“…The presence of practice effects in healthy samples has made estimating reliability on this task difficult. One study published in Brazil specifically addressed a test-retest reliability of the IGT in healthy individuals and noted 'moderately positive correlations' for Blocks 4 and 5 but weaker relationships in the earlier blocks (Cardoso et al, 2010). In an effort to address the issue of stability in our BD sample, we conducted secondary analyses restricted to the BD sample, to illustrate that as a group (all BD subjects) there is relative stability of performance on Blocks 4 and 5 of the IGT (ICC ¼ 0.49; p ¼ 0.03).…”

We recently reported that the D2/D3 agonist pramipexole may have pro-cognitive effects in euthymic patients with bipolar disorder (BPD); however, the emergence of impulse-control disorders has been documented in Parkinson's disease (PD) after pramipexole treatment. Performance on reward-based tasks is altered in healthy subjects after a single dose of pramipexole, but its potential to induce abnormalities in BPD patients is unknown. We assessed reward-dependent decision making in euthymic BPD patients pre-and post 8 weeks of treatment with pramipexole or placebo by using the Iowa Gambling Task (IGT). The IGT requires subjects to choose among four card decks (two risky and two conservative) and is designed to promote learning to make advantageous (conservative) choices over time. Thirty-four BPD patients completed both assessments (18 placebo and 16 pramipexole). Baseline performance did not differ by treatment group (F ¼ 0.63; p ¼ 0.64); however, at week 8, BPD patients on pramipexole demonstrated a significantly greater tendency to make increasingly high-risk, high-reward choices across the five blocks, whereas the placebo group's pattern was similar to that reported in healthy individuals (treatment Â time Â block interaction, po0.05). Analyses of choice strategy using the expectancy valence model revealed that after 8 weeks on pramipexole, BPD patients attended more readily to feedback related to gains than to losses, which could explain the impaired learning. There were no significant changes in mood symptoms over the 8 weeks, and no increased propensity toward manic-like behaviors were reported. Our results suggest that the enhancement of dopaminergic activity influences risk-associated decision-making performance in euthymic BPD. The clinical implications remain unknown.

“…Individuals are unaware as to which decks are advantageous or disadvantageous, so that, in order to successfully perform the task, individuals must learn to avoid the disadvantageous decks based on the emotional feedback (somatic markers) produced during the task. The instrument was adapted for use in the Brazilian population (Malloy-Diniz et al, 2008;Schneider & Parente, 2006), and has been found to be both a valid (Carvalho et al, 2012) and reliable (Cardoso et al, 2010) tool for the assessment of decision making in this population. Wilson, Cockburn, & Baddeley, 1985).…”

Contributions of the ecological approach to the neuropsychology of executive functions

Neurocognitive assessment involves several different types of processes, techniques and instruments. Traditionally, clinical and/or standardized methods have been the most extensively used in neuropsychological research and clinical practice. Ecological instruments are characterized by the standardized administration of tasks with similar cognitive demands to those observed in everyday situations. Although executive functions are often required in daily living tasks, the lack of a consensus as to their theoretical defi nition has posed several hurdles to their assessment and rehabilitation. The aim of this paper was to present the contributions of an ecological neuropsychological approach to assessment, rehabilitation, and neuroimaging, while discussing the theoretical implications of these processes on the neuropsychology of executive functions. This was achieved through a non-systematic review of classical and contemporary literature on ecological assessment tools. The use of an ecological approach has contributed to the understanding and assessment of functional impairment, as well as to the development of rehabilitation programs focusing on practical daily living activities, allowing for a clearer understanding of the neural correlates of complex environmental and individual factors, and for a more thorough reassessment of the validity of theoretical models of executive functions .

“…A avaliação das funções executivas (FE) tem recebido forte ênfase na literatura nacional em Neuropsicologia e Psicologia Cognitiva, resultado dos esforços e produções de grupos de pesquisa dedicados à área (Barros & Hazin, 2013;Cardoso et al, 2010;Carreiro et al, 2014;Seabra & Dias, 2012;Natale, Teodoro, Barreto, & Haase, 2008). As funções executivas (FE) configuram um domínio cognitivo complexo relacionado com o estabelecimento de comportamentos dirigidos a metas predefinidas, envolvendo as habilidades de planejamento, flexibilidade mental, inibição e memória de trabalho (Miyake et al, 2000).…”

ResumoO objetivo do estudo foi traduzir, adaptar e investigar propriedades psicométricas da Childhood Executive Functioning Inventory (CHEXI) em uma amostra de crianças brasileiras. Após tradução, adaptação transcultural, retrotradução e equivalência semân-tica, realizada por juízes da área, a versão brasileira da CHEXI foi respondida por pais e professores de 408 crianças, idades entre 4 e 7 anos, também avaliadas com a Escala de Maturidade Mental Colúmbia e SNAP-IV. Elevados índices de consistência interna foram encontrados. A análise fatorial exploratória gerou dois fatores para a versão brasileira: um fator mais geral de funções executivas e um específico de inibição. As pontuações nas subescalas de planejamento, regulação e, marginalmente, memória de trabalho da CHEXI explicaram de modo significativo o indicador de desatenção da SNAP-IV, enquanto a pontuação na subescala de inibição explicou o indicador de hiperatividade/impulsividade. Os resultados fornecem bons parâmetros psicométricos para a CHEXI, além de contribuir para a realização de estudos com funções executivas e indicadores de TDAH no país. Palavras-chave: avaliação psicológica, neuropsicologia, função executiva, transtorno do déficit de atenção com hiperatividade Childhood Executive Functioning Inventory: adaptation and psychometric properties of the Brazilian version AbstractThe aim of the study was to translate, adapt and investigate psychometric properties of Childhood Executive Functioning Inventory (CHEXI) for a sample of Brazilian children. After translation, cultural adaptation, back-translation and semantic equivalence performed by area judges, the Brazilian version of CHEXI was answered by parents and teachers of 408 children aged between 4 and 7 years, also evaluated with the Columbia Mental Maturity Scale and SNAP-IV. High internal consistency indices were found. Exploratory factor analysis yielded two factors for the Brazilian version: a more general factor of executive functions and one specific factor of inhibition. The scores on the subscales of planning, regulation and marginally working memory in CHEXI explained significantly the inattention indicator of SNAP-IV, while the score on the inhibition subscale explained the indicator of hyperactivity/impulsivity. The results provide good psychometric parameters for CHEXI, besides contributing to the studies with Executive functions and ADHD signs in Brazil.
