In the present study, we aimed to investigate how acute stress exerts its heterogeneous effects. Based on biophysical network models, we hypothesized that acute stress would improve occipital-mediated ultra-short-term and to a lesser degree affect occipital- and frontal-mediated short-term and working, and impairs hippocampal-mediated long-term memory processes and their respective behavioral measures. To test this, 111 healthy individuals (57 female) underwent both the Trier Social Stress Test (TSST) and a control test. Immediately afterward, participants' performance was measured in four memory tasks (Rapid Serial Visual Presentation, RSVP, Match-to-Sample, MTS, N-Back, NB and Free-Recall, FR tasks). TSST exposure seems to impair long-term memory (AC
