Abstract

PUREZA, Janice R.; JACOBSEN, Geise M.; OLIVEIRA, Rodrigo G.  and  FONSECA, Rochele P. Relationships between executive functions tasks in late childhood. Psychol. Neurosci. [online]. 2011, vol.4, n.3, pp. 369-376. ISSN 1983-3288.  http://dx.doi.org/10.3922/j.psns.2011.3.010.

Executive functions (EF) is a general term that refers to cognitive processes designed to organize and adapt human behavior in situations that require planning and decision making, problem solving, initiation and inhibition of actions, and adapting to changes. Among the main components of executive processes, we can emphasize the ability to inhibit and to present cognitive flexibility due to changes. Understanding the relationships among the various components of EF in adults and children has been a focus in the literature. However, these processes are complex and multiple. The present study sought to determine whether correlations exist among performances measured by different tools used to evaluate EF in school-age children. The sample comprised 59 children aged 8 to 12 years attending public schools. Participants were assessed using verbal fluency tasks and narrative discourse with the Montreal Battery of Evaluation of Communication-MAC Battery, random-number generation, the Hayling Test, the Bells Test, and the n-back test. Correlation analyses were performed using Pearson's correlation coefficient. The results suggested a closer relationship among some components of the evaluation of EF, especially among tasks that assess inhibition and cognitive flexibility.
