{"pk":49658,"title":"How Altruistic Motivation Synchronizes Brain-Muscle Coherence to Enhance Motor Performance","subtitle":null,"abstract":"While extrinsic and intrinsic motivation have been well studied, the effects of altruistic motivation on motor performance remain largely unexplored. This study investigates the influence of altruistic motivation on brain–muscle coherence and its effect on improving time to task failure. Thirty-one participants performed two high-intensity isometric grip tasks to failure. The first trial was conducted without any extra motivational incentive, while the second trial was performed under one of three conditions: altruistic, extrinsic, or control. Electroencephalogram (EEG) and electromyogram (EMG) signals were recorded during both trials. Our results demonstrate that only the altruistic group improved their performance from the first to the second trial (68%; p = 0.004). The altruistic group exhibited increased EEG–EMG coherence in the alpha and beta bands and reduced delta coherence. These findings suggest that prosocial motivation restructures neural oscillatory activity, optimizing force control and endurance.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Cognitive Neuroscience; Emotion; Empathy; Motor control; Sensory Processing; cognitive neuropsychology; Electroencephalography (EEG)"}],"section":"Papers with Poster Presentation","is_remote":true,"remote_url":"https://escholarship.org/uc/item/2z80c4vn","frozenauthors":[{"first_name":"Tatiana Okubo Rocha","middle_name":"","last_name":"Pinho","name_suffix":"","institution":"California State University San Marcos","department":""},{"first_name":"Pedro Augusto","middle_name":"","last_name":"Pereira","name_suffix":"","institution":"Anhembi Morumbi","department":""},{"first_name":"Osmar","middle_name":"","last_name":"Pinto Neto","name_suffix":"","institution":"California State University San Marcos","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2025-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/49658/galley/37620/download/"}]}
