WCST and NEUPSILIN: relationships among executive functions, attention, memory and language

Abstract

This study investigated the relationship between measures of the Wisconsin Card Sorting Test (WCST)and a brief battery of cognitive functions (NEUPSILIN) with the goal of providing a better understanding of the association between executive processes and other functions. The sample included 39 people, from 14 to 61 years old, with an average education of 12.38 (SD = 3.65) years of study. The hypothesis that correlations would be moderate to strong between the measures of executive function, working memory, attention and prospective memory from NEUPSILIN and WCST scores was partially corroborated because the intensity of the correlations was below than the expected. Other correlations were also found between the WCST scores and tasks that assess semantic-episodic memory, oral language (inference processing) and writing (reading) components. Keywords: Executive functions, cognition, neuropsychology, WCST, NEUPSILIN. ResumoEste estudo investigou a relação entre medidas do WCST e de uma bateria breve de funções cognitivas (NEUPSILIN), com o objetivo de fornecer uma melhor compreensão sobre a associação entre processos executivos e demais funções. Participaram 39 pessoas entre 14 e 61 anos de idade e média de escolaridade de 12,38 (DP=3,65) anos de estudo. A hipótese de que correlações moderadas a fortes se dariam entre as medidas de funções executivas, memória de trabalho, atenção e memória prospectiva do NEUPSILIN e os escores no WCST foi parcialmente corroborada, porque a intensidade das correlações foi inferior ao previsto. Também foram encontradas correlações entre escores do WCST e tarefas que mensuram componentes de memória episódico-semântica, linguagem oral (processamento inferências) e escrita (leitura).

Effectiveness of executive function training on mental set shifting, working memory and inhibition in healthy older adults: A double‐blind randomized controlled trials

“…The greater the score, the better the performance. It indicates insight about the correct principle of cards combination (Greve et al., ; Yates et al., ).…”

Does tramadol dependence impair cognitive functions?

“…Patients showed more nonpreservative errors in comparison to controls, which indicated difficulties in forming concepts and having insights, even with flexible answers. Also, patients showed lower scores in conceptional level response, indicating poor insight about the correct principle of the cards’ combination (Yates et al , 2013).…”

Executive Functioning and Problem Solving: A Bidirectional Relation

“…Cinan et al [15] shed light on the interplay between the central executive and the phonological loop through manipulating the Wisconsin Card Sorting Test. The executive systems responsible for the different types of executive functions involve the phonological loop and the visuospatial sketchpad.…”
