Normative data of 269 Spanish word fragments from the extension of Dasí, Soler and Ruiz (2004) database.

Abstract

In this article normative data of 269 Spanish word fragments from the extension of Dasí, Soler and Ruiz (2004) database are presented. The new database includes the following indices: difficulty; familiarity; number of meanings; frequency; number of letters given in the fragment; first/last letters given; ratio of letters to blanks; affective valence and activation. The analyses performed has obtained a replication of the experimental effects of frequency, difficulty and priming. These results confirm that the fragment completion task (with study and test phases) is an appropriate implicit memory test. We have performed two factorial analyses, obtaining three factors: lexical factor; perceptual factor; and affective factor. The subsequent regression analysis using factor scores as predictors indicated that difficulty is loaded by lexical and perceptual factors. Results on priming only showed significant influence of the lexical factor. A cubic fitting model between priming and difficulty found that 0.32 is the optimum difficulty level to get the highest priming level. Moreover, a quadratic model (boomerang figure) was the best to explain the relation between affective valence and activation.
