TARAZONA, OLGA; CERON, JEIMMY  and  LAMPREA, MARISOL. Effects of Exposure to an Acute Social Stress Protocol on Systemic Levels of Cortisol and on the Execution of a Sustained and Divided Attention Task. Rev. colomb. psicol. [online]. 2013, vol.22, n.2, pp.347-360. ISSN 0121-5469.

This research project examined the effects of acute social stress induced experimentally with a modified version of TSST (Trier Social Stress Test) on the systemic levels of the cortisol hormone and on the execution of a sustained and divided attention task, in male and female university students. Results showed that the modified TSST protocol caused increases in the systemic levels of cortisol in male participants, but did not affect the execution of the PASAT (Paced Auditory Serial Addition Task). The results are discussed in the light of previous studies in which gender differences in the effects of stress are observed.

Keywords : acute social stress; sustained and divided attention; TSST; PASAT; cortisol.
