Research Environment and Opportunities<\/h2>\n

The environment at USC is an outstanding one for researchers with interests in cognitive neuroscience, emotion, decision making and aging. The USC Leonard Davis School of Gerontology<\/a> is the oldest and largest school of gerontology in the world and has long been a leader in the field, with its multidisciplinary faculty doing research in neuroscience, molecular biology, psychology, sociology, demography and public policy. The Psychology Department<\/a> and the Neuroscience Program<\/a> have outstanding faculty in cognitive and affective neuroscience. There are also faculty members and other researchers with related interests in other schools and departments across campus, such as at the law, business and medical schools.<\/p>\n

The Dornsife Imaging Center<\/a> has a research-dedicated 3T MR scanner capable of performing structural, spectroscopic and functional scans of human subjects as they view and listen to stimuli. In addition, there are peripheral devices allowing collection of eye movements, skin conductance responses, heart rate, blood pressure and respiratory rhythm. The Center also provides study preparation space, a mock scanner, and an imaging analysis laboratory. There is a full-time physicist who assists investigators with the technical details necessary to conduct studies and a full-time data analysis consultant. The Center is less than one block away from the USC Emotion & Cognition Lab.[\/vc_column_text][vc_separator][vc_column_text]<\/p>\n

Undergraduate Research Assistants<\/h2>\n

We are looking for bright and motivated USC undergraduates who are interested in learning more about the cognitive neuroscience of emotion, decision making and memory. As an Undergraduate Research Assistant in the USC Emotion & Cognition Lab, you would work closely with other members of the lab on one or more of our ongoing research projects. Your involvement would include running experiment sessions with participants, helping to enter, code and analyze data, preparing stimuli for projects and doing literature searches. There is also the opportunity to get involved in neuroimaging (fMRI) research. Research assistants typically volunteer their time or earn course credit for working in the lab, rather than being paid. Because of the training involved in becoming a research assistant in our lab, we ask for a minimum 12 hour commitment per week, usually for at least two semesters. Unfortunately, we do not have the capacity to take on research assistants who are not affiliated with USC. If you are interested in gaining research experience by working in our lab please apply with this application link<\/a>. You are also welcome to call us at 213-740-9543 or email us at matherlab@usc.edu<\/a>\u00a0for more information.[\/vc_column_text][vc_separator][vc_column_text css=””]<\/p>\n

Prospective Graduate Students<\/h2>\n

Depending on funding and program priorities, we recruit from five different Ph.D. programs at USC: <\/span>\u00a0<\/span><\/p>\n

\u00a0<\/span>\u202f<\/span>Gerontology<\/span><\/a>,\u202f<\/span>Psychology (Brain and Cognitive Science)<\/span><\/a>, Psychology (Clinical Science)<\/a>, <\/span>Neuroscience<\/span><\/a>, and Biomedical Engineering<\/a>.<\/span><\/p>\n

For your information, in the coming year, we may be recruiting from the \u202fGerontology<\/a> program but do not plan on recruiting from either of the Psychology programs. If you are interested in the Biomedical Engineering program, please contact Mara Mather to discuss the possibility. The Neuroscience Graduate Program (NGP) does not recruit candidates directly into a lab as the first year involves rotations, so to join the lab through the NGP, you would first get admitted to that program then do a rotation in our lab.\u00a0<\/span><\/p>\n

Our lab is currently working on the following research questions:<\/span>\u00a0<\/span><\/p>\n

    \n
  1. How does the brain\u2019s noradrenergic system help slow or accelerate cognitive decline in older adults?<\/span><\/b>\u00a0Pathology related to Alzheimer\u2019s disease is seen in a small nucleus in the brainstem\u2014the locus coeruleus\u2014 in most people by the time they are in their 30\u2019s\u00a0<\/span>(Braak et al., 2011)<\/span>. The locus coeruleus is the source of most of the brain\u2019s noradrenaline and initial findings suggest that it becomes hyperactive during aging and the early progression of Alzheimer\u2019s disease\u00a0<\/span>(Mather, 2021; Weinshenker, 2018)<\/span>. Using new fMRI techniques to localize and quantify the locus coeruleus, our lab was the first to identify correlations between locus coeruleus MRI contrast and cognition in cognitively healthy older adults\u00a0<\/span>(Clewett et al., 2016)<\/span>. We are currently examining how locus coeruleus structure relates to cognitive functioning\u00a0<\/span>(e.g., Dahl et al., 2019)<\/span>\u00a0and the progression of Alzheimer\u2019s disease\u00a0<\/span>(e.g., Dutt et al., 2020)<\/span>.<\/span><\/li>\n
  2. Can we intervene to optimize noradrenergic function in older adults to slow the progression of Alzheimer\u2019s disease?<\/span><\/b>\u00a0The\u00a0ultimate goal\u00a0of our research is to use emerging knowledge about the locus coeruleus\/noradrenergic system to develop interventions that prevent the progression of Alzheimer\u2019s disease in cognitive healthy older adults\u2019 brains. We have exciting preliminary data suggesting that a heart rate variability biofeedback intervention can slow the rate of hippocampal atrophy in older adults, and we currently are designing a new intervention trial to follow up on these findings and test the role of the noradrenergic system in the effects.\u00a0In\u00a0addition, we are interested in how relationships between noradrenaline\/heart rate variability and the trajectory of cognitive decline may differ in older\u00a0African-Americans, who show different relationships between heart rate variability and psychological health.<\/span><\/li>\n
  3. How do older adults\u2019 exhibit a positivity effect in despite their low heart rate variability?<\/span><\/b>\u00a0The positive psychology movement studies psychological flourishing to learn how to optimize well-being. From this perspective, emotional functioning in aging is a rich vein to tap. Older adults typically experience better moods and less of a negativity bias in attention and memory than younger adults and do so even as heart rate variability \u2014 a robust marker of psychological well-being \u2014 declines significantly. About 20 years ago, we identified a positivity effect in older adults\u2019 attention and memory\u00a0<\/span>(Charles et al., 2003; Mather & Carstensen, 2003; Mather & Carstensen, 2005)<\/span>. We currently are examining how the age-related positivity effect can occur despite<\/span> older adults’ marked declines in heart rate variability (Mather, 2023 preprint) – as lower heart rate variability is typically associated with less positive emotion.\u00a0<\/span><\/li>\n<\/ol>\n

    Our lab is committed to Open Science principles of data sharing (we have shared all our published behavioral data online since 2011) and maximizing replicability of our findings. <\/span><\/p>\n
