Under the masked priming paradigm, it has consistently been shown that opaque and transparent words are facilitated relative to form-related controls, but differences in priming between one condition and another have not been conclusively proven. Hence, research has been unable to theoretically elucidate the possible value of semantic transparency in the processing of derived words. This study describes two lexical decision experiments in Spanish. Experiment 1 revealed differences between the transparent and orthographic conditions, with no differences between the other conditions in the analyses of the error rates. In the second experiment, the participants visited the laboratory on two occasions, separated by a week. The task was administered twice, with participants responding to one of the experimental lists on each day. The results of this second experiment revealed significant differences in the size of the priming effect of the opaque and transparent conditions compared to the form-related condition, but without differences between these two effects. We discuss these findings from the perspective of current models of visual lexical processing.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/journal article1747-0226https://doi.org/10.1177/174702182097703833176605https://journals.sagepub.com/doi/abs/10.1177/1747021820977038open accessLexical decision taskMasked primingMorphological processingSemantic transparencySpanishLogopediaPsicolingüística6104.01 Procesos Cognitivos6104.04 Psicolingüística
