Perceived Neighborhood Social Disorder and Attitudes Toward Reporting Domestic Violence Against Women
2007
This study aims to explore the relationship between perceived neighborhood social disorder and attitudes toward reporting domestic violence against women. Data from a national representative sample ( N = 14,994) of Spaniards 18 years old and older were used. Multivariate logistic regression analysis showed that perceived neighborhood social disorder is negatively associated with attitudes toward reporting domestic violence against women. These results take into account the potential confounding effects of gender, age, socioeconomic status, perceived frequency of domestic violence against women, and size of city on reporting attitudes. Findings support the idea that to reduce and prevent do…
Age at surgery as a predictor of cognitive improvements in patients with drug-resistant temporal epilepsy
2017
Temporal lobe epilepsy (TLE) surgery is an effective procedure that can produce cognitive changes. However, the prognostic factors related with cognitive outcomes need to be better understood. The aim of the present study is to know if age at surgery is a reliable predictor of verbal memory competence and considering factors such as: hemisphere; type of surgery; pre-surgical seizure frequency; and epilepsy duration. Sixty-one typically dominant patients with drug-resistant TLE (34 with left TLE [L-TLE] and 27 with right TLE [R-TLE]) underwent a neuropsychological assessment before and a year after surgery. Results showed that R-TLE patients had better evolution in short- and long-term verba…
Task-induced deactivation in diverse brain systems correlates with interindividual differences in distinct autonomic indices
2018
AbstractNeuroimaging research has shown that different cognitive tasks induce relatively specific activation patterns, as well as less task-specific deactivation patterns. Here we examined whether individual differences in Autonomic Nervous System (ANS) activity during task performance correlate with the magnitude of task-induced deactivation. In an fMRI study, participants performed a continuous mental arithmetic task in a task/rest block design, while undergoing combined fMRI and heart / respiration rate acquisitions using photoplethysmograph and respiration belt. As expected, task performance increased heart-rate and reduced the RMSSD, a cardiac index related to vagal tone. Across partic…
'Prefrontal' cognitive performance of healthy subjects positively correlates with cerebral FDOPA influx: an exploratory [18F]-fluoro-L-DOPA-PET inves…
2006
Dopamine neurotransmission influences those cognitive processes, which are generally regarded as prefrontal cortical functions. In previous positron‐emission‐tomography (PET) studies, net blood‐brain clearance of [(18)F]‐fluoro‐l‐DOPA (FDOPA) correlated with impaired cognitive performance in patients with Parkinson's disease or schizophrenia. We hypothesized that FDOPA influx also correlates with performance of cognitive tasks associated with prefrontal functioning in healthy volunteers. The net blood‐brain clearance of FDOPA (K [Formula: see text]) was mapped in a group of 11 healthy volunteers and calculated in striatal volumes‐of‐interest. The Wisconsin‐Card‐Sorting‐Test (WCST), Stroop‐T…
Methylphenidate, modafinil, and caffeine for cognitive enhancement in chess: A double-blind, randomised controlled trial.
2017
Stimulants and caffeine have been proposed for cognitive enhancement by healthy subjects. This study investigated whether performance in chess - a competitive mind game requiring highly complex cognitive skills - can be enhanced by methylphenidate, modafinil or caffeine. In a phase IV, randomized, double-blind, placebo-controlled trial, 39 male chess players received 2×200mg modafinil, 2×20mg methylphenidate, and 2×200mg caffeine or placebo in a 4×4 crossover design. They played twenty 15-minute games during two sessions against a chess program (Fritz 12; adapted to players' strength) and completed several neuropsychological tests. Marked substance effects were observed since all three subs…
Acute Effects of High-intensity Resistance Exercise on Cognitive Function
2021
The purpose of the present study was to examine the influence of an acute bout of high-intensity resistance exercise on measures of cognitive function. Ten men (Mean ± SD: age = 24.4 ± 3.2 yrs; body mass = 85.7 ± 11.8 kg; height = 1.78 ± 0.08 m; 1 repetition maximum (1RM) = 139.0 ± 24.1 kg) gave informed consent and performed a high-intensity 6 sets of 10 repetitions of barbell back squat exercise at 80% 1RM with 2 minutes rest between sets. The Automated Neuropsychological Assessment Metrics (ANAM) was completed to assess various cognitive domains during the familiarization period, immediately before, and immediately after the high-intensity resistance exercise bout. The repeated measures …
A round peg in a square hole: strategy-situation fit of intra- and interpersonal emotion regulation strategies and controllability
2019
Although the importance of contextual factors is often recognised, research on emotion regulation strategies (ERS) has mainly focused so far on the effectiveness of ERS across situations. In the present research, we tested the strategy-situation fit hypothesis, which does not assume general effectiveness of ERS but instead stresses the importance of the congruency between ERS and the contexts in which they are used. Using a longitudinal Ambulatory Assessment dataset (
N170 response to facial expressions is modulated by the affective congruency between the emotional expression and preceding affective picture
2013
Does contextual affective information influence the processing of facial expressions already at the relatively early stages of face processing? We measured event-related brain potentials to happy and sad facial expressions primed by preceding pictures with affectively positive and negative scenes. The face-sensitive N170 response amplitudes showed a clear affective priming effect: N170 amplitudes to happy faces were larger when presented after positive vs. negative primes, whereas the N170 amplitudes to sad faces were larger when presented after negative vs. positive primes. Priming effects were also observed on later brain responses. The results support an early integration in processing o…
Cognitive and social cognitive functioning in spinocerebellar ataxia : a preliminary characterization
2006
INTRODUCTION : The spinocerebellar ataxias (SCAs), are rare neurodegenerative disorders caused by distinct genetic mutations. Clinically, the SCAs are characterised by progressive ataxia and a variety of other features, including cognitive dysfunction. The latter is consistent with a growing body of evidence supporting a cognitive as well as motor role for the cerebellum. Recent suggestions of cerebellar involvement in social cognition have not been extensively explored in these conditions. The availability of definitive molecular diagnosis allows genetically defined subgroups of SCA patients, with distinct patterns of cerebellar and extracerebellar involvement, to be tested comparatively u…
The importance of impulsivity and attention switching deficits in perpetrators convicted for intimate partner violence.
2018
It has been stated that Attention deficit hyperactivity disorder (ADHD) increases the likelihood of risky behavior such as intimate partner violence (IPV), but the cognitive mechanisms that facilitate or underlie these types of behavior remain unexplained. In this regard, several authors have established that impulsivity and inattentive symptoms might affect basic processes such as emotional decoding and set-shifting abilities, which are important processes for emotional and behavioral regulation. Hence, these symptoms entail a reduction in sensitivity to key contextual stimuli. Accordingly, the main aim of this study was to examine the involvement of impulsivity (assessed by self-reports) …
