Acute stress-induced cortisol elevation during memory consolidation enhances pattern separation
TLDR
Stress induced changes in cortisol differentially affect the consolidation and retrieval stages of memory function, with better discrimination showing a significant correlation with increased cortisol responses.
Post-Encoding Stress Does Not Enhance Memory Consolidation: The Role of Cortisol and Testosterone Reactivity
TLDR
The results suggest a different pattern of relationships between these steroid hormones and the arousal of the negative images, and cortisol reactivity was negatively related to free recall for negative low-arousal pictures, whereas testosterone reactivities was positively related tofree recall fornegative-high arousal and total pictures.
Stress-Induced Increase in Cortisol Negatively Affects the Consolidation of Contextual Elements of Episodic Memories
TLDR
Preliminary evidence that stress-induced cortisol increase negatively affects the consolidation of contextual elements of episodic memories is provided.
Acute Stress Time-dependently Modulates Multiple Memory Systems
TLDR
It is found that postlearning stress, in tandem with increased adrenergic activity during learning, impaired consolidation of context memory and led to preferential expression of SR rather than context memory.
Acute Stress Throughout the Memory Cycle: Diverging Effects on Associative and Item Memory
TLDR
Key differences in how stress shapes the authors' memories for items and associations are revealed, including for high-arousal pairs, preencoding stress enhanced associative memory, whereas postencode stress enhanced item memory.

Associations between Basal Cortisol Levels and Memory Retrieval in Healthy Young Individuals
TLDR
The results support previous findings indicating that higher cortisol levels during retrieval testing hinders recall of episodic memories and extend this view onto interindividual changes in basal cortisol levels.

TLDR
It is indicated that stress can improve familiarity-based recognition, thus showing that stress directly increases the strength of the underlying memories.
Associations between endogenous cortisol levels and emotional memory in young women: Influence of encoding instructions
TLDR
Results indicate that basal cortisol levels, similarly to stress induced cortisol Levels, are associated with emotional memory formation and this effect seems to be modulated by encoding instructions, suggesting a role of focussed attention or arousal induced by testing in this relationship.
Stress administered prior to encoding impairs neutral but enhances emotional long-term episodic memories.
TLDR
It is demonstrated that stress, when administered prior to encoding, produces different patterns of long-term remembering for neutral and emotional episodes, and these differences likely emerge from differential actions of stress hormones on memory-relevant regions of the brain.

TLDR
The hypothesis is proposed that these apparently dual effects of glucocorticoids on memory consolidation and memory retrieval might be related and that the basolateral complex of the amygdala is a key structure in a memory-modulatory system that regulates, in concert with other brain regions, stress and glucOCorticoid effects on both memory consolidationand memory retrieval.
