This dataset similarly centers on visual stimulus categories (faces/illusory faces/non-face objects) and face perception judgments, so by the same convention it maps to Visual + Perception. For Pathology, multiple few-shots show that when no clinical recruitment is stated, labeling defaults to Healthy (e.g., \"EEG: Three armed bandit gambling task\" explicitly says healthy controls; here it is unstated, so we follow the common convention but with lower confidence).","metadata_analysis":"Key stimulus/task facts from the README: (1) \"300 images of human face, illusory face and matched non-face object stimuli.\" (visual images) (2) \"Face-like ratings: participants were asked to rate how easily they could see a face in the image\" (face percept) (3) \"Face/object discrimination: speeded categorisation task\" (perceptual categorization) (4) \"EEG: Stimuli were presented centrally at 3.75 Hz\" (visual presentation) and \"participants performed an orthogonal target detection task\" (attention/oddball-like secondary task, but not the primary construct described in the title/README).

Few-shot pattern SUGGESTS Visual for image-based tasks. ALIGN.\nType: Metadata SAYS \"spontaneous face perception\", \"Face-like ratings\", and \"Face/object discrimination\"—all point to perceptual processing of visual categories.

Evidence: no diagnosis/recruitment details given (supports Unknown), but typical non-clinical perception experiments plus no clinical terms (supports Healthy by convention). Alignment: aligned with few-shot convention; limited direct evidence. Final: Healthy.\n- Modality: (1) Visual (winner) vs (2) Multisensory (runner-up). Evidence for Visual: \"300 images...\", \"Stimuli were presented centrally at 3.75 Hz\". No evidence for additional sensory channels. Final: Visual.\n- Type: (1) Perception (winner) vs (2) Attention (runner-up). Evidence for Perception: \"spontaneous face perception\", \"Face-like ratings... see a face\", \"Face/object discrimination\". Evidence for Attention: \"orthogonal target detection task\" but appears auxiliary. Final: Perception.\nConfidence justification: Modality has 2+ direct quotes strongly supporting Visual; Type has 3 direct quotes supporting perceptual focus; Pathology lacks explicit participant descriptors, so confidence is lower."}},"computed_title":"illusory-face-eeg","nchans_counts":[{"val":68,"count":21}],"sfreq_counts":[{"val":1024.0,"count":21}],"stats_computed_at":"2026-04-22T23:16:00.310729+00:00","total_duration_s":null,"author_year":"Robinson2024_illusory","canonical_name":null}}
