In this study, normative data for typicality and familiarity in presented that can be used for research in semantic memory experiments in Portugal. Measures of typicality (Rosch, 1975) and familiarity (Larochelle {\&} Saumier, 1993) were obtained with a sample of university students (n=195) for 16 semantic categories. Experimental evidence is also presented that supports the reliability of the normative data.
