People often report word-finding difficulties and other language disturbances when put in a stressful situation. There is, however, scant empirical evidence to support the claim that stress affects speech productivity. To address this issue, we measured speech and language variables during a stressful Trier Social Stress Test (TSST) as well as during a less stressful %26quot;placebo%26quot; TSST (Het et A, 2009). Compared to the non-stressful speech, participants showed higher word productivity during the TSST. By contrast, participants paused more during the stressful TSST, an effect that was especially pronounced in participants who produced a larger cortisol and heart rate response to the stressor. Findings support anecdotal evidence of stress-impaired speech production abilities.
