用脑电波预测4-6岁儿童共情力,更客观精准。
BEAM: Brainwave Empathy Assessment Model for Early Childhood
- 基于多视角脑电信号,捕捉共情的认知与情绪动态
- 在CBCP数据集上超越现有方法,准确率显著提升
- 适合发展心理学、儿童神经科学及早期干预研究者
幼儿共情对其社交与情感发展至关重要,但传统方法仅依赖自评或观察评分,易受偏见影响且无法客观捕捉共情形成过程。脑电图(EEG)提供了客观替代方案,但现有方法多提取静态特征,忽视时间动态。为此,我们提出新型深度学习框架——脑波共情评估模型(BEAM),用于预测4-6岁儿童的共情水平。BEAM利用多视角EEG信号,同时捕获共情的认知与情绪维度。框架包含三个核心组件:1)基于LaBraM的编码器实现高效时空特征提取;2)特征融合模块整合多视角互补信息;3)对比学习模块增强类别分离。在CBCP数据集上验证表明,BEAM在多个指标上均优于现有最先进方法,展现出客观评估共情的潜力,并为儿童亲社会发展的早期干预提供初步洞见。
原文摘要 · Abstract (English)
Empathy in young children is crucial for their social and emotional development, yet predicting it remains challenging. Traditional methods often only rely on self-reports or observer-based labeling, which are susceptible to bias and fail to objectively capture the process of empathy formation. EEG offers an objective alternative; however, current approaches primarily extract static patterns, neglecting temporal dynamics. To overcome these limitations, we propose a novel deep learning framework, the Brainwave Empathy Assessment Model (BEAM), to predict empathy levels in children aged 4-6 years. BEAM leverages multi-view EEG signals to capture both cognitive and emotional dimensions of empathy. The framework comprises three key components: 1) a LaBraM-based encoder for effective spatio-temporal feature extraction, 2) a feature fusion module to integrate complementary information from multi-view signals, and 3) a contrastive learning module to enhance class separation. Validated on the CBCP dataset, BEAM outperforms state-of-the-art methods across multiple metrics, demonstrating its potential for objective empathy assessment and providing a preliminary insight into early interventions in children's prosocial development.
