The temporal memory is formed from encoding and consolidation processes of duration in memory. These memory processes can be enhanced in an emotional situation in which there is an increase in the arousal level, typical of the alert phase of the General Adaptation Syndrome (SAG) of stress. However, prolonged emotional experiences, such as in the stress situations, can cause damage to the memory. The present study aims to examine whether the relationship between arousal and temporal memory remains by the perceived stress level among nurses. The methodology used will be the Sociodemographic Questionnaire, Working and Health conditions, the Perceived Stress Scale - PSS, Job Stress Scale - JSS and the Childhood Trauma Questionnaire (CTQ), to select nurses with and without stress. After the application of these instruments, participants will perform the Temporal Generalization experiment. They will memorize a standard duration (learning phase) in a condition that increases the arousal level (aversive condition) and in a non aversive condition (control), then, after 24 hours, they will perform a recall test. In the recall test, participants will judge whether the comparison durations are similar or different from the standard duration, previous learned. Before and after the learning and the test phase of time experiment, saliva samples will be collected for the measurement of salivary cortisol nurses to verify the effect of arousal. Data will be analyzed using descriptive statistics and ANOVA. (AU)
