Tracking Changes in Frontal Lobe Hemodynamic Response in Individual Adults With Developmental Language Disorder Following HD tDCS Enhanced Phonologic…

2020

Background: Current research suggests a neurobiological marker of developmental language disorder (DLD) in adolescents and young adults may be an atypical neural profile coupled with behavioral performance that overlaps with that of normal controls. Although many imaging techniques are not suitable for the study of speech and language processing in DLD populations, fNIRS may be a viable option. In this study we asked if fNIRS can be used to identify atypical cortical activation patterns in individual adults with DLD and track potential changes in cortical activation patterns following a phonological working memory training protocol enhanced with anodal HD tDCS stimulation to the presuppleme…

Working memory (WM) performance declines with age. However, several studies have shown that WM training may lead to performance increases not only in the trained task, but also in untrained cognitive transfer tasks. It has been suggested that transfer effects occur if training task and transfer task share specific processing components that are supposedly processed in the same brain areas. In the current study, we investigated whether single-task WM training and training-related alterations in neural activity might support performance in a dual-task setting, thus assessing transfer effects to higher-order control processes in the context of dual-task coordination. A sample of older adults (…

La inhibición, el autocontrol emocional, la memoria de trabajo y la supervisión ¿predicen las manifestaciones típicas de adultos con TDAH?

2019

Introducción. Los déficits en inhibición, control emocional, memoria de trabajo y supervisión se han evidenciado en numerosas investigaciones focalizadas en el trastorno por déficit de atención con hiperactividad (TDAH), pero la información sobre su posible influencia diferencial en las manifestaciones características del trastorno es escasa. Objetivos. El presente estudio se propuso analizar las relaciones de las funciones ejecutivas de regulación (inhibición y control emocional) y metacognitivas (memoria de trabajo y supervisión) con manifestaciones del TDAH y determinar el poder de predicción de esas cuatro funciones ejecutivas en dichas manifestaciones. Método. Sesenta y un jóvenes adul…

Topical Review: Functional Anatomy of Human Hippocampal Formation and Related Structures

1996

Data on the internal organization, and neuronal connections of the human hippocampal formation and related structures of the limbic system are briefly reviewed. In the healthy brain, somatosensory, visual, and auditory input proceeds through neocortical core and belt fields to a variety of association areas, and from here the data is transported via long cortico-cortical pathways to the extended prefrontal association cortex. Tracts generated from this highest organizational level of the brain guide the data via the frontal belt (premotor cortex) to the frontal core (primary motor area). The striatal and cerebellar loops provide the major routes for this data transfer. The main components o…

RELIABILITY AND VALIDITY OF THE LATVIAN VERSION OF THE COMPUTERIZED EXECUTIVE FUNCTIONS TEST “EXAMINER” IN A STUDENTS SAMPLE: RESULTS OF THE PILOT ST…

2016

The aim of this pilot-study was to assess reliability and validity of the Latvian version of the computerized executive functions test EXAMINER (Executive Abilities: Measures and Instruments for Neurobehavioral Evaluation and Research) in a sample of high school students and university students. The adaptation procedure included translation of the instructions and technical configuration of the test’s computerized version. The Latvian version of the EXAMINER includes tasks that measure executive functions of inhibition, set shifting and working memory updating. Participants included two sub-groups: 22 (14 males, 8 female) students from high school and 39 students (11 males, 28 female) from …

Cognition and interpersonal communication: The effect of voice quality on information processing and person perception

2014

Abstract Against the backdrop of cognitive load theory (CLT) it was tested if irregular voice increases processing demands on working memory (WM). An experiment was designed to expose N = 54 participants to expository text delivered with a modal and a creaky human voice. Working memory capacity was measured by a secondary task on the visual modality. Listening to a creaky voice quality consumes more cognitive capacity as indicated by the significant decrease in secondary task performance; also, retention of information was found to be impaired. Results are explained within the framework of CLT and implications for professional communication are discussed.

MEMORIA DE TRABAJO EN NIÑOS DE EDUCACIÓN INFANTIL CON Y SIN BAJO RENDIMIENTO MATEMÁTICO

2014

Abstract:This study aims to explore working memory in preschool children with and without low mathematical performance. The sample consisted of 255 children aged 5-6 years, to whom were administered neuropsychological tests of working memory and TEDI-MATH to estimate the mathematical performance. The results highlight the capacity of verbal working memory to significantly differentiate groups of children with and without problems in 8 of the 9 analyzed mathematical domains. This factor together with visuospatial working memory differentiate the group of children at risk for mathematical learning disabilities.Keywords: working memory, preschool, math performance, mathematics learning disabil…

Hey Teacher, Don’t Leave Them Kids Alone: Action Is Better for Memory than Reading

2017

International audience; There is no consensus on how the enactment effect (EE), although it is robust, enhances memory. Researchers are currently investigating the cognitive processes underlying this effect, mostly during adulthood; the link between EE and crucial function identified in adulthood such as episodic memory and binding process remains elusive. Therefore, this study aims to verify the existence of EE in 6–10 years old and assess cognitive functions potentially linked to this effect in order to shed light on the mechanisms underlying the EE during childhood. Thirty-five children (15 second graders and 20 fifth graders) were included in this study. They encoded 24 action phrases f…

La Transición, ¿un mito creado por y para la televisión

2015

This article deals with the representations of Spanish transition to democracy shown by television in Spain from 1995 to nowadays. Without claiming to be exhaustive, it analyses the recycling as well as the re-creating of scenes and figures which already belong to History although they are still present in collective memory. The analysis of a few fictional and informative programmes will enable us to sketch out a cartography of the representations of the transition on television. We will see how they get organized around TV formats and genres (series and mini-series, biopics and political thrillers), how they are related to other previous programmes or, on the contrary, how they attempt to …
