Here, we examined the neurocomputational processes underlying these biases and examined whether these biases persist across different social contexts. A sample of 154 participants (84% female, mean age = 20.42 years) with subclinical to minimal levels of social anxiety completed a probabilistic selection task in two contexts: performing alone and under social scrutiny. We analyzed frontal midline theta (FM-theta) EEG activity to uncover neurocomputational processes underlying aversive learning in social anxiety. Results showed that participants performed more accurately alone and predominantly preferred a win-stay strategy. Social anxiety led to an increased use of both win-stay and lose-switch strategies (e.g., repeating a choice after receiving positive feedback or switching to a different choice after receiving negative feedback, respectively). In response to negative feedback, FM-theta power predicted post-error slowing, an effect heightened in socially anxious participants. Punishment-based learning was stronger than reward-based learning in all participants, but social anxiety amplified this effect, particularly when participants performed alone. Our findings suggest that social anxiety modulates FM-theta activity in aversive control, promoting reactive avoidance in decision-making. This mechanistic insight links social anxiety to a cascade of orienting, control, and learning biases and positions FM-theta as a potential neural target for interventions aimed at reducing maladaptive avoidance and enhancing adaptive learning in socially anxious individuals.<\/jats:p>","DOI":"10.1162\/jocn.a.2407","type":"journal-article","created":{"date-parts":[[2025,10,30]],"date-time":"2025-10-30T21:02:32Z","timestamp":1761858152000},"page":"826-842","update-policy":"https:\/\/doi.org\/10.1162\/mitpressjournals.corrections.policy","source":"Crossref","is-referenced-by-count":1,"title":["Frontal Midline Theta Promotes Context-dependent Aversive Learning in Social Anxiety"],"prefix":"10.1162","volume":"38","author":[{"given":"Selin","family":"Topel","sequence":"first","affiliation":[{"name":"Leiden University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elise D.","family":"Kortink","sequence":"additional","affiliation":[{"name":"Leiden University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hanjie","family":"Liu","sequence":"additional","affiliation":[{"name":"Leiden University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James F.","family":"Cavanagh","sequence":"additional","affiliation":[{"name":"University of New Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0431-7630","authenticated-orcid":true,"given":"Melle J.
