Abstract:

Multimodal data enables accurate cognitive structure diagnosis as well as comprehensive feedback on various cognitive characteristics (e.g., cognitive style). This work presents three multimodal cognitive diagnosis models based on joint-cross-loading modeling to achieve joint analysis of response accuracy, response time (RT), and visual fixation counts (FC). The results of the empirical and simulation studies show that: (1) joint analysis is more suitable for multimodal data than separated analysis; (2) the proposed models can directly use the information in RT and FC to improve the estimation accuracy of latent ability and latent attributes; (3) the proposed models' parameters can be well recovered; and (4) negative results caused by ignoring cross-loading are more serious than those caused by redundant consideration.

Key words: cognitive diagnosis, multimodal data, item response times, fixation counts, cognitive style, eye-tracking
