2017 , Ramos Galarza, Carlos , Ramos V. , Jadán Guerrero, Janio , Lepe-Martínez N. , Paredes-Núñez L. , Gómez-García A. , Bolaños-Pasquel, Mónica

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.

Relationship between academic performance and the self-report of the executive performance of ecuadorian teenagers [Relação entre o desempenho escolar e funções funções executivas de adolescentes do equador] [Relación entre el rendimiento académico y el autorreporte del funcionamiento ejecutivo de adolescentes ecuatorianos]

2018 , Ramos Galarza, Carlos , Jadán Guerrero, Janio , Gómez-García A.

This article reports research findings from a study that analyzed the relationship between executive functions and academic performance of a sample of 250 high school students from Quito, Ecuador. The measures used consisted of the scale to evaluate efeco executive functions in the self-report format and the academic performance of the last academic year of the students. Two statistical analyses were conducted, the first one, correlational, suggested that the executive functions cognitive flexibility (r=-0.18, p<0.01), organization of materials (r=-0.15, p<0.01), monitoring (r=-0.22, p<0.01), initiative (r=-0.24, p<0.01), working memory (r=-0.28, p<0.01) and planning (r=-0.25, p<0.01), have a significant relationship inversely proportional to academic performance (the higher the deficit in executive functions are, the lower the academic performance is). Secondly, we performed a multiple regression analysis, considering executive functions as predictors of academic performance F(6.241)=4,96, p<0.001. The percentage of variance that executive functions explained about academic achievement (r2=0.11) is related to previous interventions and project research for training executive functions to improve academic achievement of high school students. © 2018, Fundacion para el Avance de la Psicologia.

Procastination, internet addiction, and academic performance in Ecuadorian college students [Procrastinación, adicción al internet y rendimiento académico de estudiantes universitarios ecuatorianos]

2017 , Ramos Galarza, Carlos , Jadán Guerrero, Janio , Paredes-Núñez L. , Bolaños-Pasquel M. , Gómez-García A.

This investigation analyzed the relationship between procrastination, internet addiction, and academic performance of college students. Mixed two-phase methodology was used. In the first phase, a quantitative, non-experimental, cross-sectional and correlational design was executed. The results indicate that procrastination correlates with internet addiction (r = 0.50, p = < 0.001) and students with high academic performance have a lower incidence of procrastinating behavior t(244) = -3.60, p < 0.001 and internet addiction t(244) = -2.44, p = 0.01 compared to university students with lower academic performance. In the qualitative phase, narratives were found associated with parenting style experienced, past experiences, use of cognitive functions, use of the internet, and other categories. In conclusion, the data are discussed in relation to previous research and through the integration of quantitative and qualitative results. © 2017 Universidad Austral de Chile.
