Distraction Task

The sensitivity of involuntary attention to top-down modulation was tested using an auditory-visual distraction task and a working memory (WM) load manipulation in subjects performing a simple visual classification task while ignoring contingent auditory stimulation. The sounds were repetitive standard tones (80%) and environmental novel sounds (20%). Distraction caused by the novel sounds was compared across a 1-back WM condition and a no-memory control condition, both involving the comparison of two digits. Event-related brain potentials (ERPs) to the sounds were recorded, and the N1/MMN (mismatch negativity), novelty-P3, and RON components were identified in the novel minus standard difference waveforms. Distraction was reduced in the WM condition, both behaviorally and as indexed by an attenuation of the late phase of the novelty-P3. The transient/change detection mechanism indexed by MMN was not affected by the WM manipulation. Sustained, slow frontal and parietal waveforms related to WM processes were found on the standard ERPs. The present results indicate that distraction caused by irrelevant novel sounds is reduced when a WM component is involved in the task, and that this modulation by WM load takes place at a late stage of the orienting response, all in all confirming that involuntary attention is under the control of top-down mechanisms. Moreover, as these results contradict predictions of the load theory of selective attention and cognitive control, it is suggested that the WM load effects on distraction depend on the nature of the distractor-target relationships.

Selective attention involves top–down modulation of sensory cortical areas, such that responses to relevant information are enhanced whereas responses to irrelevant information are suppressed. Suppression of irrelevant information, unlike enhancement of relevant information, has been shown to be deficient in aging. Although these attentional mechanisms have been well characterized within the visual modality, little is known about these mechanisms when attention is selectively allocated across sensory modalities. The present EEG study addressed this issue by testing younger and older participants in three different tasks: Participants attended to the visual modality and ignored the auditory modality, attended to the auditory modality and ignored the visual modality, or passively perceived information presented through either modality. We found overall modulation of visual and auditory processing during cross-modal selective attention in both age groups. Top–down modulation of visual processing was observed as a trend toward enhancement of visual information in the setting of auditory distraction, but no significant suppression of visual distraction when auditory information was relevant. Top–down modulation of auditory processing, on the other hand, was observed as suppression of auditory distraction when visual stimuli were relevant, but no significant enhancement of auditory information in the setting of visual distraction. In addition, greater visual enhancement was associated with better recognition of relevant visual information, and greater auditory distractor suppression was associated with a better ability to ignore auditory distraction. There were no age differences in these effects, suggesting that when relevant and irrelevant information are presented through different sensory modalities, selective attention remains intact in older age.

Processing Deficits

Abstract BackgroundThe way we perceive our environment is driven by our sensory nervous system and our attentional resources. Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by inattention, impulsivity, and hyperactivity. While cognitive and behavior dysfunctions have broadly been investigated, sensory processing has received less scientific attention. It has been shown, that children with ADHD show processing and modulatory deficits in multiple sensory domains, but very few studies examine to what extent these deficits persist in adult life. We conducted a systematic review of studies investigating sensory processing in adult ADHD.Main BodyUsing the keywords ‘ADHD’ and ‘sensory processing’, Web of Science and MEDLINE database were systematically searched for all articles published up to March 2020. 53 studies were included. Mostly, visual and auditory processing are studied, few investigated multisensory audiovisual and somatosensory processing. In summary, adult ADHD is marked by increased sensory gaining and deficient sensory inhibition. These disturbed gaining and inhibitory mechanisms were most prominent in the auditory modality but also visual modality impairment in terms of stimuli modulation were evident. Electrophysiological studies show alterations across all event-related potential (ERP) components associated with distractibility at early components (bottom-up) and inhibition and stimulus discrimination at later components (top-down). Brain imaging studies on sensory processing in ADHD are scarce, few pointing to higher resting state functional connectivity in visual areas and visual crossmodal activation for auditory stimuli. ConclusionSensory processing deficits extent from childhood to adult ADHD. These deficits are mainly driven by higher distractibility by irrelevant stimuli and modulatory impairment for relevant stimuli. In future studies, the relation of impaired bottom-up and top-down attentional mechanisms should be investigated and how they contribute to sensory processing deficits and clinical symptomatology in adult ADHD. This could help to gather more information about the underling processing deficits, so that specific adjusted training can be provided, that helps to overcome deficits in daily life functioning in e.g., not producing appropriate adaptive responses in social settings.Trial registrationN/A
