Substantial evidence from animal studies suggests that enhanced memory associated with emotional arousal results from an activation of beta-adrenergic stress hormone systems during and after an emotional experience. To examine this implication in human subjects, we investigated the effect of the beta-adrenergic receptor antagonist propranolol hydrochloride on long-term memory for an emotionally arousing short story, or a closely matched but more emotionally neutral story. We report here that… Expand
Cortisol has different effects on human memory for emotional and neutral stimuli
In all memory tests, subjects who viewed the emotional story scored better for the emotionally arousing story parts, indicating that arousal enhances memory, and confirms a non-linear interaction between cortisol and arousal on memory formation. Expand
β-Adrenergic blockade during reactivation reduces the subjective feeling of remembering associated with emotional episodic memories
Results show that propranolol before reactivation abolished the superior memory for emotional relative to neutral stimuli and decreased 'remember' judgments for emotional items, suggesting that β-adrenergic blockade during reactivation made emotional memories comparable to neutral memories. Expand
Memory for emotional events: differential effects of centrally versus peripherally acting β-blocking agents
The results support the view that memory of a mild emotional event involves activation of central, but not necessarily peripheral β-adrenergic receptors, while propranolol impaired memory in subjects who saw the emotional version of the slide show. Expand
The effect of beta-adrenergic blockade after encoding on memory of an emotional event
This experiment does not support a role for noradrenaline in the post-encoding phase and on the later processes of consolidation and retrieval, and it remains possible that with a different dosage or timing protocol a post-treatment effect of noradRenaline in humans can be found. Expand
Enhanced memory for emotional material following stress-level cortisol treatment in humans
It is suggested that high cortisol levels during arousing events result in enhanced memory in humans, and previous work on corticosteroid enhancement of memory is extended. Expand
Exposure To A Significant Stressor Simultaneously Enhances Memory For Emotional Aspects Of An Event And Disrupts Memory For Non-Emotional Aspects Of The Same Event
The present experiment demonstrates that exposure to a significant stressor simultaneously enhances memory for emotional aspects of an event and disrupts memory for non-emotional aspects of the sameExpand
Emotional Memory Mechanisms in the Human Brain
Neurobiological accounts of emotional memo ry have been derived largely from animal models investi gating the encoding and retention of memories for events that signal threat. This literature hasExpand
Emotional context modulates subsequent memory effect
It is demonstrated that successful episodic encoding is differentially modulated by emotional context, which contributes to the understanding of the interaction of emotion and cognition and is of general relevance for studies of episodic memory. Expand
The impact of stress on neutral and emotional aspects of episodic memory
The present experiment demonstrates that exposure to a significant psychological stressor (administered before watching a slide show) preserves or even enhances memory for emotional aspects of anExpand
Emotion-induced retrograde amnesia and trait anxiety.
The results presented here indicated a significant interaction of the TA with EME and ERA and the dependency of these biases on the consciously controlled use of memory. Expand
