The aging population is growing rapidly. Proposing interventions that enhance the cognitive functions or strategies that delay the onset of disabilities associated with age is a topic of capital interest for the biopsychosocial health of our species. In this work, we employed musical improvisation as a focal environmental activity to explore its ability to improve memory in older adults. We present two studies: the first one evaluated neutral memory using the Rey Complex Figure (RCF) and the second one evaluated emotional memory using International Affective Picture System (IAPS). A group of 132 volunteers, between the ages of 60 and 90, participated in this investigation. Fifty-one of them were musicians with more than 5 years of formal musical training. After acquisition of neutral (Study 1) or emotional (Study 2) information, the groups of older adults were exposed to music improvisation (experimental intervention) or music imitation (control intervention) for 3 min. We then evaluated memory through two tasks (free recall and recognition), by means of immediate and deferred measures (after a week). We found a significant improvement in memory among participants involved in music improvisation, who remembered more items of the RCF and images from IAPS than the imitation group, both in the immediate and deferred evaluation. On the other hand, participants who had musical knowledge had a better performance in neutral visual memory than non-musicians. Our results suggest that a focal musical activity can be a useful intervention in older adults to promote an enhancement in memory.
老年人口正在迅速增长。提出增强认知功能的干预措施或延缓与年龄相关的残疾发作的策略,是关乎我们人类生物心理社会健康的一个至关重要的话题。在这项研究中,我们将音乐即兴创作作为一项重点环境活动,以探究其改善老年人记忆力的能力。我们展示了两项研究:第一项研究使用雷氏复杂图形(RCF)评估中性记忆,第二项研究使用国际情感图片系统(IAPS)评估情绪记忆。132名年龄在60岁至90岁之间的志愿者参与了这项调查。其中51人是接受过5年以上正规音乐训练的音乐家。在获取中性(研究1)或情绪(研究2)信息后,老年人群体被暴露于音乐即兴创作(实验干预)或音乐模仿(对照干预)中3分钟。然后,我们通过两项任务(自由回忆和识别),借助即时和延迟测量(一周后)来评估记忆力。我们发现,参与音乐即兴创作的参与者的记忆力有显著改善,在即时和延迟评估中,他们比模仿组记住了更多的雷氏复杂图形项目和国际情感图片系统中的图像。另一方面,有音乐知识的参与者在中性视觉记忆方面比非音乐家表现更好。我们的研究结果表明,一项重点音乐活动可能是促进老年人记忆力增强的一种有用干预措施。
