“…An audiovisual WM task version with irrelevant stimuli from the auditory modality interleaved between relevant visual stimuli or vice versa also did not reveal an age-related cross-modal suppression deficit (Guerreiro et al, submitted for publication). In general, evidence from these studies agrees with prior cross-modal research in aging, which consistently demonstrates preserved multisensory performance in aging in the face of unisensory cognitive decline, notably in the visual domain (Hugenschmidt et al, 2009a, 2009b; Laurienti et al, 2006). This body of work suggests that older adults may benefit most when functioning within multisensory than unisensory environments.…”

All of us are familiar with the negative impact of interference on achieving our task goals. We are referring to interference by information, which either impinges on our senses from an external environmental source or is internally generated by our thoughts. Informed by more than a decade of research on the cognitive and neural processing of interference, we have developed a framework for understanding how interference impacts our neural systems and especially how it is regulated and suppressed during efficient on-task performance. Importantly, externally and internally generated interferences have distinct neural signatures, and further, distinct neural processing emerges depending on whether individuals must ignore and suppress the interference, as for distractions, or engage with them in a secondary task, as during multitasking. Here, we elaborate on this cognitive framework and how it changes throughout the human lifespan, focusing mostly on research evidence from younger adults and comparing these findings to data from older adults, children, and cognitively impaired populations. With insights gleaned from our growing understanding, we then describe three novel translational efforts in our lab directed at improving distinct aspects of interference resolution using cognitive training. Critically, these training approaches were specifically developed to target improved interference resolution based on neuroplasticity principles and have shown much success in randomized controlled first version evaluations in healthy aging. Our results show not only on-task training improvements but also robust generalization of benefit to other cognitive control abilities. This research showcases how an in-depth understanding of neural mechanisms can then inform the development of effective deficit-targeted interventions, which can in turn benefit both healthy and cognitively impaired populations.

“…As a result of selective attention to the visual modality, visual stimulus processing may have been enhanced relative to auditory stimulus processing (e.g., McDonald et al, 2005;Spence & Parise, 2010). It has been shown that selectively attending to only one sense also modulates multisensory integration of sensory information of that and another sensory modality (e.g., Hugenschmidt, Mozolic, & Laurienti, 2009;Mozolic, Hugenschmidt, Peiffer, & Laurienti, 2008;Talsma, Doty, & Woldorff, 2007). In some cases, modality-specific attention even reduced multisensory response enhancement to statistical facilitation (see Mozolic et al, 2008, Fig.…”

“…For instance, older adults exhibit baseline increases in multisensory integration during modality-specific attention (Hugenschmidt et al, 2009), and, increased distraction from ambient sensory information within the experimental environment (Stevens et al, 2008). During passive viewing of repeating objects superimposed over novel scenic images, Chee et al (2006) found that visual cortical adaptation to objects was preserved in young adults but impaired in older adults.…”

We examined visual selective attention under perceptual load-simultaneous presentation of task-relevant and -irrelevant information-in healthy young and older adult human participants to determine whether age differences are observable at early stages of selection in the visual cortices. Participants viewed 50/50 superimposed face/place images and judged whether the faces were male or female, rendering places perceptible but task-irrelevant. Each stimulus was repeated, allowing us to index dynamic stimulus-driven competition from places. Consistent with intact early selection in young adults, we observed no adaptation to unattended places in parahippocampal place area (PPA) and significant adaptation to attended faces in fusiform face area (FFA). Older adults, however, exhibited both PPA adaptation to places and weak FFA adaptation to faces. We also probed participants' associative recognition for face-place pairs post-task. Older adults with better place recognition memory scores were found to exhibit both the largest magnitudes of PPA adaptation and the smallest magnitudes of FFA adaptation on the attention task. In a control study, we removed the competing perceptual information to decrease perceptual load. These data revealed that the initial age-related impairments in selective attention were not due to a general decline in visual cortical selectivity; both young and older adults exhibited robust FFA adaptation and neither group exhibited PPA adaptation to repeated faces. Accordingly, distracting information does not merely interfere with attended input in older adults, but is co-encoded along with the contents of attended input, to the extent that this information can subsequently be recovered from recognition memory.
