This study examined how calligraphy skill development alters perceived effort and its consequences for aesthetic judgment, from an embodied cognition perspective.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Sixty calligraphy learners (20 novices, 20 intermediates, 20 experts) wrote five standard Chinese characters while pressure sensors and surface electromyography simultaneously recorded pen-tip pressure, upper limb muscle activation, and subjective effort ratings.

This functional recalibration was strongly associated with muscle synergy reorganization (\n                      <jats:italic>r<\/jats:italic>\n                      =\u202f0.74): experts developed a \u201cproximal-dominant, distal-refined\u201d activation pattern, with increased shoulder and arm muscle engagement despite reduced pen-tip pressure. Critically, in predicting aesthetic ratings, perceived effort was a powerful predictor (\n                      <jats:italic>\u03b2<\/jats:italic>\n                      =\u202f0.58,\n                      <jats:italic>p<\/jats:italic>\n                      &amp;lt;\u202f0.001) while actual pressure showed no predictive value (\n                      <jats:italic>\u03b2<\/jats:italic>\n                      =\u202f0.02,\n                      <jats:italic>p<\/jats:italic>\n                      =\u202f0.658). Mediation analysis revealed that perceptual recalibration accounted for 63.2% of skill level\u2019s effect on aesthetic judgment.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>These findings suggest that perception in skilled performance undergoes functional recalibration to optimize task performance, reflecting an adaptive reorganization shaped by embodied experience rather than veridical representation of physical force.
