The Attention Network Test (ANT) assesses the effect of alerting and orienting cues on a visual flanker task measuring executive attention. Previous findings revealed that older adults demonstrate greater RT benefits when provided with visual orienting cues that offer both spatial and temporal information of an ensuing target. Given the overlap of neural correlates involved in multisensory processing and cueing (i.e., alerting and orienting), especially in the superior colliculus, thalamus, superior temporal and parietal regions, an investigation of multisensory cueing effects was warranted. The current study was designed to determine whether participants, both old and young, benefited from receiving multisensory alerting and orienting cues on a visual flanker task. Eighteen young (M = 19.17 yrs) and eighteen old (M = 76.44 yrs) individuals that were determined to be non-demented and without any medical or psychiatric conditions that would affect their performance were included. Results revealed main effects for the executive attention and orienting networks, but not for the alerting network. In terms of orienting, both old and young adults demonstrated significant orienting effects for auditory–somatosensory (AS), auditory–visual (AV), and visual–somatosensory (VS) cues. Benefits of multisensory compared to unisensory averaged orienting effects differed by cue type and age group; younger adults demonstrated significantly greater RT benefits for AS orienting cues whereas older adults demonstrated significantly greater RT benefits for AV orienting cues. Both groups, however, demonstrated significant RT benefits for VS orienting cues. These findings provide evidence for the facilitative effect of multisensory orienting cues, and not multisensory alerting cues, in old and young adults.

AbstractThe Attention Network Test (ANT) assesses alerting, orienting, and executive attention. The current study was designed to achieve three main objectives. First, we determined the reliability, effects, and interactions of attention networks in a relatively large cohort of non-demented older adults (n= 184). Second, in the context of this aged cohort, we examined the effect of chronological age on attention networks. Third, the effect of blood pressure on ANT performance was evaluated. Results revealed high-reliability for the ANT as a whole, and for specific cue and flanker types. We found significant main effects for the three attention networks as well as diminished alerting but enhanced orienting effects during conflict resolution trials. Furthermore, increased chronological age and low blood pressure were both associated with significantly worse performance on the executive attention network. These findings are consistent with executive function decline in older adults and the plausible effect of reduced blood flow to the frontal lobes on individual differences in attention demanding tasks.

We investigated the effects of aging on attentional functions using the Attention Network Test (ANT), which enables simultaneous testing of alerting, orienting, and executive networks, and their interactions. Participants were 38 young adults (Mage = 21.35 years) and 36 older adults (Mage = 71.17 years). Although the older adults exhibited a slower overall response, the three attentional functions showed different modulation according to age group and the trial block being completed. Older adults exhibited significant impairment in the alerting function, regardless of whether they were completing the first or second block of trials, whereas their executive function decreased significantly only in Block 2 owing to cognitive fatigue. Both age groups performed similarly for the orienting function. Future researchers should seek to further clarify the specificity of attention function with people aged over 70 years to address their attention disturbance.

Im Rahmen einer multizentrischen, randomisierten, kontrollierten Studie evaluierten wir die klinische Wirksamkeit eines Neurofeedback-Trainings (NF) bei Kindern mit einer Aufmerksamkeitsdefizit-/Hyperaktivitätsstörung (ADHS) und untersuchten die einem erfolgreichen Training zugrunde liegenden neurophysiologischen Wirkmechanismen. Als Vergleichstraining diente ein computergestütztes Aufmerksamkeitstraining, das dem Setting des Neurofeedback-Trainings in den wesentlichen Anforderungen und Rahmenbedingungen angeglichen war. Auf Verhaltensebene (Eltern- und Lehrerbeurteilung) zeigte sich das NF-Training nach Trainingsende dem Kontrolltraining sowohl hinsichtlich der ADHS-Kernsymptomatik als auch in assoziierten Bereichen überlegen. Für das Hauptzielkriterium (Verbesserung im FBB-HKS Gesamtwert) ergab sich eine mittlere Effektstärke (von 0.6). Sechs Monate nach Trainingsende (follow-up) konnte das gleiche Ergebnismuster gefunden werden. Die Ergebnisse legen somit den Schluss nahe, dass NF einen klinisch wirksamen Therapiebaustein zur Behandlung von Kindern mit ADHS darstellt. Auf neurophysiologischer Ebene (EEG; ereignisbezogene Potentiale, EPs) konnten für die beiden Neurofeedback-Protokolle Theta/Beta-Training und Training langsamer kortikaler Potentiale spezifische Effekte aufgezeigt werden. So war für das Theta/Beta-Training beispielsweise die Abnahme der Theta-Aktivität mit einer Reduzierung der ADHS-Symptomatik assoziiert. Für das SCP-Training wurde u. a. im Attention Network Test eine Erhöhung der kontingenten negativen Variation beobachtet, die die mobilisierten Ressourcen bei Vorbereitungsprozessen widerspiegelt. EEG- und EP-basierte Prädiktorvariablen konnten ermittelt werden. Der vorliegende Artikel bietet einen Gesamtüberblick über die in verschiedenen Publikationen unserer Arbeitsgruppe beschriebenen Ergebnisse der Studie und zeigt zukünftige Fragestellungen auf.
