“…Participants reporting attention problems performed significantly worse in the LVF than participants not reporting attention problems, suggesting an RH attention deficit (Figure 4). These results are consistent with Poynter et al's study [14], which showed that nondisabled subjects who self-reported relatively high levels of attention problems on the Conner's ADHD scale performed significantly worse on two behavioral measures of attention when stimuli were presented in the LVF versus RVF. This result was most prominent in the condition with spatial cues, indicating that deficits in orienting attention to the LVF (using RH mechanisms) tend to correlate with self-rated attention problems.…”

“…This RH orienting deficit has also been found in studies of subjects with attention deficit disorder and also nondisabled subjects who self-report high levels of attention problems in everyday activities [14]. Several studies have provided evidence that patients with attention deficit/ hyperactivity disorder (ADHD) exhibit worse attentional deficits for visual information presented in the LVF versus right visual field (RVF), indicating a RH deficit [15][16][17].…”

“…Several studies have provided evidence that patients with attention deficit/ hyperactivity disorder (ADHD) exhibit worse attentional deficits for visual information presented in the LVF versus right visual field (RVF), indicating a RH deficit [15][16][17]. Furthermore, a recent study found that non-ADHD individuals who self-report relatively high levels of attentional problems in everyday activities also exhibit an RH deficit in attentional tasks [14]. So, we were interested in comparing the performance of mTBI subjects in our sample who complained of attention problems with the performance of those that did not.…”

Abstract-Mild traumatic brain injury (mTBI) and posttraumatic stress disorder (PTSD) are prevalent dual impairments in veterans returning from the wars in Iraq and Afghanistan. Attention problems are a common self-reported complaint of veterans with mTBI, but relatively few studies have investigated the types and levels of behavioral attentional deficits present in veterans with mTBI and PTSD. The purpose of this study was to compare visual attentional performance between samples of veterans with both mTBI and PTSD (mTBI+PTSD), PTSD only, and a control group. Overall, the attentional responses of the mTBI+PTSD group were slower than those of the PTSD and control groups. The response times were also more variable, suggesting difficulty with attentional vigilance. Additionally, we found evidence of hemispheric asymmetries in attentional performance. Participants with mTBI+PTSD were less efficient in orienting visual attention to stimuli flashed to the left visual field (LVF), suggesting a right hemisphere deficit. Overall, we found that veterans who had sustained an mTBI and had a coexisting PTSD diagnosis displayed longer response times and were less accurate than the PTSD and control groups, especially when cues were presented to the LVF.

“…Indeed, [42] showed that many dyslexic individuals have attentional impairments in the subclinical range, which may not always be detected in small samples. Furthermore, asymmetric performance depending on position are not only reported for individuals with dyslexia but also for individuals with high ADHD scores [43], thus suggesting that general attention capabilities might be related to the position effects in cueing paradigms.…”

Visuo-spatial cueing in children with differential reading and spelling profiles

et al. 2017

Dyslexia has been claimed to be causally related to deficits in visuo-spatial attention. In particular, inefficient shifting of visual attention during spatial cueing paradigms is assumed to be associated with problems in graphemic parsing during sublexical reading. The current study investigated visuo-spatial attention performance in an exogenous cueing paradigm in a large sample (N = 191) of third and fourth graders with different reading and spelling profiles (controls, isolated reading deficit, isolated spelling deficit, combined deficit in reading and spelling). Once individual variability in reaction times was taken into account by means of z-transformation, a cueing deficit (i.e. no significant difference between valid and invalid trials) was found for children with combined deficits in reading and spelling. However, poor readers without spelling problems showed a cueing effect comparable to controls, but exhibited a particularly strong right-over-left advantage (position effect). Isolated poor spellers showed a significant cueing effect, but no position effect. While we replicated earlier findings of a reduced cueing effect among poor nonword readers (indicating deficits in sublexical processing), we also found a reduced cueing effect among children with particularly poor orthographic spelling (indicating deficits in lexical processing). Thus, earlier claims of a specific association with nonword reading could not be confirmed. Controlling for ADHD-symptoms reported in a parental questionnaire did not impact on the statistical analysis, indicating that cueing deficits are not caused by more general attentional limitations. Between 31 and 48% of participants in the three reading and/or spelling deficit groups as well as 32% of the control group showed reduced spatial cueing. These findings indicate a significant, but moderate association between certain aspects of visuo-spatial attention and subcomponents of written language processing, the causal status of which is yet unclear.

“…Although important for investigating the influences of activation and/or of a lack of activation of the attentional networks on behavioral responses and coping cognitive strategies, unfortunately behavioral studies101112131415 cannot tell much about the timing, localization and activation dynamics of brain underpinnings of the conflict resolution mechanisms and about the kind of influences of valid spatial orienting on its resolution.…”

How voluntary orienting of attention and alerting modulate costs of conflict processing

There is evidence that pre-cued valid orienting of attention to competing information diminishes costs of brain processing of conflict. Still unclear, because scantily addressed by neuroimaging studies and mostly analyzed by means of behavioral indexing, it is whether conflict undergoes an equivalent modulation by tonic and pre-cued phasic alerting. Here, we investigated the functional relationships between attention orienting, alerting and executive systems using the Attention Network Test (ANT). Both reaction times (RTs) and ERPs were recorded. In line with previous literature, results showed that both RTs and a so-called ERPs conflict negativity (CN), prominent at anterior scalp and indexing conflict processing, were positively modulated by a prior valid orienting of attention onto the location of conflicting stimuli. Indeed, in this condition both kinds of markers showed faster latencies, while CN also reached higher amplitude values than in both alerting conditions, and, in turn, in pre-cued phasic alerting than in uncued tonic alerting. Moreover, while CN was larger over the right hemisphere independent of functional conditions, it was strongly modulated by the latter over the left hemisphere. Our ERP findings support the views of conflict modulation by both orienting and phasic alerting and of a functional integration between attentional brain networks.
