Antisocial and psychopathic individuals are characterized by a reduced responsivity to affective information. Yet, the role of attentional processes as possible modulator of these deficits is poorly understood. The current study investigated early and late processing of emotional stimuli in a sample of incarcerated offenders while manipulating the...

Attention-deficit/hyperactivity disorder (ADHD) has been often referred to as an executive function deficit disorder with a specific electrophysiological signature. Although previous research suggests that individuals with subthreshold symptoms also suffer from severe impairments in daily life, only few studies have investigated cognitive and neura...

In addition to impairments in cognitive functioning, attention-deficit/hyperactivity disorder (ADHD) is associated with deficits in interpersonal functioning as well which are assumed to stem from a distorted perception or interpretation of affective information. While previous research suggests that the decoding of negatively valenced facial stimu...

The cognitive mechanisms of increased distractibility in attention-deficit/hyperactivity disorder (ADHD) are poorly understood. The current study investigated the influence of two major modulating factors (emotional saliency, task difficulty) on behavioral and electrophysiological parameters underlying distractibility in ADHD. In addition, the atte...

Background: Many studies suggest that electroencephalographic (EEG) neurofeedback might be beneficial in the treatment of attention-deficit hyperactivity disorder (ADHD). However, numbers of well controlled studies are low and neurofeedback techniques are regarded as highly controversial. The present trial examined the efficacy (compared with sham...

Erwachsene mit einer Aufmerksamkeitsdefizit-/Hyperaktivitätsstörung (ADHS) fallen neben funktionellen Beeinträchtigungen (z. B. Unaufmerksamkeit) gehäuft auch durch emotionale und interpersonelle Probleme auf. Anhand von drei Studien wurde die Verarbeitung von emotionalen Informationen bei Erwachsenen mit ADHS im Vergleich zu gesunden Kontrollen un...

Objective: ADHD has been repeatedly linked to problems in social functioning. Although some theories assume that the emotion recognition deficits are explained by general attentional deficits, mounting evidence suggests that they may actually constitute a distinct impairment. However, it remains unclear whether the deficient processing affects spec...

Prior studies suggest that particularly negative emotional events tend to be experienced as temporally dilated. Perceptual characteristics of the threat cue (averted or directed angry face), state as well as individual anxiety levels have been shown to contribute to the temporal distortions, but the interplay between these factors is not well under...

Objective Attention-deficit/hyperactivity disorder (ADHD) involves motivational dysfunction, characterized by excessive behavioral approach tendencies. Frontal brain asymmetry in the alpha band (8-13Hz) in resting-state electroencephalogram (EEG) represents a neural correlate of global motivational tendencies, and abnormal asymmetry, indicating ele...
