Abstract
[ES] Diversos estudios han encontrado de forma consistente que la connotación emocional influye en el reconocimiento visual de palabras (e.g., Kousta, Vinson & Vigliocco, 2009; Kuperman, Estes, Brysbaert & Warriner, 2014). En concreto, investigaciones recientes en español han encontrado que la valencia negativa de las palabras se relaciona con una latencia de respuesta mayor en la tarea de decisión léxica (TDL; Padrón, Fraga & Perea, 2017; Padrón, Isdahl-Troye & Fraga, 2017). El objetivo central de este trabajo fue investigar si también la activación emocional (arousal) de las palabras afecta a la ejecución (tiempos de respuesta y errores) en dicha tarea y si ese efecto es lineal o no. Puesto que el efecto del arousal sería principalmente temprano (Citron, 2012; Recio, Conrad, Hansen, & Jacobs, 2014), se manipuló asimismo la calidad perceptiva de los estímulos, una variable que afecta a estadios tempranos del procesamiento léxico. Los resultados obtenidos no mostraron un efecto consistente del arousal, ni tampoco una interacción significativa entre arousal y calidad perceptiva, aunque sí se encontró una tendencia a leer más rápidamente las palabras negativas muy activadoras.

More specifically, some recent research in Spanish using the lexical decision task (LDT) has shown that negative valence is related to slower responses (Padrón, Fraga & Perea, 2017; Padrón, Isdahl-Troye & Fraga, 2017). The aim of this study is to explore whether arousal also affects LDT performance (i.e., response times and errors), and whether this effect is linear or not. It is known that arousal effects tend to appear early in processing (Citron, 2012; Recio, Conrad, Hansen, & Jacobs, 2014). For this reason, we also manipulated the perceptual quality of the stimuli, a variable that affects early encoding processes. The results did not show a consistent effect of arousal during word recognition or a significant interaction between arousal and stimulus quality. Nonetheless, there is a trend for high arousal negative words to be read faster.
