\label{abstract}
Cognitive processing has been studying for several years. In order to avoid a possible confounding when studying the cognitive mechanisms that underlie the process of words and its corresponding concepts it is of great value to use controlled materials. Normative studies provide indices that can be used to control or/and manipulate the stimuli. Affective system has been stablished as a possible modulator of cognition and its relationships has become a first order question to be answered among cognitive researchers. In order to provide researchers with a wide set of potential material to be used, we obtained norms of emotional valence for 1915 Spanish words, but in order to enlarge the extent of its applicability, we obtained the ratings from Colombian participants. A total of 245 participants took place in this study. Ratings were obtained by using an online software named Qualtrics, which permits to automatized the process and thus reduce the error derived from pencil-and-paper applications. Results obtained show mean scores, standard deviations and number of observations for each word. Thus, the present study outcome represents a new and useful tool to be used by researchers interested in unravelling the mechanism underlying not only cognitive or affective processing but also the relationships exiting between these two systems.
