The COVID-19 pandemic and its preventive methods related to social isolation and quarantine have pointed to a huge change in global behavior. The perception of the hazards of the virus and contamination, as well as obligatory routine changes have impacted negatively on the well-being and mental health of people. To handle this context, humans adopt...
Risk perception is a concept related to the decision-making process and allows people to perceive the hazards surrounding the context and choose the best preventive methods to avoid them. The COVID-19 pandemic was a remarkable era in which people had to adopt protective methods, such as social isolation, to reduce the possibility of being contamina...
The Neuropsychological Test for the Assessment of Visuospatial Binding (TNABV) was developed to measure the Working Memory binding for object-location features. This study aimed to provide validity evidence related to the content and internal structure of the TNABV. To investigate the evidence based on internal structure, the sample was composed of...

Neuropsychological alterations have been identified in populations heavily exposed to metals with neurotoxic potential, such as manganese (Mn). This study examined the associations between Mn environmental exposure in school-aged children and executive functions, using structural equation modeling. Children, aged between 7 and 12 years (N = 181), w...
Direct‐acting antivirals (DAAs) have been approved in recent years to treat patients infected by the Hepatitis C virus (HCV). The DAAs treatment is well tolerated and increases sustained virological response (SVR), but there is no consensus about the neuropsychological functioning related to the treatment. This systematic review aims to provide an...
A habilidade visuoespacial é importante para a vida dos indivíduos ao longo do desenvolvimento. Prejuízos nesta habilidade podem comprometer a funcionalidade do indivíduo e esta é uma função importante em diversos casos clínicos, como desenvolvimento atípico, envelhecimento patológico e lesões cerebrais. A avaliação neuropsicológica pode auxiliar n...
The objective of this study is to evaluate cognition in patients using either ketamine or esketamine to treat TRD. We also evaluate if both ketamine and esketamine as one group influence cognition in patients with TRD. Fifty-four patients with TRD were infused with either ketamine or esketamine and were assessed at three time points: baseline, 24h,...
Este estudo tem por objetivo apresentar evidências de validade do Teste do Desempenho Atencional (TDA). Buscaram-se evidências baseadas no conteúdo, na estrutura interna e na fidedignidade. As evidências de conteúdo foram realizadas por intermédio da análise de juízes (n = 7; k = 0,84) e análise semântica (n = 12, k = 0,77), cujos resultados sugeri...
This study aims to present evidence of validity of the Attentional Performance Test
(APT). The search for evidence based on content, internal structure and reliability
was carried out. The content’s evidence was run with the expert judgement (n = 07;
k = 0.84) and semantic analysis (n = 12, k = 0.77). Their results suggested an
adequate agreement w...

The Corsi Block-Tapping Task is widely used by clinicians and researchers in Brazil
for the assessment of visuospatial working memory. The standardizations proposed by
Kessels, van den Berg, Ruis, and Brands (2008) and Kessels, van den Zandvoort,
Postma, Kappelle, and de Hann (2000) are widely reported in the national literature;
however, there are...
O TNABV é um teste neuropsicológico que visa avaliar a capacidade de binding da memória operacional visuoespacial, isto é, a associação de informações visuais e espaciais para posterior lembrança. Trata-se de uma proposta ecológica, isto é, que se aproxima da realidade dos sujeitos, considerando sobretudo o contexto em que se passa: a organização d...
Studies have demonstrated that, for urban children, dust represents the main exposure to sources of metals like lead (Pb) and manganese (Mn). We aimed to investigate the exposure to these metals and their association with intellectual deficit in children living in an industrial region. This cross-sectional study recruited volunteers from four eleme...
Introduction:
The use of ketamine as an option in the treatment of depressive disorder is growing rapidly, supported by numerous clinical trials attesting its efficacy and safety. Esketamine, the S (+) enantiomer of ketamine, is the most widely used form in the anesthetic environment in some countries, and new studies have shown that it may also b...
Excessive exposure to Mn can lead to its accumulation in the brain with neurotoxic consequences. In children, elevated Mn has been associated with deficits in certain neuropsychological domains such as cognition, motor function, memory and attention, and in some instances, hyperactivity and behavioral problems. The aim of this study was to evaluate...
Manganese (Mn) is an essential element, however high levels of Mn have been associated with lower neuropsychological performance and behavioral problems in children. We investigated the associations between hair Mn concentrations and neuropsychological and behavioral performances among children with long-term exposure to airborne Mn aged between 7...
O TAA foi desenvolvido para a mensuração do efeito binding, a integração entre diferentes informações visuais, espaciais, fonológicas e semânticas. Este é um dos processos do retentor episódico que é um subsistema do modelo multicomponente de memória operacional. Evidências vêm sugerindo que a atuação da memória de longa duração em conformidade com...
A fase adulta inicia aos 24 anos, perdurando até os 60 anos, quando o indivíduo se torna idoso. É nesse período do desenvolvimento que se espera que o indivíduo se torne independente e, perante a lei, é quando se torna capaz de responder por seus atos. Esse marco etário pode variar conforme o contexto regional e cultural. É também nesse período que...
O Código de Trânsito Brasileiro de 1997, no capítulo I, artigo 1º, define o trânsito como a utilização das vias por veículos, pessoas e animais, em grupos ou isolados, conduzidos ou não, para fins de circulação, parada, estacionamento e operação de carga ou descarga. Indo em uma direção mais atual, o DENATRAN (2008) refere o trânsito como o resulta...
