The stimuli were designed and administered using E-Prime\nsoftware (Version 2) at Arkansas Children Nutrition Center (ACNC), Little Rock, Arkansas.\nThe University of Arkansas for Medical Sciences (UAMS) approved the study protocol. This research\nwas supported by USDA/Agricultural Research Service Project 6026-51000-012-06S.\n Raw data files\nThe data was acquired with a Geodesic Net Amps 300 system running Netstation 4.5.2 software using\nthe 128-channel Geodesic Hydrocell Sensor Net™ (Magstim EGI., Eugene OR, USA).\nNo operations have been performed on the data.\nParticipant data\nThe *Participants.tsv* file contains age, gender, body mass index (BMI), and performance.\nHow to cite\nAll use of this dataset in a publication context requires the following paper\nto be cited:\nAlatorre-Cruz, G.C., Downs, H., Hagood, D., Sorensen, S.T.,  Williams, D.K., Larson-Prior, L.

The Braille example shows that when the paper/README defines a special population focus, Pathology uses that focus even if participants.tsv says “control” (convention: use the recruited/targeted condition). The Digit span example shows that a cognitively demanding task can map to a specific cognitive Type when the construct is explicit (there: working memory), otherwise less-specific cognitive tasks may fall back to Type=Other. There is no direct few-shot example for obesity + arithmetic, so we rely mainly on metadata facts for Pathology and on general convention for Modality/Type.","metadata_analysis":"Key metadata facts:\n1) Population: \"electrophysiological signal from sixty-two obese and non-obese preteens\" and \"The *Participants.tsv* file contains age, gender, body mass index (BMI), and performance.\" This indicates recruitment stratified by obesity/BMI in preteens.\n2) Task: \"during a delayed-verification math task\" and the cited paper title: \"Effect of obesity on arithmetic processing in preteens with high and low math skills.\" This indicates an arithmetic/verification cognitive paradigm.\n3) Stimulus delivery tool: \"The stimuli were designed and administered using E-Prime software\" (stimulus modality not explicitly stated, but E-Prime tasks are typically screen-based unless otherwise noted).","paper_abstract_analysis":"No useful paper information (no abstract provided in the input).","evidence_alignment_check":"Pathology:\n- Metadata says: \"sixty-two obese and non-obese preteens\" and participants file includes \"body mass index (BMI)\".\n- Few-shot pattern suggests: when a condition defines groups, use that condition label (e.g., Parkinson’s, TBI, dementia examples).\n- ALIGN: both indicate obesity-status is a recruitment factor → Pathology=Obese.\n\nModality:\n- Metadata says: \"stimuli... administered using E-Prime\" but does not explicitly state visual/auditory/tactile.\n- Few-shot pattern suggests: task-based cognitive experiments using stimulus presentation software and not described as auditory/tactile are commonly Visual.\n- PARTIAL ALIGN / weak evidence: inferred Visual due to typical E-Prime math presentation; not explicitly stated.\n\nType:\n- Metadata says: \"delayed-verification math task\" and paper title emphasizes \"arithmetic processing\".\n- Few-shot pattern suggests: map Type to the primary cognitive construct when it is clearly one of the allowed categories (e.g., digit span → Memory; gambling/RL → Learning/Affect/Decision-making). Here, \"arithmetic processing\" does not cleanly map onto the available Type labels.\n- ALIGN for choosing a fallback: use Type=Other when the construct is cognitive but not covered by the label set.","decision_summary":"Top-2 candidate selections:\n\n1) Pathology\n- Candidate A: Obese\n  Evidence: \"sixty-two obese and non-obese preteens\"; participants include \"body mass index (BMI)\"; paper title: \"Effect of obesity on arithmetic processing...\".\n- Candidate B: Development\n  Evidence: \"preteens\" indicates a developmental-age cohort.\nHead-to-head: Obese is the explicit recruited group factor and central stated focus (obesity effect) → select Obese. (Age alone does not imply Development pathology per allowed-label definition.)\n\n2) Modality\n- Candidate A: Visual\n  Evidence: \"stimuli... administered using E-Prime\" + math/arithmetic tasks are typically visually presented; no mention of auditory stimulation.\n- Candidate B: Unknown\n  Evidence: modality is not explicitly stated (no \"visual\"/\"auditory\" keywords).\nHead-to-head: Visual is plausible but inferred; because there is no direct statement, Visual wins narrowly over Unknown.\n\n3) Type\n- Candidate A: Other\n  Evidence: task described as \"delayed-verification math task\"; paper focus \"arithmetic processing\" (not directly one of Perception/Attention/Memory/Learning/Decision-making/Motor/Resting/Sleep).\n- Candidate B: Memory\n  Evidence: \"delayed-verification\" can involve short-term maintenance/working memory, but this is not explicitly stated as the primary construct.\nHead-to-head: The explicit aim is arithmetic processing rather than a named memory construct → select Other.\n\nConfidence justification:\n- Pathology high: multiple explicit obesity-focused phrases (README + paper title + BMI field).\n- Modality moderate-low: inferred from E-Prime/math task; no explicit modality statement.\n- Type moderate: explicit task/paper focus supports a cognitive-task label, but mapping to a specific allowed cognitive construct is ambiguous."}},"nemar_citation_count":1,"computed_title":"Effect of obesity on arithmetic processing in preteens with high and low math skills.
