Abstract

Interoception is the detection of signals that arise from within the body. Interoceptive sensitivity has been found to be associated with affect and cognition among younger adults, and examination of these relationships in older adult samples is beginning to emerge. Here, we take an exploratory approach to determine how demographic, affective, and cognitive variables relate to interoceptive sensitivity in neurologically normal older adults, aged 60-91 years old. Ninety-one participants completed a comprehensive neuropsychological battery, self-report questionnaires, and a heartbeat counting task to measure interoceptive sensitivity. Our findings revealed several relationships: 1) interoceptive sensitivity was inversely correlated with measures of positive emotionality: participants with higher interoceptive sensitivity tended to have lower levels of positive affect and trait extraversion; 2) interoceptive sensitivity was found to positively correlate with cognition: participants who performed better on the heartbeat-counting task also tended to perform better on a measure of delayed verbal memory; and 3) when examining the predictors of interoceptive sensitivity in a single hierarchical regression model, higher interoceptive sensitivity was related to: higher time estimation, lower positive affect, lower extraversion, and higher verbal memory. In total, the model accounted for 38% of the variability in interoceptive sensitivity (R2 = .38). These results suggest that, among older adults, interoceptive sensitivity is facilitative for aspects of cognition but perhaps disruptive for certain aspects of emotional experience.

老年人的互感、情感和认知。
内感知是对来自身体内部信号的检测。在年轻人中,人们发现内感知灵敏度与情感和认知有关,而在老年人样本中对这些关系的研究也开始出现。在此,我们采用一种探索性的方法来确定人口统计学、情感和认知变量与神经正常的 60-91 岁老年人的内感知灵敏度之间的关系。91 名参与者完成了全面的神经心理测试、自我报告问卷和心跳计数任务,以测量感知间灵敏度。我们的研究结果显示了几种关系:1)感受间灵敏度与积极情绪测量呈反向关系:感受间灵敏度较高的参与者往往具有较低水平的积极情绪和特质外向性;2)感受间灵敏度与认知呈正向关系:在心跳计数任务中表现较好的参与者往往在延迟言语记忆测量中也表现较好;以及 3)在一个单一的分层回归模型中研究感受间灵敏度的预测因素时,较高的感受间灵敏度与以下因素有关:较高的时间估计、较低的积极情绪、较低的外向性和较高的言语记忆。该模型总共解释了 38% 的感知间灵敏度变化(R2 = 0.38)。这些结果表明,在老年人中,感知间灵敏度对认知的某些方面有促进作用,但对情感体验的某些方面可能具有破坏作用。

期刊介绍: Experimental Aging Research is a life span developmental and aging journal dealing with research on the aging process from a psychological and psychobiological perspective. It meets the need for a scholarly journal with refereed scientific papers dealing with age differences and age changes at any point in the adult life span. Areas of major focus include experimental psychology, neuropsychology, psychobiology, work research, ergonomics, and behavioral medicine. Original research, book reviews, monographs, and papers covering special topics are published.
