通道内重复启动的研究提示老年人内隐记忆未受损,这不只体现在视觉通道上还包括其他感觉通道(例如触觉、听觉和嗅觉)。然而很少有研究考察启动任务是否具有通道特异性。在以年轻人为被试的研究中发现跨通道迁移(视觉到触觉和触觉到视觉)和通道内迁移(视觉到视觉,触觉到触觉)具有相似性。一项最近的研究进一步探索老年人在跨通道启动任务上是否受损。结果显示视觉和触觉间的跨通道启动在年轻被试和老年被试上都是保留的且具有对称性。并且,对于自然声响、图片的通道内和跨通道启动任务随着年老化发展仍旧保留。这些行为结果和其它最近神经科学结果显示跨通道启动发生于枕叶后纹状皮层区,而这一区域在老年人中未损坏。这一领域未来的研究方向包括利用不同知觉通道间、利用熟悉的和新异的刺激并结合行为的和脑成像的方法,通过设计完善的跨通道启动来研究正常老人与阿尔兹海默病人,还包括将设计得完善的启动任务包括在用于改善老年人记忆功能的项目中。
Repeated initiation within the channel suggests that the implicit memory in the elderly is not impaired, not only in the visual pathway but also in other sensory pathways (eg, tactile, auditory and olfactory). However, few studies have investigated whether the starting task has channel specificity. In studies with young people as subjects, cross-lane migration (visual to tactile and tactile visual) and intrachannel migration (visual to visual, tactile to tactile) were found to be similar. A recent study further explores whether older people are compromised across cross-launch missions. The results showed that cross-channel activation between visual and tactile was preserved and symmetrical in both young subjects and elderly subjects. And, for natural sounding, in-lane and cross-lane start-up tasks for images still retain with aging. These behavioral findings and other recent neuroscience findings show that cross-channel activation occurs in the posterior occipital lobed cortex, a region that is undamaged in the elderly. Future directions in this area include using normalized and novel stimuli combined with behavioral and brain imaging methods to study normal and Alzheimer’s patients through well-designed cross-channel activations, using different channels of perception, It also includes incorporating well-designed start-up tasks in projects designed to improve memory in the elderly.
