Working memory task demands were manipulated by varying the cognitive load (1-back/3-back) and time limit (standard-paced/time-restricted), and stress was measured both subjectively via self-report and objectively via heart rate and heart rate variability (HRV). Eighty undergraduate participants completed a series of questionnaires and the n-back task while wearing a heart rate monitor. Accuracy was best in the 1-back blocks; however, ACE group differences in n-back accuracy were not detected. This study suggests that those with high ACEs had an elevated experience of subjective stress throughout the task and may have been able to adapt to this stress as reflected by greater HRV and the maintenance of similar n-back accuracy as compared to those with low ACEs.","abstract_html":"This study aimed to explore the relationships among adverse childhood experiences (ACEs), working memory as assessed by an n-back task, and stress.
