For stimulus Modality, few-shots map stimulus channel (not response) to labels: visual tasks (e.g., “visual discrimination task… moving dots”) are labeled Visual, even when responses are motor (mouse click). For Type, few-shots show that simple sensory discrimination maps to Perception, while tasks outside the provided cognitive-type taxonomy can map to Other (no explicit language label exists in Allowed Labels). A comparable convention is the Visual discrimination example labeled Perception, but picture naming likely emphasizes language production beyond pure perception, pushing toward Type=Other rather than Perception.","metadata_analysis":"Available metadata is very sparse.
