    "concept_summary": "A subject rests a finger on a calibrated rest equipped with two pressure transducers (vertical and horizontal). At random auditory cues the subject briefly presses the finger, attempting to express a pre-selected fantasy emotion (e.g., anger, love, joy). The pressure waveforms are recorded, averaged across many trials, and characteristic dynamic shapes (\"sentic forms\") are identified for each emotion. Correlation analysis shows high intra-subject stability and cross-cultural similarity, suggesting universal brain-programmed movement patterns.",
