Although DPX is a different paradigm than Flanker, both are classic cognitive control/conflict-monitoring tasks used to elicit ERPs linked to attention/executive control (e.g., ERN). This example guides mapping a cognitive-control ERP task to Type=Attention rather than Perception or Motor. For Modality, multiple few-shot examples show that tasks involving on-screen targets/cues (e.g., motor/imagery targets; visual discrimination) are labeled Visual, which is the conventional mapping for Flanker tasks as typically implemented with visual arrow/letter stimuli.","metadata_analysis":"Key metadata facts:\n- Title explicitly identifies the paradigm: \"PURSUE LRP/ERN Flanker\".\n- README states: \"Flanker Experiment from the PURSUE project\" and points to ERP CORE task design: \"The task design can be found in the publication by Kappenman et al.(2021).

Confidence supported by 2+ explicit non-clinical recruitment cues.\n\nModality candidates:\n1) Visual — Evidence: paradigm is \"Flanker\" (commonly visual arrow/letter arrays) and title references ERP components (LRP/ERN) typically elicited in visual flanker tasks.\n2) Unknown — Metadata does not explicitly say \"visual\"/\"auditory\" stimuli.\nWinner: Visual (best fit given standard Flanker stimulus delivery; no evidence for auditory/tactile). Confidence limited because stimulus modality is not explicitly stated.\n\nType candidates:\n1) Attention — Evidence: \"Flanker\" is a cognitive control/conflict task; title includes \"ERN\" (error monitoring) and \"LRP\" (response preparation), aligning with attention/executive control; few-shot DPX cognitive control labeled Attention supports this mapping.\n2) Decision-making — Could be argued because it involves choosing responses, but primary construct in Flanker ERP work is typically conflict/attention control rather than value-based decision policy.\nWinner: Attention (stronger construct match to Flanker/ERN conventions).
