注意力网络测试（ANT）评估警报和定向线索对测量执行注意力的视觉侧卫任务的影响。先前的研究结果表明，当提供视觉定向线索（提供后续目标的空间和时间信息）时，老年人表现出更大的反应时间（RT）优势。鉴于参与多感觉处理和提示（即警报和定向）的神经基质和网络的重叠，有必要研究多感觉提示对 RT 的影响。目前的研究旨在确定参与者，无论老少，是否能从接收多感官警报和定向线索中受益。包括 18 名年轻人（男性 = 19.17 岁；45% 女性）和 18 名老年人（男性 = 76.44 岁；61% 女性），这些人被确定为非痴呆且没有任何会影响其表现的医疗或精神疾病。结果显示了对执行注意力和定向网络的主要影响，但对警报网络没有影响。在定向方面，老年人和年轻人都对听觉体感（AS）、听觉视觉（AV）和视觉体感（VS）线索表现出显着的定向作用。与单感觉定向效应相比，多感官定向效应的 RT 益处因提示类型和年龄组而异；年轻人对 AS 定向线索表现出更大的 RT 益处，而老年人则对 AV 定向线索表现出更大的 RT 益处。然而，两组都表现出了 RT 对多感官 VS 定向线索的显着益处。这些发现为老年人和年轻人中多感官定向线索而非多感官警报线索的促进作用提供了证据。
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 reaction times (RT) benefits when provided with visual orienting cues that offer both spatial and temporal information of an ensuing target. Given the overlap of neural substrates and networks involved in multisensory processing and cueing (i.e., alerting and orienting), an investigation of multisensory cueing effects on RT was warranted. The current study was designed to determine whether participants, both old and young, benefited from receiving multisensory alerting and orienting cues. Eighteen young (M = 19.17 years; 45% female) and eighteen old (M = 76.44 years; 61% female) 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. RT benefits of multisensory compared to unisensory orienting effects differed by cue type and age group; younger adults demonstrated greater RT benefits for AS orienting cues whereas older adults demonstrated greater RT benefits for AV orienting cues. Both groups, however, demonstrated significant RT benefits for multisensory 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.
