A variety of cognitive deficits can lead to difficulties performing complex behavioural sequences and thus, disability in the performance of routine and rehabilitation behaviours. Interventions to date involve increasing support or providing behavioural training. Assistive technologies for cognition have the potential to augment cognitive capacity thus enabling the performance of behavioural sequences. Guide is an assistive technology for cognition that scaffolds task performance by providing verbal prompts and responding to verbal feedback. Guide was used to provide verbal support and guidance for eight amputees (mean age 64), with cognitive impairment of vascular origin, putting on their prosthetic limbs. Participants were referred to the research due to problems learning the correct behavioural sequence. The research used repeated trials with random assignment to intervention and baseline conditions. The voice-mediated assistive technology for cognition resulted in a significant reduction of safety critical errors and omitted steps. Discussion focuses upon the relation between voice-mediated cognitive support for memory and executive function, and suggestions are made for future research.
各种认知缺陷可导致执行复杂行为序列的困难，从而导致日常行为和康复行为的障碍。迄今为止的干预措施包括增加支持或提供行为训练。认知辅助技术有可能增强认知能力，从而能够执行行为序列。Guide 是一种认知辅助技术，它通过提供口头提示和响应口头反馈来支撑任务表现。Guide 用于为 8 名因血管源性认知障碍而安装假肢的截肢者（平均年龄 64 岁）提供口头支持和指导。由于学习正确的行为序列存在问题，参与者被转介到研究中。研究使用重复试验，随机分配到干预和基线条件。语音介导的认知辅助技术导致安全关键错误和遗漏步骤的显著减少。讨论集中在语音介导的认知记忆和执行功能支持之间的关系，并为未来的研究提出了建议。
