Published in: Brain and Cognition, Volume 122, April 2018, 26-33 Abstract “One of the most important structural changes that occur in the brain during the course of life relates to the corpus callosum, the largest neural pathway that connects the two cerebral hemispheres. It has been shown that the corpus callosum, and in particular its anterior […]
Published in: Cognitive, Affective, & Behavioral Neuroscience, Volume 18, Issue 1, 21-34 Abstract “We examined older adult (OA) and younger adult (YA) neural sensitivity to face trustworthiness in reward circuit regions, previously found to respond to trustworthiness in YA. Interactions of face trustworthiness with age revealed effects exclusive to OA in the amygdala and caudate, and
Published in: Memory & Cognition, Volume 46, Issue 2, 274-284 Abstract “Research into the effects of cognitive aging on route navigation usually focuses on differences in learning performance. In contrast, we investigated age-related differences in route knowledge after successful route learning. One young and two groups of older adults categorized using different cut-off scores on the

Published in: Neuropsychologia, Volume 110, February 2018, 37-43 Abstract “As we age, the architecture of cognition undergoes a fundamental transition. Fluid intellectual abilities decline while crystalized abilities remain stable or increase. This shift has a profound impact across myriad cognitive and functional domains, yet the neural mechanisms remain under-specified. We have proposed that greater connectivity between
Published in: Psychonomic Bulletin & Review, Volume 24, Issue 6, December 2017, 2021-2030 Abstract “We measured changes in self and friend biases in perceptual matching in young and older participants. Participants learned associations between neutral geometric shapes and three personal labels (You, Friend, or Stranger), representing themselves, their named best friend, and a stranger not corresponding to anyone

Published in: Cognition and Emotion, Volume 32, Issue 2, 414-421 Abstract “All lives contain negative events, but how we think about these events differs across individuals; negative events often include positive details that can be remembered alongside the negative, and the ability to maintain both representations may be beneficial. In a survey examining emotional responses to
Published in: Social Cognitive and Affective Neuroscience, Volume 13, Issue 2, 156-163 Abstract “The capacity to adaptively respond to negative emotion is in part dependent upon lateral areas of the prefrontal cortex (PFC). Lateral PFC areas are particularly susceptible to age-related atrophy, which affects executive function (EF). We used structural and functional magnetic resonance imaging (MRI)
