摘要: AbstractIn this experiment, we developed and evaluated the Portland Arithmetic Stress Task (PAST) as a cognitive stressor to evaluate acute sustained stress reactivity for event-related potential (ERP) studies. The PAST is titrated arithmetic task adapted from Montreal Imaging (MIST), with added experimental control over presentation parameters, improved synchronized acoustic feedback generation of timing markers needed physiological analyzes real-time brain activity. Thirty-one older adults (M = 60 years) completed PAST. EEG was recorded assess feedback-related negativity (FRN) magnitude response through autonomic nervous system activity salivary cortisol. Physiological measures other than included heart rate, respiration rate variability, blood pressure These were collected at several time points throughout task. Feedback-related evoked-potential responses elicited an...
