From keystrokes to scores: Toward a multidimensional predictive model of writing evaluation by humans and large language models across linguistic, cognitive, and social dimensions
Qiao Gan, Benjamin Adams
Analyzed 4245 essays with keystroke and demographic data to compare human and LLM scoring across linguistic, cognitive, and social dimensions. Found moderate agreement but different patterns of association, indicating that human and LLM assessments rely on partially distinct cues.
Original abstract
Automated writing evaluation (AWE) has traditionally emphasized textual features such as vocabulary and syntax, while often overlooking writers’ social identities and cognitive behaviors – factors central to understanding writing as a multidimensional construct. With the increasing integration of large language models (LLMs) into AWE, questions remain about how their assessments align with human judgments and the sources of potential divergences. This study investigates how linguistic (e.g., lexical diversity), cognitive (e.g., pausing behavior), and social (e.g., gender) factors covary with essay scores assigned by human raters and LLMs. We analyzed 4245 argumentative essays paired with demographic metadata and keystroke-logging data, using correlation analyses, random forest models, and regression-based approaches to examine relationships among writer characteristics, writing-process features, textual features, and essay scores. Results showed moderate agreement between human and LLM scores, but the two scoring systems exhibited different patterns of association with linguistic, cognitive, and social variables. These findings suggest that human and LLM evaluations rely on partially different cues and demonstrate how socio-cognitive metadata can be used to examine the factors associated with writing assessment decisions. By moving beyond text-only comparisons, this approach provides a complementary lens for understanding why and how human and machine judgments converge or diverge.
