Factors such as psychological well-being, sleep quality, and athletic coping skills can influence athletic performance. Mindfulness-based interventions, including mindfulnessbased stress reduction (MBSR), have been shown to benefit these factors, suggesting they may, at least indirectly, benefit athletic performance. Moreover, while mindfulness training has been linked to better accuracy in some high-precision sports, whether it can improve non-precision elements of athletic performance is unclear. The objective of this study was to investigate the influence of MBSR on psychological well-being, sleep, athletic coping skills, and rowing performance in collegiate rowers in a controlled experimental design. Members of a Division I NCAA Women's Rowing team completed either an 8-week MBSR course along with their regular athletic training program (Intervention group) or the athletic training program alone (Control group). Measurements of interest were taken at baseline and again either during or shortly following the intervention. In contrast to the Control group, the Intervention group showed improvements in psychological well-being, subjective and objective sleep quality, athletic coping skills, and rowing performance as measured by a 6,000-m ergometer test. Improvements in athletic coping skills, psychological well-being, and subjective sleep quality were all correlated with increases in mindfulness in the Intervention group. These results suggest that mindfulness training may benefit non-precision aspects of athletic performance. Incorporating mindfulness training into athletic training programs may benefit quality of life and performance in student athletes.

Age-related memory decline has been proposed to result partially from impairments in memory consolidation over sleep. However, such decline may reflect a shift toward selective processing of positive information with age rather than impaired sleep-related mechanisms. In the current study, young and older adults viewed negative and neutral pictures or positive and neutral pictures and underwent a recognition test after sleep or wake. Subjective emotional reactivity and affect were also measured. Compared to waking, sleep preserved valence ratings and memory for positive but not negative pictures in older adults and negative but not positive pictures in young adults. In older adults, memory for positive pictures was associated with slow wave sleep. Furthermore, slow wave sleep predicted positive affect in older adults but was inversely related to positive affect in young adults. These relationships were strongest for older adults with high memory for positive pictures and young adults with high memory for negative pictures. Collectively, these results indicate preserved but selective sleep-dependent memory processing with healthy aging that may be biased to enhance emotional well-being.

We describe the outcome 2 years later of elderly Cambridge residents who had been diagnosed as demented using the Cambridge Mental Disorders of the Elderly Examination. Mortality rates were high but diagnoses were confirmed for all of the 43 moderate and severe cases who survived for this period, and for 51 of the 56 subjects who had been rated initially as mildly demented; 28 of the 56 mildly demented subjects progressed to more severe levels of impairment. As many as 12 of the 24 original minimally demented cases showed evidence of intellectual deterioration, which lends weight to the validity of this experimental category.

Sleep benefits memory in young adults, and this effect may be particularly strong for representations associated with negative emotion. Many aspects of sleep important for memory consolidation change with aging, particularly by middle age, suggesting that sleep-related consolidation may be reduced. However, the influence of sleep on memory has rarely been investigated in a middle-aged population. In the current study, young and middle-aged adults viewed negative and neutral pictures and underwent a recognition test after sleep or wake. Subjective emotional reactivity was also measured. Compared to waking, sleep benefited memory in young adults. Performance did not differ between sleep and wake groups in middle-aged adults, and it matched the level of young adults who slept. The effect of sleep versus wake was not influenced by memory valence in either age group. These results suggest the relative influence of sleep compared to wake on memory declines with aging, specifically by middle age, and that this decline extends to negative memory.
