Changes In Genetic And Environmental Influences On Trait Anxiety From Middle Adolescence To Early Adulthood, Sarah Garcia, Erin C. Tully, Nick Tarantino, Susan South, William G. Iacono, Matt Mcgue

Psychology Faculty Publications

Background: Middle adolescence to early adulthood is an important developmental period for the emergence of anxiety. Genetically-influenced stable traits are thought to underlie internalizing psychopathology throughout development, but no studies have examined changes in genetic and environmental influences on trait anxiety during this period.

Method: A longitudinal twin study design was used to study same-sex twin pairs (485 monozygotic pairs, 271 dizygotic pairs) at three ages, 14, 18, and 21 years, to examine developmental shifts in genetic and environmental effects on trait anxiety.

Results: The heritability of trait anxiety increased with age, particularly between ages 14 and 18, no significant …

Parental Distress, Parenting Practices, And Child Adaptive Outcomes Following Traumatic Brain Injury, Jackie L. Micklewright, Tricia Z. King, Kathleen O'Toole, Christopher C. Henrich, Frank J. Floyd

Psychology Faculty Publications

Moderate and severe pediatric traumatic brain injuries (TBI) are associated with significant familial distress and child adaptive sequelae. Our aim was to examine the relationship between parental psychological distress, parenting practices (authoritarian, permissive, authoritative), and child adaptive functioning 12–36 months following TBI or orthopedic injury (OI). Injury type was hypothesized to moderate the relationship between parental distress and child adaptive functioning, demonstrating a significantly stronger relationship in the TBI relative to OI group. Authoritarian parenting practices were hypothesized to mediate relationship between parental distress and child adaptive functioning across groups. Groups (TBI n=21, OI n=23) did not differ significantly on …

Neural Responses To Peer Rejection In Anxious Adolescents: Contributions From The Amygdala-Hippocampal Complex, Jennifer Y.F. Lau, Amanda E. Guyer, Erin Tone, Jessica Jenness, Jessica M. Parrish, Daniel S. Pine, Eric E. Nelson

Psychology Faculty Publications

Peer rejection powerfully predicts adolescent anxiety. While cognitive differences influence anxious responses to social feedback, little is known about neural contributions. Twelve anxious and 12 age-, gender- and IQ-matched, psychiatrically-healthy adolescents received ‘not interested’ and ‘interested’ feedback from unknown peers during a Chatroom task administered in a neuroimaging scanner. No group differences emerged in subjective ratings to peer feedback, but all participants reported more negative emotion at being rejected (than accepted) by peers to whom they had assigned high desirability ratings. Further highlighting the salience of such feedback, all adolescents, independent of anxiety levels, manifested elevated responses in the amygdala-hippocampal …

Behavioral And Neural Representation Of Emotional Facial Expressions Across The Lifespan, Leah Somerville, Fani Negar, Erin Tone

Psychology Faculty Publications

Humans’ experience of emotion and comprehension of affective cues varies substantially across the lifespan. Work in cognitive and affective neuroscience has begun to characterize behavioral and neural responses to emotional cues that systematically change with age. This review examines work to date characterizing the maturation of facial expression comprehension, and dynamic changes in amygdala recruitment from early childhood through late adulthood while viewing facial expressions of emotion. Recent neuroimaging work has tested amygdala and prefrontal engagement in experimental paradigms mimicking real aspects of social interactions, which we highlight briefly, along with considerations for future research.
