A secondary analogy is the DPX cognitive control dataset (TBI / Visual / Attention), which shows that some task paradigms can be labeled Attention when the goal is cognitive control; however, n-back is more commonly used as a working-memory load manipulation, so Memory is the stronger convention match.","metadata_analysis":"Very limited metadata suggests this is a placeholder with a single task label only. Key snippets: (1) README: \"TX17 dataset\\nThis is a placeholder dataset.\" (no population/stimulus details). (2) Tasks: \"nback\" (only paradigm hint). (3) Participants overview: \"Subjects: 1\" (no diagnosis/control/age/health information).","paper_abstract_analysis":"No useful paper information.","evidence_alignment_check":"Pathology: Metadata says nothing about recruitment/diagnosis (\"This is a placeholder dataset.\"; \"Subjects: 1\"). Few-shot patterns cannot infer pathology from task alone. ALIGNMENT: not applicable (no metadata fact); choose Unknown.\nModality: Metadata provides no stimulus channel (only \"nback\"). Few-shot conventions show modality is based on stimulus type (e.g., digit span explicitly \"presented auditorily\"), but no such fact exists here. ALIGNMENT: not applicable; choose Unknown.\nType: Metadata indicates the paradigm \"nback\". Few-shot convention maps working-memory paradigms (digit span) to Type=Memory, suggesting n-back should also map to Memory. No conflicting metadata. ALIGNMENT: aligns (task implies working memory).","decision_summary":"Pathology top-2: (1) Unknown—supported by lack of any diagnosis/health statement (\"This is a placeholder dataset.\"; \"Subjects: 1\"); (2) Healthy—possible but unsupported. Final: Unknown. Confidence 0.4 because no explicit recruitment facts.\nModality top-2: (1) Unknown—no stimulus description beyond \"nback\"; (2) Visual—common for n-back but not stated. Final: Unknown. Confidence 0.4 due to missing stimulus facts.\nType top-2: (1) Memory—n-back is a standard working-memory task (task listed as \"nback\"; few-shot digit span labeled Memory); (2) Attention—alternate interpretation if framed as cognitive control, but no such framing is provided. Final: Memory. Confidence 0.6 because it is contextual inference from task name only, without detailed metadata about study aims."}},"nemar_citation_count":0,"computed_title":"TX17","nchans_counts":[{"val":64,"count":1}],"sfreq_counts":[{"val":128.0,"count":1}],"stats_computed_at":"2026-04-22T23:16:00.308582+00:00","total_duration_s":1926.1796875,"author_year":"Johnson2023_TX17","canonical_name":null}}
