BACKGROUND
We assessed implicit and explicit emotion in older patients with dementia using biosignals.
METHODS
Fifty patients with dementia and 34 healthy individuals watched 3 videos that aimed to elicit various emotional responses. Electroencephalogram and heart rate variability were recorded.
RESULTS
Patients with dementia experienced less fun and more fear than controls. The high frequency (HF) from the baseline in response to funny stimulation as well as HF from neutral to fear stimulation in the dementia group increased further than in the control group. The slow wave (SW)-fast wave (FW) ratio from neutral to funny stimulation in the control group increased further than in the dementia group. The SW-FW from neutral to fear stimulation was further decreased in the dementia group than in the control group.
CONCLUSIONS
Although patients with dementia were more sensitive to implicit affect, they showed more enhanced imbalance between positive and negative affect in explicit affect assessment.
背景
我们使用生物信号评估了老年痴呆症患者的内隐和外显情绪。
方法
50 名痴呆症患者和 34 名健康个体观看了 3 个旨在引起各种情绪反应的视频。记录了脑电图和心率变异性。
结果
与对照组相比，痴呆症患者体验到的乐趣较少，恐惧较多。在对有趣的刺激的反应中，从基线开始的高频（HF）以及从中性到恐惧刺激的 HF 在痴呆症组中进一步增加，而在对照组中则进一步增加。在对照组中，从中性到有趣的刺激的慢波（SW）-快波（FW）比值进一步增加，而在痴呆症组中则进一步减少。与对照组相比，从中性到恐惧刺激的 SW-FW 进一步降低。
结论
尽管痴呆症患者对内隐情感更敏感，但在明确情感评估中，他们表现出更明显的积极和消极情感之间的不平衡。
