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\nRaw data files\n\nThe data were 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.\n\nParticipant data\n\nThe *Participants.tsv* file contains age, gender, body mass index (BMI), and weight status (WS)\n\nHow to cite\n\nAll use of this dataset in a publication context requires the following paper to be cited: Alatorre-Cruz GC, Downs H, Hagood D, Sorensen ST, Williams DK, Larson-Prior L.
