The Muddy Waters of Modeling Empathy in Language: The Practical Impacts of Theoretical Constructs

2025-01-24

AI Summary

This study addresses the theoretical foundations and empirical efficacy of empathy modeling in NLP: Why do current models exhibit unstable performance on empathy tasks? We systematically analyze divergent psychological definitions of empathy—direct, abstract, and proximal—and propose the first dimension-aligned, multi-dimensional operationalization framework, coupled with a theory-driven task taxonomy. Using cross-task transfer learning and performance attribution analysis, we empirically demonstrate—for the first time—that theoretical alignment (rather than data scale or model architecture) predominantly determines transfer success; tasks directly predicting specific empathy components yield optimal transfer performance. Our findings reveal that the dimensionality, measurability, and data compatibility of empathy definitions constitute critical bottlenecks for model performance. The work establishes a unified evaluation standard and a theory-method co-design pathway for interpretable, reproducible computational empathy modeling.

Abstract

Conceptual operationalizations of empathy in NLP are varied, with some having specific behaviors and properties, while others are more abstract. How these variations relate to one another and capture properties of empathy observable in text remains unclear. To provide insight into this, we analyze the transfer performance of empathy models adapted to empathy tasks with different theoretical groundings. We study (1) the dimensionality of empathy definitions, (2) the correspondence between the defined dimensions and measured/observed properties, and (3) the conduciveness of the data to represent them, finding they have a significant impact to performance compared to other transfer setting features. Characterizing the theoretical grounding of empathy tasks as direct, abstract, or adjacent further indicates that tasks that directly predict specified empathy components have higher transferability. Our work provides empirical evidence for the need for precise and multidimensional empathy operationalizations.
