Abstract The pubertal period is a time of rapid increase in the incidence of anxiety disorders, and thus, pubertal hormones may play a role in the precipitation of anxious psychopathology. DHEA, a steroid hormone that surges in adolescence, has been previously linked to anxiety, although the direction of this effect has been mixed. Using a cross-sectional design in a sample of 286 adolescent girls, the present study examined associations between salivary DHEA concentrations and self-report and i...

A recent study by Tsypes, Owens, and Gibb (2019) found that children with recent suicidal ideation had blunted neural reward processing, as measured by the reward positivity (RewP), compared to matched controls, and that this difference was driven by reduced neural responses to monetary loss, rather than blunted neural response to monetary reward. Here, we aimed to conceptually replicate and extend these findings in two large samples of children and adolescents (n = 275 and n = 235). Results fro...

: The late positive potential (LPP) is characterized by temporal and spatial changes across development-though existing work has primarily relied on visual or statistical comparisons of relatively few electrodes and averaged activity over time. The current study used an empirically based approach to characterize temporal and spatial changes in ERPs over time. Data were utilized from a large longitudinal study (N = 380) in which the LPP was recorded to pleasant, neutral, and unpleasant pictures a...

Abstract While psychosocial risk factors for peripartum depression are well-researched, studies on neural risk factors are scarce. Previous studies suggest a blunted neural response to reward may be a biomarker of depression and risk. In a sample of 86 pregnant women, the present study examined whether a reduced Reward Positivity (RewP), an event-related potential (ERP) elicited to feedback indicating monetary reward, relates to greater antenatal depressive symptoms. We also examined whether the...

Abstract The menstrual cycle is known to impact mood and cognitive function and has been shown to lead to variability in symptoms of obsessive-compulsive disorders and anxiety. Using a within-subject design, the present study examined ovarian hormones, the error-related negativity (ERN), and self-reported checking symptoms in both the mid-follicular and mid-luteal phases of the menstrual cycle. ERN amplitude and checking symptom severity did not vary between the follicular and luteal phases. How...

Abstract Adolescence is frequently described as a developmental period characterized by increased sensitivity to rewards. However, previous research on age-related changes in the neural response to gains and losses have produced mixed results, with only some studies reporting potentiated neural responses during adolescence. The current study examined the ERP responses to gains and losses during a simple monetary reward (i.e., Doors) task in a large and longitudinal sample of 248 adolescent femal...

: The menstrual cycle impacts mood and neural response to reward-phenomena that may be related to natural fluctuations in ovarian hormones. Using a within-subject design, the present study examined ovarian hormones (i.e., estradiol and progesterone) and ERPs in response to feedback indicating gains and losses in both the follicular and luteal phases of the menstrual cycle. We examined whether hormone levels and variation in neural response to reward and loss across menstrual cycle phases were as...

Abstract The Reward Positivity (RewP) is an event-related potential (ERP) potentiated to monetary gains and reduced to monetary losses. Recently, competing data suggest that more salient outcomes elicit a positivity relative to less salient outcomes, regardless of valence. However, all previous work testing the impact of salience on the RewP have examined expected versus unexpected outcomes. In the current study, participants completed the same gambling task twice in which feedback was equally p...
