is known to be associated with various disease processes, including clinically asymptomatic vascular and inflammation processes that contribute to white matter structural alteration and potential injury. The ...

The present research explored rewarding bias and attentional deficits in Internet addiction (IA) based on the IAT (Internet Addiction Test) construct, during an attentional inhibitory task (Go/NoGo task). Event-related Potentials (ERPs) effects (Feedback Related Negativity (FRN) and P300) were monitored in concomitance with Behavioral Activation System (BAS) modulation. High-IAT young participa...

Many previous studies reported that the hyperpolarization of cortical neurons following cathodal stimulation (in transcranial direct current stimulation) has resulted in cognitive performance degradation. Here, we challenge this assumption by showing that cathodal stimulation will not always degrade cognitive performance. We used an attentional load paradigm in which irrelevant stimuli are proc...

objective: attention is an important factor in information processing; obsessive- compulsive disorder (ocd) and generalized anxiety disorder (gad) are two main emotional disorders with a chronic course. this research examined the relationship among attentional control and intrusive thoughts (worry, rumination and obsession) in these disorders. it was hypothesized that attentional control is a c...

During electroencephalography (EEG) neurofeedback training, individuals learn to willfully modulate their brain oscillations. Successful modulation has been shown to be related to cognitive benefits and wellbeing. The current paper addresses the specificity of three neurofeedback protocols in influencing first(basic Stroop effect) and second-order (Gratton effect) measures of attentional contro...

Memory is the cognitive ability that allows acquiring, store and recalling information. Anterior thalamic dysfunction creates memory deficits in rats and humans. Anterior thalamus forms a memory network in connection with the hippocampus. This connectivity profile proposes that ventrolateral and anterior thalamus may display a nexus between reminder and control functions, such as action or atte...

This study attempted to replicate findings of an attentional bias towards supraliminal and subliminal smoking cues in the dot-probe task for smokers. Food-related cues were used as a control due to its natural reward properties. Further, the effects of cognitive load during the dot-probe task on attentional bias was explored. Smokers (n=43) and non-smokers (n=41) completed two versions (load an...
