Resting-state EEG dynamics help explain differences in response control in ADHD: Insight into electrophysiological mechanisms and sex differences.

Reductions in response control (greater reaction time variability and commission error rate) are consistently observed in those diagnosed with attention-deficit/hyperactivity disorder (ADHD). Previous research suggests these reductions arise from a dysregulation of large-scale cortical networks. Here, we extended our understanding of this cortical-network/response-control pathway important to the neurobiology of ADHD.

Sensory sensitivity, intolerance of uncertainty and sex differences predicting anxiety in emerging adults.

As multiple vulnerability factors have been defined for anxiety disorders, it is important to investigate the interactions among these factors to understand why and how some individuals develop anxiety. Sensory Sensitivity (SS) and Intolerance of Uncertainty (IU) are independent vulnerability factors of anxiety, but their unique relationship in predicting anxiety has rarely been studied in non-clinical populations. The objective of this investigation was to examine the combined effects of SS and IU on self-reported anxiety in a sample of university students.

Comparison of a Web-Based Teaching Tool and Traditional Didactic Learning for In Vitro Fertilization Patients: A Preliminary Randomized Controlled Trial.

Objective: The objective of this prospective RCT was to compare the efficacy of a web-based teaching tool to traditional didactic teaching in IVF patients.

Methods: Forty women undergoing their first IVF cycle were randomly allocated to an interactive web-based teaching session or a nurse-led didactic teaching session. The primary outcome measure was participant knowledge regarding the IVF process, risks, and logistics assessed before and after the respective teaching session.

Cognitive control in the eye of the beholder: Electrocortical theta and alpha modulation during response preparation in a cued saccade task.

The oscillatory dynamics of medial frontal EEG theta and posterior alpha are implicated in the modulation of attention and cognitive control. We used a novel saccade cueing paradigm to examine whether theta and alpha are modulated by task difficulty during response preparation. After isolating and functionally classifying medial frontal and posterior alpha independent components, the EEG spectral power in these components was calculated on pro- and anti-saccade trials prior to response probes.

[Evaluation of visual-motor integration functions in children between 6-15 years of age].

Objective: Visual-motor integration skills are considered an essential domain of clinical and psycho-educational assessment. The goal of the present investigation is to provide the Turkish norms for the Beery-Buktenica Developmental Visual-Motor Integration Test (VMI-4th) for children and adolescents between the ages of 6-15 years as part of a comprehensive neuropsychological test battery.

Method: A total of 1887 children from elementary and high schools in the city of Bursa were recruited for this study.

Stage and load effects on ERP topography during verbal and spatial working memory.

Frontal-parietal neural networks play a significant role in the functional organization of visual working memory (WM). The relative contribution of material-specific information (e.g.

Independent contributions of cortical gray matter atrophy and ventricle enlargement for predicting neuropsychological impairment in multiple sclerosis.

The primary goal of this study was to investigate associations between regional gray matter (GM) atrophy and neuropsychological function in multiple sclerosis (MS), while accounting for the influence of central brain atrophy (i.e. third ventricle enlargement).

What are the roles of perfectionism and responsibility in checking and cleaning compulsions?

Empirical findings revealed that an inflated sense of responsibility has a major impact on obsessive-compulsive symptomatology (OCS). Another cognitive variable, perfectionism, is also theoretically linked to OCS. The assumption about the insufficient but necessary role of perfectionism for OCS and the view of perfectionism as a manifestation of avoidance of serious consequences led us to explore the role of an important cognitive mediator (responsibility) in this relationship.

Update on the relationships between neuropsychological dysfunction and structural MRI in multiple sclerosis.

Multiple sclerosis (MS) is a chronic inflammatory disease of the CNS, characterized by demyelination and neurodegeneration. Besides the sensory and motor deficits that are the hallmark of this disease, approximately 50% of MS patients are cognitively impaired. Over the years, structural neuroimaging has been used widely in MS patients for both diagnostic and research purposes.
