Callous-unemotional (CU) traits in antisocial youth have been associated with deficits in the processing of emotionally distressing stimuli in a number of past studies. In the current study, we investigated moderators of this association in a sample of 88 ethnically diverse detained boys (mean age = 15.57, SD = 1.28). Overall, emotional processing of distressing stimuli using a dot-probe task was not related to CU traits and there was no moderating effect of ethnicity. However, CU traits were related to deficits in emotional processing in youth high on aggression and youth high on exposure to community violence. Further, youth high on CU traits but with enhanced orienting to distressing stimuli had stronger histories of abuse, supporting the possibility that there may be environmentally influenced pathways in the development of these traits.

The role of inhibition in the processing of peripheral cues.

The present study investigated the role of inhibition in peripheral cueing by nonpredictive cues. Based on past findings, we investigated the possibility that inhibition of learned irrelevant cue colors is typical of short cue-target intervals, with more competition for attention capture between cue versus target. In line with the expectation, in a modified contingent-capture protocol, with short cue-target intervals, we found same-location costs (SLCs) - that is, disadvantages for validly cued targets (cue = target position) compared to invalidly cued targets (cue ≠ target position) with consistently colored non-matching cues.

Schizophrenia (SZ) is a chronic neuropsychiatric disorder characterized by disturbances in cognitive, perceptual, social, emotional, and behavioral functions. The conventional SZ diagnosis relies on subjective assessments of individuals by psychiatrists, which can result in bias, prolonged procedures, and potentially false diagnoses. This emphasizes the crucial need for early detection and treatment of SZ to provide timely support and minimize long-term impacts.

Obsessive-compulsive disorder (OCD) and anxiety disorders are early-onset mental disorders characterized by selective attention and strong emotional reactions. Attentional bias has been proposed to play a role in the development, onset, and maintenance of the disorders, but few studies have included youth with mental disorders, and no study has included more than one clinical group, making it unclear whether biased attention is disorder-specific or transdiagnostic in nature. In the present study, 65 youths with OCD (M = 13.

Individual differences in how the brain responds to novelty are present from infancy. A common method of studying novelty processing is through event-related potentials (ERPs). While ERPs possess millisecond precision, spatial resolution remains poor, especially in infancy.
