Early life presence of antisocial behavior (e.g., aggression/delinquency) and psychopathic/callous-unemotional (CU) traits (lacking empathy/remorse, shallow affect) are precursors to juvenile crime and criminal offending in adulthood. Etiological research on antisocial/CU tendencies has implicated both neurobiological (e.g., alterations in brain function and structure) and environmental (social adversity, prenatal stress) underpinnings. It has been proposed that reward and punishment processing deficits may induce problematic traits and behavior, such that antisocial/CU tendencies may be linked to hypersensitivity to rewards and hyposensitivity to punishment. Studies in this area have generated inconsistent findings and focused primarily on adult and clinical samples, leaving youth and community …

Unconscious processing has been convincingly demonstrated for task-relevant feature dimensions. However, it is possible that the visual system is capable of more complex unconscious operations, extracting visual features even when they are unattended and task irrelevant. In the current study, we addressed this question by measuring unconscious priming using a task in which human participants attended to a target object's shape while ignoring its color. We measured both behavioral priming effects and priming-related fMRI activations from primes that were unconsciously presented using metacontrast masking. The results showed faster RTs and decreases in fMRI activation only when the primes were identical …
