Age is known to affect prefrontal brain structure and executive functioning in healthy older adults, patients with neurodegenerative conditions and TBI. Yet, no studies appear to have systematically investigated the effect of age on cognitive performance in patients with focal lesions. We investigated the effect of age on the cognitive performance of a large sample of tumour and stroke patients with focal unilateral, frontal (n=68), or non-frontal lesions (n=45) and healthy controls (n=52). We retrospectively reviewed their cross sectional cognitive and imaging data. In our frontal patients, age significantly predicted the magnitude of their impairment on two executive tests (Raven's Advanc…

Neuropsychological group study methodology is considered one of the primary methods to further understanding of the organisation of frontal ‘executive’ functions. Typically, patients with frontal lesions caused by stroke or tumours have been grouped together to obtain sufficient power. However, it has been debated whether it is methodologically appropriate to group together patients with neurological lesions of different aetiologies. Despite this debate, very few studies have directly compared the performance of patients with different neurological aetiologies on neuropsychological measures. The few that did included patients with both anterior and posterior lesions. We present the first co…
Short and Long-Term Trainability in Older Adults: Training and Detraining Following Two Years of Multicomponent Cognitive—Physical Exercise Training
2020
Despite the benefits of multicomponent physical&ndash
2021
BackgroundExecutive functions underlie self-regulation and are thus important for physical activity and adaptation to new situations. The aim was to investigate, if yearlong physical and cognitive training (PTCT) had greater effects on physical activity among older adults than physical training (PT) alone, and if executive functions predicted physical activity at baseline, after six (6m) and twelve months (12m) of the interventions, one-year post-intervention follow-up and an extended follow-up during COVID-19 lockdown.MethodsData from a single-blinded, parallel-group randomized controlled trial (PASSWORD-study, ISRCTN52388040) were utilized. Participants were 70–85 years old community-dwel…
Online Adaptation to Altered Auditory Feedback Is Predicted by Auditory Acuity and Not by Domain-General Executive Control Resources
2018
Published: 12 March 2018 When a speaker's auditory feedback is altered, he adapts for the perturbation by altering his own production, which demonstrates the role of auditory feedback in speech motor control. In the present study, we explored the role of auditory acuity and executive control in this process. Based on the DIVA model and the major cognitive control models, we expected that higher auditory acuity, and better executive control skills would predict larger adaptation to the alteration. Thirty-six Spanish native speakers performed an altered auditory feedback experiment, executive control (numerical Stroop, Simon and Flanker) tasks, and auditory acuity tasks (loudness, pitch, and …

However, current dual-task tests appear to be insufficient for early diagnosi…
Mental fatigue induced by prolonged self-regulation does not exacerbate central fatigue during subsequent whole-body endurance exercise
2015
International audience; It has been shown that the mental fatigue induced by prolonged self-regulation increases perception of effort and reduces performance during subsequent endurance exercise. However, the physiological mechanisms underlying these negative effects of mental fatigue are unclear. The primary aim of this study was to test the hypothesis that mental fatigue exacerbates central fatigue induced by whole-body endurance exercise. Twelve subjects performed 30 min of either an incongruent Stroop task to induce a condition of mental fatigue or a congruent Stroop task (control condition) in a random and counterbalanced order. Both cognitive tasks (CTs) were followed by a whole-body …
Memoria Autobiográfica y Atención. Perspectiva Cognitiva y Experimental.
2017
RESUMEN TESIS Título: Memoria Autobiográfica y Atención. Una perspectiva cognitiva y experimental. Doctoranda: Ana Isabel Agustí López Director de tesis: Juan Carlos Meléndez Moral Este trabajo plantea dos cuestiones u objetivos generales, en primer lugar se pretende comprobar si al estudiar la memoria autobiográfica (MA) existen diferencias entre jóvenes y adultos mayores no solamente en relación al tipo de memoria (episódica y semántica) sino también en relación al componente emocional asociado a los recuerdos y la distribución temporal del recuerdo (infancia/ adolescencia, bump de reminiscencia y recuerdos recientes). En segundo lugar, se pretende estudiar la atención mediante tareas de …
Análisis del procesamiento local y global en adolescentes con trastorno del espectro autista de alto funcionamiento (síndrome de Asperger)
2017
El síndrome de Asperger (SA), actualmente incluido en el Trastorno del Espectro Autista (TEA), es el perfil cognitivo dentro del autismo que más cercano se encuentra al perfil de desarrollo típico, debido a que no muestra deterioro intelectual ni del lenguaje (a excepción de los procesos más complejos). La adolescencia es un período del desarrollo en el que la maduración física y sexual así como los cambios psicológicos y sociales se van dando progresivamente en la persona, que abandona la infancia para ir adentrándose progresivamente en la etapa adulta. La mayor capacidad de adaptación de las personas con SA (respecto al autismo de bajo funcionamiento) tiene como consecuencia que las mayor…
