Potenciales evocados como marcadores de riesgo para el alcoholismo
(Universitat de Barcelona, 1991)En este informe se presenta una revisión de trabajos acerca de la utilización de distintos componentes de los potenciales evocados como marcadores de riesgo para desarrollar alcoholisrno. Los jóvenes procedentes de familias ... -
Estudio de la reversibilidad de las alteraciones del sistema nervioso en alcohólicos crónicos abstinentes mediante potenciales evocados
(Universitat de Barcelona, 1991)A one year follow-up study was performed on 50 abstinent chronic alcoholic patients. Three different kinds of evoked potentials were used: Short and Long Latency Auditory Evoked Potentials (BAEPs and LAEPs) and Visual ... -

Field dependence-independence and brain organization: the confluence of two different ways of describing general forms of cognitive functioning? A theoretical review
(SAGE PublicationsAmmons Scientifics, 1993)We reviewed a total of 67 studies of the relationship between the cognitive style dimension of field dependence-independence and brain organization. To date, such studies have followed three basic lines of approach: (1) ... -
Reversibility of brain-stem evoked potential abnormalities in abstinent chronic alcoholics: one year follow-up
(Elsevier, 1994)Brain-stem auditory evoked potentials (BAEPs) were studied in 34 chronic alcoholics who had been abstinent for 1 year, and in age- and sex-matched control subjects. The patients were examined 3 times, at 1 month, 5 months ... -

Datos de estímulo único versus datos de elección preferencial en estudios sobre calidad ambiental
(Colegio Oficial de Psicólogos del Principado de Asturias, 1996)Los estudios sobre calidad ambiental resultan de gran interés en el estudio de las relaciones individuo-entorno. Sin embargo, las diferencias teóricas y metodológicas existentes entre los distintos investigadores han ... -
Visual and auditory event-related potentials in young children of alcoholics from high- and low-density families
(Wiley, 1998)Event-related potentials (ERPs), particularly the P3 wave, have been proposed as biological markers of genetic risk for alcoholism. The present study assesses the ERPs from 102 boys and girls (7 to 15 years old) divided ... -
Event-related potentials elicited by infrequent non-target stimuli in young children of alcoholics: Family history and gender differences
(Oxford University Press, 1998)This article analyses the visual and auditory event-related potentials (ERPs) elicited by infrequent non-target stimuli in young children with alcoholic fathers. The aim was to study the characteristics of the ERP waves ... -
Mismatch negativity in young children of alcoholics from high-density families
(Wiley, 1998)The mismatch negativity (MMN) component of event-related potentials was recorded from a group of young children of alcoholics (n = 19, 8 females) with a high-density family history of alcoholism and from a control group ... -
Características neuropsicológicas de los sujetos de alto riesgo al alcoholismo: en busca de marcadores de vulnerabilidad familiar
(Universitat de Barcelona, 1999)Este trabajo revisa los estudios de alto riesgo al alcoholismo que han examinado las características neuropsicológicas de los hijos de alcohólicos con el fin de profundizar en la vulnerabilidad familiar a este trastorno. Los ... -
Neuropsychological characteristics in children of alcoholics: familial density
(Alcohol Research Documentation, 1999)Objective: The purpose of high-risk studies is to find characteristics that allow the identification of subjects with a higher vulnerability to alcoholism. The aim of this research was to verify if the familial density ... -
The effects of stimulus intensity and age on visual-evoked potentials (VEPs) in normal children
(Wiley, 1999)In this study, we explored the effects of flash intensity and age on visual-evoked potentials (VEPs) in a sample of 85 children aged 8–15 years. Results of previous studies are discrepant regarding the extent to which ... -
Event-Related Potentials Elicited by a Visual Continuous Performance Task in Children of Alcoholics
(Elsevier Masson, 1999)Event-related potentials (ERPs) were recorded from a group of young children of alcoholics (HR; n -17, 7 females) with a high-density family-history of alcoholism and from a control group (CN; n -19, 10 females), ages 7–15 ... -
Visual P3a in Male Subjects at High Risk for Alcoholism
(Elsevier, 1999)Background: Voltage of the P300 component of eventrelated potentials (ERPs) has been proposed as a phenotypic marker of risk for alcoholism. P3a elicited by intrusive events is important in the context of deficits ... -

(Asociación Española de Estudios en Drogodependencias, 2000) -
The effect of motivational instructions on P300 amplitude
(Elsevier Masson, 2000)The aim of this investigation was to determine the effect on P300 amplitude of instructions aimed at increasing the subject’s degree of task involvement. To this end, two different studies were carried out. In Study 1, ... -
Middle-latency auditory evoked potentials in children at high risk for alcoholism
(Elsevier, 2001)Purpose. In the course of a high-risk study for alcoholism, the middle-latency auditory evoked potentials (MAEPs) of children of alcoholics were explored. Material and Methods. A series of auditory clicks (0.1 ms, 60 dB ... -
Interference of Cellular Phone Conversations with Visuomotor Tasks: An ERP Study
(Hogrefe, 2001)The use of mobile phones has been shown to increase drivers’ reaction times (RTs), but whether this results from interference with attention, stimulus identification, or response production remains unclear. We recorded ... -
