    ADHD children outperform normal children in an artificial grammar implicit learning task: ERP and RT evidence
    (ACADEMIC PRESS INC ELSEVIER SCIENCE, 2010) Rosas, Ricardo; Ceric, Francisco; Tenorio, Marcela; Mourgues, Catalina; Thibaut, Carolina; Hurtado, Esteban; Teresa Aravena, Maria
    This study focuses on Implicit learning (IL) in children One of the main debates in this field concerns the Occurrence of IL indicators in experimental settings and its manifestation in different populations In this research, we are looking for evidence of the occurrence of IL in normal children and in children with Attention Deficit Hyperactive Disorder (ADHD). based on the relationship between accuracy. reaction time and event-related potentials (ERPs). Our results show differences between the analyzed groups with respect to markets for electrophysiological activity and reaction time. but not for accuracy In consequence, we Suggest that research in IL should explore different indicators and their relationship with the cognitive processing levels involved In addition, IL might involve different forms of information processing in normal children and children with ADHD. We discuss the possible impact of these findings for future research (C) 2009 Elsevier Inc All rights reserved

    Study of a set of reading precursors among Chilean children with Down syndrome
    (2023) Arango, Paulina S.; Escobar, Jose P.; Orellana, Pelusa; Aparicio, Andres; Strasser, Katherine; Rosas, Ricardo; Tenorio, Marcela
    Learning to read for children with Down syndrome is relevant because of the impact this ability has on learning and the development of autonomy. Previous research has described reading development in this population, but it is not clear if the process and precursors are the same in a transparent language like Spanish. This study explores performance in a set of precursors (phonological awareness, visual recognition, vocabulary, letter knowledge and verbal reasoning) in 42 children with Down syndrome between 6:0 and 10:11 years. We hypothesized that the participants would have a lower performance than previously reported with children with typical development, particularly in tasks of phonological awareness, because the method for reading instruction in Chile with this population is usually the global method. Our results show that the precursors improve with age, that there are differences in performance between the skills assessed, and the ceiling effect was not observed as would be expected for children with typical development for the abilities assessed at these ages, which suggests that in the children assessed the precursors are not consolidated at these ages. These results suggest that the stimulation of phonological awareness and other reading precursors in children with Down syndrome is important for reading development.

    Transformations of the rememberer: Development trajectories and the recall of historical events
    (FUNDACION INFANCIA APRENDIZAJE, 2012) Tenorio, Marcela; Aparicio, Andres David
    The goal of this paper is to present empirical evidence supporting the transformation of recall abilities along the life cycle, specifically those tied to socio-culturally relevant historical events. Two groups, 42 old adults and 22 young adults, participated in two studies designed to analyse fluidity and accuracy in experimental tasks. The results consistently show that old adults outperform young adults: they achieve better rates of fluidity recalling historical events and better rates of accuracy both in recognising and dating them. We theorise that the autobiographical memory system acts as an implicit scaffold that facilitates the task for old adults, thus explaining the transformation. As we advance along the development trajectory, we become "native rememberers" and, as such, recalling historical events becomes a natural and expert task.
