Adolescent girls are at increased risk for depression, which is thought to result from the interaction of biological vulnerabilities and life stressors common to adolescent girls. A blunted late positive potential (LPP) to emotional stimuli (i.e., pleasant and unpleasant) has been associated with depressive symptoms and risk. The current study of adolescent girls examines the moderating effects of the LPP, a candidate biomarker of depression, of the link between life stress and increases in depr...

Abstract Affective personality traits, such as extraversion and neuroticism, are associated with individual differences in reward system functioning. The reward positivity (ΔRewP) is an event-related potential (ERP) component that indexes sensitivity to reward, and can be elicited by feedback indicating monetary gains relative to losses. In a sample of 508 adolescent girls, the current study examined the relationship between extraversion, neuroticism, and their respective facets and the ΔRewP. R...

The current article discusses assertiveness training, a once highly popular area of investigation that has been neglected in recent years by the field of psychotherapy. A substantial body of research indicates that assertiveness is a relevant factor associated with a variety of clinical problems, populations, and contexts, and that assertiveness training is a valuable transdiagnostic intervention. Despite its demonstrated importance, research on assertiveness and assertiveness training as a stan...

Abstract The error-related negativity (ERN) is a response-locked component in the event-related potential observed as a negative deflection 50–100 ms following the commission of an error. An unpredictable context has been shown to potentiate amygdala activity, attentional bias toward threat, and the ERN in adults. However, it is unclear whether the impact of unpredictability on the ERN is also observed in children and adolescents. In a sample of 32 9–17 year-old participants, we examined the inf...

The ability to differentiate between rewards and losses is critical for motivated action, and aberrant reward and loss processing has been associated with psychopathology. The reward positivity (RewP) and feedback negativity (FN) are ERPs elicited by monetary gains and losses, respectively, and are promising individual difference measures. However, few studies have reported on the psychometric properties of the RewP and FN—crucial characteristics necessary for valid individual difference measure...

Mounting evidence suggests that the ability to regulate emotion is crucial for psychological well-being. However, one important limitation of prior emotion regulation studies is that they rely on standardized stimuli low in personal relevance. To address this limitation, the current study employed a novel event-related potential (ERP) paradigm designed to investigate the late positive potential (LPP) as a measure of emotional reactivity and regulation to idiographic stimuli in 49 young adults. T...
