This study describes a methodological proposal of how to approach retrospective protocols with the aim at increasing reliability and avoiding using it conveniently as a "crutch" for the key-logging analysis. This proposal involves exploring the notions of represantation (Chi 2006a, 2006b) and segmentation (Dragsted 2004) as two related variables that can be explored by using retrospective protocols and key-logging data, respectively. Adopting two correlated concepts that can be approached with similar measures, but by using different, equally informative methods, can provide relevant insights to the understanding of the translation process. The proposal is supported by the results of a pilot experiment triangulating represantation (as captured through retrospective protocols) and segmentation (as captured through key logging).
