These deficiencies hinder the elucidations of recurrent unauthorised aggression by non-habitual aggressors in high-pressure situations. This research fills this need through case analysis and theoretical synthesis. Using biting occurrences as case studies, it amalgamates the self-control model and reversal theory to develop the stress-depletion-aggression model (SDA). The model outlines a three-stage hostility trajectory: (1) Internal and external stressors systematically diminish self-control resources through physiological and cognitive mechanisms; (2) Continuous depletion undermines inhibitory control and alters motivational priorities; (3) A transition in meta-motivational states (from conformist to negativistic + telic\/mastery + telic) incites unsanctioned aggression. The findings indicate that the SDA model accomplishes multilevel integration of physiological, neurocognitive, and motivational factors; recognises ego depletion as the primary mediator between stress and motivational transitions; and improves predictive capability for unsanctioned aggression beyond conventional theories. The study indicates that unsanctioned aggression arises from the interactive effects of stress accumulation, resource depletion, and significant motivational-state shifts, establishing a scientific foundation for anticipating athlete hostility, formulating remedies, and optimising competition regulations. The proposed SDA model represents a novel theoretical integration, systematically combining the physiological-cognitive mechanisms of self-control resource depletion with the dynamic reversals of meta-motivational states, thereby providing a multi-level, testable framework for understanding and predicting sudden, unsanctioned aggression by non-habitual aggressors under high pressure.<\/jats:p>","DOI":"10.3389\/fpsyg.2025.1670490","type":"journal-article","created":{"date-parts":[[2025,12,5]],"date-time":"2025-12-05T15:29:14Z","timestamp":1764948554000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["From conformity to loss of control: psychological mechanisms in Su\u00e1rez\u2019s biting incidents and the development of the SDA model"],"prefix":"10.3389","volume":"16","author":[{"given":"Zhao","family":"Zhang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shaoran","family":"Yu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2025,12,4]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"27","DOI":"10.1146\/annurev.psych.53.100901.135231","article-title":"Human aggression","volume":"53","author":"Anderson","year":"2002","journal-title":"Annu.
