ABSTRACT
Inhibitory control is a crucial cognitive-control ability for behavioral flexibility that has been extensively investigated through action-stopping tasks. Multiple neurophysiological features have been proposed to represent 'signatures' of inhibitory control during action-stopping, though the processes signified by these signatures are still controversially discussed. The present study aimed to disentangle these processes by comparing simple stopping situations with those in which additional action revisions were needed. Three experiments in female and male humans were performed to characterize the neurophysiological dynamics involved in action-stopping and - changing, with hypotheses derived from recently developed two-stage 'pause-then-cancel' models of inhibitory control. Both stopping and revising an action triggered an early broad 'pause'-process, marked by frontal EEG ß-bursts and non-selective suppression of corticospinal excitability. However, partial-EMG responses showed that motor activity was only partially inhibited by this 'pause', and that this activity can be further modulated during action-revision. In line with two-stage models of inhibitory control, subsequent frontocentral EEG activity after this initial 'pause' selectively scaled depending on the required action revisions, with more activity observed for more complex revisions. This demonstrates the presence of a selective, effector-specific 'retune' phase as the second process involved in action-stopping and -revision. Together, these findings show that inhibitory control is implemented over an extended period of time and in at least two phases. We are further able to align the most commonly proposed neurophysiological signatures to these phases and show that they are differentially modulated by the complexity of action-revision.
ABSTRACT
Actualmente, y en el contexto del estadode emergencia sanitaria, se han implantadouna serie de medidas de prevención y contenciónaplicables a toda la población. Enparticular, los centros sociosanitarios hantenido que adaptarse, diseñando medidasespeciales y aplicando planes de contingencia,que han provocado modificaciones en elentorno habitual de los residentes. Con elfin de observar los efectos de la pandemiasobre la conducta de personas con discapacidadintelectual residentes en un centrosociosanitario, se aplicó el Inventario parala Planificación de Servicios y ProgramaciónIndividual (ICAP). Los resultados, comparadoscon evaluaciones previas a la pandemiapor COVID-19, mostraron que el funcionamientoadaptativo era similar al anterior aeste periodo, pero existía un déficit en destrezasmotoras y en las destrezas de la vidaen comunidad. Así mismo, las alteracionesdel comportamiento habían aumentado, tantoen la puntuación general como en cadauno de sus índices específicos. Además, seencontró una relación inversa entre la edady la conducta adaptativa y una correlación positiva entre la edad y las alteraciones de la conducta. (AU)
Currently, and due to the existing healthemergency context, prevention and containmentmeasures applicable to the entirepopulation have been implemented. In particular,social and health centers have hadto adapt, designing a package of specialmeasures and applying guidelines and contingencyplans that have caused changes inthe habitual environment of the residents.In order to observe the effects of the pandemicon people with intellectual disabilitiesin social health centers, the Inventoryfor Client and Agency Planning (ICAP) wasapplied. The results, compared to previousevaluation, showed that adaptive functioningwas similar to that before this period,but there was a decrease in motor and socialskills. Furthermore, behavioral problems hadincreased, in the general index and in each of its specific index. In addition, an inverse relationship was found between age and adaptive behavior and a positive correlation between age and behavior disorders. (AU)

Los niños con cardiopatías congénitas tienden a presentar dificultades en la adquisición de pautas madurativas y en su conducta adaptativa. Se estudió su relación con los estilos de crianza generados por el estrés que genera la enfermedad. Objetivo: Evaluar calidad de vida y conducta adaptativa de niños de edad preescolar con diagnóstico de cardiopatías congénitas atendidos por el equipo de Seguimiento de Recién Nacidos de Alto Riesgo del Hospital Garrahan. Diseño: observacional, prospectivo, transversal. Población: niños con cardiopatías congénitas, que cumplan con los criterios de inclusión y brinden consentimiento. Instrumentos de medición: Cuestionario PedsQ 4.0, Adaptative Behavior Scales, Vineland-II. Adicionalmente se registraron datos obtenidos en entrevistas con niños y cuidadores. Los datos se analizaron con STATA 9.0. Resultados: muestra constituida por 47 pacientes, mediana de 3,9 años, 57% masculinos, 74% procedentes del conurbano, 34% resolución quirúrgica completa, 98% con necesidades básicas satisfechas, 72% madre ama de casa, con dedicación exclusiva al cuidado del hijo, 97,87% con redes de apoyo. La percepción de calidad de vida fue alta. La conducta adaptativa arrojó puntuaciones bajas en las áreas Comunicación 95,74%, Socialización 53,19% y Motricidad 100%, en área Habilidades de la vida cotidiana el 51% tuvo puntajes adecuados. En las entrevistas se evidenció que las familias conviven con temor a que su hijo se descompense, la enfermedad condiciona la relación con la familia, los niños reciben trato privilegiado y crianza permisiva. Los padres tienen dificultades para delegar los cuidados en otra persona y los niños son tímidos e inseguros con baja tolerancia a la frustración (AU)
Children with congenital heart defects have difficulties attaining developmental milestones and in their adaptive behavior. Association between these difficulties and styles of child rearing generated by disease-related stress was studied. Aim: To evaluate quality of life and adaptive behavior of preschool children with congenital heart defects seen by the team of Follow-up of High-Risk Neonates at Hospital Garrahan. Design: Observational, prospective, cross-sectional. Population: Children with congenital heart defects that met the inclusion criteria and signed informed consent. Measurement instruments: PedsQL questionnaire 4.0, Adaptive Behavior Scales, VinelandII. Additionally, data obtained from interviews with the children and caregivers were recorded. Data were analyzed using STATA 9.0. Results: The sample consisted of 47 patients; median age 3.9 years; 57% were male, 74% came from Greater Buenos Aires; in 34% the defect was corrected with complete surgical repair. In 98% basic needs were satisfied, in 72% the mother was a housewife taking exclusive care of the child, 97.87% had access to support networks. The perception of quality of life was good. Adaptive behavior yielded low scores in the area of Communication in 95.74%, Socialization in 53.19%, and Motor skills in 100%; in the area of Skills of daily living 51% had an adequate score. The interviews showed that the families lived in the fear that the child would decompensate, that the disease conditioned family relationships, that the children received a privileged treatment and were raised permissively. The parents have difficulties delegating the care to other persons and the children are shy and insecure with a low frustration threshold (AU)

Las políticas educativas en Chile han impulsado la evaluación de la conducta adaptativa como criterio de discapacidad intelectual, con el fin de establecer los apoyos requeridos por los estudiantes. Esta iniciativa es tan reciente como pionera y el artículo se propone evaluarla en relación con el marco normativo que regula y orienta las actividades profesionales vinculadas a ella.El trabajo realiza una revisión documental del contexto científico de la evaluación de la conducta adaptativa, analiza la coherencia entre dicho contexto y la política educativa chilena y elabora algunas sugerencias para el mejoramiento de la política y el desarrollo de capacidades profesionales. Este último aspecto resulta de la identificación de ciertas limitaciones en el marco normativo así como de la insuficiencia de recursos humanos capacitados para su implementación.
The educational policies in Chile have impelled the evaluation of adaptative behavior as a criterion of intellectual disability, so as to establish the supports required by the students. This initiative is both recent and pioneering and the article aims at evaluating it in relation to the normative framework that regulates and orients the professional activities connected to it. The work involves a documentary revision of the scientific context of the evaluation of adaptative behavior; it analyzes the coherence between said context and the Chilean educational policy and it presents some suggestions for improving the policies and the development of professional capacities. The latter aspect results from the identification of certain limitations in the normative framework as well as from the scarcity of trained human resources for its implementation.
