Task Completion Times and Complexity Metric Values from a Controlled Molecular Integration Study

Experimental data from a controlled study in which 23 participants completed 10 molecular integration tasks (labeled A–J). The dataset includes task completion times in seconds for all participants and tasks, and computed structural complexity metric values (spectral and density-based) for the 8 tasks included in the mixed-effects regression analysis (Tasks A, B, D, E, F, G, I, J). Tasks C and H are excluded from the metrics file because retrospective metric calculation was not possible for those tasks.
