Enhanced inhibitory control during re-engagement processing in badminton athletes : An event-related potential study
2019
Highlights • Reaction time and event-related potentials of inhibitory control were compared in badminton experts and nonathletes. • Badminton experts showed enhanced inhibitory control and more efficient neural mechanisms. • Badminton experts performed better inhibitory control processing in re-engagement. • The re-engagement processing better demonstrated altered brain activity in badminton experts.
The effects of electrodermal lability and stimulus intensity on skin conductance habituation: A preliminary report
1981
A between-subjects design (N=60) was used to investigate the effects of electrodermal lability and auditory stimulus intensity on habituation of the skin conductance response (SCR). Subjects were subdivided into “labile” and “stabile” groups on the basis of frequency of nonspecific electrodermal responses during the prestimulation period. They received 20 presentations of a 1,000-Hz tone of 15, 35, 55, 75, 95, or 110 dB. There were significant effects of stimulus intensity on all three habituation measures (number of trials to habituation, reciprocal of SCR frequency to the first 10 stimuli, slope of the regression of SCR amplitude on log stimulus number). Additionally, significant effects …
Developmental dyslexia: atypical cortical asymmetries and functional significance
2000
Using brain magnetic resonance imaging, we measured in 16 young developmental dyslexic adults and 14 age-matched controls cortical asymmetries of posterior language-related areas, including Planum temporale and parietal operculum cortical ribbon, and of the inferior frontal region related in the left hemisphere to speech processing. In addition, we assessed the sulcal morphology of the inferior frontal gyrus in both groups according to a qualitative method. The dyslexic subjects also performed specific tasks exploring different aspects of phonological and lexical-semantic processes. Results showed that: (1) contrary to most results reported in the literature, there is a lack of any morpholo…
A systematic review of neuropsychiatric symptoms in mild cognitive impairment.
2009
Mild cognitive impairment (MCI) is a clinical concept proposed as an intermediate state between normal aging and dementia. This condition has multiple heterogeneous sources, including clinical presentation, etiology, and prognosis. Recently, the prevalence and associated features of neuropsychiatric symptoms (NPS) in MCI have been described. We systematically searched the PubMed database (last accessed on August 31, 2008) for articles on NPS in MCI. Included articles used strict selection criteria, and outcome variables were extracted in duplicate; of the 27 articles included, 14 (52%) used prospective cohorts. The global prevalence of NPS in MCI ranged from 35% to 85%. The most common beha…
Anger Weakens Behavioral Inhibition Selectively in Contact Athletes.
2018
Studies have increasingly found that the aggression level of contact athletes is higher than that of non-athletes. Given that higher aggression levels are associated with worse behavioral inhibition and that athletes show better behavioral inhibition than non-athletes, it is unclear why contact athletes would exhibit higher aggression levels. Emotion, especially anger, is an important factor in the generation of aggressive behavior, and anger has been shown to affect behavioral inhibition. Thus, the present study examined the influence of anger on behavioral inhibition in contact athletes. An implicit emotional Go/No-go task was used that contained 50 anger-associated words and 50 neutral w…
Substanz-bezogene Störungen: Auf dem Weg zu ICD-11 und DSM-V
2006
The development of substance abuse disorders (SUD) for DSM-V is put into perspective according to an expert meeting organized by APA and chaired by M.A. Schuckit and J.B. Saunders. Substantial compatibility with ICD-11 of WHO was expected to be achieved. A dependence syndrome, a non-dependence category as well as a subthreshold condition is supposed to be included in the SUD section in DSM-V. Categorical criteria will possibly be supplemented by dimensions conceptualized as quantitative formulations of criteria content. General and substance-specific criteria may be included for dependence. The comorbidity problem requires more research to separate substance-induced from substance-independe…
Precuneus and insular hypoactivation during cognitive processing in first-episode psychosis: Systematic review and meta-analysis of fMRI studies
2020
Abstract Introduction The neural correlates of the cognitive dysfunction in first-episode psychosis (FEP) are still unclear. The present review and meta-analysis provide an update of the location of the abnormalities in the fMRI-measured brain response to cognitive processes in individuals with FEP. Methods Systematic review and voxel-based meta-analysis of cross-sectional fMRI studies comparing neural responses to cognitive tasks between individuals with FEP and healthy controls (HC) according to PRISMA guidelines. Results Twenty-six studies were included, comprising 598 individuals with FEP and 567 HC. Individual studies reported statistically significant hypoactivation in the dorsolatera…
Psychosis, Need Adapted treatment, and psychiatrists' agency
2013
Background: In the Need-Adapted approach (NAA) therapy meetings are a deliberate effort to bring all meaningful parties and views to a common discussion prior to decisions; this constitutes a challenge for psychiatrists’ agency. Aims: To describe how psychiatrists see their agency in NAA. Methods: Using videos of co-research interviews, stimulated-recall interviews of 10 interviewees were conducted and transcribed verbatim. The material was analyzed via an adapted dialogical-narrative analytical method. Results: Institutional forces were experienced as having an enormous impact on psychiatrists’ agency, especially in the inpatient setting, reducing professional creativity. In the outpatient…
The Role of Magnetic Resonance Imaging in Central Hearing Deficits: Beyond the Acoustic Schwannoma
1997
Acoustic schwannoma is assumed to be the most common cause of sensory-neural hearing loss (SNHL), and many papers have described the role of magnetic resonance imaging (MRI) in the diagnosis of cerebello-pontine angle (CPA) tumours, particularly schwannoma. We retrospectively examined 72 patients complaining of different clinical syndromes and SNHL or different kinds of acoustic impairment who underwent MRI brain study excluding the presence of acoustic schwannoma and other CPA masses. In conclusion, although acoustic schwannoma is the most common cause of acquired HD, a lesion involving the neural centers of the acoustic pathway can also determine SNHL or HD. Considering the high sensitiv…
Normierung und Evaluation der Messinvarianz der 8-Item-Kurzform der Center of Epidemiological Studies-Depression Scale (CES-D-8)
2020
Measurement invariance and normative data of the 8-item short form of the Center of Epidemiological Studies-Depression Scale (CES-D-8) Objectives: Female gender is a risk factor for depression. It is questionable whether a given psychometric instrument depicts depressive symptom severity in men and women alike. Therefore, we examined measurement invariance of the Center of Epidemiological Studies Depression Scale-8 (CES-D-8) between women, men and different age groups. Additionally, we aimed providing normative data for CES-D-8. Methods: We assessed depressive symptoms in a German population-based sample (N = 2,507) with the CES-D-8. Gender-distorted items were excluded in the short form. R…
