Cross-modal transfer (CMT) occurs when a person (or animal) learns to perform a task in response to cues in one sensory modality (e.g., audition) and then learns an essentially similar task in response to cues of a different modality (e.g., vision). The rate of learning the second task is faster than it would be without having had the prior training experience. Dr. Delay is studying the effects of post-injury, cross-modal transfer of learning on recovery of behavioral function following brain damage. His early studies have already shown, for example, that prior training to an auditory stimulus aids in the recovery of ability to detect a change in light intensity following damage to the visual areas of the cerebral cortex. This research is helping us understand the more general conditions (e.g., cue characteristics) necessary for CMT to enhance behavioral recovery after brain injury. These experiments also provide insights into brain-behavior relationships which, ultimately, will contribute to the foundation of clinical rehabilitation programs.

跨模态迁移（CMT）发生在人（或动物） 学习根据一种感觉的提示来执行任务， 模态（例如，试听），然后学习一个本质上类似的 任务响应于不同模态的提示（例如，视觉）。 学习第二个任务的速度比它应该的要快 而没有之前的培训经验。 迪莱博士正在研究受伤后， 学习转移对行为功能恢复的影响 脑损伤 例如，他的早期研究已经表明， 预先接受听觉刺激的训练有助于恢复 检测损伤后光强度变化的能力 大脑皮层的视觉区域。 这项研究帮助我们了解更普遍的 条件（例如，提示特征）， 促进脑损伤后的行为恢复。 这些 实验还提供了对大脑行为的深入了解， 这些关系最终将有助于 临床康复计划的基础。
