(2) the \"EEG: Probabilistic Learning...\" dataset, labeled Type=Learning, which guides labeling when the core design involves an intervention/training phase with pre/post measurement intended to change performance.

Few-shot patterns suggest pure discrimination maps to Perception (as in the visual discrimination example), but explicit intervention structure supports Learning (as in the probabilistic learning example). This is a mild TENSION but not a direct conflict; the intervention/pre-post framing is stronger for the dataset-level purpose, so Learning is selected.","decision_summary":"Top-2 Pathology candidates: (1) Healthy — supported by absence of any clinical terms/diagnoses and the general experimental grouping only (\"intervention group\" vs \"control group\"); (2) Unknown — possible because participants are not explicitly described as healthy. Winner: Healthy. \nTop-2 Modality candidates: (1) Visual — supported by \"letters \\\"b\\\" and \\\"d\\\"\" and \"visual search task\" and stimulus-coded events for letters; (2) Multisensory/Other — unlikely since no non-visual stimuli are mentioned. Winner: Visual. \nTop-2 Type candidates: (1) Learning — supported by the explicit three-stage pre/post with an \"intervention measurement\" and intervention vs control groups (\"Stage 1 (before measurement)...\"; \"Stage 2 (intervention measurement)...\"; \"Stage 3 (after measurement)...\"; \"assigned to two groups\"); (2) Perception — supported by the 2AFC letter discrimination component (\"two-alternative forced choice discrimination task\").
