The natural learning experience from infancy to emerging adulthood, when considerable cognitive and functional growth is observed, mandates learning multiple real-world skills simultaneously. The present studies investigated whether learning multiple real-world skills simultaneously is possible in older adults and also whether it improves both their cognitive abilities (working memory, episodic memory, and cognitive control) and functional independence.
Over two studies (15 and 27 participants), older adults learned at least three new skills (e.g., Spanish, drawing, music composition) simultaneously for 3 months. Participants completed cognitive and functional assessments before, during, and after the intervention in both studies. Participants were recruited sequentially for an intervention or no-contact control group in Study 1, and Study 2 included only an intervention group, who also completed assessments 4-6 weeks prior to the start of the intervention (i.e., they served as their own control group).
Results from both studies show that simultaneously learning multiple skills is feasible and potentially beneficial for healthy older adults. Learning multiple skills simultaneously increased cognitive abilities in older adults by midpoint of the intervention, to levels similar to performance in a separate sample of middle-aged adults, 30 years younger.
Our findings demonstrate the feasibility and potential of conducting a real-world skill-learning intervention involving learning three novel skills with older adults. Our multiskill intervention may provide broad cognitive gains, akin to the benefits experienced earlier in the life span.
从婴儿期到成年早期的自然学习体验,在此期间观察到大量认知和功能的增长,要求同时学习多种现实世界的技能。本研究旨在探讨老年人是否有可能同时学习多种现实世界的技能,以及这种学习是否能提高他们的认知能力(工作记忆、情景记忆和认知控制)和功能独立性。
在两项研究(15 名和 27 名参与者)中,老年人同时学习至少三种新技能(例如西班牙语、绘画、音乐创作),为期 3 个月。在两项研究中,参与者在干预前后都完成了认知和功能评估。在研究 1 中,参与者按照干预或无接触对照组的顺序被招募,而在研究 2 中,只包括干预组,他们还在干预开始前的 4-6 周完成了评估(即,他们作为自己的对照组)。
两项研究的结果均表明,同时学习多种技能对健康的老年人来说是可行的,并且可能有益。同时学习多种技能可使老年人的认知能力在干预中期提高,达到与年龄相差 30 岁的中年成年人的表现相似的水平。
我们的研究结果表明,与老年人一起进行涉及学习三种新技能的现实世界技能学习干预是可行的和有潜力的。我们的多技能干预可能会带来广泛的认知收益,类似于生命早期经历的益处。
