STRESSING MEMORY 1 Running head: EMOTIONAL AND NEUTRAL MEMORY UNDER STRESS 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

چکیده
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 same event. These results are consistent with theories invoking differential effects of stress on brain systems responsible for encoding and retrieving emotional memories (the amygdala) and non-emotional memories (the hippocampal formation), and inconsistent with the view that memories formed under traumatic levels of stress are qualitatively the same as those formed under ordinary circumstances (e.g., McNally, 2003; Shobe & Kihlstrom, 1997). These data, which are also consistent with results obtained in a number of studies using animals and humans, have implications for the legal system, clinical practice, and theories regarding human memory.

Autobiographical Brand Images Give a Higher Chance to False Memory as Compared to Neutral Images
Consumers’ prior experiences shape an episodic memory which largely influences their decision-making process. This episodic memory is mainly linked to cognitive and emotional perception and we know that a brand image influences our cognitive and emotional perception. Nevertheless, it has not been well described how autobiographical memories of brand images differ from those of other types of im...
متن کاملEvent-related nociceptive arousal enhances memory consolidation for neutral scenes.
The superior memory for emotional events has been attributed to the beneficial effects of noradrenaline released into the amygdala attributable to arousal. Noradrenaline mediates the effects of different hormones and neurotransmitters, including adrenal stress hormones on consolidation (McGaugh, 2004; Roozendaal et al., 2009). The majority of human fMRI studies of the enhancement of emotional m...
متن کاملTrue or false? Memory is differentially affected by stress-induced cortisol elevations and sympathetic activity at consolidation and retrieval.
Adrenal stress hormones released in response to acute stress may yield memory-enhancing effects when released post-learning and impairing effects at memory retrieval, especially for emotional memory material. However, so far these differential effects of stress hormones on the various memory phases for neutral and emotional memory material have not been demonstrated within one experiment. This ...
متن کاملImmediate recall influences the effects of pre-encoding stress on emotional episodic long-term memory consolidation in healthy young men.
The stress-associated activation of the hypothalamus-pituitary-adrenal axis influences memory. Several studies have supported the notion that post-learning stress enhances memory consolidation, while pre-retrieval stress impairs retrieval. Findings regarding the effects of pre-encoding stress, in contrast, have been rather inconsistent. In the current two studies, the impact of an immediate ret...
متن کاملStress impairs the reconsolidation of autobiographical memories.
Stress enhances memory consolidation, in particular for emotional material. When reactivated, consolidated memories return to a fragile state again and thus require another period of stabilization, called reconsolidation. Rodent studies suggest that memory reconsolidation is impaired by stress. Here we examined in healthy humans the effect of stress on the reconsolidation of autobiographical me...
