The Journal of Specialised Translation Issue 33 – January 2020 129 Electrodermal activity as a measure of emotions in media accessibility research: methodological considerations Anna Matamala, Olga Soler-Vilageliu, Gonzalo Iturregui-Gallardo, Universitat Autònoma de Barcelona Anna Jankowska, Universitat Autònoma de Barcelona and Jagiellonian University in Kraków Jorge-Luis Méndez-Ulrich, Anna Serrano Ratera, Universitat Autònoma de Barcelona ABSTRACT This article proposes electrodermal activity (EDA) as a new objective measure for experimental studies in media accessibility. It first presents a theoretical framework in which the concept of emotion and its categorisation are presented. It then explains how EDA can be used to measure emotional reaction: the article reports on experimental design, participant selection, stimuli preparation, data collection devices, experimental procedure and data analysis. It also discusses briefly how EDA can be combined with other measures. Overall, the article provides a general methodological framework for the implementation of electrodermal activity as a measure of emotions in media accessibility research. KEYWORDS Media accessibility, reception studies, electrodermal activity, psychophysiology, emotions. 1. Introduction Reception research is taking a leading role in audiovisual translation (AVT) and media accessibility (MA), and various methodological approaches are being adopted to investigate audience reactions. Researchers are moving from text-based or speculative studies towards experiments grounded in objective data obtained through diverse devices (Rojo et al. 2014; Szarkowska et al. 2016; Chmiel et al. 2017). This paper focuses on a relatively new measure for AVT and MA, which is used as an indirect indicator of emotional arousal: electrodermal activity (EDA). In section 2, we set up the theoretical framework, briefly revising research on accessibility services, defining what an emotion is, and introducing the concept of EDA and its measurement. Section 3 proposes the methodology for designing studies using EDA. We report on design, participants selection, stimuli preparation, devices for data collection, and provide some indications on the experimental procedure and data analysis. In section 4 we discuss other measures that can be combined with EDA. The last section summarises the concepts presented in the paper and draws some conclusions. This article has been written on the basis of the experience gained through the NEA project (pagines.uab.cat/nea), in which EDA has been
