The present study investigated the impact of bilingualism on efficiency of alerting, orienting and executive attention by means of the Lateralized Attention Network Test (LANT). Young adult bilinguals who had been exposed to their second language before the age of four years showed a reduced conflict cost and a larger alerting effect in terms of response time (RT), while no difference between bilinguals and monolinguals was observed in overall RT. Bilinguals also outperformed monolinguals on accuracy in both conflict and non-conflict trials, though the effect in the latter condition was very small. Moreover, while a left visual field advantage for accuracy of conflict resolution was present in the monolingual group, bilinguals did not show the asymmetry. The findings suggest that bilingualism enhances the efficiency of executive network while reducing its lateralization. The larger alerting effect in bilinguals is hypothesized to be related to bilinguals’ more efficient executive control, which may support processes of response anticipation or temporal orienting.

Performance decrements after sleep loss have been extensively studied and are usually attributed to generic attentional deficits. This claim, however, is based on the view of attention as a unitary construct, despite evidence that it should be considered a multidimensional cognitive ability. The aim of the present study was to evaluate the impact of one night of sleep deprivation on the efficiency of three attentional networks, defined by Posner and Raichle (1994) in anatomical and functional terms, as alerting, orienting, and executive control. Thirty participants performed the Attention Network Test at 9:00 a.m. following two different sleep conditions: baseline (a normal night of sleep) and deprivation (24 hrs of wakefulness). Results showed an overall slowing in reaction times and a significant decrease in accuracy after sleep deprivation. Sleep deprivation selectively affected the three attentional networks, given that only executive control efficacy significantly decreased after sleep deprivation. By contrast, phasic alerting and orienting showed no differences in the two sleep conditions. Thus, performance deficits following sleep deprivation do not reflect global attentional deficits.

The present study explored the effects of three different activity conditions on three attentional functions: alerting, orienting, and executive control. A group of highly experienced cyclists performed the Attention Network Test–Interactions (Callejas, Lupiáñez, & Tudela, 2004) at rest, during moderate aerobic exercise, and during intense aerobic exercise. Results indicated that aerobic exercise accelerated reaction time and reduced the alerting effect compared with the rest condition. However, aerobic exercise did not modulate the functioning of either the orienting or the executive control attentional networks. No differences in reaction time or attentional functioning were observed between the two aerobic exercise workloads. The present results suggest that moderate aerobic exercise modulates the functioning of phasic alertness by increasing the general state of tonic vigilance.

Purpose The purpose of this study was to evaluate whether previously reported questionnaire-based differences in self-regulatory behaviors (Eggers, De Nil, & Van den Bergh, 2009, 2010) between children who stutter (CWS) and children who do not stutter (CWNS) would also be reflected in their underlying attentional networks. Method Participants consisted of 41 CWS (mean age = 6;09; years;months) and 41 CWNS (mean age = 6;09) ranging in age from 4;00 to 9;00. Participants were matched on age and gender. The efficiency of the attentional networks was assessed by using the computerized Attention Network Test (Fan, McCandliss, Sommer, Raz, & Posner, 2002). Results Primary results indicated that CWS had a significantly lower efficiency of the orienting network compared with CWNS, whereas no differences were found on the alerting or executive control network. Conclusion Current findings corroborate previously found differences in self-regulatory behavior and were taken to suggest a possible role for attentional processes in developmental stuttering.

The attentional system is comprised of three networks: alerting, orienting, and executive control, all of which are associated with unique neural systems. Research examining motivationcognition interactions implicate the dopaminergic and locus-coeruleus norepinephrine systems in attentional and motivational processes, both of which show age differences. The current study was conducted to explore the mechanisms through which gain and loss motivation affect attention across the lifespan, using behavioural and electrophysiological markers of attentional networks. Younger adults (18-33 years) and older adults (65-80 years) completed an incentivized version of the Attention Network Test. Our behavioural results showed age differences in incentive sensitivity, such that responses were modulated as a function of incentives. We also examined cue-N1, target-N1, and target-P3, which showed transient incentive-based modulation, and depended on incentive valence. Overall, our study provides evidence for age-related differences in the modulation of attentional networks, and contributes new insights into the mechanisms behind motivation-cognition interactions.

Intellectually gifted children (IGC) have high performance in many domains of the attention than intellectually average children (IAC). However, few studies investigated the development of the alerting, orienting and executive control networks, in IGC. The aim of our study is to analyze the development of these networks in IGC compared to typical developing children and young adults.Fifty-four IGC (age range 8–14 years-old) were compared to 54 IAC (age range 8–14 years-old) and 60 young adults (age range 19–25 years-old) using the Attention Network Test (ANT) to assess these three attentional constructs. Results indicated IGC had better performance than IAC in executive control only. Both children groups have lower attentional network scores than young adults. IGC have probably the same development of the IAC in all attentional networks to the late childhood at adolescence. But they have better ability to focus volitionally in order to solve a simple conflict than IAC.

In recent years, three attentional networks have been defined in anatomical and functional terms. These functions involve alerting, orienting, and executive attention. Reaction time measures can be used to quantify the processing efficiency within each of these three networks. The Attention Network Test (ANT) is designed to evaluate alerting, orienting, and executive attention within a single 30-min testing session that can be easily performed by children, patients, and monkeys. A study with 40 normal adult subjects indicates that the ANT produces reliable single subject estimates of alerting, orienting, and executive function, and further suggests that the efficiencies of these three networks are uncorrelated. There are, however, some interactions in which alerting and orienting can modulate the degree of interference from flankers. This procedure may prove to be convenient and useful in evaluating attentional abnormalities associated with cases of brain injury, stroke, schizophrenia, and attention-deficit disorder. The ANT may also serve as an activation task for neuroimaging studies and as a phenotype for the study of the influence of genes on attentional networks.

Would it be helpful to inform a driver about when a conflicting traffic situation is going to occur? We tested whether temporal orienting of attention could enhance executive control to select among conflicting stimuli and responses. Temporal orienting was induced by presenting explicit cues predicting the most probable interval for target onset, which could be short (400 ms) or long (1,300 ms). Executive control was measured both by flanker and Simon tasks involving conflict between incompatible responses and by the spatial Stroop task involving conflict between perceptual stimulus features. The results showed that temporal orienting facilitated the resolution of perceptual conflict by reducing the spatial Stroop effect, whereas it interfered with the resolution of response conflict by increasing flanker and Simon effects. Such opposite effects suggest that temporal orienting of attention modulates executive control through dissociable mechanisms, depending on whether the competition between conflicting representations is located at perceptual or response levels.
