Does attentional focus modulate affective information processing in male violent offenders with psychopathic traits?

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 attentional focus.

Cognitive and electrophysiological markers of adult full syndrome and subthreshold attention-deficit/hyperactivity disorder.

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 neural alterations in this group. Here, we explored impairments in executive functions and their electrophysiological correlates in a sample of adults with full syndrome (N = 113) and subthreshold (N = 46) ADHD compared to controls (N = 42).

Distraction by salient stimuli in adults with attention-deficit/hyperactivity disorder: Evidence for the role of task difficulty in bottom-up and top-down processing.

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 attentional focus (indirect and direct processing of distractors) was examined.

Interpretation of ambiguous facial affect in adults with attention-deficit/hyperactivity disorder.

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 stimuli is impaired, less is known about the potential interpretation biases in ADHD which are linked to other externalizing psychopathologies. The present study investigated interpretation biases in adults with ADHD (N = 65) and controls (N = 49) using ambiguous facial stimuli (angry/happy, angry/fearful, fearful/happy blends) with different proportions of each emotion.

Neurofeedback, sham neurofeedback, and cognitive-behavioural group therapy in adults with attention-deficit hyperactivity disorder: a triple-blind, randomised, controlled trial.

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 neurofeedback) and efficiency (compared with meta-cognitive therapy) of a standard EEG neurofeedback protocol in adults with ADHD.

Processing of Dynamic Affective Information in Adults With ADHD.

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 specific emotional categories or may generalize to all basic emotions.

Temporal estimation of threatening stimuli in social anxiety disorder: investigation of the effects of state anxiety and fearfulness.

Background And Objectives: 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 understood. The present study investigated the relative contributions of these factors in a first study using clinical sample with social anxiety disorder (SAD) and healthy controls (HC).

Frontal brain asymmetry in adult attention-deficit/hyperactivity disorder (ADHD): extending the motivational dysfunction hypothesis.

Objective: Attention-deficit/hyperactivity disorder (ADHD) involves motivational dysfunction, characterized by excessive behavioral approach tendencies. Frontal brain asymmetry in the alpha band (8-13 Hz) in resting-state electroencephalogram (EEG) represents a neural correlate of global motivational tendencies, and abnormal asymmetry, indicating elevated approach motivation, was observed in pediatric and adult patients. To date, the relation between ADHD symptoms, depression and alpha asymmetry, its temporal metric properties and putative gender-specificity remain to be explored.
