Impulsivity mediates the association between narcissism and substance-related problems beyond the degree of substance use: a longitudinal observational study.

Background: Narcissism has been implied as a putative risk factor for substance use disorders (SUDs). However, previous research did not disentangle the degree of substance use from substance-related problems, the symptoms of SUDs. This preregistered study addressed the open question whether grandiose and vulnerable narcissism and their constituent traits convey specific SUD risk, that is, explain substance-related problems beyond the degree of use.

Psychological and neural correlates of social affect and cognition in narcissism: A multimethod study of self-reported traits, experiential states, and behavioral and brain indicators.

"Lack of empathy" is a diagnostic criterion of narcissism, but the nature of interpersonal functioning in narcissism is still being debated. Both, empathy and narcissism, are multidimensional constructs, and their relation might depend upon contextual factors. We investigated social affect and cognition in narcissism spanning self-reported traits and experiential states (Ecological Momentary Assessment) as well as behavioral and brain indicators (task-related functional magnetic resonance imaging).

Dissociating the Link of Neural Correlates of Inhibition to the Degree of Substance Use and Substance-Related Problems: A Preregistered, Multimodal, Combined Cross-sectional and Longitudinal Study.

Background: Frontal hypoactivation during inhibition is a promising phenotype for substance use disorders (SUDs), but studies comparing individuals with SUDs with unaffected individuals have reported inconsistent results. This may result from distinctive associations of neural correlates of inhibition with the degree of substance use and the severity of substance-related problems-two correlated but distinct facets of SUDs-reflecting a potentially disregarded confounding effect. This preregistered study tested whether frontal hypoactivation during inhibition is specifically linked to substance-related problems in SUDs beyond the degree of substance use.

Neural correlates of inhibitory control in relation to the degree of substance use and substance-related problems - A systematic review and perspective.

Inhibitory control deficits are associated with substance use disorders (SUDs) and considered a risk factor. Most studies compare SUD groups with unaffected individuals, although the degree of substance use might relate to inhibitory control deficits and explain group differences. This raises the question to which extent these deficits are specifically linked to substance-related problems.

Disentangling substance use and related problems: urgency predicts substance-related problems beyond the degree of use.

Background: Substance use disorders are reliably associated with high impulsivity and sensation seeking. Importantly, both precede problematic substance use, implicating them as risk factors. Individuals with substance use disorders show variable degrees of substance use (combined quantity and frequency) and substance-related problems and differ in both aspects from healthy controls.

Brain activation during social cognition predicts everyday perspective-taking: A combined fMRI and ecological momentary assessment study of the social brain.

Identifying distinct neural networks underlying social affect (empathy, compassion) and social cognition (Theory of Mind) has advanced our understanding of social interactions. However, little is known about the relation of activation in these networks to psychological experience in daily life. This study (N = 122) examined the ecological validity of neural activation patterns induced by a laboratory paradigm of social affect and cognition with respect to social interactions in everyday life.

At the Heart of Neurological Dimensionality: Cross-Nosological and Multimodal Cardiac Interoceptive Deficits.

Objective: Neurological nosology, based on categorical systems, has largely ignored dimensional aspects of neurocognitive impairments. Transdiagnostic dimensional approaches of interoception (the sensing of visceral signals) may improve the descriptions of cross-pathological symptoms at behavioral, electrophysiological, and anatomical levels. Alterations of cardiac interoception (encompassing multidimensional variables such as accuracy, learning, sensibility, and awareness) and its neural correlates (electrophysiological markers, imaging-based anatomical and functional connectivity) have been proposed as critical across disparate neurological disorders.

A multidimensional and multi-feature framework for cardiac interoception.

Interoception (the sensing of inner-body signals) is a multi-faceted construct with major relevance for basic and clinical neuroscience research. However, the neurocognitive signatures of this domain (cutting across behavioral, electrophysiological, and fMRI connectivity levels) are rarely reported in convergent or systematic fashion. Additionally, various controversies in the field might reflect the caveats of standard interoceptive accuracy (IA) indexes, mainly based on heartbeat detection (HBD) tasks.

"We Dance and Find Each Other"1: Effects of Dance/Movement Therapy on Negative Symptoms in Autism Spectrum Disorder.

The treatment of deficits in social interaction, a shared symptom cluster in persons with schizophrenia (negative symptoms) and autism spectrum disorder (DSM-5 A-criterion), has so far remained widely unsuccessful in common approaches of psychotherapy. The alternative approach of brings to focus body-oriented intervention methods based on a theoretic framework that explains the disorders on a more basic level than common theory of mind approaches. The randomized controlled trial at hand investigated the effects of a 10-week manualized dance and movement therapy intervention on negative symptoms in participants with autism spectrum disorder.
