Pilot data from a study conducted by the author’s laboratory in which male college students underwent the Trier Social Stress Test (Kirschbaum et al., 1993) or a control procedure, and subsequently completed the Operation Span, a measure of working memory. Men in the Trier group scored higher on the Operation Span compared with men in the control group, t(58) = 3.56, p = 0.001. All participants provided informed consent, and the study was approved by the Notre Dame Institutional Review Board. Note that these findings should be considered preliminary, as data collection is ongoing.
