These examples show that oddball paradigms are typically labeled by (i) stimulus channel (auditory/visual/multisensory) and (ii) the study aim (sensory processing vs cognitive control vs clinical focus). Another relevant few-shot by stimulus goal is \"Subcortical responses to music and speech...\" (Auditory, Perception), which—like the current dataset—targets auditory stimulus encoding/processing rather than learning or motor behavior. This convention supports labeling the current harmonic-sound oddball as Auditory modality and Perception type, unless metadata explicitly frames it as a cognitive control/clinical study (it does not).","metadata_analysis":"Key stated facts from the dataset README include: (1) population description: \"twenty adult participants\" (no diagnosis/condition mentioned). (2) stimulus/task: \"harmonic complex sound (HCS) stimuli\" and \"in an auditory oddball protocol\". (3) stated research focus via the cited paper title: \"Pre-attentive Pitch Processing of Harmonic Complex Sounds\". Together these indicate an auditory stimulation oddball paradigm intended to probe pitch processing (sensory/perceptual processing), with no explicit clinical recruitment.","paper_abstract_analysis":"No useful paper information beyond the cited article title and citation (no abstract text provided in the metadata).","evidence_alignment_check":"Pathology: Metadata says \"twenty adult participants\" with no disorder mentioned; few-shot pattern suggests Healthy when no clinical recruitment is stated; ALIGN (no conflict), but pathology remains an inference (absence of evidence).\nModality: Metadata says \"harmonic complex sound (HCS) stimuli\" and \"auditory oddball protocol\"; few-shot oddball examples map modality directly to stimulus channel (auditory vs visual vs multisensory); ALIGN.\nType: Metadata emphasizes \"Pre-attentive Pitch Processing\" (sensory pitch processing) and uses an oddball protocol; few-shot convention indicates that when the goal is sensory encoding/processing (e.g., auditory stimulus-response characterization), Type maps to Perception rather than Motor/Learning; ALIGN. A potential alternative is Attention because oddball can index attentional orienting/MMN, but the metadata framing is primarily perceptual (pitch processing).","decision_summary":"Pathology top-2: (1) Healthy — supported by lack of any clinical recruitment statement and the generic \"twenty adult participants\" wording; (2) Unknown — plausible because 'healthy' is not explicitly stated. Winner: Healthy (no evidence of clinical cohort). Confidence limited because this is an inference.\nModality top-2: (1) Auditory — supported by \"harmonic complex sound (HCS) stimuli\" and \"auditory oddball protocol\"; (2) Multisensory — unlikely since no visual/tactile stimuli are described. Winner: Auditory with strong direct textual support.\nType top-2: (1) Perception — supported by \"Pre-attentive Pitch Processing\" and the use of frequency-varying harmonic sounds; (2) Attention — plausible because oddball paradigms are often used for attentional deviance processing, but the stated target construct is pitch processing. Winner: Perception.\nConfidence notes: Modality and Type have explicit task/stimulus and construct phrasing; Pathology lacks an explicit 'healthy' statement."}},"computed_title":"SINGSING","nchans_counts":[{"val":339,"count":38}],"sfreq_counts":[{"val":250.0,"count":38}],"stats_computed_at":"2026-04-22T23:16:00.311835+00:00","total_duration_s":null,"canonical_name":null,"name_confidence":0.96,"name_meta":{"suggested_at":"2026-04-14T10:18:35.343Z","model":"openai/gpt-5.2 + openai/gpt-5.4-mini + deterministic_fallback"},"name_source":"canonical","author_year":"Chanoine2025"}}
