Attention to the eyes and eye contact form an important basis for the development of empathy and social competences including prosocial behavior. Thus, impairments in attention to the eyes of an interaction partner might play a role in the etiology of antisocial behavior and violence. For the first time, the present study extends investigations of eye gaze to a large sample (N = 173) including not only male but also female violent offenders and a control group. We assessed viewing patterns during the categorization of emotional faces via eye tracking. Our results indicate a reduced frequency of initial attention shifts to the eyes in female and male offenders compared to controls, while there were no general group differences in overall attention to the eye region (i.e., relative dwell time). Thus, we conclude that violent offenders might be able to compensate for deficits in spontaneous attention orienting during later stages of information processing., (Copyright © 2021 Elsevier B.V.

Recent findings suggest that adults suffering from attention deficit hyperactivity disorder (ADHD) display an atypical pattern of hemispheric asymmetry, assessed through the alpha band in resting-state electroencephalogram. In the context of the approach-withdrawal model of hemispheric asymmetry, this pattern has been identified as a correlate of approach-related behavior, particularly in anterior brain regions. The current study sought to replicate previous findings on alpha asymmetry in ADHD, and to specify them based on the assumption that ADHD represents a disorder of excessive approach tendencies. A group of ADHD patients (n=19) was compared to a group of healthy controls (n=19) on measures of alpha asymmetry and aggression, an approach-related trait. Observed region-specific group differences in alpha asymmetry approximated assumptions of the approach-withdrawal model. In addition ADHD subjects displayed elevated levels of a subcomponent of aggression. These results provide support for a conceptualization of ADHD as a disorder of excessive approach tendencies., (Copyright © 2011 Elsevier B.V. All rights reserved.)
