This article presents three concepts that are fundamental in the neuropsychological theoretical: (a) historical data in the study of the human brain, (b) neuropsychological evaluation of brain functions and (c) neuropsychological rehabilitation of brain functions. As relevant data in the theoretical development of the study of the human brain is a tour of the trepanation acts performed hundreds of years ago, the contributions of phrenology, the masterful findings of Broca and Wernicke, the heuristic contribution of Luria and the current revolution with the neuro-image. In the neuropsychological evaluation of brain functions, the role of specific, non-specific and delayed observation tests in the interpretation of the neuropsychological state of the human being is analyzed, which allow analyzing neuropsychological functions in the laboratory and in real lifeactivities. Finally, we analyze the process of neuropsychological rehabilitation of brain functions, where mention is made of the processes of restoration, compensation, substitution, activation-stimulation and integration, which are very useful when intervening in a brain that has suffered an acquired damage. It is concluded that the current accelerated pace has determined the advance of neuroscience, where technology and the forceful scientific contribution propose new techniques and theories to understand the processes of evaluation and rehabilitation of brain functioning.

The role of executive functions in academic performance and behaviour of university students

2020 , Ramos Galarza, Carlos , Acosta-Rodas P. , Bolaños-Pasquel, Mónica , Lepe-Martínez N.

Purpose: The purpose of this paper is fourfold: first, to analyse the relationship between executive functions and academic performance; second, to identify the level of prediction executive functions have on academic performance; third, to determine the correlation between executive functions and academic performance; and fourth, to compare executive functions based on the level of academic performance. Design/methodology/approach: The sample composed of 175 university students aged between 18 and 36 years (M=21.49, SD=3.22). The EFECO scale, the average student grade and a scale based on the diagnostic criteria for ADHD were used as measurement instruments. Findings: Difficulties in executive functions: Difficulties in working memory (r=−0.30, p=<0.01) and difficulties in conscious supervision of behaviour (r=−0.29, p⩽0.01) have an inversely proportional relationship to academic performance (the greater the deficit of executive functions, the lower the academic performance). The regression analysis showed that executive functions explain 31 per cent of the variance of academic performance (χ2(25)=43.81, p <0.001). The study found that there is a relationship between all the executive functions and students’ behaviour in a medium to large magnitude. Research limitations/implications: A limitation of this study was the size of the sample as it is not representative of the country. Nevertheless, the correlation among the variables studied here has the necessary magnitude for the proposed correlations to be found. Nonetheless, it is necessary that we perform a study with a larger number of participants in order to achieve adequate extrapolation of the results. Practical implications: Data found in this study suggest that low academic performance of university students is related to a lower functionality of their executive functions. Originality/value: The originality of the research lies in relating specific concepts of neuropsychology to explain the academic performance of university students. The research findings allow us to project new studies to improve the executive functions for the benefit of the university student. © 2019, Emerald Publishing Limited.

The role of inhibitory control in the ability to solve problems of university students

2020 , Ramos Galarza, Carlos , Acosta-Rodas P. , Ortiz-Granja D. , Lepe-Martínez N. , Valle M.D. , Ramos V. , Bolaños-Pasquel, Mónica

The aim of the present study was to analyze the role of inhibitory control in the ability to solve problems of university students. The sample consisted of 90 young people with typical development (Mage= 20.58, SD= 1.27), 39 females (43.33%) and 51 males (56.7%). The Stroop and the Anillas' Test tasks were applied as instruments. As results, it was found a directly proportional and predictive relationship between inhibitory control and problem-solving of university students (correlation between: r= .34 and .47, p= <.01; prediction: r2= .14, F(1,88)= 13.88, p= <.01). It concludes by reflecting on the contribution of conscious control to solve problems faced by the university student on a day-to-day basis in an efficient way and invites future research in order to train inhibitory control. © 2020 Fundacion para la difusion neurologica en Ecuador - FUNDINE.
