Patrones electrodérmicos de la actividad grupal

Abstract

Se presenta el registro de la actividad electrodérmica de los grupos (EDAg) en el ámbito de investigación de las Neurociencias Sociales. El objetivo general es aportar un parámetro psicofisiológico (EDAg) que registre los niveles de activación (atencional y emocional) para analizar el comportamiento grupal como unidad sociofísica. La investigación en las Neurociencias ha delimitado sus niveles de análisis desde lo molecular, celular, de sistemas, conductual y cognitivo tanto en el nivel intra- interpersonal e intergrupal. La propuesta actual permite analizar la activación del grupo como unidad integrada a nivel intragrupal con el registro de la actividad electrodérmica grupal a través de Sociograph (Martínez y Garrido, 2003). Este enfoque implica un cambio de visión en el análisis de la medición de la actividad electrodérmica, incorporando las características técnicas de la EDA a nivel individual (nomenclatura, métodos, procedimientos, componentes electrodemográficos, parámetros e índices y bases electrofisiológicas) al grupal con la EDAg. Esta perspectiva de estudio requiere la conceptualización del grupo como unidad de análisis estructurada, dinámica, integrada y sincrónica que se articula a través de la interacción, interdependencia e intercambio constituyendo un nivel de activación conjunta. Sociograph mide la respuesta integrada de un conjunto de sujetos (grupo), eliminando la variabilidad individual para destacar la actividad propia del grupo realizando un seguimiento de su actividad en tiempo real y continuo del nivel de activación atencional (EDLg) y su reactividad emocional (EDRg). Se plantea delimitar patrones de activación psicofisiológicos de la actividad grupal (VD) discriminando un nivel de activación del nivel individual distinto al que se genera durante la actividad grupal. La muestra de la investigación es de 211 grupos que corresponden a 790 sujetos distribuidos en grupos de cinco personas. La definición operativa del grupo (Bunge, 1981) asociada a la interacción (VI1) y a las tareas grupales (VI2) describe el diseño de la investigación. Se registra la actividad electrodérmica del grupo (VD) durante la interacción (VI1) en dos dimensiones: (a) en la forma en que se realiza la actividad (co-presencia Vs. actividad grupal) y (b) la medición de ésta de dos formas: una sola medición del grupo (Grupo G) y Grupos en Evolución (GE)) durante la realización de tareas grupales (VI 2). La principal hipótesis de trabajo expone que existirá una señal de activación Grupal medida por Sociograph, como integración de las señales individuales que será distinta según el nivel de interacción e interdependencia de los sujetos experimentales del grupo. La posibilidad de realizar un registro psicofisiológico del grupo en tiempo real y continuo supone un avance cualitativo sustancial para el desarrollo de nuevas metodologías de investigación grupal.

The overall objective is to provide a psychophysiological parameter (EDAg) that registers the activation levels (attentional and emotional) to analyze group behavior as sociophysical unit. Research in social neuroscience has identified levels of analysis from the molecular, cellular, both behavioral and cognitive interpersonal intra- and inter- level systems. The current proposal to analyze the activation of the integrated group and intragroup level recording electrodermal activity group (EDAg) through Sociograph (Martinez & Garrido, 2003) unit. This approach involves a change of view in the analysis of the measurement of electrodermal activity incorporating the technical characteristics of the individual EDA (nomenclature, methods, procedures, etc.) to the EDAg group. This perspective requires the conceptualization of the study group as the unit of analysis structured, dynamic, integrated and synchronized to be articulated through the interaction, interdependence and sharing together constituting a level of activation. Sociograph measured integrated set of subjects (group) response, eliminating individual variability to highlight the activity of the group tracked their activity in continuous level of attentional activation (EDLg) real time and emotional reactivity (EDRg). The possibility of a psychophysiological recording is an important group for the development of new methodologies for group research qualitative advance.
