“…picking up the wrong object) or Room Error (going into the wrong room). This general principle of awarding points for task completions and subtracting them for rule breaks has also been used with other tests of multitasking (e.g., Burgess et al, 2000;Mackinlay et al, 2006). The Multitasking in HF-ASD using the Virtual Errands Task 13 maximum possible score on the VET was 10, if a participant completed all the errands and made no errors.…”

“…The Battersea Multitask Paradigm was composed of three interleaved tasks (sorting, counting and colouring) that had to be completed in three minutes. This test generated six dependent measures based on the Greenwich Multitask Paradigm (Burgess, Veitch, Costello & Shallice, 2000), and these measures broke down performance into a six-stage invariant sequence (Rule Learn, Plan, Perform, Plan Follow, Monitor, Rule Memory). Mackinlay et al found that the ASD Multitasking in HF-ASD using the Virtual Errands Task 5 group were significantly poorer in Plan and Perform, but there were no group differences in the four other stages (although the trend was in the direction of poorer performance in the HF-ASD group).…”

“…However, it is not clear whether it is important in hypothesis generation in general (Strange et al, 2001) or whether it operates in more specific conditions such as when it is necessary to integrate the outcomes of more than one inference (Ramnani and Owen, 2004;Koechlin and Hyafil, 2007). Yet another possibility is that FPC is involved in maintaining a rule active before it becomes familiar; this would fit with its known role in intention maintenance (Burgess et al, 2000(Burgess et al, , 2001 and branching (Koechlin et al, 1999).…”

Despite the recent interest in the neuroanatomy of inductive reasoning processes, the regional specificity within prefrontal cortex (PFC) for the different mechanisms involved in induction tasks remains to be determined. In this study, we used fMRI to investigate the contribution of PFC regions to rule acquisition (rule search and rule discovery) and rule following. Twenty-six healthy young adult participants were presented with a series of images of cards, each consisting of a set of circles numbered in sequence with one colored blue. Participants had to predict the position of the blue circle on the next card. The rules that had to be acquired pertained to the relationship among succeeding stimuli. Responses given by subjects were categorized in a series of phases either tapping rule acquisition (responses given up to and including rule discovery) or rule following (correct responses after rule acquisition). Mid-dorsolateral PFC (mid-DLPFC) was active during rule search and remained active until successful rule acquisition. By contrast, rule following was associated with activation in temporal, motor, and medial/anterior prefrontal cortex. Moreover, frontopolar cortex (FPC) was active throughout the rule acquisition and rule following phases before a rule became familiar. We attributed activation in mid-DLPFC to hypothesis generation and in FPC to integration of multiple separate inferences. The present study provides evidence that brain activation during inductive reasoning involves a complex network of frontal processes and that different subregions respond during rule acquisition and rule following phases.

Behavioural Assessment of the Dysexecutive Syndrome (BADS): Adaptação e Evidências de Validade

et al. 2016

ResumoAs funções executivas são habilidades que permitem um indivíduo direcionar seu funcionamento cognitivo, comportamental e emocional a metas. Para avaliá-las existem poucos instrumentos ecologicamente válidos. Para superar essa limitação, foi desenvolvida a Behavioural Assessment of the Dysexecutive Syndrome (BADS). O objetivo deste estudo foi adaptar e investigar evidências de validade de conteúdo da BADS para o contexto brasileiro. Foram realizadas três traduções do instrumento, sintetizadas em uma única versão e encaminhada a três juízes. Posteriormente, a BADS foi submetida a um grupo focal (5 adultos saudáveis) e estudo-piloto (amostra clínica com 40 pacientes neurológicos, portadores de Parkinson). O cálculo do coeficiente de validade de conteúdo total foi considerado aceitável (> 0,80); e a média do coeficiente kappa para os subtestes foi de 0,55, e para o questionário foi de 0,75, moderado e sólido, respectivamente. Os dados sugerem que a BADS está apta a ser utilizada em novos estudos para a investigação de outras propriedades psicométricas, como validade de construto, fidedignidade e normatização. Palavras-chave: funções executivas, síndrome disexecutiva, validade Behavioral Assessment of the Dysexecutive Syndrome (BADS): Adaptation and Validity Evidence AbstractExecutive functions are skills that allow an individual to direct their cognitive, behavioral and emotional functioning to goal achievement. In order to evaluate them, there are few ecologically valid instruments. Behavioral Assessment of the Dysexecutive Syndrome (BADS) was developed to overcome this limitation. The objective of this study was to adapt and investigate BADS content validity for the Brazilian context. Three translations of the instrument from English into Portuguese were done, and were later synthesized into a single version to be sent to three judges. Subsequently, BADS was applied to a focus group (5 healthy adults) and a pilot study (40 clinical neurological patients, with Parkinson's Disease). The calculation of the total content validity coefficient was considered acceptable (> 0.80); and the average coefficient kappa subtests was 0.55 and the survey was 0.75, moderate and solid, respectively. The data suggest that BADS can be used in further studies to investigate other psychometric properties as construct validity, reliability and standardization.
