New Factorized Inverse Decision Model Analyzes Verbalized Cognitive Tasks

Researchers have developed a Factorized Inverse Decision Model (FIDM) that analyzes verbalized cognitive tasks by decomposing task-execution likelihood into action and effort factors. This model uses a language model to generate structured task-execution traces from raw verbal transcripts, enabling factorized inference. When applied to data from 400 older adults performing a grocery-shopping dialog task for cognitive screening, FIDM demonstrated the ability to selectively estimate intended factors and preserve distinctions even when aggregate behavioral summaries were matched. The model also showed gains in cognitive-status classification by providing information complementary to existing clinical scores and trajectory summaries. AI

IMPACT This research could lead to more nuanced cognitive assessments by analyzing verbal data, potentially improving diagnostic tools for conditions affecting decision-making.
