The 'digit span task', present in one of the few-shot examples, relates to working memory similar to n-back tasks. This dataset features a study named 'EEG, pupillometry, ECG and photoplethysmography, and behavioral data in the digit span task and rest', with a 'Memory' type. Both involve updating and maintaining information, relevant to working memory. This indicates that the n-back task should likely map to the 'Memory' type. The modality will depend on stimulus type, but n-back is often auditory or visual.","metadata_analysis":"The dataset is sparse with information with only placeholder details. Key snippet: 'Tasks: [\"nback\"]' does indicate an N-back task. This suggests a potential working memory/attention paradigm, which typically involves visual or auditory stimuli.","paper_abstract_analysis":"No useful paper information.","evidence_alignment_check":"1. Pathology: Metadata says very little about population ('This is a placeholder dataset.'), suggesting likely 'Healthy'. Pattern would align with typical n-back tasks often not specifying a clinical population. 2. Modality: Metadata does not indicate specific sensory modality, but n-back tasks are frequently either Visual or Auditory. Without further details, inference remains uncertain. 3. Type: Metadata suggests an n-back task, aligning closely with 'Memory', as indicated by the few-shot example with a digit span task.","decision_summary":"Pathology is likely 'Healthy' since metadata provides no evidence of specific clinical conditions, aligning with types of known n-back tasks. Modality is uncertain because of lack of specific stimulus detail, could be 'Visual' or 'Auditory', leading to 'Unknown'. Type is likely 'Memory', supported by n-back task usage in few-shot examples as a cognitive load task. Confidence is lower due to limited information."}},"nemar_citation_count":0,"computed_title":"TX17","nchans_counts":[{"val":64,"count":1}],"sfreq_counts":[{"val":128.0,"count":1}],"stats_computed_at":"2026-05-31T19:34:32.600090+00:00","total_duration_s":1926.1796875,"author_year":"Johnson2023_TX17","canonical_name":null,"bad_channels_info":null,"references_and_links":[""]}}
