Changes in blood glucose and salivary cortisol are not necessary for arousal to enhance memory in young or older adults
Emotional arousal enhances memory, and this memory-enhancing effect may involve neurochemicals released by arousal, such as glucose and cortisol. Physiological consequences of arousal change with age, and these changes may contribute to age-related memory decline. The present study examined whether...

| description | Emotional arousal enhances memory, and this memory-enhancing effect may involve neurochemicals released by arousal, such as glucose and cortisol. Physiological consequences of arousal change with age, and these changes may contribute to age-related memory decline. The present study examined whether emotionally arousing pictures would affect glucose and cortisol levels and enhance memory in young and older adults. Blood glucose and salivary cortisol were measured once before and six times after young and old adults viewed either 60 highly arousing or 60 relatively neutral pictures. Recall for the stimuli was measured 75
min later. The results indicated that recall was impaired in older adults. Arousal as measured by self-report enhanced recall in both young and older adults. However, arousal did not affect glucose or cortisol levels in either group. These findings demonstrate that changes in blood glucose or salivary cortisol levels are not necessary for arousal to enhance memory. |
