Selecting between Competitors in Multiplication Tasks: An Explanation of the Errors Produced by Adolescents with Learning Difficulties
1997
Two experiments were conducted in order to determine the nature of the difficulties encountered by learning disabled (LD) adolescents in the resolution of multiplication problems ( a b, where a and b vary between 2 and 9). A response production task (Experiment 1) revealed that the incorrect responses generally belonged to the table of one of the two operands, and that the order of difficulty of the problems was the same for the LDs as for normal children, adolescents, and educated adults as reported in the literature. This result suggests that the difficulties are not solely due to memory problems. Experiment 2 tested the hypothesis that these difficulties were caused by a problem in inhi…

Abstract This large-scale eye-movement study (N = 164) investigated how students read short task assignments to complete information search problems and how their cognitive resources are associated with this reading behavior. These cognitive resources include information searching subskills, prior knowledge, verbal memory, reading fluency, and attentional difficulties. In this study, the task assignments consisted of four sentences. The first and last sentences provided context, while the second or third sentence was the relevant or irrelevant sentence under investigation. The results of a linear mixed-model and latent change score analyses showed the ubiquitous influence of reading fluency…
Assessing hot and cool executive functions in preschoolers: affective flexibility predicts emotion regulation
2018
Affective flexibility (AF) is the ability to alternate between processing emotional and non-emotional information. This hot executive function has been understudied during early development. The fi...
Early mathematical skill profiles of prematurely and full-term born children
2017
Abstract Preterm birth is associated with low mathematical skills in children. This study on five-year-old Finnish children investigated whether mathematical skill profiles would differ between prematurely and full-term born children and how such profiles and other cognitive skills would be related. Mathematical skills included digit knowledge, spontaneous focusing on numerosity, arithmetic, counting and geometric skills. The investigated cognitive skills were phonological processing, working memory, instruction comprehension, speeded naming, inhibition and visuomotor skills. The participants were 119 preterm children with birth weight
El síndrome del cromosoma X Frágil: fenotipo conductual y dificultades de aprendizaje
2015
In this article, we describe the behavioral phenotype of individuals with Fragile X Syndrome and its impact in the educational scope. This syndrome is characterized by difficulties in sensory integration, cognitive deficits (verbal reasoning, abstract/ visual and cuantitative skills, short term memory, sequential processing, attention and executive processes), language disorders (phonetic-phonologicals, semanticals, morphosyntacticals and pragmaticals) and communication disorders, social anxiety, general hyperarousal, autism, non autistic social difficulties, attention deficit and hyperactivity, and learning disabilities. The behavioral phenotype is highly variable and depends on sex, age, …
Paired associate learning tasks and their contribution to reading skills
2016
Associative learning has been identified as one of several non-linguistic processes involved in reading acquisition. However, it has not been established whether it is an independent process that contributes to reading performance on its own or whether it is a process that is embedded in other linguistic skills (e.g., phonological awareness or phonological memory) and, therefore, contributing to reading performance indirectly. Research has shown that performance on tasks assessing associative learning, e.g., paired-associate learning (PAL) tasks, is lower in children with specific reading difficulties compared to typical readers. We explored the differential associations of two distinct ver…
Exploring working memory in children with low arithmetical achievement
2005
Abstract This research aimed at exploring the working memory functions in children with low arithmetical achievement and normal reading, compared to age matched controls (mean age 9 years). All the children completed a series of working memory tasks, involving the central executive functions (using both linguistic and numerical material), the phonological loop (using words, pseudo-words and digits) and the visual sketchpad (using both static visual-spatial patterns and visual-spatial sequences). Results indicated that poor arithmeticians performed worse than age-matched controls in all the visual sketchpad tasks and in all the central executive tasks, whether they used linguistic or numeric…
Reservoir computing model of prefrontal cortex creates novel combinations of previous navigation sequences from hippocampal place-cell replay with sp…
2019
As rats learn to search for multiple sources of food or water in a complex environment, they generate increasingly efficient trajectories between reward sites. Such spatial navigation capacity involves the replay of hippocampal place-cells during awake states, generating small sequences of spatially related place-cell activity that we call “snippets”. These snippets occur primarily during sharp-wave-ripples (SWRs). Here we focus on the role of such replay events, as the animal is learning a traveling salesperson task (TSP) across multiple trials. We hypothesize that snippet replay generates synthetic data that can substantially expand and restructure the experience available and make learni…
A beautiful flourish. The foundation story of Wroclaw (and Wroclaw residents)
2020
In the article, I present the content and the context of the foundation story of Wroclaw – created after 1945 in one of the largest and most destroyed cities which joined Poland after World War II (Polish Western and Northern Territories). The analyzed empirical material consists of personal documents – statements of Wroclaw residents written and submitted in 1966 for the competition entitled: “What does the city of Wrocław mean to you”. The most important element of this story about the creation of the city is the figure of a pioneer, shaped in the image of a mythical hero. The features of pioneers (such as courage, uncompromising love for the city and openness to others) have become an im…
I remember... Of Social Construction of Memory of the City Dwellers in the Western and Northern Territories on the Example of Wrocław
2017
Celem artykulu jest przedstawienie wątkow pamieci spolecznej, ktore z jednej strony opierają sie na indywidualnym, potocznym doświadczeniu jednostki, z drugiej umieszczane są w spolecznie wynegocjowanych ramach pamieci zbiorowej. Artykul ten wpisuje sie rowniez w dyskusje nad miejscami pamieci i ich mozliwą treścią – wykraczającą poza podtrzymujące pamiec zbiorową muzea, pomniki, upamietniające tablice czy cmentarze – realizowaną w codziennym zyciu jednostki. Przedmiotem analiz jest pamiec spoleczna mieszkancow Wroclawia, ich konstrukcje światow spolecznych opierające sie na przestrzeni miasta obciązonej obcą kulturowo „pamiecią nieobecnych”.
