There has been a proliferation of cognitive training studies investigating the efficacy of various cognitive training paradigms as well as strategies for improving cognitive control in the elderly. While some have found support for the transfer of training, the majority of training studies show modest to no transfer effects. When transfer effects have been(More)
BACKGROUND AND PURPOSE T2 hypointensity in the basal ganglia of patients with MS has been associated with clinical progression and cognitive decline. Our objectives were the following: 1) to compare signal in T2WI, R2 (ie, 1/T2), and R2* (ie, 1/T2*) relaxation rates and quantitative susceptibility mapping; and 2) to investigate the associations among MR(More)
BACKGROUND Cognitive reappraisal is a form of emotion regulation that alters emotional responding by changing the meaning of emotional stimuli. Reappraisal engages regions of the prefrontal cortex that support multiple functions, including visceral control functions implicated in regulating the immune system. Immune activity plays a role in the preclinical(More)
Dispositional mindfulness is associated with lower levels of perceived stress, with increased emotional regulation and cognitive control proposed as mechanisms underlying these stress-buffering effects of mindfulness. Within aging, these controlled processes represent paradoxically divergent trajectories such that older adults exhibit reduced cognitive(More)
OBJECTIVE Dispositional mindfulness exhibits a positive association with quality of life (QoL). One potential mechanism for this association is enhanced emotion regulation abilities. Individuals with multiple sclerosis (MS) experience a range of physical, cognitive, and affective impairments, thus reducing overall QoL. The current cross-sectional study(More)
OBJECTIVES Research shows that dispositional mindfulness is associated with metrics of overall well-being, with enhanced emotion regulation potentially underlying these salutary effects. However, the role of regulation strategy use remains poorly understood. In this study, we examined age-variant associations between dispositional mindfulness, emotion(More)
Increasing age is characterized by greater positive affective states. However, there is mixed evidence on the implementation of emotion regulation strategies across the life span. To clarify the discrepancies in the literature, we examined the modulating influence of contextual factors in understanding emotion regulation strategy use in older and young(More)
OBJECTIVE In clinical trials, omega-3 fatty acid supplementation improves symptoms in psychiatric disorders involving dysregulated mood and impulse control, yet it is unclear whether in healthy adults, omega-3 fatty acid supplementation affects mood, impulse control, and the brain systems supporting these processes. Accordingly, this study tested the(More)
