Acute stress, memory, attention and cortisol.
An investigation was conducted to explore the relationship between acute changes in cortisol and memory and attention in the context of an acute naturalistic stressor, namely, examination stress. Sixty students (36 male, 24 female) participated in an assessment of self-reported levels of stress, salivary cortisol, short term memory, selective and divided attention and auditory verbal working me...
متن کاملSex differences in emotional memory consolidation: the effect of stress-induced salivary alpha-amylase and cortisol.
This study examined sex differences in the emotional memory consolidation, and the impact of stress-induced cortisol and salivary alpha amylase responses on emotional memory recall. Following baseline salivary measures, 39 healthy women and 41 men viewed 20 neutral and 20 negative arousing images, and then underwent either a cold pressor stress test or control condition, followed by further sal...
متن کاملStress-induced cortisol hampers memory generalization.
Integrative encoding and generalization across past experiences depends largely on the hippocampus, an area known to be particularly sensitive to stress. Yet, whether stress influences the ability to generalize memories is unknown. We exposed volunteers to a stressor or a control manipulation before they completed an acquired equivalence task probing memory generalization. While stress left lea...
متن کاملAcute consolidation stress enhances reality monitoring in healthy young adults.
Source monitoring refers to cognitive processes involved in making attributions about the origins of memories, knowledge, and beliefs. One particular type of source monitoring with ample practical significance is reality monitoring, i.e., the ability to discriminate between internally vs. externally generated memories. Abundant evidence indicates that exposure to acute stress enhances declarati...
متن کاملFat-induced satiety factor oleoylethanolamide enhances memory consolidation.
The ability to remember contexts associated with aversive and rewarding experiences provides a clear adaptive advantage to animals foraging in the wild. The present experiments investigated whether hormonal signals released during feeding might enhance memory of recently experienced contextual information. Oleoylethanolamide (OEA) is an endogenous lipid mediator that is released when dietary fa...
