HARP-Project 1 Cognitive Training

Emerging evidence from social neuroscience suggests that prefrontal cortex (PFC), insular and anterior cingulate cortex (ACC) regulate social and emotional responses to acute threats to social connectedness among young adults. Deficient neural reserve or overused neural compensation resulting from neurodegeneration is commonly observed in these frontal regions in old age. This aging-related "neural depletion" may have implications for how older adults respond to social threats, potentially increasing maladaptive emotional and social behavioral responses, such as social anxiety and social avoidance, which contribute to social disconnectedness. The central hypothesis is that cognitive deficits and associated aging-related 'neural depletion' in the frontal regions will contribute to maladaptive social-emotional responses to a social stressor -- social exclusion. Ultimately, maladaptive responses to acute social stress, such as social anxiety and avoidance, can compromise social connectedness by increasing social strain and isolation. The investigators have recently developed a neuroplasticity-based cognitive training program, called vision-based speed of processing (VSOP) training, targeting multiple aspects of cognitive capacity (e.g., attention, working memory and inhibition) and incorporating the speed component to improve the efficiency of these cognitive processes. VSOP training also targets several neural networks seeded in ACC and insular (default mode network) or PFC (the frontal-striatal network and central executive network). These networks also overlap with neural substrates of emotion regulation. Notably, VSOP training appears to improve emotion regulation, as depressive symptoms were reduced in older adults following VSOP training. Finally, the autonomic nervous system (ANS), critical to stress adaptation, is regulated by these frontal regions. The objective of the proposed pilot study is to provide proof-of-concept for the hypothesis that improvements in older adults' cognitive capacity, frontal regions' neural efficiency, and ANS function via the VSOP training will be associated with more adaptive social-emotional response to social exclusion, which, in turn, should confer longer-term protection for older adults' sense of social connectedness. Randomized Controlled Trial Design: 30 older adults will be randomly assigned to engage in 6-week VSOP training, or to an active control group. Differential changes from baseline to post-training in cognitive capacity, neural efficiency, and ANS function, and sense of social connectedness, will be compared between VSOP control groups. A social exclusion paradigm ('cyberball' task) will be conducted post-training to evaluate VSOP training effects on social-emotional responses to social exclusion, including anxiety and motivation for social affiliation.
