30: Emotions, Attention, and Decision Making in the Aging Brain (with Mara Mather)

Despite the common stereotype of ‘older and crankier,’ psychologists suggest we become more positive as we age. Why? Do our aging brains become worse at detecting threats in the environment? Do we choose to focus on more positive aspects of our experience as we age? And what does the latest scientific research say about one of the major dangers of older age — Alzheimer’s disease? Mara Mather joins Igor and Charles to discuss the neuroscience of emotional aging, the role of the locus coeruleus in memory and attention, emotion-induced blindness, and the parallels between Cardiovascular disease and Alzheimer’s disease. Igor digs into the different roles of culture and the lack of good longitudinal studies of aging, Mara reveals how intense emotions can sharpen some aspects of our memories of an event while blunting others, and Charles learns that he and many others may be on the Alzheimer’s spectrum. Welcome to Episode 30.

Special Guest: Mara Mather.
