    "Among neurodevelopmental disorders, attention deficit hyperactivity disorder (ADHD) is the main cause of school failure in children. Notably, visuospatial dysfunction has also been empha sized as a leading cause of low cognitive performance in children with ADHD. Consequently, the present study aimed to identify ADHD-related changes in electroencephalography (EEG) characteris tics, associated with visual object processing in school-aged children. We performed Multichannel EEG recordings in 16-year-old children undergoing Navon’s visual object processing paradigm. We mapped global coherence during the processing of local and global visual stimuli that were consistent, inconsistent, or neutral. We found that Children with ADHD showed significant differences in global weighted coherence during the processing of local and global inconsistent visual stimuli and longer response times in comparison to the control group. Delta and theta EEG bands highlighted important features for classification in both groups. Thus, we advocate EEG coherence and low-frequency EEG spectral power as prospective markers of visual processing deficit in ADHD. Our results have implica tions for the development of diagnostic interventions in ADHD and provide a deeper understanding of the factors leading to low performance in school-aged children".

    Efecto del método dirigido del dibujo sobre las habilidades visuoespaciales de preescolares
    (Benemérita Universidad Autónoma de Puebla, 2015-02) Hermosillo Abundis, Ana Cristina; HERMOSILLO ABUNDIS, ANA CRISTINA; 392344; MENDEZ BALBUENA, IGNACIO; 35799; SOLOVIEVA, YULIA; 25207
    "El presente estudio se realizó con la intención de conocer el efecto de un método formativo del dibujo sobre las funciones visuoespaciales en preescolares. Actualmente se considera que las funciones visuoespaciales comprenden diversas habilidades en todos los planos desde el concreto hasta el lógico-verbal, y que la formación adecuada de dichas funciones contribuye de manera importante a la actividad intelectual y cotidiana de toda persona. La cultura en la que estamos inmersos influye de forma dialéctica sobre el desarrollo y organización de los diferentes sistemas funcionales cerebrales. Dado que el dibujo es considerado como una habilidad visuoespacial compleja, se espera que un método formativo del dibujo siendo producto de la cultura favorezca la formación de las habilidades visuoespaciales en los preescolares. Para medir el efecto del método formativo del dibujo se utilizó un paradigma de procesamiento jerárquico que fue aplicado a preescolares divididos en dos rangos de edad (4.8 a 5.8 años y 5.9 a 6.9 años) y subdivididos en grupo control y grupo experimental. Se midieron los tiempos de reacción y la precisión ante las diferentes combinaciones posibles entre condiciones local y global y estímulos coherentes e incoherentes."

    "The aim of the present work was to investigate the use of verbal language applied to the solution of inverse function problems in comparison to the algebraic method in students of humanities. We consider only algebraic functions in our study. Three precalculus problems were chosen and two solution methods used. A total of 120 students participated in this study, half of them used the verbal method and the other half the algebraic method. To determine if there was a relationship between the utilized method and the effectiveness of the solution, that is the number of exercises solved correctly related to the type of method used, we used Pearson’s chi-square test. We found a significant association between the type of method and the success of the solution χ2 (1) = 10.84, p < 0.001. Regarding the effect size, we found that the probability to get a correct solution was 3.75 times higher when solved with the verbal method in comparison to the algebraic method. The results of the present study showed that verbal language applied to the solution of inverse function problems is highly effective when compared to the algebraic method".
