This guides the convention that when a task is explicitly visual, Modality should be Visual. However, the current dataset’s paradigm is a “Color Change Detection Task”, which by common experimental convention is often used to probe visual working memory/attentional capacity rather than pure sensory perception; thus the few-shot mainly anchors the Modality mapping, while Type requires additional inference beyond the provided few-shots.","metadata_analysis":"Key available metadata is sparse. Explicit snippets:\n1) Title: \"Color Change Detection Task\" (suggests a visual color-based change detection paradigm).\n2) Tasks: \"CCDT\" (an acronym consistent with Color Change Detection Task).\n3) Participants: \"Subjects: 24\" (no stated diagnosis, age, or recruitment criteria; no mention of patients/controls).","paper_abstract_analysis":"No useful paper information.","evidence_alignment_check":"Pathology:\n- Metadata says: only \"Subjects: 24\" with no clinical descriptors.\n- Few-shot pattern suggests: many cognitive EEG tasks are in healthy volunteers, but this is not a metadata FACT.\n- Alignment: INSUFFICIENT metadata; cannot confirm Healthy. Choose Unknown.\n\nModality:\n- Metadata says: \"Color Change Detection Task\" (color change implies visual stimuli).\n- Few-shot pattern suggests: visual tasks (e.g., visual discrimination) -> Modality=Visual.\n- Alignment: ALIGNS (both point to Visual).\n\nType:\n- Metadata says: only the task name \"Color Change Detection Task\" / \"CCDT\" without further description.\n- Few-shot pattern suggests: visual discrimination tasks often labeled Perception; however change-detection paradigms are commonly used for visual working memory/attention, which is not directly exemplified in the few-shots.\n- Alignment: PARTIAL/UNCERTAIN; task is visual, but cognitive construct (Perception vs Memory vs Attention) is not explicitly stated.
