A University of Virginia study was conducted to determine if stress enhance or impair memory Consolidation.

Overall results provide consistent evidence that stress does not uniformly enhance memory consolidation. Although prior research has shown that stress during recall can interfere with memory, the current experiments obtained evidence of interference when stress was introduced after learning and participants had returned to baseline levels of arousal before recall. This is the first evidence of which the authors are aware that stress can actually impair consolidation of declarative memories. We tested several hypotheses for these effects, including those concerned with stimulus type, rehearsal, gender, hormonal influences (from menstrual cycle and oral contraceptive use), and opportunity for post-encoding processing. Nevertheless, we continued to obtain the same robust finding that stress-induced arousal impairs long term memory.

In each experiment, exposure to a stressor interfered with, rather than enhanced, long term memory for associated material.

Another was conducted to determine if chronic stress induces a hyporeactivity of the autonomic nervous system in response to acute mental stressor and impairs cognitive performance in business executives.

The study is the first to demonstrate a blunted reactivity of the ANS when male subjects with chronic psychological stress were subjected to an acute mental stressor, and this change could contribute to impairments in cognitive performance.


Another study also demonstrated that it is better not to deal with two tasks at the same time when stressed since acute psychosocial stress reduces task shielding in dual-task performance.

Following successful stress induction, as indicated by increases in salivary α-amylase (sAA) and cortisol that reflect increases in sympathetic nervous system and hypothalamus-pituitary-adrenal (HPA) axis activity, respectively, stressed individuals displayed reduced task shielding relative to controls. This result was further substantiated by a correlation between treatment-related increase in cortisol, but not sAA, and between-task interference, suggesting a potential role of the HPA stress response for the development of the observed effects. As an additional finding, when the volunteers were categorized with regard to their action-state orientation, their orientation did not interact with stress but did reveal generally increased between-task interference, and thus inferior task shielding, for state-oriented as compared to action-oriented individuals.

Connie’s comments: Chronic stress, experiencing stressors over a prolonged period of time, can result in a long-term drain on the body.
