Context-dependent enhancement of declarative memory performance following acute psychosocial stress.
Studies on how acute stress affects learning and memory have yielded inconsistent findings, with some studies reporting enhancing effects while others report impairing effects. Recently, Joëls et al. [Joëls, M., Pu, Z., Wiegert, O., Oitzl, M.S., Krugers, H.J., 2006. Learning under stress: how does it work? Trends in Cognitive Sciences, 10, 152-158] argued that stress will enhance memory only wh...
متن کاملEnhancing effects of acute psychosocial stress on priming of non-declarative memory in healthy young adults.
Social stress affects cognitive processes in general, and memory performance in particular. However, the direction of these effects has not been clearly established, as it depends on several factors. Our aim was to determine the impact of the hypothalamus-pituitary-adrenal (HPA) axis and sympathetic nervous system (SNS) reactivity to psychosocial stress on short-term non-declarative memory and ...
متن کاملStress disrupts context-dependent memory.
Memory is facilitated when the retrieval context resembles the learning context. The brain structures underlying contextual influences on memory are susceptible to stress. Whether stress interferes with context-dependent memory is still unknown. We exposed healthy adults to stress or a control procedure before they learned an object-location task in a room scented with vanilla. Memory was teste...
متن کاملPerformance on a declarative memory task is better in high than low cortisol responders to psychosocial stress.
Increased levels of circulating glucocorticoids (GCs) due to stress have been shown to result in enhanced consolidation and impaired retrieval of memory in humans. Several studies have shown that participants may be categorized as high and low responders with regard to GC levels elicited by stress. In the current study, we studied the differential effects of acute psychosocial stress on declara...
متن کاملStress enhances reconsolidation of declarative memory.
Retrieval of negative emotional memories is often accompanied by the experience of stress. Upon retrieval, a memory trace can temporarily return into a labile state, where it is vulnerable to change. An unresolved question is whether post-retrieval stress may affect the strength of declarative memory in humans by modulating the reconsolidation process. Here, we tested in two experiments whether...
